Warning and indicator lights

Radar sensors
The Side Assist radar sensors are located on the left and right side above the rear bumper ⇒ fig. 281. They cover an area of about 50 m (160 ft) behind your vehicle as well as the blind spots on the left and right vehicle side. On the left and right side of your vehicle Side Assist covers an area of about the width of one driving lane.
However, Side Assist does not recognize the exact width of the driving lanes next to your vehicle. In some cases, such as driving in the middle of 2 lanes or with very narrow lanes, this can lead to an incorrect indication. In other cases, vehicles moving on further driving lanes like the second to left lane, or even fixed objects, such as guide rails, can cause the indicator lights to light up.

NOTICE
x Things like trailer draw bars, thin rods, fences, trees, and narrow painted vertical poles or posts may not be detected by the Park Distance Control and Optical Parking System sensors and could damage the vehicle.
x If you continue driving closer to an object that the Park Distance Control and Optical Park-ing Systems have 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 sys-tem will no longer sound warnings about these objects. Ignoring signals from the Park Dis-tance Control system could result in serious damage to the vehicle.
x The sensors in the bumper 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, 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 exam-ple, can prevent the Park Distance Control system from accurately detecting and reporting people and objects that may be within range of the system 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 and the Optical Parking System in a location or parking space with no traffic in order to become familiar with the system and how it works.
Park Distance Control

Fig. 297 On the front and rear bumper: Park Distance Control system sensors.

In order to Operation
OR: If the vehicle rolls backwards.
Automatically
deactivate
the PDC:
Drive forward faster than about 5 – 10 mph (10 – 15 km/h).
OR: Shift into Reverse R.
Switch to full-
screen view:
Vehicle rolls backwards slowly.
OR: Press the lit-up button  or ∗.
OR: Tap the /03 function key ⇒ fig. 299.

The indicator light in the button  ⇒ fig. 298 comes on and stays on as long as the feature is active.
A chime sounds to tell you that the system is on. If the chime does not sound, PDC is not working. Have the system inspected by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Special considerations when using Park Distance Control
x In some cases, the Park Distance Control system interprets water and ice on the sensors as an obstacle. To prevent automatic PDC activation in these cases, you can turn Park Distance Control off
permanently in the Infotainment System ⇒  Automatic activation in the Infotainment System.
x If the distance remains the same, the warning tone volume decreases after a few seconds. If a continuous tone sounds, its volume remains the same.
x If the vehicle moves away from the obstacle, the beeping sound stops automatically. The beep turns on once more automatically if the vehicle approaches the obstacle again.
x There is no beeping when the transmission is in Park (P) or the electronic parking brake is en-gaged.
x The volume of the audible signals can be adjusted by an authorized Volkswagen dealership or an authorized Volkswagen Service Facility.
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 lasting 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.

Function key: Actions
Automatic activation of mini-OPS : If the check box in the function key is
checked =, the small screen OPS display is automatically switched on
when you slowly approach an obstacle. To switch off this feature, tap Au-
tomatic activation of mini-OPS . After deactivation, there will not be any
warning when you approach an obstacle.
Reset settings : Resets all settings to the factory settings.

When towing a trailer
On vehicles with a factory-installed trailer hitch and an electrically connected trailer, a corresponding graphic is displayed on the screen. Distance values behind the vehicles will not be displayed.
Muting the Park Distance Control volume
You can mute the PDC beeping signals by tapping the  function key on the Radio or Navigation system screen. Tap the function key again to reactivate the acoustic signals.
Muting is cancelled by switching Park Distance Control back on after it was switched off. The warning messages cannot be switched off.
If the display has been switched off manually and PDC remains active, the mute setting is also can-celled.
Switching Park Distance Control back on after it was switched off reactivates the volume. System malfunction warning signals cannot be switched off.
WARNING
Never rely completely on the OPS 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 OPS sensors have blind spots where they cannot detect persons or objects.
x Never pay so much attention to the OPS and the graphics shown on the screen that you fail to notice what is going on around you.
x Always watch for people, especially small children and animals, because the sensors may not always be able to detect them.
NOTICE
Automatic activation of OPS when approaching an obstacle works only when your speed falls below a threshold of about 5 - 10 mph (10 - 15 km/h). If you then close the display, you must either switch the ignition off and back on or exceed the speed threshold and then reduce speed to under the threshold a second time in order for it to activate automatically again.
Volkswagen recommends practice parking with Park Distance Control and the Optical Parking System on a parking lot or other place where there is little traffic to get used to how the system works.

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!
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 through a car wash.
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. Do not fold power mirrors manually!
x Lock the rear hatch to prevent unintentional opening in the car wash.
Washing with a power washer

Never use a power washer to clean the engine compartment ⇒  Cleaning the engine compartment.
WARNING
Improper use of power washers can cause serious invisible permanent damage leading to tire failure and loss of vehicle control. This can cause accidents and severe personal injury.
x Keep sufficient distance between water jet and tires. Never wash tires with a nozzle that sprays the water out in a direct stream regardless of the distance to the tire and even for a very short time.
x Never use “dirt blasters.” to clean tires. Even spraying from a relatively long distance for a very short time can do visible or invisible damage to tires.
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.
NOTICE
x Water temperature should 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 In order for Park Distance Control to work correctly, the sensors in the bumpers must be kept clean and clear of snow and ice.
x When using a power washer or steam cleaner, only spray the rear assist sensors directly for a short period of time and always keep the nozzle at least 4 inches (10 cm) from the sensor.
x Do not clean icy or snow-covered windows with a power washer.
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!

unit. Some suspension changes can, for example, increase the force levels measured by the airbag sensors and send to the electronic control unit and make the airbag system deploy in crashes in which it would not deploy if the changes had not been made. Other kinds of changes may reduce the force levels measured by the sensors and prevent the airbag from deploying when it should.
Never install leather upholstery on a vehicle that originally had cloth upholstery. Never install cloth upholstery on a vehicle that originally had leather upholstery. The weight-sensing mat for the Ad-vanced Airbag system will not work properly if different upholstery is installed on the passenger seat than the upholstery originally installed on the vehicle when it was originally manufactured.
WARNING
Changing the vehicle's suspension including use of unapproved tire-rim combinations can change airbag performance and increase the risk of serious personal injury in a crash.
x Never install suspension components that do not have the same performance characteris-tics as the components originally installed on your vehicle.
x Never use tire-rim combinations that have not been approved by Volkswagen.
WARNING
Leaving the optional safety belt extender attached to the safety belt buckle on the front pas-senger seat when the safety belt is not being used will prevent the Advanced Airbag System from working properly and can increase the risk of serious personal injury in a collision.
x Leaving the extender attached to the safety belt buckle when the front seat is occupied and the safety belt is not being used will signal to the airbag control unit that the front pas-senger seat is occupied and that the safety belt is being used. The electronic control unit for the airbag system will then receive incorrect information that will
– cause the safety belt pretensioner to deploy unnecessarily in collisions and
– cause the front passenger airbag to deploy later in collisions in which the front airbag would otherwise be triggered earlier to help protect an unrestrained front seat passenger.
x Always remove the safety belt extender when it is not needed and stow it safely.
x Never use the safety belt extender to secure a child restraint.
WARNING
Items stored between the safety belt buckle and the center console can cause safety belt buckle to send the wrong information to the airbag control unit and prevent the Advanced Airbag System from working properly.
x Always make sure that nothing can interfere with the safety belt buckles and that they are not obstructed.
