Vehicle maintenance and cleaning
etc. so a degree of care is required in everyday use and when looking after
the leather.
Dust and grit in the pores and seams can scratch and damage the surface. If
the vehicle is under solar radiation for long periods, the leather should be
protected to prevent it from fading. However, slight colour variations in
high-quality natural leather are normal.
CAUTION
● Do not use solvents, wax polish, shoe cream, spot removers or similar
products on leather.
● To avoid damage, stubborn stains should be removed by a specialised
workshop. 
Seat belt cleaning
A dirty belt may not work properly.
Check all seat belts regularly and keep them clean.
Seat belt cleaning
– Pull the dirty seat belt right out and unroll it.
– Clean dirty seat belts with a gentle soap solution.
– Allow it to dry.
– Do not roll the seat belt up until it is dry.
If large stains form on the belts, it will not retract correctly into the automat-
ic belt retractor.
WARNING
● Do not use chemical cleaning agents on the seat belts, as this can im-
pair the strength of the webbing. Ensure that seat belts do not come into
contact with corrosive fluids.
● Check the condition of the seat belts at regular intervals. If you notice
that the belt webbing, fittings, retractor mechanism or buckle of any of
the belts is damaged, the belt must be replaced by a specialised work-
shop.
● Do not attempt to repair a damaged seat belt yourself. The seat belts
must not be removed or modified in any way.
CAUTION
After cleaning, allow seat belts to dry completely before rolling them up.
Otherwise, the belt retractors could become damaged. 

Accessories, replacement of parts and modifications
WARNING
Incorrectly performed modifications or other kind of work on your vehicle
can lead to malfunctions and cause accidents.

Roof aerial*
The vehicle can be fitted with a foldable* and anti-theft* roof aerial, which
can be folded backwards, when, for example, going through an automatic
carwash.
To fold
Unscrew the aerial rod, tilting it backwards into a horizontal position and
then screw in again.
To return to working position
Continue in the reverse order to the previous instruction.
CAUTION
If an automatic car wash tunnel is used, before entering the tunnel, put the
aerial down parallel to the roof and do not tighten to avoid damage. 
Mobile telephones and two-way radios
You will require an external aerial for mobile phones and
two-way radios. SEAT has approved for your vehicle the use of mobile telephones and two-
way radios providing under the following conditions: ●
The correct installation of an external aerial,
● transmitting power of maximum 10 watts.
The optimal reach of the equipment is only achieved with an external aerial.
First consult your Technical Service if you wish to use a mobile telephone or
a two-way radio with a transmitting power output in excess of 10 watts.
Here you will receive information concerning the technical possibilities for
retrofitting this equipment.
Mobile telephones and two-way radios should be only fitted by a special-
ised workshop, for example a SEAT dealership.
WARNING
● Always concentrate primarily on driving. If you are distracted while
driving you could have an accident.
● Never attach the telephone mountings to the surfaces covering the
airbag units or within the range of the airbags. There is a high danger of
injury if the airbag is triggered.
● Using your mobile telephones or two-way radios in the vehicle with-
out an external aerial, electromagnetic radiation in the vehicle could ex-
ceed authorised limits. This also may occur to external aerials that have
not been correctly installed.
CAUTION
Failure to consider the above-mentioned conditions could cause the elec-
tronics to malfunction. The most common causes of faults are:
● no external aerial,
● external aerial incorrectly installed,
● transmitting power output in excess of 10 watts. 

Checking and refilling levels
Refuelling
The tank flap is released manually. The tank holds approxi-
mately 45 litres.
Fig. 127 Tank flap open
Opening the fuel tank cap
– Lift the lid.
– Hold the cap firmly with one hand, then insert the key into the
lock and rotate 180° to the left.
– Unscrew the cap, turning it anticlockwise.
Closing the fuel tank cap
– Screw the tank cap to the right, until the point of feeling a
“click”. –
Turn the key in the lock, without releasing the cap, clockwise
through 180°.
– Remove the key and close the flap until it clicks 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 fuel tank is “full”. Never attempt to fill beyond this point, as this
will fill the expansion chamber. Fuel may leak 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. 

