NOTICE

Using fuel that does not comply with the applicable standards and are not approved may reduce performance and cause damage to

the engine and fuel system.

● Only refuel with fuels of the specified grades that comply with the fuel information label in the tank flap.

Petrol grades

The fuel information label in the fuel filler flap provides information on the fuel to be refuelled.

Petrol grades differ with respect to their Research Octane Number (RON). The vehicle may also be filled with petrol that has a higher

RON than the engine requires. However, this does not provide any advantage in terms of fuel consumption or engine output.

The fuel information label may show several petrol grades (e.g. RON 95 min. 91). The highlighted octane number – RON 95 in the

example – is the preferred petrol grade for which the vehicle has been designed and optimised The petrol grade listed as an alternative

– RON 91 in the example – can be used for refuelling only if the preferred grade – RON 95 in the example – is not available.

Only refuel petrol engine vehicles with metal-free petrol (without lead, manganese or iron) that does not have a higher ethanol content

than stated on the fuel information label →

.

The fuel quality affects the running properties, performance and service life of the engine. Refuel with fuel that already contains

suitable fuel additives →

.

In some regions, e.g. North America, Central America and South America, fuels are offered in special fuel grades. Volkswagen

recommends using “TOP TIER detergent gasoline” for the specified countries. Information on “TOP TIER detergent gasoline” is

available on the official website:

https://www.toptiergas.com

NOTICE

Incorrect refuelling or unsuitable fuel additives can cause damage to the vehicle.

● Only refuel with fuels of the grades that comply with the fuel information label in the tank flap.

● Refuel only with petrol that has the specified or a higher RON.

● Use only Volkswagen-approved service additives in the approved quantity if necessary.

NOTICE

If petrol fuel with too low an octane number is filled in an emergency, engine damage can occur if the vehicle is driven with a high

engine load.

● Only run the engine at medium speeds and with a low engine load.

● Refuel with petrol with the correct octane number as soon as possible.

The fuel information label in the fuel filler flap provides information on the fuel to be refuelled.

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. Suitably qualified workshops can provide information on

countries that use diesel with a high sulphur content. Volkswagen recommends using an authorised Volkswagen repairer.

The fuel quality affects the running properties, performance and service life of the engine. Refuel with fuel that already contains

suitable service additives →

.

Winter-grade diesel fuel and filter preheater system

Diesel fuel with improved cold flow properties (winter-grade diesel fuel) must be used during the winter months. Refuelling with

winter-grade diesel fuel can prevent malfunctions in vehicle operation. Winter-grade diesel fuel is available at filling stations during

the winter months.

Different climate- and time-dependent cold classes may be defined in country-specific fuel standards → Diesel.

Diesel vehicles are equipped with a filter preheater system. The filter preheater system guarantees the cold flow properties of the

diesel fuel when driving. Information on the cold properties of diesel is available from filling stations in the respective country.

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.

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. After you have

checked that you are using the correct fuel nozzle, turn the diesel fuel nozzle back and forth slightly while exerting 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 suitably qualified workshop and have the system checked. Volkswagen recommends using an authorised Volkswagen

repairer.

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 fuel tank despite this, pour the diesel into the tank extremely slowly in very small quantities. Use a suitable adapter

for the spare fuel canister in order to make refuelling easier. The relevant adapters are available from a suitably qualified workshop.

Volkswagen recommends using an authorised Volkswagen repairer.

WARNING

Incorrect refuelling can lead to fire, serious or fatal injuries and vehicle damage.

● Before refuelling, check whether the fuel standard specified on the pump meets the vehicle’s requirements.

● Do not refuel with pure RME fuel, petrol, fuel oil or other unsuitable fuels.

● Use only Volkswagen-approved service additives in the approved quantity.

At cold temperatures, louder noises may occur in the diesel engine and the exhaust gas may be tinged blue.

.

Do not continue filling the tank after it switches off. The expansion space in the fuel tank can fill with fuel, e.g. if it heats up. This could

cause fuel to overflow or automatic venting may not function .

WARNING

Overfilling the fuel tank may cause the fuel to splash out and overflow. This could cause explosions, fires and serious or fatal injuries.

● Do not continue refuelling when the filler nozzle switches off for the first time.

