Operation
Note
Always read the assembly instructions that
come with the crossbars and the roof carrier
system carefully and keep them in the vehi-
cle. Loading the roof carrier system
The load can only be secured if the crossbars
and the roof carrier system are properly in-
stalled
››› .
Maximum authorised roof load
The maximum permissible roof load is 75 kg.
This figure comes from the combined weight
of the roof carrier, the cross bars and the load
itself on the roof ››› .
Always check the weight of the roof carrier
system, the cross bars and the weight of the
load to be transported and weigh them if
necessary. Never exceed the maximum au-
thorised roof load.
If you are using cross bars and a roof carrier
with a lower weight rating, you will not be
able to carry the maximum authorised roof
load. In this case, do not exceed the maxi-
mum weight limit for the roof carrier which is
listed in the fitting instructions. Distributing a load
Distribute loads uniformly and secure them
correctly
››› .
Check attachments
Once the cross bars and roof carrier system
have been installed, check the bolted con-
nections and attachments after a short jour-
ney and subsequently with a certain frequen-
cy. WARNING
Exceeding the maximum authorised roof load
can result in accidents and considerable vehi-
cle damage.
● Never exceed the maximum authorised
load on the roof and on the axles or the vehi-
cle's maximum authorised weight.
● Never exceed the load capacity of the cross
bars and the roof carrier system, even if the
maximum authorised roof load has not been
reached.
● Secure heavy items as far forward as possi-
ble and distribute the vehicle load uniformly. WARNING
If the load is loose or not secured, it could fall
from the roof carrier system or cause acci-
dents and injuries.
● Always use belts or retaining straps that
are suitable and in a good condition.
● Secure the load properly. Air conditioning

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.

Air conditioning
WARNING
Reduced visibility through the windows in-
creases the risk of serious accidents.
● Always ensure that all windows are free of
ice and snow, and that they are not fogged,
so as to maintain good visibility 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, 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 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 visiting a SEAT Official Service. Note
● When the cooling system is turned off, air
coming from the outside will not be dried. To
prevent fogging of the windows, SEAT recom-
mends leaving the cooling system (compres-
sor) turned on. To do this, press the 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. Adjust using the Easy Connect
system*

The essentials

Operation
Economical and environmentally
friendly driving Fuel consumption, environmental pollution
and wear to the engine, brakes and tyres de-
pends largely on driving style. Fuel consump-
tion can be reduced by 10-15% with an eco-
nomical driving style and proper anticipation
of traffic conditions. The following section
gives you some tips on lessening the impact
on the environment and reducing your oper-
ating costs at the same time.
Active cylinder management (ACT
®
)*
Depending on vehicle equipment, the active
cylinder management (ACT ®
) may automati-
cally deactivate some of the engine cylinders
if the driving situation does not require too
much power. When it is switched off, no fuel
is injected into these cylinders, hence total
fuel consumption may be reduced. The num-
ber of active cylinders can be seen on the in-
strument panel display ›››
page 74.
Foresight when driving
Acceleration causes the vehicle to consume
more fuel. If you think ahead when driving,
you will need to brake less and thus acceler-
ate less. Wherever possible, let the car roll
slowly to a stop, with a gear engaged (for in-
stance when you can see that the next traffic
lights are red). This takes advantage of the
engine braking effect, reducing wear on the brakes and tyres. Emissions and fuel con-
sumption will drop to zero due to the overrun
fuel cut-off.
Changing gear to save energy
An effective way of saving is to change
in ad-
vance to a higher gear. Running the engine at
high rpm in the lo w
er gears uses an unneces-
sary amount of fuel.
Manual gearbox : shift up from first to second
gear as soon as possible. In any case, we rec-
ommend that you change to a higher gear
upon reaching 2,000 rpm. Choosing the right
gear enables fuel savings. Select the highest
possible gear appropriate for the driving sit-
uation (the engine should continue function-
ing with cyclical regularity).
Automatic gearbox : accelerate gradually and
without reaching the “kick-down” position.
Avoid driving at high speed
Avoid travelling at top speed, whenever pos-
sible. Fuel consumption, emission of harmful
gases and noise pollution multiply dispropor-
tionately as speed is increased. Driving at
moderate speeds will help to save fuel.
Reduce idling time
In vehicles with the Start-Stop system idling
is automatically reduced. In vehicles without
the Start-Stop system it is worth switching off
the engine, for example, 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 enhanc
ed 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

Operation
Note
The Official Service or a specialist workshop
can tell you if your vehicle is equipped with
this system. Start-Stop system*
Description and operation The Start-Stop system helps save fuel and re-
duce CO
2 emissions.
In Start-Stop mode, the engine will automati-
cally switch off when the vehicle stops, when
stopping at traffic lights for example. The ig-
nition remains switched on during the stop-
ping phase. The engine automatically
switches back on when required.
As soon as the ignition is switched on, the
Start-Stop function is automatically activa-
ted.
Basic requirements for the Start-Stop mode ● The driver door must be closed.
● The driver must have their seat belt fas-
tened.
● The bonnet must be closed.
● The vehicle must have travelled at more
than 4 km/h (2 mph) since the last stop.
● The vehicle cannot be towing a trailer. WARNING
● Never switch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake.
As you cannot steer and brake in the normal
manner, there is a greater risk of accidents
and serious injury.
● Never remove the key from the ignition if
the vehicle is in motion. Otherwise, the steer-
ing could lock making it impossible to steer
the vehicle.
● To avoid injury, make sure that the Start-
Stop system is switched off when working in
the engine compartment ››› page 149. CAUTION
The Start-Stop system must always be
switched off when driving through flooded
areas ››› page 149. Stop/Start the engine
Vehicles with a manual gearbox
– When the vehicle is stopped, put it into
neutral and release the clutch pedal. The
engine will switch off. The warning lamp 
will appear on the instrument panel dis-
play. –
When the clutch pedal is pressed the en-
gine will start up again. The warning lamp
will switch off.
Vehicles with an automatic gearbox
– Use the foot brake to bring the vehicle to a
stop and keep the brake pedal pressed
down with your foot. The engine will switch
off. The warning lamp  will appear in the
di s
play.
– When you take your foot off the brake pedal
the engine will start up again. The warning
lamp will switch off.
Additional information related to the
automatic gearbox
The engine stops when the selector lever is in
the positions P, D, N and S, in addition to
when in manual mode. With the selector lev-
er in position P, the engine will also remain
switched off when you take your foot off the
brake pedal. In order to start the engine up
again the accelerator must be pressed, or an-
other gear engaged or the brake released.
If the selector lever is placed in position R
during the stopping phase, the engine will
start up again.
Change from position D to P to prevent the
engine from accidentally starting when
changing and passing by position R.

