starting the engine. WARNING
Improper use of the socket or electrical devi-
ces could lead to a fire and cause serious in-
juries.
● Never leave children unsupervised in the
vehicle. The socket and equipment connected
to it can be used when the ignition is switch-
ed on.
● Should a connected electrical device over-
heat, switch it off and unplug it immediately. CAUTION
● Always follow the operating instructions for
the appliances to be connected!
● Never exceed the maximum power rating as
this could damage the vehicle's general elec-
trical system.
● 12 volt power socket:
– Only use accessories with approved elec-
tromagnetic compatibility according to
current regulations.
– Never power the socket. CAUTION
● To avoid damage to the vehicle's electrical
system, never connect equipment that gener-
ates electrical current, such as solar panels
or battery chargers, to the 12 Volt power sockets in order to charge the vehicle's bat-
tery.
● Only use accessories with approved elec-
tromagnetic compatibility according to cur-
rent regulations.
● To avoid damage due to voltage variations,
switch off all devices connected to the 12 V
socket before switching the ignition on or off
and before starting the engine.
● Never connect an appliance to the 12 Volt
power socket that consumes more than the
power indicated in watts. Exceeding the max-
imum power absorption could damage the ve-
hicle's electrical system. For the sake of the environment
Do not leave the engine running when the ve-
hicle is at a standstill. Note
● Using devices with the engine stopped and
the ignition switched on will drain the bat-
tery.
● Unshielded equipment can cause interfer-
ence on the radio equipment and the vehi-
cle's electrical system.
● If electrical equipment is used near an aer-
ial, you may observe interference in the re-
ception of AM stations. Loading luggage compartment
Introduction Always transport heavy loads in the luggage
compartment and place the seat backs in a
vertical position. Never overload the vehicle.
Both the carrying capacity as well as the dis-
tribution of the load in the vehicle have ef-
fects on the driving behaviour and braking
ability
››› .
WARNING
When the vehicle is not in use or being
watched, always lock the doors and the rear
lid to reduce the risk of serious injury or
death.
● Do not leave children unwatched, especial-
ly when the boot is open. Children could
climb into the luggage compartment, close
the rear lid from inside and be unable to es-
cape themselves. This could lead to serious
injury or death.
● Never allow children to play in or around
the vehicle.
● Never transport people in the luggage com-
partment. WARNING
Unsecured or incorrectly secured objects can
cause serious injury in case of a sudden ma-
noeuvring or breaking or in case of an acci-
dent. This is especially true when objects are » 73Technical specifications

Air conditioning
Heating, ventilation and air
conditioning system Introduction Dust and pollen filter
The dust and pollen filter with its activated
charcoal cartridge serves as a barrier against
impurities in the interior ambient air.
For the air conditioner to work with maximum
efficiency, the dust and pollen filter must be
replaced at the intervals specified in the
Maintenance Programme.
If the filter loses efficiency prematurely due
to use in areas with very high levels of air
pollution, the filter must be changed more
frequently than stated in the Service Sched-
ule.
WARNING
Reduced visibility through the windows in-
creases the risk of serious accidents. ●
Ensure that all windows are free of ice and
snow and that they are not fogged up pre-
venting a clear view of everything outside.
● The maximum heat output required to de-
frost 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
system, ventilation, air conditioner and the
heated rear window to maintain good visibili-
ty.
● 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 required. WARNING
Stuffy or used air will increase fatigue and re-
duce driver concentration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air recirculation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● Switch the air conditioner off if you think it
may be broken. This will avoid additional
damage. Have the air conditioner checked by
a specialised workshop.
● Repairs to the air conditioner require spe-
cialist knowledge and special tools. SEAT rec-
ommends taking your car in for technical
service. Note
● When the cooling system is turned off, air
coming from the outside will not be dried. To
avoid fogging up the windows, SEAT recom-
mends leaving the cooler (compressor) on. To
do this, press the A/C button. The button
lamp should light up.
● The maximum heat output required to de-
frost windows as quickly as possible is only
available when the engine has reached its
normal running temperature.
● Keep the air intake slots in front of the
windscreen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over. 80

instructions
Temperature
The desired temperature for the interior can-
not be lower than that of the exterior air tem- perature, as the heating and fresh air system
cannot cool or dehumidify the air.
Setting for conditions of optimal visibility
● Set the fan ››› Fig. 76 2 to setting 1 or 2.
● Turn the temperature control ››› Fig. 76 1 to the centre position.

