and in a safe pl
ace. Note
Failure to heed the control lamps and corre-
sponding t e

xt messages when they light up
may result in damage to the vehicle. Information relating to different vehi-
cle pr
oc

esses. In order to make the vehicle more difficult to
ste
al,

you should always lock the steering be-
fore leaving the vehicle.
Mechanical steering lock
The steering column is locked when the key
is removed from the ignition lock and the ve-
hicle is stationary.
Activating the steering lock
● Park the vehicle ›››

p
age 152.
● Remove the ignition key.
● Turn the steering wheel slightly until the
steering loc
k has engaged.
Deactivating the steering lock
● Turn the steering wheel slightly to release
the lock.
● Insert

the key in the ignition lock.
● Hold the steering wheel in this position
and switch on the ignition. El

ectromechanical steering
In vehicl
es with electromechanical steering,
the assisted steering function automatically
adjusts according to vehicle speed, steering
wheel torque and wheel orientation. The
power steering only works when the engine
is running.
You should take into account that you will
need considerably more power than normal
to steer the vehicle if the power steering is
not working correctly or at all.
Power-assisted steering
Power-assisted steering helps the driver in
critical situations. In counter-steering, it as-
sists by applying additional torque ››› .
WARNING
Power-assisted steering, together with the
ESC, helps the driv

er to control vehicle steer-
ing in critical situations. However, the driver
is ultimately responsible for steering the ve-
hicle at all times. Power-assisted steering
does not remove this responsibility. 149

diately blocked- Risk of accident!
● Always remove the key from the ignition
when leavin
g the vehicle, even if only for a
short period. This is especially important if
children or disabled people are left alone in
the vehicle. They could accidentally start the
engine or work electrical equipment such as
the electric windows, resulting in an acci-
dent. ●
Unsuper v

ised use of the key could start the
engine or any electrical system, such as the
electric windows. This could result in serious
injury. CAUTION
The starter motor will only work when the en-
gine i s st

opped (ignition key position 3 ).
Electronic immobiliser “SAFE”
The electronic immobiliser prevents unau-

Inside the key there is a chip that deactivates
the electronic immobiliser automatically
when the key is inserted into the ignition.
The electronic immobiliser will be activated
again automatically as soon as you pull the
key out of the ignition lock.
The engine can only be started using a genu-
ine SEAT key with its correct code.
If the following message* is shown on the in-
strument panel display: SAFE, the vehicle
cannot be started.
The engine can, however, be started if the
appropriate coded SEAT genuine key is used.

After starting a very hot engine, you may
need to slightly press down the accelerator.
When starting a cold engine, it may be a little
noisy for the first few seconds until oil pres-
sure has built up in the hydraulic valve com-
pensators. This is quite normal, and no cause
for concern.
If the engine does not start immediately,
switch the starter off after 10 seconds and try
again after half a minute. If the engine still
does not start, the fuel pump fuse should be
checked ›››
page 81, Fuses. WARNING
● Never st ar

t or run the engine in unventila-
ted or closed rooms. The exhaust gases con-
tain carbon monoxide, an odourless and col-
ourless poisonous gas. Risk of fatal acci-
dents. Carbon monoxide can cause loss of
consciousness and result in death.
● Never leave the vehicle unattended if the
engine is ru
nning.
● Never use “cold start sprays”, they could
explode or cau
se the engine to run at high
revs. Risk of injury. CAUTION
● When the engine is c

old, you should avoid
high engine speeds, driving at full throttle
and over-loading the engine. Risk of engine
damage.
● The vehicle should not be pushed or towed
more than 50 metre
s to start the engine. Un-
burnt fuel could enter the catalytic converter
and damage it.
● Before attempting to push-start or tow a ve-
hicle in order t

ching the engine off, the radiator
fan may run on for up to 10 minutes. It is also
possible that the fan turns itself on once
more if the coolant temperature increases
due to the heat accumulated in the engine
compartment or due to its prolonged expo-
sure to solar radiation. WARNING
● Never swit c

h the engine off until the vehi-
cle is completely stationary.
● The brake servo works only when the en-
gine is runnin
g. With the engine switched off,
more strength is needed to brake. As normal brake operation cannot be performed, risk of
accident
s

and serious injury may exist.
● The steering lock can be immediately

apacity and braking distance The efficiency of the brakes depends directly
on the br
ak
e p a

d wear. This wear depends to
a great extent on the conditions under which
the vehicle is operated and the way the vehi-
cle is driven. If you often drive in town, drive
short distances or have a sporty driving style,
we recommend that you have the thickness
152

