ted under the rear bumper.
● Switch the ignition off.
● Stand in front of the rear bumper, in the
middle.
● W

ith a brisk movement, bring your foot and
lower l

The rear lid can be closed with another foot
movement similar to the opening one (provi-
ded a valid vehicle key is in the proximity of
the rear lid).
When closed, the rear lid automatically locks
if the vehicle has been locked beforehand
and there is no valid key inside. While the rear lid is in motion (either opening
or clos

ing), it can be stopped with another
foot movement similar to the opening one
(provided a valid vehicle key is in the proxim-
ity of the rear lid).
The Easy Open feature is not available or only
has limited availability in the following situa-
tions (examples):
● If the rear bumper is very dirty.
● If the rear bumper is wet with salt water,
e.g. aft
er having driven on gritted roads.
● If the electrical unlocking tow hitch is not
cov
ered.
● If the vehicle has been equipped at a later
time with a to
w bracket.
In the event of heavy rain, the Easy Open fea-
ture may take a little longer to open the boot
or may deactivate automatically, to avoid the
boot opening by accident, e.g. because of
the running water.

order to enable engine ignition, the  button
on the key inside the vehicle needs to be
pressed.
Automatically disabling sensors
If the vehicle is not locked or unlocked for a
long period of time, the proximity sensors on
the passenger doors are automatically disa-
bled.
If one of the sensor surfaces on the door han-
dles is often activated in an unusual manner
with the vehicle locked (e.g. by the branches
of a bush rubbing against it), all proximity
sensors are disabled for a certain period of
time.
Sensors will again be enabled:
● After a time.
● OR: if the vehicle is unlocked with the 
butt
on on the key.
● OR: if the boot is opened.
● OR: if

the vehicle is unlocked manually with

Air conditioning
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
use the air rec
irculation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● To r ep

lace the pollen filter, always visit a
service centre.
● 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-
cia
list knowledge and special tools. SEAT rec-
ommends visiting a SEAT Official Service. Note
● When the coo lin

g 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-
fro s

t windows as quickly as possible is only
available when the engine has reached its

running and fan is switched on.
The air conditioner operates most effectively
with the windows and the panoramic sliding
sunroof closed. However, if the vehicle has
heated up after standing in the sun for some
time, the air inside can be cooled more quick-
ly by opening the windows and the panoram-
ic sliding sunroof briefly.

The cooling system cannot be activated
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-
prox
imately +3°C (+38°F).
● The air conditioner compressor has been
temporari
ly switched off because the engine
coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner chec
ked by a specialised work-
shop. Special Characteristics
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! Note
After starting the engine, any residual humid-
ity in the air c onditioner c

ould mist over the
windscreen. Switch on the defrost function as
soon as possible to clear the windscreen of
condensation. 173

Auxiliary heater (additional
he at
er)*
Intr
oduction The auxiliary heater runs on fuel from the ve-
hicl
e's

tank and can be used while you are
driving and when the vehicle is stationary.
The auxiliary heater can be switched on using
the fast heating button of the air condition-
ing controls, with the remote control or by
previously programming a departure time in
the auxiliary heater menu of the infotainment
system.
In winter, with the auxiliary heater switched
on, you can defog the windscreen and leave
it free of ice and snow (if it is a thin layer) be-
fore you start driving.
If the outside temperature is very high, the
vehicle interior can be ventilated with the en-
gine off using the auxiliary heater. WARNING
Swallowing a battery with a 20 mm diameter
or any other b

utton battery can cause serious
and even fatal injuries within a very short
time.
● Always keep the remote control, keyrings
with batt
eries, the spare batteries, button
batteries and all other batteries over 20 mm
out of reach of children. ●
If y

ou suspect that someone may have
swallowed a battery, seek immediate medical
attention. WARNING
The auxiliary heater exhaust fumes contain
c arbon mono x

ide, an odourless and colour-
less toxic gas. Carbon monoxide can cause
people to lose consciousness. It can also
cause death.
● Never switch on the auxiliary heater or
leav
e it running in enclosed spaces or areas
with no ventilation.
● Never programme the auxiliary heater so
that it
switches itself on and is running in an
enclosed space or an area with no ventila-
tion. WARNING
The components of the auxiliary heater are
extr emely

hot and could cause a fire.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
easily flammable materials that might be be-
low the vehicle, such as dried grass. CAUTION
Never place food, medicines or other temper-
atur e-

sensitive objects close to the air vents.
Food, medicines and other objects sensitive
to heat or cold may be damaged or made un- suitable for use by the air coming from the
vent
s. Note
After switching the engine on with a 12-volt
b att er

y that is heavily discharged or newly
changed or after a jump start some system
settings (such as the time, the date, the per-
sonalised comfort settings and the program-
ming) might be altered or deleted. Check and

Operation
WARNING
Never programme the auxiliary heater so that
it sw it
ches itself on and is running in an en-
closed space or an area with no ventilation.
The auxiliary heater exhaust fumes contain
carbon monoxide, an odourless and colour-
less toxic gas. Carbon monoxide can cause
people to lose consciousness. It can also
cause death. Operating instructions
The auxiliary heater exhaust system located
belo
w the
v

ehicle must be kept clear of snow,
mud and other objects. The exhaust fumes
must be able to exit freely. The emissions
generated by the auxiliary heater are re-
moved via an exhaust pipe fitted underneath
the vehicle.
On heating the vehicle interior, depending on
the outside temperature, the warm air is first
directed at the windscreen and then to the
rest of the vehicle interior through the air
vents. Directing the diffusers – towards the
windows for example – can affect air distribu-
tion.
When will the auxiliary heater not be activa-
ted?
● The auxiliary heater requires about as
much po w

er as the dipped beam headlights.
If the 12-volt battery charge is too low, the auxiliary heater switches off automatically
and cannot
be sw

itched on. This avoids prob-
lems when starting the engine.
● The heating must be activated every time
you want
to set off. Similarly, the departure
time must reactivate each time.
● The control lamp  (fuel l
evel indicator)
lights up. Note
● Noise s

will be heard while the auxiliary
heater is running.
● When the air humidity is high and the in-
side temper
ature low, condensation from the
heating and ventilating system may evapo-
rate when the auxiliary heater is switched on.
In this case, steam may be released from un-
derneath the vehicle. This does not mean
that there is a vehicle malfunction.
● If the vehicle is tilted, e.g. if parked on a
slope, the operation of
the auxiliary heater
may be restricted if the fuel tank level is low
(just above the reserve level).
● If the auxiliary heater is used a number of
times f
or a long period of time, the 12-volt
battery will lose its charge. To recharge the
battery, the vehicle must be driven for a num-
ber of kilometres from time to time. As a
guideline: The journey should last approxi-
mately as long as the heater was connected.
● At temperatures below +5°C (+41°F), the
auxili
ary heater may switch itself on automat-
ically when the engine is switched on. The auxiliary heater is switched off again after a
cer
t

ain time.180
