Lights and visibility
Rain sensor
The rain sensor* will only function in the intermittent wipe position. The inter-
mittent wipe function is enabled automatically when it starts to rain.
Before you reach a road speed of 6 km/h ,you will have to enable the rain
sensor manually by switching it off and back on again.
A
Use control
to set the sensitivity of the rain sensor*.
A
If you have selected a high sensitivity level for the rain sensor the windscreen
wipers will react sooner to any moisture on the windscreen.
The wiper intervals in the intermittent wipe setting are also varied automati-
cally according to the road speed (in addition to the sensitivity setting).
WARNING
•
For correct visibility and safe driving, the wiper must be in perfect
condition ⇒ page 201. Failure to do so could result in an accident.
•
The rain sensor* is only intended to assist the driver. The driver is still
obliged to manually operate the windscreen wipers as required depending
on visibility.
•
Do not use water-repellent coatings on the windscreen. In bad visibility
conditions such as light rain, low sun or when driving at night, these coat-
ings can cause increased dazzle, which is a serious safety hazard. Such
coatings can also cause the wiper blades to judder.
Caution
•
In the event of frost, check that the wiper blade has not frozen before
enabling the windscreen wipers. Should the windscreen wiper system be
enabled when the blade is frozen, this could damage it or even the wind-
screen wiper system motor.
•
Make sure you switch off the windscreen wiper system (lever in position
0) before you use an automatic car wash. This will avoid inadvertent trig-
gering of the wipers and possible damage to the wiper system.
Note
•
Check that the washer fluid reservoir is full before starting a long journey.
Fill the reservoir ⇒ page 220.
•
Worn or dirty wiper blades can cause smearing on the glass which can
also impair the effectiveness of the rain sensor*. Check the condition of wind-
screen wiper blades at regular intervals.
