Wiper performance in different situations:
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.
Windshield wiper service position
Fig. 89 Windshield wiper in service position.
The self-dimming feature can be switched on and off with the switch on the inside mirror (2) A or (2) B. When self-dimming is activated, the indicator light (1) is on.
If the ignition is switched on, the sensor (3) automatically darkens the inside mirror depending on the amount of light shining into the vehicle from the rear.
The self-dimming feature is deactivated when you shift the transmission into reverse or switch on the interior lights or the reading light.
Do not attach external navigation devices to the windshield or in the vicinity of the self-dimming inside
mirror ⇒ .
WARNING
The illuminated display on an external navigation device can cause the self-dimming inside mirror to malfunction, which can result in crashes and serious injuries.
x Malfunctions in the self-dimming function can result in the inside mirror being unable to evaluate the exact distance of vehicles in the rear or other objects.
If the light striking the sensor is filtered or blocked (such as by a sunshade), the self-dimming inside mirror will not work properly or may not work at all.
When the CSC roof is down, the self-dimming inside mirror may darken under certain lighting conditions even though this is unnecessary. Turn off the self-dimming feature if necessary.
