Special driving situations
The Adaptive Cruise Control system (ACC) helps maintain an individually stored constant speed
between about 20 mph (30 km/h) and 95 mph (150 km/h) and a previously set distance in time inter-
vals between your vehicle and those in front of you.
ACC uses radar, ultrasonic and video sensors installed on your vehicle. Moving vehicles in front of
yours can be detected within a distance of up to 590 ft (180 m).
The vehicle may be braked, if the situation so requires,
to a standstill
by an
active braking maneu-

Adaptive Cruise Control has system-specified limits. As a driver, you must control the speed and the
distance to other vehicles under some circumstances. If that is necessary, the system requests the
driver to take over using a visual and audible warning.
How does Adaptive Cruise Control (ACC) work?
Adaptive Cruise Control requires you to set the desired speed and distance. Set and adjust the speed
using the lever to the left of the steering column. Set the distance using the sliding switch on top of the
lever.