User instructions for the air
conditioner* The interior cooling system only works when
the engine is running and the fan is switched
on.
The air conditioning operates most effective-
ly with the windows closed. However, if the
vehicle has heated up after standing in thesun for some time, the air inside can be
cooled more quickly by opening the windows
briefly.
Setting for conditions of optimal visibility
When the air conditioning is switched on, the
temperature and the air humidity in the vehi-
cle interior drop. In this way, when the out-
side air humidity is high, the windows do not
mist over and comfort for the vehicle occu-
pants is improved.
● Disable air recirculation mode
››› page 84.
● Set the f

an to the required setting.
● Turn the temperature control to the centre
position.
● Open and direct the air outlets in the dash
panel ››› page 83.
● Turn the air di

stribution control to the de-
frost position.

Air conditioning
● Press the A/C button to switch it on. The in-
dicator on the button will light up.
The cooling system does not switch on
If the air conditioning system cannot be
switched on, this may be caused by the fol-
lowing:
● The engine is not running.
● The fan is switched off.
● The air conditioner fuse has blown. ●
The outside temperature is lower than ap-
proximately +2 °C (+36 °F).
● The air conditioner compressor has been
temporarily switched off because the engine
coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner checked by a specialised work-
shop.
Things to note
If the humidity and temperature outside the
vehicle are high, condensation
can drip off the ev aporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak! Note
After starting it, any residual humidity in the
air conditioner could mist over the wind-
screen. Switch on the defrost function as
soon as possible to clear the windscreen of
condensation. Air vents

Important
Air recirculation mode prevents the ambient
air from entering the interior.
When the outside temperature is very high or
very low, selecting manual air recirculation
mode for a short period refreshes or heats
the interior more quickly.

Stuffy or used air will increase fatigue and re-
duce driver concentration possibly resulting
in a serious accident.
● Never use recirculation mode for long peri-
ods as it does not refresh the air inside the
vehicle.
● If the cooling system is switched off and air
recirculation mode switched on, the windows
can mist over very quickly, considerably limit-
ing visibility.
● Switch air recirculation mode off when it is
not required. CAUTION
Do not smoke when the air recirculation is ac-
tivated. The smoke taken in could lie on the
cooling system vaporiser and on the dust and
pollen filter, leading to a permanently un-
pleasant smell. Driving
Steering Introduction The power steering* is not hydraulic but elec-
tromechanical. The advantage of this steer-
ing system is that it disposes of hydraulic
tubes, hydraulic oil, the pump, filter and oth-
er components. The electromechanical sys-
tem saves fuel. While a hydraulic system re-
quires oil pressure to be maintained, electro-
mechanical steering only requires energy
when the steering wheel is turned.
With the power steering system, the assisted
steering function automatically adjusts ac-
cording to the vehicle speed, the steering tor-
que and the wheel turning angle. The power
steering only works when the engine is run-
ning.
WARNING
If the power steering is not working then the
steering wheel is much more difficult to turn
and the vehicle more difficult to control.
● 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 if
the vehicle is in motion. The steering may 84

Stopping and starting the
engine
Introduction Immobiliser display
When an invalid key is used or in the event of
a system fault,  is displayed on the instru-
ment panel. The engine cannot be started.
Pushing or towing
For technical reasons, the vehicle must
not
be push- or tow-started. Jump starting is pref-
erable. WARNING
Switching off the engine while driving makes
stopping the vehicle difficult. As a conse-
quence you may lose control of the vehicle
and there is a risk of serious accident.
● The assisted braking and steering systems,
the airbag system, seat belts and certain safety equipment are only active while the
engine is running.
●
The engine should only be switched off
when the vehicle is at a standstill. WARNING
While the engine is running or starting it
could help reduce the risk of serious injury.
● Never start or leave the engine running in
poorly ventilated or closed spaces. Exhaust
gas contains carbon monoxide, a toxic, col-
ourless and odourless gas. Carbon monoxide
can cause people to lose consciousness. It
can also cause death.
● Never leave the vehicle unattended if the
engine is running. The vehicle could move off
suddenly or something unexpected could
happen resulting in damage and serious in-
jury.
● Never use start boosters. Cold start sprays
could explode or increase the engine speed
unexpectedly. WARNING
The components of the exhaust system reach
very high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhaust system can come in contact with
flammable materials (such as wood, leaves,
spilled fuel, dried grass, etc). ●
Never apply additional underseal or anti-
corrosion coatings to the exhaust pipes, cata-
lytic converter or the heat shields on the ex-
haust system. Ignition lock

