Emergency Starting With Jumper Cables

Emergency Starting with Jumper Cables

See other procedures regarding "Battery" and "Emergency Unlocking of the luggage compartment lids for supplemental procedures. Procedures

If the battery is discharged, e.g. in winter or after the car has been parked for a long time, the battery of another car can be used for starting with the help of jumper cables.
Make sure the voltage of both batteries is the same.
The capacity (Ampere hours, Ah) of the booster battery must not be substantially less than that of the discharged battery.
The discharged battery must be correctly connected to the vehicles electrical system.

IMPORTANT!
- Do not start the car by pushing or towing. Damage to the catalytic converters and other components of the car may result.

WARNING!
Risk of damage and serious personal injury due to short circuit.
- Use only jumper cable of adequate diameter cross-section and fitted with completely insulated alligator clips.
- Follow all warnings and instructions of the jumper cable manufacturer.
- When connecting jumper cable, make sure that they cannot get caught in any moving parts in the engine compartment.
The jumper cables must be long enough so that neither vehicles nor cables touch another.
- The vehicles must not be in contact, other-wise current might flow as soon as the positive terminals are connected.
- The cable clamps must not be allowed to contact each other when one end of the jumper cables are connected to a battery.
- Ensure that tools or conductive jewelry (rings, chains, watch straps) do not come into contact with live parts of the vehicle.
- Improper hook-up of jumper cables can ruin the alternator.

Danger of Caustic Burns
- Do not lean over the battery.

Danger of Gas Explosion
- Improper use of booster battery to start a vehicle may cause and explosion, resulting in sever personal injuries.
- Keep sources of ignition away from the battery, e.g. open flame, burning cigarettes or sparking due to cable contact or welding work.
- A discharged battery can freeze even at 14°F (-10°C).
Before connecting jumper cables, a frozen battery must be thawed out.

Connect Jumper Cables in the Following Sequence:

1. Check electrolyte level of each cell. If necessary, fill with distilled water to just above plates.

2. On a vehicle with a discharged battery: turn off all consumers and accessories, move the gear shift lever into the neutral position and set the parking brake.





3. Attach the positive cable first to the positive terminal 1 of the booster battery A, then to the positive terminal 2 of the discharged battery B.

4. Connect the negative cable first to the negative terminal 3 of the discharged battery B, then to a suitable earthing point 4 on the body of the vehicle with the booster battery. This earthing point must lie as far as possible from the battery.

5. Run the engine of the booster car at a higher speed.

6. Start the engine.
An attempted start using jumper cables should not last more than 15 seconds. Then allow a waiting period of at least on minute.

7. With the engine running, remove both jumper cables in the reverse order.
