The next speed down will automatically be selected if speed
⇒ page 116, fig. 81 or is selected when the vehicle stops. The set speed
will be resumed when the vehicle starts again
•
The windscreen will be wiped again after approximately five seconds once
the “automatic wipe/wash system” has been operated while the vehicle is in
transit.
•
When the “intermittent wipe function” is on, the intervals are directly
proportional to the speed. This way, the higher the vehicle speed the shorter
the intervals.
•
The wiper will try to wipe away any obstacles that are on the windscreen.
The wiper will stop moving if the obstacle blocks its path. Remove the
obstacle and switch the wiper back on again.
•
Before removing any objects that may be trapped in the side areas of the
windscreen, always move the wiper arms to the service position
(horizontal).
Rain sensor*
The rain sensor controls the frequency of the windscreen
wiper intervals, depending on the amount of rain.

Switching on anti-dazzle function
– Press button ⇒fig. 85 . Warning lamp is lit.Anti-dazzle function
The anti-dazzle function is activated ev ery time the ignition is switched on.
The green indicator lamp lights up in the mirror housing.
When the anti-dazzle function is activated the interior mirror will darken auto-
matically according to the amount of light it receives (for example from the
headlights of a vehicle behind). The anti-dazzle function is cancelled if
reverse gear is engaged.
Note
•
The automatic anti-dazzle function will only work properly if the sun
blind* for the rear window is retracted and there are no other objects
preventing light from reac hing the interior mirror.
•
If you have to stick any type of sticker on the windscreen, do not do so in
front of the sensors. Doing so could prevent the anti-dazzle function from
working well or even from working at all.
Exterior mirrors
The exterior mirrors can be adjusted using the rotary knob in
the centre console.Basic setting of exterior mirrors

•
Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.
Acoustic parking aid system*Rear parking aid
The parking aid system will use an acoustic signal to warn of
the approach of any object towards the rear of the vehicle.Description
The acoustic parking aid system will measure the distance between the rear
of the vehicle and any possible obstacle using four ultrasonic sensors located
on the rear bumper. The measuring range of the sensors starts at approxi-
mately and depending on the nature of the obstacle at a distance of:•
side of the rear bumper: 0.8 m
•
centre of the rear bumper: 1.3 m
Activation
The system is activated by engagement of the reverse gear. A brief acoustic
signal confirms the activation and correct function of the system.
Reversing
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
rapidly as the vehicle approaches the obstacle.
Within a short distance of about 25 cm, a continuous signal sounds (stop
signal). The driver should not reverse any further. Trailer towing
For vehicles fitted with a tow bar by the manufacturer, the parking aid system
will not be activated by the engagement of the reverse gear when pulling a
trailer, as the trailer's electric conne
cter will be plugged into the vehicle.
To avoid system malfunctions, when not driving with a trailer, remove the
trailer hitch.
Possible faults
If a continuous bleep sounds for some seconds when the reverse gear is
engaged, 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 acci-
dents.
•
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 mo ves 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.
•
Obstacles with uniform edges and bumps may not be detected immedi-
ately by the system due to their geometry. Take special care around this type
of obstacle such as corners, recta ngular objects, etc.., these can cause
damage to the vehicle.
•
Be especially carefully when mano euvring into a corner between two
perpendicular walls. Survey 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.
•
Distant ultra-sonic sources (hammers, tyres, 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 control system (CCS)*Description
The cruise control system is able to maintain the set speed in
the range from approx. 30 km/h to 180 km/h.Once the speed setting has been saved, you may take your foot off the accel-
erator.
WARNING
It could be dangerous to use the cruise control system if it is not possible
to drive at constant speed.•
For safety reasons the cruise control system should not be used in
dense traffic, in sections with bends or where roads conditions are poor
(e.g. aquaplaning, loose chippings, slippery surfaces, snow). Risk of acci-
dent.
•
Always switch off the CCS when you have finished using it. This will
prevent you using it by mistake.
•
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 co nstant speed when descending gradi-
ents. The vehicle will accelerate under its own weight. Use the foot brake to
slow the vehicle.

Intelligent technology
168Anti-lock brake system (ABS)The anti-lock brake system prevents the wheels locking during braking
⇒ page 166.Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.EDL helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
The system will control the revolutions of the drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒page 77.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheel s of approximately 100 rpm caused by
a slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the other
driven wheel via the differential.
To prevent the disc brake of the braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. The vehicle will continue to
function normally without EDL. For this reason, the driver is not informed that
the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled down.
WARNING
•
When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may start to
spin. This could impair the vehicle's stability.
•
Always adapt your driving style to suit road conditions and the traffic
situation. Do not let the extra safety afforded by EDL tempt you into taking
any risks when driving, this can cause accidents.Caution
Modifications to the vehicle (e. g. to the engine, the brake system, running
gear or any components affecting the wh eels and tyres) could affect the oper-
ation of the EDL ⇒page 186.The traction control system (TCS)The traction control system prevents the drive wheels from spinning when the
car is accelerating ⇒page 166.
