Windscreen wiper functions
Windscreen wiper performance in different situations:If the vehicle is at a stand-
still:The activated position provisionally changes
to the previous position.
During the automatic wipe:
The air conditioner comes on for approxi-
mately 30 seconds in air recirculation mode
to prevent the smell of the windscreen wash-
er fluid entering the inside the vehicle.
For the interval wipe:The intervals between wipes vary according
to the speed of the vehicle. The higher the
vehicle speed the shorter the intervals.
Heated windscreen washer jets
The heating only thaws the frozen jets, it does not thaw the water in the
washer hoses. The heated windscreen washer jets automatically adjust the
heat depending on the ambient temperature, when the ignition is switched
on.
Headlight wash/wipe system
The headlight washers/wipers clean the headlight lenses.
After the ignition is switched on, the first and every fifth time the wind-
screen washer is switched on, the headlights are also washed. Therefore,
the windscreen wiper lever should be pulled towards the steering wheel
when the dipped beam or main beam are on. Any incrusted dirt (such as in-
sects) should be cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work correctly in winter, any snow which
has got into the bumper jet supports should be cleaned away. If necessary,
remove snow with an anti-icing spray.
Note
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.
Windscreen wipers service position

142Seats and storage
Note
Read and take into account the instructions included with the roof carrier
system fitted and keep them in the vehicle.
Loading the roof carrier system
Loads can only be correctly secured when the roof carrier system is correctly
fitted ⇒ .
Maximum authorised roof load
The maximum authorised roof load is 100 kg (about 220 lbs). The roof load
includes the roof carrier system and the load being transported ⇒
.
Always check the roof carrier system weight and the weight of the load to be
transported and, if necessary, weigh them. Never exceed the maximum au-
thorised roof load.
If you are using a roof carrier with a lower weight rating, you cannot trans-
port the maximum roof load. Do not exceed the maximum weight limit for
the roof carrier given in the fitting instructions.
Distributing a load
Uniformly distribute loads and secure them correctly ⇒
.
Check attachments
After fitting the base supports and the roof carrier system, always check the
attachments after a short trip or at regular intervals.
WARNING
Exceeding the maximum authorised roof load can result in accidents
and/or vehicle damage.
● Always respect the maximum authorised weight for the roof, the max-
imum authorised weight on the axles and the total maximum authorised
weight of the vehicle.
● Never exceed the capacity of the roof carrier system even if this is
less than the maximum authorised roof load.
● Secure heavy objects towards the front and distribute the load even-
ly.
WARNING
Loose and incorrectly secured loads can fall from the roof carrier system
causing accidents and injury.
● Always use suitable ropes and straps in good condition.
● Always secure loads correctly.
Storage compartments Introduction
Storage compartments must only be used to store light or small objects.
The front central armrest compartment houses the factory-fitted AUX-IN or
multimedia (MEDIA-IN) connection sockets.
The factory-fitted CD changer is located in the left-hand storage compart-
ment of the luggage compartment.

Driving
WARNING
The counter steering assistance system combined with ESC helps the
driver to steer the vehicle in critical driving conditions. At all times, it is
the driver who steers the vehicle. The counter steering system does not
steer the vehicle.
Adjusting the steering wheel position
Fig. 128 Mechanical
steering wheel adjust-
ment
Adjust the steering wheel before your trip and only when the vehicle is sta-
tionary.
● Push the lever ⇒ Fig. 128 1
downwards.
● Adjust the steering wheel so that you can hold onto the steering wheel
with both hands on the outside of the ring at the 9 o'clock and 3 o'clock
positions and your arms slightly bent.
● Push the lever firmly upwards until it is flush to the steering column
⇒
.
WARNING
Incorrect use of the steering wheel adjustment function and an incorrect
adjustment of the steering wheel can result in severe or fatal injury.
● After adjusting the steering column, push the lever ⇒ Fig. 128 1
firmly upwards to ensure the steering wheel does not accidentally
change position while driving.
●
Never adjust the steering wheel while the vehicle is in motion. If you
need to adjust the steering wheel while the vehicle is in motion, stop
safely and make the proper adjustment.
● The adjusted steering wheel should be facing your chest and not your
face so as not to hinder the driver's front airbag protection in the event of
an accident.
● When driving, always hold the steering wheel with both hands on the
outside of the ring at the 9 o'clock and 3 o'clock positions to reduce inju-
ries when the driver's front airbag deploys.
● Never hold the steering wheel at the 12 o'clock position or in any oth-
er manner (e.g. in the centre of the steering wheel). In such cases, if the
driver's airbag deploys, you may sustain injuries to your arms, hands and
head.

Fig. 143 Parking sensor
system sensors on the
front bumper
The parking sensor system assists the driver when parking. If the vehicle is
approaching an obstacle, an intermittent audible warning is emitted. The
shorter the distance, the shorter the intervals between tones. If the vehicle
is too close to the obstacle, the audible warning becomes constant. Switching the parking sensor system on and off
●
Press the
button ⇒
Fig. 142 when the ignition is switched on.
● Automatic on: select reverse gear.
● Automatic off: drive faster than 15 km/h (9 mph).
The button lights up when the function is switched on.
Things to note regarding the parking sensor system
● The parking sensor system sometimes registers water on the sensors as
an obstacle.
● If the distance does not change, the warning signal will sound less loud-
ly after a few seconds. If the continuous signal sounds, the volume will re-
main constant.
● When the vehicle moves away from the obstacle, the beeping sound au-
tomatically switches off. On approaching the obstacle again, the beeping
sound will automatically switch back on.
● If the electronic parking brake is engaged or the selector lever is set to
P, no audible warning will be emitted.
● Your Technical Service can adjust the volume of the warning signals.
Note
If the parking sensor system is faulty, a constant audible warning will be
emitted the first time it is switched on and the button will flash. Switch the
parking sensor system off using the button and take the vehicle to a speci-
alised workshop to have the system checked as soon as possible.