Checking and refilling levels
WARNING
● Fuel is highly flammable and can cause serious burns and other inju-
ries.
–Never smoke or use an open flame when filling the fuel tank of the
vehicle, or a spare fuel canister, with fuel. This is an explosion haz-
ard.
– Follow legal requirements for the use of spare fuel canisters.
– For safety reasons we do not recommend carrying a spare fuel can-
ister in the vehicle. The canister could be damaged in an accident and
leak.
● If, in exceptional circumstances, you have to carry a spare fuel canis-
ter, 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 could cause an explosion. Always place the canister on
the ground to fill it.
– Insert the fuel nozzle into the mouth of the canister as far as possi-
ble.
– 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
electrostatic 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.
● When filling the fuel tank after having run it completely dry on a vehicle
with a diesel engine the ignition must be switched on for at least 30 sec-
onds without starting the engine. When you then start the engine it may take longer than normal (up to one minute) for the engine to start firing.
This is due to the fact that the fuel system has to purge itself of air before
starting.
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. 

Note
The four most common types of adapter in Europe are the ACME adapter 1,
the Dish Coupling adapter 2, the bayonet adapter 3 and the EURO adapt-
er 4. On the whole, we recommend you carry all four adapters in your vehi-
cle, as some countries use more than one type of filling system. The intro-
duction of a single system (Euronozzle) throughout Europe is being studied. 
LPG fuel
LPG is an alternative vehicle fuel and is a blend of propane and butane.
The success of LPG is due to the strict regulations concerning exhaust gas
emissions. Compared to other fossil fuels, LPG is characterised by its re-
duced emissions.
LPG quality and consumption
Quality requirements for LPG are regulated for all Europe in DIN EN 589 and
permit the use of LPG throughout Europe.
A difference is drawn between winter gas and summer gas. Winter gas has a
higher proportion of propane gas. As a result, the driving range of winter
gas may be lower (due to increased consumption) than that of summer gas.
LPG supplier network
The number of LPG pumps is constantly increasing.
Lists of existing LPG pumps may be found on Internet. 
LPG safety
A series of collision tests performed on this vehicle while running with LPG
have confirmed its high level of safety. The safety of the LPG system guarantees operation without risk. The follow-
ing safety measures have been adopted:
●
The LPG tank has a solenoid valve which closes automatically when the
engine is switched off (ignition off) or when running on petrol.
● A solenoid type main valve disconnects the supply of gas to the engine
compartment when the engine is switched off or running on petrol.
● A safety valve in the LPG tank with pipes to the outside prevents the gas
from entering the vehicle interior.
● All anchorage points and materials have been designed to ensure the
maximum possible levels of safety.
The condition of the LPG system should be checked regularly to guarantee
safe driving conditions ⇒ 
. These checks are included in the Maintenance
Programme.
WARNING
● If there is a smell of gas or a suspected leak, stop the vehicle immedi-
ately and switch off the ignition. Open the doors to ventilate the vehicle.
Do not carry on driving! Take the vehicle to a specialised workshop and
have the fault repaired.
● Immediately extinguish any cigarettes and remove from the vehicle
any objects which might produce a spark or cause a fire, and switch off
immediately if gas is smelt or a leak is detected.
● LPG tanks are subject to pressure and must be checked regularly. The
owner of the vehicle must check that these services are performed cor-
rectly.
● When parking the vehicle in a closed area (for example in a garage),
make sure that there is adequate ventilation, either natural or mechani-
cal, to neutralise the LPG in the event of a leak.
Note
For any fault in the LPG system, please refer to the SEAT web page, which
lists the workshops authorised to repair these faults. 

Checking and refilling levels
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. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the en-
gine 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 lever 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 coolant expansion tank when the en-
gine 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.WARNING (Continued)
● 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 clothing and long hair do not get trap-
ped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
– Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is ap-
plied. Danger of death.
● If work has to be carried out on the fuel system or on electrical com-
ponents, you must observe the following safety notes in addition to the
above warnings:
–Always disconnect the battery from the on-board network. The ve-
hicle 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 topping up service fluids, make sure not to mistake them. Using the
wrong fluids could cause serious malfunctions and engine damage! 

