2012 VOLKSWAGEN TOUAREG sensor

Function Action
Switching the DRL back on: – Release the parking brake.
– OR: Turn the light switch to the 
position.

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 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 headlight
control (headlight switch in the !54/ position) ⇒ fig. 85, 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 / position or when the fog lights themselves have been switched on ⇒  Switching lights on and off.
Automatic headlight control !54/
Automatic headlight control is a convenience feature only and cannot always recognize all driving situations.
If the light switch is in the !54/ position, the outside vehicle lighting and the instrument lighting are
automatically switched on at dusk/nightfall and off in normal daylight in the following situations ⇒ :

Automatic activation: Automatic deactivation/change to
daytime running lights:
If the low-light sensor registers
darkness, for example when driving
through a tunnel.
If sufficient brightness is registered.
If you drive faster than about
87 mph (140 km/h) for several se-
conds.
If you drive slower than about
40 mph (65 km/h) for several se-
conds.
If the rain sensor recognizes heavy
rain and switches the windshield
wipers on.
If the windshield wipers have not
moved for several minutes.

low light sensor detects darkness. The delay period
starts once the last vehicle door or the rear hatch is
closed.

Background lighting in the outside mirrors
The background lighting in the outside mirrors lights up the area close to the doors while you are getting into or out of 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 lights stay on for about 10 seconds (lighting delay period). The “Coming home” and “Leav-ing home” features can be enabled and disabled in the Infotainment System.
If the “Coming home” feature is switched on and the driver door is opened, no acoustic warning will sound to alert that the light is still on.

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. 95 (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 cause wiping.
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 in the windshield: If a stone hits and chips the sensitive surface 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 smaller 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 sensitive area of the rain sensor 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.
