Alternator 
This warning lamp signals a fault in the alternator.
The warning lamp  lights up when the ignition is switched on. It should
go out when the engine has started running.
If the warning lamp  lights up while driving, the alternator is no longer
charging the battery. You should immediately drive to the nearest special-
ised workshop.
You should avoid using electrical equipment that is not absolutely necessa-
ry because this will drain the battery. 
Worn brake pads 
If the  symbol lights up, have the front brake pads (and, for safety rea-
sons, the rear pads as well) inspected by a specialised workshop. Tyre pressure 
The tyre pressure control system controls the tyre speed and
the frequency spectrum of each tyre.

Driving
Handbrake Using the handbrake
The handbrake should be applied firmly to prevent the vehi-
cle from accidentally rolling away.
Fig. 129 Handbrake be-
tween the front seats
Always apply the handbrake when you leave your vehicle and when
you park.
Applying the handbrake
– Pull the handbrake lever up firmly ⇒ fig. 129.
Releasing the handbrake
– Pull the lever up slightly and press the release knob in the di-
rection of the arrow ⇒ fig. 129 and guide the handbrake lever
down fully ⇒ 
. Always apply the handbrake
as far as it will go in order to prevent you from
driving with the handbrake applied by mistake ⇒ 
.
The handbrake warning lamp  lights up when the handbrake is applied
and the ignition switched on. The warning turns off when the handbrake is
released.
If you drive faster than 6 km/h with the handbrake on, the following mes-
sage* will appear on the instrument panel display: HANDBRAKE ON. You will
also hear an acoustic warning signal.
WARNING
● Never use the handbrake to stop the vehicle when it is in motion. The
braking distance is considerably longer, because braking is only applied
to the rear wheels. Risk of accident!
● If it is only partially released, this will cause rear brakes overheating,
which can impair the function of the brake system and could lead to an
accident. This also causes premature wear on the rear brake pads.
CAUTION
Always apply the handbrake before you leave the vehicle. The first gear
should also be selected. 
Parking
The handbrake should always be firmly applied when the
vehicle is parked.
Always note the following points when parking the vehicle:
– Use the brake pedal to stop the vehicle.
– Apply the handbrake. 

186Intelligent technology
To prevent the disc brake of the braking wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. The vehicle will con-
tinue to function normally without EDL. For this reason, the driver is not in-
formed 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 tak-
ing any risks when driving, this can cause accidents.
CAUTION
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 EDL ⇒ page 208. 
Traction control system ASR (TCS)
The traction control system prevents the drive wheels from spinning when
the vehicle is accelerating ⇒ page 183. 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; first they must be run in. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. Avoid overload-
ing 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
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.
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.
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. 

187
Intelligent 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.
Brake servo
The brake servo increases the pressure you apply to the brake pedal. The
brake servo works only when the engine is running.
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.
● Ensure the vehicle does not move while in neutral, when the engine is
stopped. Failure to do so could result in an 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 the brake servo is not functioning due to a malfunction, or if the vehi-
cle has to be towed, you will have to press the brake pedal considerably
harder to make up for the lack of servo assistance.
● 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. 
Power steering (servotronic*)
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. In cars equipped with servotronic* power steering the de-
gree of power assistance is regulated electronically according to road
speed.
The power steering will keep on working in spite servotronic* device fails.
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 in-
stance when parking), as more effort will be required than usual. The fault
should be corrected by a specialised workshop as soon as possible.
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 

Running-in Running in a new engine
The engine needs to be run in over the first 1500 km.
Up to 1000 kilometres
– Do not drive at speeds of more than 2/3 the maximum speed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1000 to 1500 kilometres
– 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 friction 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, its life will be increased and its oil consump-
tion reduced. Braking capacity and braking distance
The braking capacity 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 Authorised Service Centre more frequently than recommen-
ded in the Service Plan.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the vehicle, the effect of the brakes is
lessened as the brake discs are wet or even frozen (in winter). In this case
the brakes should be dried by pressing the brake pedal several times.
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 400 km. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also ap-
plies when the brake pads have to be changed further on.
● If brakes are wet or frozen, or if you are driving on roads which have
been salted, braking power may be lower than normal. 

200Vehicle 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.
CAUTION
If an automatic car wash tunnel is used, before entering the tunnel, put the
aerial down parallel to the roof and do not tighten to avoid damage. 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 189, Braking capacity
and braking distance. 

Checking and refilling levels
Brake fluid Checking the brake fluid level
The brake fluid is checked at the intervals given in the serv-
ice schedule.
Fig. 151 In the engine
compartment: Brake fluid
reservoir cover
– Read off the fluid level at the transparent brake fluid reservoir. It
should always be between the “MIN” and “MAX” marks.
The position of the brake fluid reservoir is shown in the corresponding en-
gine compartment illustration ⇒ page 273. 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
instrument panel will warn you if the brake fluid level is too low ⇒ page 77.
WARNING
Before opening the bonnet to check the brake fluid level, read and ob-
serve the warnings ⇒ page 217.

Changing the brake fluid
The Maintenance Programme indicates the brake fluid
change intervals. We recommend that you have the brake fluid changed by an Authorised
Service Centre.
Before opening the bonnet, please read and follow the warnings ⇒ 
in
Safety instructions on working in the engine compartment on page 217 in
section “Safety notes for 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.
It is important that you use only brake fluid compliant with 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 ob-
serve the warnings ⇒ page 217. 

230Checking and refilling levels
WARNING (Continued)
● Brake fluid should be stored in the closed original container in a safe
place out of reach of children. There is a toxic risk.
● Complete the brake fluid change according to the Maintenance Pro-
gramme. 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 effi-
ciency of the brakes and the safety of the vehicle. This may cause an ac-
cident.
CAUTION
Brake fluid could damage the paintwork. Wipe off any brake fluid from the
paintwork immediately.
For the sake of the environment
The brake pads and fluid must be collected and disposed of according the
applicable regulations. The SEAT Technical Service network has the neces-
sary equipment and qualified personnel for collecting and disposing of this
waste material. 
