Maintenancea nd care

!Vehicles withagasolinee ngine: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 arapid charging device to start the
vehicle. If your vehicle's battery is discharged,
the engine can be jump-started from another
vehicle or from adonor battery using jumper
cables. For this purpose, the vehicle has ajump-
starting connection point in the engine com-
partment.
When jump-starting, observe the following
points:
RThe battery is not accessible in all vehicles. If
the other vehicle's battery is not accessible,
jump-start the vehicle using adonor battery
or ajump-startingd evice.
RYou may only jump-start the vehicle when the
engine and exhaust system are cold.
RDo not start the engine if the battery is frozen.
Let the battery thaw first.
RJump-starting may only be performed from
batteries with anominal voltage of 12 V.
ROnly use jumper cables that have asufficient
cross-section and insulated terminal clamps.
RIf the battery is fully discharged, attach the
battery of another vehicle for afew minutes
before attempting to start. This charges the
empty battery alittle.
RMake sure that the two vehicles do not touch.
Make sure that:
Rthe jumper cables are not damaged.
Rbare parts of the terminal clamps do not come
into contact with other metal parts while the
jumper cables are connected to the battery.
Rthe 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
XApply the parking brake.
XShift the transmission to position P.
XSwitch off all electrical consumers, e.g. audio
equipment, blower.
XTurn key to position 0in the ignition lock and
remove it.
XOpen the hood (Ypage 241).
Connecting the jumper cable
XPush contact protection cover :of the jump-
starting connection point backwards against
the spring force as far as it will go.
The jump-startingc onnection point is visible.
Terminal connecting plan
XRemove the cover from positive terminal =
of the donor vehicle's battery.
XConnect the positive terminal clamp of the
jumper cable to positive terminal =of the
donor vehicle's battery, and then to positive
terminal Aof the jump-startingc onnection
point.
XRun the donor vehicle's engine at idling
speed.
