Airbag system
The airbag system operation is monitored
electronically. The airbag control lamp will il-
luminate for a few seconds every time the ig-
nition is switched on (self-diagnosis).
There is a fault in the system if the control
lamp 
:
● doe
s not light up when the ignition is
switched on ››› page 42
,
● turns off after 4 seconds after the ignition
is switched on
● turns off and then lights up again after the
ignition is switched on
● illuminates or flashes while the vehicle is
moving.
The airbag system is not triggered if:
● the ignition is switched off
● there is a minor frontal collision
● there is a minor side collision
● there is a rear-end collision
● the vehicle turns over. WARNING
● The seat belts and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 30, Proper sitting
position for occupants.
● If a fault has occurred in the airbag system,
have the system checked immediately by a
specialised workshop. Otherwise, during a frontal collision the system might not trigger
correctly or may fail to trigger at all.
Airbag activation
The airbags deploy extremely rapidly, within
thousandths of a second, to provide addi-
tional protection in the event of an accident.
A fine dust may develop when the airbag de-
ploys. This is normal and it is not an indica-
tion of fire in the vehicle.
The airbag system is only ready to function
when the ignition is on.
In special accidents instances, several air-
bags may activate at the same time.
In the event of minor head-on and side colli-
sions, rear-end collisions, overturning or roll-
over of the vehicle, airbags
do not activate.
Activation factors
The conditions that lead to the airbag system
activating in each situation cannot be gener-
alised. Some factors play an important role,
such as the properties of the object the vehi-
cle hits (hard/soft), angle of impact, vehicle
speed, etc.
Deceleration trajectory is key for airbag acti-
vation. The control unit analyses the collision trajec-
tory and activates the respective restraint
system.
If the deceleration rate is below the prede-
fined reference value in the control unit the
airbags will not be triggered, even though
the accident may cause extensive damage to
the car.
The following airbags are triggered in
serious head-on collisions
● Driver airbag.
● Front passenger front airbag
The following airbags are triggered in
serious side-on collisions
● Front side airbag on the side of the acci-
dent.
● Rear side airbag on the side of the acci-
dent.
● Curtain (head) airbag on the side of the ac-
cident.
In an accident with airbag activation:
● the interior lights switch on (if the interior
light switch is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked;
● the fuel supply to the engine is cut.

● Failure to observe control lamps and warn-
ing messages can result in serious personal
injuries or damage to your vehicle.
● The risk of an accident increases if your ve-
hicle breaks down. Use a warning triangle to
draw the attention of other road users in or-
der to prevent danger to third parties. ●
The engine compartment is a dangerous
area. Before you open the bonnet to work on
the engine or in the engine compartment,
switch the engine off and allow it to cool to
reduce the risk of burns or other injuries.

››› page 166. Note
● The appropriate control lamp for a fault will
light up in vehicles without warning or infor-
mation messages in the display.
● In vehicles with warning or information
messages on the screen, the appropriate con-
trol lamp for a fault will light up and a warn-
ing or information message will also appear
on the screen. Warning symbols
There are red warning symbols (priority 1)
and yellow warning symbols (priority 2).
Warning messages, Priority 1 (red)
If one of these faults occurs, the warning
lamp will light up or flash and will be accom-
panied by
three audible warnings. This is a
danger warning. Stop the vehicle and switch

. Take the vehicle to
a specialised workshop as soon as possible
and have the engine checked.
Soot accumulation in the diesel
engine particulate filter*  If the control lamp
 lights up you should
help the filter clean itself by driving in the ap-
propriate manner.
To do this, drive about 15 minutes in fourth
or fifth gear (automatic gearbox: S gear
range) at a minimum speed of 60 km/h
(37 mph), with the engine running at approxi-
mately 2,000 rpm. In this way, the soot build
up in the filter is burned. When cleaning is
successful, the control lamp turns off.
If the lamp  does not turn off, or the three
lamps turn on (particulate filter , fault in
the emission control system  and glow
plugs ), drive the vehicle to a specialised
workshop and have the fault repaired at the
earliest opportunity. WARNING
● Always drive according to the road weather
conditions, the terrain and traffic. Driving rec- ommendations should never lead to illegal
manoeuvres in surrounding traffic.
●
The diesel engine particulate filter may
reach extremely high temperatures; in this
case the vehicle should be parked so that it
does not enter into contact with highly flam-
mable materials underneath the vehicle. Oth-
erwise there is a risk of fire. Engine oil pressure
 If this warning lamp
 is red it indicates
that the engine oil pressure is too low.
If this warning symbol starts to flash, and is
accompanied by three audible warnings,
switch off the engine and check the oil level.
If necessary, add more oil ››› page 170.
If the warning lamp flashes although the oil
level is correct, stop driving. Do not even run
the en gine at

idle speed! Obtain technical as-
sistance.
Checking the oil level 
If the warning lamp is yellow  the engine
oil level should be checked as soon as possi-
ble. Top up the oil ››› page 170 at the next
opportunity.
Oil level sensor faulty* 
If the  yellow warning lamp flashes, take
the vehicle to a specialised workshop to have the oil level sensor checked. Until then it is
advisable to check the oil level every time
you refuel.
Bulb defect*  The 
warning lamp lights up when there is
a f

ault on the turn signals, headlights, side
lights and fog lights.
Washer fluid*  This warning lamp lights up to indicate that
the windscreen washer level is very low.

