ACC - Adaptive Cruise
Control
Introduction
Adaptive Cruise Control (ACC) maintains a
constant speed set by the driver. When ap-
proaching another vehicle in front, the ACC
detects 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 function
buttons on the multifunction steering wheel
›››page87, or if it has the conguration menu
in the infotainment system.
Speed range
ACC regulates at speeds between 30 and
210km/h (20 and 130mph).
The ACC can bring the vehicle to a standstill if
a vehicle in front stops.
Driving with ACC
You can override the ACC at any time. Brak-
ing interrupts the ACC. If you accelerate, reg-
ulation is interrupted during acceleration and
then resumed.
Driver intervention prompt
ACC is subject to certain limitations in-
herent 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 clus-
ter display will tell you to intervene by
applying 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 ›››page144.
