The adaptive cruise control (ACC) i
s
an e
xten-
sion of the normal cruise control system
(CCS) ›››
.
The A
C
C
function allows the driver to program
a cruise speed of between 30 and 210 km/h
(18 and 150 mph) and to select the distance
required with regard to the vehicle in front.
The ACC will adapt the vehicle's cruise speed
at all times, maintaining a safe distance with
the vehicle in front based on its speed.
When driving behind another vehicle, the
ACC function reduces speed until it is the
same as that of the vehicle ahead and main-
tains the set distance between the vehicles.
If the vehicle ahead accelerates, the adaptive
cruise control also accelerates, going no
higher than the target speed programmed.
If the vehicle is equipped with automatic
gearbox, the ACC can brake the vehicle until
it stops completely if a vehicle in front of it
stops.
The distance programmed should be in-
creased when the road surface is wet.
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 223.
WARNING
The intelligent technology in the ACC cannot
over
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
vehicle 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 roads, with several bends or in slip-
pery circumstances such as snow, ice, rain or
loose gravel, or on flooded roads.
