Practical Tips, Emergency Service
Removing the battery The required tool is in the tool kit.
The battery is located in the luggage compart-
ment under a black plastic lid.
Warning!
Risk of damage to alternator and electronic
control units.
fDo not disconnect the battery while the engine
is running.
This also applies to cars equipped with a bat-
tery main switch.
fNever drive the car with a disconnected bat-
tery.
Risk of caustic burns from escaping acid.
fKeep vent caps on to avoid spillage.
fDo not tilt the battery when removing and in-stalling it. 1. Switch off engine and all electrical loads.
2. Open turn-locks A.
Remove plastic lid.
3. Pull off central vent hose C.
Danger!
Risk of short circuit and explosion.
fImportant: disconnect the negative (–) ground wire first, and then the positive (+) cable.4. Unscrew fastening screw B.
5. Remove battery.

Emergency Starting with Jumper
Cables If the battery is discharged, e.g. in winter or after
the car has been parked for a long time, the bat-
tery of another car can be used for starting with
the help of jumper cables.
Make sure the voltage of both batteries is the
same. Both batteries must be 12 volt types.
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 con-
nected to the vehicle’s electrical system.
fPlease observe the chapter “BATTERY” on
Page 236.
fPlease observe the chapter “EMERGENCY UN-
LOCKING OF THE LUGGAGE COMPARTMENT
LID” on Page 235.
Note
fDo not try to start the car by pushing or tow-
ing. 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.
fUse only jumper cables of adequate diameter
cross-section and fitted with completely insu-
lated alligator clips.
fFollow all warnings and instructions of the
jumper cable manufacturer.
fWhen connecting jumper cables, 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.
fThe vehicles must not be in contact, otherwise
current might flow as soon as the positive ter-
minals are connected.
fThe cable clamps must not be allowed to con-
tact each other when one end of the jumper ca-
bles are connected to a battery.
fEnsure that tools or conductive jewelery (rings,
chains, watch straps) do not come into contact
with the positive jumper cable or the positive
battery post.
fImproper hook-up of jumper cables can ruin
the alternator. Danger of caustic burns.
fDo not lean over the battery.
Danger of gas explosion.
fImproper use of booster battery to start a
vehicle may cause an explosion, resulting in
severe personal injuries.
fKeep sources of ignition away from the bat-
tery, e.g. open flame, burning cigarettes or
sparking due to cable contact or welding work.
fA discharged battery can freeze even at
23°F/–5°C.
Before connecting jumper cables, a frozen bat-
tery must be thawed out.

Connect jumper cables in the following
sequence:
Always observe the sequence below:
1. Connect the positive lead (red) to the
positive terminal of the discharged battery
first, then connect it to the positive terminal of
the donor battery.
2. First connect the negative cable (black) to
the negative terminal of the donor battery, then
connect it to a suitable grounding point on the
vehicle with the discharged battery.
This grounding point must lie as far as possible
from the battery.
For example, a solid metal part or the engine
block are suitable grounding points.
If no suitable grounding points are to be found
on either vehicle, the negative cable must
carefully be connected directly to the negative
terminal of the battery.
If a suitable grounding point is to be found only
on the donor vehicle, the negative cable must
first be connected to the terminal of the
discharged battery, then to the grounding point
of the donor vehicle.
3. Run the engine of the donor car at a higher
speed.4. Start the engine.
An attempted start using jumper cables should
not last more than 15 seconds. Then allow a
waiting period of at least one minute.
Note
Before disconnecting the jumper cables, electrical
loads such as the heated rear window and the
heating fan blower should be switched on (the ve-
hicle’s lights must not be switched on). This reduc-
es voltage peaks which may occur when discon-
necting the jumper cables.
With the engine running, remove both jumper ca-
bles in reverse order.
