the inside rear view mirror also deact i­
vates the automatic dimming f unction of
the exterior m irrors.

Wiper and washer system
Windshield wiper

Fig. 62 Wiper lever: wind shi eld w iper lever pos it ions
T he windshield wiper lever i=:> fig. 62 has the
following positions:
Intermittent wiping ~l (activating rain
sensor)*
.. Move the lever up to position (D.
.. Move the interval set switch @, to change
the intervals.
Low wiper speed
.. Move the lever up to position @.
High wiper speed
.. Move the lever up to posit ion @.
One-touch wiping
.. Move the lever to position @, when you
want to wipe the windshield
briefly.
Automatic wiper/washer
.. Pull the lever to position ® (to ward the
steering whee l) and hold .
.. Release the lever . The washer stops and the
w ipers keep going for about four seconds.
Turning off the wipers
.. Move the lever back to position @ .
The windshield w ipers and washer only work
when the ignition is turned on. If you switch
off the igni tion with the windshie ld wipe r lev­
er still in the interval wipe position and then
come back a while later and drive off, the ra in
sensor will reactivate itself after the vehicle
speed has exceeded 4 mph (6 km/h).
Th e rai n sensor* is only activated with the
wiper lever set to position
(D. When it starts
to rain, the rain senso r will a utomat ically acti­
vate the intermittent wiping mode .
To reduce the sensitivity of the sensor, move
swi tch @ down. To increase the sensitivity,
move the switc h up. The higher you adjust the
sensitivity, 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 ve-
hicle speed as well. ..,.

During brief stops, e.g. at a red light, wiper
motion 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.
A WARNING
- Wiper blades are crucial for safe driving!
Only when they are in good condition are
they able to clear the windows properly
to provide uncompromising visibility .
Worn or damaged wiper blades are a safety hazard ¢
page 5 7, Replacing
windshield wiper blades!
- The light/rain sensor* is only designed to
assist and support the driver.
It remains
entirely 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 in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter .
(I) Note
In freezing or near freezing conditions:
- Always check that the wiper blades are
not frozen to the glass before you turn
the wipers on . Loosen a wiper blade
which is frozen in place before operating
the wipers to prevent damage to the
wiper blade or the wiper motor.
- Do not use the wipers to clear a frosted window . Using the wipers as a conven­
ient ice scraper will destroy the wiper
blades.
- Before you take your vehicle to an auto­
matic car wash, make sure you have the
windshield wiper system switched off (lever in position 0), otherwise the wind­
shield wiper system could get damaged

in the car wash if it should suddenly
come on.
(0 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 wind­
shield wiper lever to any position.
- Worn or dirty windshield wiper blades
cause smearing, which can affect the op­
eration 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 deactivate the rain sensor. To re­ activate the sensor, switch off the inter­
val wiping function, then switch it back
on again.
-Applies to vehicles with light/rain sen­
sor : When the wipers are switched on
manually and in rain conditions, the au­
tomatic headlights* turn on¢

- Do not d ispose of leftover cleaning and
ca re products with household trash .
Car washes
-
The longer that deposits such as insects, bird
droppings , tree sap or road salt rema in on the
vehicle, the more the surface can be dam­
aged. High temperatures such as those
caused by s unligh t increase the corrosive ef­
fect.
Before washing, wet heavy deposits with plen­
ty of water.
Also, wash the underside of your vehicle once
road salt stops be ing used for the season .
Pressure wa shers

sure and spray ing distance . Do not aim the
spray directly at seals on side w indows, doors, the
hood, the rear lid or the convertible top or
at tires, rubber hoses, insulating material
orsensors* . Keep a distance of at least 16 in ­
ches (40 cm) .

first remove dust and large particles from
your vehicle. Insects, grease spots and finger­
prints are best removed with a special cleaner
for matte finish paint .

avoid damaging the paint surface, do not use
too much pressure.
Rinse the vehicle thoroughly with water. Then
clean using a neutra l shampoo and a soft mi ­
crofiber cloth.
