Brake assist system
The brake assist system helps the driver to achieve optimum
braking effect.
The brake assist system helps to increase braking power and thus to ach-
ieve a shorter stopping distance. If the driver presses the brake pedal very
quickly, the brake assist system automatically boosts the braking force to
the maximum level, up to the point where the anti-lock brake function (ABS)
intervenes to stop the wheels from locking. You should then keep the brake
pedal pressed until the vehicle has braked to the required speed. The brake
assist system switches itself off as soon as you release the brake pedal.
The brake assist system will not be operative if there is a malfunction in the
ABS or the ESP.
WARNING
Please remember that the accident risk always increases if you drive too
fast, especially in corners or on a slippery road, or if you follow too close
behind the vehicle in front of you. An increased accident risk cannot be
compensated even by the brake assist system. Risk of accident.

Electronic differential lock (EDL)
The electronic differential lock prevents the loss of traction
caused if one wheel starts spinning. General notes
The electronic differential lock (EDL) helps the vehicle to start moving, ac-
celerate and climb a gradient in slippery conditions where this may other-
wise be difficult or even impossible. How it works
The EDL works automatically, without the driver's involvement. With the aid
of the ABS sensors, the system monitors the rotational speed of the drive
wheels
⇒ page 191. If a considerable difference in revs is detected (approx.
100 rpm) in the speed of the drive wheels, e.g. when only one part of the
surface supporting the wheels is slippery, the system applies the brake to
slow down the skidding wheel so that more of the power is directed to the
other wheels. The systems works up to a speed of approx. 80 km/h. The
system will make noise while it is working.
Starting the vehicle
If one wheel has less grip and starts spinning (for instance, if one of the
drive wheels is on ice), keep pressing the accelerator gradually until the ve-
hicle starts moving.
Overheating of the brakes
To prevent the brake disk of the braked wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. In this case, the vehi-
cle will continue to run and will have the same running properties as those
of another without EDL.
The EDL will switch on again automatically when the brake has cooled
down.
WARNING
● When accelerating on a uniformly slippery surface (for instance all
four wheels on ice or snow), press the accelerator gradually and careful-
ly. Despite EDL, the drive wheels may otherwise start to spin. This could
impair the vehicle's stability. Risk of accident.
● Even with EDL, you should always 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. Failure to do so could result in an accident. 

Intelligent technology
Note
If the ABS warning lamp lights up, this can also mean there is a fault in the
EDL. Take the vehicle to a specialised 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, acceler-
ate or climb a gradient in slippery conditions where this may otherwise be
difficult or even impossible.
How it works
The TCS acts automatically, without the driver's intervention. With the aid of
the ABS sensors ⇒ page 191, the TCS monitors the speed of the drive
wheels. If the wheels start to spin, the engine speed is reduced automati-
cally 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 unde-
sired reduction in engine power. Also see ⇒  page 247.Brakes
General notes
New brake pads
New brake pads do not provide optimal performance during the first 200
km; first 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
instance, city traffic, frequent short trips or hard driving with abrupt starts
and stops.
Wet roads or road salt
In certain conditions, such as in heavy rain, or after washing the vehicle or
driving through water, the full braking effect can be delayed by moisture (or
in winter by ice) on the discs and brake pads. In this case the brakes should
be dried by pressing the brake pedal several times.
When the speed is over 80 km/h and the windscreen wipers are on, the
brake system moves the pads towards the brake discs for a few seconds.
This occurs - without the driver knowing - at regular intervals and allows a
faster response from the brakes when driving on wet roads.
The effectiveness of the brakes can also be temporarily reduced if the vehi-
cle 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 corrosion to form on the discs and dirt to build
up on the brake pads if the vehicle is used infrequently or the brakes are
not used very often. 
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

194Intelligent technology
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 at 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
specialised workshop and have the fault repaired. Drive there slowly and re-
member that you will have to apply more pressure on the brake pedal and
allow for longer stopping 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.
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.
CAUTION
● Never let the brakes “drag” by leaving your foot on the pedal when it is
not necessary to brake. This overheats the brakes, resulting in longer stop-
ping distances and greater wear.
● Before driving down a long, steep gradient, it is advisable to reduce
speed and change to a lower gear (or move the gear lever to a lower gear
position if your vehicle has automatic transmission). This makes use of en-
gine braking and 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 braking
The 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 steering
Power 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. 

