Petrol
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Vehicles with a petrol engine must be run on unleaded petrol. Fuels with a maximum ethanol
content of 10yb(\f can be used for refuelling ⇒.
The petrol grades differ with respect to the octane number. The vehicle may be filled with petrol that
has a higher octane number than the engine requires. However, this does not provide any
advantage in terms of fuel consumption or engine output.
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.
Incorrect handling of fuel can cause explosions, fire, serious burns and other injuries.
•Switch off the auxiliary heater⇒ Auxiliary heater and ventilation, the engine, the
ignition, your mobile phone and other wireless equipment while refuelling.
•Do not get into the vehicle to avoid electrostatic discharge.
•Make sure that the tank cap is closed properly and no fuel can escape.
•Comply with any relevant safety information and legislation concerning the handling of
fuels.
WARNING
Fuel may run out of the fuel canister. This could cause fire and injuries.
•Do not carry fuel canisters in the vehicle.
CAUTION
Incorrect refuelling can lead to damage to the vehicle.
•Only use fuels that have been approved for the vehicle.
•Do not use fuels containing metals and only use approved additives.
•Spilt fuel should be removed from all vehicle components immediately.

Engine oil
Introduction
This chapter contains information on the followingsubjects:
⇒ Engine oil specification
⇒ Changing the engine oil
⇒ Engine oil consumption
⇒ Checking the engine oil level and refilling the engine oil
⇒ Troubleshooting
Leaking or spilt engine oil can pollute the environment. Spilt service fluids must be collected
then disposed of properly and in an environmentally responsible way.
Engine oil specification
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The correct engine oil is important for the function and service life of the engine. A special high
quality multigrade oil has been filled at the factory and this can normally be used as an all-season
oil.
If possible, use only Volkswagen-approved engine oil ⇒. To comply with flexible oil change
service requirements, refill only with approved flexible service engine oil that meets the
corresponding VW standard. The engine oils listed are multigrade high-lubricity oils.
Engine oils are constantly being developed and improved. Volkswagen dealerships are kept up to
date on all innovations. Volkswagen therefore recommends having engine oil changes done by a
Volkswagen dealership.
The quality of the engine oil is not only tailored to the requirements of engines and exhaust gas
treatment systems, but also to fuel quality. Due to the way in which a combustion engine works,
engine oil always comes into contact with combustion residues and fuel, which has a knock-on
effect on the ageing process of the oil.
The quality of fuels can vary greatly between individual markets and this must be taken into account
when selecting the correct engine oil.
Never mix coolant additive or other unsuitable additives into the windscreen washer fluid.
These may leave an oily film on the screen, restricting the field of vision.
•Use clean, clear water (not distilled wateryfZLWKDZDVKHUIOXLGUHFRPPHQGHGE\
Volkswagen.
•A suitable anti-freeze agent should be added to the windscreen washer fluid if
necessary.
WARNING
•Never mix other cleaning agents with the cleaning agents recommended by
Volkswagen. This can cause the ingredients to separate and block the windscreen
washer jets.
•When topping up service fluids, please ensure that you pour the correct service fluids
into the correct openings. The use of incorrect service fluids could result in serious
malfunctions and engine damage.
NOTICE
Incorrect handling of engine oil can cause serious burns and other injuries.
•Always wear eye protection when handling engine oil.
•Engine oil is toxic and must be stored out of the reach of children.
•Engine oil must be kept in the closed original container. This also applies to used oil
until it is disposed of.
•Never use empty food containers, bottles or other containers to store engine oil as
other people may then drink the engine oil.
•Regular contact with engine oil can damage the skin. Skin that has been in contact with
engine oil should be washed thoroughly with water and soap.
•Engine oil becomes extremely hot when the engine is running and can scald skin
severely. Always allow the engine to cool down.
WARNING

The use of engine oils compliant with the VW 504 00, VW 507 00 and VW 508 00 specifications
requires a fuel quality compliant with EN 228 (petrolyfDQG(1GLHVHO\f, or fuel of an equivalent
quality. Engine oils compliant with VW 504 00, VW 507 00 and VW 508 00 are therefore
unsuitable for use in a large number of markets.
If the engine has been filled with engine oil in accordance with the standards W 502 00, VW 504 00
and VW 507 00, a sticker with the relevant information will be located on the lock carrier in the
engine compartment. Observe this information!

QI7, and only when fuel of a quality compliant with EN 228 (petrolyfDQG(1GLHVHO\f, or fuel of
an equivalent quality, is available in the particular country.
The engine oil VW 502 00 must be used if the fuel grade does not comply with EN 228.
Using VW 504 00 instead of VW 508 00 may cause the vehicle's emissions values to increase
slightly.
You can also check with a qualified workshop if you are unsure whether your vehicle is equipped
with a diesel particulate filter. Volkswagen recommends using a Volkswagen dealership for this
purpose.
Changing the engine oil
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The engine oil must be changed on a regular basis. Always observe the service intervals applicable
for your vehicle ⇒ Service.
The engine oil and filter change should be carried out by a qualified workshop due to the special
tools and knowledge required, this also applies to the disposal of used oil. Volkswagen
recommends using a Volkswagen dealership for this purpose.
Please read the notes on the service intervals ⇒ Service.
Additives in the engine oil can cause new engine oil to discolour quickly. This is normal and does
not mean that the engine oil should be changed more frequently.

•Do not add any additional lubricants to the engine oil. Any damage caused by the use
of such additives is not covered by the warranty.
•Only those engine oil specifications that have been approved for use with the engine
should be used. Using other engine oils can cause engine damage.
•Another engine oil can be used in the event of an emergency if the listed engine oils are
not available. To avoid damaging the engine, a maximum quantity of 0.5 litres of the
following engine oil may be used only once until the next oil change:
- Petrol engines: standards ACEAA3/B4 or API SN (API SMyf.
- Diesel engines: standards ACEA C3 or API CJ-4.

Vehicle care
Notes on vehicle care
Regular and expert care helps to maintain the value of the vehicle.
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.
For proper cleaning and care, Volkswagen recommends using Genuine care products that have
been matched to your vehicle. Consult a qualified workshop if you have any specific questions or if
vehicle parts are not listed.
1yf
Incorrect care and cleaning of vehicle parts can impair the safety features of the vehicle
and cause serious injury.
•Vehicle parts must be cleaned according to the manufacturer's instructions.
•Always use approved or recommended cleaning products.
•Do not use solvent-based cleaning products. Solvents can cause irreparable damage
to the airbag modules.
•Protect your hands and arms against parts with sharp edges, e.g. when cleaning the
underbody or the insides of the wheel housings.
WARNING
Dirty, misted or iced over windows reduce visibility and increase the risk of accidents and
severe injuries. This could impair the safety equipment of the vehicle.
•Only drive when you have a clear view through all windows.
•Do not treat the windscreen with water-repellent window coating agents. In
unfavourable conditions, they can cause increased dazzle.
