Driving
WARNING
The components of the exhaust system reach
ver y
high temperatures. This could cause a
fire and considerable damage.
● 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, or spilled fuel). 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. Information on the brakes
For the first 200 to 300 km (100 to 200
mi
l
e

s), new brake pads have not yet reached
their maximum braking capacity, and need to
be “run in” first ››› . The slightly reduced
br ak in

g effect can be compensated for by in-
creasing pressure on the brake pedal. While
running in, the full braking distance or emer- gency braking distance is larger
then when
the brake p
ads have been run in. While run-
ning 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 conditions 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, af-
ter crossing areas of water, in heavy rainfall
or even after washing the car, 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 possi-
ble by braking gently several times. Only do
this without endangering vehicles behind
you or any other road users ››› .
A l a
y

er of salt on the discs and brake pads
will reduce the effectiveness of the brakes
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
v

ehicle remains parked for considera-
ble 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 onthe brake pads. If the brakes are not used fre-
quently, or if ru

st has formed on the discs,
SEAT recommends cleaning the pads and
discs by braking firmly a few times at a mod-
erately high speed. Only do this without en-
dangering vehicles behind you or any other
road users ››› .
F au
lt

s in the brake system
During braking, if you notice that the vehicle
does not react as usual (that the braking dis-
tance has increased suddenly) it may be pos-
sible that there is a fault in the braking sys-
tem. The  warning lamp lights up and a
text message displayed. 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 stopping
distances.
Brake servo
The brake servo only operates when the en-
gine is running and the pressure applied by
the driver on the brake pedal increases.
If the brake servo does not operate or the ve-
hicle 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 ››› .

Operation
WARNING
New brake pads do not brake to full efficien-
cy.
● For the fir
st 320 km (200 miles), new brake
pad
s 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.
● To avoid losing control of the vehicle and
caus
ing serious accidents, always take great
care when driving with new brake pads.
● When running in new brake pads, always
res
pect the safety distances between you and
other vehicles and do not cause situations re-
quiring extreme braking performance. WARNING
When brakes overheat, braking is less effi-
cient and br

aking distances increase.
● When driving on slopes, brakes can be
overlo
aded and overheat quickly.
● Reduce speed or change down a gear when
faced w
ith 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
coul
d restrict the airflow to the brakes and
cause them to overheat. WARNING
Wet, frozen or salt-covered brakes take lon-
ger t o en

gage and this increases braking dis-
tances.
● Test the brakes carefully.
● Dry the brakes, free them of ice and salt by
brakin
g gently several times, when weather,
road and traffic conditions permit. WARNING
Driving without the brake servo may signifi-
cantly inc

rease the braking distance and re-
sult 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
vehicl
e 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. CAUTION
● Never m ak

e 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 signifi-
cantly reduce braking power, increase brak-
ing distance or even result in the total failure
of the brake system.
● Reduce speed or change down a gear when
faced w
ith steep and long slopes. This allows
you to use the engine braking effect and to reduce the strain on the brake system. Other-
wi
se, the br

akes may overheat and fail. Only
use the brakes to reduce speed or to stop. Note
When checking the front brake pads, take the
time t o al

so check the rear brake pads. The
thickness of the brake pads should be
checked visually and regularly, by looking
through the openings in the wheel rims or
from underneath the vehicle. If necessary, re-
move the wheels to check them thoroughly.

nical service. Gearbox

traffic conditions so permit. WARNING
Do not allow the brakes to “rub” for a pro-
long ed period of

time, or brake frequently or

● The use of water-soluble paints.
Economical and environmentally
friendly drivin
g Fuel consumption, environmental impact and
engine, br
ak

e and tyre wear depend largely
on three factors:
● Personal driving style.
● Conditions of use (weather, road surface).
● Technical requirements.
Savin g

s of up to 25% in fuel consumption
are possible with an appropriate driving style
and the adoption of certain simple tips.
Changing gear early
General instructions: The highest gear is al-
ways the most economical. As a guideline,
for the majority of vehicles: at a speed of
30 km/h (19 mph), drive in third gear, at
40 km/h (25 mph) in fourth gear and at
50 km/h (31 mph) in fifth gear.
In addition, “skipping” gears when shifting
up helps to save fuel, weather and traffic
conditions permitting.

Driver assistance systems
● Do not s
t
op in the water, use reverse gear
or switch off the engine.
● Oncoming traffic will cause waves which
raise the l
evel of the water, making it difficult
to cross the water.
The Start/Stop system must be deactivated
when driving through flooded areas WARNING
When driving through water, mud, melted
sno w

, etc., please remember that due to
damp or frozen brake discs and shoes in win-
ter, the braking effect may be delayed, there-
fore the required braking distance is greater.
● “Dry the brakes and remove ice” by braking
caref
ully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process.
● After driving through water, avoid sudden
sharp manoeu
vres. CAUTION
● Drivin g thr

ough flooded areas may severely
damage vehicle components such as the en-
gine, transmission, drive train or electrical
system.
● Never drive through salt water as salt cau-
ses c
orrosion. Always rinse any parts of the
vehicle which have been in contact with salt
water. Driver assistance systems

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. 206 when traction is
insufficient. Always remember to turn on the
ASR once more when the vehicle has traction
again. »

Safety

Operation
Anti-lock system (ABS)
ABS c
an 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 front wheels are turned, the normal ABS is
activated.
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 207.
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.

Driver assistance systems
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. 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
