WARNING
•
If you do not pay attention to the wa
rning lights coming on and the corre-
sponding descriptions and warning notes, this may result in severe body injuries or major vehicle damage.•
The engine compartment of your car is
a hazardous area. There is a risk
of injuries, scalding, accidents and
fire when working in the engine
compartment, e.g. inspecting and replenis
hing oil and other fluids. It is also
essential to obse
rve all warnings
⇒page 160.
Note
•
Arrangement of the indicator lights depends on the model and model version.
The symbols shown in the following function
al description are to be found as indi-
cator lights in the instrument cluster.•
Operational faults are shown in the inst
rument cluster as red symbols (priority
1 - danger) or yellow symbols (priority 2 - warning).Turn signal system
Either the left
or right
indicator light flashes depending on the position of the
turn signal lever. The indicator light flashes at twice its normal rate if a turn signal light fails. This does not apply when towing a trailer. Switching off the hazard warning light system is switched on will cause all of the turn signal lights as well as both indicator lights to flash. Further information about the turn signal system
⇒page 52.
Turn signal system for vehicles towing a trailer

Technical Data
A fault in the entire brake system If the ABS warning light
comes on together with the brake system warning light
(handbrake must be released), there is
a fault not only in the ABS but also in
another part of the brake system
⇒
.
Electronic Differential Lock (EDL)* The EDL is a part of the ABS. A fault in th
e EDL is indicated by the ABS warning light
in the instrument cluster. Have the vehicle inspected immediately by your nearest specialist garage. Models fitted with ESP are equipped with
electronic differential lock (EDL).
If a significant fault occurs in the ABS system, a warning signal sounds additionally (3 peeps). Further information on the EDL
⇒page 132.
WARNING
•
If the brake system warning light
comes on together with the ABS
warning light
stop the vehicle immediatel
y and check the brake fluid
level in the reservoir
⇒page 167, “Brake fluid”. If the fluid level has dropped
below the MIN marking, do not drive any further - risk of accident! Obtain professional assistance.•
Pay attention to the following instru
ctions before checking the brake
fluid level and opening the bonnet
⇒page 160, “Working in the engine
compartment”.•
If the brake fluid is at
the correct level, the ABS control function has
failed. The rear wheels may then block ve
ry rapidly when braking. In certain
circumstances, this can result in the rear end of the car breaking away - risk of skidding! Drive carefully to the ne
arest specialist garage and have the
fault rectified.Traction control system (TCS) *
The warning light
comes on for a few seconds when the ignition is switched on.
The warning light flashes when a cont
rol cycle is activated while driving.
The warning light will come on and remains
on if the TCS is switched off or if there
is a fault in the system. The fact that the TCS system operates together with the ABS means that the TCS warning light will also come on if the ABS system is not operating properly. If the warning light
comes on immediately after starting the engine, the TCS
system can be switched off for technical
reasons. In this case, the TCS system can
be switched on again by swit
ching the ignition on and off. If the warning light goes
out, the TCS system is fully functional again. Further information about the TCS
⇒page 133, “Traction control system (TCS)”.
Electronic stability programme (ESP)*
The warning light
comes on for a few seconds when
the ignition is switched on.
Components of the ESP system also include the Traction Control System (TCS), the Electronic Differential Lock (EDL) and the Antilock Brake System (ABS). The warning light flashes when a control cycle is activated while driving.The warning light will come on and remains on
if the ESP is switched off or if there
is a fault in the system. The fact that the ESP system operates together with the ABS and the EDL means that the ESP warning light will also come on if
the ABS system is not operating properly.
If the warning light
comes on immediately after starting the engine, the ESP
system can be switched off for technical
reasons. In this case, the ESP system can
be switched on again by swit
ching the ignition on and off. If the warning light goes
out, the ESP system is fully functional again. Further information on the ESP
⇒page 131, “Electronic
stability programme
(ESP)*”.
Note
If the battery has been disconnected
and reconnected, the warning light
comes
on after switching on the ignition. The warn
ing light must go out after driving a short
distance.

