Vehicles with a gasoline engine: avoid
repeated and lengthy starting attempts. Oth-
erwise, the catalytic converter could be dam-
aged by non-combusted fuel.
If the indicator and warning lamps in the instru-
ment cluster do not light up at low tempera-
tures, the discharged battery may have frozen.
In this case you may neither charge the battery
nor jump-start the vehicle. The service life of a
thawed battery may be shorter. Start-up behav-
ior may deteriorate, in particular at low temper-
atures. Have the thawed battery checked at a
qualified specialist workshop.
Do not use a rapid charging device to start the
vehicle. If your vehicle's battery is discharged,
the engine can be jump-started from another
vehicle or from a donor battery using jumper
cables. For this purpose, the vehicle has a jump-
starting connection point in the engine com-
partment.
When jump-starting, observe the following
points:
R
The battery is not accessible in all vehicles. If
the other vehicle's battery is not accessible,
jump-start the vehicle using a donor battery
or a jump-starting device.
R
You may only jump-start the vehicle when the
engine and exhaust system are cold.
R
Do not start the engine if the battery is frozen.
Let the battery thaw first.
R
Jump-starting may only be performed from
batteries with a nominal voltage of 12 V.
R
Only use jumper cables that have a sufficient
cross-section and insulated terminal clamps.
R
If the battery is fully discharged, attach the
battery of another vehicle for a few minutes
before attempting to start. This charges the
empty battery a little.
R
Make sure that the two vehicles do not touch.
Make sure that:
R
the jumper cables are not damaged.
R
bare parts of the terminal clamps do not come
into contact with other metal parts while the
jumper cables are connected to the battery.
R
the jumper cables cannot come into contact
with parts such as the V-belt pulley or the fan.
These parts move when the engine is started
and while it is running.
Jumper cables and further information regarding
jump starting can be obtained at any qualified
specialist workshop.
Before connecting the jumper cables
X
Apply the parking brake.
X
Shift the transmission to position P.
X
Switch off all electrical consumers, e.g. audio
equipment, blower.
X
Turn key to position 0 in the ignition lock and
remove it.
X
Open the hood (

page 242).
Connecting the jumper cable
X
Push contact protection cover
:
of the jump-
starting connection point backwards against
the spring force as far as it will go.
The jump-starting connection point is visible.
Terminal connecting plan
X
Remove the cover from positive terminal
=
of the donor vehicle's battery.
X
Connect the positive terminal clamp of the
jumper cable to positive terminal
=
of the
donor vehicle's battery, and then to positive
terminal
A
of the jump-starting connection
point.
X
Run the donor vehicle's engine at idling
speed.
