in the interval wipe position and then come back
a while later and drive off, the rain sensor will re-
activate itself after the vehicle speed has exceed-
ed 4 mph (6 km/h).
The rain sensor* is only activated with the wiper
lever set to position (!) . When it starts to rain,
the rain sensor will automatically activate the in-
termittent wiping mode.
To reduce the sensitivity of the sensor, move
switch @ down. To increase the sensitivity, move
the switch up. The higher you adjust the sensitivi-
ty, the faster the sensor will react when it senses
moisture on the windshield. The pauses between
wiper turns depend not only on the sensitivity
setting, but on the vehicle speed as well.
During brief stops, e.g. at a red light, wiper mo-
tion will automatically be reduced to the next
lower speed. Wipers already turning at low speed
change to intermittent wiping .
When the ignition is turned on, the washer jets
are heated.

WARNING
- Wiper blades are crucial for safe driving! On-
ly when they are in good condition are they
able to clear the windows properly to pro-
vide uncompromising visibility. Worn or
damaged wiper blades are a safety hazard

blades!
- The light/rain sensor* is only designed to as-
sist and support the driver. It remains en-
tirely the driver's responsibility to monitor
outside weather conditions and to manually
activate the wipers as soon as rain or drizzle
reduces visibility through the windshield .
- The windshield must not be treated with
water-repellent materials. They can increase
glare under poor visibility conditions such as
wetness, darkness, or when the sun is low
on the horizon . In addition, they can cause
the windshield wipers to chatter.

Note
In freezing or near freezing conditions:
52
- Always check that the wiper blades are not
frozen to the glass before you turn the wip-
ers on. Loosen a wiper blade which is frozen
in place before operating the wipers to pre-
vent damage to the wiper blade or the wiper
motor .
- Do not use the wipers to clear a frosted win-
dow. Using the wipers as a convenient ice
scraper will destroy the wiper blades.
- Before you take your vehicle to an automatic
car wash, make sure you have the wind-
shield wiper system switched off (lever in
position 0), otherwise the windshield wiper
system could get damaged in the car wash if
it should suddenly come on.

Tips
- The windshield wipers are switched off
when the ignition is turned off. Activate the
windshield wipers after the ignition is
switched back on by moving the windshield
wiper lever to any position.
- Worn or dirty windshield wiper blades cause
smearing, which can affect the operation of
the light/rain sensor*. Check the condition
of your windshield wiper blades regularly.
- The rain sensor is part of the interval wiping
system. Turning off the ignition will also de-
activate the rain sensor. To reactivate the
sensor, switch off the interval wiping func-
tion, then switch it back on again.
- Applies to vehicles with light/rain sensor:
When the wipers are switched on manually
and in rain conditions, the automatic head-
lights* turn on <=> page 46, Lights or off dur-
ing the day when the wipers are no longer
operating. The automatic headlights* func-
tion is available in this case only when the
light switch is in the "AUTO" position
<=> page 46, fig. 55.
- Make sure the washer fluid reservoir in the
engine compartment is topped off before
going on a long trip. Look up <=> page 168
for checking and filling the washer contain-
er.
- The wipers only operate with the hood com-
pletely closed.
