 High beams switched on or headlight
flashers in use.

When the ignition is switched on, several warning and indicator lights come on briefly for a function
check. They go out after a few seconds.
WARNING
Failure to heed warning lights and instrument cluster text messages can cause the vehicle to
break down in traffic and result in a collision and serious personal injury.
x Never ignore warning lights or text WARNINGS.
x Always stop the vehicle as soon as it is safe to do so.
x Whenever stalled or stopped for repair, move the vehicle a safe distance off the road, stop
the engine, turn on the emergency flashers, and use other warning devices to warn approach-
ing traffic.
x Never park the vehicle in areas where the hot catalytic converter and exhaust system can
come into contact with dry grass, brush, spilled fuel, oil, or other material that can catch fire.
x 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
electrodes 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.

x Dirt: Caked-on dust, wax, any other buildup on the windshield (lotus effect), or car-wash detergent
residue can lower the rain sensor's sensitivity and cause it to react too slowly or not at all.
x Crack or chip in the windshield: If a stone hits and chips the windshield while the rain sensor is on,
this will trigger a wiper cycle. After that, the rain sensor will recognize the change and re-calibrate itself
to respond to the sensitive surface's reduced detection zone. Depending on the size of the chip, the
sensor's reaction pattern may or may not change.
WARNING
The rain sensor cannot always recognize rain and activate the wipers.
x Switch the wipers on manually when water on the windshield reduces visibility.
Clean the rain sensor's sensitive surface (arrow) regularly and check the wiper blades for wear or
damage.
To remove wax and coats of polish safely, we recommend using an alcohol-based windshield
cleaner.
Checking and refilling windshield washer fluid

WARNING
Wet brakes or brakes coated with ice or road salt react slower and need longer stopping
distances.
x Carefully apply the brakes to test them.
x 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 stopping distances and can cause
accidents and serious personal injuries.
x Never let the vehicle coast when the engine is switched off.
x 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
x Never “ride” the brakes by keeping your foot on the brake pedal 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.
x 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 openings in the wheel rims or from underneath the vehicle. If
necessary, the wheels can be taken off for a more thorough inspection.

Braking assistance systems

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
Brake failure and reduced brake performance can be caused by not having enough brake
fluid in the reservoir or by old or incorrect brake fluid.
x Check the brake system and brake fluid level regularly.
x Always change the brake fluid according to the service schedule in your
⇒ Booklet Warranty and Maintenance.
x Hard braking with old brake fluid may cause vapor lock. Vapor lock reduces braking
performance, increases stopping distances and can even cause total brake failure.
x Always make sure that only the correct brake fluid is used. Only use brake fluid that
expressly conforms to VW standard 501 14 or if it is not available, only use a high-quality
brake fluid that conforms to U.S. Standard FMVSS 116 DOT 4 requirements.
x Using another brake fluid, or one that is not of high quality, can impair the function of the
brake system and reduce its effectiveness. If the container does not say that the brake fluid
complies with VW Standard 501 14, or U.S. Standard FMVSS 116 DOT 4, do not use it.
x The brake fluid must be new.
WARNING
Brake fluid is poisonous.
x To reduce the risk of poisoning, never use food, beverage or other non-original containers
to store brake fluid. Someone might be misled by the original label on the container, or by the
shape of the container, and drink the brake fluid. This could occur even if you relabel the
container as “brake fluid.”
x Only store brake fluid in the closed, original container and keep it out of the reach of
children.
NOTICE
Brake fluid will damage vehicle paint, plastic parts and tires. Wipe any brake fluid off vehicle
paint and other vehicle parts immediately.
Brake fluid can pollute the environment. Brake fluid that has leaked out must be collected and
disposed of properly, following all applicable environmental regulations.

Lights
up Possible cause Proper response

steering system checked.
Otherwise, have the steering checked
immediately by an authorized Volkswagen
dealer or an authorized Volkswagen Service
Facility.

WARNING
Poor visibility increases the risk of collisions and other accidents that cause serious
personal injuries.
x Always make sure all windows are clear of ice, snow and condensation for good visibility
to the front, sides, and rear.
x 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.
x Always make sure you know how to properly use the heating and ventilation systems as
well as the rear window defroster that you will need for good visibility.
x Never use air recirculation for long periods of time. When the air conditioner is off and
recirculation mode is on, condensation can quickly form on the windows and greatly reduce
visibility.
x 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 injury.
x Never switch off the fan for a long period of time and never use air recirculation a long
period of time because no fresh air will enter the passenger compartment.
NOTICE
x 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 authorized Volkswagen Service Facility.
x Air conditioner repair requires specialized knowledge and special tools. Volkswagen
recommends that you see an authorized Volkswagen dealer or an authorized Volkswagen
Service Facility.
x Do not smoke when air recirculation is switched on. Smoke drawn into the ventilation
system can leave residue on the evaporator and on the dust and pollen active carbon filter,
resulting in permanent odors whenever the air conditioner is switched on.
If the air conditioner is switched off, the fresh outside air will not be dehumidified. To help keep
the windows from fogging over, Volkswagen recommends leaving the air conditioner (compressor)
switched on. Press the AC button. The indicator light in the button must come on.
When it is very hot and humid outside, water condensation can drip from the air conditioner
evaporator and form a puddle under the vehicle. This is normal and does not indicate a leak.
Keep the air intake slots in front of the windshield free of ice, snow and leaves in order to
maintain proper functioning of the heating and ventilation systems.
Maximum heating output and defrosting performance are not possible until the engine has
reached operating temperature.

Emergency starting and starting the engine with a very weak vehicle battery or after the vehicle
battery has been replaced may change or delete settings (including time, date, personal convenience
settings and programming). Check the settings and correct as necessary once the vehicle battery has
built up a sufficient charge.
