2015 VOLKSWAGEN EOS ignition

Lights up Possible cause Proper response
Y Not enough windshield washer fluid. Refill windshield washer reservoir at the next opportunity

When the ignition is switched on, several warning and indicator lights come on briefly for a function check. They go out after a few seconds.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
Windshield wiper lever

Fig. 88 Operating the front windshield wiper.

Move the lever to the desired position ⇒ :
(F) W Pull the lever toward the steering wheel to activate the windshield washers, then release.

NOTICE
To help prevent damage to the wiper blades and the wiper motor when it is cold outside, always make sure that blades are not frozen to the windshield before operating the wipers. Using the service position can be helpful in cold weather so the wipers do not freeze to the windshield, Windshield wiper service position.
x If the ignition is switched off while the wipers are running, the wipers will continue at the same wiping speed when the ignition is switched on again. Frost, ice, snow, leaves, and other objects on the windshield can damage the wipers and the wiper motor.
x Remove snow and ice from the wipers before you begin driving.
x If the wiper blades freeze to the windshield, loosen them carefully. Volkswagen recommends using a deicing spray.
NOTICE
Never switch on the windshield wipers when the windshield is dry because the windshield can be scratched.
The windshield wipers work only if the ignition is switched on and the engine hood is closed. The windshield wipers turn off automatically when the engine hood is opened.
The intermittent wiping for the front windshield depends on the driving speed. The higher the speed, the faster the wipers move.
If the wiper blades freeze to the windshield, loosen them carefully. Volkswagen recommends using a deicing spray.
Windshield wiper functions

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.

x Wipers move into service position.
Carefully fold the wiper arms back onto the windshield before driving! Switch the ignition on and press
the windshield wiper lever down briefly ⇒ fig. 88 (E). The wiper arms move back to their original position.
Lifting the wiper blades and tilting them away from the windshield
x Put the wiper arms in service position ⇒ .
x Do not handle the wiper blades, handle the wiper arms only at the attachment above the wiper blades.
NOTICE
x To help prevent damage to the engine hood and the windshield wiper arms, lift the wiper arms away from the windshield only when they are in the service position.
x Always carefully fold the windshield wiper arms down against the windshield before driving the vehicle.
Rain sensor

Fig. 90 Windshield wiper lever: Adjusting rain sensor 1.

Fig. 91 Inside the front windshield above the inside mirror: Sensitive rain sensor surface.

Push the lever into the desired position ⇒ fig. 90:
(A) Rain sensor off (windshield wiper lever home position).
(B) Rain sensor active – automatic wiping as needed.
(1) Adjusting the sensitivity of the rain sensor:
– Move switch to the right – high sensitivity.
– Move switch to the left – low sensitivity.
After switching the ignition off and back on again, the rain sensor stays on and works again with the wiper lever in position (B).
Possible reasons for changes in the way the rain sensor works
The rain sensor may misread what is happening in the detection zone of its sensitive rain-sensor
surface ⇒ fig. 91 (arrow) and not work for a number of reasons, which include:
x Worn out wiper blades: Worn out wiper blades may leave a film of water or wiping streaks; this can cause the wipers to run longer, to wipe more often, or to wipe continuously at high speed.
x Insects: Insects hitting the sensor may trigger the wipers.
x Salt streaks: Salt streaks on the windshield from winter driving can cause wiping more often or continuously on glass that is almost dry.
x Dirt: Caked-on dust, wax, any other buildup on the windshield (lotus effect), or car-wash detergent residue can lower the rain sensor's sensitivity and cause it to react too slowly or not at all.
x Crack or chip in the windshield: If a stone hits and chips the windshield while the rain sensor is on, this will trigger a wiper cycle. After that, the rain sensor will recognize the change and recalibrate itself to respond to the sensitive surface's reduced detection zone. Depending on the size of the chip, the sensor's reaction pattern may or may not change.
WARNING
The rain sensor cannot always recognize rain and activate the wipers.
x Switch the wipers on manually when water on the windshield reduces visibility.
Clean the rain sensor's sensitive surface ⇒ fig. 91 (arrow) regularly and check the wiper blades for wear or damage.
To remove wax and coats of polish safely, we recommend using an alcohol-based windshield cleaner.

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.
