WARNING
Driving on today's roads demands the full attention of the driv-
er at all times. Driver distraction causes accidents, collisions
and serious personal injury!
Never access menus when the vehicle is moving.
Emergency starting and starting the engine with a very weak ve-
hicle battery or after the vehicle battery has been replaced may
change or delete system settings (including time, date, personal con-
venience settings, and programming). Check the settings and correct
as necessary once the vehicle battery has built up a sufficient charge.

resistance or there is something in the way, the power sunroof opens
again immediately.
Check why the power sunroof did not close.
Try to close the power sunroof again by pulling the h switch brief-
ly.
If the power sunroof still cannot close, the power sunroof will stop
where the resistance is located. The power sunroof will close the next
time without pinch protection.
Closing the power sunroof without pinch protection
Within 5 seconds after the pinch protection was triggered, pull the
switch ⇒ fig. 40 until the power sunroof closes completely.
The power sunroof will now close without pinch protection!
If the power sunroof still will not close, please see an authorized
Volkswagen dealer or an authorized Volkswagen Service Facility.
WARNING
Careless or unsupervised use of the sunroof can cause serious
injuries.
Always make sure that no one is in the way of the power sun-
roof when it is closing.
Always take all vehicle keys with you when leaving the vehi-
cle.
Never leave children or persons requiring assistance unat-
tended in the vehicle, especially if they have access to the ve-
hicle key. Unsupervised use of the remote control vehicle key
can lock the vehicle, start the engine, switch on the ignition and
operate the sunroof.
The sunroof can still be opened or closed for a short period
after the ignition has been switched off, as long as the driver or
passenger door is not opened.

WARNING
Failure to heed warning lights and instrument cluster text mes-
sages can cause the vehicle to break down in traffic and result
in a collision and serious personal injury.
Never ignore warning lights or text WARNINGS.
Always stop the vehicle as soon as it is safe to do so.
Whenever stalled or stopped for repair, move the vehicle a
safe distance off the road, stop the engine, turn on the emer-
gency flashers, and use other warning devices to warn ap-
proaching traffic.
Never park the vehicle in areas where the hot catalytic con-
verter and exhaust system can come into contact with dry
grass, brush, spilled fuel, oil, or other material that can catch
fire.
A broken down vehicle presents a high accident risk for itself
and others. Switch on emergency flashers and set up a warning
triangle to warn oncoming traffic.
NOTICE
Failure to heed warning lights or text WARNINGS can result in
vehicle damage.
High Intensity Discharge (HID) headlights provide bright, uniform
lighting to help you see and be seen. The light comes from an electric
arc between two electrodes in the gas-filled bulb. Over time, the elec-
trodes can wear down and the gap between them will get wider. The
HID lamp’s control unit then increases the voltage to keep the arc’s
brightness constant. However, the commonly called “Xenon” bulbs
will also ultimately burn out. Before they burn out, HID lamps can
flicker. A message will then appear in the MFI. This is your reminder
to see an authorized Volkswagen dealer or an authorized
Volkswagen Service facility to check the headlights.

To remove wax and coats of polish safely, we recommend using
an alcohol-based windshield cleaner.

WARNING
Wet brakes or brakes coated with ice or road salt react slower
and need longer stopping distances.
Carefully apply the brakes to test them.
Always dry brakes and clean off ice and salt coatings with a
few cautious brake applications when visibility, weather, road
and traffic conditions permit.
WARNING
Driving when the brake booster is not working increases stop-
ping distances and can cause accidents and serious personal
injuries.
Never let the vehicle coast when the engine is switched off.
If the brake booster is not working (such as when the vehicle
is being towed), a lot more pedal force is needed to slow down
and stop.
NOTICE
Never “ride” the brakes by keeping your foot on the brake pe-
dal when you do not want to brake. Constant pressure on the
brake pedal can make the brakes overheat. Riding the brakes
will substantially reduce braking performance, increase stopping
distance, and can cause complete brake system failure.
Before driving downhill, especially on hills that are long or
steep, always reduce speed and shift into lower gear (manual or
automatic transmission). This will let the vehicle use engine
braking and reduce the load on the brakes. Otherwise, the brake
system could overheat and possibly fail. Only use the brakes
when you need them to slow the vehicle down more or to stop.
When the front brakes are serviced, you should have the rear
brake pads inspected at the same time. The wear of all brake pads
should be visually checked regularly. The best way to check for brake
pad wear is to have your authorized Volkswagen dealer or authorized
Volkswagen Service Facility visually inspect the pads through the

