The belt tensioners are activated by sensors during severe frontal, side and rear collisions. They
tighten the seat belts against the direction in which they are pulled. A loose seat belt is retracted,
which can reduce the forward movement or the movement of the vehicle occupants in the direction
of the impact. The belt tensioner works together with the airbag system. If the side airbags are not
activated, the belt tensioner will not be activated if the vehicle rolls over.
A fine dust may be produced when the airbags are triggered. This is quite normal and does not
mean that there is a fire in the vehicle.
Belt tension limiter
The belt tension limiter reduces the pressure exerted by the seat belt on the body during an
accident.
All safety requirements must be observed when the vehicle or components of the system are
scrapped. Qualified workshops are familiar with these requirements ⇒ Service and disposal of belt
tensioners.
Service and disposal of belt tensioners
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Seat belts may become damaged during any work on the belt tensioners or while removing or
refitting any vehicle parts in conjunction with any other repair work. This damage will not always be
noticeable. The consequence may be that the belt tensioners could function incorrectly, or not
function at all, in the event of an accident.
Regulations must be observed to ensure that the effectiveness of the belt tensioner is not reduced
and that removed parts do not cause any injuries or environmental pollution. Qualified workshops
are familiar with these requirements.
The airbag modules and belt tensioners may contain perchlorate. Please comply with
legislation regarding disposal.

 Introduction
This chapter contains information on the followingsubjects:
⇒ Types of front passenger front airbag system
⇒ Indicator lamps
⇒ Description and function of the airbags
⇒ Front airbags
⇒ Switching the front passenger front airbag on and off manually using the key-operated switch
⇒ Side airbags
The vehicle is equipped with a front airbag for the driver and front passenger. The front airbags can
provide front seat occupants with additional chest and head protection if the seat, seat belts, head
restraints and, in the case of the driver, steering wheel are adjusted and used correctly. Airbags are
meant only for additional protection. The airbags are not a substitute for seat belts. Seat belts must
always be worn, even when the front seats are equipped with front airbags.

Introduction
Windscreen wiper response in various situations:
When the vehicle is
stationary:
When switched on, the wipers will temporarily be switched to the next
setting down.
When the interval wipe is
switched on:
The wiper intervals are adjusted depending on the vehicle speed.
The faster the vehicle is travelling, the shorter the interval.
The wiper will try to wipe away any obstacles that are on the windscreen. The wiper will stop
moving if the obstacle blocks its path. Remove the obstacle and switch the wiper back on again.

Information on the brakes
First read and observe the introductoryinformation and safety warnings⇒
Introduction
New brake pads cannot generate the full braking effect during the first 200 to 300 km and must first
be run in ⇒. However, you can compensate for the slightly reduced braking force by applying
more pressure to the brake pedal. During the run-in period, the braking distance is longer when
the brakes are depressed fully or during emergency braking than with brakes that have been fully
run in. In the run-in period, the brakes should not be depressed fully and situations that create a
heavy load on the brakes should be avoided. For example, when driving too close to the vehicle
ahead.
The rate of wear of the brake pads depends to a great extent on the conditions under which the
vehicle is operated and the way in which the vehicle is driven. With regular urban trips, short
journeys and a sporty driving style, the brake pads must be checked by a qualified workshop more
regularly than stated in the service schedule.
When driving with wet brakes, for example after driving through water, after heavy rainfall or after
washing the vehicle, the braking effect may be delayed as the brake discs will be wet, or possibly
iced up (in winteryf7KHEUDNHVPXVWEHGULHGDVTXLFNO\DVSRVVLEOHE\FDUHIXOEUDNLQJDWKLJKHU
speed. Please ensure that no following vehicle and no other road user is put at risk as a result of
this action ⇒.
Any layer of salt accumulated on the discs and pads will delay the braking effect and increase the
braking distance. If the brakes on the vehicle have not been applied for a long time on roads that
have been gritted with salt, the layer of salt must be reduced through careful braking ⇒.
Corrosion on the brake discs and dirt in the brake pads are facilitated through long periods of
inactivity, low mileage and low load levels. If the brake pads have been hardly used, or if they are at
all corroded, Volkswagen recommends that the brake discs and brake pads be cleaned by braking
strongly several times from high speed. Please ensure that no following vehicle and no other road
user is put at risk as a result of this action ⇒.
Fault in the brake system
A brake circuit may have failed if you have to reduce speed and the vehicle does not brake as
normal (sudden increase in braking distanceyf7KLVLVLQGLFDWHGE\WKHZDUQLQJOLJKW . Go to the
nearest qualified workshop immediately to have the fault corrected. Drive at low speed when doing
this and anticipate much longer braking distances and an increase in the pressure required on the
pedal.
Brake servo
The brake servo will only function when the engine is running and reinforces the pressure applied
by the driver on the brake pedal.
If the brake servo is not functioning or the vehicle is being towed, the brake pedal will have to be
depressed more forcefully as the braking distance will be increased due to the lack of assistance for
the brake system ⇒.
The components of the exhaust system become very hot. This can cause fires and serious
injuries.
\f

