A layer of salt on the discs and brake pads will reduce brake efficiency and
increase braking distance. If you drive for a prolonged period on salted
roads without braking then brake carefully several times to eliminate the
layer of salt on the brakes ⇒ 
.
If the vehicle remains parked for considerable lengths of time, is used little,
or if the brakes are not used, there may be corrosion on the brake discs and
a build-up of dirt on the brake pads. If the brakes are not used frequently, or
if rust has formed on the discs, SEAT recommends cleaning the pads and
discs by braking firmly a few times at a moderately high speed. Only do this
without endangering vehicles behind you or any other road users ⇒ 
.
Faults in the brake system
During braking, if you notice that the vehicle does not react as usual (that
the braking distance has increased suddenly) it may be possible that there
is a fault in the braking system. This is indicated by the warning lamp .
Take the vehicle to a Specialised workshop immediately and have the fault
repaired. Drive at a moderate speed and be prepared to use more pressure
on the brake pedal, and allow for longer braking distances.
Brake servo
The brake servo only operates when the engine is running and the pressure
applied by the driver on the brake pedal increases.
If the brake servo does not operate or the vehicle must be towed, then the
brake pedal will have to be pressed with more force given that the braking
distance will be increased when the brake servo does not operate ⇒ 
.
WARNING
New brake pads do not brake to full efficiency.
● For the first 320 km (200 miles), new brake pads have not yet reached
their maximum braking capacity, and need to be “run in” first. For this, to
compensate for reduced braking efficiency the brake pedal will have to
be pressed with more force.
WARNING (Continued)
● To avoid losing control of the vehicle and causing serious accidents,
always take great care when driving with new brake pads.
● When running in new brake pads, always respect the safety distances
between you and other vehicles and do not cause situations requiring ex-
treme braking performance.
WARNING
When brakes overheat, braking is less efficient and braking distances in-
crease.
● When driving on slopes, brakes can be overloaded and overheat
quickly.
● Reduce speed or reduce the gear when faced with steep and long
slopes. This allows you to use the engine braking effect and to reduce
the strain on the brake system.
● Non-standard or damaged front spoilers could restrict the airflow to
the brakes and cause them to overheat.
WARNING
Wet, frozen or salt-covered brakes take time to brake and this increases
braking distances.
● Test the brakes carefully.
● Dry the brakes, free them of ice and salt by braking gently several
times, when visibility, weather, and road and traffic conditions permit. 

Starting, changing gears, parking
WARNING
Driving without the brake servo may significantly increase the braking
distance and result in a severe accident.
● Never allow the vehicle to move forwards when the engine is switched
off.
● If the brake servo does not operate or the vehicle must be towed,
then the brake pedal will have to be pressed with more force given that
the braking distance will be increased when the brake servo does not op-
erate.
CAUTION
● Never make the brakes “slip” by pressing the pedal gently, if it is not
really necessary to brake. Continuously pressing on the brake pedal will
heat the brakes. This could significantly reduce braking power, increase
braking distance or even result in the total failure of the brake system.
● Reduce speed or reduce the gear when faced with steep and long
slopes. This allows you to use the engine braking effect and to reduce the
strain on the brake system. Otherwise, the brakes may overheat and fail.
Only use the brakes to reduce speed or to stop.
Note
Make use, when having the front brake pads checked, and have the rear
pads checked also. The thickness of the brake pads should be checked vis-
ually and regularly, by looking through the openings in the wheel rims or
from underneath the vehicle. If necessary, remove the wheels to check them
thoroughly. SEAT recommends visiting a Technical Service. Assisted braking systems
The assisted braking systems ESC*, ABS, EBV, BAS, ASR, TC and EDL only
operate when the ignition is switched on. They contribute significantly to in-
creasing active safety.
Electronic Stability Control (ESC)*
ESC* reduces the risk of skidding and increases the vehicle stability by
braking individual wheels under specific driving conditions. ESC* detects
critical handling situations, such as understeer, oversteer and wheelspin on
the driven wheels. The system stabilises the vehicle by braking individual
wheels or by reducing the engine torque.
The ESC* has limits. It is important to realise that the ESC* is also subject to
the laws of physics. ESC* will not be able to deal with all situations with
which drivers may be faced. For example, if the road surface changes sud-
denly then ESC* will not be useful in all cases. If the vehicle suddenly enters
a section covered by water, mud or snow then ESC* will not provide assis-
tance in the same way as on dry ground. If the vehicle loses its grip on the
ground and moves on a film of water (“aquaplaning”), the ESC* will not be
able to assist the driver to control the vehicle due to the loss of adherence
with the road surface preventing braking and steering. If the vehicle is driv-
en through series of bends at high speed, the ESC* will not always be as
effective: the vehicle reaction to aggressive driving is not the same as at re-
duced speeds.
Adjust your speed and driving style to suit visibility, and weather, road and
traffic conditions. ESC* cannot push the limits of the laws of physics; im-
prove the transmission available or maintain the vehicle on the road if a
lack of driver attention creates an inevitable situation. Otherwise, ESC* as-
sists in maintaining vehicle control in extreme situations and uses the
movements of the steering made by the driver to maintain the vehicle mov-
ing in the desired direction. If the vehicle is driven at such a speed that it
will leave the road before ESC* can intervene then the system cannot pro-
vide assistance.