Driving
of your brake pads checked by technical serv-
ic e
s mor
e frequently than recommended in
the Maintenance Programme.
If you drive with wet brakes, for example, af-
ter crossing areas of water, on days of heavy
rainfall or even after washing the car, the ef-
fect of the brakes is reduced as the brake
discs are wet or even frozen (in winter): in
this case, the brakes should be “dried” by
pressing the brake pedal several times. WARNING
Longer braking distances and faults in the
brake sy s

tem increase the risk of accidents.
● New brake pads must be run in and do not
have the corr
ect friction during the first
200 km. This reduced braking capacity may
be compensated for by pressing on the brake
pedal a little harder, which also applies when
the brake pads have to be changed further
on.
● If brakes are wet or frozen, or if you are
driving on ro
ads which have been salted,
braking power may be lower than normal.
● On steep slopes, if brakes are excessively
used, they wi
ll overheat. Before driving down
a long steep slope, it is advisable to reduce
speed and change down into a lower gear or
range (depending on the type of transmis-
sion). Thus, make use of engine braking and
relieve the brakes.
● Never let the brakes “drag” by applying
light pres
sure. Continuous braking will cause the brakes to overheat and the braking dis-
tance w
i

ll increase. Apply and then release
the brakes alternately.
● Never let the vehicle run with the engine
switched off
. The braking distance is in-
creased considerably when the brake servo is
not active.
● If the brake fluid loses its viscosity and is
subject
ed to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes.
● Non-standard or damaged front spoilers
could r
estrict the airflow to the brakes and
cause them to overheat. Before purchasing
accessories please observe the relevant in-
structions ››› page 190, Modifications.
● If a brake system circuit fails, the braking
distanc
e will be increased considerably. Con-
tact a specialised workshop immediately and
avoid unnecessary journeys. Control lamp

level in the reservoir is too low so there is a
risk of an accident ››› page 209, Brake fluid.
Stop the vehicle and do not drive on. Obtain
technical assistance.
● If the brake warning lamp lights up  to-
gether with the ABS

due to an ABS fault. This could cause the rear
wheels to lock quickly when you brake. This
could cause the rear to break away. Risk of

● Never use the h andbr

ake to stop the vehi-
cle when it is in motion. The braking distance
is considerably longer, because braking is
only applied to the rear wheels. Risk of acci-
dent!
● If the handbrake is only partially released,
this wi
ll cause the rear brakes to overheat,
which can impair the function of the brake
system and could lead to an accident. This al-
so causes premature wear on the rear brake
pads. CAUTION
Always apply the handbrake before you leave

cles with an automatic gearbox, place the
gear lever in position P. Parking
The handbrake should always be firmly ap-
plied when the v
ehic

le is parked.
Always note the following points when park-
ing the vehicle: – Use the brake pedal to stop the vehicle.
– Apply the handbrake.
– Put it in 1st gear.
– Switch the engine off and remove the key
from the ignition. T urn the s

teering wheel
slightly to engage the steering lock.
– Always take you keys with you when you
leave the

vehicle ››› .
Ad dition
al
notes on parking the vehicle on
gradients:
Turn the steering wheel so that the vehicle
rolls against the kerb if it started to roll.
● If the vehicle is parked facing downhill
,
turn the front wheels so that they point to-
wards the kerb . ●
If the vehic
le is parked facing uphill, turn
the front wheels so that they point away from
the kerb.
● Secure the vehicle as usual by applying the
handbrake firm
ly and putting it in 1st gear. WARNING
● Take me a

sures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
could ignit
e inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehicl
e when it is locked. They would be
unable to open the vehicle from the inside,
and could become trapped in the vehicle in
an emergency. In the event of an emergency,
locked doors will delay assistance to vehicle
occupants.
● Never leave children alone in the vehicle.
They coul
d set the vehicle in motion, for ex-
ample, by releasing the handbrake or the
gearbox lever.
● Depending on weather conditions, it may
become extremely
hot or cold inside the vehi-
cle. This can be fatal. 154

