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. For
this reason, 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 a Technical Service 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 glow plug system, 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 that 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 products) with diesel fuel. Bonnet

WARNING (Continued)
● If any tests have to be performed with the engine running, there is an
added safety risk from the rotating parts (e.g. drive belts, alternator, ra-
diator 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 at the workshop.
● When the external temperature and level of humidity are high or when
the engine stops, it is possible for water to drop from the air conditioning
system evaporator potentially forming a small puddle on the ground. This is
normal and does not indicate a leak.
Note
On right-hand drive vehicles some of the reservoirs mentioned below are lo-
cated on the other side of the engine compartment. Closing the bonnet
–
To close the bonnet, push it down until it overcomes the spring
pressure.
– Let the bonnet engage in the locking part. Do not force it ⇒ 
.
WARNING
● For safety reasons the bonnet must always be completely closed
when the vehicle is moving. After closing it always check that it is proper-
ly secured. The bonnet must be flush with the adjacent body panels.
● Should you notice that the bonnet is not safely secured when the ve-
hicle is moving, stop the vehicle immediately and close the bonnet. Fail-
ure to do so could result in an accident.

Engine oil General notes
The engine is factory-filled with a special multi-grade oil that can be used all
year round.
As the use of high quality oil is essential for the correct operation of the en-
gine and its long useful life, when topping up or replacement is necessary
use only those oils that conform to the requirements of the VW standards.
The specifications (VW standards) set out in the following page should ap-
pear on the container of the service oil; when the container displays the
specific standards for petrol and diesel engines together, it means that the
oil can be used for both types of engines. 

Coolant fluid loss
Any loss of coolant fluid normally indicates a leak in the cooling system. In
this case the cooling system should be inspected by a specialised work-
shop without delay. It is not sufficient merely to top up the coolant fluid.
If there are no leaks in the system, a loss of coolant fluid 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 coolant fluid. Such additives
could seriously impair the function of the cooling system. 
Topping up the coolant fluid
Be careful when topping up with coolant fluid. – Switch the engine off.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒ Fig. 182 with a cloth,
and carefully unscrew the cap anticlockwise ⇒ 
.
– Add coolant fluid.
– Screw on the cap tightly.
Make sure that the coolant fluid meets the required specifications
⇒  page 238. Do not use a different type of antifreeze if G12++antifreeze is
not available. In this case, use only water and bring the antifreeze concen-
tration back up to the correct level as soon as possible.
Always top up with new coolant fluid. Do not fill above the “max” mark. Excess coolant fluid is forced out of the
system through the valve in the filler cap when the engine gets hot.
If a lot of coolant fluid has been lost, wait for the engine to
cool down before
putting in cold coolant. Failure to do so could result in serious engine dam-
age.
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 antifreeze and coolant fluid can be a health hazard. Therefore,
the antifreeze 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 in-
to a suitable container and dispose of it in the proper manner (observe envi-
ronmental regulations). 
Radiator fan
The radiator fan can start running spontaneously. The auxiliary fan can continue to run for as long as 10 minutes after stop-
ping the engine, even after the ignition is switched off. It may also start run-
ning suddenly ⇒ 
after some while if
● Stored heat raises the coolant temperature, or
● The hot engine compartment is additionally heated up by the sun. 

A highly explosive mixture of gases is released when the bat-
tery is under charge.
Keep children away from acid and batteries!
WARNING
Always be aware of the danger of injury and chemical burns as well as
the risk of accident or fire when working on the battery and the electrical
system:
● Wear eye protection. Protect your eyes, skin and clothing from acid
and particles containing lead.
● Battery acid is very corrosive and caustic. Wear protective gloves and
eye protection. Do not tilt the batteries. This could spill acid through the
vents. Rinse battery acid from eyes immediately for several minutes with
clear water. Then seek medical care immediately. Neutralise any acid
splashes on the skin or clothing with a soapy solution, and rinse off with
plenty of water. If acid is swallowed by mistake, consult a doctor immedi-
ately.
● Fires, sparks, open flames and smoking are prohibited. When han-
dling cables and electrical equipment, avoid causing sparks and electro-
static charge. Never short the battery terminals. High-energy sparks can
cause injury.
● A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated room
only.
● Keep children away from acid and batteries.
● Before working on the electrical system, you must switch off the en-
gine, the ignition and all consumers. The negative cable on the battery
must be disconnected. When a light bulb is changed, you need only
switch off the light.
WARNING (Continued)
● Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alarm will otherwise be triggered.
● When disconnecting the battery from the vehicle electrical system,
disconnect first the negative cable and then the positive cable.
● Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never re-
verse the polarity of the connections. This could cause an electrical fire.
● Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery which
has frozen. A flat battery can also freeze at temperatures close to 0°C.
● Ensure that the vent hose is always connected to the battery.
● Never use a defective battery. This could cause an explosion. Replace
a damaged battery immediately.
CAUTION
● Never disconnect the battery if the ignition is switched on or if the en-
gine is running. This could damage the electrical system or electronic com-
ponents.
● Do not expose the battery to direct sunlight over a long period of time,
as the intense ultraviolet radiation can damage the battery housing.
● If the vehicle is left standing in cold conditions for a long period, protect
the battery from freezing. If it freezes it will be damaged. 
Charging the battery
A fully-charged battery is important for reliable starting. – Note the warnings ⇒

If and when
Spare steel rim wheel
The spare steel rim wheel is carried in the wheel well under
the floor panel in the luggage compartment. It is only inten-
ded for temporary use over short distances.
Fig. 195 Spare steel rim
wheel
Taking out the spare wheel
– Turn the plastic knob ⇒ Fig. 195 anticlockwise.
– Take out the spare wheel.
Securing the defective wheel in the spare wheel well
– Place wheel in spare wheel well in the luggage compartment.
– Secure the wheel by turning plastic knob clockwise.
– Replace the floor panel before closing the rear lid.
Your vehicle can be factory-equipped with a spare steel wheel. The spare
wheel does not usually meet the same performance standards as the wheels fitted on the vehicle because of the wheel/tyre dimensions, rubber
composition, tread pattern, etc. Therefore, note the following restrictions:
●
The spare steel wheel is designed only for your vehicle model. Do not
attempt to mount the wheel on any vehicle but your own.
● Your vehicle will have different driving characteristics when the spare
steel rim wheel is mounted ⇒ 
.
● The spare wheel is only intended for temporary use after having a flat
tyre. Replace the spare wheel with a normal wheel that has the proper tyre
dimensions as soon as possible.
● If the size of the spare steel rim wheel is different to that of the other
wheels, it is unlikely that snow chains suitable for the other wheels will fit it.
WARNING
● After mounting the spare steel rim wheel, the tyre pressure must be
checked and corrected as soon as possible. The tyre pressure must corre-
spond to the vehicle load (consult the table containing the inflation pres-
sures). Otherwise there is danger of causing an accident. Use the highest
tyre pressure as indicated in the table.
● Do not drive faster than 80 km/h, as higher speeds can cause an acci-
dent.
● Avoid heavy acceleration, hard braking and fast cornering, as this
could cause an accident.
