For the sake of the environment
The heated rear window should be disconnected as soon as the glass is
demisted. By saving electrical power you can also save fuel.
Note
To avoid possible damage to the battery, an automatic temporary discon-
nection of this function is possible, coming back on when normal operating
conditions are re-established.
Hazard warning lights
The hazard warning lights are used to draw the attention of
other road users to your vehicle in emergencies.
Fig. 59 Centre console:
switch for hazard warn-
ing lights
If your vehicle breaks down:
1. Park your vehicle at a safe distance from moving traffic. 2. Press the button to switch on the hazard warning lights
⇒
.
3. Switch the engine off.
4. Apply the handbrake.
5. On a manual gearbox engage 1st gear. On an automatic, 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
when:
● 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. That is that 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 turn signals only work when the ignition is switched on. The corre-
sponding warning lamp or flashes in the instrument panel. The warn-
ing lamp flashes when the turn signals are operated, provided a trailer is
correctly attached and connected to the vehicle. If a turn signal bulb is de-
fective, the warning lamp flashes at double speed. If the trailer turn signal
bulbs are damaged, warning lamp does not light up. Change the bulb.
● The main beam headlights can only be switched on if the dipped beam
headlights are already on. The warning lamp then comes on in the instru-
ment panel.
● The headlight flasher comes on for as long as you pull the lever – even if
no other lights are switched on. The warning lamp then comes on in the
instrument panel.
● When the parking lights are switched on, the headlight and the tail light
on the corresponding side of the vehicle light up. The parking lights will on-
ly work if the key is removed from the ignition. If the lights are switched on,
an acoustic signal will be emitted while the driver door is open.
● If the turn signal lever is left on after the key has been taken out of the
ignition lock, an acoustic signal sounds when the driver door is opened.
This is a reminder to switch off the turn signal, unless of course you wish to
leave the parking light on. Interior lights

Activation
The system is activated by engagement of the reverse gear. A brief acoustic
signal 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.
Within a short distance of about 30cm, 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 decreases by 30% after 3 seconds from the start of the
system.
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 acoustic signal
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 an Authorised Service Centre 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.
CAUTION
● Please note that low obstacles detected by the system may no longer be
registered by the sensors as the car moves closer, so the system will not
give any further warning. Certain kinds of obstacles (such as wire fences,
chains, thin posts or trailer draw bars, high kerbs or painted railings etc)
may not always be detected by the system, so there is a risk of damaging
the vehicle in such cases.
● In some cases, obstacles with uniform edges and bumps may not be de-
tected immediately by the system due to their geometry. Take special care
of this type of obstacle (corners, rectangular objects, etc.), as they can
cause damage to the vehicle.
● Be especially careful when manoeuvring into a corner between two per-
pendicular walls. Carefully watch the approach of the wall to the side of the
vehicle (using the mirrors).
● The parking aid system does not replace use of the mirrors for manoeu-
vres.

163
Driving
● External ultra-sonic sources (pneumatic drills, construction machinery,
other vehicles with PDC) may interfere with the operation of the system.
● Periodic cleaning of the sensors, take care not to damage or scratch
them. When cleaning with high pressure washers or steam cleaners, the
sensors should be sprayed for only a very short period and from a distance
of more than 10 cm.
Cruise speed* (Cruise control system)
Description
The cruise control system is able to maintain the set speed
in the range of 30 km/h to 180 km/h. Once the speed setting has been saved, you may take your foot off the ac-
celerator.
WARNING
It could be dangerous to use the cruise control system if it is not possible
to drive at constant speed.
● Do not use the cruise control system when driving in dense traffic, on
roads with lots of bends or on roads with poor conditions (with ice, slip-
pery surfaces, loose grit or gravel), as this could cause an accident.
● Always switch the cruise control system off after using it in order to
avoid an involuntary use.
● It is dangerous to use a set speed which is too high for the current
road, traffic or weather conditions. Risk of accident.
Note
The cruise control cannot maintain a constant speed when descending
downhill. The vehicle will accelerate due to its own weight. Use the foot
brake to slow the vehicle.

Intelligent technology
TCS helps the vehicle to start moving, accelerate and climb a gradient in
slippery conditions where this may otherwise be difficult or even impossi-
ble.
The TCS is switched on automatically when the engine is started. If necessa-
ry, it may be turned on or off by briefly pushing the ESP button on the centre
console.
When the TCS is off, the warning lamp is lit. The TCS should normally be
left on. Only in exceptional circumstances, when the slipping of the wheels
is required, can they be disconnected using the ESP 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 TCS should be switched on again as soon as possible.
WARNING
● It must be remembered that TCS 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. Do not let the extra safety afforded by TCS tempt you
into taking any risks when driving, this can cause accidents.
CAUTION
● In order to ensure that TCS function correctly, all four wheels must be fit-
ted with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
● Modifications to the vehicle (e.g. to the engine, the brake system, run-
ning gear or any components affecting the wheels and tyres) could affect
the efficiency of the ABS and TCS. 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.
By using the ESP sensors and signals, the XDS system is able to detect and
correct this effect.
Through the ESP, the XDS brakes the inner wheel, thereby counteracting the
excess drive torque in this wheel. This means that the driver's desired tra-
jectory is much more precise,
The XDS system operates in combination with the ESP and is always active,
even when the traction control, TCS, is disconnected.
Electronic Stability Programme (ESP)* General notes
The Electronic Stability Programme increases the vehicle's
stability on the road.
The Electronic Stability Programme helps reduce the danger of skidding.
The Electronic Stability Programme (ESP) consists of ABS, EDL and TCS.
