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 230.
If the ABS fails, the ABS warning lamp will light up together with the
brake system fault symbol ⇒

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 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 engine off.
– Check the coolant level ⇒ page 226.
– Add more coolant if necessary ⇒ page 227.
– 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 69, 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 engine off.
– Check the engine oil level ⇒ page 224.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒ page 225.

Cockpit
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.

Safety FirstOperating InstructionsPractical TipsTechnical Specifications
80Cockpit
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 217.
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 qualified 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 224. Top up the oil at the next opportunity ⇒ page 225.
Engine oil sensor defective*
If the symbol lights up, take the vehicle to a qualified 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 224.
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 2000 rpm. The increase in temper-
ature 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 qualified workshop to repair the fault.
For further information on the diesel particulate filter, see ⇒ page 193.
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.

Bulb monitor
The bulb monitor checks whether the lights on the vehicle
are working.
If a defective bulb is detected, or if one of the lights has failed for any rea-
son, the bulb monitor symbol will appear in the display together with an
additional message (which goes out after 5 seconds). For instance, if the
rear left turn signal is not working, the display in the instrument panel will
show the following message:
Left rear turn signal
The message disappears after 5 seconds. Press the CHECK button briefly if
you wish to call up the message again.
If the display indicates that one of the lights is not working, this can have a
number of causes:
● Bulb failure ⇒ page 258.
● A “blown” fuse ⇒ page 256, Changing fuses.
● Faulty electrical wiring.
It is not necessary to have lamps replaced in a specialised workshop, how-
ever the use of Xenon lamps is recommended.
LED lamps
If any of the LED (Light Emitting Diode) functions fail, the complete lamp
should be replaced.
The failure of the lamp is only shown when the LED function goes out com-
pletely. Sometimes, a LED will stop working, without displaying the warning
as the function continues to operate.WARNING
● Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
● The high voltage element of gas discharge bulbs* (xenon light) must
be handled correctly. Otherwise, there is a risk of death.
Speed warning* Introduction
The speed warning function can help prevent you exceeding
a particular pre-set maximum speed.
Fig. 56 Display: Speed
warning function
The speed warning function will warn the driver if a pre-set maximum speed
is exceeded. The system gives an warning buzzer signal if the set speed is
83
Cockpit
exceeded by about 10 km/h. A warning symbol will also appear in the dis-
play ⇒ fig. 56.
The speed warning function has two different warning speeds, which oper-
ate independently and serve slightly different purposes:
Speed limit warning 1
With speed limit warning 1, the maximum speed can be changed while driv-
ing. The speed limit that has been set remains stored until the ignition is
switched off, or until it is changed or cleared.
The warning symbol for speed limit warning 1 ⇒ fig. 56 will appear in the
display if you exceed the pre-set speed. It goes out again if the speed is re-
duced below the set speed limit.
The symbol also goes out if the speed is increased to more than about 40
km/h above the set speed for at least 10 seconds. However, this does not
cancel the speed limit that was originally set.
Setting speed limit warning 1 ⇒ page 83.
Speed limit warning 2
With speed limit warning 2, the speed limit can only be changed or cleared
when the ignition is switched off. You are recommended to store this speed
limit warning if you always wish to be reminded of a particular speed limit.
This could be when driving in countries with general speed limits, or if a
particular speed should not be exceeded when winter tyres are fitted etc.
The speed limit warning symbol for speed warning 2 will appear in the
display if you exceed the pre-set speed. Unlike speed limit warning 1, the
warning symbol only goes out once the road speed has dropped below the
set value again.
Setting speed limit warning 2 ⇒ page 84.
Note
Please bear in mind that, even with the speed warning function, it is still im-
portant to keep a eye on the vehicle's speed with the speedometer and to
observe the legal speed limits.
Setting speed limit warning 1
Use the CHECK button to set speed limit warning 1.

Cockpit
Onboard computer Introduction
The onboard computer provides you with useful information
during a journey, including average and current fuel con-
sumption, average speed, distance to empty, driving time
and distance covered.
Fig. 59 Onboard com-
puter: memory 1
Press RESET button B
⇒ fig. 60 to switch back and forward between on-
board computer functions 1 and 2.
The numbers in the display ⇒ fig. 59 indicate which of the two memories is
currently in use. A 1 means that the display is showing the information in
the single journey memory (onboard computer 1). A 2 means that the dis-
play is showing the information in the total journey memory (onboard com-
puter 2). Single-journey memory (onboard computer 1)
The single-journey memory processes the information on a journey from the
time the ignition is switched on until it is switched off. If the journey is re-
sumed within two hours after the ignition is switched off, the new figures
are automatically included in the calculation. If the journey is interrupted for
more than two hours the stored information is automatically erased when
you resume your journey.
Total-journey memory (onboard computer 2)
Unlike the single-journey memory, the total-journey memory is not erased
automatically. Hence, you can determine the period for which you wish the
onboard computer to supply figures.
Distance to empty
The estimated distance to empty is displayed in km. The distance to empty
is displayed in increments of 10 km.
Average fuel consumption
This mode shows the average fuel consumption since the memory was last
cancelled in litres/100 km.
Instantaneous fuel consumption
The display shows the instantaneous fuel consumption in litres/100 km.
When the vehicle is stationary, the computer will display the last value in
the memory.
Average speed
This mode shows the average speed driven since the memory was last can-
celled (in km/h).
Driving time
This display shows the period of time which has elapsed since the memory
was last cancelled. The longest possible period it can cover is 999 hours
and 59 minutes.
