Cockpit
Main beam headlights 
This control lamp lights up when the main beams are on.
The warning lamp  is switched on once main beams are on or once the
headlight flasher is operating.
For further information see ⇒ page 107. 
Electro-hydraulic steering* 
The level of steering assistance depends on the vehicle speed and on the
steering wheel turning speed.
The control 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 steering system if the lamp does not
go out or lights up whilst the vehicle is in motion. Take the vehicle to the
Technical Service as soon as possible.
Note
When towing the vehicle with the engine stopped or due to a fault in the
power steering, this will not operate. The vehicle can still be steered, but it
will require greater force to turn the steering wheel. Emission control system* 
This warning lamp monitors the exhaust system.
Control lamp  flashes:
When there is misfiring that can damage the catalytic converter. Reduce
speed and drive carefully to the nearest specialised workshop to have the
engine checked.
Control lamp  is lit:
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. 
Coolant level*/temperature 
The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.
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 tempera-
ture is too high.
Coolant temperature too high
If the warning light comes on, stop the vehicle, switch off the engine and
wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunc-
tion of the radiator fan. Check the radiator fan fuse and have it replaced if
necessary ⇒ page 237. 

Anti-theft alarm system*
Description of anti-theft alarm system*
The anti-theft alarm triggers if unauthorised movements are
detected around the vehicle.
The anti-theft alarm makes it more difficult to break into the vehicle or steal
it. The system will initiate acoustic and optical warning signals when your
vehicle is tried to be forced.
The anti-theft alarm system is automatically switched on when locking the
vehicle. For this, either rotate the key in the locking position or press button 
2 on the radio frequency remote control*. The system is immediately ac-
tivated and the turn signal light located on the driver door will flash along
with the turn signals, indicating that the alarm and the locking security sys-
tem (double lock) have been turned on.
If any of the doors or the bonnet are open, they will not be included in the
protection zones of the vehicle when the alarm is connected. If the door or
the bonnet are subsequently closed, they will be automatically included in
the protection areas of the vehicle and the turn signals will flash according-
ly when the doors close.
● The turn signal light will flash twice on opening and deactivating the
alarm.
● The turn signal light will flash once on closing and activating the alarm.
When does the system trigger an alarm?
The system triggers an alarm if the following unauthorised actions are car-
ried out when the vehicle is locked: ●
Opening of vehicle with mechanical key without switching ignition on
within the next 15 seconds
● Opening a door
● Opening the bonnet
● Opening the rear lid
● Ignition switched on with a non-validated key.
● Movements in the driving compartment (vehicles with a volume sensor)
● Towing of the vehicle 1)
● Tilt angle (tow-away protection) 1)
● Undue manipulation of the alarm
● Battery handling
The acoustic signals sound and the turn signals flash for approx. 30 sec-
onds. This may be repeated up to 10 times depending on the country.
Opening all the doors in manual mode
In vehicles without alarm, when opening the driver door manually all the
doors are opened.
How to switch the alarm off
To deactivate the anti-theft alarm, turn the key in the opening direction,
open the door and switch the ignition on, or press the unlock button 
on
the remote control.
In vehicles equipped with an anti-theft alarm system, you have 15 seconds
to insert the key in the ignition lock and activate the ignition if the vehicle is
opened using the driver door key.
Otherwise, the alarm will trigger for 30 sec. and the ignition will be blocked. 

4. Apply the handbrake.
5. On a manual gearbox engage 1st gear. On an automatic gear- box, move the selector lever to P.
6. Use the warning triangle to draw the attention of other road users to your vehicle.
7. Always take the vehicle key with you when you leave the vehi- cle.
Switch on the hazard warning lights to warn other road users, for example:
● reaching the tail end of a traffic jam,
● there is an emergency
● your vehicle breaks down due to a technical fault,
● you are towing another vehicle or your vehicle is being towed.
All turn signals flash simultaneously when the hazard warning lights are
switched on. The two turn signal turn signal lamps   and the turn signal
lamp in the switch  will flash at the same time. The hazard warning lights
also work when the ignition is switched off.
WARNING
● The risk of an accident increases if your vehicle breaks down. Always
use the hazard warning lights and a warning triangle to draw the atten-
tion of other road users to your stationary vehicle.
● Never park where the catalytic converter could come into contact with
inflammable materials under the vehicle, for example dry grass or spilt
petrol. This could start a fire!
Note
● The battery will run down if the hazard warning lights are left on for a
long time, even if the ignition is switched off.
● The use of the hazard warning lights described here is subject to the rel-
evant statutory requirements. 

