Airbag system
that the airbag system can only help to protect you if you are wearing your
seat belt and wearing it properly.
Remember too that airbags will deploy only once and only in certain kinds
of accidents - your seat belts are always there to offer protection in those
accidents in which airbags are not supposed to deploy or when they have
already deployed, for example when your vehicle strikes or is struck by an-
other after the first collision.
This is just one of the reasons why an airbag is not a substitute for the seat
belt. The airbag system works most effectively when used with the seat
belts. Therefore, always wear your seat belts correctly.
It is important to remember that while the airbag system is designed to re-
duce the possibility of serious injuries, other injuries, for example, swelling,
bruising, and minor abrasions can also be associated with airbags.
The knee airbag system basically consists of:
● The electronic control module
● One inflatable airbag (airbag and gas generator) for the driver
● An airbag indicator light on the instrument panel
The knee airbag system will not be triggered:
● if the ignition is switched off
● in frontal collisions when the deceleration measured by the control unit
is too low
● in side collisions
● in rear-end collisions
● in rollovers
● in the event of a system malfunction (hazard warning lights/turn signals
illuminated) ⇒ page 67.
WARNING
● Seat belts and the airbag system can only provide protection when
occupants are in the proper seating position.
● If the airbag indicator light comes on when the vehicle is being used,
have the system inspected immediately by your Technical Service. The
airbag may not work properly when the vehicle acceleration in a side col-
lision is high enough to deploy the airbag. See also ⇒ page 67.

How knee airbags work
The risk of injury to the leg area is reduced by fully deployed
knee airbags.
Fig. 23 Inflated airbags
protect in a frontal colli-
sion.
The knee airbag system has been designed so that the airbag for the driver
is deployed in certain but not all frontal collisions.
If the front airbag deploys, the knee airbag also deploys in severe frontal
collisions. 

Coolant temperature gauge
Fig. 39 Engine coolant
temperature gauge
The coolant temperature gauge ⇒ Fig. 39 only works when the ignition is
switched on. In order to avoid engine damage, please read the following
notes for the different temperature ranges.
Cold area A
If the needle is still on the left of the dial, this indicates that the engine has
not yet reached operating temperature. Avoid high revs and heavy accelera-
tion and do not make the engine work hard.
Normal area B
In normal operations, the needle will settle somewhere in the centre of the
dial once the engine has reached running temperature. The temperature
may also rise when the engine is working hard, especially at high outside8
910
temperatures. This is no cause for concern, provided the warning lamp

does not light up in the instrument panel.
Warning area C
If the symbol
 flashes in the display, this means that either the coolant
temperature is too high or the coolant level is too low ⇒ page 81.
WARNING
● Before opening the bonnet and checking the coolant level, observe
the warning information ⇒ page 235.
● Never open the bonnet when steam or coolant is being released from
it. This could lead to burns. Wait until you can no longer see or hear es-
caping steam or coolant.
CAUTION
Accessories in front of the air inlet reduce the cooling effect of the coolant.
At high outside temperatures and high engine loads, there is a risk of the
engine overheating. 

72Cockpit
Alternator 
The warning lamp signals a fault in the alternator or in the
vehicle's electrical system.
The control lamp  lights up when the ignition is switched on. It should
switch off after the engine has started.
The alternator is disconnected at very low temperatures and when the en-
gine is cold in order to facilitate starting.
Depending on the external temperature, the warning lamp  might remain
on for up to 5 seconds after the engine has been started. This does not
therefore indicate a fault.
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 (4 mph) with the handbrake on, the following
message 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 control 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 control 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.

73
Cockpit
When the engine is warm, or at outside temperatures above +8 °C, the
warning 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 control lamp  flashes (and the handbrake is not applied), stop the
vehicle and check the brake fluid level ⇒ 
⇒ page 246.
If a failure should occur in the ABS, the ABS control lamp  will light up
together with the brake control lamp  ⇒ 
.
Handbrake on
The control 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 235, 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.

Driver information system
General notes
The driver information system in the instrument panel
shows the status of various on-board systems at a glance.
Fig. 48 Cockpit: Digital
instrument panel display
The display for the driver information system is in the centre of the instru-
ment panel.
The system runs a check on certain components and functions when the ig-
nition is switched on and while the vehicle is moving. The DIS system gives
an audible warning if a fault should occur or if servicing is required, and a
red or yellow warning symbol (in some cases with a corresponding driver
message) appears in the instrument panel display.
The driver is informed on the audio system.
The driver information system includes the following functions:

Door and rear lid warning
Fig. 52 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. 52 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.

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”*. 
Safety FirstOperating instructionsPractical TipsTechnical Specifications

78Cockpit
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. 

254Wheels and tyres
Tyre pressure warning lamp on
When you switch on the ignition, the tyre pressure warning lamp  will
light up for about 2 seconds. There is a fault in the system if the indicator
stays on permanently after switching on the ignition. The instrument panel
also display TMPS (Tyre Pressure Monitoring System). Please contact the
nearest specialised workshop as soon as possible.
The tyre pressure warning lamp  lights up if the tyre pressure on one or
more wheels is significantly lower than the tyre pressure setting which was
confirmed by the driver ⇒ 
.
WARNING
● If the tyre pressure warning lamp lights up  you must slow down
immediately and avoid any severe braking or steering manoeuvres. Stop
the vehicle as soon as possible and check the tyres and their pressure.
● The driver is responsible for maintaining correct tyre pressures.
Therefore, the tyre pressure must be regularly checked.
● Under certain conditions (e.g. driving at high speeds, on ice and snow
or on poor road surfaces) the tyre pressure warning lamp  may not light
up immediately or not at all.
● Please ask your Technical Service or specialised workshop whether
run-flat tyres can be used on your vehicle. Fitting this type of tyre in an
undue manner could lead to your driving licence being taken away from
you. Furthermore, it may led to damage to the vehicle or, under certain
circumstances, may cause accidents.
● If you change normal tyres for run-flat tyres or vice versa, the control
unit must be reprogrammed by the Technical Service or a specialised
workshop.
Note
If you did not press the button for the tyre pressure monitoring system to
confirm a new tyre pressure setting after making changes to the tyre pres-
sures or changing one or more wheels, the warning lamp  may light up
although the tyre pressures are correct. In this case, stop the vehicle as
soon as possible and, after examining the tyres, press the button for the
tyre pressure monitoring system. 
