drive at medium engine speeds and avoid high engine loading. Avoid high engine speeds and heavy
engine loads. Refuel with petrol with the correct octane number as soon as possible.
Diesel
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Fill vehicles with a diesel engine only with diesel or diesel with a maximum RME fuel content of 7 %
⇒ .
If you use diesel with a high sulphur content, the service intervals are shorter. Information on
countries where the diesel has a high sulphur content is available from your Volkswagen dealership
or a qualified workshop.
The fuel quality affects the running properties, performance and service life of the engine. Refuel
with fuel that already contains suitable service additives ⇒ .
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 with a different temperature behaviour
is offered. Information is available from your Volkswagen dealership, qualified workshops and filling
stations in the respective country.
Diesel vehicles are equipped with a filter preheater system. When using winter-grade diesel fuel, the
fuel system is safe for operation at temperatures down to around -24°C (-11°F). In order to ensure
that the vehicle can also be started at low outside temperatures, Volkswagen recommends parking
the vehicle in a location that is protected from the whether, e.g. in a garage ⇒ Troubleshooting .
Misfuelling prevention device
The tank filler neck in diesel vehicles may be fitted with a misfuelling prevention device. This is
intended to help ensure that the vehicle is refuelled only using diesel filler nozzles.
If the nozzle cannot be inserted correctly into the tank filler neck, first check whether you are using a
diesel filler nozzle. When you have made sure that you are using the correct filler nozzle, move the
diesel filler nozzle to and fro slightly with light pressure. This can open the misfuelling prevention
device and make it possible to refuel the vehicle. If the misfuelling prevention device still remains
closed, go to a qualified workshop and have the system checked.
If it is necessary to refuel the vehicle using a fuel canister in the event of an emergency, the
misfuelling prevention device will not open. In order to nevertheless fill the tank with fuel, pour the
diesel into the tank extremely slowly in very small quantities.

If the tyre pressure is too low, this will increase fuel consumption and tyre wear.

When new tyres are driven at high speeds for the first time, they can expand slightly and trigger a
one-off pressure warning.

Old tyres should be replaced only by tyres that have been approved by Volkswagen for the vehicle
type.

Do not rely solely on the tyre monitoring system. Check your tyres regularly to ensure that they are
properly inflated and have no signs of damage, such as punctures, cuts, cracks, and blisters. Remove
any objects that become embedded in the tyre tread but have not penetrated into the body of the
tyre itself.
Tyre Pressure Loss Indicator
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Functional description
The Tyre Pressure Loss Indicator uses data from the ABS sensors and other functions to compare the
speed of rotation and the rolling circumference of the individual wheels.
The rolling circumference can change:

The sticker provides the correct tyre pressure for approved tyres and is located either on the driver
door pillar ⇒ Fig. 195  or inside the tank flap.
The appearance of the sticker may differ between vehicles. It may include additional tyre sizes.
The wrong tyre pressure will have a negative effect on the vehicle handling and leads to high levels
of wear or even a burst tyre ⇒ . The correct tyre pressure is particularly important at high speeds.
Comfort tyre pressure
Depending on the vehicle, the tyre pressure sticker may show details of a comfort tyre pressure

increase when driving with comfort tyre pressure.

Tread depth
In most countries, the minimum tread depth required by law is 1.6 mm (measured in the tread
grooves next to the tread wear indicators); observe any differing country-specific regulations. The
tyres should have the same tread depth, at the minimum on each axle ⇒ .
Observe any country-specific legal requirements relating to the permissible minimum tread depths
for winter and all-year tyres.
