NoteIf the ABS warning lamp lights up, this can also mean there is a fault in the
EDL. Please take the vehicle to a qualified workshop as soon as possible.Traction control system (TCS)
The traction control system prevents the drive wheels from
spinning when the vehicle is accelerating.General notes
The traction control system (TCS) is one of the functions incorporated in the
Electronic Stability Programme (ESP).
The traction control system (TCS) helps the vehicle to start moving, accelerate
or climb a gradient in slippery conditions where this may otherwise be diffi-
cult or even impossible.
How it works
The TCS acts automatically, without the driver’s intervention. With the aid of
the ABS sensors ⇒page 186, the TCS monitors the speed of the drive
wheels. If the wheels start to spin, the engine speed is reduced automatically
to match the amount of grip available. The system is active across the entire
speed range.
The TCS works in conjunction with the ABS. If a malfunction occurs in the ABS,
the TCS will also be inoperative.
Note
To ensure that the TCS works properly, all four wheels must be fitted with
identical tyres. The difference in size of the wheels may lead to an undesired
reduction in engine power. Also see ⇒page 244.

Intelligent technology
190and 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 you wish to equip the vehicle 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.Brake servo
The brake servo assists the driver when brakingThe brake servo increases the pressure you apply to the brake pedal. The
brake servo works only when the engine is running.
WARNING
Ensure the vehicle does not move while in neutral, when the engine is
stopped. Failure to do so could result in an accident.
Note
If the brake servo is not working, e.g. because the vehicle has to be towed or
because it is broken, you will have to press the brake pedal considerably
harder to make up for the lack of servo assistance.
Power steeringPower steering makes it easier to turn the steering wheel
when the engine is running.Power steering assists the driver by reducing the force needed to turn the
steering wheel.
Power steering does not work if the engine is off. In this case the steering
wheel requires much more force to turn.
If the steering is held at its turning limit when the vehicle is stationary, this
will place an excessive load on the power steering system. Turning the
steering wheel to its limit places a load on the system, which causes noise. It
will also reduce the idling speed of the engine.
Caution
When the engine is running, do not turn the steering wheel to its limit 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 vehicle 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 vehicle to a
qualified workshop as soon as possible.•The power steering system requires a special hydraulic fluid. The fluid
reservoir is located at the front of the engine compartment on the left
⇒ page 295. 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.

Servotronic*The servotronic system electronically adjusts the power
assisted steering.In vehicles equipped with servotronic power steering the degree of power
assistance ⇒page 190 is adjusted 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 regulating system is not working properly,
this is most noticeable when turning the steering wheel at low speeds (for
instance when parking), as more effort will be required than usual. The fault
should be corrected by a qualified workshop as soon as possible.

Trailer towing199
Safety First
Operating Instructions
Practical Tips
Technical Specifications
Where possible, operate the trailer with the maximum permitted
drawbar
load on the ball joint of the towing bracket, but do not exceed the specified
limit.
Tyre pressure
Check the tyre pressures on your vehicle, and adjust for “full load” conditions
(refer to the sticker listing the tyre pressures on the door pillar). It may also be
necessary to adjust the tyre pressures on the trailer according to the recom-
mendations of the trailer manufacturer.
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. The two exterior mirrors should be fitted on folding arms. Adjust the
mirrors to give sufficient rear vision.
Headlights
Before starting a journey, check the headlight beam settings with the trailer
hitched up. If necessary, alter the height of the headlight beams by means of
the headlight range control. See ⇒page 119.
Power supply
When you remove the ignition key, the power supply to the trailer is inter-
rupted.
Removable ball joint coupling
Vehicles with a factory-fitted towing bracket are equipped with a removable
ball joint coupling. This is stored in the spare wheel well in the luggage
compartment together with the necessary fitting instructions.
Note
If you frequently tow, we recommend you also have the vehicle serviced
between services.
Notes on towing
Towing a trailer involves additional attention by the driver.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slow to allow for
the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. There-
fore, it is advisable not to drive at the maximum permissible speed in unfa-
vourable road, weather or wind condit ions. This especially applies when
driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of swaying . Never try to stabilise the trailer by accelerating.
Anticipate hazards and brake in good time. If towing a trailer with an inertia
brake , first brake gently and then harder. This will prevent brake tapping by
the trailer wheels when they lock. 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.
Swaying and pitching can be reduced by stabiliser aids. We recommend
having stabiliser aids installed when towing trailers with a high trailer weight.
They can be purchased and installed at a Technical Service.
Reheating
When climbing long hills in hot weather with the engine running fast in low
gear, you should keep an eye on the coolant temperature gauge ⇒page 60.
Reduce speed immediately if the needle moves to the right end of the scale.
If the temperature warning lamp
v in the instrument panel should start
flashing, stop the vehicle and let the engine cool down by running it at idling
speed for a few minutes.

