•
Adjust the driver seat or steering wheel so that there is a distance of at
least 25 cm between the steering wheel and your breast bone ⇒page 146,
fig. 110 . If you fail to observe the minimum distance, the airbag will not
protect you. Risk of fatal injury.
•
If your physical constitution prevents you from maintaining the
minimum distance of 25 cm, contact an Authorised Service Centre. The
Authorised Service Centre will help you decide if special specific modifica-
tions are necessary.
•
If you adjust the steering wheel so th at it points towards your face, the
driver airbag will not protect you prop erly in the event of an accident. Make
sure that the steering wheel points towards your chest.
•
When driving, always hold the steering wheel with both hands on the
outside of the ring at the 9 o'clock and 3 o'clock positions. Never hold the
steering wheel at the 12 o'clock position, or in any other manner (e.g. in
the centre of the steering wheel, or on the inside of the rim). In such cases,
you could receive severe injuries to the arms, hands and head.
SafetyElectronic stabilisation programme (ESP)*
ESP helps make driving safer in certain situations.The Electronic Stabilisation Program (ESP ) contains the electronic differential
lock (EDL) and the traction control system (TCS). The ESP function works in
conjunction with the ABS. Both warning la mps will light up if the ESP or ABS
systems are faulty.
The ESP is started automatically when the engine is started.
In specific circumstances where you requ ire less traction, you can switch off
the ESP by pressing button ⇒fig. 111 .
For example:•
When driving with snow chains,
•
when driving in deep snow or on loose surfaces,

Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.
Acoustic parking aid system*Rear parking aid
The parking aid system will use an acoustic signal to warn of
the approach of any object towards the rear of the vehicle.Description
The acoustic parking aid system will measure the distance between the rear
of the vehicle and any possible obstacle using four ultrasonic sensors located
on the rear bumper. The measuring range of the sensors starts at approxi-
mately and depending on the nature of the obstacle at a distance of:•
side of the rear bumper: 0.8 m
•
centre of the rear bumper: 1.3 m
Activation
The system is activated by engagement of the reverse gear. A brief acoustic
signal confirms the activation and correct function of the system.
Reversing
The distance warning will begin as soon as an obstacle is detected by the
system. The frequency of the bleeps emitted by the system will increase
rapidly as the vehicle approaches the obstacle.
Within a short distance of about 25 cm, a continuous signal sounds (stop
signal). The driver should not reverse any further. Trailer towing
For vehicles fitted with a tow bar by the manufacturer, the parking aid system
will not be activated by the engagement of the reverse gear when pulling a
trailer, as the trailer's electric conne
cter will be plugged into the vehicle.
To avoid system malfunctions, when not driving with a trailer, remove the
trailer hitch.
Possible faults
If a continuous bleep sounds for some seconds when the reverse gear is
engaged, this indicates that there is a fault in the parking aid system.
If the fault continues until the ignition is turned off, the acoustic signal
warning of the fault will not be emitted every time the system is reactivated
(by engaging the reverse gear). Thus, the system ready indication will not
sound either. Have the fault repaired by an Authorised Service Centre as soon
as possible.
If there is no ready signal or no acoustic warning signal then the parking aid
loudspeaker is faulty and may not warn of obstacles.
To ensure that the system works properly, the sensors must be kept clean and
free of ice and snow.
WARNING
•
The sensors have blind spots in which obstacles may not be detected.
•
Always look out for small children and animals because the system will
not always detect them. Always pay attention when reversing to avoid acci-
dents.
•
The parking aid is not a replacement for driver awareness. The driver
must take full responsibility for parking and other manoeuvres.

