with indicator lights.
General information

Fig. 31 The CSC roof folds down into the luggage compartment when you open the roof (put the roof down).

WARNING
Accidents and severe injuries can result if the CSC roof is opened or closed when someone
is in the way.
x Never open or close the CSC roof unless the vehicle is parked at a safe distance from
traffic.
x Do not open or close the CSC roof unless you have made sure that nobody is in the way
of the luggage compartment lid, the roof system, or other moving parts.
x Check to make sure that the closed CSC roof is securely latched.
x If CSC roof operation is interrupted, please note the following:
– The CSC roof may not stop moving immediately. Gravity may cause the CSC roof to
keep moving.
– Gradually (may take up to 8 minutes), the CSC roof will automatically lower itself into a
balanced position.
– The CSC roof is, however not latched in this position. Stop!
WARNING
If interruption of opening or closing process causes the roof to come to rest in its forward
position, the roof will not be latched.
x If you are unable to get the CSC roof to close “normally,” latch the roof using the
emergency closing procedure
x Watch for a message in the instrument cluster display indicating whether the roof has
been properly closed.
NOTICE
Frequent opening and closing of the CSC roof drains the vehicle battery. To help prevent the
battery from running down, you should keep the engine running if you need to open and close
the roof frequently.
NOTICE
If the CSC roof is open, rain could enter the vehicle and wet the interior, causing vehicle
damage.
x Always close the CSC roof and lock the doors and the luggage compartment before leaving
the vehicle.
NOTICE
The height of the vehicle changes when the CSC roof is moving. When there is not enough
room above the vehicle, for example in a garage, the CSC roof could hit something and be
damaged.
x Always make sure that there is enough room above the vehicle when opening or closing the
CSC roof.
If you park vehicle with the roof down, the passenger compartment can be damaged by rain or
snow, and it is also open to unauthorized persons. Volkswagen recommends closing the CSC roof

WARNING
The Automatic Rollover Support System can cause serious injuries if persons or objects are
in the way when it deploys.
x Never use accessory seat covers or protective covers that block the rollover protection
deployment area.
x Every rear seat passenger must be properly seated on a seat of his or her own and must
stay in a proper seating position at all times.
x Always keep the area around the supports free of anything that could interfere with their
deployment or fly about and injure occupants when the supports deploy.
x Never take the covers off the Automatic Rollover Support System.
x Never attach a child seat, child restraints, straps, or anything else to the rollover
protection supports.
WARNING
If there is a system malfunction, the Automatic Rollover Support System may cause serious
injuries by not deploying properly, by not deploying at all, or by deploying unexpectedly.
x If a malfunction exists in the system, have it checked immediately by an authorized
Volkswagen dealer or an authorized Volkswagen Service Facility. A malfunction exists in the
system if the indicator light:
– does not come on when the ignition is turned on;
– does not go out about 5 seconds after you start the engine;
– goes out after switching on the ignition and then comes back on again;
– comes on or flickers when you are driving.
NOTICE
If deployed, the Automatic Rollover Support System can damage the CSC roof when opening
or closing the top.
x Do not open or close the CSC roof if the Automatic Rollover Support System has deployed.

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
approaching 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.

Possible reasons for changes in the way the rain sensor works
The rain sensor may misread what is happening in the detection zone of its sensitive rain-sensor
surface ⇒ fig. 91 (arrow) and not work for a number of reasons; which include:
x Worn out wiper blades: Worn out wiper blades may leave a film of water or wiping streaks; this can
cause the wipers to run longer, to wipe more often, or to wipe continuously at high speed.
x Insects: Insects hitting the sensor may trigger the wipers.
x Salt streaks: Salt streaks on the windshield from winter driving can cause wiping more often or
continuously on glass that is almost dry.
x Dirt: Caked-on dust, wax, any other build-up 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 recalibrate 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

Fig. 92 In the engine compartment: Cap of the windshield washer fluid reservoir.

x Check if there is still enough windshield washer fluid in the reservoir.
x Refill with an appropriate windshield washer fluid that is recommended by Volkswagen ⇒ .
Follow the directions on the container.
x In cold weather, always use a special windshield washer antifreeze solution that will help keep the
water from freezing ⇒ .
Recommended cleaners
x For the warmer months, Windscreen Clear SummerG 052 184 A1 or equivalent. Mixing ratio
1:100 (1 part concentrate to 100 parts water) in the windshield washer reservoir.
x All-season Windscreen ClearG 052 164 A2 or equivalent. Mixing ratio in winter to 0 °F (-18 °C)
about 1:2 (1 part concentrate to 2 parts water), otherwise, mixing ratio 1:4 in the windshield washer
reservoir.
Filling capacity
The windshield washer fluid reservoir holds 3.1–4.2 quarts (about 3–4 liters); in vehicles with a
headlight cleaning system 3.1–6.3 quarts (about 3–6 liters).
WARNING
Never mix antifreeze or similar additives into the windshield washer reservoir. This could
produce an oily film on the windshield, which would considerably reduce visibility.
x Use clear water with a cleaning solution recommended by Volkswagen.
x If necessary, blend with a suitable windshield washer fluid antifreeze agent.
NOTICE
x Never mix cleaning solutions recommended by Volkswagen with other cleaning agents. If
you do, this could cause sediments or other by-products that can clog the windshield wiper
nozzles.
x When refilling, do not confuse one type of operating liquid with another! Otherwise serious
malfunctions and engine damage can occur!

Emergency shift program
If all selector lever position indicators in the instrument cluster display are highlighted against a bright
background, there is a system malfunction. The automatic transmission and the DSG automatic
transmission will then operate in the emergency shift program. The emergency shift program lets you
drive the vehicle, but at a reduced speed and without being able to use all of the forward gears.
In some cases, vehicles with a DSG® Direct Shift Gearbox automatic transmission may not be able to
shift into reverse. It is then impossible to drive the vehicle backwards.
In any event, have the automatic transmission checked by an authorized Volkswagen dealer or
authorized Volkswagen Service Facility.
Overheating of Direct Shift Gearbox (DSG®) automatic transmission
The DSG® automatic transmission may overheat, for example, due to frequent starts, extended
“creeping,” or stop-and-go traffic. Overheating is indicated by the warning light Á and, if applicable, by
a text message in the instrument cluster. An additional warning chime may sound. Stop and let the
transmission cool down ⇒ .
The vehicle does not move forward or in reverse even though a drive position is selected
with the selector lever
If the vehicle does not move in the desired direction, the system may not have engaged the drive
position correctly. Press the brake pedal and select the drive position again.
If the vehicle still does not move in the desired direction, there is a system malfunction. See your
authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance to have the
system checked.
NOTICE
x As soon as you get any of these warnings about transmission overheating, you must either
park the vehicle in a safe place or drive faster than 12 mph (20 km/h).
x If the text message and acoustic warning repeat themselves every 10 seconds or so, you
must park the vehicle in a safe place as soon as you can safely do so and stop the engine. Let
the transmission cool down.
x To help prevent damage to the transmission, do not drive the vehicle again until the
acoustic warning has stopped. As long as the engine is overheated, avoid stop and start
driving and avoid low speeds (“walking pace”).

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.
