Brakes
Brake servo
The brake servo supplements the pressure you exert on the brake pedal. It
works only when the engine is running.
If the brake servo does not operate, for example, when the vehicle is being
towed or due to a fault in the system, the brake pedal must be depressed
harder.
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 out of action, for example if the car is being towed,
you will have to press the brake pedal considerably harder than normal.
Brake pads wear display I
If this light comes on, check the brake pads immediately.
At the same time, a text message or the necessary operations may appear on
the instrument panel .
WARNING
If the warning lamp lights up I or the corresponding message appears on
the instrument panel, immediately have the brake pads checked and
replaced, if necessary, at a specialised workshop.
Brake warning lamp H
If the warning lamp comes on, this may be caused by the
following reasons:
•With the handbrake on the warning light comes on H on the instrument
panel. If you are travelling at over 6 km/h with the hand brake on, a text
message or the required operations may appear on the instrument panel. In
addition a warning signal is heard.
•In the event of insufficient brake fluid the warning lamp lights up H on
the instrument panel. At the same time, a text message or the necessary oper-
ations may appear on the instrument panel . Stop the vehicle immediately
and check the level of the brake fluid Ÿpage 221
•In the event of a fault in the brake system the warning lamp lights up H
on the instrument panel and three buzzes are emitted. At the same time, a
text message or the necessary operations may appear on the instrument
panel . Stop the vehicle and do not drive on. You should obtain professional
assistance. This warning lamp
H can light up together with the anti-locking
brake system warning lamp JŸ.

WARNING
Special care must be taken when working on the engine or on components
in the engine compartment.
•It is important that you read and observe the corresponding warnings
before working in the engine compartment Ÿpage 209.
•If the brake warning symbol does not go out, or if it lights up when
driving, the brake fluid level in the reservoir is too low or there is a fault in
the brake system. Risk of accident. Stop the vehicle and do not drive on.
You should obtain professional assistance.
•If the brake warning lamp H lights up together with the ABS warning
lamp J, the control function of the ABS could be out of action. This could
cause the rear wheels to lock quickly when you brake. This could cause the
rear to break away. Risk of skidding. Drive carefully to the nearest qualified
workshop and have the fault corrected.
Brake assist system (BAS)
The brake servo (BAS) works only when the engine is running.
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 brake pedal. The brake assist system
switches off automatically as soon as you release the brake.
WARNING
Try to always adapt the speed of the vehicle to weather, road and traffic
conditions. Do not let the extra safety afforded by the system tempt you
into taking any risks when driving. Risk of accident.
•The risk of accident is higher if you drive too fast, if you do not keep
your distance from the car 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 motion. Slippery and
wet roads are dangerous even with the brake assist system!
•Modifications to the vehicle or work carried out incorrectly (e. g. to the
engine, the brake system, running gear or any components affecting the
wheels and tyres) could affect the efficiency of the ABS, EDL, ESP and TCS
and lessen their efficiency.
Anti-locking brake system (ABS)
The anti-lock brake system prevents the wheels locking
during braking.
The anti-lock brake system (ABS) is an important part of the car's active safety
system.
How the ABS works
If one of the wheels is turning too slowly in relation to the road speed, and is
close to locking, the system will reduce the pressure for this wheel. The driver
is made aware of this control process by a pulsating of the brake pedal and
audible noise. This is a deliberate warning to the driver that one or more of
the wheels is tending to lock and the ABS control function has intervened. In
this situation it is important to keep the brake pedal fully depressed so the
ABS can regulate the brake application. Do not “pump” the brake pedal.

Intelligent technology 182
•If the brake warning lamp H should light up together with the ABS
warning lamp J, stop the vehicle immediately and check the brake fluid
level in the reservoir Ÿpage 221. If the fluid level has dropped below the
“MIN” mark you must not drive on. Risk of accident. You should obtain
professional assistance.
•If the brake fluid level is correct, the fault in the brake system may have
been caused by a failure of the ABS control function. This could cause the
rear wheels to lock quickly when you brake. This could cause the tail of the
vehicle to skid sideways. Drive carefully to the nearest qualified workshop
and have the fault corrected.
Electronic differential lock (EDL)
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.
The electronic differential lock (EDL) only works when the engine is running.
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.
It uses the ABS sensors to monitor the speed of the driven wheels.
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 braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. The car remains operational
and will behave in the same way as a car 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
Try to always adapt the speed of the vehicle to weather, road and traffic
conditions. Do not let the extra safety afforded by the system tempt you
into taking any risks when driving. Risk of accident.
•When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may other-
wise start to spin. This could impair the car's stability.
•Always adapt your driving style to suit road conditions and the traffic
situation.
WARNING
Modifications to the vehicle or work carried out incorrectly (e. g. to the
engine, the brake system, running gear or any components affecting the
wheels and tyres) could affect the efficiency of the ABS, EDL, ESP and TCS
and lessen their efficiency.
Electronic stabilisation programme (ESP)
The electronic stabilisation programme helps to reduce the
danger of skidding.
The electronic stabilisation programme (ESP) consists of ABS, EDL and TCS
and only works when the engine is running.
The ESP should generally be left switched on at all times. Only when the
necessary drive can not be obtained should the ESP be disconnected.
For example:
•when driving with snow chains,
WARNING (continued)

Driving and the environment 186
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. The slightly reduced braking effect can be compen-
sated for by increasing pressure on the brake pedal. 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.
•When driving downhill, the brakes work hard and get hot very quickly.
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). In this way you will make use of
the engine braking effect and relieve the load on the brakes.
•Never let the brakes “rub” by only 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 work.
•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 notes Ÿpage 202 before
buying accessories.
•If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Exhaust gasses purification system
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
Ÿpage 215, “Topping up engine oil E”.
– Never tow the vehicle to start it, use jump leads if necessary
Ÿpage 249.
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. These symptoms are indicated by the exhaust
gas warning lampŸpage 70. 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!

Cleaning and caring for your vehicle
General notes
Regular 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 temperatures (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 cleaning 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.

Safety FirstOperating instructionsTips and MaintenanceTe c h n i c a l D a t a Filter pre-heater
Your vehicle is fitted with a fuel filter pre-heater, making it well equipped for
operation in winter. This ensures that the fuel system remains operational to
approx. -24°C, provided you use winter-grade diesel which is safe to -15°C .
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24°C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (“thinners”, or similar additives) with diesel fuel.
Supplementary heating system
The supplementary heating system raises the calorific capacity of the heating
while the engine is running and outside temperatures are very low. The
supplementary heating system connects and disconnects automatically.
The exhaust fumes produced are eliminated through an exhaust pipe below
the vehicle.
Note
•For short journeys, very low outside temperatures and a percentage of
biodiesel fuel of over 50 % too much smoke may be produced.
•Every time the engine is switched off, the fan continues to operate for a
short time in order to more quickly cool the heater. When refuelling it is not
necessary to wait until the fan stops operating.
Working in the engine compartment
Safety instructions on working in the engine compartment
Any work carried out in the engine compartment or on the
engine must be carried out cautiously.
Before starting any work on the engine or in the engine compart-
ment:
1. Switch off the engine and remove the key from the ignition.
2. Apply the handbrake.
3. Move the gear stick to neutral or the selector lever to position P.
4. Wait for the engine to cool down.
5. Keep children away from the vehicle.
6. Raise the bonnet Ÿpage 97.
You should not do any work in the engine compartment unless you know
exactly how to carry out the jobs and have the correct tools! Have the work
carried out by a qualified workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs and
batteries, are being constantly developed. SEAT provides a constant flow of
information to the Authorised Service Centres concerning modifications. For
this reason we recommend that you have service fluids and consumables
replaced by an Authorised Service Centre. Please observe the relevant
instructions Ÿpage 202. The engine compartment of any motor vehicle is a
hazardous area. Ÿ.

Checking and refilling levels 210
WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger of injury and scalding as well as the risk
of accident or fire.
•Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the
engine to cool before carefully opening the bonnet.
•Switch off the engine and remove the key from the ignition.
•Apply the handbrake and move the gear stick to neutral or selector
lever to position P.
•Keep children away from the vehicle.
•Never touch hot engine parts. There is a risk of burns.
•Never spill liquids on a hot engine or on a hot exhaust gas system. This
is a fire hazard.
•Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached Ÿpage 250. The battery could
explode.
•Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!
•Do not unscrew the cap on the expansion tank when the engine is hot.
If the coolant is hot, the cooling system will be pressurised!
•Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.
•Always make sure you have not left any objects, such as cleaning cloths
and tools, in the engine compartment.
•If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
•If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belts, alternator, radiator fan, etc., and
from the high-voltage ignition system. You should also observe the
following points:
−Never touch the electrical wiring of the ignition system.
−Ensure that jewellery, loose clothing and long hair do not get
trapped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
−Always think carefully about pressing the accelerator if a gear is
engaged in either an automatic or manual gearbox. The vehicle could
move, even if the handbrake is applied. Danger of death.
•If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following safety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
−Do not smoke.
−Never work near naked flames.
−Always have a fire extinguisher on hand.
Caution
When changing or topping up service fluids, make absolutely certain that you
fill the fluids into the correct reservoirs. Failure to observe this point will result
in serious malfunctions and engine damage!

