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 specialised workshop. 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 in the instrument panel lights up as well as
the alternator waning lamp while driving ⇒ page 79, 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.Handbrake
This lamp lights up when the handbrake is applied.
If you drive faster than 5 km/h with the handbrake on, the following mes-
sage will appear on the instrument panel display 1)
: HANDBRAKE ON. You will
also hear an acoustic warning signal ⇒ page 77.
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 specialised workshop to have the engine serviced.
Glow plug system
The control lamp lights up while the glow plugs are preheat-
ing the diesel engine. The indicator lamp lights up while the glow plugs are preheating. When
the indicator lamp goes out the engine should be started straight away.

Depending on the version of the model.

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 specialised workshop after the service has been
carried out. The service interval will be set to a LongLife Service (flexible
service interval) or Inspection Service (fixed service interval), depending on
which engine oil is used. It is only possible to reset the display via the in-
strument 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 fol-
lows:
● 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.
80Cockpit
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.
Yellow symbols
A yellow symbol indicates a warning.

Photosensor/rain sensor faulty
Automatic headlights / automatic wipers faulty
If the symbol lights up, this means that the photosensor/rain sensor is
not working. For safety reasons, the dipped beam headlights will then be
switched on permanently when the light switch is set to the AUTO position.
However, you can still switch the lights on and off in the normal way with
the light switch. If the rain sensor is faulty, the functions operated via the
windscreen wiper lever will still be available. You should have the photosen-
sor/rain sensor checked by a specialised workshop as soon as possible.
Worn brake pads
If the symbol lights up, have the front brake pads (and, for safety rea-
sons, the rear pads as well) inspected by a specialised workshop.
Speed warning 1
If the symbol lights up, this means you are exceeding the speed that has
been pre-set with the speed warning function. You should reduce your
speed accordingly ⇒ page 83.
Headlight range control faulty
This symbol indicates a malfunction in the dynamic headlight range con-
trol. Take the vehicle to a specialised workshop to have the dynamic head-
light range control function repaired. Adaptive headlights* faulty
Adaptive headlights faulty
This symbol indicates that the adaptive headlight system is faulty. Take
the vehicle to a specialised workshop to have the headlights or the adap-
tive headlight control unit repaired.
Washer fluid level low
If the symbol lights up, top up the fluid for the windscreen washer and
headlight washer system* ⇒ page 234.
Speed warning 2
If the symbol lights up, this means you are exceeding the speed that has
been pre-set. You should reduce your speed accordingly ⇒ page 83.
Battery voltage too high or too low
If the symbol lights up, take the vehicle to a specialised workshop and
have the following items checked:
● Poly V-belt
● Battery condition
It is also advisable to check whether the alternator warning lamp has come
on ⇒ page 70.

Driving time warning
After 2 hours of continuous driving, the display automatically switches over
to the driving time display of 2:00. At the same time the driving time display
starts flashing. This is to remind the driver to take a break.
The driving time warning can be switched off by briefly pressing the func-
tion selector switch or the Reset
button ⇒ Fig. 60.
If you continue driving or take a break for less than 10 minutes, the driving
time warning will switch on once again when the total driving time is 4:00
hours, 6:00 hours, etc. However, if you take a break for more than 10 mi-
nutes, the driving time warning clock will be erased.
Distance covered
This display shows the distance you have covered since the memory was
last cancelled. The longest possible distance which can be recorded is
9999.9 km.
Note
● The displays for fuel consumption (average and instantaneous), dis-
tance to empty and speed are shown in metric units.
● The information in the memory is lost if the battery is disconnected. Operation
