Description and function of the airbags
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The airbags can protect vehicle occupants during frontal and side collisions by reducing their
movement in the direction of the collision.
When an airbag is triggered, it is inflated by a gas generator. This causes the airbag covers to
break, and the airbags inflate forcefully to cover their deployment zones within milliseconds. Once a
vehicle occupant wearing a seat belt starts to sink into the inflated airbag, the gas inside the airbag
starts to escape to cushion the occupant and slow down their movement. This can reduce the risk
of severe and fatal injuries. A triggered airbag will not always prevent other injuries from occurring,
such as swelling, bruising, burning and grazing. The deployment of the airbag can also produce
frictional heat.
Airbags provide no protection for the arms or lower body. Exception: in vehicles with a knee airbag,
the knee area of the driver will be protected.
The most important factors for triggering the airbag are the type of accident, the angle of impact,
the vehicle speed and the type of object with which the vehicle collides. Therefore, visible damage
to the vehicle does not always mean that the airbag should have been triggered.
Whether or not the airbag triggers is determined by the vehicle deceleration rate caused by the
collision and registered by the electronic control unit. If this rate is below the reference value
programmed into the control unit, the airbags will not be triggered, even though the vehicle may be
badly damaged as a result of the collision. Vehicle damage, repair costs or even the lack of vehicle
damage in an accident do not necessarily give an indication of whether an airbag should inflate or
not. It is not possible to define a range of vehicle speeds and reference values, since the
circumstances will vary considerably between one collision and another. It is therefore impossible to
cover every possible kind and angle of impact that would trigger the airbags. Important factors in
the triggering of the airbag include the nature (hard or softyfRIWKHREMHFWWKDWWKHYHKLFOHKLWVWKH
angle of impact, and the vehicle speed.
Airbags only serve as a supplement to the three-point seat belt in some accident situations when
the vehicle braking is sufficient to trigger the airbags. Airbags can only be triggered once and only
in certain situations. The seat belts are always there to provide protection in situations in which the
airbags are not triggered or have already been triggered. For example, if the vehicle collides with a
further vehicle following the initial collision, or is hit by another vehicle.
The airbag system is part of the vehicle's overall passive safety concept. The airbag system can
only work effectively when the occupants are wearing their seat belts correctly and have assumed a
proper sitting position ⇒ Sitting position.
Components of the vehicle safety concept

•During rear collisions.

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

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°Fyf.
However, if the fuel has waxed to such an extent that the engine will not start at temperatures
below -24°C (-11°FyfSODFHWKHYHKLFOHLQDKHDWHGJDUDJHRUZRUNVKRSIRUDZKLOH ⇒.
At cold temperatures, louder noises may occur in the diesel engine and the exhaust gas may
be tinged blue.
Refuelling

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

The refill bottle must be disposed of in accordance with regulations governing the protection
of the environment.
Catalytic converter
First read and observe the introductoryinformation and safety warnings⇒
Introduction
To help ensure long-term functionality in the exhaust system and the catalytic converter:
•Use unleaded petrol only ⇒ Fuel types and refuelling.
•Do not allow the fuel tank to run completely empty.
•Do not overfill engine oil ⇒ Engine oil.
•Do not tow start the vehicle. Use jump leads ⇒ Jump starting.
If you notice misfiring, uneven running or loss of power when the vehicle is moving, reduce speed
immediately. The vehicle should be inspected at the nearest qualified workshop
⇒ Troubleshooting. If this happens, 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 if the emission purification system is
working properly.
Particulate filter

Safety notes for working in the engine compartment
Always park the vehicle on a level and stable surface before carrying out any work in the engine
compartment.
The engine compartment of a motor vehicle is a hazardous area. You should only carry out work on
the engine, and in the engine compartment, if you know exactly how to perform the required tasks,
are aware of the general safety procedures and have access to the correct equipment, service
fluids and suitable tools. Failing to carry out work correctly can cause serious injuries ⇒. The
work should be carried out by a qualified workshop if you are uncertain. Volkswagen recommends
using a Volkswagen dealership for this purpose.
Unintentional vehicle movements during service work can cause serious injury.
•Never work underneath a vehicle if it is not secured against rolling away. If you are
working underneath the vehicle while the wheels are on the ground, the vehicle must
be on a level, the wheels chocked, and the vehicle key removed from the ignition lock
as required.
•If you have to work underneath the vehicle, use suitable stands to provide extra
support for the vehicle. The vehicle jack is not sufficient for this task and can fail,
which can lead to serious injuries.
•The start/stop system must have been deactivated.
WARNING
The engine compartment of any motor vehicle is a dangerous area. Serious injuries can be
sustained here.
•The utmost care and attention must be paid when carrying out any work and you must
follow the general safety rules. Never take any risks.
•Never do any work on the engine or in the engine compartment unless you know
exactly how to carry it out. If you are uncertain of what to do, the work should be
carried out by a qualified workshop. Serious injuries can result from work that has not
been carried out properly.
•Never open the bonnet if you see steam or coolant escaping from the engine
compartment. Hot steam or hot coolant can cause serious burns. Always wait until you
can no longer see or hear steam or coolant coming from the engine compartment.
•Always allow the engine to cool down before opening the bonnet.
•Hot parts of the engine or exhaust system can burn the skin.
•Observe the following points before opening the bonnet once the engine has cooled
down:
- Switch on the electronic parking brake and move the selector lever to position P
or move the gear lever to the neutral position.
- Switch off the ignition and remove the vehicle key from the ignition lock.
- Always keep children away from the engine compartment and never leave the
vehicle unattended.
•The cooling system is under pressure when the engine is hot. Never open the cap of
the coolant expansion tank when the engine is hot. Coolant may spray out and cause
serious burns and other injuries.
- Slowly and carefully turn the cap on the coolant expansion tank anticlockwise
while exerting gentle downward pressure on the cap.
- Always protect the face, hands and arms from hot coolant or steam with a large,
thick cloth.
•When refilling, do not spill any service fluids on engine components or on the exhaust
system. The spilt service fluids can start a fire.
WARNING
High voltages in the electrical system can cause electric shocks, burns, serious injuries
and death!
•Never short circuit the electric system. The 12-volt battery could explode.
•Please note the following guidelines to help reduce the risk of an electric shock and
serious injuries while the engine is running or being started:
- Never touch the electrical wiring of the ignition system.
- Never touch the electrical wiring and connections of gas discharge bulbs.