Steering Introduction
The power steering* is not hydraulic but electromechanical. The advantage
of this steering system is that it disposes of hydraulic tubes, hydraulic oil,
the pump, filter and other components. The electromechanical system
saves fuel. While a hydraulic system requires oil pressure to be maintained,
electromechanical steering only requires energy when the steering wheel is
turned.
With the electromechanical steering system, the power steering function au-
tomatically adjusts according to the vehicle speed, the steering torque and
the wheel turning angle. The electromechanical steering only works when
the engine is running.
Additional information and warnings:
● Start and stop the engine ⇒ page 119
● Vehicle battery ⇒ page 193
● Tow-starting and towing away ⇒ page 276
WARNING
If the power steering is not working then the steering wheel is much
more difficult to turn and the vehicle more difficult to control.
● The power steering only works when the engine is running.
● Never allow the vehicle to move when the engine is switched off.
● Never remove the key from the ignition if the vehicle is in motion. The
steering may lock and it will not be possible to turn the steering wheel.

The windscreen wiper blades are supplied as standard with a layer of graph-
ite. This layer is responsible for ensuring that the wipe is silent. If the graph-
ite layer is damaged, the noise of the water as it is wiped across the wind-
screen will be louder. Check the condition of the wiper blades regularly.
If the wipers scrape
across the glass they should be changed if they are damaged, or cleaned if
they are dirty ⇒ 
.
Damaged wiper blades should be replaced immediately. Blades are availa-
ble from Specialised workshops.
Lifting and unfolding the wiper arms
The wiper arm may only be lifted at the point where it is fastened to the
blade.
For windscreen wipers, please note: the windscreen wiper should be in
service position before unfolding it ⇒ page 91.

Retro-fitting of two-way radios
An exterior aerial is required for the use of two-way radios in the vehicle.
The retro-fitting of electrical or electronic appliances in the vehicle is sub-
ject to their approval for use in your vehicle. Under certain circumstances,
this could mean that your vehicle registration documents are no longer val-
id.
SEAT has approved your vehicle for use with two-way radios providing the
following conditions are observed:
●The exterior aerial must be mounted professionally.
● The maximum transmitting power is 10 watts.
An only external aerial is needed to give the equipment its optimal reach.
Check first with a Specialised workshop if you wish to use a two-way radio
with a transmitting power of over 10 watts. The Specialised workshops are
familiar with the technical options for installation. SEAT recommends visit-
ing a Technical Service.
All legal requirements, together with the instructions for the use of two-way
radios must be observed.
WARNING
If the two-way radio is not securely fastened in position, it could be sent
flying around the vehicle in the event of sharp braking, sudden manoeu-
vres or accident, causing injury.
● While driving, two-way radios must be securely fastened in position,
outside the airbags deployment zones, or safely stowed away.
WARNING
When using a two-way radio without a connection to an exterior aerial,
the maximum permitted levels of electromagnetic radiation may be ex-
ceeded. This is also the case if the aerial has not been correctly installed.
● You should only use a two-way radio inside the vehicle if it has first
been correctly connected to an exterior aerial.

