themselv
es 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.
● Never remove the key from the ignition if
the vehic
le is in motion. The steering may
lock and it will not be possible to turn the
steering wheel. CAUTION
● An attempt t

o start the engine while driving
or starting the engine immediately after turn-
ing it off can cause damage to the engine or
starter motor.
● When the engine is cold, avoid high revs
and heavy ac
celeration and do not make the
engine work hard.
● Do not push or tow start the engine. Un-
burnt f
uel could damage the catalytic con-
verter. For the sake of the environment
Do not warm the engine at idle speed; start
drivin g immedi

ately if the visibility is OK.
This helps the engine reach operating tem-
perature faster and reduces emissions. Note
● If the k ey

is left in the ignition lock with the
engine off for long periods, the vehicle bat-
tery will run flat.
● For automatic gearbox vehicles, the key can
only be r
emoved from the ignition lock if the
gear selector lever is in position N. In this
case, press and release the selector lever
locking button.
● Electrical devices with a high power con-
sumption are sw
itched off temporarily when
the engine starts.
● When the engine is started cold, there may
be stron
g vibrations for a few moments for
technical reasons. This is quite normal, and
no cause for concern.
● Natural gas engines always start up with
petrol, a
s a certain operating temperature is
required for running with gas. Once the re-
quired operating temperature is reached, the
engine will change to operate with natural
gas. Stopping the engine

Never switch off the engine while the vehicle
is mo

ving. You may lose control of the vehicle
and there is a risk of serious accident.
● The airbags and belt tensioners do not
work when the ignition i
s switched off.
● The brake servo does not work with the en-
gine off. T
o stop, the brake pedal must be
pressed with more force.
● As the power steering does not work if the
engine is
not running, you will need more
strength to steer than normally.
● If the key is removed from the ignition, the

to steer the vehicle. 136

Driving
wheels lock this could result in loss of vehicle
contr
o
l! If possible, reduce your speed and
drive carefully to a specialised workshop
close by to check the brake system. During
the following journey, avoid sudden braking
and manoeuvres.
● If the ABS warning lamp  does not
go out
or if it lights while driving, the ABS is mal-
functioning. The vehicle can only be stopped
using normal braking without ABS. The pro-
tection provided by the ABS is not available.
Visit a specialised workshop as soon as pos-
sible. CAUTION
Failure to heed the warning lamps when they
appe ar m

ay result in faults in the vehicle. Brake assist systems
The assisted braking systems ESC*, ABS,
EB
V
, B

AS, ASR, TC and EDL only 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 vehicle by braking individual wheels or
by reducing the engine torque.
The ESC* has limits. It is important to realise
that ESC* is also subject to the laws of phys-
ics. ESC* will not be able to deal with all sit-
uations with which drivers may be faced. For
example, if the road surface changes sudden-
ly 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 help
the driver control the vehicle due to the loss
of adherence with the road surface 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.
Adjust your speed and driving style to suit
visibility, and weather, road and traffic condi-
tions. ESC* cannot push the limits of the laws
of physics; improve the transmission availa-
ble or maintain the vehicle on the road if a
lack of driver attention creates an inevitable
situation. Otherwise, ESC* assists in main-
taining vehicle control in extreme situations and uses the movements of the steering
made b
y 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 sys-
tem cannot provide assistance.
The ABS, BAS, ASR and EDL systems are in-
corporated into the ESC*. The ESC* is always
on 1)
.
Anti-lock system (ABS)
ABS can prevent 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 »1)

Safety

Operation
expect the ABS to reduce the braking dis-
t anc
e u
nder any circumstances. This distance
will increase when driving on gravel, recent
snow or on icy or slippery ground.
Brake 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 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 go-
ing uphill, even in unfavourable road condi-
tions. Electronic differential lock (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 one. To
prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The EDL
will switch on again automatically when the
brake has cooled down. WARNING
Driving at high speed on icy, slippery or 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
systems, 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
difficu
lt

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 consid-
erab ly

reduced 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, ASR TC, EDL and ESC*.
● Changes to the vehicle suspension or using
unap
proved wheel/tyre combinations can af-
fect operation of the ABS, BAS, ASR, TC, EDL
and ESC* and their effectiveness.
● Likewise, the effectiveness of ESC* de-

Driving
If the brake servo does not operate or the ve-
hic l
e mu
st 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 ››› .
WARNING
New brake pads do not brake to full efficien-
cy.
● For the fir

st 320 km, new brake pads have
not y
et reached their maximum braking ca-
pacity, 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-s t

andard or damaged front spoilers
could restrict the airflow to the brakes and
cause them to overheat. WARNING
Wet, frozen or salt-covered brakes take lon-
g er 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 visibility,
weather, and road and traffic conditions per-
mit. 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 br
ak

e 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-
wise, 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
c hec k

ed, and have the rear pads checked al-
so. 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.

