The CHECK
button has the following functions:
Activating the digital clock and the odometer
When the ignition is switched off, the odometer and the digital clock with
date display can be enabled for a few seconds by pressing the CHECK
but-
ton ⇒ Fig. 44.
Starting check procedure (auto-check control)
The auto-check control ⇒ page 78 checks important components and ve-
hicle systems. These background checks are run constantly, as long as the
ignition is switched on.
You can start the “check procedure” manually by pressing the CHECK
button
with the ignition switched on. This function check can be started with the
engine either stationary or running, but not at road speeds above 5 km/h.
Calling up driver messages
If a Priority 1 symbol flashes in the display ⇒ page 78, or if the bulb moni-
tor detects a failure of one of the lights ⇒ page 85, the relevant driver in- formation can be called up again by briefly pressing the
CHECK
button. For
example:
Switch off engine, check oil level
The message will disappear from the display after about 5 seconds.
Setting the speed warning

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. 53 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.
79
Cockpit
The red symbol indicates danger, whereas the yellow one represents a
warning. Additional messages for the driver may be shown with the red or
yellow symbols.
Driver messages
Additional messages for the driver are displayed together
with the warning symbols on the instrument panel.

el: CHECK button
Driver messages and red symbols
If a red warning symbol appears on the display, you can press the CHECK
button ⇒ Fig. 54 to call up an additional driver message.
For example: in the event of an oil pressure malfunction, the oil pressure
symbol
will appear in the display. If you now press the CHECK
button,
the following message will appear in the display:
Switch off engine, check oil level The message will disappear from the display after about 5 seconds. If re-
quired, the message can be called up again by briefly pressing the
CHECK
button.
Driver messages and yellow symbols
If a yellow warning symbol appears in the display, it will automatically be
accompanied by the corresponding driver message.
For example, the symbol
is displayed to indicate that the windscreen
washer fluid level is low. In addition, the following message will appear:
Top up washer fluid
The message will disappear after a few seconds. If required, the message
can be called up again by briefly pressing the CHECK
button.
Note
● The messages handbrake on and when stationary apply footbrake to se-
lect gear cannot be called up a second time. They will remain in the display
until the handbrake is released or until a gear is selected.
Handbrake warning
– Release the handbrake.
If you drive by mistake with the handbrake still applied, you will hear a
warning buzzer and the display will show the message: Handbrake on
The handbrake warning switches on after driving for 3 seconds at speeds
above 5 km/h.

The red symbols are used to indicate a Priority 1 fault (serious malfunction). A red symbol is accompanied by
three warning chimes. The symbols will
keep flashing until the faults are corrected. If several Priority 1 faults are de-
tected at the same time, the symbols are displayed one after the other for
about 2 seconds.
Fault in the brake system
A fault in the brake system should be repaired as soon as
possible.
If the symbol flashes in the display, there is a fault in the brake
system. One of the following messages will appear in the display
together with the symbol:
Stop vehicle, check brake fluid and hydraulic fluid levels
Warning! Fault in brake system (ABS) Take vehicle to workshop
– Stop the vehicle.
– Check the brake fluid level ⇒ page 246.
If the ABS fails, the ABS control lamp will light up together with the brake
system fault symbol ⇒

Cockpit
WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 235, Work in the engine com-
partment.
● If the brake fluid level in the reservoir is too low, this could result in
an accident. Do not drive on! Obtain technical assistance.
● If the brake warning lamp lights up together with the ABS warning
lamp, this can mean that there is a fault in the ABS control function. As a
result, the rear wheels can lock relatively easily when braking. Under cer-
tain circumstances, the rear of the vehicle could suddenly sway from side
to side, with the subsequent danger of skidding. Drive carefully to the
nearest specialised workshop and have the fault repaired.
Fault in the cooling system
Faults in the cooling system must be repaired immediately.
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 and check coolant level
– Stop the vehicle.
– Switch the ignition off.
– Check the coolant level ⇒ page 241.
– Add more coolant if necessary ⇒ page 242.
– 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 malfunc-
tion of the radiator fan.
If the alternator warning lamp lights up as well ⇒ page 72, it is possible that
the drive belt has broken.
CAUTION
Do not drive on if the symbol has come on to indicate a fault in the cool-
ing system, otherwise there is a risk of engine damage.
Engine oil pressure too low
If the engine oil pressure is too low the fault must be re-
paired immediately.
If the symbol flashes in the display, the oil pressure is too low.
The following message will appear in the display together with the
symbol:
Switch off engine, check oil level
– Stop the vehicle.
– Switch the ignition off.
– Check the engine oil level ⇒ page 239.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒ page 240.

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.

Cockpit
Yellow symbols are used to indicate a Priority 2 fault (warning).
Yellow symbols are accompanied by one warning buzzer. The function indi-
cated should be checked as soon as possible. If several Priority 2 faults are
detected at the same time, the symbols are displayed one after the other for
about 2 seconds at a time.
Brake light failure
This warning light will appear on the upper part of the display if any of the
brake lights has failed. A text message in the central part of the display indi-
cates which brake light has failed (left or right).
Fuel level low
When this symbol comes on for the first time, there are about 8 to 10 li-
tres of fuel left in the tank. You should fill up as soon as possible
⇒ page 232.
Engine speed governing
Max. engine speed XXXX rpm
There is a fault in the engine management. In addition, the warning lamp
on the instrument panel will light up. The engine speed will be governed to
the speed displayed in the driver information system. Please ensure that
the engine speed does not exceed the speed shown (for example, when
changing down a gear).
Take the vehicle to a specialised workshop immediately to have the fault re-
paired. Checking the engine oil level
If the symbol lights up, please check the engine oil level as soon as pos-
sible ⇒ page 239. Top up the oil at the next opportunity ⇒ page 240.
Engine oil sensor defective*
If the symbol lights up, take the vehicle to a specialised workshop and
have the oil level sensor checked. Until then it is advisable to check the oil
level every time you fill up with fuel ⇒ page 239.
Diesel particulate filter obstructed
If the symbol lights up, you can contribute towards automatic filter
cleaning by driving in the right manner. To do this, drive about 15 minutes
in 4th or 5th gear (automatic gearbox: S gear range) at a speed of 60 km/h,
with the engine running at approximately 2,000 rpm. The increase in tem-
perature will burn off any soot in the filter. When cleaning is successful, the
symbol switches off.
If the symbol does not turn off, or the three lamps turn on (particulate
filter , emission control system fault and heaters ), take the vehicle
to a specialised workshop to repair the fault.
For further information on the diesel particulate filter, see ⇒ page 204.
WARNING
It is essential that you adjust your speed to suit the weather, road, ter-
rain and traffic conditions. The recommended driving speed must never
lead to the driver disregarding the traffic regulations.
