WARNING
Even if empty, portable fuel containers can leak and cause a fire and serious personal
injuries, especially in a crash.
x For your safety, we strongly recommend that you do not travel with a portable fuel
container in your vehicle.
x If, under exceptional circumstances, you must transport a portable fuel container, please
observe the following:
– Never fill a portable fuel container while it is anywhere in or on the vehicle (for
example, in the luggage compartment or on top of the luggage compartment lid). Static
electricity can build up while filling and can ignite fuel vapors, causing a fire.
– Always place a portable fuel container on the ground before filling. Never spill fuel
inside the vehicle or luggage compartment. Fuel vapors are highly flammable.
– Always keep the filler nozzle completely inside the portable container before and
during filling.
– If filling a portable container made of metal, the filler nozzle must always be in contact
with the container. This will help prevent static electricity from discharging and causing a
fire.
– Always observe local and state or provincial laws about the use, storage, and
transportation of portable fuel containers.
– Make certain that the portable fuel container meets industry standards, such as ANSI /
ASTM F852-86.
NOTICE
x Remove fuel spills from the vehicle immediately to help prevent damage to the paint, tires,
and wheel housings.
x Refueling with gasoline when your vehicle has a diesel engine or refueling with diesel fuel
when your vehicle has a gasoline engine can cause very serious and expensive engine and
fuel system damage that is not covered by any Volkswagen Limited Warranty.
x If you put any amount of 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. These fuels contain substances that can severely
damage the fuel system and the engine if the engine is started.
x Vehicles with diesel engines must never be refueled or driven with gasoline, kerosene,
heating oil, or other non-specified fuels that have not been expressly approved for use with the
diesel engine. Other kinds of fuel can cause serious damage to the fuel system and the engine
that is not covered by any Volkswagen Limited Warranty.
Fuels can pollute the environment. Spilled fuel must be collected and disposed of properly,
following all applicable environmental regulations.
There is no emergency release for the fuel filler flap. Contact an authorized Volkswagen dealer or
an authorized Volkswagen Service Facility for assistance.

WARNING
Driving with a fuel tank that is almost empty can lead to stalling in traffic, a collision, and
serious personal injuries.
x When the fuel tank is almost empty, fuel supply to the engine can be interrupted,
especially when driving over bumps, across slopes, and up and down hills.
x Steering and braking assistance as well as ESC and related systems will not work if the
engine “sputters” or stalls due to lack of fuel.
x Always refuel when the tank is 1/4 full to reduce the risk of running out of fuel and stalling
in traffic.
NOTICE
x Failure to heed warning lights or text WARNINGS can result in vehicle damage.
x Never drive until the fuel tank is completely empty. The irregular fuel supply can cause the
engine to misfire. This allows unburned fuel to get into the exhaust system and damage the
catalytic converter or the diesel particulate filter.
The small arrow next to the gas pump symbol in the fuel gauge shows the side of the vehicle with
the fuel filler flap.

slightly with light pressure to open the misfueling guard. If the misfueling guard cannot be opened this
way, see the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility and
have the fuel system checked.
WARNING
Spilled fuel can cause fires, explosions, burns, and other severe injuries.
x Do not refuel from devices other than correct, undamaged standard diesel fuel pump
nozzles.
x Always stop refueling once the pump nozzle switches off so that the tank does not
overflow.
NOTICE
x It is your responsibility to put the right fuel in your vehicle and any damage that results is
not covered under the Emissions warranties or any other 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 Never force a fuel nozzle in the misfueling guard. If you have problems inserting a fuel
nozzle, first check to make sure you are using the correct diesel fuel. If you are, go to a pump
with the standard diesel nozzle. Forcing a fuel nozzle in the misfueling guard can damage it so
that it can no longer help prevent misfueling.

Fuel capacities

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.

Preparations for working in the engine compartment

WARNING
The engine compartment of any motor vehicle is a potentially dangerous area and can cause
serious personal injury.
x Always use extreme caution when doing any work in the engine compartment. Always
follow commonly accepted safety practices and use common sense. Never risk personal
injury.
x Never perform any work in the engine compartment unless you know exactly how to carry
out the job and have the correct technical information and the correct tools.
x If you are uncertain about what to do, have the work performed by an authorized
Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified
workshop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID – High Intensity Discharge (Xenon)
headlights and H7 bulbs replaced by a qualified technician. Serious personal injury may
result from improperly performed work.
x Never open or close the engine hood if steam or coolant is escaping. Hot steam or coolant
can cause serious burns. Always wait until you no longer see or hear steam or coolant
escaping from the engine.
x Always let the engine cool down completely before carefully opening the hood.
x Hot parts of the engine and the exhaust system will burn skin on contact.
x When the engine has cooled down and you are ready to open the hood:
– Firmly apply the parking brake and shift the transmission into Park (P) (automatic) or
Neutral (manual only).
– Take the vehicle key out of the ignition.
– On vehicles with Keyless Access, make sure that the remote control vehicle key is out
of range of the vehicle and that the vehicle cannot be started by depressing the starter
button.
– Always keep children and others away from the engine compartment and never leave
them unsupervised.
x The engine coolant system is under pressure when the engine is hot. Never unscrew the
coolant expansion tank cap when the engine is hot. Hot coolant can spray out and cause
severe burns and other serious injuries.
– Turn the cap slowly and very carefully in a counterclockwise direction while applying
light downward pressure on the top of the cap.
– Always protect your face, hands, and arms from hot escaping coolant or steam by
covering the cap with a large, thick rag.
x Never spill fluids on the engine or exhaust system when refilling. Spilling fluids onto hot
parts of the engine or exhaust system can cause a fire.
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.

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.
WARNING
Operating fluids and some materials in the engine compartment can catch fire easily, causing
burns and other serious personal injuries!
x Do not smoke.
x Never work next to open flames or sparks.
x Never pour or spill operating fluids or other flammable liquids on the engine. These fluids
can ignite on hot engine parts and cause injuries.
x If work on the fuel system or the electrical system is necessary:
– Always disconnect the 12 Volt vehicle battery. Make sure the vehicle is unlocked when
you disconnect the battery, or the alarm will go off. Never touch the electrical wiring of the
ignition system.
– Never work near heaters, water heaters, or other open flames.
x Always have a functional, approved fire extinguisher nearby.
NOTICE
When changing or topping off fluids, make sure that you pour the fluids into the correct
reservoirs. Adding the wrong type of operating fluids will cause serious malfunctions and
engine damage.
Fluid leaks and spills are harmful to the environment. Regularly check the ground underneath
your vehicle for this reason. If you find spots of oil or other fluids, have your vehicle checked by your
authorized Volkswagen dealer or authorized Volkswagen Service Facility. Dispose of leaked operating
fluids properly.
