WARNING
To reduce the risk of serious personal injury when starting and running the vehicle's engine:
x Never start the engine or let it run in a confined or enclosed area. Engine exhaust contains carbon monoxide, a poisonous, colorless, and odorless gas. Carbon monoxide can cause unconsciousness and death.
x Never start the engine or let it run if oil, fuel, or other flammable substances are under, around, or have leaked from the vehicle, for example, due to vehicle damage.
x Never leave the vehicle unattended with the engine running, especially when it is in gear. The vehicle could move suddenly or some other unexpected event could occur, resulting in property damage, fire, or personal injury.
x Never use starting assist fluids. Starting fluids can explode and can cause a “run-away” vehicle condition.
WARNING
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot. They can cause fires and serious personal injury.
x Never park the vehicle where the hot exhaust system or catalytic converter could ignite flammable materials, such as brush, leaves, dry grass, spilled fuel, etc.
x Never apply additional undercoating or rust proofing on or near the exhaust manifold, exhaust pipes, catalytic converter, diesel particulate filter, or heat shields.

The air conditioner is most efficient when the windows and the power sunroof are closed. If the vehicle is stationary and the passenger compartment becomes very hot due to sunlight, briefly opening the windows and the power sunroof may speed up the cooling process.
Keep the air intake slots in front of the windshield free of ice, snow, and leaves so that the heating and ventilation systems can work properly.
Settings for optimum visibility
When you switch on the cooling system, both the temperature and humidity in the vehicle are reduced. This will help make passengers feel more comfortable and help keep the windows from fogging up.
For manual air conditioning
x Switch off the air recirculation ⇒  Air recirculation.
x Set the fan to the desired speed.
x Turn the temperature knob to the center position.
x Open and adjust all air vents in the instrument panel ⇒  Air vents.
x Turn the air distribution knob to the desired setting.
x Push the !

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 wind-shield-integrated antenna and never clean the antenna with corrosive or acidic cleaning agents or other chemicals.

x Never apply additional undercoating or rust proofing on or near the exhaust manifold, the exhaust pipes, the catalytic converter, the heat shields, or any other hot vehicle component.