Airbag systemDescription of the airbag systemGeneral information on the airbag systemThe front airbag system is complementary
to the three-point seat belts and offers
additional protection for the head and chest area of the driver and passenger in the event of a frontal collision. In the case of a violent side crash, the side airbags* reduce the risk of injuries to the occupants on the side of the collision
⇒
.
The airbag system is only functional af
ter the ignition has been switched on.
The operational readiness of the airbag system is monitored electronically. The airbag warning light comes on for a few seconds each time the ignition is switched on. The airbag system (according to vehicle equipment) consists of:•
an electronic control unit,
•
front airbag for the driver and the front seat passenger*,
•
side airbags*,
•
an airbag warning light in the instrument cluster,
•
Switch for front passenger airbag* in
front passenger storage compartment
⇒ page 121,•
Indicator light for a switched off front seat passenger airbag*
⇒page 121.
A fault in the airbag system exists if:•
the airbag indicator light do
es not light up when the ignition is switched on,
•
the warning light does not go out after
about 4 seconds after the ignition is
switched on,•
the airbag indicator light goes out and comes on again after the ignition is
switched on,•
the airbag indicator light comes
on or flickers when driving.
WARNING
•
To enable the occupants of a vehicle
to be protected with the greatest
possible effect when the airbag is deployed, the front seats must be ⇒ page 104, “Correct seated position” co
rrectly adjusted to
match the body
size of the occupant.•
If you do not fasten the seat belts when driving, lean too far forward or
adopt an incorrect seated position, yo
u are exposing yourself to increased
risk of injury in the event of an accident.•
Have the airbag system checked immedi
ately by a specialist garage if a
fault exists. Otherwise, there is a risk
of the airbag not being activated in the
event of an accident.•
No modifications of any kind may be
made to parts of the airbag system.
•
It is prohibited to manipulate individual parts of the airbag system as this
might result in the airbag being deployed.•
The protective function of the airbag system is sufficient for only one
accident. The airbag system must then
be replaced if the airbag has been
deployed.•
The airbag system needs no main
tenance during its working life.
•
If you sell your car, please hand over the complete vehicle documenta-
tion to the new owener. Please note that the documents relating to the possibility of deactivating the front passenger airbag are also part of the vehicle documents!•
If the vehicle or individual parts of the airbag system are scrapped, it is
essential to observe the relevant safety
precautions. Specialist garages are
familiar with these regulations.•
When disposing of vehicle or parts of the airbag system, it is important
to comply with the national legal requirements.

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral The ESP aids you maintain control of your vehicle in situations in borderline driving situations such as when negotiating a curve too fast. The risk of skidding is reduced and your vehicle thus offers greater driving stability depending on the conditions of the road surface. This occurs at all speeds. The following systems are integrated into the electronic stability programme:•
Electronic Differential Lock (EDL),
•
Traction control system (TCS),
•
Antilock brake system (ABS),
•
Brake Assist.
Operating principle The ESP switches on automatically when the engine is started and then conducts a self-test. The ESP control unit processes data from the individual systems. It also processes additional measurement data which are supplied by highly sensitive sensors: the rotational velocity of the vehi
cle about its vertical axis, the lateral accel-
eration of the vehicle, the brakin
g pressure and the steering angle.
The direction which the driver wishes to ta
ke is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual behaviour of the vehicle. If differences exis
t, such as the vehicle beginning to skid,
the ESP will automatically brake the appropriate wheel. The car is stabilised again by the forces which take effect when the wheel is braked. Intervention into the brake system takes place primarily on the outer front wheel of a vehicle which tends to oversteer (tendency for the rear of the vehicle to break away) while occurs this is on the inner re
ar wheel of a vehicle which tends to under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied by noises. The ESP operates in combination with the ABS
⇒page 135, “Antilock brake system
(ABS)*”. If there is a fault in the ABS system, the ESP also does not operate. The ESP warning light
⇒page 33 lights up in the instrument cluster when there is a
fault on the ESP. Switching off You can switch the ESP off and on again
as you wish, by pressing the button
⇒ fig. 139
. The ESP warning light
⇒page 33 lights up in the instrument cluster
when the ESP is switched off. The ESP should normally always be switched
on. It may be good practice in certain
exceptional cases, such as when you wish
to have wheel slip, to switch off the
system. Examples:
