Tips and MaintenanceIntelligent technologyBrakesBrake servoThe brake servo amplifies the pressure you apply to the brake pedal. It works
only when the engine is running .
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.
WARNING
The braking distance can also be affected by external factors.•
Never let the vehicle coast with the engine switched off. Failure to do so
could result in an accident. The braking distance is increased considerably
as the brake servo does not function.
•
If the brake servo is not functioning, for example if the vehicle is being
towed, you will have to press the brake pedal considerably harder than
normal.
Brake assist system (BAS)*In an emergency, most drivers brake in time, but not with maximum force.
This results in unnecessarily long braking distances. The brake assist system intervenes here, if you press the brake pedal very
quickly, the brake assist system registers an emergency situation. It then very
quickly builds up the full brake pressure so that the ABS can be activated
more quickly and efficiently, thus reducing the braking distance.
Do not reduce the pressure on the br
ake pedal. The brake assist system
switches off automatically as soon as you release the brake.
WARNING
•
The risk of accident is higher if yo u drive too fast, if you do not keep
your distance to the vehicle in front, and when the road surface is slippery
or wet. The increased accident risk cannot be reduced by the brake assist
system.
•
The brake assist system cannot defy the laws of physics. Slippery and
wet roads are dangerous even with the brake assist system! Therefore, it is
essential that you adjust your speed to suit the road and traffic conditions.
Do not let the extra safety features tempt you into taking any risks when
driving.

The TCS should be switched on again afterwards as soon as possible.
WARNING
•
It must be remembered that TCS cann
ot defy the laws of physics. This
should be kept in mind, particular ly 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 TCS tempt you
into taking any risks when driving, this can cause accidents.Caution
•
In order to ensure that TCS function 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 wh eels and tyres) could affect the effi-
ciency of the ABS and TCS.
Electronic stabilisation program (ESP)*General notes
The electronic stabilisation program increases the vehicle's
stability on the road.The electronic stabilisation program helps to reduce the danger of skidding.
The electronic stabilisation programme (ESP) consists of ABS, EDL and TCS. Electronic Stabilising Program (ESP)*
ESP reduces the danger of skidding by braking the wheels individually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehi
cle. If the desired course is not being
maintained (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.
WARNING
•
It must be remembered that ESP cann ot 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

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.Note

Tips and Maintenance
Te c h n i c a l D a t a
Driving 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 faster than three quarters of top 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 fric tion 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, the life of the engine will be increased and its oil
consumption reduced.
Running in tyres and brake pads
New tyres should be run-in carefully for the first 500 km. New
brake pads should be run-in carefully for the first 200 km.During the first 200 km, you can compensate for the reduced braking effect
by applying more pressure to the brake pedal. If you need to make an emer-
gency stop, the braking distance will be longer with new brake pads than with
brake pads which have been run-in.
WARNING
•
New tyres do not give maximum grip to start with, and require running-
in. This may be an accident risk. Drive particularly carefully in the first 500
km.
•
New brake pads must be “run in” and do not have the correct friction
properties during the first 200 km. However, the reduced braking capacity
may be compensated by pressing on the brake pedal a little harder.
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

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.

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.
