Rain sensor*
The rain sensor controls the frequency of the windscreen
wiper intervals, depending on the amount of rain.
Switching on the rain sensor
– Move the windscreen wiper lever into position ⇒fig. 83 .
– Move the control to the left or right to set the sensitivity of the rain sensor. Switch to the right - high sensitivity. Switch to the
left - low sensitivityThe 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 switching
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.

Tips and Maintenance
Te c h n i c a l D a t a
Parking
The handbrake should always be firmly applied when the
vehicle is parked.Always note the following points when parking the vehicle:
– Use the foot brake to stop the vehicle.
–Apply the handbrake.
– The first gear should also be selected.
– Switch off the engine and remove the key from the ignition lock.
Turn the steering wheel slightly to engage the steering lock.
– Always take you car keys with you when you leave the vehicle ⇒ .Additional notes on parking the vehicle on gradients:
Turn the steering wheel so that the vehicle would roll against the kerb if it did
start to roll.•
If the vehicle is facing downhill, turn the front wheels so that they point
towards the kerb.
•
If the vehicle is facing uphill , turn the front wheels so that they point away
from the kerb .
•
Secure the vehicle as normal by applying the handbrake firmly and
selecting first gear.
WARNING
•
Take measures to reduce the risk of injury when you leave your vehicle
unattended.
•
Never park where the hot exhaust system could ignite inflammable
materials, such as dry grass, low bushes, spilt fuel etc.
•
Never allow vehicle occupants to remain in the vehicle when it is
locked. They would be unable to open the vehicle from the inside, and
could become trapped in the vehicle in an emergency. In the event of an
emergency, locked doors will delay assistance to occupants.
•
Never leave children unsupervised in the vehicle. They could set the
vehicle in motion, for example, by releasing the handbrake or the gear
lever / selector lever.
•
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 mWARNING (continued)

Driving
164Activation
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 connecter 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 acou stic 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 at tention 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 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.
•
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, rectangu lar objects, etc.., these can cause
damage to the vehicle.
• Be es pecially ca reful when manoeuvring 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 repl ace 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.

Intelligent technology
172Anti-lock brake system (ABS)The anti-lock brake system prevents the wheels locking during braking
⇒ page 170.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 78.
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 191.The traction control system (TCS)The traction control system prevents the drive wheels from spinning when the
car is accelerating ⇒page 170.
