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.

Windshield wipers and washer

Page 118 of 381


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.

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.

Opening the engine hood
x Before you open the hood, make sure that the windshield wiper arms are resting on the windshield
⇒ .
x Open the driver door and pull the inside hood release lever in the direction of the arrow ⇒ fig. 150.
The engine hood is released from its latch by a spring ⇒ .
x Push the outside hood release lever ⇒ fig. 151 (arrow) and lift the hood all the way up. A gas-filled strut will hold the hood up.
Closing the engine hood
x Pull the hood down to overcome the resistance of the gas-pressure strut ⇒ .
x Lower the engine hood by hand until it is about 1 ft. (30 cm) above its latch and then let it drop into place to latch it. Do not push down on it afterwards!
If the hood does not close completely, open it again and close it properly.
When the hood is properly closed, you can see that it fits flush with the other body parts. The display
in the instrument cluster no longer indicates that the engine hood is open ⇒ page 350, Display.
WARNING
If the hood is not closed properly, it could fly up and block your view while you are driving. This can lead to a crash and serious personal injuries.
x After closing the engine hood, check that the hood release lever is properly latched into the hood latch. The engine hood must be flush with the surrounding auto body parts.
x If you ever notice that the hood latch is not properly secured when the vehicle is moving, stop at once and close it.
x Never let anyone get in the way of the hood when closing it.
NOTICE
x Make sure the windshield wipers are switched off and the windshield wiper arms are resting on the windshield before you open the hood. Otherwise, the windshield wipers and the hood may be damaged.
x Always put the windshield wiper arms down against the windshield before driving the vehicle.
NOTICE
Before opening or closing the engine hood, make sure there is enough room to do so, for example when the vehicle is in a garage.

Check all wiper blades regularly. Wiper blades that grab and squeak must be replaced if worn or
damaged and cleaned if dirty ⇒ .
Replace worn or damaged wiper blades immediately. Replacement blades may be purchased from any authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Lifting and tilting windshield wiper arms
Move the wiper arms to the service position before lifting them away from the windshield ⇒ page 198, Windshield wipers and washer.
It is not possible to lift the wiper arms away from the windshield when they are not in the service position.
When lifting or replacing a wiper blade on a window, grip it only by its mounting and not by the blade itself.
Cleaning the wiper blades
x Lift the wiper arm(s) away from the windshield.
x Using a soft cloth, carefully remove dust and dirt from the wiper blades.
x If the blades are very dirty, carefully clean them with a sponge or cloth ⇒ .
x Carefully fold the wiper arm back down onto the windshield.
Changing wiper blades
x Lift the wiper arm(s) away from the windshield.
x Press and hold the release button ⇒ fig. 159 (1).
x 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.
x 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.
x 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.
x Always change wiper blades if they are damaged or worn, and if they cannot clean the windows sufficiently.
NOTICE
x Damaged or dirty wiper blades can scratch the windshield.
x Solvents, abrasive sponges and sharp-edged objects will damage the graphite coating on the wiper blades.
x Do not clean the windows with gasoline, nail polish remover, paint thinner or similar fluids.
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.