● The dis

play on the Easy Connect screen
shows a slight time delay.
● To ensure that the parking aid works prop-
erly, the sensors must be kept clean and free
of ice and snow. Rear parking aid*
The rear parking aid is an audible assistant. Description
There are sensors integrated in the rear
bumper. When the sensors detect an obsta-
cle, you are alerted by audible warnings.
Make sure that the sensors are not covered
by adhesives, residues and the like, given
that this could affect the system operation.
Cleaning instructions
››› page 185.
The approximate measurement range of the
sensors is:
rearside0.90 m
centre1.60 m As you approach the obstacle, the time inter-
val between the audible warnings will be re-
duced. When you reach around 0.30 m the
warning will be constant: Do not continue to
move forward (or backward)

Connect
ors
Your vehicle is fitted with a 13-pin connector
for the electrical connection between the
trailer and the vehicle.
If the trailer has a 7-pin plug you will need to
u se an a

dapter cable. It is available at any
Technical Service.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If
you do not load the trailer up to the maxi-
mum permitted trailer weight, you can then
climb correspondingly steeper slopes.
The maximum trailer weights listed are only applicable for
altitudes up to 1000 m above
sea level. With increasing altitude the engine
power and therefore the vehicle climbing
ability are impaired because of the reduced
air density. The maximum trailer weight has »

to be reduced accordingly. The weight of the
vehicle and trailer combination must be re-
duced by 10% for every further 1000 m (or
part thereof). The gross combination weight
is the actual weight of the laden vehicle plus
the actual weight of the laden trailer. When
possible, operate the trailer with the maxi-
mum permitted drawbar load on the ball joint
of the t
owing bracket, but do not exceed the
specified limit.
The figures for trailer weights
and drawbar
loads that are given on the data plate of the
to
wing bracket are for certification purposes
only. The correct figures for your specific
model, which may be lower than these fig-
ures for the towing bracket, are given in the
vehicle documentation or in ››› chapter Tech-
nical Data .
Distributing the load
Distribute loads in the trailer so that heavy
objects are as near to the axle as possible.
Loads carried in the trailer must be secured
to prevent them moving.
Tyre pressure
Set tyre pressure to the maximum permissi-
ble pressure shown on the sticker on the in-
side of the fuel tank flap. Set the tyre pres-
sure of the trailer tyres in accordance with the
trailer manufacturer's recommendations. Exterior mirrors
Check whether you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors
to give sufficient vision to the rear.
Tow rope
Always use a cable between the vehicle and
the trailer
››› page 178.
Tr
ailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 178. WARNING
Never transport people in a trailer. This could
result in fatal accidents. Note
● Towing a trailer places additional demands
on the vehicle. We recommend additional
services between the normal inspection inter-
vals if the vehicle is used frequently for tow-
ing a trailer.
● Find out whether special regulations apply
to towing a trailer in your country. Hitching and connecting the trailer

Operation
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing . Never try to stop the “snaking” by in-
c r
easing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gen
tly at
first and then, firmly. This will prevent the
jerking that can be caused by locking of trail-
er wheels. Select a low gear in due course
before going down a steep downhill. This en-
ables you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge ››› page 71.
Electronic stability control*
The ESC* system helps to stabilise the trailer
in case of skidding or rocking. Retrofitting a towing bracket*

●
Driving with a trailer involves an extra effort
for the vehicle. Therefore, before fitting a
towing bracket, please contact a Technical
Service to check whether your cooling system
needs modification.
● The legal requirements in your country
must be observed (e.g. the fitting of a sepa-
rate control lamp).
● Certain vehicle components, e.g. the rear
bumper, must be removed and reinstalled.
The towing bracket securing bolts must be

tightened using a torque wrench, and a pow-
er socket must be connected to the vehicle
electrical system. This requires specialised
knowledge and tools.
● Figures in the illustration show the eleva-
tion value and the attachment points which
must be considered if you are retrofitting a
towing bracket. WARNING
The towing brackets should be fitted at a spe-
cialised workshop.
● If the towing bracket is incorrectly instal-
led, there is a serious danger of accident.
● For your own safety, please observe the tow
bracket manufacturer's instructions. CAUTION
● If the power socket is incorrectly installed,
this could cause damage to the vehicle elec-
trical system. Note
● SEAT recommends that the towing hooks
be fitted at a specialised workshop. Consult
your SEAT dealer in case additional modifica-
tions to your vehicle are necessary.
● Due to the specific design of the exhaust,
the fitting of a conventional towing hook is
not recommended for some sportier versions.