Safety
Electronic stability control (ESC)*
The ESC helps make driving safer in extreme driving condi-
tions.
Fig. 109 Detailed view of the dash panel: ESC switch.The Electronic Stability Control (ESC) contains the electronic differential lock
(EDL) and the traction control system (ASR). The ESC works together with
the ABS. Both control lamps will light up if the ESC or ABS systems are faul-
ty.
The ESC system is started automatically when the engine is started.
The ESC system is always active and cannot be switched off. The ESC switch
only switches the ASR off.
WARNING
● Do not forget that the Electronic stability control ESC cannot defy the
laws of physics. This should be kept in mind, particularly on slippery and
wet roads and when towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. The greater safety provided by the ESC should not
encourage you to run any risks.
● Please refer to the corresponding warning notes on ESC in
⇒ page 174, Intelligent technology.

Information regarding the “cleanliness” of the particulate filter
The exhaust system manager detects that the diesel particulate filter is
nearly saturated and contributes to self-cleaning by recommending the opti-
mal gear. For this purpose, it might be necessary to drive momentarily with
a high rpm ⇒  page 70.
WARNING
The gear change indicator is only an auxiliary function and in no case
should be a substitute for careful driving.
● The responsibility of choosing the correct gear depending on the sit-
uation (e.g. overtaking, driving up or down a slope or towing a trailer)
lies with the driver.
For the sake of the environment
Selecting the correct gear can help to save fuel.
Note
The recommended gear display is switched off when the clutch pedal is
pressed. 
Kick-down feature
This feature allows maximum acceleration. If you press the accelerator down thoroughly, the gearbox automatically
changes down, depending on speed and engine speed, into a lower gear to
take full advantage of give the vehicle maximum acceleration.
The gearbox does not change gear until the engine reaches the maximum
determined engine speed for the gear.
WARNING
You could lose control of the vehicle if you accelerate on slippery road
surfaces. Risk of serious injury.
● Be particularly careful when using the kick-down features on slippery
road surfaces. With a fast acceleration, the vehicle could lose traction
and skid.
● You should use the kick-down feature only when traffic and weather
conditions allow it to be used safely.

Handbrake Using the handbrake
The handbrake should be applied firmly to prevent the vehi-
cle from accidentally rolling away.

Driving
The front parking aid is an audible aid that warns against obstacles both
behind and in front of the vehicle ⇒ page 169.
Apart from the acoustic signals, when the vehicle is equipped with a porta-
ble navigator (PND), this visually displays information regarding front and/
or rear areas. 
Rear parking aid
The parking aid system will use an audible warning to indi-
cate of the approach of any object towards the rear of the ve-
hicle. Description
The acoustic parking aid system will measure the distance between the rear
of the vehicle and any possible obstacle using four ultrasonic sensors loca-
ted on the rear bumper. The measuring range of the sensors starts approxi-
mately and depending on the nature of the obstacle at a distance of:
● side of the rear bumper: 0.6 m
● middle of the rear bumper: 1.6 m
Activation
The system is activated by engagement of the reverse gear. A brief audible
warning confirms the activation and correct function of the system.
Reverse gear
The distance warning will begin as soon as an obstacle is detected by the
system. The frequency of the bleeps emitted by the system will increase rap-
idly as the vehicle approaches the obstacle. After a distance lower than ap-
proximately 30 cm, a continuous signal sounds (stop signal). The driver
should not reverse any further. Models with a factory-fitted towing bracket: When the vehicle is less than
0.35 m away from the obstacle the warning tone will sound continuously.
The driver should then not reverse any further.
The warning tone volume decreases by 30% 3 seconds after it is triggered
if
the detected obstacle stays at a constant distance from the vehicle .
Provided that it is not in continuous mode, the tone on the parking aid sys-
tem stops when it detects a wall parallel to the vehicle.
Trailer towing
For vehicles factory-fitted with a towing bar, the parking aid system will not
be activated by the engagement of the reverse gear when pulling a trailer,
as the trailer's electric connector will be plugged into the vehicle.
Possible faults
If a continuous beep sounds for some seconds when the reverse gear is en-
gaged, this indicates that there is a fault in the parking aid system. If the
fault continues until the ignition is turned off, the audible warning of the
fault will not be emitted every time the system is reactivated (by engaging
the reverse gear). Thus, the system ready indication will not sound either.
Have the fault repaired by a Technical Service as soon as possible.
If there is no ready signal or no acoustic warning signal, then the parking
aid loudspeaker is faulty and may not warn of obstacles. To ensure that the
system works properly, the sensors must be kept clean and free of ice and
snow.
WARNING
● The sensors have blind spots in which obstacles may not be detected.
● Always look out for small children and animals because the system
will not always detect them. Always pay attention when reversing to
avoid accidents.
● The parking aid is not a replacement for driver awareness. The driver
must take full responsibility for parking and other manoeuvres. 

