Changes in the response of the rain/light sensor
Possible causes for faults and misinterpretations relating to the sensitive surface of the rain/light
sensor ⇒ Vehicle overviews include:
•Damaged wiper blades: a film of water or smears caused by damaged wiper blades can
increase the time the wipers are switched on, can shorten the length of the intervals between
wipes or cause the wipers to run quickly and continuously.
•Insects: insects hitting the windscreen surface can cause the wipers to be activated.
•Salt deposits: in winter, salt deposits on the windscreen can cause the wipers to continue to
wipe the windscreen when it is almost dry.
•Soiling: dry dust, wax, windscreen coatings (lotus effectyf R U G H W H U J H Q W G H S R V L W V I U R P D Q

slowly, or prevent it from reacting at all. Clean the sensitive surface of the rain/light sensor
⇒ Caring for and cleaning the vehicle exterior at regular intervals and inspect the wiper blades
for damage.
•Crack in the windscreen: a wipe cycle will be triggered if the rain/light sensor is on when the
windscreen is impacted by a stone. The rain/light sensor will then register the reduction in
sensitivity of the surfaces and adjust accordingly. The size of the crack can affect the way in
which the rain/light sensor activates the wipers.
We recommend that you use an alcohol-based glass cleaner to remove wax and polish.
The wipers will try to wipe away any obstacles that are on the windscreen. The wipers will
stop moving if the obstacle blocks their path. Remove the obstacle and switch the wipers back on
again.
Mirrors
Introduction
This chapter contains information on the followingsubjects:
⇒ Interior mirror
⇒ Exterior mirrors
You can use the exterior mirrors and the interior mirror to observe traffic behind you and adjust
driving style accordingly.
For safety reasons it is important that the driver positions the exterior and interior mirrors correctly
before starting a journey ⇒.
Looking in the exterior mirrors and the interior mirror does not allow the driver to see the entire side
and rear area of the vehicle. The area that cannot be seen is known as the blind spot. There may
be objects and other road users in the blind spot.
Adjusting the exterior and interior mirrors while driving may cause the driver to become
distracted. This can lead to accidents and serious injuries.
•Exterior and interior mirrors should only be adjusted when the vehicle is stationary.
•When parking, changing lane, or performing an overtaking or turning manoeuvre,
always pay careful attention to the area around the vehicle as objects and other road
users may be located in the blind spot.
•Always ensure that the mirrors are positioned correctly and that the rear view is not
restricted by ice, snow, condensation or any other objects.