Driving and the environment
170Authorised Service Centre more frequently than recommended in the Service
Schedule.
If you drive with wet brakes, for example after driving through water, after
heavy rainfall or after washing the car, the braking effect will be reduced as
the brake discs will be wet, or possibly frozen (in winter): the brakes must be
“dried” through careful braking.
The brake fluid must be changed every two years at the latest. Heavy use of
the brakes may cause a vapour lock if the brake fluid is left in the system for
too long. This prevents the brakes developing their full braking effect.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.•
New brake pads must be run in and do not have the correct friction
during the first 200 km. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also
applies when new brake pads are fitted.
•
If brakes are wet or frozen, or if you are driving on roads which have
been gritted with salt, braking power may set in later than normal.
•
On steep descents if the brakes are excessively used they will over
heat. Before driving down a long steep gradient, it is advisable to reduce
speed and change to a lower gear (or mo ve the selector lever to a lower gear
if your vehicle has automatic transmission). This makes use of engine
braking and relieves the brakes.
•
Never let the brakes “rub” by applying light pressure. Continuous
braking will cause the brakes to overheat and will increase the braking
distance. Apply and then release the brakes alternately.
•
Never let the vehicle coast with the engine switched off. The braking
distance is increased considerably as the brake servo does not function.
•
Very heavy use of the brakes may cause a vapour lock if the brake fluid
is left in the system for too long. This impairs the braking effect.
•
Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Observe the relevant instructions
before purchasing accessories ⇒page 186, “Modifications”.
•
If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Catalytic converter*To conserve the useful life of the catalytic converter
– Always use unleaded petrol.
– Do not run the fuel tank dry.
– For engine oil changes, do not replenish with too much engine oil ⇒page 199, “Topping up engine oil ”.
– Never tow the vehicle to start it, use jump leads if necessary ⇒page 240.If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest qualified workshop. In general, the exhaust warning lamp will light
up when any of the described symptoms occur ⇒page 71. If this happens,
unburnt fuel can enter the exhaust system and escape into the environment.
The catalytic converter can also be damaged by overheating.

WARNING
The catalytic converter reaches very high temperatures! Risk of fire.•
Never park where the catalytic converter could come into contact with
dry grass or inflammable materials under the vehicle.
•
Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust
system. These materials could catch fire when the vehicle is driven.Caution
Never fully drain the fuel tank, in this case, the irregularity of the fuel supply
may cause ignition problems. This allow s unburnt fuel to enter the exhaust
system, which could cause overheating and damage the catalytic converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust unde r some conditions. This depends on
the sulphur content of the fuel used. Quite often the problem can be reme-
died by changing to another brand of fuel.Driving abroadNotesFor driving abroad, the following must be taken into consideration:
•
For vehicles fitted with a catalytic converter ensure that unleaded petrol is
available for the journey. See the chap ter “Refuelling”. Automobile organisa-
tions will have information about service station networks selling unleaded
fuel.
•
In some countries it is possible that a vehicle model is sold under condi-
tions where some spare parts are not available or that the Authorised Service
Centres may only carr y out limited repairs.
SEAT importers and distributors will gladly provide information about the
technical preparation of your vehicle in addition to necessary maintenance
and repair possibilities.
Adhesive strips for headlightsIf you have to drive a right-hand drive vehicle in a left-hand drive country, or
vice versa, the asymmetric dipped beam headlights will dazzle oncoming
traffic.
To prevent dazzling, you must apply stickers to certain parts of the headlight
lenses. Further information is available from your Authorised Service
Centre.

Trailer towingWhat do you need to bear in mind when towing a trailer?Your vehicle may be used to tow a trailer when fitted with the correct equip-
ment.
If the car is supplied with a
factory-fitted towing bracket it will already have
the necessary technical modifications and meet the statutory requirements
for towing a trailer. For the after-market fitting of a trailer towing bracket see
⇒ page 188.
Connectors
Your vehicle is fitted with a 12-pin co nnector for the electrical connection
between the trailer and the vehicle.
If the trailer has a 7-pin plug you will need to use an adapter cable. This is
available from any Technical Service.
Trailer weight / draw bar loading
Never exceed the authorised towing limit. 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
1,000 m above sea level. With increasing altitude the engine power and
therefore 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 combination must be reduced by 10% for
every further 1,000 m (or part thereof).
The gross combination weight is the
actual weight of the laden vehicle plus the actual weight of the laden trailer.
Where possible, operate the trailer with the maximum permitted draw bar
weight on the ball joint of the towing bracket, but do not exceed the specified
limit.
The figures for trailer weights and draw bar weights that are given on the
data 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 ⇒Section
“Technical data”.
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.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the sticker
on the inside of the fuel tank flap. Set the tyre pressure of the trailer tyres in
accordance with the trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. Both exterior mirrors should be mounted on hinged extension
brackets. Adjust the mirrors to give sufficient vision to the rear.
WARNING
Never transport people in a trailer. This could result in fatal accidents.

