Fig. 85 Inside the front windshield above the inside mirror: Sensitive rain sensor surface.

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 (arrows) 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.

(4) Sensor for registering light from the front
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.
There are two sensors in the interior mirror housing:
x One sensor on the side facing the interior to measure light from the rear of the vehicle A (3) or B (3).
x One sensor on the side facing the windshield to measure light from the front of the vehicle C (4).
If the ignition is switched on, the mirror automatically darkens 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.
Outside mirrors

NOTICE
x Things like trailer draw bars, thin rods, fences, trees, narrow painted vertical poles, posts, or a rear hatch that is opening may not be detected by the Park Distance Control sensors and could damage the vehicle.
x If you continue driving closer to an object that the Park Distance Control has already detected and reported, the object may disappear from the sensor range and may no longer be detected. This is especially true for low or high objects. The system will no longer sound warnings about these objects. Ignoring signals from the Park Distance Control system could result in serious damage to the vehicle.
x The sensors in the bumpers can be damaged or become misaligned in low speed impacts and parking maneuvers. Damaged or misaligned sensors cannot accurately detect or report objects that might be within range of the PDC system.
x To help make sure that the system works properly, always keep the sensors in the bumpers clean and free of snow and ice; do not cover the sensors with stickers or other objects.
x When cleaning the sensors with power washers or steam cleaners, only spray the sensors directly for a very short time, and always keep the washer nozzle at least 4 inches (10 cm) from the sensors.
x Noise from rough roads, cobblestones, other vehicles and the surrounding area, for example, can prevent the Park Distance Control system from accurately detecting and reporting people and objects that may be within range of the sensors.
x Aftermarket components such as bicycle racks can impair the function of the Park Distance Control system.
Volkswagen recommends practicing with the Park Distance Control system in a location or parking space with no traffic in order to become familiar with the system and how it works.

Operation

Fig. 145 In the front and rear bumpers: Park Distance Control system sensors.

In order to Operation (when the ignition is switched on)
Switch to the rearview camera display (if equipped):
Shift into Reverse (R).
OR: Tap the Z function key.

The indicator light in the  button ⇒ fig. 146 lights up and stays on as long as the feature is active.
Automatic activation
When the PDC is activated automatically, a mini PDC display will appear on the left-hand side of the
screen ⇒ fig. 148.
Automatic activation of the PDC when driving slowly towards an obstacle located in front of the vehicle only works when the speed falls below about 6–9 mph (10–15 km/h) for the first time. If the PDC was switched off using the  button, performing one of the following actions with the ignition switched on can automatically reactivate the PDC:
x If the vehicle accelerates to a speed greater than 6–9 mph (10–15 km/h) and then drops below that speed again.
x OR: if the selector lever is moved to Park (P) and then out of that position again.
x OR: if automatic activation is activated and deactivated in the Infotainment system menu.
Automatic activation with mini PDC display can be activated and deactivated in the Infotainment
system ⇒ Infotainment system.
When automatic activation is activated, signal chimes are sounded from a distance of about 20 inches (50 cm) from the obstacle.
WARNING
Never rely completely on the PDC for information about people and objects that might be in the way of the vehicle and could be struck by the vehicle causing serious personal injury.
x The PDC sensors have blind spots where they cannot detect people or objects.
x Always watch for people, especially small children and animals, because the sensors may not always be able to detect them.
If you hear a long beep of about 3 seconds when you first turn PDC on or the indicator light in the button starts blinking, this means there is a malfunction in the Park Distance Control system. Switch off the Park Distance Control system with the button and have it immediately checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.

Signal chimes
When the vehicle approaches an obstacle located in the range of the ultrasonic sensors, there are audible signal chimes. An intermittent signal chime means that a sufficiently short distance between the vehicle and an obstacle is detected. The shorter the distance, the shorter the intervals between the chimes. The signal chime will sound continuously if the obstacle is very close.
When there is an imminent risk of collision at the front area of the vehicle, the signal chimes beep at the front of the vehicle. When there is a risk of imminent collision at the rear area of the vehicle, the signal chimes beep at the rear of the vehicle.
If you continue to drive the vehicle closer to the obstacle despite a continuous signal chime, the system will no longer be able to measure the distance.
The intermittent signal chime volume decreases after a few seconds if the distance remains the same. The volume remains constant if the signal chime is continuous. As soon as the vehicle moves away from an obstacle again, the intermittent signal chime switches off automatically. If the vehicle moves towards an obstruction again, the intermittent signal chimes beep automatically.
Display
The graphic on the screen displays the scanned areas in several segments. The closer the vehicle drives towards an obstacle, the closer the segment will move to the vehicle in the display. The collision area has been reached at the latest when the second to last segment is displayed. Do not keep driving!

PDC menu

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 rear hatch. 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 rear hatch to help prevent unintentional opening in the car wash.
