If the engine does not start
Attention! If the engine does not start, do not attempt to start it while towing the vehicle. Doing so may result in an accident or other damage. Moreover, starting the engine by towing may overload the catalytic converter and cause a fire.
If the engine does not turn over with the starter or turns over very slowly
1. If the car is equipped with an automatic transmission, move the selector to the position «R» or «N» and apply the emergency brake.
2. Check the wire connections to the battery terminals to make sure they are clean and tight.
3. Turn on the interior lamp. If the lamp burns weakly or goes out when the starter is engaged, then the battery is discharged.
4. Check up tightness of connections of wires of a starter.
5. Do not start the engine by towing.
6. Check the fuel level in the tank.

7. Check the connections of all wires of the ignition system, coil and spark plugs. Reconnect disconnected or poorly connected connections (pic. 1.139).
8. Check the fuel line in the engine compartment.
Starting the engine from an external source
The battery used as an additional source must have a nominal voltage of 12 V.
To start a car with a discharged battery from an external source, follow the instructions below exactly.
Attention! The gas given off by the battery during engine start is highly explosive. Failure to follow these instructions could result in serious vehicle damage or personal injury. If you are not sure about the correct operation of this operation, seek qualified assistance. Car batteries contain hydrochloric acid. It is poisonous and corrosive.
1. If the secondary battery is installed in another vehicle, make sure the vehicles are not touching each other.
2. Turn off all unnecessary lighting and accessories on both vehicles.

3. Connect the connecting cables to the battery terminals in the order shown in Figure 1.140.
First, connect the end of one of the connecting wires to the positive (+) terminal of a discharged battery. Then connect the other end of this wire to the positive terminal (+) battery in another car (used as an additional source). After that, using another connecting wire, connect one end of it to the negative (–) battery terminal of another vehicle (used as an additional source). Then connect the other end of this wire to the engine block of the vehicle with the dead battery, in a location that is as far away from the battery as possible. Do not connect the connecting cable to moving parts of the engine.
4. Start the car engine with the battery being used as an auxiliary source and let the engine idle for a few minutes. This will ensure that the battery is fully charged. While starting the engine, keep the engine speed of the car, the battery of which is used as an additional current source, at the level of 2000 min-1.
5. Start the car using the operations for normal starting the engine. After the engine starts, do not remove the connecting wires and let the engine idle or at 2000 min-1 for a few minutes.
6. Carefully remove the connecting wires in the reverse order of their installation. Remove the connecting cable from the negative terminals first and then from the positive terminals.
If the engine is overheated
1. Pull off the road and stop your vehicle in a safe place.
2. Move the selector to position «R» («Parking») (Automatic transmission) or shift lever to neutral and apply the parking brake. If the air conditioner is running, turn it off.
3. If coolant is leaking from under the vehicle or steam is coming from under the hood, turn off the engine. Do not open the hood until coolant stops flowing from under the vehicle or steam stops coming out from under the hood. If there are no visible signs of a coolant leak, keep the engine running and check that the cooling system radiator fan is running. If it doesn't work, turn off the engine.
4. Check up presence of a belt of a drive of the pump of a cooling liquid. If it is in place, check its tension.
5. If the drive belt or coolant pump is faulty, or there is a coolant leak, stop the engine immediately and seek professional assistance.
Attention! Do not open the radiator cap while the engine is hot. Boiling coolant may be released.
6. If the cause of overheating is not found, wait until the engine coolant temperature returns to normal. If there is a coolant leak, carefully remove the radiator cap and add coolant to half the level mark on the expansion tank.
Attention! A severe drop in coolant level indicates a leak in the cooling system.
