output, which is needed to
defrost the windows quickly, is only available
when the engine has reached its operating
temperature.
Coolant system
When the air conditioning is switched on, the
temperature and the air humidity go down.
This way, if the outside humidity is extreme,
the air conditioning prevents the misting of
the windows and therefore, comfort is im-
proved.
If the air conditioning does not work, this
may be due to the following reasons:
● The engine is stationary.
● The fan blower is switched off.
● The outside temperature is lower than ap-
proxim
ately +3 °C (+37 °F).
● The air conditioning system compressor
has been t
emporarily switched off because of
an increased engine coolant temperature.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air
conditioning chec
ked by a specialised work-
shop. Air recirculation
 Air recirculation prevents unpleasant smells,
e.g. when pa
s

sing through a tunnel or in
queuing traffic, from entering the interior.
If the rotary switch C

thaw position, the recirculation flap will al-
ways be open (button light off).
If the rotary switch C is switched from any
position t o the th

Disconnecting the recirculation
In any position of rotary switch C except
th a
w:
● Pr e

ss button D again and the button's
l amp w
il

l go off, indicating that air recircula-
tion from the outside has been activated. In the thaw position of rotary switch
C , the
entr y
of air int

o the vehicle interior is always
from the outside. WARNING
In air recirculation mode, no cold air from the
outside ent er

s the vehicle interior. If the air
conditioner is switched off, the windows can
quickly mist over. Therefore, never leave the
air recirculation mode switched on for a long
time (risk of accident). Note
● When engagin g r

everse gear, the air recir-
culation is connected automatically to pre-
vent the entrance of exhaust gases in the ve-
hicle on travelling backwards. The control
lamp on the button  does not light up.
● If the temperature control is turned to the
col de

st setting (blue point) and the A/C but-
ton is on, the
“Air recirculation” function is
automatically activated in order to cool the
vehicle faster using less energy, and its func-
tion control lamp will light up.
● If the function is not deactivated by press-

and the blower and air distribution levels.
The system also allows for the effect of sun-
light, so there is no need for manual adjust-
ment. It also has a humidity sensor that
helps to automatically demist the wind-

Introduction The power steering is not hydraulic but elec-
tromech
anic

al. The advantage of this steer-
ing is that it foes not need flexible hydraulic
pipes, hydraulic oil, pump, filter or other
parts. The electromechanical system saves
fuel. Whereas a hydraulic system needs con-
tinuous oil pressure, electromechanical
steering only needs power when it is used.
In vehicles 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. WARNING
If the power steering does not work, you will
need much more s tr

ength to turn the wheel.
This has a considerable effect on vehicle
safety.
● The power steering only works when the
engine is ru
nning.
● Never allow the vehicle to move when the
engine is sw
itched off.
● Never remove the key from the ignition
while the v
ehicle is moving. The steering lock could be engaged and vehicle steering would
not work.
Note
The ignition of the vehicle being towed must
be sw itched on t

o prevent the steering wheel
from locking and also to allow the use of the
turn signals, horn, windscreen wipers and
washers. Control lamp

panel display.
Do not drive on if
the steering
column remains locked after the
ignition has been switched on.
Seek specialist assistance. WARNING
If the warning lamps and the corresponding
mess ag

es are ignored when they light up, the
vehicle may stall in traffic and cause acci-
dents and severe injuries.
● Never ignore the warning lamps or messag-
es.
● Stop the v

ehicle at the next opportunity
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

consumption are switched off temporarily at
the same time.
Each time that the vehicle is restarted, the ig-
nition key must be turned to position 1 . The

art prevention lock of the igni-
tion prevents possible damage to the starter
motor if the engine is already running. WARNING
● The ignition key mu s

t NOT be removed from
the lock until the vehicle comes to a stand-
still. Otherwise, the steering could be imme-
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-
thori
sed per
sons

from driving the vehicle.
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
o start it, you should first try to
start it using the battery of another vehicle.

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
blocked onc

Br ak
ing c

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

or if it lights up when driving, the brake fluid
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
the vehic l

e. Put it in 1st gear as well. In vehi-
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

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
