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.
f Please see the chapter “BATTERY” on
Page 249.
f Please see the chapter “EMERGENCY UNLO-
CKING OF THE FRONT LUGGAGE COMPART-
MENT LID” on Page 248.
Note
f Do 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 short circuit, damage and explosion,
resulting in serious personal injury or death.
f Use only jumper cables of adequate diameter
cross-section and fitted with completely insu-
lated alligator clips.
f Follow all warnings and instructions of the
jumper cable manufacturer.
f When 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.
f The vehicles must not be in contact, otherwise
current might flow as soon as the positive ter-
minals are connected.
f The cable clamps must not be allowed to con-
tact each other when one end of the jumper ca-
bles are connected to a battery.
f Ensure that tools or conductive jewelery (rings,
chains, watch straps) do not come into contact
with the positive jumper cable or the positive
battery post.
f Improper hook-up of jumper cables can ruin
the alternator. Danger of caustic burns
from escaping acid.
f Do not lean over the battery.
Danger of gas explosion.
f Improper use of booster battery to start a
vehicle may cause an explosion, resulting in
serious personal injury or death.
f Keep sources of ignition away from the bat-
tery, e.g. open flame, burning cigarettes or
sparking due to cable contact or welding work.
f A discharged battery can freeze even at 23 °F/
–5 °C.
Before connecting jumper cables, a frozen
battery must be thawed out.

Practical Tips, Emergency Service
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 th e 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.
f Note
Before disconnecting the jumper cables, elec-
trical loads such as the heated rear window
and the heating fan blower should be switched
on (the vehicle’s lights must not be switched
on). This reduces voltage peaks which may oc-
cur when disconnecting the jumper cables.
With the engine running, remove both jumper
cables in reverse order.

Warning!
Risk of short circuit.
f Always switch off the relevant consumer when
changing bulbs.
Risk of serious personal injury or death.
The Bi-Xenon headlights are under high
voltage when installed.
f Be careful during all work in the area of the Bi-
Xenon headlights.
Risk of damage. Bulbs of a higher wattage
can damage the lamp housing.
f Only the bulbs shown in the chart may be used.
f New bulbs must be clean and free from oil,

Headlights
Caution!
Risk of damage to headlights due to exces-
sive temperatures and abrasion.
f To ensure optimum ventilation, do not cover
the gap between headlight and body
(e.g. “stone guards” or films).
f Use soapy water only to clean light lenses and
plastic headlight lenses.
In no case may chemical cleaners or other vol-
atile cleaning fluids be used.
f To prevent scratches, do not rub with a dry or merely moist cloth, tissue or insect sponges.
Removing headlights1. Unscrew plastic nut A.
Detach the side carpeting. 2. Remove rubber plug
B from the unlocking
opening.

3. Place socket wrench (tool kit) on the unlocking spindle.
The handle of the wrench should point horizon-
tally to the rear.
4. Turn socket wrench approx. 180° A. The
headlight is unlocked and pushed forward
slightly during this process.
5. Turn socket wrench ba ck until it is pointing
vertically downward B and leave in position.
6. The headlight is now unlocked and can be pulled forward out of the fender.
Installing1. Insert headlight into the guide rails and push
fully into the fender.
2. Push headlight to the rear and at the same time turn the socket wrench until it points
horizontally to the rear C.
The headlight locking device must perceptibly
and audibly engage.
3. Insert the rubber plug into the unlocking opening and secure the carpet.
Check the function of all lights.
