Trailer towingTrailer towingTe c h n i c a l r e q u i r e m e n t s
The towing bracket must meet certain technical requirements.Your vehicle is intended mainly for transporting passengers and luggage.
However, if suitably equipped, it can also be used to tow a trailer or caravan.
If your vehicle has been factory-supplied with a towing bracket, all of the
necessary technical and legal aspects for trailing towing have been taking
into account during manufacturing.
Your vehicle is fitted with a 13-pole socket for the electrical connection
between the trailer and the vehicle. If the trailer has a 7-pole connector you
can use an adapter cable. This can be purchased at an Authorised Service.
If a towing bracket is to be fitted after the vehicle is purchased, this must be
done according to the instructions of the towing bracket manufacturer
⇒ page 212.
WARNING
If a towing bracket is retrofitted, the installation should be carried out by a
qualified workshop.•Particularly in high outdoor temperatures, it is not possible to drive up
long steep gradients without a suitable cooling system. The engine would
heat up.•Incorrect installation can result in a safety risk!
Notes on towing
There are a number of points which need to be checked before
towing a trailer or caravan.– Observe the maximum permitted trailer weights ⇒page 301.Trailer weight
Never exceed the maximum permitted trailer weight.
If you do not load the trailer up to the maximum permitted trailer weight, you
can then climb correspondingly steeper gradients.
The maximum trailer weights listed are only applicable for altitudes up to
1000 m above sea level. With increasing altitude the engine power and there-
fore the vehicle's climbing ability are impaired because of the reduced air
density. The maximum trailer weight has to be reduced accordingly. The
weight of the vehicle and trailer must be reduced by about 10% for every
subsequent 1000 m (or part thereof). This figure refers to the combined
weight of the (loaded) vehicle and (loaded) trailer.
The figures for the drawbar load that appear on the identification plate of the
towing bracket are for certification purposes only. The correct figures for your
specific model, which may be lower than these figures for the towing bracket,
are given in the registration documents and on ⇒page 294. Also refer to
⇒ page 301.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them
moving.

Fitting a towing bracket
•Driving with a trailer involves an extra effort for the vehicle. Therefore,
before fitting a towing bracket, please contact an Authorised Service Centre
to check whether your cooling system needs modification.•The legal requirements in your country must be observed (e.g. the fitting
of a separate warning lamp).•Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securi ng bolts must be tightened using a
torque wrench, and a power socket must be connected to the vehicle's elec-
trical system. This requires specialised knowledge and tools.•Figures in the illustration show the elevation value and the attachment
points which must be considered if you are retrofitting a towing bracket.WARNING
The towing brackets should be fitted at a specialised workshop.
•If the towing bracket is incorrectly installed, there is serious danger of
accident.•For your own safety, please observe the instructions provided by the
manufacturer of the towing bracket.Caution
•If the power socket is incorrectly installed, this could cause damage to the
vehicle's electrical system.Note
For the Sport finish, fitting a trailer bracket is not recommended due to the
design of the bumpers.

230•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 coolant fluid
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
added safety risk from the rotating parts (e.g. drive belts, alternator, radi-
ator 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.
Note
On right-hand drive vehicles some of the reservoirs mentioned below are
located 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 properly
secured. The bonnet must be flush with the adjacent body panels.•Should you notice that the bonnet is not safely secured when the
vehicle is moving, stop the vehicle immediately and close the bonnet.
Failure to do so could result in an accident.
Engine oilGeneral notesThe engine comes with a special, high quality, multi grade oil that can be
used in all seasons of the year except for those regions affected by extreme
cold.

– Carefully put in the specified grade of oil ⇒page 231, adding
0.5 litres at a time.
– After two minutes, check the oil level once again ⇒page 232.
– Where necessary, add more engine oil.
– Replace the oil filler cap carefully and push the dipstick all the way in.
WARNING
•When refilling with oil, make sure no oil falls onto hot engine parts.
Failure to comply could result in fire.•Wash your skin thoroughly if it comes into contact with engine oil.
Caution
•The oil level must never be above area . This could damage the cata-
lytic converter or the engine. Contact a qualified workshop 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 in the drain or on the ground.•Always observe legal requirements when disposing of empty oil
canisters.Cooling systemCoolant fluid
The purpose of the coolant fluid 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 vehicle's engine cooling system is filled for life at the factory, so no
coolant needs to be changed. The coolant fluid consists of a mixture of water
and antifreeze G12++. This is a glycol-based antifreeze with anti-corrosion
additives.
Coolant fluid 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.

Checking and refilling levels
234The 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% antifreeze . This
mixture gives the required antifreeze 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 coolant fluid.
Countries with warm climate
The coolant fluid concentration must not be reduced by adding plain water,
even in the summer or in warm climates. The concentration of the antifreeze
must always be at least 40%.
Countries with cold climate
If greater freeze protection is required in very cold climates, the proportion of
G12++ antifreeze can be increased. A concentration of 60% offers antifreeze
protection of temperatures down to approx. -40 °C. However, the concentra-
tion of antifreeze must not exceed 60% , as the antifreeze protection would
then drop and the performance of the coolant system would suffer.
Vehicles for countries with cold climates (e.g. Sweden, Norway and Finland)
have factory-filled antifreeze protection for temperatures down to -35 °C. In
these countries, the concentration of antifreeze 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
vehicle into a colder climate zone. If necessary, have the antifreeze concen-
tration increased to 50 - 60% as required.•Use only G12++ antifreeze, an additive meeting the “TL-VW 774G” spec-
ification. Other antifreezes may give considerably inferior corrosion protec- tion. The damage caused by the use of these antifreezes may lead to a loss of
coolant fluid, causing serious damage to the engine.
•G12++ antifreeze can be mixed only with antifreeze additives G11, G12
and G12+.Checking the coolant level
The coolant level can be checked visually.– Switch the ignition off.
– Check the coolant level on coolant fluid expansion tank ⇒fig. 179 . 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 corresponding general overview of the engine
compartment.

Checking and refilling levels235
Safety First
Operating Instructions
Practical Tips
Technical Specifications
The coolant level should be checked with the engine switched off.
The coolant level is monitored by a warning lamp on the instrument panel
display
⇒page 78. However, we recommend that it should be checked occa-
sionally.
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 qualified workshop
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. 179 with a cloth, and
carefully unscrew the cap anti-clockwise ⇒.
– Add coolant fluid.
– Screw on the cap tightly.
Make sure that the coolant fluid meets the required specifications
⇒page 233, “Coolant fluid”. Do not use a different type of antifreeze if
G12++ antifreeze is not available. In this case, use only water and bring the
antifreeze concentration 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
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 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 into
a suitable container and dispose of it in the proper manner (observe environ-
mental regulations).
