Often, even experienced motorists who carefully monitor the condition of the car are faced with the fact that the engine simply does not start. And even such a reliable car as the Mazda CX5 can fail sooner or later. The cars of the Japanese automaker are quite complex in their internal structure, there are a lot of electronics and specific auto systems, but the simplest self-diagnosis can still be carried out.
Common Causes
If the Mazda CX 5 does not start, you must first check if everything is in order with the basic "start conditions":
- there is gasoline;
- the battery is charged;
- terminals are not damaged.
These failure causes are common for beginners, but can also puzzle an experienced, but tired or absent-minded driver. If the car immediately starts to make weak and strange sounds, as if it does not have enough power to scroll the starter, this is a reason to check the battery. In fact, the car does not even stall, but does not start at all. Mazda requires a good level of charge from the battery and at the same time the systems consume a lot of electricity.
Experienced owners know that batteries wear out quite quickly during such operation and should be changed in time. The way to correct this shortcoming is a simple “lighting”. But first, you should inspect the terminals: in wet weather, with high humidity, rust can significantly affect the condition of the internal components of the car. In addition, during long-term operation, they can simply move away.
The problem with gasoline is even easier to solve and also easy to diagnose. Even if it seemed that there was enough fuel, but the car still stalls, you should pay attention to its position. Mazda tanks have a fairly flat shape, and if the car is on a certain slope, gasoline simply flows into a corner inaccessible to the pump. You can try to just push the car on a flat surface.
Specific breakdowns
Mazda CX 5 is a car with many internal sensors. In addition, the manufacturer has taken care of an excellent self-diagnosis system of the machine. Therefore, if the car stalls, you should pay attention to whether any error has appeared. She can unambiguously tell the cause of the breakdown. If the situation repeats itself regularly, Mazda did not start up the first time, the best solution would be to go for diagnostics. Often the cause is a breakdown in the electronic control or in the electrical network. For the fifth model, this is quite typical.
You should also pay attention to how the car works during short stops. The fifth model is equipped with the i-stop function, but the car should not completely stall in working condition. However, sometimes that is exactly what happens. If the car starts immediately after this, you can try to recharge the battery. If the situation repeats after that, you should contact an authorized dealer, since it is almost impossible to cope with this system on your own.
Another weak point of this car is the petrol pump. The part itself is quite high quality, however, it is extremely sensitive to the quality of the fuel, but it often fails. If the car stalls regularly or does not start at all, you can try to connect the pump separately from the car in the service. Mazda owners need to remember that for these machines, regardless of model, the pump runs very quietly and therefore the absence of a sound of operation does not indicate a breakdown. Even the pump power cable can fail, which should also be taken into account. In this case, problems will appear regularly and only then the car will not start at all.
Another common malfunction of the fifth model may be associated with fuel quality - contamination of the throttle valve. This feature of the Mazda CX 5 is especially pronounced at slightly negative temperatures. For example, a car can start at minus 20, but not catch the ignition at minus 10. This is a common situation, so in the fall you should thoroughly rinse the damper. In general, this feature of the model is experienced by many owners of the Mazda CX 5 of the very first releases. The official version of the manufacturer is poor fuel quality.
As for any other Mazda, the following reasons for a poor start are also relevant for the CX 5:
- injector malfunction;
- breakage of candles;
- starter failure.
You can determine the poor "well-being" of candles even before the car does not start. The machine and engine in particular will not run as fast, and performance will drop significantly. It’s not worth waiting for a failure at startup, Mazda candles are not so expensive. As a preventive measure for such problems, you should regularly change the fuel filter and monitor the condition of the injector. Replacing these parts often solves the problem of the difficult start of the Mazda CX 5. The starter most often gives itself out through the headlights: if the optics burn brightly without a running engine and significantly lose light strength at the time of an unsuccessful start, it is most likely the starter solenoids.

The Japanese crossover is equipped with a large number of modern electronics, the correct operation of which largely depends on the quality and capacity of the battery. The correct choice and installation of the battery will help to avoid troubles on the road associated with the failure of the main components. The specifics of the Mazda CX-5 battery is the i-stop system. In this article, we will tell you everything about the features of the battery, give advice on choosing, share instructions for self-replacing and registering the battery.
How the battery works
The original Mazda CX-5 battery is installed by the manufacturer. It is responsible for the performance of all electrical components of the car. If the battery fails, the car cannot be started. Let's see what the principle of operation of this small but very important component is.
