outside temperature. It may be helpful to ventilate the vehicle before
driving and then to drive a short distance with the windows open. Af-
ter that, switch on the air conditioner with the windows closed. Keep
the windows closed when driving at high speeds. Open windows in-
crease fuel consumption.
Switch off seat heating once it has served its purpose.
Switch off the rear window defroster as soon as the windows are
free of fog and ice.
Additional factors that increase fuel consumption (examples):
Malfunctioning engine control.
Driving in the mountains.
Towing a trailer.
NOTICE
Never let the vehicle coast or roll down a hill in Neutral (N), es-
pecially when the engine is not running. The transmission will
not be lubricated and will be damaged.

Heating and air conditioning

WARNING
Poor visibility increases the risk of collisions and other acci-
dents that cause serious personal injuries.
Always make sure all windows are clear of ice, snow and
condensation for good visibility to the front, sides, and rear.
Maximum heating output and defrosting performance are not
possible until the engine has reached operating temperature.
Wait until you have good visibility before driving off.
Always make sure you know how to properly use the climate
control system as well as the rear window defroster that you
will need for good visibility.
Never use air recirculation for long periods of time. When the
air conditioner is off and recirculation mode is on, condensa-
tion can quickly form on the windows and greatly reduce visi-
bility.
Always switch off recirculation mode when it is not needed.
WARNING
Stale air causes driver fatigue and reduces driver alertness,
which can cause accidents, collisions and serious personal in-
jury.
Never switch off the fan for a long period of time and never
use air recirculation for a long period of time because no fresh
air will enter the passenger compartment.
NOTICE
If you think the air conditioner is not working properly or may
be damaged, switch it off to help prevent more damage. Have the
air conditioner checked by an authorized Volkswagen dealer or
an authorized Volkswagen Service Facility.
Air conditioner repair requires specialized knowledge and
special tools. Volkswagen recommends that you see an author-
ized Volkswagen dealer or an authorized Volkswagen Service
Facility.
Do not smoke when air recirculation is switched on. Smoke
drawn into the ventilation system can leave residue on the evap-

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.
Don't drive until you have clear visibility through all windows.
Remove ice, snow and condensation from all inside and out-
side window surfaces.
NOTICE
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 wind-
shield wiper nozzles.
Never use warm or hot water to remove snow and ice from
windows and mirrors. This could cause the glass to crack!
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.
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.