Key not authorised for the vehicle
If a key which is not authorised for this vehi-
cle is inserted in the ignition lock, it can be
removed as follows:
● Automatic gearbox : the key cannot be re-
moved from the ignition lock. Press and re-
lease the selector lever locking button. Key
can be removed from the vehicle.
● Manual gearbox : Remove the key from the
ignition. WARNING
Unsuitable or careless use of the vehicle key
could result in serious injury.
● Always take all the keys with you whenever
you leave the vehicle. If not, the engine could
accidentally be started and electrical equip-
ment such as the windows could accidentally
be operated resulting in serious injury.
● Never leave children or disabled people
alone in the car. Passengers could be trapped
in the car in an emergency and not be able to
get themselves 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 vehicle is in motion. The steering may
lock and it will not be possible to turn the
steering wheel. Note
● If the key 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 removed from the ignition lock if the
gear selector lever is in position P. In this
case, press and release the selector lever
locking button. Starting the engineComplete operations only in the sequence giv-
en.
1.Press the brake pedal and keep pressed until
step 5 has been completed.

4.When the engine has started, release the key
in the ignition lock.
5.If the engine does not start, stop the processand try again after one minute.
6.Release the handbrake when you want to be- gin driving ››› page 89. WARNING
Never leave the vehicle unattended if the en-
gine is running. The vehicle could move off
suddenly, especially if it is in gear, resulting
in an accident and serious injury. WARNING
Cold start sprays could explode or cause a
sudden increase in the engine speed.
● Never use start boosters. CAUTION
● An attempt to 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 acceleration and do not make the
engine work hard.
● Do not push or tow start the engine. Un-
burnt fuel could damage the catalytic con-
verter. For the sake of the environment
Do not warm the engine at idle speed; start
driving immediately if the visibility is OK.
This helps the engine reach operating tem-
perature faster and reduces emissions. » 87

the engine starts.
● When the engine is started cold, there may
be strong 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, as 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 engineComplete operations only in the sequence giv-

6.With a manual gearbox, put the vehicle in first
or reverse gear. WARNING
Never switch off the engine while the vehicle
is moving. 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 is switched off.
● The brake servo does not work with the en-
gine off. To 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
steering may lock and it will not be possible
to steer the vehicle. CAUTION
If the engine has been driven at high speed
for a prolonged period of time, it may over-
heat when turned off. To avoid engine dam-
age, allow the engine to run for approximate-
ly 2 minutes in neutral before switching it off. Note
After stopping the engine, the engine com-
partment fan may continue running for a few
minutes, even when the ignition has been
switched off or the key removed. The radiator
fan is automatically switched off. Electronic immobiliser
The gear lock prevents the engine from being
started with an unauthorised key and the ve-
hicle being moved.
The vehicle key has a built-in chip. It auto-
matically deactivates the electronic immobil-
iser when the key is inserted into the ignition
lock.
The electronic immobilizer will be activated
again automatically as soon as you remove
the key from the ignition lock.
For this reason, the vehicle can only be used
with a genuine SEAT key with the correct
code. Coded keys can be obtained from SEAT
dealerships

Braking and parking Introduction The assisted braking systems
are the elec-
tr
onic distribution of the brake force (EBV),
the anti-lock brake system (ABS), the brake
assist system (BAS), the electronic differen-
tial lock (EDL), the traction control (TC), the
traction control system (ASR) and the elec-
tronic stability control (ESC*). WARNING
Driving with worn brake pads or a faulty
brake system may lead to serious accident.
● If you believe the brake pads to be worn or
the brake system to be faulty, immediately
refer to a specialised workshop to check the
brake pads and replace the worn ones. WARNING
Careless parking can cause serious injury.
● Never remove the key from the ignition if
the vehicle is in motion. The steering lock
may engage and lock the steering wheel mak-
ing the vehicle impossible to control.
● Always park your vehicle so that no part of
the exhaust system can come in contact with
flammable materials (such as wood, leaves,
dried grass, spilled fuel, etc.).
● Always apply the handbrake when you
leave your vehicle and when you park. ●
Never leave children or disabled people
alone in the vehicle. They could release the
electronic parking brake, activate the selec-
tor lever or gear stick and start the vehicle
moving. This could result in a serious acci-
dent.
● Always take all the keys with you whenever
you leave the vehicle. The engine could acci-
dentally be started and electrical equipment
such as the windows could accidentally be
operated resulting in serious injury.
● Never leave children or disabled people
alone in the car. They could be trapped in the
car in an emergency and will not be able to
get themselves 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. CAUTION
● Special 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 entrances, 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. Warning and control lamps
