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 qualified work-
shop as soon as possible. For further information on the EDL, see
⇒ page 186.
WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 221, Work in the engine com-
partment.
● 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, as there is a risk of accident. Obtain technical as-
sistance.
● 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 cir-
cumstances, the rear of the vehicle could suddenly sway from side to
side, with the subsequent danger of skidding. Drive carefully to the near-
est specialised workshop and have the fault repaired.
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 23.Turn signals and hazard warning lights
Depending on which turn signal is operated, either the left or right turn
signal lamp flashes. Both turn signal lamps will flash when the hazard warn-
ing lights are switched on.
If a 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 bulb does not
work, either on the trailer or on the towing vehicle, the turn signal bulb will
not flash. For further information on the turn signals, see ⇒ page 122.
Electronic Stability Programme
This warning lamp monitors the Electronic Stability Pro-
gramme (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
69
Cockpit
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 bat-
tery 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 186.
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 qualified workshop. However, given that the
battery will be running down, any electrical consumption not absolutely vi-
tal should be switched off.
CAUTION
If the coolant warning lamp in the instrument panel lights up as well as
the alternator waning lamp while driving ⇒ page 78, stop the vehicle im-
mediately and switch off the engine. In this case the coolant pump is no
longer working, 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 sys-
tem for petrol engines.
The warning lamp (Electronic Power Control) lights up while the function
is being checked.
Note
If the warning lamp lights up while the vehicle is moving, this indicates a
fault in the engine management system. The vehicle must be taken immedi-
ately to a qualified workshop to have the engine serviced.
Glow plug system
The indicator lamp lights up while the glow plugs are pre-
heating.
The indicator lamp lights up while the glow plugs are preheating. When
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
warning lamp will only light up very briefly.

Service reminder
The instrument panel controls the distance travelled every day. It calculates
the average of these distances travelled and activates the service reminder
sufficiently in advance.
The display reverts back to the standard display after about 5 seconds. The
remaining distance to the next service is updated every time the ignition is
switched on, until the service becomes due.
Service due
When a service is due, SERVICE! will appear in the display immediately after
you switch on the ignition. The display reverts back to the standard display
after about 5 seconds.
Resetting the display
The display is reset by the workshop after the service has been carried out.
The service interval will be set to a LongLife Service (flexible service inter-
val) or Inspection Service (fixed service interval), depending on which en-
gine oil is used. It is only possible to reset the display via the instrument
panel when an oil change is performed; in this case the display can only be
reset to a fixed service interval of 15 000 km. Proceed as follows:
● Switch the ignition off.
● Press the service button ⇒ fig. 52 1
and hold while switching on the
ignition. The display will show one of these messages: Service in ----- km or
Service!
● Now press and hold the reset button 2
until the display shows
Service
in ----- km --- days or Service!
The display switches out of the reset mode if you do not press the reset but-
ton within 5 seconds.
CAUTION
The system cannot calculate the figures for the service interval display if the
battery is disconnected from the vehicle, so no service reminder can be dis-
played during this time. Please remember that it is essential to service the
vehicle within the established time limits to prevent its deterioration and to
extend its useful life (particularly that of the engine). The period between
two services must never be longer than the time specified in the Mainte-
nance Programme, even if you only cover a low mileage during this time.
Note
● Do not reset the service indicator between services, otherwise the dis-
play will be incorrect.
● The information in the service indicator remains intact if the battery is
disconnected.
● The distance to the next service cannot be called up if the system has
detected a Priority 1 fault (red symbol).
Auto-check system Introduction
The auto-check system checks important components and vehicle systems.
These background checks are run constantly, as long as the ignition is
switched on.
A message is displayed on the instrument panel if a fault should occur or if
any maintenance or repairs are urgently required. This is accompanied by
an audible warning signal. Depending on the priority of the fault, a red or
yellow warning symbol lights up on the display.

Engine oil level correct
If the symbol flashes and the engine oil level is correct, obtain profes-
sional assistance. Do not drive on! Do not continue to run the engine, even
at idle speed .
Note
The oil pressure warning lamp is not an indicator for the oil level. The oil
level should therefore be checked regularly, preferably every time you fill
the tank.
