– Place the cap in the housing on the hinge of the open flap
⇒ Fig. 151.
Closing the fuel tank cap
– Screw on the tank cap clockwise until it you hear it click into po-
sition.
– Close the tank flap. Make sure you hear it click into place.
If the automatic filler nozzle is operated correctly, it will switch itself off as
soon as the fuel tank is “full”. Do not try to put in more fuel after the nozzle
cuts out, as this will fill the expansion chamber in the fuel tank.
The correct fuel grade for your vehicle is given on a sticker on the inside of
the fuel tank flap. Further notes on fuel can be found at ⇒ page 246.
The capacity of the fuel tank is listed in the vehicle technical specifications
⇒ page 323.
WARNING
Fuel is highly flammable and can cause serious burns and other injuries.
● Do not smoke when filling the fuel tank or a canister. Naked flames
are forbidden in the vicinity due to the risk of explosion.
● Observe legislation governing the use, storage and carrying of a
spare fuel canister in the vehicle.
WARNING (Continued)
● For safety reasons we do not recommend carrying a spare fuel canis-
ter in the vehicle. In an accident the canister could be damaged and could
leak.
● If, in exceptional circumstances, you have to carry a spare fuel canis-
ter, please observe the following points:
–Never fill fuel into the spare fuel canister if it is inside or on top of
the vehicle. An electrostatic charge could build up during filling, caus-
ing the fuel vapour to ignite. Danger of explosion. Always place the
canister on the ground to fill it.
– Insert the filling nozzle as far as possible into the spare fuel canis-
ter.
– If the spare fuel canister is made of metal, the filling nozzle must
be in contact with the canister during filling. This helps prevent an
electrostatic charge building up.
– Never spill fuel in the vehicle or in the luggage compartment. Fuel
vapour is explosive. Risk of fatal accident!
CAUTION
● If any fuel is spilt onto the vehicle, it should be removed immediately. It
could otherwise damage the paintwork.
● Never run the tank completely dry. An irregular fuel supply could cause
misfiring. As a result, unburnt fuel could enter the exhaust system and dam-
age the catalytic converter.
● When filling the fuel tank after having run it completely dry on a vehicle
with a diesel engine , the ignition must be switched on for at least 30 sec-
onds before starting the engine. When you then start the engine it may take
longer than normal (up to one minute) for the engine to start firing. This is
because air needs to be bled from the fuel system while starting. 

For the sake of the environment
Do not overfill the fuel tank – it may cause the fuel to overflow if it becomes
warm.
Note
Diesel vehicles are fitted with a protective device that prevents the insertion
of the wrong fuel hose 1)
. It is only possible to refuel with Diesel nozzles.
● If the pump nozzle is worn, damaged, or if it is very small, it is possible
that it will not be able to open the protective device. Before trying to insert
the pump nozzle by turning it, try a different pump or request specialist
help.
● If you fill the tank from a reserve fuel canister, the protective device will
not open. One way to resolve this is to pour the fuel in very slowly. 
Refuelling natural gas

protection against overheating may disconnect this automatically.
● Remove the plug from the gas filler mouth ⇒ Fig. 152 1
.
● Connect the pump filling nozzle to the gas filler mouth.
● The fuel tank will be full when the pump compressor automatically cuts
the supply.
● If you wish to finish refuelling in advance, press the button on the pump
to stop the flow.
Closing the fuel tank cap
● Check that the gas filler mouth retainer 2
is not trapped with the filler
nozzle. If necessary, place it in the filler mouth again.
● Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it click into place. 

WARNING (Continued)
● Protect face, hands and arms by covering the cap with a large, thick
rag to protect against escaping coolant and steam.
● If it is necessary to work in the engine compartment while the engine
is running, the rotating components (for example, poly-V belt, alternator,
radiator fan) and the high voltage ignition system are an additional haz-
ard.
● Observe the following additional warnings if work on the fuel system
or the electrical system is necessary:
–Always disconnect the battery from the on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguisher immediately available.
CAUTION
When changing or topping up service fluids, make absolutely certain that
you fill the fluids into the correct reservoirs. Using the wrong fluids could
cause serious malfunctions and engine damage!
For the sake of the environment
Inspect the ground underneath your vehicle regularly so that any leaks are
detected at an early stage. If you find spots of oil or other fluids, have your
vehicle inspected at the workshop.
Note
On right-hand drive vehicles* some of the containers/reservoirs mentioned
below are located on the other side of the engine compartment. Opening the bonnet

hicle is moving, stop the vehicle immediately and close the bonnet. Fail-
ure to do so could result in an accident.
 Engine oil
General notes
The engine comes with a special, multi-grade oil that can be used all year
round.
Because the use of high-quality oil is essential for the correct operation of
the engine and its long useful life, when topping up or changing oil, use on-
ly those oils that comply with VW standards.
The specifications (VW standards) set out in the following page should ap-
pear on the container of the service oil; when the container displays the
specific standards for petrol and diesel engines together, it means that the
oil can be used for both types of engines.
We recommend that the oil change, indicated in the Maintenance Pro-
gramme, be performed by a Technical Service or a specialised workshop.
The correct oil specifications for your engine are listed in the ⇒ page 254,
Oil properties.
Service intervals
Service intervals can be flexible (LongLife service) or fixed (dependent on
time/distance travelled).
If the PR code that appears on the back of the “Maintenance Programme”
booklet is PR QI6, this means that your vehicle has the LongLife service pro-
grammed. If it lists the codes QI1, QI2, QI3, QI4 or QI7, the interval service
is dependent on time/distance travelled.
Flexible service intervals (LongLife service intervals*)
Special oils and processes have been developed which, depending on the
characteristics and individual driving profiles, enable the extension of the
oil change service (LongLife service intervals). 

WARNING
● Brake fluid should be stored in the closed original container in a safe
place out of reach of children. Risk of poisoning!
● If the brake fluid is left in the system for too long and the brakes are
subjected to heavy use, vapour bubbles may form in the brake system.
This would seriously affect the efficiency of the brakes and the safety of
the vehicle. This may cause an accident.
CAUTION
Brake fluid should not come into contact with the vehicle paintwork, as it is
abrasive. 
Battery General information
The battery is located in the engine compartment and is almost mainte-
nance-free. It is checked as part of the Inspection Service. Nevertheless,
check the terminals are clean and have the correct tightening torque, espe-
cially in summer and winter.
Disconnecting the battery
The battery should only be disconnected in exceptional cases. When the
battery is disconnected, some of the vehicle's functions are “lost” ( ⇒ table

The windscreen wiper blades are supplied as standard with a layer of graph-
ite. This layer is responsible for ensuring that the wipe is silent. If the graph-
ite layer is damaged, the noise of the water as it is wiped across the wind-
screen will be louder.
Check the condition of the wiper blades regularly. If the wipers scrape
across the glass they should be changed if they are damaged, or cleaned if
they are dirty ⇒ 
.
Damaged wiper blades should be replaced immediately. Wiper blades are
available from specialised workshops.
Raising/lowering windscreen wiper arms
For windscreen wipers, please note: the wiper should be in service position