Removable towing bracketIntroduction
Special care is required when fitting and removing the towing
bracket.The removable ball joint attachment for the towing bracket is stored under the
floor panel in the luggage compartment.•Vehicles with a spare wheel ⇒ fig. 151.
The ball joint can be fitted and removed by hand.
Accessories mounted on the towing bracket
Please note that the ball joint attachment can be damaged by using unsuit-
able equipment that is mounted onto the towing bracket (e.g. bicycle rack).
Due to the material construction, such damage to the towing bracket dramat-
ically increases safety risks and in extreme cases could lead to breakage of
the towing bracket while towing ⇒. Therefore,
before buying such equipment, ensure that it is suitable for
mounting onto the vehicle’s towing bracket and that it is approved for this
purpose. To prevent damage to the ball joint from unsuitable equipment, we
recommend that equipment for the towing bracket be purchased through
your SEAT Dealer. Also see ⇒page 218.
WARNING
•Only mount equipment on the towing bracket of your vehicle if you are
certain it will not damage the bracket. The use of unsuitable accessories
can result in severe damage to the towing bracket, which could break while
pulling a trailer. Risk of accident.•Never use tools of any kind when fitting and removing the ball joint.
This would damage the locking device, no longer guaranteeing the correct
working order of the bracket. This could lead to an accident.Note
•Do not attempt to modify or repair the ball joint or other towing bracket
components.•Should you have any difficulties when using the towing bracket, or
suspect that it is not fitted properly, contact a qualified workshop.•Before setting off, always check that the ball joint is secured properly
⇒ page 204.•Never disengage the ball joint with the caravan / trailer still hitched or
with a bicycle rack or similar accessory still attached.•It is advisable to remove the ball joint when you are not towing a trailer.
Make sure that the cover piece is properly fitted on the mounting fixture on
the vehicle.•Remove the ball joint before washing the vehicle with pressurised steam
equipment. Make sure the cover piece is fitted correctly onto the mounting
fixture.

Vehicle maintenance and cleaning
210Vehicle exterior maintenanceAutomatic car wash tunnel
The vehicle can normally be washed without problem in an
automatic car wash.The vehicle paintwork is so durable that the vehicle can normally be washed
without problems in an automatic car wash tunnel. However, the paintwork
wear depends to a large extent on the kind of the car wash tunnel, the
brushes used, its water filtering and the type of cleaning and preservative
products.
Before going through a vehicle wash, be sure to take the usual precautions
such as closing the windows and sunroof.
If the vehicle has special accessories such as spoilers or a roof rack or two-
way radio aerial, etc., it is advisable to consult the car wash tunnel operator.
After washing, the brakes could take some time to respond as the brake discs
and pads could be wet, or even frozen in winter. Dry the brakes by braking
several times.
WARNING
Water, ice and salt on the brakes can reduce braking efficiency. Risk of
accident.Washing by handVehicle washing
– First soften the dirt with plenty of water and rinse it off. – Clean your vehicle from top to bottom with a soft sponge, a glove
or a brush. Use very light pressure.
– Rinse the sponge or glove often with clean water.
– Special car shampoo should only be used for very stubborn dirt.
– Leave the wheels, sill panels etc. until last, using a different sponge or glove.
– Rinse the vehicle thoroughly with water.
– Dry the vehicle surface gently with a chamois leather.
–In cold temperature , dry the rubber seals and their surfaces to
prevent them from freezing. Apply silicone spray to the rubber
seals.
After washing
– After washing, avoid sudden and sharp braking. Dry the brakes by braking several times ⇒page 192, “Braking capacity and
braking distance”.
WARNING
•Wash your vehicle with the ignition switched off.•Protect your hands and arms from cuts on sharp metal edges when
cleaning the underbody, the inside of the wheel housings etc. Risk of
injury.•Water, ice and salt on the brakes can reduce braking efficiency. Risk of
accident.

214Steel wheel rims– Clean steel wheel rims regularly using a separate sponge.Use an industrial cleaner to remove brake dust. Any damage to the paint on
steel wheel rims should be repaired before starting to rust.
WARNING
•Never wash tyres with a cylindrical jet. Even at large spraying distances
and short cleaning times, visible and invisible damage can occur to the
tyres. This may cause an accident.•Water, ice and salt on the brakes can reduce braking efficiency. Risk of
accident. Directly after washing, avoid sudden and sharp braking. Dry the
brakes by braking several times ⇒page 192.
Alloy wheel rimsEvery two weeks
– Wash salt and brake dust from alloy wheels.
– Use an acid free detergent to clean the wheel rims.
Every three months
– Apply a hard wax compound to the wheels.Alloy wheels require regular attention to preserve their appearance. If road
salt and brake dust are not often removed, the aluminium finish will be
impaired.
Always use an acid-free detergent for alloy wheel rims. Car polish or other abrasive agents should not be used. If the protective
coating is damaged, e.g. by flying stones, the damaged area should be
repaired immediately.

Underbody protection
The vehicle underbody is coated to protect it from chemical
and mechanical damage.The protective coating can be damaged when driving. We recommend you to
check the protective coating under the body and on the running gear, and
reinstated if necessary, before and after the winter season.
We recommend you to go to your Authorised Service Centre to carry out repair
work and additional anti-corrosion work.
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converter or the heat shields on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite. Risk of fire.