Checking and refilling levels
Brake fluid Checking the brake fluid level
The brake fluid is checked at the intervals given in the serv-
ice schedule.
Fig. 141 In the engine
compartment: Brake fluid
reservoir cover
– Read off the fluid level at the transparent brake fluid reservoir. It
should always be between the “MIN” and “MAX” marks.
The position of the brake fluid reservoir is shown in the corresponding en-
gine compartment illustration ⇒ page 259. The brake fluid reservoir has a
black and yellow cap.
The brake fluid level drops slightly when the vehicle is being used as the
brake pads are automatically adjusted as they wear.
However, if the level goes down noticeably in a short time, or drops below
the “MIN” mark, there may be a leak in the brake system. A display on the
instrument panel will warn you if the brake fluid level is too low ⇒ page 65.
WARNING
Before opening the bonnet to check the brake fluid level, read and ob-
serve the warnings ⇒ page 200.

Changing the brake fluid
The Maintenance Programme indicates the brake fluid
change intervals. We recommend that you have the brake fluid changed by a Technical Serv-
ice.
Before opening the bonnet, please read and follow the warnings ⇒ 
in
Safety instructions on working in the engine compartment on page 200 in
section “Safety notes for working in the engine compartment”.
Brake fluid absorbs moisture. In the course of time, it will absorb water from
the ambient air. If the water content in the brake fluid is too high, the brake
system could corrode. This also considerably reduces the boiling point of
the brake fluid. Heavy use of the brakes may then cause a vapour lock
which could impair the braking effect.
Be sure to always use the correct brake fluid. Only use brake fluid that ex-
pressly meets VW 501 14 standards.
You can buy VW 501 14 standard brake fluid in a SEAT dealership or SEAT
Official Service. If none is available, use only high quality brake fluid that
meets DIN ISO 4925 CLASS 4 standards, or USA Standards FMVSS 116 DOT
4.
Using any other kind of brake fluid or one that is not of a high quality may
affect operation of the brake system and reduce its effectiveness. Never use
a brake fluid if the container does not state that it complies with VW 501 14,
DIN ISO 4925 CLASS 4 standards, or USA standards FMVSS 116 DOT 4. 

224If and when
If you have a puncture on one of the front wheels when using snow chains,
fit the compact temporary spare wheel in place of one of the rear wheels.
You can then attach the snow chains to the wheel taken from the rear and
use this wheel to replace the punctured front wheel.
WARNING
● The tyre pressures must be checked and corrected as soon as possi-
ble after fitting the temporary spare wheel.
● Do not drive faster than 80 km/h (50 mph). Higher speeds can cause
an accident.
● Avoid heavy acceleration, hard braking and fast cornering. Risk of ac-
cident.
● Never use more than one temporary spare wheel at the same time,
risk of accident.
● No other type of tyre (normal summer or winter tyre) may be fitted on
the compact temporary spare wheel rim.

Tyre repair kit*
The tyre repair kit (for vehicles not including a temporary
spare wheel) is stored under the floor panel in the luggage
compartment. Your vehicle is equipped with the Tyre Mobility System “Tyre repair kit”.
The tyre repair kit consists of a container with sealing product to repair the
puncture and a compressor to generate the required tyre pressure. The kit
will reliably seal punctures up to a size of about 4 mm caused by the pene-
tration of a foreign body into the tyre.
Note
● Seek professional assistance if the repair of a tyre puncture is not possi-
ble with the sealing product. 
Wheel change Preparation work
What you must do before changing a wheel.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible. Choose a location that is as
level as possible.
– All vehicle occupants should leave the vehicle. They should
wait in a safe area (for instance behind the roadside crash barri-
er).
– Switch the engine off. Switch the hazard warning lights on and
place the warning triangles in position.
– Apply the handbrake firmly.
– Engage the first gear , or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle.
– Take the vehicle tools and the spare wheel out of the luggage
compartment. 
