Instruments and warning/indicator lamps 18If the warning lamp does not go out, or if it lights up, flashes or
flickers when the vehicle is moving, this indicates a malfunction in
the system. This is also the case if the warning lamp does not light
up when the ignition is switched on.
WARNING
If a malfunction should occur, have the system checked immedi-
ately by a qualified workshop. If this is neglected, there is a risk
that the airbag system and/or belt tensioners may not be acti-
vated in an accident.Alternator

The warning lamp signals a fault in the alternator or in
the vehicle's electrical system.The warning lamp
 lights up when the ignition is switched on. It
should go out when the engine starts running.
If the warning lamp  lights up when you are driving, you can
normally continue as far as the nearest qualified workshop.
However, you should avoid using electrical equipment that is not
absolutely necessary because this will drain the battery.
Caution
If the coolant warning lamp
 in the instrument display lights up
as well while driving ⇒page 35, stop the vehicle immediately and
switch off the engine. In this case the coolant pump is no longer
being driven, and there is a risk of engine damage.
Seat belt warning lamp

The warning lamp acts as a reminder to fasten the seat
belts.After switching on the ignition, the warning lamp
 will remain lit
until the driver has fastened his seat belt. When the vehicle has
gathered speed you will also hear a warning chime.
For further information on the seat belts ⇒page 109.
Brake system

The warning lamp flashes if the brake fluid level is too low
or if there is a fault in the ABS system.If the warning lamp
 flashes (and the handbrake is not applied),
stop the vehicle and obtain professional assistance ⇒.
If a failure should occur in the ABS, the ABS warning lamp
 will
light up together with the brake warning lamp
 ⇒.
Handbrake applied
The warning lamp
 also lights up when the handbrake is applied.
If you drive by mistake with the handbrake still applied, you will hear
a warning buzzer.
WARNING
•
If the brake warning lamp does not go out, or if it lights up
when driving, the brake fluid level in the reservoir is too low – this
may cause an increased accident risk. Stop the vehicle and do not
drive on. You should obtain professional assistance.
•
If the brake warning lamp lights up together with the ABS
warning lamp, this can mean that the control function of the ABS
is out of action. As a result the rear wheels can lock relatively
easily when braking. This could cause the tail of the vehicle to skid

Technical data sideways. Drive carefully to the nearest qualified workshop and
have the fault rectified.
Anti-lock brake system (ABS)

The warning lamp monitors the ABS and the electronic
differential lock (EDL).The warning lamp
 lights up for a few seconds when the ignition
is switched on and while the engine is being started. The lamp goes
out again once the system has run through an automatic test
sequence.
There is a fault in the ABS if:
•
the warning lamp
 does not light up when the ignition is
switched on,
•
the warning lamp does not go out again after a few seconds,
•
the warning lamp lights up when the vehicle is moving.
The vehicle can still be braked in the normal way (except that the
ABS control function is out of action). Please take the vehicle to a
qualified workshop as soon as possible. For further information on
the ABS ⇒page 132.
If a fault occurs in the ABS, the ESP warning lamp will also light up.
Fault in the main brake system
If the ABS warning lamp
 lights up together with the brake
warning lamp
 ⇒page 35, this indicates a fault in the ABS func-
tion, and possibly a malfunction in the main brake system as well
⇒.
If there is a malfunction in the brake system the symbol
 will light
up in the instrument cluster. Please refer to ⇒page 18.Fault on the electronic differential lock (EDL)
The EDL works in conjunction with the ABS. If a malfunction should
occur in the EDL, this is indicated by the ABS warning lamp
.
Please take the vehicle to a qualified workshop as soon as possible.
For further information on the EDL ⇒page 132.
WARNING
•
If the brake warning lamp
 lights up together with the ABS
warning lamp
, the brake fluid level in the reservoir is too low
and this may cause an accident. Stop the vehicle and do not drive
on. You should obtain professional assistance.
•
If the brake fluid level is OK, the fault in the brake system may
have been caused by a failure of the ABS control function. As a
result the rear wheels can lock relatively easily when braking. This
could cause the tail of the vehicle to skid sideways. Drive carefully
to the nearest qualified workshop and have the fault rectified.

Fault in the brake system

The warning lamp flashes when the handbrake is applied,
or if the brake fluid level is too low or if there is a fault in
the ABS system.If the symbol

flashes in the display when the handbrake
is not applied, there is a fault in the brake system. One of the
following messages will appear in the display together with
the symbol:
Stop vehicle and check brake fluid level
Brake fault ! Drive carefully to nearest workshop
–Stop the vehicle.
– You should obtain professional assistance.
If the ABS fails, the ABS warning lamp
 will light up together with
the brake warning symbol
 ⇒.
Handbrake applied
The warning lamp
 also lights up when the handbrake is applied.
In addition to this, a warning buzzer will sound after driving for
3 seconds at a speed above 5 km/h.
WARNING
•
If the brake fluid level in the reservoir is too low, this could
result in an accident. Do not drive on. You should obtain profes-
sional assistance.
•
If the brake warning lamp lights up together with the ABS
warning lamp, this can mean that the control function of the ABS
is out of action. As a result the rear wheels can lock relatively
easily when braking. This could cause the tail of the vehicle to skid
sideways. Drive carefully to the nearest qualified workshop and
have the fault rectified.
Fault in the cooling system

Faults in the cooling system must be rectified immedi-
ately.If the
 symbol flashes in the display, this means that either
the coolant temperature is too high or the coolant level is
too low. The following message will appear in the display
together with the symbol:
Switch off engine, check coolant level
– Stop the vehicle.
– Switch off the engine.
– Check the coolant level ⇒page 160.
– Add more coolant if necessary ⇒page 160.
– Wait for the symbol to go out before driving on.
– Obtain professional assistance if necessary.
If the coolant level is correct, the overheating may be caused by a
malfunction of the radiator fan.
If the alternator warning lamp lights up as well ⇒page 18, it is
possible that the drive belt has broken.
WARNING
•
If your vehicle should break down for technical reasons, stop it
at a safe distance away from moving traffic, switch off the engine
and turn on the hazard warning lights ⇒page 56, “Hazard
warning lights ”.

Technical data Coming home function
When the system is activated and it is dark, the coming home func-
tion will illuminate the vehicle and its surroundings by switching on
the dipped headlights, rear lights, engine compartment lighting*
and number plate lights when the driver's door is opened.
The dipped headlights will stay on for about four minutes as long as
one of the doors or the luggage lid is open.
The dipped headlights stay on for about 30 seconds to light up the
area in front of the car after all the doors and the luggage lid have
been closed.
If required, you can set the time interval to between 0 and 60
seconds in the driver information system (Lights menu) ⇒page 24.
Leaving home function
The dipped headlights and the engine compartment lighting* are
switched on when the vehicle is unlocked with the
 button on the
remote control key if the leaving home function is activated in the
menu display ⇒page 24.
The dipped headlights and the engine compartment lighting*
switch off when the driver's door is opened. If the driver's door is not
opened, the dipped headlights and the engine compartment
lighting* will be switched off when the car automatically locks again
⇒page 41.