Cleaning the engine compartment
Take special care when cleaning the engine compartment.Anti-corrosion treatment
The engine compartment and the surface of the power unit are given anti-
corrosion treatment at the factory.
Good corrosion protection is particularly important in winter when the vehicle
is frequently driven on salted roads. To prevent the salt corroding the vehicle,
the entire engine compartment should be thoroughly cleaned before and
after winter.
Yo u r A u t h o r i s e d S e r v i ce Ce n t re has got the necessary equipment to provide
the correct cleaning and preserving products. For this reason, we recommend
having this work performed by them.
The anti-corrosion protection is usually removed if the engine compartment
is cleaned with grease removing solutions, or if you have the engine cleaned.
On commissioning this work, ensure that all surfaces, seams, joints and
components in the engine compartment are given anti-corrosion treatment.
WARNING
•When working in the engine compartment, always observe the safety
warnings ⇒page 224.•Before opening the bonnet, switch the engine off, apply the handbrake
firmly and always remove the key from the ignition.•Allow the engine to cool before you clean the engine compartment.•Do not clean the vehicle underbody, wheel arches or wheel trims
without protecting your hands and arms. You may cut yourself on sharp-
edged metal parts. Failure to comply could result in injury.•Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident. Directly after washing, avoid sudden and sharp braking.
•Never touch the radiator fan. It is temperature-controlled and could
start automatically, even when the key is removed from the ignition!For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed.
The polluted water must be cleaned in an oil separator. For this reason,
engine washing should be carried out only by a qualified workshop or a petrol
station.Vehicle interior maintenancePlastic parts and dash panel cleaning– Use a clean, damp cloth to clean plastic parts and the dash panel.
– If this does not provide satisfactory results, use a special solvent-free plastic cleaning product.
WARNING
Never clean the dash panel and the airbag module surface with cleaners
containing solvents. Solvents cause the surface to become porous. If the
airbag triggered, plastic parts could become detached and cause injuries.
Caution
Cleaning products which contain solvents will damage the material.

Wheels and tyres
238Wheels and tyresWheelsGeneral notesAvoiding damage
– If you have to drive over a kerb or similar obstacle, drive very
slowly and at a right angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage (cuts, cracks or blisters, etc.). Remove any foreign objects embedded in the treads.
Storing tyres
– Mark tyres when you remove them to indicate the direction of rotation. This ensures you will be able to install them correctly
when you replace them.
– When removed, the wheels and/or tyres should be stored in a cool, dry and preferably dark location.
– Store tyres in a vertical position if they are not fitted on wheel rims.New tyres
New tyres have to be run in.
The tread depth of new tyres may vary, according to the type and make of tyre
and the tread pattern. Concealed damage
Damage to tyres and rims is often not readily visible. If you notice unusual
vibrations or the vehicle pulling to one side, this may indicate that one of the
tyres is damaged. The tyres should be checked immediately by an Authorised
Service Centre.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with
directional tread. Always observe the direction of rotation indicated when
fitting the wheel. This guarantees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
WARNING
•New tyres do not have maximum grip during the first 500 km. Drive
particularly carefully to avoid possible accidents.•Never drive with damaged tyres. This may cause an accident.•If you notice unusual vibrations or if the vehicle pulls to one side when
driving, stop the vehicle immediately and check the tyres for damage.
Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the tank flap.1. Read the required tyre inflation pressure from the sticker. The values refer to Summer tyres. For Winter tyres, you must add 0.2
bar to the values given on the sticker.

2. The tyre pressures should only be checked when the tyres are
cold. The slightly raised pressures of warm tyres must not be
reduced.
3. Adjust the tyre pressure to the load you are carrying.Tyre pressure
The correct tyre pressure is especially important at high speeds. The pressure
should therefore be checked at least once a month and before starting a
journey.
The sticker with the tyre pressure values can be found on the inside of the
tank flap. The tyre pressure values given are for cold tyres. Do not reduce the
slightly raised pressures of warm tyres ⇒.
WARNING
•Check the tyre pressure at least once per month. Checking the tyre
pressure is very important. If the tyre pressure is too high or too low, there
is an increased danger of accidents - particularly at high speeds.•A tyre can easily burst if the pressure is too low, causing an accident!•At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.•If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!For the sake of the environment
Under-inflated tyres will increase fuel consumption.
Tyre pressure monitoring*
The tyre pressure monitoring system constantly checks the
pressure of the tyres.The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument panel display.
Note that tyre pressure also depends on tyre temperature. Tyre pressure
increases about 0.1 bar for each 10°C in tyre temperature increase. The tyre
heats up while the vehicle is being driven and the tyre pressure will rise
accordingly. For this reason, you should only adjust the tyre pressures when
they are cold (i.e. approximately at ambient temperature).
To ensure that the tyre pressure monitoring system works reliably, you should
check and, if necessary, adjust the tyre pressures at regular intervals and
store the correct pressures (reference values) in the system.

WARNING
•Never adjust tyre pressure when the tyres are hot. This may damage or
even burst the tyres. Risk of accident!•An insufficiently inflated tyre flexes a lot more at high speeds and
causes significant heating of the tyre. Under these conditions, the tyre
bead may be released or the tyre may burst. Risk of accident!For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear.
