In case of an emergency, a jump start may be necessary to start a vehicle. In the case
of a jump start, proceed as follows:
1. Remove battery cover and all terminal covers.
2. Check the battery for the following errors:
– Signs of leaking electrolyte
– Loose terminals
– Bulging housing
3. Check if the recipient vehicle has the same on-board voltage and the same
ground polarity as the donor vehicle. The donor vehicle must have s 12 VDC
on-board voltage and an electrical system with negative ground.
4. Park the donor vehicle as close to the recipient vehicle as needed for easy
connection of the jumper cables to the batteries.
5. Shift to idle.
6. Activate parking brake.
7. Switch off any electrical accessories.
8. Turn ignition key to OFF position.
9. Disconnect al external devices such as e.g. mobile phones, navigation systems,
and radios from the on-board power supply in both vehicles.
WARNING
Leaking or bulging batteries indicate a frozen battery or a short circuit. When
detecting the condition of a battery, under no circumstance perform an exter-
nal start of the vehicle nor charge the battery. There is the risk of explosion.
CAUTION
If the on-board voltage and/or the ground polarity are not identical, this may
lead to serious electrical damage.
NOTE
Make sure that all switches on the recipient vehicle are switched off.
ATTENTION
If the electrical accessories are not disconnected form the on-board power
supply, this may lead to system damage due to voltage peaks during the
jump start.
NOTE
Some jumper cables do not differ in colour. In this case, the clamps and
cable ends are marked red and black.