Operation
There is a fault in the ABS if:
● The warning lamp 
does not light up
when the ignition i
s switched on.
● The control lamp does not go out again af-
ter a few seconds.
● The control lamp lights up when the vehicle
is moving.
The vehicle can still be braked in the normal
way, without the ABS function. Take the vehi-
cle to a specialised workshop as soon as
possible. For further information on the ABS
see the ››› page 140
.
If there is a fault in the ABS, the ESC* and the
tyre pressure control lamp will also light up.
Brake system fault
If the ABS warning lamp  lights up together
with the brake warning lamp , there is a
fault in the ABS function and in the brake
system ››› .
WARNING
● Before opening the bonnet, read and ob-
serve the warnings ››› page 166, Working in
the engine compartment.
● If the br

ake system warning lamp  should
light up together with the ABS warning lamp
, stop the vehicle immediately and check
the brake fluid level in the reservoir
››› page 173, Brake fluid. If the brake fluid
lev

el has dropped below the “MIN” mark you must not drive on. Risk of accident. Obtain
technical assistance.
●
If the brake fluid level is correct, the fault in
the brake system may have been caused by a
failure of the ABS system. This could cause
the rear wheels to lock quickly when you
brake. This could cause the rear to break
away. Risk of skidding. Stop the vehicle and
seek technical assistance. Differential lock fault (EDL)*
The EDL operates along with the ABS in vehi-
cles equipped with Electronic Stability Con-
trol (ESC)*.
A malfunction in the EDL is indicated by the
ABS control lamp
. Take the vehicle to a
specialised workshop as soon as possible.
For further information on the EDL see
››› page 139, Electronic differential lock
(EDL)* .
T r

action control system (ASR)*  /  The traction control system prevents the driv-
en wheels from spinning when the vehicle is
accelerating.
There are two warning lamps for the traction
control system:
 and . Both warning lamps
light up together when the ignition is switch-
ed on and should turn off after approximately 2 seconds. This is the time taken for the func-
tion check.
The

lamp has the following function:
● It

flashes when the ASR is working if the ve-
hicle is moving.
If the system is deactivated or if it has any
fault, the warning lamp will remain lit. The
warning lamp will also light up if a fault
should occur in the ABS because the ASR op-
erates in conjunction with the ABS. For fur-
ther information, see ››› page 141.
The  lamp provides information about the
disconnection status of the system:
● It stays lit when the ASR is disconnected
when pressing the  switch.
By pressing it again, the ASR function is reac-
tivated and the warning lamp switched off.
Electronic Stability Control (ESC)*  /
 There are two control lamps for the electronic
stability control. The lamp
 provides infor-
mation concerning function and  disconnec-
tion status.
Both warning lamps light up together when
the ignition is switched on and should turn
60

Dash panel
off after approximately 2 seconds. This is the
time taken for the function check.
This programme includes the ABS, EDL and
ASR. It also includes emergency braking as-
sistance (BAS).
The warning lamp 
has the following
f
unctions:
● It flashes whilst driving when the ASR/ESC
is activated.
● It will light up if there is a fault in the ESC.
● As the ESC operates in conjunction with the
ABS, the ESC light will also come on if a fault
should occur in the ABS.
If the ESC control 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 control 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. Brake system*  Situations in which the warning lamp lights
up 
● the br ak

e fluid level is too low
››› page 173.
● there i

s a fault in the brake system.
This warning lamp can light up together with
the ABS system warning lamp. WARNING
● If the brake warning lamp does not go out
or if it lights up when driving, the brake fluid
level in the reservoir is too low so there is a
risk of an accident ››› page 173, Brake fluid.
Stop the vehicle and do not drive on. Obtain
technical assistance.
● If the brake warning lamp lights up  to-
gether with the ABS lamp  this could be
due to an ABS fault. This could cause the rear
wheels to lock quickly when you brake. This
could cause the rear to break away. Risk of
skidding. Stop the vehicle and seek technical
assistance. Cruise speed (cruise control)* 
The warning lamp  comes on when the
cruise control system is switched on. For fur-

revolutions and with it, using the ESC, the
wheel diameter of each wheel. If the diame-
ter of a wheel changes, the tyre control lamp
 lights up. The wheel diameter changes
when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a
load.
● The wheels of one axle are under more
pressure (for example, driving with a trailer or
on steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed. »

Operation
Tyre pressure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 71 button must be
k ept
pressed down, with the ignition on, until
an acoustic signal is heard.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the inside of the fuel flap). If the
tyre monitor system button is pressed down,
the new tyre pressures are confirmed.
The tyre pressure control lamp  lights up
If the tyre pressure of a wheel is much lower
than the value set by the driver, then the tyre
pressure control lamp ››› will light up.
WARNING
● When the tyre pressure control lamp lights
up, reduce speed immediately and avoid any
sudden turning or braking manoeuvre. Stop
when possible, and check the tyre pressure
and status.
● The driver is responsible for maintaining
correct tyre pressures. For this reason, tyre
pressure must be regularly checked.
● Under certain circumstances (e.g. when
driving in a sporty manner, in winter condi-
tions or on a dirt track) the tyre control lamp
may light up belatedly or may function incor-
rectly. Note
If the battery is disconnected, the yellow
warning lamp  lights up after turning the
ignition on.
This should turn off after a brief
journey. Speed selector lever lock* 
The brake pedal must be depressed when
this warning lamp lights up. This is necessary
when the automatic gearbox* selector lever
is moved out of the positions
P
or N
.

the doors are closed correctly. Rear lid open*  The warning lamp 
should switch off when
the r

ear lid is fully closed.
Main beam headlights  The warning lamp  lights up when the main
beams are on or when the headlight flasher
is operated.

Electro-hydraulic steering*  The level of steering assistance depends on
the vehicle speed and on the steering wheel
turning speed.
The warning lamp should light up for a few
seconds when the ignition is switched on. It
should go out once the engine is started.
There is a fault in the electro-hydraulic steer-
ing system if the lamp does not go out or
lights up whilst the vehicle is in motion. Take
the vehicle to technical services as soon as
possible.
