Attention! Please also refer to chapter Engine electrical equipment
Attention! The intended service life of the battery is only achieved if it is always sufficiently charged. When using the car mainly for short distances or when parking for a long time, we recommend that you check the state of charge of the battery more often.
The battery is placed in a special niche on the right side of the luggage compartment.
Disconnecting the battery
Attention! If your car's radio is equipped with an anti-theft system, make sure you have entered the correct code before disconnecting the battery.
1. Do not loosen or remove the battery terminals while the engine is running. Otherwise, electronic components may be damaged (e.g. generator).
2. Turn off all electrical consumers.
3. First disconnect and remove the negative and then the positive terminal, use the key. Disconnecting the wire from the battery terminal with a wrench - sometimes, in cases where corrosion has destroyed the nut, special pliers are required for this procedure (always disconnect first and connect last the ground wire!)
4. After disconnecting the battery terminals, the electronic key in the ignition lock no longer turns, and the AT selector lever remains locked in the position «R».
Battery connection
1. Make sure all onboard electrical consumers are turned off.
2. First connect the positive and then the negative terminal.
3. After connecting the battery, it is necessary to carry out the following work:
- A) Clock setting (see chapter Manual).
- b) Introduction to the radio code memory.
- c) Realignment of the side windows (see chapter Manual).
- d) Re-adjusting the sliding and lifting sunroof (see chapter Manual).
- e) Re-alignment of the EPS system. To do this, turn the steering wheel from lock to lock with the engine running.
Check and care
Attention! Certain safety precautions must be taken when working with the battery.
Highly flammable hydrogen is always present in battery cells, so never approach a battery with a lit cigarette or other open flames.
Battery electrolyte is a solution of sulfuric acid, which can cause serious injury if splashed in the eyes or on exposed areas of the body.
In addition, the acid corrodes clothes and paints. When disconnecting the battery, always disconnect the earth cable first and connect it last!
Prepare the necessary tools.
Tools and Materials Needed for Battery Care
1 - Face shield / goggles - when brushing off traces of corrosion, particles of crystallized acid can easily get into the eyes
2 - Baking soda - an aqueous solution of baking soda can be used to neutralize corrosion
3 - Acid-free vaseline - a layer of vaseline applied to the battery terminals will help prevent corrosion
4 - Terminal/Wire Lug Stripper - This wire brush tool will remove all traces of corrosion from battery terminals and wire lugs
5 - Impregnated felt washers - installing such washers on each battery terminal directly under the wire lugs will help to avoid corrosion
6 - Puller - sometimes the wire ends are very difficult to remove from the battery terminals, even after completely loosening the nuts / bolts. This tool will help remove the tips vertically upwards without damage
7 - Terminal/wire stripper - another type of stripping tool, a slightly modified version of point 4 that performs the same functions
8 - Rubber gloves - another means of protection when working with a battery; remember that the battery contains acid!
1. Taking care of the battery is very important to avoid stopping on the road due to battery exhaustion. An appropriate tool is required to perform the maintenance procedure.
2. Before starting a maintenance procedure, always first turn off the engine and turn off all electrical appliances, then disconnect the ground cable from the battery.
Attention! If your car's radio is equipped with an anti-theft system, make sure you have entered the correct code before disconnecting the battery. 3. Typically, cars in this class are equipped with batteries that do not require special care. You can remove the lids of the jars and add distilled water. The latest models can be equipped with batteries that do not require maintenance at all, which are completely sealed.
4. Remove the caps and check the electrolyte level in each of the battery cells. It should be above the plates. Usually there is a level indicator on each bank. If the electrolyte level is below normal, add only distilled water and then close the lids of the jars.
Attention! Overfilling the jars can cause electrolyte to overflow during boost charging, causing corrosion and damage to components close to the battery! 5. If your vehicle's battery positive terminal and cable tie are equipped with a rubber protector, make sure it is not torn or damaged. It must completely cover the terminal.
6. It is necessary to periodically inspect the external condition of the battery for damage such as cracks in the case.
7. Check the tightness of the terminal clamps of the battery wires, providing a good electrical connection. Check each of the wires along the entire length for cracks and fraying of the insulation and wires. 8. When traces of corrosion are found (usually a loose white coating) disconnect the wires from the terminals, brush the pole terminals and wire terminals and reconnect the latter. Corrosion can be minimized by installing specially treated washers, available from auto parts stores, or by applying a coat of acid-free Vaseline or a suitable lubricant to the terminals and wire clamps after they are connected.
9. Make sure the battery tray is in good condition and the terminal clamp bolt is securely tightened. If the battery was removed from the pallet (refer to chapter Engine electrical equipment), describing the removal and installation procedure), make sure that there are no parts or other foreign objects on it during installation. When tightening the terminal clamp, do not overtighten its bolt.
10. Traces of corrosion from the sump, battery case and surrounding surfaces can be removed with an aqueous solution of baking soda. Apply the mixture with a small brush, let it sit and then rinse with plenty of clean water.
11. Corroded metal surfaces of the vehicle should be primed with a zinc-based primer and then painted.
Charger
Note. Manufacturers recommend removing the battery from the car to charge it, because. the gas released during this procedure may damage painted surfaces or the interior of the vehicle, depending on the location of the battery. Rapid charging with the battery wires connected can damage the vehicle's electrical system.
1. Remove all caps from battery jars (if they exist) and cover the openings with a clean rag to prevent electrolyte splashing. Disconnect the battery ground cable and connect the charger wires to its terminals (positive to positive, negative to negative), then plug in the charger. If it has a switch, make sure it is set to «12 V».
Attention! If your car's radio is equipped with an anti-theft system, make sure you have entered the correct code before disconnecting the battery.
2. If you are using a charger with more than two amps, check the battery regularly while charging to make sure it is not overheating. Using a slow charger, you can safely leave the battery charged overnight after checking regularly for the first two hours. Certain precautions may be required when charging maintenance-free batteries (e.g. using a very low current charger). This battery may have a warning label on it, but if not, consult the manufacturer's representative office or a workshop electrician.
3. If the battery cells have removable lids, check the electrolyte density with a hydrometer every hour during the last few hours of the charge cycle. Inexpensive hydrometers are available from auto parts stores - follow the instructions provided when using them. The battery can be considered charged if within two hours the density of its electrolyte does not change, and the electrolyte itself in the banks bubbles freely. The density of the electrolyte in individual banks should be almost the same. If this is not the case, then one or more cells of the battery have failed and should be replaced.
4. Some maintenance-free batteries have a built-in hydrometer at the top with a window - a color indicator of the battery charge level. Usually, a brightly colored window means that the battery is fully charged, while a dark color indicates that additional charging is needed. For more detailed information, see the battery manufacturer's instructions.
5. If the battery is sealed and does not have a built-in hydrometer, you can check the state of charge using a digital voltmeter connected to the battery terminals. A fully charged battery will show 12.6 or more volts.
