174Anti-lock brake system (ABS)The anti-lock brake system prevents the wheels locking during braking
⇒ page 172.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 78.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheel s 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 braked 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 vehi cle (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 199.The traction control system (TCS)The traction control system prevents the drive wheels from spinning when the
car is accelerating ⇒page 172.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
The rate of wear on the brake pads depends a great deal on how you drive and
the conditions in which the vehicle is operated. Negative factors are, for

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

Driving and the environment
184With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumptio n does not regularise until having
driven some four kilometres. This is the reas on why we recommend avoiding
short trips wherever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressures are just 1 bar too low, this can put the fuel consumption up by
as much as 5 %. Due to the greater rolling resistance, under-inflation also
increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all through the year: they will increase fuel consump-
tion by up to 10 %.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
Save electrical energy
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical equipment when you do not need them. Examples of equip-
ment that use a lot of electricity are: the fan at high speeds, the rear window
heating or the seat heaters*.
Logbook
A good way of keeping a check on fuel consumption is to take regular notes.
You will be able to note the variations (both positive and negative) and react
accordingly.

Cleaning and caring for your vehicle
198SEAT does everything possible to preserve the special qualities of leather, as
a natural product. Because of the natural properties of the specially selected
hides employed, the finished leather has a certain sensitivity to grease and
dirt, 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 left standing in the sun for long periods, the leather should be
protected against direct sunlight to pr event 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 qualified
workshop.
Cleaning seat belts
A dirty belt may stop the seat belt working properly.Keep the seat belts clean and check all seat belts regularly.
Cleaning seat belts
– Carefully pull the dirty seat belt right out and leave it out.
– Clean the dirty seat belts with a gentle soap solution.
– Allow the seat belt fabric to dry.
– Do not roll up the seat belt until it is dry.
If large stains form on the belts the belt will not retract correctly into the auto-
matic belt retractor.
WARNING
•
Do not use chemical cleaning agents on the seat belts, as this can
impair the strength of the webbing. Ensure that the belts do not come into
contact with corrosive fluids.
•
Check the condition of all seat belts at regular intervals. If you notice
that the belt webbing, fittings, retrac tor mechanism or buckle of any of the
belts is damaged, the belt must be replaced by a specialist workshop.
•
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 dr y completely before rolling them up.
Otherwise the belt retractors could become damaged.

charge. Never short the battery terminals. High-energy sparks can cause
injury.
•
A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated room
only.
•
Keep children away from acid and batteries.
•
Before working on the electrical system, you must switch off the
engine, the ignition and all consumers. The negative cable on the battery
must be disconnected. When a light bulb is changed, you need only switch
off the light.
•
Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alar m will otherwise be triggered.
•
When disconnecting the battery from the vehicle electrical system,
disconnect first the negative cable and then the positive cable.
•
Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never
reverse the polarity of the connections. This could cause an electrical fire.
•
Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery which
has frozen. A flat battery can freeze at temperatures around 0°C.
•
Ensure that the vent hose is always connected to the battery.
•
Never use a defective battery. This may be fatally explosive. Replace a
damaged battery immediately.Caution
•
Never disconnect the battery if the ignition is switched on or if the engine
is running. This could damage the electrical system or electronic compo-
nents.
•
Do not expose the battery to direct sunlight over a long period of time, as
the intense ultraviolet radiation can damage the battery housing.
•
If the vehicle is left standing in cold conditions for a long period, protect
the battery from frost. If it “freezes” it will be damaged.
Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries.– Open the bonnet and open the battery cover at the front ⇒ in
“Safety instructions on working in the engine compartment” on
page 204 ⇒ in “Warnings on handling the battery” on
page 218.
– Check the colour display in the "magic eye" on the top of the battery.
– If there are air bubbles in the window, tap the window gently until they disperse.The position of the battery is show n in the corresponding engine compart-
ment diagram ⇒page 266.
The round window (“magic eye”) on the top of the battery changes colour,
depending on the charge level and electrolyte level of the battery.
If the colour in the window is colourless or bright yellow, the electrolyte level
of the battery is too low. Have the battery checked by a qualified workshop.
The colours green and black are used by the workshops for diagnostic
purposes.

Te c h n i c a l D a t a
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km and if the circumstances are favourable (for
example, low load), even more.
The damaged tyre should be changed as soon as possible. The rim should be
checked in a specialist workshop to detect possible damage and replace it if
necessary. We recommend you contact Technical Service. If more than one
tyre is being used under emergency conditions, this reduces the distance
which can be travelled.
Starting driving in emergency conditions
At the moment the loss of tyre pressure is indicated on the instrument panel,
at least one of the tyres is driving in emergency mode
⇒.
End of emergency operation
Do not drive on if:
•
smoke is coming from one of the tyres,
•
there is a smell of rubber,
•
the vehicle vibrates,
•
there is a rattling noise.
When is it no longer possible to continue driving even using anti-puncture
tyres?
•
If the Electronic Stabilisation Pro gram (ESP) is out of operation.
•
If the tyre pressure monitoring system is out of operation.
•
If one of the tyres has been severely damaged in an accident, etc. If a tyre
has been badly damaged there is a risk that parts of the tread can be thrown
off and cause damage to the fuel lines, brake pipes or fuel filler.
•
It is also advisable to stop driving if severe vibrations occur, or if the wheel
starts overheating and gives off smoke.
WARNING
When driving in emergency conditions, the driving quality of the vehicle is
considerably impaired.•
The maximum permitted speed of 80 km/h is subject to road and
weather conditions. Please observe legal requirements when doing so.
•
Avoid sharp turns and rapid manoeuvres, and brake earlier than usual.
•
Avoid driving over obstacles (for example kerbs) or potholes.
•
If one or more tyres is being driven in emergency conditions, the driving
quality of the vehicle is impaired and there is a risk of accident.Note
•
The anti-puncture tyres do not “deflate” on losing pressure because they
are supported on the reinforced sides. Therefore defects in the tyre can not be
detected with a visual inspection.
•
Snow chains must not be used on front tyres used in emergency
conditions.
New tyres and wheels
New tyres and wheels have to be run-in.The tyres and wheel rims are an essential part of the vehicle's design. The
tyres and rims approved by SEAT are specially matched to the characteristics
of the vehicle and make a major contribution to good road holding and safe
handling ⇒.
Tyres should be replaced at least in pair s and not individually (i.e. both front
tyres or both rear tyres together). A knowledge of tyre designations makes it
