Automatic gearbox malfunction
Back-up programme
When automatic gearbox warning and control lamps light up on the instru-
ment panel, there may be a system malfunction ⇒ page 124. In the event of
some faults the automatic gearbox functions using a backup programme.
When the backup programme is activated, it is possible to drive the vehicle,
however, at low speeds and within a selected range of gears.
With the manual gearbox, in some cases it is not possible to drive with all
the gears.
In all cases the automatic gearbox must be checked at a specialised work-
shop.
Automatic gearbox overheating
The automatic gearbox can overheat with a prolonged start up, or when
stopping and starting continuously. This overheating is displayed with a
warning lamp  in the instrument panel. Additionally, an audible warning
can be heard. Stop and let the gearbox cool ⇒ 
.
The vehicle moves forward or back despite having selected a gear range
When the vehicle does not move in the required direction, the system may
not have the gear range correctly engaged. Press the brake pedal and en-
gage the gear range again. If the vehicle still does not move in the required
direction, there is a system malfunction. Seek specialist assistance and
have the system checked.
CAUTION
● When the gearbox is displayed as overheating for the first time, the vehi-
cle must be parked safely or must be driven at a speed of more than 20 km/
h (12 mph).
● When the warning lamp lights up and the audible warning is sounded,
the vehicle must be parked safely and the engine switched off. Let the gear-
box cool down.
● To prevent damage to the gearbox, driving must only be continued when
the warning lamps are no longer lit up. While the gearbox is overheated,
starting up and driving at walking speed should be avoided. 
Recommended gear display
In some vehicles, the recommended gear for reducing fuel consumption is
displayed on the instrument panel display:

Braking, stopping and parking
Introduction
The assisted braking systems are the electronic distribution of the brake
force (EBV), the anti-lock brake system (ABS), the brake assist system (BAS),
the electronic differential lock (EDL), the traction control (TC), the traction
control system (ASR) and the electronic stability control (ESC*).
Additional information and warnings:
● Wheels and tyres ⇒ page 210
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
Driving with worn brake pads or a faulty brake system may lead to seri-
ous accident.
● If you believe the brake pads to be worn or the brake system to be
faulty, immediately refer to a specialised workshop to check the brake
pads and replace the worn brake pads.
WARNING
Careless parking can cause serious injury.
● Never remove the key from the ignition if the vehicle is in motion. The
steering lock may engage and locked the steering wheel making the vehi-
cle impossible to control.
● 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).
WARNING (Continued)
● Always apply the handbrake when you leave your vehicle and when
you park.
● Never leave children or disabled people alone in the vehicle. They
could release the electronic parking brake, activate the selector lever or
gear stick and start the vehicle moving. This could result in serious acci-
dent.
● Always take all the keys with you whenever you leave the vehicle. The
engine could accidentally be started and electrical equipment such as
the windows could accidentally be operated resulting in serious injury.
● Never leave children or disabled people alone in the vehicle. They
could be trapped in the vehicle in an emergency and will not be able to
get themselves to safety. For example, depending on the time of the
year, temperatures inside a locked and closed vehicle can be extremely
high or extremely low resulting in serious injuries and illness or even
death, particularly for young children.
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. 

136Starting, changing gears, parking
WARNING (Continued)
your speed and drive carefully to a Specialised workshop close by to
check the brake system. During the following journey, avoid sudden brak-
ing and manoeuvres.
● If the ABS warning lamp  does not go out or if it lights while driv-
ing, the ABS is malfunctioning. The vehicle can only be stopped using
normal braking without ABS. The protection provided by the ABS is not
available. Visit a specialised workshop as soon as possible.
CAUTION
Failure to heed the warning lamps when they appear may result in faults in
the vehicle. 
Handbrake
Fig. 90 Between the
front seats: Handbrake Using the handbrake
●
Pull firmly in an upwards direction on the handbrake lever while press-
ing the button.
● The handbrake is applied when the control lamp  lights up on the in-
strument panel ⇒ page 135 when the ignition is switched on.
Releasing the handbrake
● Pull gently in an upwards direction on the handbrake lever and press the
lock button ⇒ Fig. 90 (arrow).
● Move the handbrake lever downwards keeping the lock button pressed.
WARNING
The incorrect use of the handbrake may result in a serious accident.
● Never use the handbrake to brake the vehicle except in an emergency.
The braking distance is considerably longer, because braking is only ap-
plied to the rear wheels. Always use the foot brake.
● Never drive with the handbrake gently applied. This can overheat the
brake, affecting the brakes system. This also causes premature wear on
the rear brake pads.
● Never accelerate from the engine compartment with the engine run-
ning and a gear engaged. The vehicle could move, even if the handbrake
is applied.
Note
If the vehicle moves at a speed superior to 6 km/h (4 mph) with the hand-
brake applied, an audible warning is sounded. 
Parking
When parking your vehicle, all legal requirements should be observed. 

