Pollution filter
The pollution filter (a combined particulate
filter and active carbon filter) serves as a bar-
rier against impurities in the outside air, in-
cluding dust and pollen.
For the climate control system to work with
maximum efficiency, the pollution filter must
be replaced at the specified intervals in the
Maintenance Programme.
If the filter loses efficiency prematurely due
to use in areas reaching very high pollution
levels, the pollen filter must be changed
more frequently than stated in the Service
Schedule. WARNING
Reduced visibility through the windows in-
cr e

ases the risk of serious accidents.
● Always ensure that all windows are free of
ice and sno
w, and that they are not fogged, so as to maintain good visibility of everything
outs
ide.
● The m

aximum heat output required to de-
fros
t windows as quickly as possible is only
available when the engine has reached its
normal running temperature. Only drive when
you have good visibility.
● Always ensure that you use the heating
syst
em, fresh air system, air conditioner and
the heated rear window to maintain good visi-
bility to the outside.
● Never leave the air recirculation on for a
long period of time. If
the cooling system is
switched off and air recirculation mode
switched on, the windows can mist over very
quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is
not requir
ed. WARNING
Stuffy or used air will increase fatigue and re-
duce driv er c

oncentration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air rec
irculation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● If y

ou suspect that the air conditioner is
damaged, switch it off with the A/C button to prevent further damage and have it checked
by
a s

pecialised workshop.
● Repairs to the air conditioner require spe-
cia
list knowledge and special tools. There-
fore, we recommend you to take the vehicle
to a specialised workshop. Note
● If the humidity and t

emperature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak.
● Keep the air intake slots in front of the
winds
creen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over.
● The air from the vents flows through the ve-
hicle int
erior and is extracted by slots in the
luggage compartment designed for this pur-
pose. Therefore, you should avoid obstruct-
ing these slots with any kind of object.
● The air conditioner operates most effective-
ly with the w
indows closed. However, if the
temperature inside the vehicle is excessive
because of the sun, the air inside can be
cooled faster by opening the windows for a
short time.
● Do not smoke while air recirculation mode
is on, a
s smoke drawn into the air condition-
ing system leaves residue on the evaporator,
producing a permanent unpleasant odour. 158

Air conditioning
●
At lo w out
side temperatures, the compres-
sor switches off automatically and cannot be
switched on even with the AUTO button.
● It is advisable to turn on the air condition-
ing at l

east once a month, to lubricate the
system gaskets and prevent leaks. If a de-
crease in the cooling capacity is detected, a
Technical Service should be consulted to
check the system.
● To ensure correct operation, the grilles on
both sides
of the screen must not be obstruc-
ted. ●
When the engine i s

under extreme strain,
switch off the compressor for a moment. Economic use of the air conditioning
When the air conditioning is switched on, the
compr
e

ssor consumes engine power and has
influence on fuel consumption. Consider the
following points in order to have the system
operating in the minimum possible time. ●
If the v

ehicle interior has overheated due to
an excessive solar radiation, it is best to
open the windows or doors to allow the hot
air to escape.
● While in motion, the air conditioning
should not
be switched on if the windows are
open.
Air outlets Fig. 169
Air vents. To ensure proper heating, cooling and venti-
l
ation in the

Interior cooling
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.

Introduction The power steering is not hydraulic but elec-
tromec
h

anical. 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 mor e s

trength to turn the wheel.
This has a considerable effect on vehicle
safety.
● The power steering only works when the
engine is
running.
● Never allow the vehicle to move when the
engine is
switched off.
● Never remove the key from the ignition
while the
vehicle is moving. The steering lock could be engaged and vehicle steering would
not w
ork. Note
The ignition of the vehicle being towed must
be sw itc

hed on to prevent the steering wheel
from locking and also to allow the use of the
turn signals, horn, windscreen wipers and
washers. Control lamp
The control lamp should light up for a few
sec

Seek specialist assistance. WARNING
If the warning lamps and the corresponding
mes s

ages 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.

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 ››
›

page 174.
● Remove the ignition key.
● Turn the steering wheel slightly until the
steerin
g lock has engaged.
Deactivating the steering lock
● Turn the steering wheel slightly to release
the lock.
● Inser

t the key in the ignition lock.
● Hold the steering wheel in this position
and switc
h on the ignition. Electromechanical steering
In vehic

les 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, help s

the driver 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. Starting and stopping the en-

Driving
Switching the ignition or the glow plug sys-
t em on 2 Turn the ignition key to this position and re-
l
e
a
se it. If the key cannot be turned or it is
difficult to turn from position 1 to position
2 , move the steering wheel from one side to
the other; thi s
w

ill release it.
Starting 3The engine is started when the key is in this
po
s
ition. El

ectrical devices with high power
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
r epetitiv
e s

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

st 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 leav
ing 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. ●
Uns uper

vised 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 s

topped (ignition key position 3 ).
Electronic immobiliser “SAFE”
The electronic immobiliser prevents unau-
thori
sed per
son

s 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. Note
A perfect operation of the vehicle is ensured
if g enuine

SEAT keys are used. Starting petrol engines
The engine can only be started using a genu-
ine S
EA

T key with its correct code.
– Move the gearbox lever to the neutral posi-
tion and depres

s the clutch pedal thor-
oughly and hold it in this position for the
starter to turn the engine on.
– Turn the ignition key to the starting posi-
tion ››
›

page 168.
– Let go of the ignition key as soon as the en-
gine star

ts; the starter motor must not run
on with the engine.
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 ›››
