WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and causing
injury.
Note
•
By law, the ball coupling must be removed if a trailer is not being towed
and it obscures the number plate.
Driving tips
Driving with a trailer always requires extra care.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason it is advisable not to drive at the maximum permissible speed in
unfavourable road, weather or wind conditions. This applies especially when
driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of snaking . Never try to stop the “snaking” by increasing speed.
Always brake in good time. If the trailer has an overrun brake, apply the
brakes gently at first and then firmly. This will pr event the jerking that can be
caused by the trailer wheels locking. Select a low gear in good time before
going down a steep descent. This enables you to use the engine braking to
slow down the vehicle. Heating
At very high temperatures and during prolonged ascents, driving in a low gear
and high engine speed, always moni
tor the temperature indicator for the
coolant ⇒page 55.
Electronic Stabilisation Program*
Do not switch off the ESP* when towing a trailer. The ESP* makes it easier to
stabilise if the trailer starts to snake.
Driving economically and with respect for the
environmentGeneral notes
Fuel consumption depends largely on your personal driving
style.Fuel economy, environmental impact and wear on the engine, brakes and
tyres depend largely on three factors:•
Personal driving style
•
Conditions of use (weather, road surface)
•
Technical requirements
By adopting an economical driving style and anticipating the traffic situation
ahead, you can easily reduce fuel consumption by 10-15%. This section
suggests methods of lessening the impact on the environment and reducing
your operating costs at the same time.

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. 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 sold generally
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.
Working in the engine compartmentSafety instructions on working in the engine compartment
Any work carried out in the engine compartment or on the
engine must be carried out cautiously.Before starting any work on the engine or in the engine compart-
ment:
1. Switch off the engine and remove the key from the ignition.
2. Apply the handbrake.
3. Move the gear stick to neutral or the selector lever to position P.
4. Wait for the engine to cool down.
5. Keep children away from the vehicle.
6. Raise the bonnet ⇒page 200.You should not do any work in the engine compartment unless you know
exactly how to carry out the jobs and have the correct tools! Have the work
carried out by a qualified workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs and
batteries, are being constantly developed . SEAT provides a constant flow of
information to the Authorised Service Centres concerning modifications. For
this reason we recommend that you have service fluids and consumables
replaced by an Authorised Service Centre. Please observe the relevant
instructions ⇒page 191. The engine compartmen t of any motor vehicle is a
hazardous area ⇒.

Tips and Maintenance
Te c h n i c a l D a t a
WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger of injury and scalding as well as the risk
of accident or fire.•
Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwis e, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the
engine to cool before carefully opening the bonnet.
•
Switch off the engine and remove the key from the ignition.
•
Apply the handbrake and move the gear stick to neutral or selector
lever to position P.
•
Keep children away from the vehicle.
•
Never touch hot engine parts. There is a risk of burns.
•
Never spill liquids on a hot engine or on a hot exhaust gas system. This
is a fire hazard.
•
Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached ⇒page 249. The battery could
explode.
•
Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!
•
Do not unscrew the cap on the expansion tank when the engine is hot.
If the coolant is hot, the cooling system will be pressurised!
•
Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.
•
Always make sure you have not left any objects, such as cleaning cloths
and tools, in the engine compartment.
•
If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
•
If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belts, alternator, radiator fan, etc., and
from the high-voltage ignition system. You should also observe the
following points:
−Never touch the electrical wiring of the ignition system.
− Ensure that jewellery, loose cl othing and long hair do not get
trapped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
− Always think carefully about pressing the accelerator if a gear is
engaged in either an automatic or manual gearbox. The vehicle could
move, even if the handbrake is applied. Danger of death.
•
If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following sa fety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
− Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.Caution
When changing or topping up service fluids, make absolutely certain that you
fill the fluids into the correct reservoirs. Failure to observe this point will result
in serious malfunctions and engine damage!

•
Wait until no more steam, smoke or coolant is emitted from the bonnet,
then carefully open the bonnet.
•
When working in the engine compartment, always observe the safety
warnings ⇒ page 198.
Closing the bonnet– Raise the bonnet slightly.
– Release the bonnet stay and replace it in its support.
– At a height of about 30 cm let it fall so it is locked.If the bonnet does not close, do not pr ess downwards. Open it once more and
let it fall as before.
WARNING
If the bonnet is not closed properly, it could open while you are driving and
completely obscure your view of the road. Risk of accident.•
After closing the bonnet, always check that it is properly secured. The
bonnet must be flush with the surrounding body panels.
•
If you notice that the bonnet latch is not secured when the vehicle is
moving, stop the vehicle immediately and close the bonnet properly. Risk
of accident.
Engine oilEngine oil specifications
The engine oil used must conform with exact specifications.Specifications
The 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.
As the use of high quality oil is essential for the correct operation of the
engine 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.
If it is not possible to find oil co nforming to the VW standards then oil
conforming to the ACEA or API standa rds with an appropriate viscosity at
atmospheric temperature should be used instead. The use of this type of oil
may have some repercussions on the performance of the engine for example,
long starting time, increased consumption and a higher emission level.
If a top up is required then different oils may be mixed as long as they all
conform to the VW standards.
The specifications (VW standards) set out in the following page should
appear on the container of the service oil; the container will display together
the different standards for petrol and diesel engines, the oil can be used for
both types of engines.

WARNING
•
The coolant additive is toxic. There is a toxic risk. Always keep the
coolant additive in the original container which should be stored out of the
reach of children. The same applies to coolant that you have drained off.
•
The coolant additive G 12+ must be added in sufficient quantities to
provide anti-freeze protection at the coldest ambient temperatures that
can be expected. At extremely cold ambient temperatures, the coolant
could freeze, causing the vehicle to breakdown. As the heater would also
not work in this situation, there is a risk of suffering exposure!Caution
•
Other additives may give considerably inferior corrosion protection. The
resulting corrosion in the cooling system can lead to a loss of coolant,
causing serious damage to the engine.
•
The coolant additive G 12+ (purple) ca n be mixed with the additive G 12
(red) or G 11. Never mix G12 (red colour) with G 11.
Checking the coolant level and topping up

The correct coolant level is important for fault-free func-
tioning of the engine cooling system.Before opening the bonnet, read and observe the warnings ⇒ in
“Safety instructions on working in the engine compartment” on
page 198.
Opening the coolant expansion tank
– Switch off the engine and allow it to cool.
– To prevent scalding, cover the cap on the expansion tank with a thick cloth and carefully unscrew the cap ⇒.
Checking coolant level
– Look into the open coolant expansion tank and read the coolant level.