Before using a particular brake fluid, check that the specifications printed on the container
correspond to the vehicle requirements.
Brake fluid that is compliant with VW standard 501 14 is available from Volkswagen dealerships.
If this brake fluid is not available and it is necessary to use another high-quality brake fluid instead,
brake fluid that is compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116 DOT 4 can
be used.
Not all brake fluids that are compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116
DOT 4 have the same chemical composition. Some of these brake fluids may contain chemicals
that can damage or destroy brake system components over time.
Volkswagen therefore recommends the use of brake fluid that is compliant with
VW standard 501 14 to ensure sustained optimal operation of the brake system.
Brake fluid that is compliant with VW standard 501 14 fulfils the requirements of DIN ISO 4925
CLASS 4 or US standard FMVSS 116 DOT 4.
Brake fluid level
The brake fluid level must always be between the MIN and MAX marking on the brake fluid
container or above the MIN marking ⇒.
The brake fluid level cannot be checked accurately in all models as engine components may
partially conceal the brake fluid container. If the brake fluid level cannot be read exactly, please
proceed to a qualified workshop.
The brake fluid level drops slightly when the vehicle is being used as the brake pads wear and the
brakes are automatically adjusted.
Changing the brake fluid
The brake fluid must be changed as indicated in the service schedule ⇒BookletService schedule,.
The brake fluid should be changed by a qualified workshop. Volkswagen recommends using a
Volkswagen dealership for this purpose. Only brake fluid that conforms with the required
specification should be used.
Brake fluid can pollute the environment. Any spilt service fluids must be cleaned up and
disposed of properly.
Brake failure or reduced braking effect can be caused by the brake fluid level being too low or
by brake fluid that is too old or unsuitable.

Fuel
 Introduction
This chapter contains information on the followingsubjects:
⇒ Petrol
⇒ Natural gas
Different engines require different fuels. The factory-fitted sticker on the inside of the tank flap
indicates the fuel type that is required for your particular vehicle.
Volkswagen recommends using low-sulphur or sulphur-free fuels, to help reduce fuel consumption
and prevent damage to the engine.
If the engine is not running smoothly or begins to judder, this can indicate poor or inadequate fuel
quality, e.g. water in the fuel. If these symptoms appear, reduce the vehicle speed immediately and
drive to the nearest qualified workshop at medium engine speeds, avoiding high engine loading. If
these symptoms occur immediately after the vehicle has been refuelled, switch the engine off as
soon as it is safe to do so and seek expert assistance. This can help to prevent further damage.

than the engine requires. However, this does not provide any advantage in terms of fuel
consumption or engine output.
Volkswagen recommends using fuel with a low sulphur content or sulphur-free fuel for petrol
engines in order to achieve reduced fuel consumption.
Petrol additives
The quality of petrol influences the running properties, performance and service life of the engine.
This is why the vehicle should be refuelled with good quality petrol that has only non-metallic
additives pre-added by the petroleum industry. These petrol additives help to prevent corrosion,
keep the fuel system clean, and prevent the build-up of deposits in the engine.
If good quality petrol containing non-metallic additives is not available, or if engine problems arise,
the necessary petrol additives must be added to the petrol when refuelling ⇒.
Not all petrol additives are effective. The use of unsuitable petrol additives can cause considerable
damage to the engine and catalytic converter. Metallic additives should be avoided at all times.
Petrol additives on sale that are intended to improve knock resistance or increase the octane
number can also contain metallic additives ⇒.
Volkswagen recommends genuine Volkswagen or Audi fuel additives for petrol engines. These
additives and information on how to use them are available from your Volkswagen dealership.
Natural gas engines
Run the petrol tank empty every 6 months until the indicator lamp  lights up. This is necessary to
maintain the required system function for petrol mode and fuel quality.
Natural gas
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Natural gas
Natural gas can be delivered in compressed or liquefied form.
Liquefied Natural Gas (LNGyfLVSURGXFHGE\UDSLGFRROLQJRIWKHQDWXUDOJDV7KLVGHFUHDVHVWKH
volume considerably in comparison to Compressed Natural Gas (CNGyf$YHKLFOHHTXLSSHGZLWKD
natural gas engine may not be refilled directly with liquefied natural gas as the gas would expand
too much once in the tank in the vehicle.
Vehicles fitted with a natural gas engine may therefore only be refilled and driven using
compressed natural gas ⇒.
Natural gas quality and consumption
Natural gas is available in two grades: H-gas and L-gas.
H-gas has a higher calorific value and a lower nitrogen and carbon dioxide content. The higher the
calorific value of the natural gas the lower the levels of consumption.
The calorific value and the nitrogen or carbon dioxide values may, however, vary within one quality
group. For this reason, the vehicle consumption may vary when using natural gas of the same
quality.
\f

Unintentional vehicle movements during service work can cause serious injury.
\f

Park the vehicle on a level and stable surface.
Depress and hold the brake pedal until the engine has stopped.
Apply the handbrake firmly Braking, stopping and parking.
Select the neutral position or move the selector lever to N Changing gear.
Stop the engine and remove the vehicle key from the ignition Starting and stopping the
engine.
Allow the engine to cool sufficiently.
Children and other people should be kept well away from the engine compartment.
Ensure that the vehicle cannot roll away unexpectedly.
Service fluids leaks are harmful to the environment. So you should regularly check the
ground underneath your vehicle. If there are spots of oil or other fluids on the ground, the vehicle
should be inspected by a qualified workshop. Any spilt service fluids must be disposed of properly.
