Special seat heating features
On the driver and the passenger side, the seat heating will resume at the setting that was set when
the ignition was switched off. However, this feature only works if the key is not taken out of the ignition
switch, or, for vehicles with Keyless Access, the driver door is not opened or the vehicle is not locked.
People suffering from a low level of perceived pain or a lowered awareness of pain as from
medication, paralysis, or chronic illness (e.g. diabetes) should NEVER use the seat heating feature ⇒
!
The use of seat heating by persons with these conditions could result in burns to the back, buttocks,
and legs that may take a long time to heal and may never heal completely. If you have any of these
conditions, you should take regular breaks and get out of the vehicle, particularly on long trips.
Consult your doctor for advice regarding your specific condition.
WARNING
Certain medical conditions, such as paralysis and diabetes, and certain medications can
increase the risk of serious burns when the seat heating feature is switched on.
x Vehicle occupants who have a low level of perceived pain or a lowered awareness of pain
can receive serious burns to the back, buttocks, and legs that take a long time to heal or may
never heal completely.
x Never use the seat heating feature if you or your passengers are at risk of being burned
because of a medical condition. Take regular breaks and get out of the vehicle, particularly
on long trips. Consult your doctor for advice regarding your specific condition.
x Never let exposed skin remain in contact with the seat upholstery when the seat heating is
being used.

WARNING
Parking improperly can cause serious personal injury.
x Never remove the key from the ignition switch while the vehicle is moving or rolling to a
stop. The steering wheel will lock and you will not be able to steer or control the vehicle.
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 Always apply the parking brake when parking your vehicle.
x Improper use of the parking brake can seriously injure you and your passengers.
x Never use the parking brake to slow down the vehicle when it is moving, except in an
emergency. The stopping distance is much longer because only the rear wheels are braked.
Always use the foot brake to stop the vehicle.
x Never activate the throttle manually from the engine compartment when the engine is
running and the automatic transmission is in gear. The vehicle will start to move as soon as
the engine speed increases even if the parking brake is on.
x Never leave children or anyone who cannot help themselves behind in the vehicle. They
could release the parking brake and move the gear selector lever or gear shift, which could
cause the vehicle to start moving. This can lead to a crash and serious personal injuries.
x Always take the key with you when you leave the vehicle. The engine can be started and
vehicle systems such as the power windows can be operated, leading to serious personal
injury.
x Never leave children, disabled persons, or anyone who cannot help themselves in the
vehicle. The doors can be locked with the remote control vehicle key, trapping passengers in
the vehicle in an emergency. For example, depending on the time of year, people trapped in
the vehicle can be exposed to very high or very low temperatures.
x Heat build-up in the passenger and luggage compartment of a parked vehicle can result in
temperatures in the vehicle that are much higher than the outside temperatures, particularly
in summer. Temperatures can quickly reach levels that can cause unconsciousness and
death, particularly to small children.

NOTICE
x Always be careful when you park in areas with parking barriers or high curbs. These vary in
height and could damage your bumper and related parts if the front of your vehicle hits a
barrier or curb that is too high while you are getting into or out of a parking spot. To help
prevent damage, stop before the tires of your vehicle touch a parking barrier or curb.
x Always be careful when you enter a driveway or drive up or down steep ramps or over
curbs or other obstacles. Parts of the vehicle close to the ground may be damaged (such as
bumper covers, spoilers, and parts of the engine, suspension, and exhaust systems).
Warning and indicator lights

The air recirculation mode helps prevent outside air from entering the vehicle interior
In very hot outside temperatures, temporarily switch to air recirculation in order to cool the vehicle
interior faster.
For safety reasons, air recirculation is switched off when the air distribution switch is turned to <\
⇒.
Switching air recirculation on and off - Manual AC
Switching on: Press the button 3 until the indicator light in the button comes on.
Switching off: Press the button 3 until the indicator light in the button goes out.
Switching air recirculation on and off - Heating and ventilation system
Switching on: Press the button  until the indicator light in the button comes on.
Switching off: Press the button until the indicator light in the button goes out.
WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents,
collisions and serious personal injury.
x Never use air recirculation mode over an extended period of time, since no fresh air will
enter the passenger compartment.
x 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.

