The yellow warning
lamp remains on if the system is faulty or if
the pressure is too low in at least one tyre. In the event of a system
fault, the letters TPMS are displayed in the centre of the instrument
panel ⇒page 66, fig. 45 . If the tyre pressure drops rapidly, the
message ⇒page 66, fig. 46 will be shown on the central display
of the instrument panel. If the pressure loss is more gradual, the
message ⇒page 66, fig. 46 will be shown on the central display
of the instrument panel. This message does not show the tyre
affected. Should any of these warnings be displayed:
– Stop the engine.
– Check the tyres. Although the warning corresponds to just one tyre, you should also check the others.
– Correct the tyre pressure ⇒page 236.
For more detailed information on the tyre pressure monitoring system, please
refer to ⇒page 235.Cruise control system*
The indicator lamp
on the instrument panel lights up when the cruise
control system is operating.
Trailer indicators*
This indicator lamp flashes when the indicators are operating
while towing a caravan or trailer.The indicator lamp
flashes when the indicators are operated if a trailer is
correctly coupled to the vehicle.
Where a turn signal lamp does not work, either on the trailer or on the towing
vehicle, the indicator lamp will not flash.
Anti-lock brake system (ABS)
The warning lamp monitors the ABS and the integrated elec-
tronic 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
after 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 brake in the normal way (except that the ABS control func-
tion is out of action). Please take the vehicle to a specialist garage as soon as
possible. For further information on the ABS ⇒page 184.
If a malfunction should occur in the ABS, the ESP warning lamp will also light
up.

68Entire brake system fault
If the ABS warning lamp
lights up together with the brake warning lamp
⇒ page 70 (with the handbrake released), this indicates not only a fault
in the ABS function, but probably also a malfunction in the main brake system
as well ⇒.
The symbol
will light up in the instrument panel if a fault occurs in the
brake system . Please refer to ⇒page 77.
Electronic differential lock (EDL) fault
The EDL works in conjunction with the ABS. The ABS indicator lamp will light
up
to indicate an EDL fault. Please take the vehicle to a specialist garage
as soon as possible. For further information on the EDL ⇒page 185.WARNING
•Before opening the bonnet and checking the brake fluid level, observe
the warning information in ⇒page 221, “Work in the engine compart-
ment”.•If the brake warning lamp
should light up together with the ABS
warning lamp
, stop the vehicle immediately and check the brake fluid
level in the reservoir. If the fluid level has dropped below the "MIN" mark
you must not drive on otherwise there may be an increased accident risk.
Obtain technical assistance.
•If the brake fluid level is correct, the fault in the brake system may have
been caused by a fault in the ABS control function. As a result, the rear
wheels can lock relatively easily when braking. Under certain circum-
stances, the rear of the vehicle could suddenly sway from side to side, with
the subsequent danger of skidding. Drive carefully to the nearest specialist
garage and have the fault rectified.
Seat belt warning lamp*
The warning lamp acts as a reminder to the driver to fasten
the seat belt.After switching on the ignition, the warning lamp
will remain lit until the
driver and front passenger (if applicable) have fastened their seat belts.
When the vehicle has reached a certain speed, you will also hear a warning
signal and the warning light will flash.
For further information on the seat belts, see ⇒page 22.
Indicators and hazard warning lights
Depending on which turn signal is operated, either the left
or right
indi-
cator lamp flashes. Both indicator lamps will flash when the hazard warning
lights are switched on.
If one turn signal fails, the indicator lamp will start flashing twice as fast as
normal.
This does not apply when towing a trailer. Where a turn signal lamp does not
work, either on the trailer or on the towing vehicle, the indicator lamp will not
flash. For further information on the indicators, see ⇒page 122.
Electronic stabilisation programme
This warning lamp monitors the electronic stabilisation
program (ESP).The warning lamp
has the following functions:

•It will start flashing to indicate that ESP is counteracting an unstable
driving condition.•It lights up when the ignition is switched on for approx. 2 seconds while
the function is checked.•The warning lamp will light up if there is a malfunction in the ESP.•It will light up after the battery has been disconnected.•The warning lamp will light up if the ESP is switched off.•It will also come on if a fault should occur in the ABS because the ESP
operates in conjunction with the ABS.
If the ESP warning lamp lights up and stays on after the engine is started, this
may mean that the control system has temporarily switched off the ESP. In this
case the ESP can be reactivated by switching the ignition off and then on
again. After this the warning lamp should go out to show that the system is
fully functional.
The warning lamp will light up when the ignition is switched on if the battery
has been disconnected and then reconnected. It should go out again after
driving a short distance if the steering wheel is turned slightly.
For further information on the ESP, see ⇒page 185.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
switch off after the engine has started.
If the warning lamp lights up when you are driving, you can normally
continue as far as the nearest specialist garage. However, given that the
battery will be running down, any electrical consumption not absolutely vital
should be switched off.
Caution
If the coolant warning lamp

ately and switch off the engine. In this case the coolant pump is no longer
being driven, and there is a risk of engine damage.
Main beam headlights
The indicator lamp
lights up when the main beams are on or when the
headlight flasher is operated.
For further information on the main beam headlights, see ⇒page 122.
Engine management
This warning lamp monitors the engine management system
for petrol engines.The warning lamp
(Electronic Power Control) lights up while the function

the indicator lamp goes out the engine should be started straight away. When
the engine is warm, or at outside temperatures above +8°C, the indicator
lamp will only light up very briefly.
Note
•If the glow plug indicator lamp should start flashing while the vehicle is
moving, this indicates a fault in the engine management system. The engine
should be serviced without delay.•If the indicator lamp fails to light up when the ignition is switched on, this
can mean that the glow plug system is defective. The engine should be
serviced.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 warning lamp
flashes (and the handbrake is not applied), stop the
vehicle and check the brake fluid level ⇒ ⇒ page 230.
If a failure should occur in the ABS, the ABS warning lamp
will light up
together with the brake warning lamp

The warning lamp
also lights up when the handbrake is applied. In addi-
tion to this, the handbrake warning ⇒ page 76 switches on after driving for 3
seconds at a speed above 5 km/h.
WARNING
•Before opening the bonnet and checking the brake fluid level, observe
the warning information in ⇒page 221, “Work in the engine compart-
ment”.•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 and this may cause
an increased accident risk. Stop the vehicle and do not drive on. Obtain
technical 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. Under
