Introduction
The Adaptive Cruise Control(ACC) maintains a speed selected by the driver. If the vehicle approaches a vehicle in
front, the ACC automatically adapts the speed so that a distance you have selected is maintained.
Does my vehicle have the ACC function?
The vehicle is equipped withACC
if you can adjust settings for ACC in the Assist systems menu in the Infotainment system. (→ Vehicle settings menu).
Speed range
You can set a speed between 30 km/h(20 mph) and 210 km/h (130 mph). This speed range may differ in certain
countries.
Driving with Adaptive Cruise Control
You can override the ACC at any time. Control will be cancelled if you brake. If you accelerate, the system will be
interrupted for the duration of the acceleration process and will then continue again.
Control by the ACC is less dynamic when towing a trailer (→ Trailer towing).
Driver intervention prompt
The ACC will send a message to the instrument cluster telling you to apply the brake if the ACC's automatic
deceleration is insufficient, or if the system limits are reached. In addition, the red warning lamp lights up and
an acoustic warning is given. Take control of the vehicle and be prepared to apply the brakes!
Radar sensor
ACC detects driving situations by means of the radar sensor at the front of the vehicle. The range of the radar sensor
is up to approximately 120 m (around 400 ft).
WARNING
The intelligent technology used in the ACC cannot overcome the laws of physics, and functions only within the
limits of the system. Never let the extra convenience tempt you into taking safety risks when driving. Careless or
unintentional use of the Adaptive Cruise Control (ACC) can cause accidents and lead to serious injury. The system is
not a substitute for the full concentration of the driver.
● Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic conditions.
● Never use the ACC in poor visibility, on steep or winding roads, or on slippery road surfaces e.g. due to snow, ice,
wet roads, loose chippings, or on flooded roads.
● Never use the ACC off-road or on non-surfaced roads. The ACC is designed for use on surfaced roads only.
● Take control of the vehicle immediately if a driver intervention prompt appears on the instrument cluster display
or if the ACC does not reduce the speed sufficiently.
● Apply the brakes if the vehicle starts rolling unintentionally, e.g. after a driver intervention prompt.
● Be prepared to control the speed yourself at all times.
