Rain sensor*
The rain sensor controls the frequency of the windscreen wiper intervals,
depending on the amount of rain Ÿ. The sensitivity of the rain sensor can
be adjusted manually. Manual wipe Ÿpage 125Move the lever to the required position Ÿfig. 75:
Rain sensor off.
Rain sensor on; automatic wipe if necessary.
Setting sensitivity level of rain sensor
Set control to the right: highly sensitive.
Set control to the left: less sensitive.
When the ignition is switched off and then back on, the rain sensor stays on
and starts operating again when the windscreen wipers are in position
and the vehicle is travelling at more than 4 km/h (2 mph).
Rain sensor modified behaviour
Possible causes of faults and mistaken readings on the sensitive surface
Ÿfig. 76 of the rain sensor include:
xDamaged blades: A film of water on the damaged blades may lengthen
the activation time, reduce the washing intervals or result in a fast and contin-
uous wipe.
xInsects: insects on the sensor may trigger the windscreen wipers.
xSalt on roads: in winter, salt spread in the roads may cause an extra long
wipe when the windscreen is almost dry.
xDirt: dry dust, wax, coating on glass (Lotus effect) or traces of detergent
(car wash) may reduce the effectiveness of the rain sensor or make it react
more slowly, later or not at all.
xCracked windscreen: the impact of a stone will trigger a single wipe cycle
with the rain sensor on. Next the rain sensor detects the reduction in the
sensitive surface area and adapts accordingly. The behaviour of the sensor
will vary with the size of the damage caused by the stone.
WARNING
The rain sensor may not detect enough rain to switch on the wipers.
xIf necessary, switch on the wipers manually when water on the wind-
screen obstructs visibility.

Safety FirstOperating instructionsPractical tipsTe c h n i c a l D a t a Replacing the remote control battery
When the light Ÿpage 188, fig. 132 on the remote control does not
come on when the button is pressed, the remote control battery should soon
be replaced.
The battery is located beneath a cover on the back of the remote control. Turn
the slot to the left using a flat, blunt object (e.g. a coin). When changing the
battery, use another battery of the same model and observe the polarity when
fitting it Ÿ.
Range
The receiver is in the interior of the vehicle. The remote control, when fitted
with new batteries, has a range of several hundred metres. Obstacles
between the remote control and the vehicle, bad weather conditions and
discharged batteries can considerably reduce the range of the remote control.
An optimum range is obtained by keeping the remote control vertical, with
the aerial Ÿpage 188, fig. 132 pointing upwards. When doing so, do not
cover the aerial with your fingers or with the palm of your hand.
There must be a minimum distance of two metres between the remote control
and the vehicle.
Caution
xThe radiofrequency remote control contains electronic components.
Therefore, avoid getting the remote control wet and from being knocked and
protect it from direct sunlight.
xUse of inappropriate batteries may damage the remote control. For this
reason, always replace the dead battery with another of the same voltage,
size and specifications.
For the sake of the environment
Please dispose of old batteries so that they do not harm the environment.
For the sake of the environment
The remote control battery may contain perchlorate. Observe the legal
requirements for their disposal.
Programming the auxiliary heater
The heater or ventilation inside the vehicle can be programmed for a certain
period.
Before programming, check that the day is correctly set in the Auxiliary
heater - day of the week menu Ÿ.
Enabling the Auxiliary heater menu on the instrument panel
xFrom the main menu, select the Auxiliary heater submenu and press the
button on the windscreen wiper lever.
xALTERNATIVELY: press the or arrow buttons on the multi-function
steering wheel until the Auxiliary heater menu is displayed.
a)Within its range, the remote control might not receive the signal sent by the vehicle
receiver. In this case, the remote control will send an error message despite the aux-
iliary heater being on or off. Come closer to the vehicle and press the corresponding
button on the remote control once again.
