Your Authorised Service Centre can also be consulted to know if the vehicle
has been prepared for biodiesel use.
Things to note about RME fuel (biodiesel)
•The performance of a vehicle using biodiesel maybe somewhat reduced.•Fuel consumption of a vehicle using biodiesel may be slightly higher.•RME fuel is resistant to the cold down to approx. -10°C.•At temperatures below -10°C, we recommend using winter diesel fuel.•Your vehicle is designed to be refuelled with up to a maximum of 7%
blended biodiesel, in accordance with the DIN 51628 standard.Caution
•RME fuel can damage the fuel system in vehicles which are not suitably
adjusted.•If you refuel with biodiesel, please be sure that it conforms to the
DIN E 14.214 standard.•If you use biodiesel that does not meet the required standard, the fuel
filter could become clogged.Note
•In case of low exterior temperatures and a fuel biodiesel percentage of
higher than 50%, an increase in gas emission may occur during operation of
the independent heating.•The fuel filter may become clogged when fuel is changed to biodiesel. For
this reason, we recommend you that, when having run 300 or 400 km after a
fuel change, the fuel filter change must also be done. Also note the instruc-
tions in the Inspection and Maintenance plan.•If the vehicle is to remain parked for more than about two weeks, we
recommend filling the fuel tank with biodiesel and driving about 50 km in
order to avoid damage to the injection system.
Winter driving
Diesel can thicken in winter.Winter-grade diesel
When using summer-grade diesel fuel, difficulties may be experienced at
sub-zero temperatures because the fuel thickens due to wax separation.
Therefore, winter-grade diesel fuel is available in some countries during the
cold months. It can be used at temperatures as low as -22°C.
In countries with different climatic conditions the diesel fuel generally sold
has different temperature characteristics. Check with an Authorised Service
Centre or filling stations in the country concerned regarding the type of diesel
fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter pre-heater, making it well equipped for
operation in winter. This ensures that the fuel system remains operational to
approx. -24°C, provided you use winter-grade diesel which is safe to -15°C.
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24°C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (“thinners”, or similar additives) with diesel fuel.

lever in neutral. If you are driving an automatic vehicle, place the selector
lever in the position P.•Wait for the engine to cool down.•Children should not be allowed to approach the engine compartment•Never spill liquids involved in vehicle operations on the engine
compartment, as these may catch fire (e.g. anti-freeze containing liquid
coolant).
•Take care not to cause short circuits in the electrical system, especially
when working on the battery.•Never touch the radiator fan while the engine is hot, as the fan could
start up suddenly.•Never open the expansion tank when the engine is hot. The cooling
system is under pressure.•Protect face, hands and arms from any hot steam or hot liquid coolant
released by covering the cap with a large, thick rag when opening the
expansion tank.•If any tests have to be performed with the engine running, there is an
extra safety risk from the rotating parts, such as the drive belts, alternator
and radiator fan, etc., and from the high-voltage ignition system.•Observe the following additional warnings if work on the fuel system or
the electrical system is necessary:
−Always disconnect the battery.
− Do not smoke.
− Never work near open flames
− Always keep an approved fire extinguisher immediately available.Caution
When topping up fluids, make sure the correct fluid is put into the correct
filler opening. This can otherwise cause serious malfunctions or engine
damage.
For the sake of the environment
Inspect the ground underneath your vehicle regularly so that any leaks are
detected at an early stage. If you find spots of oil or other fluids, have your
vehicle inspected in the garage.

•Vehicles with a diesel particulate filter must only b e fille d with VW 507 00
engine oil.•Avoid mixing this oil with other engine oils.•Only in exceptional circumstances, if the engine oil level is too low
⇒ page 230 and you cannot obtain the oil specified for your vehicle, can you
put in a small quantity of oil (once) conforming to the VW 506 00, VW 506 01,
VW 505 00, VW 505 01 or ACEA B3 / ACEA B4 specification. (up to 0.5l).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

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 finding 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.

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-based 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 factory 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-

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 ⇒page 232, fig. 181 with a
cloth, and carefully unscrew the cap anti-clockwise ⇒.
– Add liquid coolant.
– Screw on the cap tightly.Make sure that the liquid coolant meets the required specifications
⇒page 231, “Liquid coolant”. Do not use a different type of anti-freeze if
anti-freeze G12++ is not available. In this case, use only water and bring the
anti-freeze concentration back up to the correct level as soon as possible.
Always top up with new liquid coolant. Do not fill above the “max” mark. Excess liquid coolant is forced out of the
system through the valve in the filler cap when the engine gets hot.
If a lot of liquid coolant has been lost, wait for the engine to
cool down before
putting in cold coolant. Failure to do so could result in serious engine
damage.
WARNING
•The cooling system is under pressure. Do not unscrew the cap on the
expansion tank when the engine is hot. Failure to comply could result in
burns.•The anti-freeze and liquid coolant can be a health hazard. Therefore,
the anti-freeze should be stored in the original container in a safe place out
of reach of children. Failure to comply could result in poisoning.For the sake of the environment
Drained off coolant should not be used again. Drain off the used coolant into
a suitable container and dispose of it in the proper manner (observe environ-
mental regulations).Radiator fan
The radiator fan can start running spontaneously.The auxiliary fan can continue to run for as long as 10 minutes after stopping
the engine – even after the ignition is switched off. It may also start running
suddenly ⇒ after some while if•stored heat raises the coolant temperature, or•the hot engine compartment is additionally heated up by the sun.

Brake fluidChecking the brake fluid level
The brake fluid level can be checked at a glance.The brake fluid level must be between the “Min” and “Max” ⇒fig. 187 mark-
ings.
The fluid level may drop slightly after a period of time due to the automatic
compensation for brake pad wear. This is quite normal.
H owe ve r, if th e le ve l goes d own not icea bly i n a short time, or drops below the
“Min” mark, there may be a leak in the brake system. If the fluid level in the
reservoir is too low, this will be indicated by the brake warning lamp
⇒ page 70 and ⇒page 77. If this should happen, take the car to a qualified
workshop immediately and have the brake system inspected.
