•
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 152,
fig. 114 . 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. 115 .
For example:•
When driving with snow chains,
•
when driving in deep snow or on loose surfaces,

166Activation
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 connecter will be plugged into the vehicle.
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 acou stic 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 at tention 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.Caution
•
Please note that low obstacles detected by the system may no longer be
registered by the sensors as the car moves closer, so the system will not give
any further warning. Certain kinds of obstacles (such as wire fences, chains,
thin posts or trailer draw bars, high kerbs or painted railings etc) may not
always be detected by the system, so there is a risk of damaging the vehicle
in such cases.
•
In some cases, obstacles with uniform edges and bumps may not be
detected immediately by the system due to their geometry. Take special care
around this type of obstacle such as corners, rectangular objects, etc.., these
can cause damage to the vehicle.
•
Be especially carefully when manoeuvring into a corner between two
perpendicular walls. Survey the approach of the wall to the side of the vehicle
(using the mirrors)
•
The parking aid system does not repl ace use of the mirrors for manoeu-
vres.
•
Distant ultra-sonic sources (hammers, tyres, construction machinery,
other vehicles with PDC) may interfere with the operation of the system.
•
Periodic cleaning of the sensors, take care not to damage or scratch them.
When cleaning with high pressure washers or steam cleaners, the sensors
should be sprayed for only a very short period and from a distance of more
than 10 cm.WARNING (continued)

Tips and Maintenance
Te c h n i c a l D a t a
instance, city traffic, frequent short trips or hard driving with abrupt starts
and stops.
Wet roads; road salt
When the velocity is
over 80 km/h, and the windscreen wipers are on, the
brake system moves the pads towards the brake discs for a few seconds. This
occurs - without warning to the driver - in regular intervals and requires a
more rapid response from the brakes when driving on wet roads.
In certain conditions, such as in heavy rain, or after washing the car or driving
through water, the full braking effect can be delayed by moisture (or in winter
by ice) on the discs and brake pads. The brakes should be dried by pressing
the pedal to restore full braking effect.
The effectiveness of the brakes can also be temporarily reduced if the car is
driven for some distance without using the brakes when there is a lot of salt
on the road in winter. In this case, the layer of salt on the brake discs and pads
has to wear off before braking.
Corrosion
There may be a tendency for dirt to build up on the brake pads and corrosion
to form on the discs if the car is used infrequently, or if you only drive low
mileages without using the brakes very much.
If the brakes are not used frequently, or if corrosion has formed on the discs,
it is advisable to clean off the pads and discs by braking firmly a few times
from a moderately high speed ⇒.
Faults in the brake system
If the brake pedal travel should ever increase suddenly, this may mean that
one of the two brake circuits has failed. Drive immediately to the nearest qual-
ified workshop and have the fault rectified. On the way to the dealer, be
prepared to use more pressure on the brake pedal, and allow for longer stop-
ping distances. Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is too low.
The brake fluid level is monitored electronically.
Brake servo
The brake servo amplifies the pressure you apply to the brake pedal. The
brake servo works only when the engine is running.
WARNING
•
When applying the brakes to clean o
ff deposits on the pads and discs,
select a clear, dry road. Be sure no t to inconvenience or endanger other
road users. Risk of accident.
•
Ensure the vehicle does not move whil e in neutral, when the motor is
stopped. Failure to do so could result in an accident.Caution
•
Never let the brakes “drag” by leaving your foot on the pedal when you do
not really intend to brake. This overheats the brakes, resulting in longer stop-
ping distances and greater wear.
•
Before driving down a long, steep gradient, it is advisable to reduce speed
and change to a lower gear (or move the selector lever to a lower gear position
if your car has automatic transmission). This makes use of engine braking
and prolongs the service life of the brakes. If you still have to use the brakes,
it is better to brake firmly at intervals than to apply the brakes continuously.Note
•
If the brake servo is not functioning due to a malfunction, or if the vehicle
has to be towed, you will have to press the brake pedal considerably harder
to make up for the lack of servo assistance.

If you wish to equip the car with accessories such as a front spoiler or
wheel covers, it is important that the flow of air to the front wheels is not
obstructed, otherwise the brakes can overheat.
Braking effect and braking distance
The braking effect and braking distance are influenced by
driving situations and road conditions.The efficiency of the brakes depends directly on the brake pad wear. The rate
of wear of the brake pads depends to a great extent on the conditions under
which the vehicle is operated and the way the vehicle is driven. If you often
drive in town, drive short distances or have a sporty driving style, we recom-
mend that you have the thickness of your brake pads checked by an Approved
Service Centre more frequently than recommended in the Maintenance
Programme.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the car, the effect of the brakes is less-
ened as the brake discs are wet or even frozen (in winter): The brakes should
be dried by pressing the pedal to restore 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 move 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 199, “Modifications”.
•
If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Power steering (servotronic*)
The power steering assists the driver when turning the
steering wheel (with the engine running).The power steering assists the driver by reducing the force needed to turn the
steering wheel. In cars equipped with servotronic* power steering the degree
of power assistance is regulated electronically according to road speed.
If a fault should occur in the servotronic system the power steering* will still
operate. The degree of power assistance will, however, no longer adapt to