Driving
Braking and stability systems El ectr
onic
Stability Control (ESC)*This Electronic Stability System reduces the
risk of
sk

idding and improves the vehicle's
stability and ability to hold the road.
The Electronic Stability Control (ESC) contains
the electronic differential lock (EDL) and the
traction control system (ASR). The ESC works
together with the ABS. Both control lamps
will light up if the ESC or ABS systems are
faulty.
The ESC system is started automatically
when the engine is started.
The ESC system is always active and cannot
be switched off. With the Easy Connect sys-
tem it is only possible to deactivate the ASR
or else select Sport mode.
The ASR can be deactivated when wheel spin
is desirable ›››
page 156.
For example:
● When driving with snow chains.
● When driving in deep snow or on loose sur-
face s.
● When the

vehicle is stuck, to rock it back-
wards
and forwards.
Press the button to switch the ASR back on
when you no longer need wheel spin. Electronic Stability Control (ESC)*
The ESC reduc

es the risk of skidding by brak-
ing the wheels individually.
The system uses the steering wheel angle
and road speed to calculate the changes of
direction desired by the driver, and constant-
ly compares them with the actual behaviour
of the vehicle. When irregularities occur, for
example, if the vehicle begins to skid, the
ESC brakes the appropriate wheel automati-
cally.
The forces acting on the braked wheel bring
the vehicle back to a stable condition. If the
vehicle tends to oversteer (the rear end
slides out), the system will act on the front
wheel on the outside of the turn.
Control lamp
There are two control lamps for the electronic
stability control. The lamp  provides infor-
mation concerning function and  disconnec-
tion status.
Both control lamps light up together when
the ignition is switched on and should turn
off after approximately 2 seconds. This is the
time taken for the function check.
This programme includes the ABS, EDL and
ASR. It also includes emergency braking as-
sistance (BAS). The control lamp
 has the f ollowing func-
tions:
● It flashes whilst driving when the ASR/ESC
is activat
ed.
● It will light up if there is a fault in the ESC.
● As the ESC operates in conjunction with the
ABS, the ESC light w
ill also come on if a fault
should occur in the ABS.
If the ESC control lamp  lights up and stays
on after the engine is started, this may mean
that the control system has temporarily
switched off the ESC. In this case the ESC can
be reactivated by switching the ignition off
and then on again. If the control lamp goes
out, this means the system is fully functional.
The  lamp provides information about the
disconnection status of the system:
● It stays lit when the ASR is disconnected on
press
ing the switch  or if we select ESC
Sport mode, only by means of Easy Connect. WARNING
● Do not for g

et that the electronic stability
control ESC cannot defy the laws of physics.
This should be kept in mind, particularly on
slippery and wet roads and when towing a
trailer.
● Always adapt your driving style to suit the
condition of the ro
ads and the traffic situa-
tion. The greater safety provided by the ESC
should not encourage you to run any risks. » 155

Operation
CAUTION
● To ens ur
e that the ESC works correctly, all
four wheels must be fitted with the same
tyres. Any differences in the rolling radius of
the tyres can cause the system to reduce en-
gine power when this is not desired.
● Any modifications made to the vehicle (for
exampl
e, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS, EDL, ESC and ASR. Traction control system (ASR)*
The traction control system prevents the driv-
en wheel
s
fr om s

pinning when the vehicle is
accelerating. This system always includes
ABS.
Description and operation of the traction
control system during acceleration (ASR)
On front-wheel drive vehicles, the ASR sys-
tem intervenes, reducing engine power and
preventing the driven wheels from slipping
during acceleration. The system works in the
entire speed range in conjunction with ABS.
If a failure occurs in the ABS, the ASR will al-
so stop working.
TCS helps the car to start moving, accelerate
and climb a gradient in slippery conditions
where this may otherwise be difficult or even
impossible. The ASR automatically switches on when the
engine is s

tarted. If necessary, it could be
connected or disconnected by means of the
Easy Connect system.
When the ASR is off, the warning lamp lights
up . The ASR should normally be left on.
Only in exceptional circumstances, when
wheel spin is required, can they be turned off
using the ESC button, for example:
● With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on soft ter-
rain.
● When the vehic

le is bogged-down, to free it
“by roc
king it.”
The ASR should be switched on again as
soon as possible.
Control lamp
There are two control lamps for the traction
control system:  and . Both control lamps
light up together when the ignition is switch-
ed on and should turn off after approximately
2 seconds. This is the time taken for the func-
tion check.
The  lamp has the following function:
● It flashes when the ASR is working if the ve-
hicle is
moving. If the system is deactivated or if it has any
fault, the warnin