Driving
Front parking aid
The parking aid system will sound an audible warning to in-
dicate of the approach of any object towards the front or
rear of the vehicle.
Description
The acoustic parking aid system measures the distance between the vehicle
and any possible obstacle using 8 ultrasonic sensors (4 of which are loca-
ted on the rear bumper and 4 of which are located on the front bumper).
The measuring range of the sensors starts approximately and depending on
the nature of the obstacle at a distance of:
● side of the front bumper: 0.6 m
● middle of the front bumper: 1.2 m
● side of the rear bumper: 0.6 m
● middle of the rear bumper: 1.6 m
Activation
The system may be activated in the following ways:
● Engage the reverse gear (a brief, sharp acoustic signal confirms activa-
tion and the correct operation of the system) or
● Push the central console button  (a brief confirmation signal will
sound and the button’s LED will light up).
Disconnection
The system may be deactivated in the following ways:
● Drive forwards at more than approx. 10 km/h (6 mph) or else
● Press the  button, or
● Switch the ignition off Manoeuvres
The distance warning will begin as soon as an obstacle is detected in the
system's field of detection (front and rear). The frequency of the bleeps
emitted by the system will increase rapidly as the vehicle approaches the
obstacle. Two speakers, one in the front and one in the rear, indicate the lo-
cation of the obstacle (either front or rear).
After a distance lower than approximately 30 cm, a continuous signal
sounds (stop signal). At this point the driver should halt the vehicle.
Models with a factory-fitted towing bracket: When the vehicle is less than
0.35 m away from the obstacle the warning tone will sound continuously.
The driver should then not reverse any further.
The warning tone volume decreases by 30% 3 seconds after it is triggered if
the detected obstacle stays at a constant distance from the vehicle.
Provided that it is not in continuous mode, the tone on the parking aid sys-
tem stops when it detects a wall parallel to the vehicle.
Trailer towing
For vehicles factory-fitted with a towing bar, the parking aid system will not
be activated by the engagement of the reverse gear when pulling a trailer,
as the trailer's electric connector will be plugged into the vehicle.
Possible faults
If a continuous, sharp beep sounds for various seconds, there is a fault in
the parking aid system.
If the fault continues until the ignition is turned off, the audible warning of
the fault will not be emitted every time the system is reactivated (by engag-
ing the reverse gear or pressing the button). Thus, the system ready indi-
cation will not sound either. Have the fault repaired by a Technical Service
as soon as possible.
If there is no ready signal or no acoustic warning signal, then the parking
aid loudspeaker is faulty and may not warn of obstacles. To ensure that the

176Intelligent technology
The ASR helps the car to start moving, accelerate and climb a gradient in
slippery conditions, where this may otherwise be difficult or even impossi-
ble.
The ASR automatically switches on when the engine is started. If necessary,
it may be turned on or off by briefly pushing the ESC button on the centre
console.
When the ASR is off, the warning lamp  is lit. The ASR should normally be
left on. Only in exceptional circumstances, when the slipping of the wheels
is required, can they be disconnected using the ESC button, for example.
● With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on loose surfaces
● When the vehicle is bogged-down, to free it by rocking.
The ASR should be switched on again as soon as possible.
WARNING
● Remember that not even the ASR can defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. The greater safety provided by the ASR should not
encourage you to run any risks.
CAUTION
● To ensure that the ASR works correctly, identical tyres should be fitted
on all four wheels. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
● Any modifications made to the vehicle (for example, to the engine,
brake system, running gear or to the combination of wheels and tyres) may
affect the operation of the ABS and ASR. XDS*
Driveshaft differential
When taking a bend, the driveshaft differential mechanism allows the outer
wheel to turn at a higher speed than the inner wheel. In this way, the wheel
that is turning faster (outer wheel) receives less drive torque than the inner
wheel. This may mean that in certain situations the torque delivered to the
inner wheel is too high, causing the wheels to spin. On the other hand, the
outer wheel is receiving a lower drive torque than it could transmit. This
causes an overall loss of lateral grip on the front axle, resulting in under-
steer or “lengthening” of the trajectory.
The XDS system can detect and correct this effect via the sensors and sig-
nals of the ESC.
Via the ESC, the XDS will brake the inside wheel and counter the excess
driving torque of that wheel. This means that the driver's desired trajectory
is much more precise,
The XDS system works in combination with the ESC and is always active,
even when the ASR traction control is disconnected.
