2008 VOLKSWAGEN EOS Fig. 98

When you move the selector lever to Reverse (R), the static cornering lights on both sides of the vehicle may come on so that you can see the area around the vehicle better when backing up.
The static cornering lights work only when the headlights are on. If you are using automatic headlight
control (headlight switch in the AUT O position ⇒ fig. 83), they work only when the headlights have been automatically switched on. The static cornering lights do not come on when the headlight switch is in the O position or when the fog lights themselves have been switched on, Switching lights on and off.
Automatic headlight control (AUTO)
Automatic headlight control is a convenience feature only and cannot always recognize all lighting and driving situations.
If the light switch is in the AUT O position, both vehicle lighting and instrument and switch lighting are
automatically switched on and off in the following situations ⇒ :

Automatic activation: Automatic deactivation:
If the low-light sensor registers darkness, for example when driving through a tunnel. If sufficient brightness is registered.
If the rain sensor recognizes rain and switches the windshield wipers on. If the windshield wipers have not moved for several minutes.
Adaptive Front Lighting System (AFS)
The Adaptive Front Lighting System works only with the low beams switched on and only at speeds above about 6 mph (10 km/h). The swivel-mounted lamps automatically improve road illumination during cornering.
On vehicles equipped with the Adaptive Front Lighting System, the feature is switched on and off via the Assistants menu in the instrument cluster display, Volkswagen Information System .
WARNING
Crashes and other accidents can happen when you cannot see the road ahead and when you cannot be seen by other motorists.
x Never use daytime running lights (DRL) to see where you are going. DRL are not bright enough to light up the roadway and be seen by other motorists. You will not be able to see far enough ahead for safety, especially at dusk or when it is dark. Always switch on the low-beam headlights at dusk or when it is dark.
x The taillights do not come on when the daytime running lights are switched on. A vehicle without taillights on cannot be seen by others in bad weather, at dusk, or when it is dark.
x If automatic headlight control (AUTO) is switched on, the low-beam headlights still may not be switched on in fog or heavy rain. You have to switch on the low-beam headlights yourself.
In cool or humid weather, the insides of the headlights, the rear lights, and turn signals can temporarily fog up. This is normal and does not affect the service life of the vehicle's lighting system.
“Coming home” and “Leaving home” feature (orientation lighting)

“Coming home” Action
Switch on: – Switch off the ignition. – Operate the headlight flasher for about 1 second The “Coming home” lighting is switched on when the driver door is open. The delay period starts once the last vehicle door or the luggage compartment lid is closed.
Switch off: – Automatically after delay period is over. – Automatically, if a vehicle door or the luggage compartment lid is still open about 30 seconds after activation. – Turn light switch to the O position. – Switch the ignition on.

“Leaving home” Action
Switch on: – Unlock the vehicle if the light switch is in the AUT O position and the low-light sensor registers darkness.
Switch off: – Automatically after preset delay period is over. – Lock the vehicle. – Turn the light switch to the O position. – Switch the ignition on.
Background lighting in the outside mirrors
The background lighting in the outside mirrors illuminates the area near the doors when entering and exiting the vehicle. It is switched on when the vehicle is unlocked, a vehicle door is opened, or the “Coming home” or “Leaving home” feature is activated. If the vehicle is equipped with a light sensor, the background lighting in the outside mirrors is only switched on in darkness.
The delay period can be adjusted in 10 second intervals and the function can be switched on and off in the Lights & Vision menu, Volkswagen Information System.
If the “Coming home” feature is switched on and the driver door is opened, no warning chime will sound to alert you that the lights are still on.

opportunity ⇒ page 204.
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.

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

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

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. 90 (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 (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.
Checking and refilling windshield washer fluid

Fig. 91 In the engine compartment: Cap of the windshield washer fluid reservoir.

WARNING
Auto-dimming mirrors contain an electrolyte fluid which can leak if the mirror glass is broken. Electrolyte fluid can irritate the skin, eyes, and respiratory system.
x Repeated or prolonged exposure to electrolyte fluid can irritate the respiratory system, especially among people with asthma or other respiratory conditions. Get fresh air immediately by leaving the vehicle or, if that is not possible, open windows and doors all the way.
x If electrolyte fluid gets into the eyes, flush them thoroughly with large amounts of clean water for at least 15 minutes; medical attention is recommended.
x If electrolyte fluid contacts skin, flush affected area with clean water for at least 15 minutes and then wash affected area with soap and water; medical attention is recommended. Thoroughly wash affected clothing and shoes before reuse.
x If swallowed, and the person is conscious, rinse mouth with water for at least 15 minutes. Get medical attention immediately. Do not induce vomiting unless instructed to do so by a medical professional.
NOTICE
Broken glass in the auto-dimming mirrors can cause electrolyte fluid leakage. Liquid electrolyte leaked from a broken mirror glass will damage any plastic surfaces it comes in contact with. Clean up spilled electrolyte fluid immediately with clear water and a sponge.
