210PetrolPetrol types
The recommended fuel types are listed on a sticker inside the
fuel tank flap.Only unleaded petrol, corresponding to the standard DIN EN 228 , may be
used for vehicles with catalytic converters (EN = “European Standard”).
Fuel types are differentiated by the octane rating, e.g: 91, 95, 98 RON (RON
= “Regulation Octane Number, unit for determining the knock resistance of
petrol”). You may use petrol with a high er octane number than the one recom-
mended for your engine. However, this has no advantage in terms of fuel
consumption and engine power.
The correct fuel type for your vehicle is given in the technical table for the
engine. Section “Technical Data”
Caution
•
Petrol that follows EN 228 may be mixe d with small quantities of ethanol.
However, the so-called “bioethanol fuels” available at commercial establish-
ments, e.g. with reference E50 or E85, which contain a high percentage of
ethanol, may not be used, as they will damage the fuel system.
•
Even one tankful of leaded fuel woul d permanently impair the efficiency
of the catalytic converter.
•
High engine speed and full throttle can damage the engine when using
petrol with an octane rating lower than the correct grade for the engine.For the sake of the environment
Just one full tank of leaded fuel would seriously impair the efficiency of the
catalytic converter.
Petrol additives
Petrol additives improve the quality of the petrol.The quality of the petrol influences running behaviour, performance and
service life of the engine. For this re ason, you should use good quality petrol
containing additives. These additives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from building up in the engine.
If good quality petrol with additives is not available or engine problems occur,
the required additives must be added during refuelling.DieselDiesel*Diesel fuel must correspond to DIN EN 590 (EN = “European standard”). It
must have a cetane number (CN) of at least 51. The cetane number indicates
the ignition quality of the diesel fuel.
Notes on refuelling ⇒page 208.Biodiesel*The biodiesel fuel must comply wi th the DIN EN 14.214 (FAME) Standard.•
Biodiesel is a methylester obtained from rapeseed oil.
•
DIN is the German abbreviation for “ Deutsches Institut für N ormung e.V.”,
the German standards institute.
•
EN means European Norm.
•
FAME is the English abbreviation for “F atty Acid Methyl Ester”.

Oil propertiesViscosity
The viscosity class of the oil is selected according to the diagram.
When the ambient temperature falls outside the limits of the scale for a short
period, an oil change is not required.
Mono-grade oil
Single grade oils are generally not suitable for all year round use, due to
ranges of viscosity
3). These oils are only useful in a climate that is constantly very cold or very
warm.
Engine oil additives
No type of additive should be mixed with the engine oil. The deterioration
caused by these additives is not covered by the warranty.
Note
Before a long trip, we recommend findin
g an engine oil that conforms to the
corresponding VW specifications and keeping it in the vehicle. This way, the
correct engine oil will always be available for a top-up if needed.Checking the oil level

Caution
•
The oil level must never be above area . This could damage the cata-
lytic converter or the engine. Contact a specialist garage to drain the engine
oil if necessary.
•
No additives should be used with engine oil. Any damage caused by the
use of such additives would not be covered by the factory warranty.For the sake of the environment
•
Oil must not be disposed of into the drains or onto the ground.
•
Always observe legal requirements when disposing of empty oil
canisters.
Cooling systemLiquid coolant
The purpose of the liquid coolant is to carry heat away from
the engine. The correct amount of antifreeze is decisive in
preventing the cooling system from freezing in winter.The your vehicle's engine cooling system is filled for life at the factory, so no
coolant needs to be changed. The liquid coolant consists of a mixture of water
and anti-freeze G12++. This is a glycol-b ased antifreeze with anti-corrosion
additives.
Liquid coolant additive
The amount of antifreeze required depends on the temperatures to be
expected in the winter season. If the antifreeze concentration is too low the
coolant can freeze, resulting in failure of the cooling system and heater. The cooling system is filled at the fact
ory with the correct amount of anti-
freeze for the country concerned.
In most cases, the mixture consists of 60% water and 40% anti-freeze. This
mixture gives the required anti-freeze protection at temperatures down to
-25°C and particularly protects the metal parts of the cooling system against
corrosion. It also prevents scaling and significantly raises the boiling point of
the liquid coolant.
Countries with warm climate
The liquid coolant concentration must not be reduced by adding plain water,
even in the summer or in warm climates. The concentration of the anti-freeze
must always be at least 40%.
Countries with cold climate
If greater frost protection is required in very cold climates, the proportion of
the anti-freeze G12++ can be increased. A concentration of 60% offers anti-
freeze protection of temperatures down to approx. -40°C. However,the
concentration of anti-freeze must not exceed 60%, as the anti-freeze protec-
tion would then drop and the performance of the coolant system would suffer.
Vehicles for countries with cold clima tes (e.g. Sweden, Norway and Finland)
have factory-filled anti-freeze protection for temperatures down to -35°C. In
these countries, the concentration of anti-freeze should always be at least
50%.
Caution
•
It is advisable to have the cooling system checked before the winter
season to make sure that the antifreeze concentration is adequate for the
conditions to be expected. This applies particularly if you intend to take the
car into a colder climate zone. If necessary, have the antifreeze concentration
increased to 50 - 60% as required.
•
Use only anti-freeze G12++ , an additive meeting the “TL-VW 774G” spec-
ification. Other anti-freezes may give considerably inferior corrosion protec-

218tion. The damage caused by the use of these anti-freezes may lead to a loss
of liquid coolant, causing serious damage to the engine.•
The anti-freeze G12++ can be mixed on ly with anti-freeze additives G11,
G12 and G12+.
Checking the liquid coolant level
The liquid coolant level can be checked at a glance.– Switch the ignition off.
– Check the coolant level on liquid coolant expansion tank ⇒fig. 167. When the engine is cold, it should be between the
“min” and “max” marks. When the engine is hot, it may be
slightly above the “max” mark.Its location is shown in the correspon ding general overview of the engine
compartment. The liquid coolant level should be checked with the engine switched off.
The liquid coolant level is monitored
by a warning lamp in the instrument
panel ⇒ page 77. However, we recommend that it should be checked occa-
sionally.
Liquid coolant losses
Any loss of liquid coolant normally indicates a leak in the cooling system. In
this case the cooling system should be inspected by a specialist garage
without delay. It is not sufficient merely to top up the liquid coolant.
If there are no leaks in the system, a loss of liquid coolant can only occur if
the coolant boils and is forced out of the system as a result of overheating.
Caution
Radiator sealants must not be added to the liquid coolant. Such additives
could seriously impair the function of the cooling system.Topping up the liquid coolant
Be careful when topping up with liquid coolant.– Switch the engine off.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒fig. 167 with a cloth, an d
carefully unscrew the cap anti-clockwise ⇒ .
– Add liquid coolant.
– Screw on the cap tightly.