g lamp will remain lit. The
warning lamp will also light up if a fault
should occur in the ABS because the ASR op-
erates in conjunction with the ABS. For fur-
ther information, see ››› page 156.
The  lamp provides information about the
disconnection status of the system:
● It stays lit when the ASR is disconnected
via Ea
sy Connect.
By means of Easy Connect, the ASR function
is reactivated and the warning lamp switched
off. WARNING
● Remember that not

even the ASR can defy
the laws of physics. This should be kept in
mind, particularly on slippery and wet roads
and when towing a trailer.
● Always adapt your driving style to suit the
condition of the ro
ads and the traffic situa-
tion. The greater safety provided by the ASR
should not encourage you to run any risks. CAUTION
● To ens ur

e that the ASR works correctly,
identical tyres should be fitted on all four
wheels. Any differences in the rolling radius
of the tyres can cause the system to reduce
engine power when this is not desired. 156

Driving
●
Any modific ation
s made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS and ASR. Connecting/disconnecting ESC and
ASR
The ESC is switched on automatically when
the engine is
s

tarted, and only works when
the engine is running and includes the ABS,
EDS and ASR systems.
The ASR and ESC function should only be
switched off in situations in which traction is
insufficient, among others:
● When driving in deep snow or on surfaces
that ar e not

very firm.
● To “free” the vehicle if it gets stuck.
Then switch the ASR and E
SC function back
on.
Depending on finishes and versions, it is
possible either to disconnect only the ASR or
else activate ESC Sport mode.

tions where this may otherwise be difficult or
even impossible.
It uses the ABS sensors to monitor the speed
of the driven wheels. »

Safety

Operation
At speeds of up to approximately 80 km/h
(50 mph), it i
s ab
le to balance out differences
in the speed of the driven wheels of approxi-
mately 100 rpm/min caused by a partially
slippery road surface. It does this by braking
the wheel which has lost traction and distrib-
uting more driving force to the other driven
wheel via the differential.
To prevent the disc brake of the braking
wheel from overheating, the EDL cuts out au-
tomatically if subjected to excessive loads.
The vehicle will continue to function normally
without EDL. For this reason, the driver is not
informed that the EDL has been switched off.
The EDL will switch on again automatically
when the brake has cooled down.
Control lamp
A malfunction in the EDL is indicated by the
ABS control lamp  ››› page 158. Take the
vehicle to a specialised workshop as soon as
possible. WARNING
● When accel er

ating on a slippery surface,
for example on ice and snow, press the accel-
erator carefully. Despite EDL, the driven
wheels may start to spin. This could impair
the vehicle's stability.
● Always adapt your driving style to suit road
conditions and the tr
affic situation. Do not let
the extra safety afforded by EDL tempt you in- to taking any risks when driving, this can
cause ac
c

idents. CAUTION
Modifications to the vehicle (e.g. to the en-
gine, the br ake sys

but not with maximum force. This results in
unnecessarily long braking distances.
This is when the brake assist system comes
into action. When pressing the brake pedal
rapidly, the assistant interprets it as an emer-
gency. It very quickly builds up the full brake
pressure so that the ABS can be activated
more quickly and efficiently, thus reducing
braking distance.
Do not reduce the pressure on the brake ped-
al, since the brake assist system switches off
automatically as soon as you release the
brake. Automatic hazard warning lights activation
The brake lights fl

ash automatically to indi-
cate that the vehicle is braking suddenly or in
an emergency situation. If the emergency
braking continues until the vehicle comes to
a standstill, the hazard warning lights will
then come on and the brake lights will re-
main on permanently from that moment. The
warning lights will automatically switch off
when the vehicle begins to move again or
when the "warning" light button is pressed. WARNING
● The risk of ac

cident is higher if you drive
too fast, if you do not keep your distance from
the vehicle in front, and when the road sur-
face is slippery or wet. The increased acci-
dent risk cannot be reduced by the brake as-
sist system.
● The brake assist system cannot defy the
laws
of physics. Slippery and wet roads are
dangerous even with the brake assist system!
Therefore, it is essential that you adjust your
speed to suit the road and traffic conditions.
Do not let the extra safety features tempt you
into taking any risks when driving. Anti-lock brake system (ABS)
