Intelligent technology
184maintained (for instance, if the car is starting to skid), then the ESP compen-
sates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle tends to oversteer, the system will act on the front
wheel on the outside of the turn.
Steering manoeuvre recommendations
This is a complementary safety function included in the ESP This function aids
the driver to better stabilize the vehicle in a critical situation. For example, in
case of sudden braking surface with varied adherence, the vehicle will tend
to destabilize its trajectory to the right to or to the left. In this case the ESP
recognizes the situation and helps the driver with a counter steering
manoeuvre from the power steering.
This function simply provides the driver with a recommended manoeuvre in
critical situations.
The vehicle doesn't steer itself with this function, the driver has full control of
the vehicle at all times.
WARNING
•It must be remembered that ESP cannot defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.•Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by ESP tempt you
into taking any risks when driving, this can cause accidents.Caution
•In order to ensure that ESP functions correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
•Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the ABS, EDL, ESP and TCS.Anti-lock brake system (ABS)The anti-lock brake system prevents the wheels locking during braking
⇒ page 182.Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.EDL helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
The system will control the revolutions of the drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 79.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheels of approximately 100 rpm caused by
a slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the other
driven wheel via the differential.
To prevent the disc brake of the braking wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. The vehicle will continue to
function normally without EDL. For this reason, the driver is not informed that
the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled down.

WARNING
•When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may start to
spin. This could impair the vehicle's stability.•Always adapt your driving style to suit road conditions and the traffic
situation. Do not let the extra safety afforded by EDL tempt you into taking
any risks when driving, this can cause accidents.Caution
Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the EDL ⇒page 206.The traction control system (TCS)The traction control system prevents the drive wheels from spinning when the
car is accelerating ⇒page 182.Four-wheel drive*
On four-wheel drive models, the engine power is distributed
to all four wheelsGeneral notes
The four-wheel-drive system operates completely automatically. The propul-
sion force is distributed among the four wheels and adapted to the driving
style and the road conditions. The four-wheel drive is specially designed to complement the superior engine
power. This combination gives the car exceptional handling and performance
capabilities – both on normal roads and in more difficult conditions, such as
snow and ice.
Winter tyres
Thanks to its four-wheel drive, your car will have plenty of traction in winter
conditions, even with the standard tyres. Nevertheless, we still recommend
that winter tyres or all-season tyres should be fitted on all four wheels when
winter road conditions are expected, mainly because this will give a better
braking response.
Snow chains
On roads where snow chains are mandatory, this also applies to cars with
four-wheel drive.
Changing tyres
On vehicles with four-wheel drive, all four tyres must have the same rolling
circumference
⇒page 237.
WARNING
•Even with four-wheel drive, you should always adjust your speed to suit
the conditions. Do not let the extra safety features tempt you into taking
any risks when driving. Failure to do so could result in an accident.•The braking capability of your vehicle is limited by the tyres' grip.
Vehicle behaviour is no different from a vehicle without four-wheel drive.
So do not be tempted to drive too fast on icy or slippery roads just because
the car still has good acceleration in these conditions. Failure to do so
could result in an accident.•On wet roads bear in mind that the front wheels may start to “aqua-
plane” and lose contact with the road if the car is driven too fast. If this
should happen, there will be no sudden increase in engine speed when
“aquaplaning” begins to warn the driver, as with a front-wheel drive car.
For this reason and for that mentioned above, always choose a driving

186speed suitable for the road conditions. Failure to do so could result in an
accident.Brakes
What factors can have a negative effect on the brakes?New brake pads
New brake pads do not provide optimal performance during the first 400 km
they must be “run in”. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. Avoid over-
loading the brakes during run-in.
Wear
T h e r a t e o f we a r o n t h e brake pads depends a great deal on how you drive and
the conditions in which the vehicle is operated. Negative factors are, for
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 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 - at 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 rust has formed on the disks, it is
advisable to clean off the pads and disks 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 off deposits on the pads and discs,
select a clear, dry road. Be sure not to inconvenience or endanger other
road users. Risk of accident.•Ensure the vehicle does not move while in neutral, when the motor is
stopped. Failure to do so could result in an accident.