The functioning of the battery is entirely based on the conversion of chemical energy into electrical energy and vice versa. In addition, the device provides a constant current, and it is thanks to voltage stabilization that the motor can work normally.
The battery has two poles - positive and negative. The battery terminals are connected to the car, due to which the main mechanisms can perform their tasks without fail. Components that depend on an additional energy source include:
- engine;
- audio system;
- air conditioner;
- optics;
- glass cleaners, etc.
The principle of operation of the battery lies in the features of its structure. Often, a part consists of 6 cells, each of which contains 2 electrodes made of metal plates. This galvanic cell provides power to the vehicle.
Battery operation in i-stop mode
The battery for the Mazda CX-5 is subjected to enormous stress due to the operation of the i-stop system. This is due to the constant shutdown and start of the engine while the car is stopped. Thus, the owner receives reduced fuel consumption due to increased battery wear.
The largest current consumption is carried out at the time of starting the power unit. In the future, the partial discharge of the battery is compensated by recharging from the generator. When driving on the highway, the crossover battery is charged in standard auto mode, and every stop in the city activates the i-stop (while the generator is not working).
The effect of i-stop depends on the degree of charge. At SOC below 65%, the system refuses to function.
The procedure for disconnecting, connecting and replacing the Mazda CX-5 battery
The need to replace the battery on the Mazda CX-5 appears when the SOC charge level drops below 25%. At this rate, recovery is no longer possible. Even an inexperienced car owner can install, connect or remove the Mazda CX-5 battery on their own.
To dismantle the old battery you need:
- Disconnect the current sensor from the negative terminal to de-energize the on-board computer.
- Remove all terminals.
- Remove fixing bar.
Battery installation is carried out in the reverse order. The next step is registration and initialization of the battery.
Registration and initialization
In order for the battery to work properly, you need to know how to register the Mazda CX-5 battery. The procedure differs depending on the presence of the LCD screen. So, owners of cars without TFT LCD need to follow the instructions:
- turn off the engine;
- move the gearshift lever to position N;
- press and hold the brake pedal while performing further actions;
- long press the gas to activate the battery indicator;
- press and release the accelerator three times to deactivate the bulb;
- release the brake.
For a crossover with TFT LCD, the circuit is as follows:
- close doors;
- turn the ignition to the ON position without starting;
- use the INFO switch to clear the warning message;
- set the gearshift lever to the neutral position;
- hold the brake pedal by doing the following;
- turn on the accelerator for 5 seconds, wait for the indicator to activate;
- Press and release the gas 3 times (the beacon should turn off).
Also, after connecting a new battery and registering it, it is necessary to initialize the Mazda CX-5 battery, because when the terminals are disconnected, the settings are reset. The algorithm is the following:
- start and warm up the engine;
- hold and hold i-stop for 10 seconds;
- with the hood closed, turn the steering wheel from one extreme position to another;
- turn off the motor.
You can check if the initialization has passed by pressing the i-stop button. If the green light is on, it means that the battery fit into the work of all systems.
How to choose a battery for Mazda CX-5
The Japanese brand recommends installing an original Mazda CX-5 battery. This is due to the i-stop technology, on which the operation of the power unit of the machine is based. You can consult about the model in authorized service centers. The first generation crossover was equipped with Panasonic Q-85 batteries, but today the range has grown significantly, and such well-known brands as Exide, Bosch and many others have entered the market.
To understand which battery is on the Mazda CX-5, you need to carefully study the marking from the manufacturer. When choosing, it is important to pay attention to the overall dimensions, capacity and starting current. The battery capacity should be in the range of 40-70 A / h, the nominal voltage indicator is 12 V, the starting current is 300-700 A. You should also carefully consider the polarity of the device, the coincidence of the terminals. As for the dimensional characteristics, the small engine compartment requires to withstand them especially clearly. Owners of the 2.0 engine buy a battery 202x230x172 mm (HxLxW), for 2.2 liters they choose 202x255x172 mm. The cost of a new CX-5 battery starts from 6,500 rubles.
Battery marking, reviews
In order not to get confused by the abundance of the assortment and acquire the right part, it is important to be able to read the markings. The manufacturer puts a code on the product, deciphering which you can find out the main technical characteristics of the product.
What is indicated on the marking of a Japanese brand battery (JIS standardization):
- battery capacity Mazda CX-5;
- battery width, mm;
- battery length, cm;
- terminal arrangement, polarity (L or R).
