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.

The ABS, BAS, ASR and EDL systems are incorporated into the ESC*. The
ESC* is always on 1)
.
Anti-lock brake system (ABS)
ABS can prevent the wheels from locking during braking until just before
the vehicle stops thus helping the driver to steer the vehicle and maintain
control. This means that, even during full braking, the risk of skidding is re-
duced:
● Press and hold the brake pedal fully. Do not remove your foot from the
brake pedal or reduce braking force!
● Do not “pump” the brake pedal, or reduce braking force!
● Maintain vehicle direction when braking fully with the brake pedal.
● When the brake pedal is released or when the brake force is reduced,
ABS is turned off.
ABS control can be observed by vibration of the brake pedal and noise. You
should never expect the ABS to reduce the braking distance under any cir-
cumstances. Braking distances will increase when driving on gravel, recent
snow or on icy and slippery ground.
Brake assist system (BAS)
The brake assist system may reduce the required braking distance. The
brake assist system boosts the braking force if you press the brake pedal
quickly in an emergency. As a result, the braking pressure increases rapidly,
the braking force is multiplied and the braking distance is reduced. This en-
ables the ABS to be activated more quickly and efficiently.
¡Do not lift your foot off the brake pedal! When the brake pedal is released
or when the brake force is reduced, braking assist automatically turns off
the brake servo. Traction control system (ASR) or Traction Control (TC)
In the event of wheelspin, the traction control system ASR or TC reduces the
engine torque to match the amount of grip available. The ASR or TC makes
some situations easier, for example, when starting, accelerating or going
uphill, even in unfavourable road conditions.
Electronic differential lock system (EDL)
EDL is available when driving in straight lines under normal conditions.
When the EDL detects wheelspin, it brakes the spinning wheel and directs
the power to the other driven wheel. To prevent the disc brake of the braked
wheel from overheating, the EDL cuts out automatically if subjected to ex-
cessive loads. The EDL will switch on again automatically when the brake
has cooled down.
WARNING
Driving at high speed on icy, slippery wet ground can result in loss of ve-
hicle control and serious injury to the driver and passengers.
● Adjust your speed and driving style to visibility, road, traffic and
weather conditions. Even though the braking assist systems, ABS, BAS,
EDL, ASR, TC and ESC*, provide more security, do not take unnecessary
risks while driving.
● Braking assist systems can not overcome the laws of physics. Even
with ESC* and other systems, slippery and wet roads will always be dan-
gerous.
● Driving to quickly on wet ground can result in the wheels losing con-
tact with the ground in an effect known as “aquaplaning”. Without ad-
herence, it is impossible to brake, steer or control the vehicle.
● Braking assist systems cannot avoid accidents if, for example, the
driver does not respect safety distances or drives to quickly in difficult
conditions. 

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 ⇒

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.

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.
CAUTION
Failure to heed the warning lamps when they appear may result in faults in
the vehicle. 

Special driving situations

ahead out of range of the laser sensor
Fig. 100 Other vehicles
changing lanes
The City Safety Assist function has physical limits, and has limits deter-
mined by the system itself. In certain circumstances, this may produce reac-
tions from the City Safety Assist system, that are late or unexpected by the
driver. For this reason, always pay due attention and if necessary, intervene. For example, the following driving situations require special attention:
Driving through a bend
When entering or leaving a “long” bend, the vehicle may decelerate when
the laser sensor detects a vehicle travelling in the opposite lane
⇒ Fig. 99 A.
To interrupt the deceleration you can accelerate, turn the steering wheel or
press the clutch.
Narrow vehicles in front
The laser sensor will only detect narrow vehicles in front if they are in the
sensor detection zone ⇒ Fig. 99 B. This applies especially to narrow vehi-
cles such as motorbikes.
Other vehicles changing lanes
Vehicles changing lane in close proximity can cause an unexpected brake
from the City Safety Assist system ⇒ Fig. 100. To interrupt the deceleration
you can accelerate, turn the steering wheel or press the clutch. 

Malfunction in the laser sensor
If the laser sensor operation is impaired, for example due to heavy rain,
spray, snow or dirt, the City Safety Assist system function is temporarily
switched off. On the instrument panel display the control lamp  flashes.
When the fault in the laser sensor has been rectified, the City Safety Assist
system function automatically becomes available. The control lamp 
switches off.
The following conditions could prevent the City Safety Assist system from
functioning:
● Tight bends.
● Accelerator pressed all the way down to the floor.
● If the City Safety Assist system is switched off or there is a fault
⇒ page 156.
● If the laser sensor is dirty, covered or overheated ⇒ page 157.
● In the event of snow, heavy rain or dense fog.
● If there are vehicles in front.
● Vehicles changing lanes.
● Vehicles moving in the opposite direction in the same lane.
● Very dirty vehicles with a low degree of reflection.
● Presence of thick dust. 

WARNING (Continued)
– If you are using a metal fuel canister, the nozzle must always touch
the canister while it is being filled to avoid static electricity.
– Follow the legal requirements for the use, storage and transport of
spare fuel canisters.
– Insure that the fuel container complies with manufacturing stand-
ards, for example, ANSI or ASTM F852-86.
CAUTION
● Always remove any fuel spilled anywhere on the vehicle to avoid dam-
age to the wheel housing, the tyre and vehicle paintwork.
● Refuelling a petrol engine with diesel can cause serious engine and fuel
system damage; the resulting malfunctions are not covered by the SEAT
warranty. If you refuel with the wrong type of fuel, never start the engine.
This applies to even the smallest amount of the wrong fuel. You should ob-
tain professional assistance. With the engine running, the composition of
the wrong fuel could significantly damage the fuel system and the engine
itself.