– Insert a new wiper blade of the same length and design in the
direction of arrow and hook the blade back onto the wiper
arm.
– Now pull the wiper blade against the direction of arrow until
it engages.
– Push the wiper arm back against the glass.
These are available from SEAT Service®.
If the windscreen wiper scrapes, they should be replaced if they are
damaged, or cleaned if they are soiled.
If this does not produce the desired results, the setting angle of the wind-
screen wiper arms might be incorrect. They should be checked by a qualified
workshop and corrected if necessary.
WARNING
Do not drive unless you have good visibility through all windows!
•Clean the windscreen wiper blades and all windows regularly.
•The wiper blades should be changed once or twice a year.
Caution
•Damaged or dirty windscreen wipers could scratch the windscreen.
•Never use fuel, nail varnish remover, paint thinner or similar products to
clean the windows. This could damage the windscreen wiper blades.
•Never move the windscreen wiper or windscreen wiper arm manually - this
could cause damage!
Note
•The wiper arms can be moved to the service position only when the
bonnet is properly closed.
Brake fluid
Checking the brake fluid level
The brake fluid is checked at the intervals given in the service
schedule.
– Read off the fluid level at the transparent brake fluid reservoir. It
should always be between the “MIN” and “MAX” marks.

Checking and refilling levels 222
The position of the brake fluid reservoir is shown in the corresponding engine
compartment diagram Ÿpage 262. The brake fluid reservoir has a black and
yellow cap.
The brake fluid level drops slightly when the vehicle is being used as the
brake pads are automatically adjusted as they wear.
However, if the level goes down noticeably in a short time, or drops below the
“MIN” mark, there may be a leak in the brake system. A display on the instru-
ment panel will warn you if the brake fluid level is too low Ÿpage 70.
WARNING
Before opening the bonnet to check the brake fluid level, read and observe
the warnings Ÿpage 209.
Changing the brake fluid
The brake fluid must be renewed every two years.
We recommend that you have the brake fluid changed by an Authorised
Service Centre.
Before opening the bonnet, please read and follow the warnings Ÿ in
“Safety instructions on working in the engine compartment” on page 209 in
“Working in the engine compartment”.
Brake fluid absorbs moisture. In the course of time, it will absorb water from
the ambient air. If the water content in the brake fluid is too high, the brake
system could corrode. This also considerably reduces the boiling point of the
brake fluid. Heavy use of the brakes may then cause a vapour lock which
could impair the braking effect.
For this reason the brake fluid must be renewed every two years.It is important that you use only use brake fluid compliant with the US
standard FMVSS 116 DOT 4. We recommend the use of Genuine SEAT brake
fluid.
WARNING
Brake fluid is poisonous. Old brake fluid impairs the braking effect.
•Before opening the bonnet to check the brake fluid level, read and
observe the warnings Ÿpage 209.
•Brake fluid should be stored in the closed original container in a safe
place out of reach of children. There is a toxic risk.
•Have the brake fluid 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 would seriously affect the efficiency of the brakes and the
safety of the vehicle. This may cause an accident.
Caution
Brake fluid could damage the paintwork. Wipe off any brake fluid from the
paintwork immediately.
For the sake of the environment
Brake fluid must be drained and disposed of in the proper manner observing
environmental regulations.

Checking and refilling levels227
Safety FirstOperating instructionsTips and MaintenanceTe c h n i c a l D a t a Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
Ÿpage 226, fig. 150 running across the tread. Depending on the make,
there will be six to eight of them evenly spaced around the tyre. Markings on
the tyre sidewall (for instance the letters “TWI” or other symbols) indicate the
positions of the tread wear indicators. The minimum tread depth required by
law is 1.6 mm (measured in the tread grooves next to the tread wear indica-
tors). Worn tyres must be replaced. Different figures may apply in export
countries Ÿ.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-out.
For this reason, the tyre pressure should be checked at least once per month
Ÿpage 226.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisable
to change them around as shown Ÿpage 226, fig. 151. All the tyres will then
last for about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which results
in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause excessive
wear on steering, suspension and tyres. A wheel must also be rebalanced
when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety of
the vehicle. If tyres show excessive wear, you should have the wheel align-
ment checked by an Authorised Service Centre.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!
•The tyres must be replaced at the latest when the tread is worn down to
the tread wear indicators. Failure to do so could result in an accident. Worn
tyres do not grip well at high speeds on wet roads. There is also a greater
risk of “aquaplaning”.
•At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
•If tyres show excessive wear, you should have the running gear checked
by an Authorised Service Centre.
•Keep chemicals such as oil, fuel and brake fluid away from tyres.
•Damaged wheels and tyres must be replaced immediately!
For the sake of the environment
Under-inflated tyres will increase fuel consumption.
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 Ÿ.
Tyres should be replaced at least in pairs and not individually (i.e. both front
tyres or both rear tyres together). A knowledge of tyre designations makes it