Information stored by the control units
Your vehicle is fitted at the factory with a series of electronic control units
responsible for the engine and gearbox management. In addition, the con-
trol units supervise the performance of the exhaust gas system and the air-
bag systems.
Therefore, while the vehicle is being driven, these electronic control units
are continuously analysing the vehicle data. In the event of faults or devia-
tions from the theoretical values, only this data is stored. Normally, the
warning lamps on the instrument panel light up in the event of faults.
This data can only be read and analysed using special equipment.
The storing of the data allows specialised workshops to detect and repair
faults. Stored data may include:
● Data relating to the engine or the gearbox
● Speed
● Direction of travel
● Braking force
● Detection of seat belt
The vehicle control units never record conversations held by passengers in
the vehicle. 

Vehicle care and maintenance
Catalytic converter
The catalytic converter permits the subsequent treatment of the exhaust
gases thus reducing contaminating gas emissions. To ensure a longer work-
ing life for the exhaust system and catalytic converter in a petrol engine:
● Always use unleaded petrol.
● Never run the fuel tank completely dry.
● Do not top up with too much engine oil ⇒ page 185.
● Do not tow-start the vehicle; use the starter cables ⇒ page 273.
If you should notice misfiring, uneven running or loss of power when the ve-
hicle is moving, reduce speed immediately. Have the vehicle inspected by a
Specialised workshop. If this happens, unburnt fuel can enter the exhaust
gas system and escape into the atmosphere. The catalytic converter can al-
so be damaged by overheating.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel used. 

Practical information
Checklist (Continued) 7. When leaving the vehicle, take all keys with you.
8. Place an emergency warning triangle to indicate the position of your vehicle to other road users.
9. Allow the engine to cool and check if a specialist is required.
When being towed with the hazard warning lights system on, a change in
direction or traffic lane can be indicated as usual using the turn signals lev-
er. The hazard lights will be interrupted temporarily.
Examples of when to use the hazard warning lights system:
● If the vehicles ahead suddenly slow down or reach the end of a traffic
jam, to warn the vehicles behind.
● In case of an emergency.
● If the vehicle breaks down.
● When tow-starting or towing.
Always comply with the applicable laws regarding the use of hazard warn-
ing lights.
If the hazard warning lights system is not working, you must use an alterna-
tive method of drawing attention to your vehicle. This method must comply
with traffic legislation.
WARNING
Failure to follow the checklist prepared for your own safety could lead to
accidents and severe injuries.
● Always complete the operations given in the checklist and observe
the general rules of safety.
WARNING
The components of the exhaust system reach very high temperatures.
This could cause a fire and considerable damage.
● Always park your vehicle so that no part of the exhaust system can
come in contact with flammable materials (such as dried grass or fuel).
Note
The vehicle battery will discharge and run down if the hazard warning lights
remain on for too much time (even with the ignition turned off).
Note
For some vehicles, the brake lights will blink when braking suddenly at
speeds of approximately 80 km/h (50 mph) to warn vehicles behind. If brak-
ing continues, then the hazard warning lights system will automatically be
turned on at the speed of less than approximately 10 km/h (6 mph). The
brake lights remain lit. Upon accelerating, the hazard warning lights system
will be automatically turned off. 