According to the reviews of car owners, it was possible to find out that the brands Varta and Bosch are the most popular in Russia. These brands offer quality products at a competitive price. Good demand is noted for the Bosch S4 02 model (it has an inrush current indicator of 540 A and a capacity of 640 Ah). You need to understand that a car with a lot of electronics requires a high-capacity battery.
Possible problems
Like any part, the battery sooner or later becomes unusable. If the car does not start (especially in frosty weather), it is worth checking the battery performance. Possible problems:
- Battery leak. If the housing is swollen, the device must be replaced immediately. The cause of deformation may be an increased operating temperature.
- Bad smell of sulfur. This is a battery leak. Breakage is also accompanied by the appearance of rust on the terminals.
- Low fluid level. If the amount of liquid has dropped below the lead plates, top up or replace the battery.
In order for the battery, and with it all the electronics to function properly, it is necessary to carry out diagnostics. It can provoke a breakdown: violation of the temperature regime during operation, insufficient charging, low-quality electrolyte, and much more.
Outcome
Battery operation provides engine start and power to all electronic systems. To extend the life of the battery, it is important to charge it on time and adhere to the operating modes. If the need for replacement has already arisen, it is not necessary to seek help from a service station. Even an inexperienced car owner can carry out installation, registration and initialization on their own.
Sometimes it happens that the car is still Yesterday it started, but today it won't start.. Considering that most Mazda models with gasoline engines are started according to the same principle, regardless of the complexity of the engine control system and the number of sensors - the main answers to the question, what to do if mazda won't start, in difficult times, most likely to help most car owners.
- since the mid-1980s, it has been equipping cars with an electronic diagnostic system that allows you to determine the main problems of the sensors of the injection system. If there are, they must be eliminated, since there are both "harmless" errors and critical errors, in the presence of which the engine cannot be started. The latter include errors in the ignition system, crankshaft position sensor, etc.
- Battery and fuses. The battery must be sufficiently charged, the starter must spin easily. In some cases, cleaning the battery terminals from oxides helps. Cleaning is done with a metal file or a knife; it is not recommended to clean the battery contacts with sandpaper. All fuses must be intact.
- Spark. The spark on the candles should be powerful, blue (not red, not purple). If there is no spark or the spark is weak, the candles, the resistance of the BB wires for breaks, the resistance of the crankshaft position sensor for breaks, the exact match of the marks of the timing system, the contacts of the connectors on the distributor, the slider and the contacts inside the distributor are to be checked.
- Petrol. If, after an unsuccessful start of the engine, the candles are dry, the pressure in the fuel system, the contacts and the electrical circuit of the fuel pump, the main relay, the fuel lines, the fuel filter, the electronic part of the injectors for breaks or short circuits must be checked (usually, the injector resistance is 6-20 Ohm) . Gasoline must be of good quality, remember - maybe you refueled yesterday some liquid at an unfamiliar gas station, like . The octane number of the fuel in the tank must not be less than 95 (for most models, including previous years).
- air path. The air filter must be relatively clean, the rubber corrugation must be free of cracks and holes (even if they are carefully wrapped with electrical tape). The air path must be absolutely sealed as a whole, starting from the air intake and ending with the inlet to the intake manifold. Inside the air ducts and the air filter housing, there must be no foreign objects, such as a rag, imperceptibly sucked in by the air flow during engine maintenance. The contacts of the air flow sensor (MAF) connector are also subject to check for oxides or mechanical damage.
- Starter does not turn- in this case, the electrical circuit from the ignition system to the starter must be checked for breaks or shorts (this is very useful for your model), the immobilizer and the key, as well as the starter itself for wedging (disassembly of the device will be required). If the battery charge is insufficient, then the starter may not spin, while the lights in the cabin will light up, as if everything is in order. The starter test can be performed by connecting the wires from the battery directly to the starter contacts for no longer than 5 seconds. If at the same time the starter starts to spin, in this case the wiring to the starter and the contact group of the ignition switch must also be checked.
- In addition, you should check PCV valve(remove and shake it: the valve element inside should move freely), fuel pressure control, exhaust system - perhaps it is mechanically blocked by a foreign object or the catalysts are melted due to the operation of the car on low-quality fuel, as well as.

Travel enthusiasts know well how important it is to have a personal vehicle. Every car needs proper care. And the Mazda car in this sense is very demanding for car owners.
The cx model, on average, spends about 9.5 liters per 100 kilometers. This happens during the winter.
Distinctive design features of the machine:
- Solid style.
- Expressive silhouette.
- Impressive grille.
- Flashy headlights.
Unlike more dynamic and impetuous youth models, Mazda cx focuses on strength and stability.