Driving and the environment
188Driving and the environmentRunning-inRunning in a new engine
The engine needs to be run-in over the first 1,500 km.Up to 1,000 kilometres
– Do not drive at speeds of more than 2/3 the maximum speed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1000 to 1500 km
–Speeds can be gradually increased to the maximum road speed
or maximum permissible engine speed (rpm).During its first few hours of running, the internal friction in the engine is
greater than later on, when all the moving parts have bedded in.
For the sake of the environment
If the engine is run in gently, its life will be increased and its oil consumption,
reduced.
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 traffic, drive short distances or have a sporty driving style, we
recommend that you have the thickness of your brake pads checked by an
Authorised Service Centre more frequently than recommended in the Service
Schedule.
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 400 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 slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed and
change down into 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 “slip” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.•Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.•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 206, “Technical modifications”.•If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Exhaust gas purification systemCatalytic converter*To conserve the useful life of the catalytic converter
– Always use unleaded petrol.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not top the reservoir up ⇒page 220,
“Topping up engine oil ”. – Never tow the vehicle to start it, use jump leads if necessary
⇒page 263.
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 75. 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 being driven.Caution
Never fully drain the fuel tank because the irregularity of the fuel supply may
cause ignition problems. This allows 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 under some conditions. This depends on
the sulphur content of the fuel used. Quite often the problem can be solved
by changing to another fuel brand.

190Diesel 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 up. See section on
Warning Lights.
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
•The vehicle is not designed for refuelling with mixtures of FAME fuel
(biodiesel) over 7% in accordance with DIN 51628. The diesel particle filter is
damaged when this mixture percentage is exceeded.
Economical and environmentally friendly
drivingEconomical and environmentally friendly drivingFuel consumption, environmental pollution and wear to the engine, brakes
and tyres depends in large part on your driving style. By adopting an econom-
ical driving style and anticipating the traffic situation ahead, you can easily
reduce fuel consumption by 10-15%. Next, we provide you with some tips in
order to help reduce contamination and,at the same time, save money.
As you drive try to anticipate the traffic situation
A vehicle uses most fuel when accelerating. When you anticipate the situa-
tion, you 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. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero
(disconnection due to inertia).
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 rpm.
Automatic gearbox: Accelerate in moderation and avoid the “kick-down” (full
throttle) position.

Trailer towing193
Safety First
Controls and equipment
Practical tips
Technical Data
Trailer 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 195.
Connectors
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 in 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 trailer weight, you can then climb correspondingly
steeper slopes.
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.
When 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.

Trailer towing
194•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 instructions 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 re moved if a trailer is not being towed
and it obscures the number plate.Driving tipsDriving 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
an 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 due course. 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. Select a low gear in due course before
going down a steep downhill. This enables you to use the engine braking to
slow down the vehicle.
Reheating
At very high temperatures and during prolonged ascents, driving in a low gear
and high engine speed, always monitor the temperature indicator for the
coolant ⇒page 53.
Electronic Stabilisation Program*
The ESP* system makes it easier to stabilise the trailer in case it skids or
swings.

Trailer towing
196If a towing bracket is to be fitted after the vehicle is purchased, this must be
completed according to the instructions of the towing bracket manufacturer.
The attachment points for the towing bracket are on the lower part of the
vehicle.
The distance between the centre of the ball coupling and the ground should
never be lower than the indicated value, even with a fully loaded vehicle and
including the maximum resting weight.
Elevation values for securing the towing bracket:
65 mm (minimum)
350 mm to 420 mm (fully laden vehicle)
357 mm
569 mm
875 mm
1,040 mm
Fitting a towing bracket•Driving with a trailer involves an extra effort for the vehicle. Therefore,
before fitting a towing bracket, please contact an Authorised Service Centre
to check whether your cooling system needs modification.•Submit to the legal requirements in your country (e.g. the fitting of a sepa-
rate warning lamp).•Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securing bolts must be tightened using a
torque wrench, and an electrical socket must be connected to the vehicle's
electrical system. The above-mentioned require specialized knowledge and
tools.•Figures in the illustration show the elevation value and the attachment
points which must be considered 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
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.

Cleaning and caring for your vehicleGeneral notesRegular washing and care help maintain the value of your
vehicle.Yo u r v e h i c l e m a i n te n a n ce
Regular care and washing help to maintain the value of the vehicle. This may
also be one of the requirements for acknowledging warranty claims in the
event of bodywork 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 remains,
bird droppings, 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 temperatures (for instance in strong
sunlight) further intensify the corrosive effect.
After winter, a period when salt is put on the roads, it is impor tant to have the
underside of the vehicle washed thoroughly.
Products for vehicle maintenance
Car care products are available in your Authorised Service Centre. Keep the
product instructions until you have used them up.
WARNING
•Car care products can be toxic. For this, they must always be kept
closed in their original container. Keep them out of the reach of children.
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;
they 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. Risk of fire and explo-
sion.•Before washing your vehicle, or carrying out any maintenance, switch
the engine off, apply your handbrake firmly and remove the key from the
ignition.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 cleaning purposes. This could damage the
paintwork or the windows of your vehicle. Soak dirt, mud or dust with plenty
of water.
For the sake of the environment
•When purchasing products for your vehicle maintenance, select the ones
which are not harmful to the environment.•The leftovers of the car care products should not be disposed of with ordi-
nary household waste. Observe the disposal information on the package.WARNING (continued)