Check the information on the container for the brake fluid you want to
use to make sure it meets the requirements for your vehicle.
Brake fluid that complies with VW Standard 501 14 can be pur-
chased from your authorized Volkswagen dealer or authorized
Volkswagen Service Facility.
If this special brake fluid is not available you may – under these cir-
cumstances – use another high quality brake fluid that complies with
U.S. Federal Motor Vehicle Safety Standard (FMVSS) 116 DOT 4 ⇒ 
.
Please note, however, that not all brake fluids that comply with U.S.
Federal Motor Vehicle Safety Standard FMVSS 116 DOT 4 have the
same chemical composition. Some of these brake fluids can contain
chemicals that could, over time, degrade or damage internal parts of
the vehicle’s brake system.
Volkswagen therefore recommends that you use brake fluid that ex-
pressly complies with VW Standard 501 14 for optimum brake sys-
tem performance over the long term.
Brake fluid level
The fluid level in the transparent brake fluid reservoir must always be
between the MIN and MAX marking ⇒ .
On some vehicles, engine components block the view of the brake
fluid reservoir and make it impossible to see the brake fluid level. If
you cannot clearly see the brake fluid level in the brake fluid reservoir,
please see an authorized Volkswagen dealer or authorized
Volkswagen Service Facility.
The brake fluid level drops slightly when the vehicle is being used as
the brake pads wear and the brakes are automatically adjusted.
Changing brake fluid
Brake fluid must be changed according to the service schedule in
your ⇒ Booklet Warranty and Maintenance. Have the brake fluid
checked by an authorized Volkswagen dealer or an authorized
Volkswagen Service Facility. Refill only with new brake fluid that
meets the standards listed above.

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-

Air conditioner does not work
The air conditioner may not switch on for one of the following rea-
sons:
The engine is not running.
The fan is switched off.
The air conditioner fuse has blown.
The outside air temperature is colder than about +38 °F (+3 °C).
The air conditioner compressor has been temporarily switched off
due to excessive engine coolant temperature.
There is another malfunction in the vehicle. Have the air condition-
er checked by an authorized Volkswagen dealer or authorized
Volkswagen Service Facility.
Special considerations
When it is very hot and humid outside, water condensation can drip
from the air conditioner evaporator and form a puddle under the vehi-
cle. This is normal and does not indicate a leak.
The climate control system adjusts the passenger compartment
temperature as fast as possible considering the outside temperature.
Due to residual moisture in the air conditioner, the windshield
may fog up after the engine is started. Switch on the windshield de-
froster to help evaporate the condensation as quickly as possible.
The air coming out of the vents flows through the passenger
compartment and through the vents under the rear window. Do not
cover these slots with clothing or other things.

WARNING
Starting fluids can explode and cause a run-away vehicle condi-
tion.
Never use starting assist fluids.
NOTICE
Never use fuel with an octane rating lower than 87 AKI /
91 RON. Using lower octane fuel may cause expensive engine
damage.
Never use leaded gasoline! Leaded gasoline will severely
damage your vehicle's catalytic converter.
Methanol-blended fuels that do not meet the criteria listed
above may cause corrosion and may damage plastic and rubber
parts in the fuel system.
Never use fuels that contain lead or other metals (check listing
on the fuel pump). Even lead replacement gasoline (LRP fuels)
contain metallic additives in high concentrations. They can
damage the engine.
Do not use fuels that fail to meet the criteria above, or with
contents that cannot be identified.
If you cannot tell whether a particular fuel blend meets the cri-
teria above, ask your service station or its fuel supplier. If you
notice a loss of fuel economy or drivability and performance
problems using one of these fuel blends, we recommend that
you switch to unblended fuel.
Using fuels that are different from those specified above can
damage your vehicle's engine and fuel system and cause per-
formance problems.
Damage to the engine and fuel system and performance prob-
lems caused by using fuels that are different from those speci-
fied above or by using “starting assist fluids” are not the re-
sponsibility of Volkswagen and are not covered under the Emis-
sion warranties or any other Volkswagen Limited Warranty.
Even a single tank full of leaded fuel can do major damage to the
catalytic converter and degrade its effectiveness in reducing polluting
emissions.
