WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 227, 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 232.
– Add more coolant if necessary ⇒ page 233.
– 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 70, 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 230.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒ page 231.

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 223.
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 230. Top up the oil at the next opportunity ⇒ page 231.
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 230.
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 specialised workshop to repair the fault.
For further information on the diesel particulate filter, see ⇒ page 196.
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.

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.

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 264.
● A blown fuse ⇒ page 262, 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.

to lock the vehicle without activating the anti-theft security system.
To do so, turn the key in the driver door twice in quick succession to posi-
tion B
⇒ Fig. 70.
WARNING
Do not leave anyone (especially children) in the vehicle if it is locked from
the outside and the anti-theft security system is enabled, as the doors
and windows cannot then be opened from the inside. Locked doors could
delay assistance in an emergency, potentially putting lives at risk.
CAUTION
If the driver door is locked using the key while open, the vehicle will be au-
tomatically immobilised and the alarm triggered.
Note
● Please note that when the vehicle is locked without activating the anti-
theft mechanism, the anti-theft alarm* remains operative. You should there-
fore switch off the interior monitoring* before locking the vehicle, as other-
wise the alarm* could be triggered unintentionally.
● The driver door cannot be locked using the central locking system when
it is still open. The door must be locked separately after it has been closed.
