The electrolyte is very aggressive. Use protective gloves and goggles. Do not tilt the battery as electrolyte may spill out of the vents. If electrolyte gets into your eyes, immediately flush them with clean water for several minutes. After that, be sure to consult a doctor. If electrolyte comes into contact with skin or clothing, immediately neutralize the acid with alkaline soap and wash the affected area with plenty of clean water. If electrolyte is ingested by mistake, consult a doctor immediately.
When batteries are charged, an explosive mixture of gases is released.
When working with wires and electrical appliances, it is forbidden to use fire, sparking devices, open flammable light devices and smoking. Avoid sparking when handling wires and electrical devices. Never short the battery terminals directly - there is a great risk of injury due to strong sparks.
Before carrying out any work on the electrical system of the vehicle, disconnect «negative» battery wire. When replacing incandescent lamps, it is enough to turn off the corresponding switches.
When disconnecting the battery from the vehicle's electrical system, first disconnect «negative» wire, then «positive». When the engine is running, the battery must not be disconnected, otherwise the electronic devices of the electrical system will be damaged.
When installing a battery in a vehicle, you must first connect «positive» wire and then «negative».
To protect the battery case from UV radiation, do not store the battery in direct daylight.
Checking the electrolyte level
Pic. 2–30. Location of marks for checking the electrolyte level in the battery
The battery is virtually maintenance-free under normal vehicle operating conditions. At high ambient temperatures, it is recommended to check the electrolyte level in the battery from time to time. The electrolyte level should also be checked when the battery is being charged. It must always be between the MIN and MAX marks on the longitudinal sides of the battery (pic. 2–30).
When the electrolyte level drops, add distilled water to the appropriate jars up to the MAX mark. This must be done before the electrolyte level falls below the MIN·mark.
Do not fill the electrolyte above the required level, as it will flow out through the vent. This can damage the paintwork and corrosion of the body.
After topping up the electrolyte, tightly close the corresponding battery banks with stoppers.
Operation in winter conditions
In winter, the battery has a particularly heavy load. In addition, at low temperatures, the battery gives out when starting the engine only a part of the power that it has at a positive temperature. Therefore, it is recommended to check the battery before the start of the winter season and, if necessary, recharge it.
If the car is not used for several weeks in very cold weather, the battery should be removed and stored in a heated room so that it does not freeze and, as a result, does not collapse.
If the battery has been disconnected from the on-board network and reconnected to it
If the battery is disconnected from the on-board network:
- all information in the storage device of the on-board computer is erased;
- all information in the driver's seat position memory is erased;
- clocks with pointer indication stop, with digital indication - go astray;
- the factory-installed receiver is disabled;
- the automatic device for raising and lowering windows with electric windows does not work.
After connecting the battery to the on-board network, you must reset the clock with both an arrow and a digital display.
Then it is necessary to restore the functioning of the automatic device for raising and lowering the windows.
In addition, the driver's seat position memory must be loaded.
Factory installed radio can only be made operational by entering the appropriate code (see the Radio User's Guide in sect. 1).
Removing and installing the battery
Switch off the ignition.
Remove the right decorative side panel and trunk floor panel.
Disconnect the battery ground strap located in the floor panel.
Pic. 2–31. Elements for fastening and connecting the battery: 1 - negative terminal; 2 - positive terminal; 3 – a bolt of fastening of an arm; 4 - gas outlet hose
Remove negative terminal 1 (pic. 2–31) from the battery and move it to the side.
Disconnect the gas outlet hose 4 from the battery.
Unscrew bolt 3 and remove the battery mounting bracket.
Lift the battery by the handles and remove it from the vehicle.
Installation
Installation is carried out in the reverse order of removal, taking into account the following.
When installing the battery, do not pinch the hose designed to remove gases released during battery operation. A valve is located in the gas exhaust pipe, which protects the battery from backfire.
Secure the battery with the bracket and screw in the bracket fastening bolt, tightening it to 20 Nm.
Check that the battery is securely fastened, as otherwise its service life may be significantly reduced.
Connect the positive terminal to the battery first, then the negative terminal and secure them by tightening the fastening nuts to a torque of 5 Nm.
Turn on radio and enter the code into it.
Raise the windows with the power windows up to the stop. Then press all power window switches again for at least 1 second to the closed position to activate the power window control unit.
Set the time on the clock.
