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 operated with the multifunction steering wheel buttons.
The number of menus displayed on the instrument panel will vary according
to the vehicle electronics and equipment.
A specialised workshop will be able to programme or modify additional
functions, according to the vehicle equipment. SEAT recommends 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 disap-
pear with the windscreen wiper lever button or the multifunction steering
wheel button.

Driver assistance systems
Adaptive cruise control (ACC)*
Introduction
Fig. 129 Detection area
Adaptive cruise control (ACC) is an extension of vehicle cruise control (GRA)
⇒ 
.
The ACC function allows the driver to establish a cruising speed between 30
and 160 km/h (18 and 100 mph), as well as the time distance from the ve-
hicle ahead. The ACC function will adapt to the vehicle's adaptive cruise
speed at all times, maintaining a safety distance from the vehicle ahead.
The ACC function is based on a radar sensor that can measure the distance
to vehicles ahead.
If the vehicle is equipped with automatic gearbox, the ACC may brake it un-
til it stops completely if the vehicle ahead stops.
Request for driver intervention
During driving, the ACC is subject to certain limitations inherent in the sys-
tem. In other words, in certain circumstances the actual driver will have to
control speed and distance with regard to other vehicles. In this case, the instrument panel display
will tell the driver to intervene by
pressing the brake pedal, and a warning sound will go off ⇒ page 191.
Additional information and warnings:
● SEAT information system ⇒ page 73
● Easy Connect system ⇒ page 79
● Cruise control system (CCS) ⇒ page 184
● Front Assist ⇒ page 202
● Lane Assist ⇒ page 207
● Accessories, parts replacement, repairs and modifications ⇒ page 272
WARNING
The intelligent technology in the ACC cannot overcome the system's own
limitations or change the laws of physics. If used negligently or uninten-
tionally it may cause a serious accident and serious injury. The system is
not a replacement for driver awareness.
● Always adapt speed and safety distance to the vehicle ahead accord-
ing to visibility, weather, road and traffic conditions.
● Do not use the ACC in conditions of poor visibility, on steep roads,
with several bends or in slippery circumstances such as snow, ice, rain or
loose gravel or on flooded roads.
● Never use the ACC when driving off-road or on unpaved roads. The
ACC has only been designed for use on paved roads.
● The ACC does not react on approaching a stationary obstacle, such as
the end of a traffic jam or a broken-down vehicle or a vehicle stopped at
traffic lights.
● The ACC does not react during driving to people or animals or vehi-
cles changing lane or approaching in the opposite direction in the same
lane.
● If the ACC does not reduce speed enough, apply the foot brake imme-
diately. 

198Driver assistance systems
Switching off adaptive cruise control (ACC) temporarily in
certain situations
The adaptive cruise control (ACC) should be switched off in the following sit-
uations due to the system's limitations ⇒ :
● When changing lanes, on tight bends, at roundabouts, in the accelera-
tion and deceleration lanes on motorways or in road work stretches to pre-
vent involuntary acceleration to reach the stored speed.
● When going through a tunnel, as its operation might be affected.
● On roads with several lanes when other vehicles are driving more slowly
in the overtaking lane. In this case, vehicles driving more slowly in the other
lanes would be overtaken on the right.
● In heavy rain, snow or thick mist, as it might not detect the vehicle
ahead or in certain circumstances it might not detect the vehicle altogether.
WARNING
If the adaptive cruise control is not switched off in the aforementioned
situations, accidents and serious injuries may be caused.
● The ACC should always be switched off in critical situations.
Note
Failure to switch off the ACC in the situations may be an offence. 
