Driving
The vehicle key has a chip that automatically
di s
ab
les the immobilizer when the key is
placed in the ignition lock.
The electronic immobiliser will be activated
again automatically as soon as you pull the
key out of the ignition lock. For vehicles with
the Keyless Access system, the key has to be
outside the vehicle ››› page 115.
For this reason, the vehicle can only be used
with a genuine SEAT key with the correct
code. Coded keys can be purchased from
your technical service centre ››› page 110.
If an unauthorised key is used, the message
SAFE or Immobiliser active is displayed
on the instrument panel. The vehicle cannot
be started in this case Note
The correct operation of the vehicle is only
guarant eed when origin
al SEAT keys are
used. Braking and parking
Intr oduction The a
ssisted braking systems include the an-
ti-loc k
braking system (ABS), the brake assist
system (BAS), the electronic differential lock
(EDL), the traction control system (ASR) and
the electronic stability control (ESC). WARNING
Driving with worn brake pads or a faulty
brak e sy
stem may lead to serious accident.
● If lights, alone or accompanied by a
warnin
g message on the instrument panel
display, please go immediately to a special-
ised workshop to check the brake pads and to
replace them if they are worn. WARNING
Careless parking can cause serious injury.
● Never remove the key from the ignition if
the v ehic
le is in motion. The steering lock
may engage and lock the steering wheel mak-
ing the vehicle impossible to control.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
flammable materials (such as wood, leaves,
dried grass, spilled fuel, etc.).
● Always apply the electronic parking brake
when you l
eave your vehicle and when you
park.
● Never leave children or disabled people
alone in the v
ehicle. They could release the
electronic parking brake, activate the selec-
tor lever or gear stick and start the vehicle
moving. This could result in a serious acci-
dent.
● Always take all the keys with you whenever
you le
ave the vehicle. The engine could acci-
dentally be started and electrical equipment
such as the windows could accidentally be
operated resulting in serious injury. ●
Never l e
ave children or disabled people
alone in the car. They could be trapped in the
car in an emergency and will not be able to
get themselves to safety. For example, de-
pending on the time of the year, tempera-
tures 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
● Spec i
al care should be taken when parking
in areas with high kerbs or fixed barriers. Ob-
jects protruding from the ground may dam-
age the bumper or other parts of the vehicle
during manoeuvres. To avoid damage, stop
before the wheels touch the barrier or kerb.
● Special attention is required when driving
through entranc
es, over ramps, kerbs or oth-
er objects. The vehicle underbody, bumpers,
mudguards and running gear, and the engine
and exhaust system could be damaged as
you drive over these objects. Control and warning lamps

Driver assistance systems
Br ak
in
g and stability systems
Brake assist systems The brake assist systems ESC, ABS, BAS, ASR
and EDL on
ly
operate when the ignition is
switched on. They contribute significantly to
increasing active safety.
Electronic Stability Control (ESC)
ESC reduces the risk of skidding and increa-
ses 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 ve-
hicle by braking individual wheels or by re-
ducing 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 cov-
ered by water, mud or snow then ESC will not
provide assistance in the same way as on dry
ground. If the vehicle loses its grip on the
ground and moves on a film of water (“aqua-
planing”), the ESC will not be able to assist the driver to control the vehicle as the loss of
adher
enc
e with the road surface will prevent-
ing braking and steering. If the vehicle is
driven through series of bends at high
speed, the ESC will not always be as effec-
tive: the vehicle reaction to aggressive driv-
ing is not the same as at reduced speeds.
When driving with a trailer, ESC does not pro-
vide the same amount of vehicle control as
without a trailer.
Adjust your speed and driving style to road,
traffic and weather 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 at-
tention creates an inevitable situation. Other-
wise, ESC assists in maintaining vehicle con-
trol in extreme situations and uses the move-
ments of the steering made by the driver to
maintain the vehicle moving 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 in-
corporated into the ESC. The ESC is always
on. The ESC should only be turned off using
the ASR button ›››
Fig. 205 when traction is
insufficient. Always remember to turn on the
ASR once more when the vehicle has traction
again. Anti-lock system (ABS)
ABS can pr
event the wheels from locking dur-
ing 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
remov
e your foot from the brake pedal or re-
duce braking force!
● Do not “pump” the brake pedal, or reduce
brakin
g force!
● Maintain vehicle direction when braking
ful
ly.
● When the brake pedal is released or when
the brake f
orce 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 dis-
tance under any circumstances. This distance
will increase when driving on gravel, recent
snow or on icy and slippery ground.
When driving on loose ground, the all-terrain
configuration of the ABS is automatically
turned on. When ABS is activated, the front
wheels may lock briefly. This shortens the
braking distance in off-road situations as the
wheels are prevented from digging into loose
surfaces. All-terrain ABS only intervenes
when driving in a straight line. When the »
203

