WARNING
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 stop working if the engine sputters
or goes off due to fuel shortage 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.

NOTICE
Do not run the tank empty. The irregular fuel supply can cause misfiring and allow unburnt fuel to
enter the exhaust system. The catalytic converter or particulate filter could be damaged as a result.

The small arrow next to the petrol pump symbol in the fuel gauge shows you the side of the vehicle
on which the tank flap is located.

NOTICE
Free access to the pedals must be ensured at all times. For example, a larger brake pedal travel will
be necessary in order to stop the vehicle if a brake circuit fails. The brake pedal will have to be
depressed further and harder than normal.

Currently selected gear.
Recommended gear.
Depending on the vehicle's equipment level, the instrument cluster display may indicate a gear
which should be selected to reduce fuel consumption while the vehicle is in motion.
Vehicles with DSG dual clutch gearbox: the selector lever must be in the Tiptronic position for
this ⇒ Changing gear using Tiptronic .
No recommended gear is indicated if the most suitable gear is already selected. The currently
selected gear is displayed.
Information on cleaning the particulate filter
The engine management system recognises when the particulate filter is becoming saturated and
supports regeneration of the filter by recommending the most suitable gear when driving. Compared
with normal driving, this may mean driving with an increased engine speed ⇒ Particulate filter .

CAUTION
The gear-change indicator is designed only to assist the driver and cannot replace the driver's own
judgement.
The driver has full responsibility for selecting the correct gear in all situations, e.g. when overtaking
or when driving up and down hills.

Driving in the correct gear can help to reduce fuel consumption.

The airbags and belt tensioners will not work if the ignition is switched off.
The brake servo will not work when the engine is switched off. More force is required on the brake
pedal to stop the vehicle.
If the vehicle key is removed from the ignition, the steering lock may activate and you will no longer
be able to steer the vehicle.

WARNING
The components of the exhaust system become very hot. This can cause fires and serious injuries.
Never park the vehicle so that parts of the exhaust system can come into contact with any
inflammable material underneath the vehicle, e.g. undergrowth, leaves, dry grass, spilt fuel etc.
Never apply additional underseal or anti-corrosion coatings to the exhaust pipes, catalytic
converters, heat shields or particulate filter.

NOTICE
If the vehicle has been driven at high load for a long period, the engine can overheat when it is
switched off. In order to avoid damage to the engine, allow the engine to run in neutral position for
approximately 2 minutes before switching it off.

After the engine is switched off, the radiator fan in the engine compartment may run on for some
minutes, even if the ignition is switched off or the vehicle key has been removed. The radiator fan
will switch itself off automatically.
Electronic immobiliser
The immobiliser helps to prevent the engine from being started and driven with an unauthorised
vehicle key.
There is a chip in the vehicle key. The immobiliser is automatically deactivated by this when a valid
vehicle key is inserted in the ignition lock.
The electronic immobiliser is automatically activated when the vehicle key is removed from the
ignition lock. In vehicles with Keyless Access, the vehicle key must be outside the vehicle.
The engine can be started only using a Volkswagen Genuine vehicle key with the correct code.
Coded vehicle keys are available from a Volkswagen dealership.

Problem-free operation of the vehicle is guaranteed only with Volkswagen Genuine vehicle keys.
Troubleshooting

The downhill speed control cannot hold the vehicle on the gradient in all situations or brake it
sufficiently on all slopes going downhill (e.g. if the ground is slippery or icy).

WARNING
Always be prepared to brake the vehicle. Accidents and injuries could occur if you are not prepared
to brake.
The downhill speed control is only a support function and may not be able to brake the vehicle
sufficiently in all situations when driving downhill.
The vehicle may become faster despite the downhill speed control being in operation.
Steering
Information on steering
The steering should be locked every time you leave the vehicle to make it more difficult for the
vehicle to be stolen.
The steering
The power steering is not hydraulic, but is an electromechanical system. The advantage of this
steering system is that no hydraulic hoses, hydraulic oil, pumps, filter or other parts are required.
The electromechanical system reduces fuel consumption. A hydraulic system requires constant oil
pressure in the system, whereas an electromechanical steering system only needs an energy supply
while steering.
In vehicles with driving profile selection, the selected driving profile can affect the behaviour of the
power steering ⇒ Driving profile selection and 4MOTION Active Control .
Electronic steering column lock in vehicles with a starter button
The steering column will be locked if the driver door is opened when the ignition is switched off. For
this, the vehicle should be stationary and, if necessary, the gear selector lever should be in position
P.
If the ignition is not switched off until after the driver door is opened, the electronic steering column
will only be locked when the vehicle is locked using the sensor in the door handle or the vehicle key.
Mechanical steering column lock (steering lock) in vehicles with an ignition lock
The steering column is locked if the vehicle key is removed from the ignition lock when the vehicle is
stationary. Turn the steering wheel slightly until the steering lock audibly engages.
Insert the vehicle key into the ignition lock to unlock the steering lock. Turn the steering wheel
slightly to relieve the load on the steering lock mechanism. Hold the steering wheel in this position
and turn the ignition on.

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. 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 you notice misfiring, loss of power or uneven running when driving, reduce speed immediately and
have the vehicle checked by a qualified workshop ⇒ Troubleshooting . Otherwise unburnt fuel can
enter the exhaust system and escape into the atmosphere. The catalytic converter can also be
damaged by overheating.

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

Periodic regeneration
The soot in the particulate filter is burnt off at high temperatures on a periodic basis.
To assist the regeneration of the particulate filter, Volkswagen recommends that you avoid making
only short journeys.
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.

During the periodic regeneration process, the yellow indicator lamp does not light up.
