Washing the vehicle

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.
Washing with a power washer

Make sure there is enough distance to soft materials such as rubber hoses or insulating material as well as the sensors of the Park Distance Control system (if equipped). The Park Distance Control
system sensors can be found in the rear and, if applicable, front bumper ⇒ .
Make sure there is enough distance to soft materials such as rubber hoses or insulating material.
Never use concentrated jet nozzles or so-called dirt blasters ⇒ .
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 rear bumper must be kept clean and clear of snow and ice.
x When using a power washer or steam cleaner, only spray the 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!
Cleaning windows and outside mirrors

Use window cleaner or a silicone remover to remove rubber, oil, grease and silicone deposits ⇒ .
Removing wax residue
Automatic car washes and vehicle care products can leave a wax residue on all glass surfaces. These wax residues can only be removed with special cleaners or cleaning cloths. Wax residue left on the windshield can cause the windshield wipers to grab and squeak instead of gliding smoothly. We recommend that after every car wash you remove any wax residue left on the windshield with a window cleaning cloth/chamois G 052 522 A1 or equivalent.
Windshield wiper squeak and grab can be reduced by filling the windshield washer fluid tank with a wiper fluid containing wax-removing agents. Make sure to maintain the proper mixing ratio when
refilling the washer fluid tank. Grease-removing cleaning agents cannot remove wax residue ⇒ .
Windshield cleaners, special cleaners, and cleaning cloths are available from your authorized Volkswagen dealer and authorized Volkswagen Service Facility.
Removing snow
Remove snow from all windows and outside mirrors with an appropriate brush.
Removing ice
The best way to remove ice is with a deicer spray. When using an ice scraper always scrape in one direction, never back and forth. Dirt can scratch the glass when moving the scraper backward.
WARNING
Dirty or fogged up windows reduce visibility and increase the risk of accidents and severe injuries.
x Don't drive until you have clear visibility through all windows.
x Remove ice, snow and condensation from all inside and outside window surfaces.
NOTICE
x Never mix recommended cleaning agents with other cleaning agents in the windshield washer reservoir. If you do, this could cause sediments or other by-products that can clog the windshield washer nozzles.
x Never use warm or hot water to remove snow and ice from windows and mirrors. This could cause the glass to crack!
x The heating elements for the rear defroster are on the inside of the rear window. Do not put stickers over the heating elements on the inside of the rear window and never clean the inside of the windows with corrosive or acidic cleaning agents or other chemicals that could damage the heating elements.
x Antennas installed on the insides of windows can be damaged by abrasive objects or by corrosive or acidic cleaning agents or other chemicals. Do not place any stickers on the windshield-integrated antenna and never clean the antenna with corrosive or acidic cleaning agents or other chemicals.