At the same time, the car is not without originality. This obliges the fact that the Mazda cx is the first crossover of the sixth generation of the concern. Belonging to Japanese origin provides the machine with the high quality of every detail.
Mazda CX-5 operation - nothing is easier
It is brought into operation with a simple push of a button. Engine failure is extremely rare. The service department makes a minimum amount of repair work on this issue. 
The cabin contains many additional accessories and places for various small things. The car itself has increased functionality, which consists in the possibility of transporting large loads. The trunk of the car holds 465 liters. With the rear seat folded down, this volume increases to 1620 liters.
The winter safety of the vehicle is well thought out. It includes 6 pillows and special strong belts. In rear-end collisions, the head restraints are responsible for protection. For a low cost, specialists will make high-quality installation of lane departure warning devices and blind spot monitoring.
Winter Mazda CX-5 is not terrible
The winter season is a test of the strength of machines and their spare parts.. During this period, it is necessary to carefully comply with the requirements for storage, repair, maintenance and operation of the Mazda cx battery. In cold weather, the battery works much more intensively than in summer. 
Consequently, the discharge occurs an order of magnitude faster. The tuning of the car chassis is not unique, it takes place in the traditional way.
Not very large road defects will be hidden by a stiff suspension for a crossover. However, when hitting large pits, the shaking will be well felt. If repair of this component of the car is required, then it is preferable to turn to narrow specialists with sufficient experience.
For a certain audience, insufficient soundproofing of the car may not seem too pleasant. Here is a small list of parts that may be audible:
- At high speeds up to 110 kilometers per hour, you will hear how the wind blows on the outside mirrors.
- Winter tires also make noise.
- In addition, the motor, reaching high speeds, will immediately remind you of itself with a loud sound.
However, there are many motorists who love to get a feeling of euphoria from the growl of a car. Thus, the described vehicle, due to its expressiveness, is designed for more emotional owners.
If your Mazda cx needs repairs, it is quite easy to do it at any car service. Spare parts are produced in huge quantities, with their presence there are usually no problems.
Due to the presence of an active safety system in the car (as well as extensive experience in creating crossovers), the manufacturer's products are in excellent demand. To increase the reliability of protection, the vehicle equipment provides adaptive LED headlights. 
Designers have implemented a safe braking system. If suddenly there is a possibility of a car accident, then it is reduced by braking force. The convenience of driving is complemented by the presence of a special system synchronized with a smartphone, which provides control of various options.
It happens as follows: the picture that the camera captures appears on the screen of the smartphone. Thanks to this, when parking, you get additional opportunities.
With your own efforts, you can adjust the suspension with your own hands, as a result of which excess noise will be minimized. This opportunity is relevant for car owners who prefer a quiet ride.
There are hardly any vehicles without any flaws. cx, at times, also needs repair. But the number of such situations can be significantly reduced with proper operation and timely diagnosis.
Cx-5 is a reliable friend, it needs almost no repairs
The cx car has earned the trust and sympathy of drivers due to its excellent equipment and a wide range of features. In addition, an important advantage of cx is a reasonable ratio of quality and cost. Evidence of this is the increase in the number of cx buyers last year compared to previous periods.
Proper operation and a number of other factors will affect the smooth operation of your cx. But, unfortunately, no one will cancel the circumstances that cause the breakdown of cars. In this case, you will have to be prepared to repair it.
Various circumstances will affect the quality of the Mazda cx repair. In particular, this is the place where the car will be serviced. The cost of services also depends on who and where they provide them.
It is recommended to apply for repairs only to good professionals who have experience and use modern technology in their work. However, to reduce costs, you can do some of the repairs yourself.
Also, the price of service maintenance will fluctuate depending on the type and location of the breakdown, on the required part. Under favorable circumstances for you, the necessary spare part will be available from specialists.
The most common parts that wear out and require replacement or repair are:
- filters,
- brake pads,
- water pumps,
- starters,
- generators.
In some cases, you will need to replace the battery. If the cx is used improperly, it is likely that the middle parts of the power unit will become unusable.
The highest cost is the repair of the engine. Most often, it fails in the winter, because it is the sudden changes in temperature that negatively affect the serviceability of the transport.
Improper handling of the cx will result in serious costs in terms of time and money.
Thus, the least safe operation will guarantee the long-term use of the vehicle. And of course, when using your car, it is important not to forget about its mileage.
Our favorite model was obtained by the Japanese concern with almost no flaws, but they still exist. Which ones - see the following video:
