Introduction
Fuel gauge
Lit upPossible cause/remedy ⇒
Fuel tank almost empty. Reserve volume, red marking ⇒ Fig. 20, is
consumed ⇒ Fuel tank capacity.
Fill the tank as soon as possible ⇒ Fuel types and refuelling.
Water in fuel in vehicles with a diesel engine.
Reduce the vehicle speed immediately and drive to the nearest qualified
workshop at a medium engine speed and avoiding high engine loading.
OR: if the warning lamp lights up immediately after filling the tank, switch off
the engine and seek expert assistance.
When the indicator lamp lights up, the auxiliary heater and the fuel-powered supplementary
heater switch off automatically ⇒ Auxiliary heater and ventilation.

Coolant temperature display
Fig. 21 In the instrument cluster: coolant temperature display (illustration).
Driving when the fuel level is too low can lead to the vehicle coming to a standstill in
traffic, potentially causing accidents and serious injuries.
•When the fuel level is too low, the fuel supply to the engine could be irregular,
especially when driving up or down hills and inclines.
•The steering, all driver assist systems and brake support systems will not function if
the engine sputters or stops completely due to a lack of fuel or irregular fuel supply.
•Always fill the tank when it is still 1/4 full. This reduces the risk of running out of fuel
and breaking down.
WARNING
Do not run the tank empty. Irregular filling periods can cause backfiring and allow unburnt
fuel to enter the exhaust system. The catalytic converter or diesel particulate filter could be
damaged as a result!
NOTICE

Safety instructions for handling fuel
Fuels can pollute the environment. Any spilt service fluids must be cleaned up and disposed
of properly.
The tank flap cannot be opened manually. Seek expert assistance.
Fuel types and refuelling
Introduction
This chapter contains information on the followingsubjects:
⇒ Petrol
⇒ Diesel
⇒ Refuelling
⇒ Misfuelling prevention device
The tank flap is located at the rear right-hand side of the vehicle ⇒ Side view.
Different engines require different fuels. The factory-fitted sticker on the inside of the tank flap
indicates the required fuel type for your vehicle.
Information on indicator and warning lamps can be found in the troubleshooting section at the end
of the chapter ⇒ Troubleshooting.
Petrol
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Vehicles with a petrol engine must be run on unleaded petrol. Fuels with a maximum ethanol
content of 10% (E10) can be used for refuelling ⇒.
The petrol grades differ with respect to the octane number. The vehicle may be filled with petrol that
has a higher octane number than the engine requires. However, this does not provide any
advantage in terms of fuel consumption or engine output.
The fuel quality affects the running properties, performance and service life of the engine. You
should therefore use fuel that already contains suitable service additives if possible ⇒.
Information on the fuel standards can be found in the chapter on fuel standards ⇒ Fuel standards.
Incorrect handling of fuel can cause explosions, fire, serious burns and other injuries.
•Switch off the auxiliary heater⇒ Auxiliary heater and ventilation, the engine, the
ignition, your mobile phone and other wireless equipment while refuelling.
•Do not get into the vehicle to avoid electrostatic discharge.
•Make sure that the tank cap is closed properly and no fuel can escape.
•Comply with any relevant safety information and legislation concerning the handling of
fuels.
WARNING
Fuel may run out of the fuel canister. This could cause fire and injuries.
•Do not carry fuel canisters in the vehicle.
CAUTION
Incorrect refuelling can lead to damage to the vehicle.
•Only use fuels that have been approved for the vehicle.
•Do not use fuels containing metals and only use approved additives.
•Spilt fuel should be removed from all vehicle components immediately.
NOTICE

Diesel
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Vehicles with a diesel engine must be run on diesel ⇒. If you use diesel with a high sulphur
content, the service intervals are shorter ⇒ Service. Information on countries that use diesel with a
high sulphur content is available from your Volkswagen dealership.
The fuel quality affects the running properties, performance and service life of the engine. You
should therefore use fuel that already contains suitable service additives if possible ⇒.
Information on the fuel standards can be found in the chapter on fuel standards ⇒ Fuel standards.
Winter-grade diesel fuel and filter preheater system
Winter-grade diesel fuel, which can be used at temperatures below -20°C (-4°F), is available during
the cold months. In countries with different climates, diesel for other temperature conditions is
usually available. Information is available from your Volkswagen dealership and filling stations in
the respective country.
Diesel vehicles are equipped with a filter pre-heater system. When using winter-grade diesel fuel,
the fuel system is safe for operation at temperatures down to around -24°C (-11°F).
However, if the fuel has waxed to such an extent that the engine will not start at temperatures
below -24°C (-11°F), place the vehicle in a heated garage or workshop for a while ⇒.
At cold temperatures, louder noises may occur in the diesel engine and the exhaust gas may
be tinged blue.
Refuelling
Fig. 195 Behind the tank flap: tank cap.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
See the chapter on technical data for information on filling capacities ⇒ Fuel tank capacity.
Incorrect refuelling or unsuitable fuel additives may cause damage to the vehicle.
•Before refuelling, check whether the fuel standard information provided on the pump
conforms to the requirements of the vehicle.
•Use only Volkswagen-approved service additives in the approved quantity.
•If, in an emergency, you have to use petrol with an octane number lower than the
recommended number, drive at medium engine speeds and avoid high engine loading.
Avoid high engine speeds and heavy engine loads. Failure to do so can result in engine
damage. Fill the tank with petrol with the correct octane number as soon as possible.
NOTICE
Start boosters may explode or suddenly cause the engine to run at high revs. This can
cause injuries or damage to the engine.
•Never use a start booster.
WARNING
Incorrect refuelling can lead to damage to the vehicle.
•Before refuelling, check whether the fuel standard information provided on the pump
conforms to the requirements of the vehicle.
•Do not refuel with RME fuel, petrol, fuel oil or other unsuitable fuels.
•Use only Volkswagen-approved service additives in the approved quantity.
NOTICE

Refuelling process
•Unlock the tank flap with the vehicle key or the button in the driver door.
•Open the tank flap.
•Unscrew the tank cap and place it in the holder on the tank flap.
•The fuel tank is full when the properly operated automatic filler nozzle clicks off for the first time
⇒.
•Screw the tank cap onto the filler neck.
•Close the tank flap.
Misfuelling prevention device
Fig. 196 In the tank filler neck: misfuelling prevention device.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The tank filler neck in diesel vehicles can be fitted with a misfuelling prevention device ⇒ Fig. 196.
The misfuelling prevention device ensures that the vehicle can be refuelled only using diesel pump
nozzles.
Turn the diesel nozzle to and fro if the misfuelling prevention device gets stuck. This can open the
misfuelling prevention device and make it possible to refuel the vehicle. If the misfuelling prevention
device remains closed, proceed to a qualified workshop to have the system checked.
If it is necessary to refuel the vehicle using a spare fuel canister in the event of an emergency, the
misfuelling prevention device will not open. In order to fill the tank with fuel, pour the diesel into the
tank extremely slowly in very small quantities.
