Washer/Wiper system/Rain sensor
Rain sensor *
When the rain sensor is activated, the
windshield wiper is controlled automati-
cally, depending on the degree of
wetness of the windshield (in both snow
and rain). You do not have to be
concerned with switching the wind-
shield wiper on or off or adjusting the
wipe interval between intermittent and
full wipe. Instead, you can concentrate
fully on the traffic conditions. This is
especially important under adverse
weather conditions.
The rain sensor is positioned on the
windshield, directly ahead of the inte-
rior rearview mirror.
To activate the rain sensor:
>
From ignition key position 1, move
the lever to position 1. The wipers
travel once across the windshield,
regardless of the weather.
>
You can leave the lever permanently
in position 1. It is then only necessary
to activate the rain sensor from igni-
tion key position 1. To do this
>
give rotary dial 5 a quick turn or
>
clean the windshield 5, refer to
page
66 .
To adjust the sensitivity of the rain
sensor: turn rotary dial 5.
Deactivating the rain sensor: put lever
in position 0.
Deactivate the rain sensor when
passing through an automatic car
wash. Failure to do so could result in
damage caused by undesired wiper
activation.

The system sprays washer fluid onto
the windshield and activates the wipers
for a brief period.
If you only pull the lever briefly, the
system sprays washer fluid onto the
windshield without activating the
wipers.
Do not use the washers if there is
any danger that the fluid will
freeze on the windshield. If you do so,
your vision could be obscured. For this
reason, use an antifreeze agent. Refer
