Adaptive Cruise Control (ACC)*

160 * Option/accessory, for more information, see Introduction.
Automatic standby mode when ACC
changes target vehicles
If the vehicle ahead turns suddenly, there may be
a stationary vehicle ahead
The following only applies at speeds below
approximately 18 mph (30 km/h):
If ACC changes target vehicles (the vehicle that
the radar sensor has detected) from a moving
vehicle to a stationary one, the system will
apply the brakes in your vehicle.
WARNING
At speeds above 18 mph (30 km/h), ACC
will not react to a stationary vehicle and
apply the brakes but will instead accelerate
to the previously set speed. The driver must
actively apply the brakes to stop the vehicle.
ACC disengages and goes into standby mode
if:
• Your vehicle's speed goes below 10 mph
(15 km/h) and ACC cannot determine if the
target object is a stationary vehicle or some
other type of object such as e.g., a speed
bump.
• Your vehicle's speed goes below 10 mph
(15 km/h) and the vehicle ahead turns so
that ACC no longer has a target vehicle to
follow.
No automatic braking when at a
standstill
In certain situations, ACC will no longer apply
the brakes and go into standby mode while the
vehicle is not moving. This means that the
driver will have to apply the brakes.
This happens if:
• The driver presses the brake pedal
• The parking brake is activated
• The gear selected is moved to P,N or R
• The driver presses the button to put
ACC in standby mode
The parking brake is applied
automatically
In certain situations, ACC will apply the parking
brake in order to continue keeping the vehicle
at a standstill.
This happens if:
• The driver opens the door or takes off
his/her seat belt
• DSTC is put in Sport mode (see page 149)
• ACC has kept the vehicle at a standstill for
more than 2 minutes
• The engine has been switched off
• The brakes have overheated
Turning ACC off completely
• From standby mode, press once.
• From active mode, press twice.
The set speed and time interval are then
cleared from the system's memory and cannot
be resumed by pressing
.
The radar sensor and its limitations
In addition to being used by ACC, the radar
sensor is also used by Distance Alert (see
page 165) and Collision Warning with Full
Auto-brake and Pedestrian Detection (see
page 173). This sensor is designed to detect
cars or larger vehicles driving in the same
direction as your vehicle, in the same lane.
