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

Natural gas
Natural gas can be delivered in compressed or liquefied form.

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.

The electrolyte level of the vehicle battery should be checked regularly in high-mileage vehicles, in
hot countries and in older vehicle batteries. The vehicle battery is otherwise maintenance-free.

recommends that the protective coating on the underside of the vehicle and on the running gear
should be checked regularly and repaired if necessary.
Cleaning the engine compartment
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The engine compartment of any motor vehicle is a hazardous area ⇒ Preparation for working in the
engine compartment.
The engine compartment should be cleaned by a qualified workshop. An incorrect cleaning
procedure could possibly remove corrosion protection and damage electrical components.
Furthermore, water could enter the vehicle interior directly via the plenum chamber ⇒.
If the engine compartment is very dirty, we recommend that you always proceed to a qualified
workshop to have it cleaned by a professional mechanic. Volkswagen recommends using a
Volkswagen dealership for this purpose.
Plenum chamber
The plenum chamber is located in the engine compartment between the windscreen and the engine
and has a perforated cover. Air from outside is drawn in from the plenum chamber and is passed
into the vehicle interior via the heating and air conditioning system.
Leaves and other loose objects must be removed from the cover of the plenum chamber at regular
intervals using a vacuum cleaner or by hand.
In the interests of environmental protection, the engine compartment should be washed only
in specially provided wash bays. This prevents toxic waste water containing oil, grease and fuel
from entering the sewerage system. In some districts, washing the engine compartment anywhere
else may be prohibited.
Cleaning and caring for the interior

⇒ Cleaning and caring for natural leather covers
⇒ Cleaning leatherette upholstery
⇒ Cleaning stowage compartments, drink holders and ash trays
⇒ Cleaning and caring for the dash panel, wooden trims and plastic parts

careful. This is not caused by a fault in the upholstery, but by the non-colourfast nature of the
garments.
Leaving stains, dirt and other deposits on the surface of vehicle components and cloth seat covers
for a long time can make it difficult to clean and treat them. Stains, dirt and deposits may become
impossible to remove, particularly if left for a long time.

Turn the light switch to position 0 Lights.
Shift the turn signal lever to neutral Lights.
Automated manual gearbox: move the selector lever to D or R Changing gear.

Manual gearbox: select a gear Changing gear.
Leave the defective bulbs to cool down.
Check to see if a fuse has blown Fuses.
Follow the instructions to change the affected bulb . Always use identical bulbs with the
same designation. The designation is inscribed on the bulb, either on the glass part or on
the base.
Do not touch the glass part of the bulb with unprotected fingers. The heat of the bulb would
cause the fingerprint to evaporate and condense on the reflector. This will impair the
brightness of the headlight.
After changing the bulb, check to ensure that the bulb is working properly. If the bulb is not
working properly, the bulb may not have been inserted properly or may have failed again,
or the connector may have been inserted incorrectly.
Any time you change a bulb in the front of the vehicle, the headlight settings should be
checked by a qualified workshop.