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.

recommends the use of brake fluid in accordance with the VW 501 14
standard. If this brake fluid is not available or another brake fluid is used for
different reasons, use a brake fluid that complies with the United States
standard FMVSS 116 DOT 4 or the German standard DIN ISO 4925 CLASS 4
⇒ 
.
Brake fluids conforming to the standard VW 501 14, fulfil the American re-
quirements of the FMVSS 116 DOT 4 standard and the German
DIN ISO 4925 CLASS 4 standard. However, fluids that comply with the Amer-
ican FMVSS 116 DOT 4 standard or the German DIN ISO 4925 CLASS 4
standard do not necessarily comply with the VW 501 14 standard. Always
check the information on the brake fluid container and ensure that you are
using suitable brake fluid.
A suitable brake fluid can be obtained from SEAT dealerships.
Brake fluid level
The level of the brake fluid should always be between the MIN and MAX
marks, or above the MIN mark ⇒ 
.
It is not always possible to check the level of the brake fluid, as in some
models the engine components make it difficult to see the brake fluid reser-
voir. If you cannot read the exact brake fluid level, consult a specialist.
The brake fluid level drops slightly when the vehicle is being used due to
wear of the brake pads and the automatic readjustment of the brake.
Changing the brake fluid
The brake fluid should be changed in accordance with the instructions giv-
en in the Maintenance Programme. Have the brake fluid changed by a Spe-
cialised workshop. SEAT recommends visiting a Technical Service. This
means that only brake fluid complying with the required specifications will
be used.
WARNING
If the brake fluid level is low or unsuitable/old brake fluid is used, the
brake system may fail or braking power will be reduced.
● Check the brake system and the brake fluid level regularly!
● The brake fluid should be changed regularly in accordance with the
instructions given in the Maintenance Programme.
● When the brake fluid is used and brakes are subjected to extreme
braking forces, bubbles of vapour form in the brake system. These bub-
bles of water vapour can significantly reduce braking power, notably in-
creasing braking distance, and could even result in the total failure of the
brake system.
● Always ensure that you use suitable brake fluid. Only used brake fluid
that conforms to the VW 501 14 standard, FMVSS 116 DOT 4 standard or
even the DIN ISO 4925 CLASS 4 standard. Other types of brake fluid
could affect brake operation and reduce braking power. Do not use a
brake fluid if the container does not specify compliance with the
VW 501 14, FMVSS 116 DOT 4 or DIN ISO 4925 CLASS 4 standards.
● The replacement brake fluid must be new.
WARNING
Brake fluid is poisonous.
● To reduce the risk of poisoning, do not keep brake fluid in drinks bot-
tles/containers or similar. Other people could drink from these recipients
even if the contents are clearly marked.
● Always keep brake fluid in the original container; keep it correctly
sealed and out of reach of children.
CAUTION
Brake fluid could damage the paintwork. Wipe off any brake fluid from the
paintwork immediately. 

146Starting, changing gears, parking
Unnecessary short journeys should be avoided. Try to combine trips.
The vehicle uses more fuel in winter than in summer, even when other con-
ditions are the same.
“Warming” the engine is not only forbidden in some countries, but in prac-
tice it is technically superfluous as it is a waste of fuel.
Adjusting type pressures.
Having the correct pressure in your tyres helps to reduce rolling resistance
and, as a result reduces fuel consumption. Increasing the tyre pressure
slightly (+ 0.2 bar / + 3 psi / + 200 kPa) can help to save fuel.
When you buy new tyres, make sure they are optimised for minimum rolling
resistance.
Use low friction engine oil
The use of low viscosity totally synthetic oils, known as low friction engine
oil, help to reduce fuel consumption. Low friction engine oils reduce the re-
sistance caused by friction in the engine, they flow around the engine more
quickly and efficiently, particularly in cold starts. The effect is particularly
noticeable in vehicles frequently used for short journeys.
Always check the engine oil level and observe service intervals (engine oil
change intervals).
When purchasing engine oil, always observe legal requirements and ensure
that the oil is approved by SEAT.
Avoid carrying unnecessary loads
The lighter the vehicle, the more economical and ecological the driving
style. For example, an additional weight of 100 kg will increase fuel con-
sumption up to 0.3 ltr/100 km.
Remove any unnecessary objects or loads from the vehicle. Remove optional equipment and unnecessary accessories
The more aerodynamic the vehicle, the lower the fuel consumption. Option-
al equipment and accessories (such as roof racks or bike carriers) reduce
the aerodynamic benefits of the vehicle.
Therefore, we recommend you remove all optional and unnecessary equip-
ment and racks, especially if you intend to drive at high speeds.

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.

Dust and pollen filter
The dust and pollen filter with its activated charcoal cartridge serves as a
barrier against impurities in the interior ambient air.
For the air conditioner to work with maximum efficiency, the dust and pollen
filter must be replaced at the intervals specified in the Maintenance Pro-
gramme.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the filter must be changed more frequently than sta-
ted in the Service Schedule.
Additional information and warnings:

WARNING
Reduced visibility through the windows increases the risk of serious acci-
dents.
● Ensure that all windows are free of ice and snow and that they are not
fogged up preventing a clear view of everything outside.
WARNING (Continued)
● The maximum heat output required to defrost windows as quickly as
possible is only available when the engine has reached its normal run-
ning temperature. Only drive when you have good visibility.
● Always ensure that you use the heating system, ventilation, air condi-
tioner and the heated rear window to maintain good visibility.
● Never leave the air recirculation on for a long period of time. If the
cooling system mode is switched off and air recirculation mode switched
on, the windows can mist over very quickly, considerably limiting visibili-
ty.
● Switch air recirculation mode off when it is not required.
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
● Never leave the air fan turned off or use the air recirculation for long
periods of time; the air inside the interior will not be refreshed.
CAUTION
● Switch the air conditioner off if you think it may be broken. This will
avoid additional damage. Have the air conditioner checked by a Specialised
workshop.
● Repairs to the climate air conditioner specialist knowledge and special
tools. SEAT recommends visiting a Technical Service. 