Operation
front wheels are turned, the normal ABS is
activ at
ed.
Br
ake assist system (BAS)
The brake assist system may reduce the re-
quired 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 rap-
idly, the braking force is multiplied and the
braking distance is reduced. This enables the
ABS to be activated more quickly and effec-
tively.
¡Do not lift your foot off the brake pedal!
When the brake pedal is released or when
the brake force is reduced, braking assist au-
tomatically turns off the brake servo.
Traction control when accelerating (ASR)
In the event of wheelspin, the traction control
system reduces the engine torque to match
the amount of grip available. The ASR makes
some situations easier, for example, when
starting, accelerating or going uphill, even in
unfavourable road conditions.
The ASR can be switched on or off manually
››› page 205.
Electronic differential lock system (EDS)
EDL is available when driving in straight lines
under normal conditions. When the EDL de-
tects wheelspin, it brakes the spinning wheel and directs the power to the other drive
wheels. T
o prevent the disc brake of the
braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive
loads. The EDL will switch on again automati-
cally when the brake has cooled down.
Electronic drive torque management (XDS)
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected. WARNING
Driving at high speed on icy, slippery wet
grou nd c
an result in loss of vehicle control
and serious injury to the driver and passen-
gers.
● Adjust your speed and driving style to visi-
bility
, road, traffic and weather conditions.
Even though the brake assist systems, ABS,
BAS, EDL, ASR and ESC, provide more securi-
ty, do not take unnecessary risks while driv-
ing.
● Brake assist systems can not overcome the
law
s of physics. Even with ESC and other sys-
tems, slippery and wet roads will always be
dangerous.
● Driving to quickly on wet ground can result
in the wheels lo
sing contact with the ground
in an effect known as “aquaplaning”. Without
adherence, it is impossible to brake, steer or
control the vehicle.
● Brake assist systems cannot avoid acci-
dents if
, for example, the driver does not re-
spect safety distances or drives to quickly in
difficult conditions.
● Even though brake assist systems are ex-
tremely eff
ective and help control the vehicle
in difficult situations, remember that the ve-
hicle stability depends on tyre grip.
● When accelerating on a slippery surface,
for ex
ample on ice or snow, press the acceler-
ator carefully. The wheels can still slip even
with brake assist systems resulting in loss of
vehicle control. 204

WARNING
The effectiveness of the ESC can be consider-
ably r
educed if other components and sys-
tems affecting driving dynamics are not main-
tained 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 opera-
tion of the ABS, BAS, ASL EDL and ESC.
● Changes to the vehicle suspension or using
unap
proved wheel/tyre combinations can af-
fect operation of the ABS, BAS, ASL EDL and
ESC, as well as their effectiveness.
● Likewise, the effectiveness of ESC depends
on the use of s
uitable tyres ››› page 284. Note
● To en s
ure that the ESC and ASR work prop-
erly, all four wheels must be fitted with iden-
tical tyres. Any differences in the rolling radi-
us of the tyres can cause the system to re-
duce engine power when this is not desired.
● If a malfunction should occur in the ABS,
the ESC, EDL and ASR w
ill also be out of ac-
tion.
● Noises may be heard while any of the
above sy
stems are operating. Switching ASR on and off

Intr oduction The tyre monitor indicator monitors the tyre
pr
e
s
sure of each wheel during driving using
the ABS sensors. The ABS sensors monitor
the tyre tread perimeter and vibrations of
each tyre. The tyre monitor indicator warns
the driver if it detects a considerable drop in
tyre pressure of one or several tyres while driving. Loss of tyre pressure will be indica-
ted by
the indicator as well as an audible
warning and sometimes a text message on
the dash panel display. When you open the
driver door, you will find a label indicating
the tyre pressure recommended by the manu-
facturer for the maximum vehicle load for
each tyre approved for the vehicle in ques-
tion. By pressing the adjustment button on
the tyre monitoring indicator, you may
change the reference pressure for the tyres
so that the tyre pressure coincides with ac-
tual pressure ››› page 233.
Suitable use of the adjustment button
››› page 233. WARNING
Unsuitable handling of the wheels and tyres
ma y
lead to sudden tyre pressure losses, to
tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure
they are m
aintained at the pressures indica-
ted. If the tyre pressure is too low, the tyres
could overheat, resulting in tread detachment
or even burst tyres.
● Tyre pressure should be that indicated on
the label when the ty
res are cold at all times

●
If the w arnin
g lamp lights up, stop im-
mediately and check the tyres.
● If the tyres are inflated at different pres-
sure
s or if a tyre pressure is too low, this will
increase tyre wear, negatively affecting vehi-
cle stability and increasing braking distan-
ces.
● If tyres are inflated at different pressures or
a tyre pr
essure is too low, a tyre may be dam-
aged and burst resulting in a loss of control
of the vehicle.
● The driver is responsible for ensuring that
all
of the vehicle tyres are correctly inflated
to the right pressure. The recommended tyre
pressure is indicated on the label ››› Fig. 251.
● The tyre monitoring system can only oper-
ate corr
ectly if all of the tyres are inflated to
the correct pressure when cold.
● Driving with tyres at the wrong pressure
can dam
age them and result in an accident.
Ensure that the tyre pressures of all the tyres
correspond to the vehicle load.
● Before starting a journey, always inflate
tyre
s to the correct pressure.
● If tyre pressure is too low then the tyre is
subj
ect to greater forces and it may be heated
to such an extent that the tread can rupture
and the tyre will burst.
● With an overloaded vehicle at high speed,
the tyre
s can overheat and burst resulting in
a loss of vehicle control.
● Tyre pressures which are too high or too
low reduc
e the useful life of the tyre, affect-
ing vehicle performance. ●
If a ty r

● If the wheels on an axle are subject to a
heavier lo
ad (e.g. when towing a trailer).
● The vehicle is fitted with snow chains
● The wheel on one axle is changed
There ma
y be a delay in the reaction of the
tyre monitoring indicator or it may not in-
dicate anything under certain circumstances
(e.g. sports driving, snow-covered or un-
paved roads).
Adaptation of the tyre monitoring indicator
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 228 button on the
tyre monitoring indicator must be kept press-
ed down, with the ignition on, until an audi-
ble warning is heard. Do the same, for exam-
ple, when the front and rear wheels are swap-
ped ››› Fig. 250.
If the wheels are subjected to an excessive
load (towing a trailer, heavy load), the tyre
pressure must be increased to the maximum
recommended pressure ››› page 284. Press
the tyre monitoring indicator button to con-
firm the new pressure value. Note
An incorrect warning may be given when
sno w c
hains are in use because the chains in-
crease the tread of the wheel. 233