NOTICE

If the fuel tank content is not consumed up to the reserve quantity at regular intervals, this may result in the fuel quality and system

functions necessary for vehicle operation not being maintained.

● You should therefore refuel at least every six months, but only when the indicator lamp lights up.

Fuels can pollute the environment. Collect any service fluids that escape or are spilled and dispose of them correctly.

The components relevant to emission control reduce harmful emissions:

®

—AdBlue (→ AdBlue).

—Catalytic converter (→ Catalytic converter).

—Particulate filter (depending on equipment) (→ Particulate filter).

—Maintenance .

WARNING

Toxic gases can enter the vehicle interior if the engine runs in closed spaces. This can cause serious injuries and lead to death by

suffocation.

● Do not allow the engine to run in enclosed spaces.

● Do not leave the vehicle unattended if the engine is running.

WARNING

The components of the exhaust system become very hot and can ignite highly flammable materials, e.g. undergrowth, leaves, dry

grass or spilt fuel. This can lead to a fire and cause serious or fatal injuries.

—Only use fuel that has been approved for the vehicle.

—Do not run the fuel tank empty (→ Fuel types and refuelling).

—Do not overfill engine oil (→ Engine oil).

—Do not tow-start the vehicle. Use jump leads (→ Jump starting).

If you notice misfiring, loss of power or uneven running when driving, reduce speed immediately and have the vehicle checked by a

suitably qualified workshop . Volkswagen recommends using an authorised Volkswagen repairer. Otherwise unburned fuel can enter

the exhaust system and escape into the environment. The catalytic converter can also be damaged by overheating.

The emissions may have a sulphur-like smell even if the emission purification system is working properly.

Function

The particulate filter is dependent on the vehicle equipment and filters out soot particles in the exhaust gas.

Regeneration

In normal vehicle operation, the filter cleans itself. If it is not possible for the filter to clean itself, for example, if the vehicle is only ever

used for short trips, the filter will become saturated with soot. The diesel particulate filter requires cleaning (regeneration).

Noises, slight smells and increased engine speeds may occur during regeneration. The radiator fan may run on while the vehicle is

moving or when the engine has been switched off.

To assist the regeneration of the particulate filter, Volkswagen recommends that you avoid making frequent short journeys.

The soot in the particulate filter is burnt off at high temperatures on a periodic basis. During the periodic regeneration process,

the yellow indicator lamp

does not light up.

Irregular engine running and faults

Irregular engine running or faults when driving may be a sign of poor fuel quality.

1. Reduce speed immediately.

2. Drive to the nearest suitably qualified workshop at medium engine speeds and low loads on the engine. Volkswagen

recommends using an authorised Volkswagen repairer.

3. If these symptoms occur immediately after refuelling, switch off the engine immediately to avoid any subsequent damage.

4.

Seek expert assistance.

Particulate filter clogged with soot

The indicator lamp lights up yellow.

The particulate filter is saturated with soot and requires regeneration.

Prerequisite for regeneration trip: the engine is at operating temperature.

For petrol engines

1.0 l to 1.8 l

1. Drive at a speed between around 50 km/h and 120 km/h (around 30 mph and 75 mph).

The achieved temperature increase can burn the soot off the filter.

2. End the regeneration drive only when the indicator lamp goes out.

3. Go to a suitably qualified workshop without delay if the indicator lamp continues to light up after driving for approximately

40 minutes. Volkswagen recommends using an authorised Volkswagen repairer.

2.0 l and 3.0 l

1. Drive at a speed of at least 80 km/h (around 50 mph).

2. To allow the vehicle to coast while a gear is engaged, take your foot off the accelerator completely for a few seconds.

3. Repeat this procedure (accelerate and coast) until the indicator lamp goes out.

4. If the indicator lamp does not go out after some time, go immediately to a suitably qualified workshop. Volkswagen recommends

using an authorised Volkswagen repairer.

For diesel engines

1. Drive at a speed between around 50 km/h and 120 km/h (around 30 mph and 75 mph).

The achieved temperature increase can burn the soot off the filter.

2. End the regeneration drive only when the indicator lamp goes out.

3. Go to a suitably qualified workshop without delay if the indicator lamp continues to light up after driving for approximately

40 minutes. Volkswagen recommends using an authorised Volkswagen repairer.