different speeds. If the electronic regu
lating system is not working properly,
this is most noticeable when turning the steering wheel at low speeds (for
instance when parking) – more effort will be required than usual. The fault
should be corrected by a qualified workshop as soon as possible.
The power steering does not work if the engine is off. In this case the steering
wheel is very hard to turn.
If the steering is held at its turning limit when the car is stationary, this will
place an excessive load on the power steering system, Turning the steering
wheel to its limits places a load on the system, which causes noise. It will also
reduce the idling s peed of the engine.
Caution
When the engine is running, do not tu rn the steering wheel to its limits for
more than 15 seconds. Otherwise, there is a risk of damaging the power
steering.
Note
•
If the power steering should fail at any time or the engine is switched off
(for instance when being towed), the car can still be steered. However, more
effort will be required to turn the steering wheel.
•
If the system is leaking or malfunctioning, please take the car to a quali-
fied workshop as soon as possible.
•
The power steering requires a special hydraulic fluid. The container is
located in the engine compartment (front left). The correct fluid level in the
reservoir is important for the power steering to function properly. The
hydraulic fluid level is checked at the Inspection Service.

– For engine oil changes, do not replenish with too much engine oil
⇒page 210, “Topping up engine oil ”.
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 255.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 72. 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! Fire hazard!•
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.
Diesel engine particulate filter*
The diesel engine particulate filter eliminates soot produced
by burning diesel.The diesel engine dust filter eliminates most of the soot from the exhaust gas
system. Under normal driving conditions, the filter cleans itself. If the driving
conditions do not allow the filter to clean itself (for example, multiple short
trips) the filter will be obstructed by dust and pollen and the indicator for the
diesel engine particulate filter indicator will light ⇒page 79.
WARNING
•
The diesel engine particulate filter may reach extremely high tempera-
tures; it should not enter into contact with flammable materials under-
neath the vehicle. Failure to comply could result in fire.Caution
Vehicles equipped with a diesel engine particulate filter must not be refueled
using biodiesel (RME), given that the fuel system may be damaged.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.
In vehicles with self-directing headlights, the rotation system must previ-
ously be disconnected. To do this please go to a specialist workshop.

Driving economically and with respect for the
environmentGeneral ObservationsFuel consumption, environmental pollut
ion and wear to the engine, brakes
and tyres depends in large part on your driving style. Fuel consumption may
be reduced from 10 to 15 % by driving defensively and economically. Below
we will give you some suggestions to "alleviate" some of the strain in the
environment and, at the same time, your wallet.
Anticipate the traffic situation well in advance
A vehicle uses most fuel when accelerating. When you anticipate the situa-
tion, you will have to brake less often and, thus, accelerate less. If it is
possible, let the vehicle roll with a gear engaged, for example, if you see a red
light ahead.
Change gear early to save energy
An effective way of saving fuel is to change up quickly through the gears.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.
Manual gearbox: Change from first to second gear as quickly as possible. We
recommend that, whenever possible, you change to a higher gear upon
reaching 2,000 rpms.
Automatic gearbox: Accelerate slowly and avoid the “kick-down” position. Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly at
higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at level
crossings or at traffic lights with a long red phase. The fuel saved after only
30 - 40 seconds is greater than the amount of fuel needed to restart the
engine.
The engine takes a very long time to
warm up when it is running at idling
speed. Mechanical wear and pollutan t emissions are also especially high
during this initial warm-up phase. It is therefore best to drive off immediately
after starting the engine. Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not waste fuel. A well-service d engine gives you the benefit of improved
fuel efficiency as well as maximum reliability and an enhanced resale value.
A maladjusted engine may mean an increase of 10 % over normal fuel
consumption.
Check the oil level every time you fill the tank. Oil consumption depends to a
great extent on the engine load and engine speed. It is quite normal that the
oil consumption of a new engine only reaches its lowest level after a certain
mileage. This means that the oil consumption can only be properly assessed
after about 5,000 km. Depending on your personal driving style, oil consump-
tion can be up to 0.5 litres per 1,000 km.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture .

Trailer towing
186Trailer towingInstructions to followYour 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.
Connector
Your vehicle is fitted with a 12-pin connector 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 SEAT dealer.
Trailer weight / draw bar loading
Never exceed the authorised towing limit. If you do not load the trailer up to
the maximum permitted tr ailer 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 spec ific 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 shoul d 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.

Fitting a towing bracket
•
Driving with a trailer implies additional work for the vehicle. Therefore,
before fitting a towing bracket, please contact an Authorised Service Centre
to check whether your cooling system needs modification.
•
Observe the legal requirements in yo ur country (e.g. the fitting of a sepa-
rate warning lamp).
•
Certain vehicle componen ts, e.g. the rear bumper must be removed and
reinstalled. The towing bracket securi ng bolts must be tightened using a
torque wrench, and an electrical sock et must be used to connect to the
vehicle's electrical system. This requires specialist knowledge and tools.
•
The figures in the illustration show the dimensions and attachment points
which must be observed if you are retrofitting a towing bracket.
WARNING
Towing brackets should be fitted by specialists.
•
If the towing bracket is incorrectly installed, there is serious danger of
an accident.
•
For your own safety, please observe the instructions provided by the
manufacturer of the towing bracket.Caution
•
If the electrical socket is incorrectly installed, this could cause damage to
the vehicle's electrical system.Note
For the sports model (FR, Cupra...), fitting of a trailer bracket is not recom-
mended due to the design of the bumpers.
