Daytime running lights (DRL)
Separate lamps are installed in the headlights or in the front bumper for the daytime running lights (DRL).
The daytime running lights are switched on whenever the ignition is switched on and the light switch is in position / or !54/.
When the daytime running lights are switched on, only these separate lamps come on ⇒ .
If the light switch is in position !54/, a low-light sensor switches the low beams as well as the instru-ment and switch lighting on and off automatically.
Daytime running lights (DRL) parking feature
Some models are equipped with a daytime running lights (DRL) parking feature that switches the daytime running lights off when the parking brake is engaged and the ignition is switched on.

Function Action
Switching the DRL off: – Switch the ignition on. – Turn the light switch to the / position. – Set the parking brake.
Switching the DRL back on: – Release the parking brake.

Static cornering lights
Your vehicle may have fog lights under the front bumper, which on some models are also static cor-nering lights. On some models the static cornering lights may be integrated in the headlights. At speeds below about 25 mph (40 km/h), the light on one side of the vehicle will come on automatically when you turn a corner. If you turn to the right, the right fog light comes on; turn left and the left fog light comes on. The light dims and goes out when the steering wheel is straightened out again.
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 headlights
(headlight switch in the !54/ position ⇒ fig. 80), they work only when the headlights have been auto-matically switched on. The static cornering lights do not come on when the headlight switch is in the /
position or when the fog lights themselves have been switched on ⇒  Switching lights on and off.
Automatic headlights (!54/)
Your vehicle may be equipped with automatic headlights (!54/), which are a convenience feature only and cannot always recognize all lighting and driving situations.
If the light switch is in the !54/ 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.

WARNING
The Forward Collision Warning system technology cannot overcome the laws of physics and system-related limits. The driver is always responsible for braking in time. If the Forward Collision Warning system issues a warning, immediately apply the brake to slow the vehicle down or avoid the obstacle, depending on the traffic situation.
x Always adjust your speed and driving style to road, traffic, weather, and visibility condi-tions.
x The Forward Collision Warning system cannot prevent accidents and serious injuries on its own.
x The Forward Collision Warning system can issue unnecessary warnings in certain com-plex driving situations, for example, at traffic islands.
x The Forward Collision Warning system can issue unnecessary warnings when its function is impaired, for example, if the radar sensor is dirty or if the position of the radar sensor has been changed.
x The Forward Collision Warning system does not react to people, animals, or vehicles crossing or approaching in the same lane.
x Always be prepared to take full control of the vehicle at all times.
Deactivate the Forward Collision Warning system if it does not work as described in this chapter, for example, if multiple unwanted warnings occur. Have the system checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Displays

Fig. 147 In the instrument cluster display: Distance warning.

Clean the wheels and under the door sills last. Use a different sponge or wash mitt.
WARNING
After the vehicle has been washed, the wet brakes or, in winter, brake discs or pads coated with ice, react slower and need longer stopping distances.
x Always dry the brakes and clean off any ice coatings with a few careful applications of the brake. Make sure not to endanger other motorists or cyclists or disobey legal requirements.
CAUTION
Sharp edges under the vehicle can cut exposed skin.
x Always protect your hands and arms from cuts on sharp metal edges when cleaning the underbody, the inside of the wheel housings, etc.
NOTICE
x The water temperature must not be more than +140 °F (+60 °C).
x To help prevent damage to the paint, do not wash the vehicle in direct sunlight.
x Do not use insect sponges, abrasive kitchen sponges or similar things to clean the vehicle. These can damage the paint finish.
x Never clean headlights with a dry cloth or sponge. Always use a wet cloth or sponge. For best results use soapy water.
x When washing or rinsing the vehicle in cold weather, do not let water get into the lock cylinders or point the hose at gaps around the doors, hood, or luggage compartment lid. The water could freeze on the locks and seals and make it difficult to open the vehicle!
x When outside temperatures are low, wipe the rubber seals and their contact surfaces dry to help prevent freezing.
NOTICE
To help prevent vehicle damage in a car wash:
x Compare the vehicle track width with the dimensions of the guide rails in the car wash to help prevent damage to wheel rims and tires!
x Switch off the rain sensor before driving the vehicle through a car wash ⇒  Rain sensor.
x Make sure there is enough clearance for the height and width of the vehicle.
x To help prevent paint damage to the engine hood, place wiper blades against the windshield after they have dried. Do not let them snap back into place.
x Fold the outside mirrors toward the vehicle body.
x Lock the luggage compartment lid to help prevent unintentional opening in the car wash.
