Seat belts
called “kinetic energy” is created both in the
passengers and inside the vehicle.
The amount of “kinetic energy” depends on
the speed of the vehicle and the weight of
the vehicle and its passengers. The higher
the speed and the greater the weight, the
more energy there is to be “absorbed” in an
accident.
The most significant factor, however, is the
speed of the vehicle. If the speed doubles
from 25 km/h (15 mph) to 50 km/h
(30 mph), for example, the corresponding ki-
netic energy is multiplied by four.
Because the vehicle occupants in our exam-
ple are not restrained by seat belts, in the
event of crashing against a wall, all of the oc-
cupants' kinetic energy will be absorbed
solely by said impact.
Even at speeds of 30 km/h (19 mph) to
50 km/h (30 mph), the forces acting on bod-
ies in a collision can easily exceed one tonne
(1000 kg). At greater speed these forces are
even higher.
Vehicle occupants not wearing seat belts are
not “attached” to the vehicle. In a head-on
collision, they will move forward at the same
speed their vehicle was travelling just before
the impact. This example applies not only to
head-on collisions, but to all accidents and
collisions. Even at low speeds the forces acting on the
body in a collision are so great that it is not
possible to brace oneself with one's hands.
In a frontal collision, unbelted passengers
are thrown forward and will make violent con-
tact with the steering wheel, dash panel,
windscreen or whatever else is in the way
››› Fig. 52 .
It i
s also important for rear passengers to
wear seat belts properly, as they could other-
wise be thrown forward violently through the
vehicle interior in an accident. Passengers in
the rear seats who do not use seat belts en-
danger not only themselves but also the front
occupants ››› Fig. 53. How t

Control lamp for airbag and seat belt
tensioner The control lamp monitors all airbags and
seat belt tensioners in the vehicle, including
control units and wiring connections.
Monitoring of airbag and belt tensioner
system
Both the airbag and belt tensioner systems
operation is constantly monitored electroni-
cally. The control lamp
will light up for a
few seconds every time the ignition is switch-
ed on (self-diagnosis).
The system must be checked when the
control lamp :
● does not light up when the ignition is
switched on,
● 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.
In the event of a malfunction, the warning
lamp remains on continuously. Have the air-
bag system inspected immediately by a spe-
cialised workshop.
If any of the airbags are disabled by a Techni-
cal Service, the warning lamp flashes for sev- eral more seconds after verification and will
turn off if there is no fault. WARNING
● If there is a malfunction, the airbag and
belt tensioner system cannot properly per-
form its protective function.
● If a malfunction occurs, have the system
checked immediately by a specialised work-
shop. Otherwise, in the event of an accident,
the airbag system and belt tensioners may
not be triggered, or may not be triggered cor-
rectly. Airbag overview

Airbag system
Fig. 57
Front passenger airbag located in

the steering wheel
››› Fig. 56 and the airbag
f or the fr
ont passenger is located in the dash
panel ››› Fig. 57. Airbags are identified by the
wor
d “AIRBAG”.
The airbag covers fold out of the steering
wheel and dashboard respectively when the
driver and front passenger airbags are trig-
gered ››› Fig. 57
. The airbag covers remain connected to the steering wheel or the dash
panel.
In conjunction with the seat belts, the front
airbag system gives the driver and the front
passenger additional protection for the head
and chest in the event of a severe frontal col-
lision.
The special design of the airbag allows the
controlled escape of the propellant gas when
an occupant puts pressure on the bag. Thus,
the head and chest are surrounded and pro-
tected by the airbag. After the collision, the
airbag deflates sufficiently to allow visibility.
WARNING
● The seat belts and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 30, Proper sitting
position for occupants.
● The deployment space between the front
passengers and the airbags must not in any
case be occupied by other passenger, pets
and objects.
● The airbags provide protection for just one
accident; replace them once they have de-
ployed.
● It is also important not to attach any ob-
jects such as cup holders or telephone
mountings to the surfaces covering the air-
bag units.
● Do not attempt to modify components of
the airbag system in any way. Side airbags*

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-
ther information on the cruise control system

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.

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
.
Fuel level/reserve It lights up when only 7 litres of fuel remain
in the tank, and an
acoustic signal*
al
so
sou
nds. It reminds you to fuel up the fuel
tank as soon as possible ›››
page 163.
Door open display* This warning lamp lights up if one of the
doors is open.
The warning light
should go off when all
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.
For further information see
››› page 93.
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.

Dash panel
Note
When towing the vehicle with the engine
stopped or due to a fault in the power steer-
ing, this will not operate. The vehicle can still
be steered, but it will require greater force to
turn the steering wheel. Emission control system*
Control lamp
flashes:
When ther e i
s misfiring that can damage the
catalytic converter. Reduce speed and drive
carefully to the nearest specialised workshop
to have the engine checked.
The control lamp lights up:
If a fault has developed during driving which
has reduced the quality of the exhaust gas
(e.g. lambda probe fault). Reduce speed and
drive carefully to the nearest specialised
workshop to have the engine checked.
Level*/Temperature of the coolant There is a fault if:
● The warning symbol does not go out again
after a few seconds.
● The warning lamp lights up or flashes while
the vehicle is moving, and three acoustic
warning signals ›
›
› are emitted.This means that either the coolant level is too
low or the coolant temperature is too high.
Coolant temperature too high
If the warning lamp comes on,
stop the vehi-
cle, turn off the engine and wait for it to cool
down. Check the coolant level.
If the c
oolant level is correct, the overheating
may be caused by a malfunction of the radia-
tor fan. Check the radiator fan fuse and have
it replaced if necessary ››› page 195.
If the control lamp lights up again after driv-
ing on for a short distance, stop the vehicle
and switch the engine off
. Contact a Techni-
cal Service or a specialised workshop.
Coolant level too low
If the warning lamp comes on , stop the vehi-
cle, turn off the engine and wait for it to cool
down
. First check the coolant level. If the lev-
el of the coolant is below the “MIN” mark,
top up with coolant liquid ››› .
WARNING
● If your vehicle is immobilised for technical
reasons, move it to a safe distance from traf-
fic. Turn the engine off, turn the hazard lights
on and place the warning triangle.
● Never open the bonnet if you can see or
hear steam or coolant escaping from the en-
gine compartment. Risk of scalding. Wait un- til you can no longer see or hear escaping
steam or coolant.
●
The engine compartment is a dangerous
area. Before carrying out any work in the en-
gine compartment, switch off the engine and
allow it to cool down. Always note the corre-
sponding warnings ››› page 166. Alternator
This warning lamp signals a fault in the alter-
nator.
The warning lamp lights up when the igni-
tion is switched on. It should go out when the
engine has started running.
If the warning lamp
lights up while driv-
ing, the alternator is no longer charging the
battery. You should immediately drive to the
nearest specialised workshop.
You should avoid using electrical equipment
that is not absolutely necessary because this
will drain the battery.
Turn signals Depending on which turn signal is operating,
either the left
or right turn signal lamp
flashes. Both control lamps will flash at the
same time when the hazard warning lights
are switched on. »
