Wiper performance in different situations:
During automatic
wipe/wash:
While the washer system is working, the
Climatronic switches to recirculation for
about 30 seconds to help prevent the
washer fluid odor from entering the vehi-
cle interior.
During intermittent
wiping:
Speed-dependent interval control: The
higher the vehicle speed, the faster the
wipers move.
Heated washer nozzles
The heating thaws frozen washer nozzles, but not the fluid supply
hoses. When the ignition is switched on, the heat applied to the
washer nozzles is automatically regulated depending on the outside
air temperature.
Headlight washer system
The headlight washer system cleans the headlight glass.
If the ignition and the headlights (high or low beams) are switched on,
the headlights are cleaned the first time and every fifth time the front
windshield washers are activated. This happens only when the low or
high beams are on when the windshield wiper lever is pulled towards
the steering wheel. However, the headlights must still be washed by
hand periodically (for instance, during refueling) in order to get rid of
hard-to-remove dirt (like insect splatter).
To help make sure that the headlight cleaning system works during
winter weather, always keep the headlight washer nozzles free of
snow and remove any ice with a deicer spray before driving. Use a
deicer spray to remove any ice.
If there is something on the windshield, the wiper will try to wipe it
away. If it continues to block the wiper, the wiper will stop moving.
Remove the obstacle and switch the wiper on again.
Changing wiper blades
Lift the wiper arm(s) away from the windshield.
Press and hold the release button ⇒ fig. 172 (1).
While lifting the wiper blade in the direction of the wiper arm, pull
off the wiper blade in the direction of the arrow. This may require
moderate force.
Install a new wiper blade of same length and type onto the wiper
arm by pushing in the opposite direction of the arrow until it latches.
Carefully fold the wiper arm back down onto the windshield.
WARNING
Worn or dirty wiper blades reduce visibility and increase the
risk of accidents and severe injuries.
Always change wiper blades if they are damaged or worn,
and if they cannot clean the windows sufficiently.
NOTICE
Damaged or dirty wiper blades can scratch the windshield.
Solvents, abrasive sponges and sharp-edged objects will
damage the graphite coating on the wiper blades.
Do not clean the windows with gasoline, nail polish remover,
paint thinner or similar fluids.
To help prevent damage to the engine hood and the wind-
shield wiper arms, lift the wiper arms away from the windshield
only when they are in the service position.