mediately preceding the current gear and at
an engine speed that is not excessive ››› .
At high s
peed

s, or high engine speeds, skip-
ping one or various gears when shifting

and the clutch released. ●
Never en g

age the reverse gear when a vehi-
cle is moving forward. WARNING
As a consequence of shifting down a gear in-

Operation
The City Safety Assist function is limited by
the l a
w
s of physics and by the nature of the
system itself. For this reason, this may pro-
duce reactions from the City Safety Assist
system in certain circumstances that are late
or unexpected by the driver. For this reason,
always pay due attention and if necessary, in-
tervene.
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 adjoining
lane ››› Fig. 156 A. To interrupt deceleration
you can accelerate, turn the steering wheel or
press the clutch.
Narrow vehicles in front
The laser sensor will only detect narrow vehi-
cles in front if they are in the sensor detec-
tion zone ››› Fig. 156 B. This applies especial-
ly to narrow vehicles such as motorbikes.
Other vehicles changing lanes
Vehicles moving into your lane in close prox-
imity can cause unexpected braking from the
City Safety Assist system ›››
Fig. 157. To inter-
rupt deceleration you can accelerate, turn the
steering wheel or press the clutch. Possible malfunction to the laser sensor
If the la
ser sensor operation function is im-
paired, for example due to heavy rain, mist,
snow or dirt, the City Safety Assist system
function is temporarily disconnected. On the
instrument panel display the control lamp 
flashes.
When the malfunction in the laser sensor has
been rectified, the availability of the City
Safety Assist system function is automatically
restored. 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 C

ity Safety Assist system is switched
off or there i
s a fault ››› page 157.
● If the laser sensor is dirty, covered or over-
heated ›

›› page 158.
● In the event of snow, heavy rain or dense
fog.
● If ther

e are vehicles in front.
● Vehicles changing lanes.
● Vehicles moving in the opposite direction
in the same lane.
● V

ery dirty vehicles with a low degree of re-
flection.
● Pr e

sence of thick dust. Hill driving assistant*
Operation This function is only included in vehicles with
ESC.
The hi l

l driving assistant helps the driver to
move off and upward on a hill when the vehi-
cle is stationary.
The system maintains brake pressure for ap-
proximately two seconds after the driver
takes his foot off the brake pedal to prevent
the vehicle from lurching backward when it is
started. During these 2 seconds, the driver
has enough time to release the clutch pedal
and accelerate without the vehicle moving
and without having to use the handbrake,
making start-up easier, more comfortable
and safer.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● doors closed,
● vehicle completely stationary,
● engine running and foot on the brake,
● besides having a gear engaged or being in
neutral f

or manual gear change and with the
selector lever at positions S, D or R in vehi-
cles with an automatic gearbox.
This system is also active when reversing up-
hill.

Advice
used in an emergency and with extreme cau-
tion.
Note
For technical reasons, it is not generally pos-
s ib l
e to use the wheels from other vehicles.
In some cases, this may also be true for the
same model of wheel. Please refer to the ve-
hicle documentation or ask at a technical
service. Handling tyres and wheels
Fig. 173
Diagram for changing wheels The tyres of a vehicle are the components
whic
h ar
e s

ubjected to most stress and are
the most underestimated. Tyres are very im-
portant, as the support offered by their nar-
row surface is the only point of contact be-
tween the vehicle and the road. The service life of tyres is dependent on tyre
pres

sure, driving style, the care they receive
and the correct fitting.
The tyres and wheel rims are an essential
part of the vehicle's design. The tyres and
rims approved by SEAT are specially matched
to the characteristics of the vehicle and our
critical to good road holding and safe han-
dling.
Avoiding damage to tyres and wheels
● If you have to drive over a kerb or similar
obs
tacle, drive very slowly and as near as
possible at a right angle to the kerb.
● Inspect the tyres regularly for damage
(punct
ures, cuts, cracks, dents).
● Remove any foreign bodies found on the
outside of the ty
re tread and ensure that they
have not passed through the wall of the tyre
››› page 204.
● In addition, the instructions for tyre control
syst
ems should always be observed.
● Replace damaged or worn tyres as soon as
poss
ible ››› page 204.
● Regularly check tyres for non-visible dam-
age ››

› page 204.
● Never exceed the maximum permitted
speed or loa
ds specified for the type of tyre
fitted on your vehicle ››› page 207.
● Do not allow tyres (including the spare
wheel) to come int
o contact with aggressive substances, grease, oil, fuel or brake fluid
›››
.
● Lost valve caps should be replaced imme-
di at
ely

.
Tyres with directional tread pattern
Tyres with directional tread pattern have
been designed to operate best when rotating
in only one direction. An arrow on the tyre
sidewall indicates the direction of rotation on
tyres with directional tread ››› page 207. Al-
ways observe the direction of rotation indica-
ted when mounting the wheel. This guaran-
tees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
If the tyre is mounted in the opposite direc-
tion of rotation, drive with extreme caution,
as the tyre is no longer being used correctly.
This is of particular importance when the
road surface is wet. Change the tyre as soon
as possible or remount it with the correct di-
rection of rotation.
Interchanging tyres
To ensure that the wear is equal on all tyres
the wheels should be changed round from
time to time according to the system
››› Fig. 173. The useful life of all the tyres will
then be about the same time.
SEAT recommends you take the vehicle to a
specialised workshop to have the tyres
changed.