NOTICE
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.

Winter diesel
At temperatures below 20 °F (-7 °C), wax separation in ULSD occurs. Wax may clog the fuel filter or
tank filter and keep the engine from running.
To help prevent the filter from being clogged with wax, the fuel filter in your vehicle is heated with
warm fuel when the engine is running (filter preheating system). Heating the fuel filter makes it
possible to use your vehicle with ULSD down to about -10 °F (-24 °C).
If you expect temperatures below +5 °F (-15 °C) ask your fuel dealer if their ULSD is sufficiently
winterized.
If non-winterized or insufficiently winterized diesel fuel has already thickened to the point that the
engine will not start, move the vehicle to a heated garage or workshop until it has warmed up.
Cold diesel engines normally produce louder noises during winter conditions than during warmer
periods. In addition, the exhaust gases may be light blue in color until the engine has warmed up. The
exhaust gas volume varies depending on the outside temperature.
Do not let your diesel engine idle unnecessarily after a cold start. Driving off slowly will shorten the
warm-up period.
WARNING
Starting fluids can explode and cause a run-away vehicle condition.
x Never use starting assist fluids.

NOTICE
x The vehicle's diesel engine was designed solely for use with ULSD fuel. For this reason,
never use gasoline, heating oil, or other fuels that have not been expressly approved for use
with the diesel engine. These fuels contain substances that will severely damage the fuel
system and the engine. Such damage will not be covered by any Volkswagen Limited Warranty.
x If you put any amount of the incorrect fuel in the fuel tank, do not start the engine under any
circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized
Volkswagen Service Facility for assistance.
x If diesel fuel should get on any rubber hose, it must be wiped off immediately. The same
applies if diesel fuel gets onto other parts of the vehicle, especially paint, tires, or a plastic
part. Wash the contaminated vehicle parts right away with soap and warm water to help
prevent leaks and serious damage.
x The vehicle is designed to run on diesel fuel containing methyl ester biodiesel in
concentrations of 5% or less. Never use methyl ester biodiesel in blend levels higher than 5%
(5%/ methyl ester blends are sometimes designated or labeled as B5). The properties of methyl
ester biodiesel blends in levels greater than 5% may cause serious damage to the fuel injection
system and to the engine. This could lead to expensive repairs that will not be covered by any
Volkswagen Limited Warranty.
x Damage to the engine and fuel system and performance problems caused by using fuels
that are different from those specified above or by using “starting assist fluids” are not the
responsibility of Volkswagen and are not covered under the Emission warranties or any other
Volkswagen Limited Warranty.

WARNING
High voltage systems in the engine compartment can cause electrical shocks or even
electrocution, severe burns, other serious injuries, and even death!
x Never short-circuit the electrical system. Be especially careful when using jumper cables.
The vehicle's battery could explode!
x To reduce the risk of electrical shock and personal injury while the engine is running or
being started:
– Never touch ignition cables. Never touch other components of the high voltage
electronic ignition system.
– Never touch the wiring of the HID – High Intensity Discharge (Xenon) headlights.
x Read and heed the important information and warnings on cleaning the engine
compartment , Cleaning the engine compartment

WARNING
Moving parts in the engine compartment can cause serious personal injury on contact.
x Never reach into the area around or touch the radiator fan. Contact with the blades can
cause serious personal injury. Always remember that the radiator fan is temperature-
controlled and can come on suddenly even when the engine has been switched off for a while
and the key has been removed from the ignition.
x If you have to perform a check or repair when the engine is running, there are more risks
from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the
high-voltage ignition system. Always use extreme care.
– Always make sure that jewelry, loose clothing and long hair do not get caught in
rotating engine parts. Before starting any work remove your jewelry, take off your necktie,
tie back and cover your hair, and do not wear clothing that can hang down and get caught
in moving engine parts.
– Always use extreme caution if the accelerator pedal has to be depressed to perform a
check. The vehicle will start to move even if the parking brake is on.
x Never leave any objects in the engine compartment, for example cleaning rags and tools.
Objects left behind can cause malfunctions, engine damage, and even fires.

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.
The following table explains what to do if the engine coolant warning light ¿ does not go out a few
seconds after the engine is started, or if it starts flashing while driving.