195
Intelligent technology
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
specialised 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 296. The correct fluid level in the reservoir is important for the pow-
er steering to function properly. The hydraulic fluid level is checked at the
Inspection Service. 
Servotronic*
The servotronic system electronically adjusts the power as-
sisted steering.
In vehicles equipped with servotronic power steering the degree of power
assistance ⇒ page 194 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 specialised workshop as soon as possible. 

202Trailer towing
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” condi-
tions (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
recommendations 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 be-
tween 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.
Therefore, it is advisable not to drive at the maximum permissible speed in
unfavourable road, weather or wind conditions. This especially applies
when driving downhill.
You should always reduce speed immediately if the trailer shows the slight-
est 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 go-
ing 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  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. 

204Trailer towing
Removable towing bracket
Introduction
Special care is required when fitting and removing the tow-
ing bracket.
Fig. 162 Luggage com-
partment: Spare wheel
with 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. 162.
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 dra-
matically 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 220.
WARNING
● Only mount equipment on the towing bracket of your vehicle if you
are certain it will not damage the bracket. Use of unsuitable equipment
can result in severe damage to the towing bracket. The towing bracket
could then break while pulling a trailer and cause an accident.
● Never use tools of any kind when fitting and removing the ball joint.
This would damage the locking device, no longer guaranteeing the cor-
rect 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 sus-
pect that it is not fitted properly, contact a qualified workshop.
● Before setting off, always check that the ball joint is secured properly
⇒ page 207.
● 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. 

212Vehicle maintenance and cleaning
Care of the vehicle exterior
Automatic 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 hand
Vehicle washing
– First soften the dirt and rinse it off with water. –
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 the vehicle
– After washing, avoid sudden and sharp braking. “Dry” the
brakes by braking several times ⇒ page 196, 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 in-
jury.
● Water, ice and salt on the brakes can reduce braking efficiency. Risk
of accident. 

Vehicle maintenance and cleaning
CAUTION
● Never use warm or hot water to remove snow and ice from windows and
mirrors. This could cause the glass to crack!
● The heating element for the rear window is located on the inner side of
the window. To prevent damage, do not put stickers on the heating ele-
ments inside the window. 
Cleaning windscreen wiper blades
Clean wiper blades improve visibility.
1. Use a soft cloth to remove dust and dirt from the windscreen wiper blades.
2. Use window cleaner to clean the windscreen wiper blades. Use a sponge or a cloth to remove stubborn dirt. 
Rubber seals maintenance
If rubber seals are well looked after, they will not freeze so
quickly. 1. Use a soft cloth to remove dust and dirt from the rubber seals.
2. Apply a specialist care product to the rubber seals.
The rubber strips on the doors, windows, bonnet and tailgate will remain
pliable and last longer if they are treated with a suitable care product (for
example silicone spray). Caring for rubber seals will also prevent premature ageing and leaks. The
doors will be easier to open. If rubber seals are well looked after, they will
not freeze so quickly in winter.

Door lock cylinders
The door lock cylinders can freeze up in winter.
To de-ice the lock cylinders you should only use spray with lubricating and
anti-corrosive properties. 
Cleaning chrome parts
1. Clean chrome parts with a damp cloth.
2. Polish chrome parts with a soft, dry cloth. If this does not provide satisfying results, use a specialist chrome cleaning
product. Chrome cleaning products will remove stains from the surface.
CAUTION
To prevent scratching chrome surfaces:
● Never use an abrasive cleaning product on chrome.
● Do not clean or polish chrome parts in a sandy or dusty environment. 
Steel wheel rims
– Clean steel wheel rims regularly using a separate sponge. 