Wheels and tyres
Tyres over 6 years old
T y
r
es are subject to an ageing process as a
result of physical and chemical processes.
This may affect their performance. Tyres
which are stored for long periods of time
without being used, harden and become
more fragile than tyres which are in constant
use.
SEAT recommends that tyres over six years
old are replaced with new tyres. This also ap-
plies to tyres (including the spare wheel)
which appear to be in perfect condition on
the outside and which have a tread depth
within the values stipulated by the Law ››› .
The d at
e of

manufacture, part of the tyre
identification number (TIN), indicates the age
of the tyre ( ) ››› page 207.
Storing tyres
Mark tyres when you remove them to indicate
the direction of rotation (left, right, forwards,
backwards). This ensures you will be able to
mount them correctly when you replace
them. When removed, the wheels and/or
tyres should be stored in a cool, dry and pref-
erably dark location. Do not place tyres
mounted on the wheel in a vertical position.
Protect tyres not mounted on wheels from
dirt by storing them in suitable bags and
standing them on the ground on their tread. WARNING
Aggressive fluids or substances could result
in v i

sible or invisible damage with the conse-
quent risks.
● Always ensure that tyres do not come into
contact
with chemical products, oil, grease,
fuel, brake fluid or other aggressive substan-
ces. WARNING
Old tyres, even if they have never been used,
ma y

lose air or burst unexpectedly while driv-
ing, resulting in serious accident or damage.
● If tyres are over six years old, they should
only be u
sed in an emergency and with ex-
treme caution. For the sake of the environment
Old tyres must be disposed of by qualified
personnel ac

cording to the laws in the coun-
try concerned. Wheels
The design of wheel bolts is matched to the
rims. If
diff
er

ent rims are fitted, the correct
wheel bolts with the right length and correct-
ly shaped bolt heads must be used. This en-
sures that wheels are fitted securely and that
the brake system functions correctly
››› page 72. For technical reasons, it is not generally pos-
sibl

e to use the wheels from other vehicles.
In some cases, this may also be true for the
same model of wheel.
The tyres and rims approved by SEAT are spe-
cially matched to the characteristics of the
vehicle and are critical to good road holding
and safe handling.
Wheel bolts
Wheel bolts must be tightened to the correct
torque ››› page 72.
Beadlock wheel rims
Beadlock wheel rims have various compo-
nents. These are joined together by special
bolts using a special procedure. This ensures
good performance, a better seal, improved
safety and wheel run out. Therefore, worn
rims should always be replaced and must on-
ly be repaired in a specialised workshop.
SEAT recommends visiting a technical service
››› .
Wheel rims
w

ith bolted trims
Wheel rims may be fitted with interchangea-
ble trim parts which are attached to the rim
using self-locking bolts. Worn trims should
only be replaced at a specialised workshop.

Wheels and tyres
Foreign bodies in the tyre
● Do not remove foreign bodies if they have
penetr at
ed thr
ough the tyre wall!
● You should obtain professional assistance
immediately
.
Tyre wear
The wear of tyres depends on a number of
factors, for example:
● Driving style.
● Unbalanced wheels.
● Running gear settings.
Driving
style: Driving round bends quickly or
sudden acceleration or braking speed accel-
erates tyre wear. When the driving style is
normal, if the tyres wear too quickly, have the
running gear settings checked at a special-
ised workshop.
Wheel run-out: The wheels on new vehicles
are balanced. However, certain circumstan-
ces may lead to imbalance (run-out), which is
detected as vibrations in the steering wheel.
Run-out leads to wear of the steering and
suspension. In the event of run out, the
wheels should be balanced again. When a
new wheel is fitted, it should be balanced
again.
Running gear settings : an incorrectly posi-
tioned running gear increases the wear of
tyres and affects your safety while driving. If tyres wear too quickly, have the wheel align-
ment chec

ked at a specialised workshop. WARNING
If you notice unusual vibration or the car pulls
to one s ide whi

le driving, this may indicate
that one of the tyres is damaged.
● Reduce speed immediately and stop, while
obser
ving the highway code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or
wheels. Reque
st qualified assistance immedi-
ately.
● If there is no visible exterior damage, drive
slowly
and carefully to the nearest special-
ised workshop and have the vehicle checked. Tyre monitor system* 