Note•
Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the
vehicle is used frequently for towing a trailer.
•
Find out whether special regulations apply to towing a trailer in your
country.
Ball coupling of towing bracket*Depending on the model version, the spherical head on the trailer hook may
be found in the tool box.
The ball coupling is provided with in structions on fitting and removing the
ball coupling of the towing bracket.
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 prevent the jerking that can be
caused by the trailer wheels locking. Sele ct 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
When climbing long hills in hot weather with the engine running fast in a low
gear, you should monitor the coolant temperature gauge ⇒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.

Tips and Maintenance
Te c h n i c a l D a t a
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 styl e 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.
Think ahead when drivingA vehicle uses most fuel when accelera ting. If you think ahead when driving,
you will need to brake less and thus accelerate less. Wherever possible, let
the vehicle roll slowly to a stop, for instance when you can see that the next
traffic lights are red.
Regular servicingBy taking your car to an Authorised Se rvice Centre for regular servicing you
can establish a basis for good fuel economy before you start driving. A well-
serviced engine gives you the benefit of improved fuel efficiency as well as
maximum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Check the oil level every time you fill the tank ⇒page 198. Oil consumption
depends to a great extent on the engine load and engine speed. Depending
on your personal driving style, oil consumption can be up to 1 litre per 1,000
km.Avoid short journeysThe engine and catalytic converter need to reach their proper working
temperature in order to minimise fuel consumption and emissions.

Cleaning and caring for your vehicleGeneral notesRegular washing and care help maintain the value of your
vehicle.Regular care
Regular and expert care helps to maintain the value of the vehicle. This may
also be one of the requirements for acknowledging warranty claims in the
event of corrosion or paint defects.
The best way to protect the car against environmental contaminants is to
wash and wax it frequently. The longer substances such as insects, bird drop-
pings, resinous tree sap, road dirt, industrial deposits, tar, soot or road salt
and other aggressive materials remain on the vehicle, the more damage they
do to the paintwork. High temperatur es (for instance in strong sunlight)
further intensify the corrosive effect.
After the period when salt is put on the roads it is important to have the
underside of the vehicle washed thoroughly.
Car care products
Car care products are available from your Authorised Service Centre. Keep the
product instructions until you have used up the product.
WARNING
•
Car care products can be toxic. For this, they must always be kept
closed in their original container. Keep out of children's reach. Failure to
comply could result in poisoning.
•
Always read and observe the instructions and warnings on the package
before using car care products. Improper use could damage your health or your vehicle. The use of certain products may produce noxious vapours;
these should be used in well ventilated areas.
•
Never use fuel, turpentine, engine oil, nail varnish remover or other
volatile fluids. These are toxic and highly flammable. There is a fire / explo-
sion risk.
•
Before you wash your vehicle, or carry out any maintenance, switch off
the engine, apply the handbrake firmly and remove the key from the igni-
tion.Caution
Never attempt to remove dirt, mud or dust if the surface of the vehicle is dry.
Never use a dry cloth or sponge for clea ning purposes. This could damage the
paintwork or glass on your vehicle. Soak dirt, mud or dust with plenty of
water.
For the sake of the environment
•
When purchasing car care products, try to select ones which are not
harmful to the environment.
•
Left over car care products should not be disposed of with ordinary house-
hold waste. Observe the disposal information on the package.WARNING (continued)

