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 124.
Electronic Stability Control (ESC)* /
There are two control lamps for the electronic stability con-
trol. The lamp provides information concerning the func-
tion and the provides information on the disconnection
status
Both lamps come on together when the ignition is switched on and should
go out after approx. 2 seconds, which is how long the function check lasts.
This programme includes the ABS, EDL and ASR. This also includes the
brake assistance system (BAS), automatic cleaning of the brake discs and
the trailer stability programme (TSP).
The warning lamp has the following functions:
● It flashes whilst driving when the ASR/ESC is activated.
● It will light up continuously if there is a fault in the ESC.
● As the ESC operates in conjunction with the ABS, it will also light up if a
fault should occur in the ABS. If the ESC warning lamp
lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESC.
In this case the ESC can be reactivated by switching the ignition off and
then on again. If the warning lamp goes out, this means the system is fully
functional.
The lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR is disconnected when pressing the switch.
Traction control system (ASR)* /
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating
There are two warning lamps for the traction control system: and . Both
lamps come on together when the ignition is switched on and should go out
after approx. 2 seconds, which is how long the function check lasts.
The lamp has the following function:
● It flashes when the ASR is working if the vehicle is moving.
If the system is deactivated or if it has any fault, the warning lamp will re-
main lit. The warning lamp will also light up if a fault should occur in the
ABS because the ASR operates in conjunction with the ABS. For further in-
formation, see ⇒ page 195
The lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR is disconnected when pressing the ASR OFF
switch.
By pressing it again, the ASR function is reactivated and the warning lamp
switched off.

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 81, 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 124.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 79.
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.
1)
Depending on the version of the model.

Cockpit
When the engine is warm, or at outside temperatures above +8°C, the warn-
ing lamp will only light up very briefly.
Note
● If the glow plug indicator lamp should start flashing while the vehicle is
moving, this indicates a fault in the engine management system. The en-
gine should be serviced without delay.
● If the indicator lamp fails to light up when the ignition is switched on,
this can mean that the glow plug system is defective. The engine should be
serviced.
Brake system
The warning lamp flashes when the handbrake is applied, or
if the brake fluid level is too low or if there is a fault in the
ABS system. If the warning lamp flashes (and the handbrake is not applied), stop the
vehicle and check the brake fluid level ⇒
⇒ page 244.
If a failure should occur in the ABS, the ABS warning lamp will light up
together with the brake warning lamp ⇒
.
Handbrake on
The warning lamp also lights up when the handbrake is applied. In addi-
tion to this, the handbrake warning ⇒ page 79 switches on after driving
for 3 seconds at a speed above 5 km/h.
WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 234, Work in the engine com-
partment.
● If the brake warning lamp does not go out, or if it lights up when driv-
ing, the brake fluid level in the reservoir is too low and this may cause an
increased accident risk. Stop the vehicle and 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.

CD, radio and telephone* display
Fig. 48 Display: addi-
tional radio information
If the radio is switched on and no Priority 2 faults are indicated by the auto-
check control, depending on the type of radio fitted, the display will show
the name or frequency of the selected radio station and complementary in-
formation, once the “OK” symbol has gone out.
When in CD mode*, the display will show the current track.
If you have a compatible telephone*, the phone book or telephone dialled
can also be seen on this display.
These displays appear in addition to the display on the radio itself. Outside temperature displayFig. 49 Display: Outside
temperature display
The outside temperature is shown in the display when the ignition is switch-
ed on ⇒ Fig. 49. In vehicles with an automatic gearbox, the display does not
appear until the driver has engaged a gear.
At temperatures below +5°C a snowflake symbol appears next to the tem-
perature display. This is to warn the driver to take extra care when there is a
risk of ice on the road. When the vehicle is stationary or travelling at very
low speeds, the temperature displayed may be slightly higher than the ac-
tual ambient temperature as a result of heat coming from the engine.
If the vehicle has an air conditioner and the digital display is changed over
to °F (degrees Fahrenheit), the outside temperature indicator automatically
changes over to °F ⇒ page 168.
WARNING
Do not rely on the outside temperature display as an ice warning. Please
bear in mind that there may be ice on the roads even at outside tempera-
tures of +5°C beware of ice patches.

Door and rear lid warning
Fig. 51 Display: Door
and rear lid warning
The door and rear lid warning symbol lights up if one or more of the doors,
or the bonnet or rear lid are not properly closed when the ignition is on. The
symbol also indicates which of these is not properly closed. The display in
the illustration ⇒ Fig. 51 shows that the driver door is open.
The corresponding part of the pictogram will flash if either the bonnet or
rear lid are open. The warning symbol goes out when the bonnet, rear lid
and all the doors are closed.
In vehicles with a driver information system and an onboard computer* the
door catches/rear lid warning symbol can be switched off by briefly press-
ing one of the control switches for the onboard computer ⇒ page 89. How-
ever, the warning symbol will appear again if any of the doors or the bonnet
or rear lid is opened or closed. Service indicator
This display reminds the driver when the next routine serv-
ice is due.

the instrument panel:
Service indicator
Displaying distance to next service
When you press the service button 1
briefly with the ignition switched on,
the display will show how far the vehicle can be driven before the next serv-
ice is due. This check can be carried out with the engine stopped or running
up to 5 km/h. Before the first 500 km and after the ignition cycle, the kilo-
metres and days before the service inspection are not displayed.
If the service button 1
is pressed before the first 500 km the following indi-
cation appears on screen:
Service in ----- km --- days
This is only valid for vehicles with “LongLife Service Intervals”*.

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.

COOLANTCoolant level too low / coolant tem-
perature too high⇒ page 81
OIL PRES- SUREEngine oil pressure too low⇒ page 81
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 244.

WARNING
● Before opening the bonnet and checking the brake fluid level, ob-
serve the warning information in ⇒ page 234, 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 239.
– Add more coolant if necessary ⇒ page 240.
– 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 engine off.
– Check the engine oil level ⇒ page 237.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒ page 238.

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 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 230.
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 237. Top up the oil at the next opportunity ⇒ page 238.
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 237.
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 203.
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.
