Cleaning and caring for your vehicle
188Cleaning the engine compartment
Take special care when cleaning the engine compartment.Anti-corrosion treatment
The engine compartment and the surface of the power unit are given anti-
corrosion treatment at the factory.
Good corrosion protection is particularl y important in winter when the car is
frequently driven on salted roads. To prevent the salt corroding the vehicle,
the entire engine compartment should be thoroughly cleaned before and
after the salting period.
Your Authorised Service Centre is able to provide the correct cleaning and
preserving products and has the necessary equipment. For this reason, we
recommend having this work performed by them.
The anti-corrosion protection is usually removed if the engine compartment
is cleaned with grease removing solutions, or if you have the engine cleaned.
If this job is carried out, you should ensure that all surfaces, seams, joints and
components in the engine compartmen t are given anti-corrosion treatment
afterwards.
WARNING
•
When working in the engine compartment, always observe the safety
warnings ⇒ page 198.
•
Switch off the engine, apply the parking brake firmly and always
remove the key from the ignitio n before you open the bonnet.
•
Allow the engine to cool before you clean the engine compartment.
• Do not c l ean the underside of vehicle wheel arches without protecting
your hands and arms. You may cut your self on sharp-edged metal parts.
Failure to comply could result in injury.
•
Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident. If possible, avoid sudden braking immediately after washing
the vehicle.
•
Never touch the radiator fan. It is temperature-controlled and could
start automatically, even when the key is removed from the ignition!For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed.
The polluted water must be cleaned in an oil separator. For this reason,
engine washing should be carried out only by a qualified workshop or a suit-
able filling station.Care of the vehicle interiorCleaning plastic parts and the dash panel– Use a clean, damp cloth to clean plastic parts and the dash panel.
– If this does not provide satisfactory results, use a special solvent-free plastic cleaning product.
WARNING
Never clean the dash panel and surface of the airbag module with cleaners
containing solvents. Solvents cause the surface to become porous. If the
airbag inflates, disintegrating plastic parts can cause substantial injuries.

Accessories, parts replacement and modificationsAccessories and partsAlways consult an Authorised Service Centre before
purchasing accessories and parts.Your vehicle is designed to offer a high standard of active and passive safety.
Before purchasing accessories and parts, and before making technical
changes to your car, we recommend that you consult your Authorised Service
Centre.
SEAT dealerships will be happy to provide you with the latest information
about the use, legal requirements and recommendations from the manufac-
turer regarding accessories and parts.
We recommend you use only SEAT Approved Accessories
® and SEAT
Approved Spare Parts
®. This way, SEAT can guarantee that the product in
question is suitable, reliable and safe. Authorised Service Centres have the
necessary experience and facilities to ensure that parts are installed correctly
and professionally.
Despite continuous observation of the market, SEAT is not able to assess the
reliability, safety and suitability of parts not approved by SEAT. For this reason
SEAT cannot assume responsibility for any non-genuine parts used, even if
these parts have been approved by an official testing agency or are covered
by an official approval certificate.
Any equipment subsequently installed which has a direct effect on the
vehicle and/or the way it is driven (e.g. cruise control system or electronically-
controlled suspension) must be approved by SEAT for use in your vehicle and
bear the e mark (the European Union's authorisation symbol).
If any additional electrical components are fitted which do not serve to
control the vehicle itself (for instance a refrigerator box, laptop or ventilator fan, etc.), these must bear the
CE mark (European Union manufacturer
conformity declaration).
WARNING
Accessories, for example telephone holders or drink holders, should never
be fitted on the covers of, or within the working range of, the airbags. If
they are, there is a danger of resulting injury if the airbag is triggered in an
accident.ModificationsModifications must always be carried out according to our
specifications.Unauthorised modifications to the electr onic components or software in the
vehicle may cause malfunctions. Due to the way the electronic components
are linked together in networks, other systems may be affected by the faults.
This can seriously impair safety, lead to excessive wear of components, and
also invalidate your vehicle registration documents.
SEAT Authorised Service Centres cannot be held liable for any damage
caused by modifications and/or work performed incorrectly.
For this reason, we recommend that all work should be performed by an
Authorised Service Centre using genuine and SEAT
® approved parts and
accessories .

Tips and Maintenance
Te c h n i c a l D a t a
Checking and refilling levelsRefuellingThe fuel cap cover opens automatically with the central
locking system. The tank holds approximately 55 litres.Unscrewing the tank cap
– Lift the lid.
– Unscrew the cap, turning it anti-clockwise.
Closing the tank cap
– Screw the tank cap to the right, until the point of feeling a “click”.
– Close the drawer. Make sure you hear it click into place. The tank
cap is secured with an anti-loss attachment
The tank flap is at the rear of the vehicle on the right.
If the automatic filler nozzle is operated correctly, it will switch itself off as
soon as the tank is “full”. Never attempt to fill beyond this point, as this will
fill the expansion chamber. Fuel may le ak out if ambient conditions are warm.
The correct fuel grade for your vehicle is given on a sticker on the inside of the
fuel tank flap, where further notes on fuel can be found.
Releasing the fuel tank flap by hand
If the central locking system fails, the fuel tank flap can be opened manually
as follows:•
Open the tailgate
•
Remove the cover from the right side trim in the luggage compartment.
•
Insert a hand and pull the locking device back
•
Open the cap and take out the plug.
WARNING
•
Fuel is highly inflammable and can cause serious burns and other inju-
ries.
−Never smoke or use any naked flame when filling the fuel tank of the
vehicle, or a spare fuel canister, with fuel. This is an explosion hazard.
− Follow legal requirements for the use of spare fuel canisters.
− For safety reasons we do not recommend carrying a spare fuel
canister in the vehicle. The canister could be damaged in an accident
and leak.
•
If, in exceptional circumstances, you have to carry a spare fuel canister,
please observe the following points:

− Never fill the spare fuel canister inside the vehicle or on it. An elec-
trostatic charge could build up during filling, causing the fuel fumes to
ignite. This may be fatally explosive. Always place the canister on the
ground to fill it.
− Insert the fuel nozzle into the mouth of the canister as far as
possible.
− If the spare fuel canister is made of metal, the filling nozzle must be
in contact with the canister during filling. This helps prevent an electro-
static charge building up.
− Never spill fuel in the vehicle or in the luggage compartment. Fuel
vapours are explosive. Danger of death.Caution
•
Fuel spills should be removed from the paintwork immediately.
•
Never run the tank completely dry. An irregular fuel supply could cause
misfiring. As a result, unburnt fuel could enter the catalytic converter and
cause damage.For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has switched off;
this may cause the fuel to overflow if it becomes warm.
PetrolPetrol types
The correct petrol 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 Norm”).
Petrol types are categorised according to their octane number, e. g. 91, 95,
98 RON (RON = “research octane number”). You may use petrol with a higher
octane number than the one recommended for your engine. However, this
has no advantage in terms of fuel consumption and engine power.
Caution
•
Even one full tank of leaded fuel would 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 reason you should use good quality petrol

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.