luggage compartment, or bonnet. This could cause them to freeze. Otherwise
there is a risk of malfunction.
For the sake of the environment
In the interests of environmental protection, the car should be washed only
in specially provided wash bays. This prevents toxic, oil-laden waste water
entering the sewerage system. In some districts, washing vehicles anywhere
else may be prohibited.
Note
Do not wash the vehicle in direct sunlight.Washing the car with a high pressure cleaner
Be particularly careful when using a high pressure cleaner!– Always observe the instructions for the high-pressure cleaner,
particularly those concerning the pressure and the spraying
distance .
– Increase the spraying distance for soft materials and painted bumpers.
– Do not use a high pressure cleaner to remove ice or snow from windows ⇒page 180.
– Never use concentrated jet nozzl es or so-called “dirt blasters”
⇒ .
– If possible, avoid sudden braking directly after washing the vehicle. You must “dry” the brakes by applying the brakes care-
fully several times ⇒page 169.
WARNING
•
Never wash tyres with a concentrated jet or cylindrical jet (“rotating
nozzle”). Even at large spraying distances and short cleaning times, visible
and invisible damage can occur to the tyres. This may be an accident risk.
•
Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident.Caution
•
Do not use water hotter than 60
°C. This could damage the car.
•
To avoid damage to the vehicle, maintain a sufficient distance from sensi-
tive materials for example: flexible hoses, plastic, sound proofing, etc. This is
especially important for bumpers painte d in the same colour as the vehicle.
The closer the nozzle is to the surface, the greater the wear on the material.
Waxing the car
Regular waxing protects the paintwork.You need to apply wax to your car if water does not form small drops and run
off the paintwork when it is clean.
Good quality hard wax is available from your Authorised Service Centre.
A good coat of wax helps to protects the paintwork from environmental
contaminants ⇒page 177. It is also effective in protecting against minor
scratches.
Even if a wax solution is used regularly in the car wash, it is advisable to
protect the paint with a coat of hard wax at least twice a year.

180Polishing the paintwork
Polishing brings back gloss to the paintwork.Polishing is only necessary if the paint has lost its shine, and the gloss cannot
be brought back by applying wax. Poli sh can be obtained from your Author-
ised Service Centre.
The car must be waxed after polishing if the polish used does not contain wax
compounds to seal the paint ⇒page 179, “Waxing the car”.
Caution
To prevent damage to the paintwork:•
Do not use polishes and hard wax on painted parts with a matt finish or
on plastic parts.
•
Do not polish your vehicle in a sandy or dusty environment.
Caring for plastic parts
Solvents will damage plastic parts.If normal washing fails to clean plastic parts, clean them with special solvent-
free plastic cleaning and care products.
Caution
•
The use of liquid air conditioners directly over the air vents of the vehicle
may damage the plastic parts if the liquid is accidentally spilled.
•
Cleaning products which contain solvents will damage the material.
Cleaning windows and exterior mirrorsCleaning the windows
– Moisten the windows with commercially available, alcohol based glass cleaner.
– Dry the windows with a clean chamois leather or a lint-free cloth.
Removing snow
– Use a small brush to remove snow from the windows and mirrors.
Removing ice
–Use a de-icer spray.Use a clean cloth or chamois leather to dry the windows. Chamois leathers
which have been used on painted surfaces are not suitable for use on
windows. They will be soiled with wax deposits which would smear the
windows.
If possible use a de-icing spray to remove ice. If you use an ice scraper, push
it in one direction only. Do not move it to and fro.
Use window cleaner or a silicone remover to clean off rubber, oil, grease and
silicone deposits.
Wax deposits have to be removed with a special cleaner which is available
from your Authorised Service Centre. Wax deposits on the windscreen could
cause the wiper blades to judder. A window cleanser specifically for removing
wax will stop the blades juddering if added to the windscreen washer fluid.
Grease removing cleansers will not remove wax deposits.
Caution
•
Never use warm or hot water to remove snow and ice from windows and
mirrors. This could cause the glass to crack!
