The essentials
Driver information System Intr oduction With the ignition switched on, it is possible
to r
e
ad 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
››› page 41. Some warning messages can
be confirmed and made to disappear with the
windscreen wiper lever button or the multi-
function steering wheel button.
The information system also provides the fol-
lowing information and displays (depending
on the vehicle's equipment):
