Activation
– It is automatically turned on with the anti-theft alarm, when the
vehicle is locked mechanically with the key and when the but-
ton
on the remote control is used.
Deactivation
– Press the button
on the remote control twice. Only the volu-
metric sensor is deactivated. The alarm system remains activa-
ted.
WARNING
● The Safe security system remains deactivated if the volumetric sen-
sor is deactivated.
● For those vehicles in which a separation screen is fitted, the alarm
will not function correctly due to interference with the sensor.
Note
● If the alarm has been triggered by the volumetric sensor, this will be in-
dicated by a flashing of the indicator on the driver door. This flashing will be
different to that for an activated alarm.

● If you are towing a trailer equipped with a rear fog light on a vehicle with
a factory-fitted towing bracket, the rear fog light on the vehicle will automat-
ically be switched off.
● The use of the lighting described here is subject to the relevant statutory
requirements.
● Depending on weather conditions (very cold or wet), the front and tail
lights and the turn signals may be temporarily misted. This has no influence
on the useful life of the lighting system. The lights will soon demist when
they are switched on.

ing
Activation
– Rotate the switch to the position “Auto”, this indication will
light up.
Deactivation
– Turn the light switch to 0. Automatic lighting
If automatic headlight control is switched on, dipped beam headlights are
automatically switched on by a photosensor if you drive into a tunnel, for
example.
The rain sensor switches on the dipped beam headlights when the wind-
screen wipers have been operating continuously for a few seconds and it
switches the lights off when the continuous or intermittent wipe is switched
off for some minutes
⇒ page 126.
When the automatic dipped light control is connected but the dipped lights
are off, the warning lamp lights up on the light control ⇒ fig. 72. If the
automatic control switches on the dipped lights, the instrument and control
lighting is also switched on.
WARNING
● Even if the automatic headlight control is switched on, the dipped
headlights will not be switched on with fog. Therefore, the dipped beam
must be switched on manually.
Note
● For those vehicles with the automatic headlight system, when the key is
removed from the ignition, the acoustic signal will only sound if the light
control is in the position or if the vehicle is not fitted with the coming
home function.
● If the daylight driving automatic light function is switched on, the fog
lights or rear fog light cannot be switched on in addition.
● The use of the lighting described here is subject to the relevant statutory
requirements.
● Do not put stickers on the windscreen in front of the sensor. This may
cause disruptions or faults in the automatic lighting system.
● To avoid damage to the tail lights, the lights mounted on the tailgate go
off when the tailgate is opened (depending on the country).

Coming home / leaving home function*
The Coming Home function is controlled manually. The Leav-
ing Home function is controlled with a photosensor.
If the Coming Home or Leaving Home function is connected, the front side
and dipped lights, the tail lights and the number plate light will light up to
provide assistance.
Coming home function
The Coming Home function is activated by switching off the ignition and
briefly flashing the lights. When the driver door is opened, the Coming
Home lighting comes on. If the driver door is already open when the lights
are flashed briefly, the Coming Home lighting comes on immediately.
When the last door of the vehicle or the tailgate is closed, the Coming Home
function starts and the switching off the headlights is delayed.
The Coming Home lighting switches off in the following cases:
● On completion of the time period established for the delay in switching
off the lights after all the vehicle doors and the tailgate have been closed.
● If, 30 seconds after being connected, any doors or the tailgate remain
open.
● If the light switch is turned to position .
● If the ignition is switched on.
Leaving home function
The Leaving Home function is activated when the vehicle is unlocked if: ●
the light control is in position and
● the photosensor detects “darkness”.
The Leaving Home lighting switches off in the following cases:
● If the time period for the delay in switching off the headlights has ended
● If the vehicle is locked again.
● If the light switch is turned to position .
● If the ignition is switched on.
Note
The setting for the delay in switching off the headlights in the Coming Home
and Leaving Home function can be changed or the function can be connec-
ted or disconnected in the menu Lights and visibility ⇒ page 75.
● If the ignition key is removed while the lights are on, and the lights are
flashed briefly and the driver door opened, no acoustic signal is heard, as
when the Coming Home function is on, the lights are automatically switched
off after a period of time (except when the light switch is in position or
.

● When the “intermittent wipe function” is on, the intervals are directly
proportional to the speed. This way, the higher the vehicle speed the short-
er 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 ob-
stacle 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 (hori-
zontal).
● The heat output of the heated jets is controlled automatically when the
ignition is switched on, depending upon the outside temperature.
Rain sensor*
The rain sensor controls the frequency of the windscreen
wiper intervals, depending on the amount of rain.

Fig. 86 Windscreen wip-
er lever
Switching on the rain sensor
– Move the windscreen wiper lever into position 1
⇒ fig. 86
– Move the control A
to the left or right to set the sensitivity of
the rain sensor. Control to the right: highly sensitive. Control to
the left: less sensitive.
The rain sensor is part of the interval wipe function. You will have to switch
the rain sensor back on if you switch off the ignition. This is done by switch-
ing the wiper intermittent function off and back on.
Note
● Do not put stickers on the windscreen in front of the sensor. This may
cause sensor disruption or faults.

Parking aid acoustic 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 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: 0.8 m
● middle of the rear bumper: 1.5 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.
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 25 cm, a continuous signal sounds (stop
signal). The driver should not reverse any further.
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.
183
Driving
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.
● 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
The ASR (TCS) is connected automatically when the engine starts. If neces-
sary, it may be turned on or off pushing the button on the centre console.
When the ASR (TCS) is disconnected, the warning lamp
OFF
lights up. The
TCS should normally be left on. Only in exceptional circumstances, when the
slipping of the wheels is required, should it be disconnected, 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
● Remember that the ASR (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 ASR (TCS)
tempt you into taking any risks when driving.
CAUTION
● To ensure that the ASR (TCS) functions correctly, all four wheels must be
fitted 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 ASR (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 ESC (ESP) sensors and signals, the XDS system is able to de-
tect and correct this effect.
Through the ESC (ESP), the XDS brakes the inner wheel, thereby counteract-
ing the excess drive torque in this wheel. This means that the driver's de-
sired trajectory is much more precise,
The XDS system operates in combination with the ESC (ESP) and is always
active, even when the traction control ASR (TCS) is disconnected.
Electronic Stability Control ESC (ESP) *
General notes
The Electronic Stability Control increases the vehicle's stabil-
ity on the road. The Electronic Stability Control helps reduce the danger of skidding.
The Electronic Stability Control ESC (ESP) includes the ABS, EDL, ASR (TCS)
and Steering manoeuvre recommendations.
