When your battery is discharged you can
use two jumper cables to start your vehicle
with power from the battery in a second
vehicle. You can also use the same method
to help start another vehicle.Use only
jumper cables with fully-insulated clamp
handles.
To avoid the risk of potentially fatal
injury, always avoid all contact with
electrical components while the engine is
running. Carefully adhere to the following
sequence, both to prevent damage to one
or both vehicles, and to guard against pos-
sible personal injuries.<
Preparing
1.Check whether the battery of the other
vehicle has a voltage of 12 Volts and
approximately the same capacitance in
Ah. This information can be found on
the battery
2.Switch off the engine of the support
vehicle
3.Switch off any consumer units in both
vehicles.
There must not be any contact
between the bodies of the two vehi-
cles, as otherwise there is a danger of short
circuits.<

always observe this sequence when
connecting jumper cables.<
