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. 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):

Operation
In vehicles that do not have the correspond-
in g menu, thi
s
function can be deactivated in
a specialised workshop. WARNING
Improper or lack of use of the turn signals, or
for g

etting to deactivate them can confuse
other road users. This could result in a seri-
ous accident.
● Always give warning when you are going to
chan
ge lane, overtake or when turning, acti-
vating the turn signal in good time.
● As soon as you have finished changing
lane, ov
ertaking or turning, switch the turn
signal off. WARNING
Incorrect use of the headlights may cause ac-
cident s

and serious injury, as the main beam
may distract or dazzle other drivers. Note
● If the c on

venience turn signals are operat-
ing (three flashes) and the other convenience
turn signals are switched on, the active part
stops flashing and only flashes once in the
new part selected.
● The turn signal only works when the igni-
tion is sw
itched on. The hazard warning
lights also work when the ignition is switch-
ed off. ●
If a tr ai

ler turn signal malfunctions, the
control lamp will stop flashing (trailer turn
signals) and the vehicle turn signal will flash
at double speed.
● The main beam headligh
ts can only be
switched on if the dipped beam headlights
are already on.
● In cold or damp weather conditions, the
headlight
s, tail lights and turn signals may
mist up inside temporarily. This is normal and
in no way effects the useful life of the vehicle
lighting system. Automatic dipped beam control

table on page 2
Main beam assist (Light Assist)
The main beam assist acts within the limits
of the system and depending on environmen-
tal and traffic conditions. Once switched on,
the system is activated as of a speed of
about 60 km/h (37 mph) and is deactivated
below about 30 km/h (18 mph) ››› .
When the sy s
t

em is activated and the camera
detects other vehicles that may be dazzled,
the main beam is automatically switched off.
Otherwise, the main beam is automatically
switched on.

Driver assistance systems
If the vehicle is equipped with automatic
g e
arbo
x, the ACC can brake the vehicle until
it stops completely if a vehicle in front of it
stops.
Driver intervention prompt
During driving, the ACC is subject to certain
limitations inherent in the system. In other
words, in certain circumstances the driver will
have to adjust speed him or herself, as well
as the distance from other vehicles.
In this case, the instrument panel screen will
warn you to intervene by applying the brake
and a warning tone will be heard
››› page 198. WARNING
The intelligent technology in the ACC cannot
ov er

come the system's inherent limitations
or change the laws of physics. If used negli-
gently or involuntarily, it may cause serious
accidents and injuries. The system is not a re-
placement for driver awareness.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit visi-
bility, weather, road and traffic conditions.
● Do not use the ACC when visibility is bad,
on steep r
oads, with several bends or in slip-
pery circumstances such as snow, ice, rain or
loose gravel, or on flooded roads.
● Never use the ACC when driving off-road or
on unpav
ed roads. The ACC has been de-
signed for use on paved roads only. ●
The AC C

does not react on approaching a
fixed obstacle, such as the tail of a traffic
jam, a damaged vehicle or a vehicle stopped
at the traffic lights.
● The ACC only reacts to people if a pedes-
trian monitorin
g system is available. In addi-
tion, the system does not react to animals or
vehicles crossing your path or approaching
head-on down the same lane.
● If the ACC does not reduce speed sufficient-
ly, brak
e the vehicle immediately by applying
the pedal.
● If you are driving using the spare wheel,
the ACC
system could automatically switch
off during the journey. Switch off the system
when starting off.
● If the vehicle continues to move involuntar-
ily af
ter a driver intervention prompt, brake
the vehicle by applying the pedal.
● If the dash panel displays a driv
er interven-
tion prompt, adjust the distance yourself.
● The driver should be ready to accelerate or
brake b
y him/herself at all times. CAUTION
If you have the sensation that the radar sen-
sor is d

amaged, disconnect the ACC. This will
avoid possible damage. If this occurs have it
adjusted.
● Repairs to the radar sensor require special-
ist
knowledge and special tools. SEAT recom-
mends visiting a SEAT dealership for this pur-
pose. Note
● If the A C

C system does not work as descri-
bed in this chapter, do not use it until it has
been checked by a specialised workshop.
SEAT recommends visiting a SEAT dealership
for this purpose.
● Maximum speed with the ACC activated is
limited to 210 km/h (150 mph).
● When the A

CC is switched on, strange
noises
may be heard during automatic brak-
ing cause by the braking system. 197
