Opening and closing
Note
● Never l e
ave any valuable items in the vehi-
cle unattended. Even a locked vehicle is not a
safe.
● If the diode on the driver door sill lights up
for about 30 sec
onds when the vehicle is
locked, the central locking system or anti-
theft alarm* is not working properly. You
should have the fault repaired at a SEAT Offi-
cial Service or specialised workshop.
● The vehicle interior monitoring of the anti-
theft a
larm* system will only function as in-
tended if the windows and the sunroof* are
closed. Car key

Operation
The vehicle keys or new spare keys can be
o bt
ained fr
om a SEAT Official Service, a spe-
cialised workshop or an approved key service
qualified to create this kind of key.
New keys or spare keys must be synchron-
ised before use ››› page 123. CAUTION
All of the vehicle keys contain electronic com-
ponents. Pr ot

ect them from damage, impacts
and humidity. Note
● Only u

se the key button when you require
the corresponding function. Pushing the but-
ton unnecessarily could accidentally unlock
the vehicle or trigger the alarm. It is also pos-
sible even when you are outside the radius of
action.
● Key operation can be greatly influenced by
overl
apping radio signals close to the vehicle
working in the same range of frequencies, for
example, radio transmitters or mobile tele-
phones.
● Obstacles between the remote control and
the vehic
le, bad weather conditions and dis-
charged batteries can considerably reduce
the range of the remote control.
● If the buttons of the vehicle key are press-
ed ›››

Viewing Climatronic information
On the screen of Climatronic control unit and
on the screen of the factory-fitted Easy Con-
nect system, the theoretical values of the
temperature zones are shown.
The unit of temperature measurement can be
changed in the Easy Connect system.
Dust and pollen filter
The dust and pollen filter with its activated
charcoal cartridge serves as a barrier against
impurities in the air taken into the vehicle in-
terior.
The dust and pollen filter must be changed
regularly so that air conditioner performance
is not adversely affected.
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-
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
outside.
● The maximum 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

e 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 hi
ll/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 position S, D or R for an au-
tomatic gearbox.
This system is also active when reversing up-
hill. WARNING
● If y

ou do not start the vehicle immediately
after taking your foot off the brake pedal, the
vehicle may start to roll back under certain
conditions. Depress the brake pedal or use
the hand brake immediately.
● If the engine stalls, depress the brake ped-
al or u
se the hand brake immediately.
● When following a line of traffic uphill, if you
want t
o prevent the vehicle from rolling back
accidentally when starting off, hold the brake
pedal down for a few seconds before starting
off. Note

Safety

Driving
the Start-Stop system it is worth switching off
the en gine, f
or e
xample, at level crossings
and at traffic lights that remain red for long
periods of time. When an engine has reached
operating temperature, and depending on
the cylinder capacity, keeping it switched off
for a minimum of about 5 seconds already
saves more than the amount of fuel necessa-
ry for restarting.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high dur-
ing this initial warm-up phase. It is therefore
best to drive off immediately after starting
the engine. Avoid running the engine at high
speed.
Regular maintenance
Regular servicing helps in saving fuel even
before the engine is started. A well-serviced
engine gives you the benefit of improved fuel
efficiency as well as maximum reliability and
an enhanced resale value. A badly serviced
engine can consume up to 10% more fuel
than necessary.
Avoid short journeys
The engine and catalytic converter need to
reach their optimal operating temperature in
order to minimise fuel consumption and
emissions. A cold engine consumes a disproportionate
amount of
fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will re-
turn to a normal level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures ››› page 272 to save fuel. If
the pressure is below half bar, fuel consump-
tion may increase by 5%. Due to the greater
rolling resistance, under-inflation also increa-
ses tyre wear and impairs handling.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
Avoid carrying unnecessary loads
Given that every kilo of extra weight will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported.
Since the luggage rack increases the aerody-
namic drag of the vehicle, you should remove
it when not needed. At speeds of 100-120
km/h (62-75 mph), this will save 12% of fuel.
Save electrical energy
The engine drives the alternator, thereby gen-
erating electricity. This implies that any in-
crease in power consumption also increases
fuel consumption! For this reason, switch off any unneeded electrical devices. Devices that
use a lot of
electricity includes the blower at
a high setting, the rear window heating or
the seat heating*.

can occur in the exhaust purification system
(catalytic converter or diesel particulate fil-
ter), do not park the vehicle where the ex-
haust can come into contact with flammable
materials under the car (e.g. on grass or at
the forest edge). Fire hazard!
● Do not apply wax underneath the vehicle
