Several warning and control lamps light up for a few seconds when the igni-
tion is switched on while a test of the function is being carried out. They will
switch off after a few seconds.
WARNING
If the warning lamps are ignored, the vehicle may stall in traffic, or may
cause accidents and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible.
WARNING
Driving with brakes in bad condition could result in a serious accident.
● If the brake warning lamp  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. Obtain professional assistance immediately
⇒ page 141, Brake fluid.
● If the brake warning lamp  lights up together with the ABS warning
lamp , the regulation function of the ABS could be malfunctioning. As a
result, the rear wheels can lock relatively easily when braking. If the rear
wheels lock this could result in loss of vehicle control! If possible, reduce 

Starting, changing gears, parking
To park the vehicle
Complete operations only in the sequence given.
● Park the vehicle on a suitable surface ⇒ 
.
● Press and hold the brake pedal until the vehicle comes to a standstill.
● Apply the handbrake firmly ⇒ page 136.
● For an automatic gearbox, move the selector lever to position P.
● Switch off the engine and release the brake pedal.
● Remove the key from the ignition.
● If necessary, turn the steering wheel slightly to lock the steering.
● With a manual gearbox, engage the 1st gear on flat ground and slopes,
or even the reverse gear on hills, and release the clutch pedal.
● Ensure that all passengers leave the vehicle, especially children.
● When leaving the vehicle, take all keys with you.
● Locking the vehicle.
Additional information for steep slopes and hills
Before switching off the engine, rotate the steering wheel so that if the vehi-
cle should move then it will be held by the kerb.
● On slopes, turn the front wheels so that they are against the edge of the
kerb.
● Uphill, turn the wheels towards the centre of the road.
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 wood, leaves, spilled
fuel, dried grass, etc).
CAUTION
● Special care should be taken when parking in areas with high kerbs or
fixed barriers. Objects protruding from the ground may damage the bumper
or other parts of the vehicle during manoeuvres. To avoid damage, stop be-
fore the wheels touched the barrier or kerb.
● Special attention is required when driving through entrances, over
ramps, kerbs or other objects. The vehicle underbody, bumpers, mudguards
and running gear, and the engine and exhaust system could be damaged as
you drive over these objects. 
Information about the brakes
For the first 200 to 300 km (120 to 190 mph), the new brake pads have not
yet reached their maximum braking capacity, and need to be “run in” first
⇒ 
. The slightly reduced braking effect can be compensated for by in-
creasing pressure on the brake pedal. While running in, the full braking dis-
tance or emergency braking distance is larger then when the brake pads
have been run in. While running in, avoid full power braking or situations
requiring braking performance. For example, in heavy traffic.
The rate of wear of the brake pads depends to a great extent on the condi-
tions in which the vehicle is used and the way the vehicle is driven. If the
vehicle is used frequently in city traffic or for short trips or driven sport style,
visit a Specialised workshop regularly more frequently than advised in the
Maintenance Programme to have the brake pads checked.
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). At higher
speed, “dry” the brakes as quickly as possible by braking gently several
times. Only do this without endangering vehicles behind you or any other
road users ⇒

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.

WARNING (Continued)
● Even though braking assist systems are extremely effective and help
control the vehicle in difficult situations, remember that the vehicle sta-
bility depends on tyre grip.
● When accelerating on a slippery surface, for example on ice and
snow, press the accelerator carefully. The wheels can still slip even with
braking assist systems resulting in loss of vehicle control.
WARNING
The effectiveness of the ESC* can be considerably reduced if other com-
ponents and systems affecting driving dynamics are not maintained or
are not functioning correctly. This includes, among others, brakes, tyres
and other systems already mentioned.
● Remember that changing and fitting other components to the vehicle
can affect operation of the ABS, BAS, ASR TC, EDL and ESC*.
● Changes to the vehicle suspension or using unapproved wheel/tyre
combinations can affect operation of the ABS, BAS, ASR, TC, EDL and
ESC* and their effectiveness.
● Likewise, the effectiveness of ESC* depends on the use of suitable
tyres ⇒ page 210.
Note
To ensure that the ESC*, ASR and TC work properly, all four wheels must be
fitted with identical tyres. Any differences in the rolling radius of the tyres
can cause the system to reduce engine power when this is not desired.
Note
If a malfunction should occur in the ABS, the ESC*, ASR, TC and EDL will al-
so be affected.
Note
Noises may be heard while any of the above systems are operating. 
Brake fluid
Fig. 91 In the engine
compartment: brake fluid
reservoir, lid
In the course of time, the brake fluid absorbs water from the ambient air. If
there is too much water contained in the brake fluid, the brake system could
be damaged. In addition, the boiling point of the brake fluid is significantly
lowered. When the brake fluid contains too much water and the brakes are
subject to considerable forces, bubbles of water vapour can form in the sys-
tem. These bubbles of water vapour can significantly reduce braking power,
notably increasing braking distance, and could even result in the total fail-
ure of the brake system. Ensuring that the brake system is always function-
ing correctly is essential for your own safety and the safety of other road
users ⇒

Moderate use of additional electrical appliances
It is important to travel in comfort, but convenience systems should be used
in an ecological manner.
Some equipment, when connected, increase fuel consumption considera-
bly, for example:
● Air conditioning cooling system: If the air conditioning system is re-
quired to cool to significantly lower temperatures than the true outside tem-
perature, it will require a large quantity of energy from the engine. There-
fore, we recommend that the selected temperature for the vehicle is not too
different to the outside temperature. It is a good idea to open all the win-
dows of the vehicle before starting your journey, and to drive a short dis-
tance with all the windows open to allow the vehicle to cool down slightly.
Only then should you close all the windows and switch on the air condition-
ing system. Keep windows closed when travelling at high speeds. Driving
with the windows open increases fuel consumption.
● Switch off the seat heating when the seats have warmed up.
● Switch off the heated rear window when it is not moist or covered in ice.
Other factors which increase fuel consumption (examples):
● Fault in engine management.
● Driving on hills. Saving fuel while driving
Fig. 92 Fuel consump-
tion in litres per 100 km
at 2 different outside
temperatures
By adopting an economical driving style and anticipating the traffic situa-
tion ahead, you can easily reduce fuel consumption by 10-15%.
A vehicle uses most fuel when accelerating. By anticipating the traffic situa-
tion ahead, you will brake and therefore accelerate less. Wherever possible,
let the vehicle roll slowly to a stop, for instance when you can see that the
next traffic lights are red.
Avoid short journeys
Fuel consumption is much higher when the engine is cold, immediately af-
ter it has been started. It takes a few kilometres of driving for the engine to
warm up and to normalise consumption.
The engine and catalytic converter need to reach their proper working tem-
perature in order to minimise fuel consumption and emissions. The ambient
temperature has a decisive influence.
Fig. 92 shows the difference in consumption for the same journey at +20 °C
(+68 °F) and at -10 °C (+14 °F). 

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.
