Warning! For safety reasons, when starting the engine from an external source, please follow the starting procedure described below. Otherwise, a fire or explosion may occur, resulting in damage to both vehicles.
Bring the cars next to each other at a distance that allows the connection of connecting cables, but excludes the contact of cars. If vehicles are touching, unwanted grounding may occur. In this case, you will not be able to start the engine of your car, and the electrical systems of both cars may also be damaged.
Attention! Check another car. It must be equipped with a battery with a nominal voltage of 12 V. If the voltage of the other battery differs from 12 V, the connection may damage the electrical equipment of both vehicles.
Moving vehicles can cause injury. Set the parking brake on both vehicles. Install the automatic transmission selector lever (by car with automatic transmission) into position «R» («Parking») or gear lever (in a car with a manual transmission) to neutral «N». Switch off the ignition.
Warning! First of all, turn off the ignition on both cars. Make sure wires and clothing do not get caught in fan blades or drive belts, otherwise injury may result.
Note. Turn off all lights, heater and other electrical appliances. This will prevent sparks and reduce the discharge of both batteries.
Check that the battery electrolyte level is correct.
Connect the end of one of the connecting wires to the positive (+) terminal of the discharged battery, and the other end of this wire to the positive terminal (+) battery in another car (used as an additional source).
Connect the end of the other connecting wire to the negative (–) battery terminal of another vehicle (used as an additional source), and the other end of this wire to the engine block of a car with a dead battery at a point that is as far as possible from the battery.
Note. Remove the battery protective cover before connecting the cable to the positive terminal.
Attention! Strictly observe the following sequence of wire connection operations: 1–2–3–4.
Make sure the clamp «crocodile» 4 (see fig.) securely fixed in place. If the connection is made directly to the negative battery terminal, it may cause flammable gases emitted from the battery to cause fire and explosion.
Do not connect positive (+) wire to negative (–) terminal. This may generate a spark and cause the battery to explode.
Use connecting wires that match (according to the cross section of the wire and insulation) both batteries. Otherwise, the wires may melt.
Before using the connecting wires, check if they are damaged or corroded.
Start the vehicle with the battery being used as a backup and let the engine idle for a few minutes, then start the vehicle with the dead battery.
Attention! Always maintain the engine speed of the car, the battery of which is used as an additional source of power, so that it does not stall.
After the engine is started, disconnect the connecting wires in the reverse order of their connection.
Warning! Charging a battery installed in a vehicle may cause a fire, explosion, or damage to the vehicle. If it is absolutely necessary to charge the battery without removing it from the vehicle, disconnect the cable from the negative battery terminal.
Warning! To prevent an explosion, keep sparks, open flames, and smoking away from the battery.
Ensure good ventilation when charging or handling the battery in an enclosed area.
Before charging the battery, unscrew all the lids of its cans.
Battery electrolyte is a sulfuric acid solution that is corrosive. If the electrolyte gets on your hands, eyes, clothing, etc. or on the painted surface of the car, they must be washed immediately with plenty of water. If electrolyte gets into your eyes, rinse immediately with water and seek medical attention.
If the engine runs unstable after replacing the battery
If the engine becomes unstable after replacing the battery, perform the ECM learning procedure as described below.
1. Stop the car in a safe place.
2. Place the shift lever in neutral «N». Stop the engine.
3. Start the engine again.
4. Turn off the air conditioning system.
5. Warm up the engine until the pointer of the coolant temperature gauge is approximately in the middle of the scale.
6. Stop and restart the engine.
7. Let the engine idle for approximately 10 minutes.
8. The training procedure can be considered completed after the stabilization of the idle speed.
Note. If the engine continues to run unstable after completing the ECM learning procedure, have the vehicle checked by an authorized Mitsubishi dealer.
