ACC - Adaptive Cruise Con-
trol
Introduction
Adaptive Cruise Control (ACC) maintains a
constant speed set by the driver. When ap-
proaching another vehicle in front, the ACC de-
tects it and adapts the speed automatically,
maintaining a distance set by the driver.
Does my vehicle have ACC?
Your vehicle has ACC if it has the ACC func-
tion buttons on the multifunction steering wheel
›››page84, or if it has the configuration menu
in the infotainment system.
Speed range
ACC regulates at speeds between 30 and
210km/h (20 and 130mph).
If the vehicle is fitted with an automatic gear-
box, the ACC can bring the vehicle to a stand-
still if a vehicle in front of it stops.
If your vehicle is fitted with a manual gearbox,
you must pay attention to speed and gear
changes. The ACC is deactivated if the speed is
too low (less than 30 km/h) of the engine RPM
is too low or high.
Driving with ACC
You can override the ACC at any time. Braking
interrupts the ACC. If you accelerate, regulation
is interrupted during acceleration and then re-
sumed.
Driver intervention prompt
ACC is subject to certain limitations inher-
ent to the system. This means that the
driver will have to control the speed and
distance from other vehicles in certain sit-
uations. In this case, the instrument cluster
display will tell you to intervene by ap-
plying the brake, and an audio warning will
be played.
Radar sensors
The ACC uses the front radar technology. Read
its maintenance instructions and information
about its limitations ›››page137.
