Information system Introduction With the ignition switched on, it is possible
to read the different functions of the display
by scrolling through the menus.
In vehicles with multifunction steering wheel,
the multifunction display can only be operat-
ed with the steering wheel buttons.
The number of menus displayed on the in-
strument panel will vary according to the ve-
hicle electronics and equipment.
A specialised workshop will be able to pro-
gramme or modify additional functions, ac-
cording to the vehicle equipment. SEAT rec-
ommends visiting a SEAT Official Service.
Some menu options can only be read when
the vehicle is at a standstill.
As long as a priority 1 warning is displayed, it
will not be possible to read the menus. Some
warning messages can be confirmed and
made to disappear with the windscreen wiper
lever button or the multifunction steering
wheel button.
The information system also provides the fol-
lowing information and displays (depending
on the vehicle's equipment):Driving data

● Inc orr

ect use of the electric windows can
result in injury.
● Never close the rear lid without observing
and ensuring it is clear, to do otherwise could
cause serious injury to you and third parties.
Make sure that no one is in the path of a win-
dow.
● The engine may accidentally be started and
be out of control.
● If the ignition is switched on, the electric
equipment could be activated with risk of in-
jury, for example, in the electric windows.
● The doors can be locked using the remote
control key. This could become an obstacle
for assistance in an emergency situation. ●
Always take the key with you when you
leave the vehicle.
● The electric windows will work until the ig-
nition has been switched off and one of the
front doors has been opened.
● If necessary, use the safety switch to disa-
ble the rear electric windows. Make sure that
they have been disabled. Note
If the window is not able to close because it
is stiff or because of an obstruction, the win-
dow will automatically open again
››› page 91
. If this happens, check why the
w indo

w could not be closed before attempt-
ing to close it again. Roll-back function
The roll-back function reduces the risk of in-
jury when the electric windows close.
● If a window is obstructed when closing au-
tomatically, the window stops at this point
and lowers immediately ››› .
● Next, check why the window does not close
before attempting it again.
● If you try within the following 10 seconds
and the window closes again with difficulty
or there is an obstruction, the automatic clos-
ing will stop working for 10 seconds. ●
If the window is still obstructed, the win-
dow will stop at this point.
● If there is no obvious reason why the win-
dow cannot be closed, try to close it again by
pulling the tab within ten seconds. The win-
dow closes with maximum force. The roll-
back function is now deactivated.
● If more than 10 seconds pass, the window
will open fully when you operate one of the
buttons. One-touch closing is reactivated. WARNING
Observe the safety warnings ››› in Opening
and closing of the electric windows* on
page 91.
● The r o
ll-back function does not prevent fin-
gers or other parts of the body getting

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*

Air conditioning
● 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. Special Characteristics
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 the engine, any residual humid-
ity in the air conditioner could mist over the
windscreen. Switch on the defrost function as
soon as possible to clear the windscreen of
condensation. Air vents
Fig. 140
On the dash panel: air vents Air vents
To ensure proper heating, cooling and venti-
lation in the vehicle interior, air vents
››› Fig. 140 1 should remain open.
● Turn the corresponding thumbwheel (de-
tail) in the required direction to open and
close the air vents. When the thumbwheel is in the

position, the corresponding air vent
i

s closed.
● Change the air direction using the ventila-
tion grille lever.
There are other additional, non-adjustable air
vents in the dash panel 2 , in the footwell
and in the rear area of the interior. Note
Food, medicine and other heat or cold sensi-
tive objects should never be placed in front of
the air outlets as they may be damaged or
made unsuitable for use by the air coming
from the air vents. 127
