04 Driver support
Adaptive Cruise Control (ACC)*

154
* Option/accessory, for more information, see Introduction.
•
The vehicle ahead must be within a rea-
sonable distance (not farther away than
approx. 100 ft/30 meters)
•
The lowest speed that can be selected is
18 mph (30 km/h), although ACC will also
help maintain the set time interval to the
vehicle ahead at lower speeds, including
a complete stop.
During short stops (less than approximately
3 seconds) in slow-moving traffic, your vehi-
cle will begin moving again automatically as
soon as the vehicle ahead begins to move.
If it takes more than 3 seconds for the vehicle
ahead to begin moving, ACC will be automat-
ically go into standby mode.
The driver will then have to reactivate ACC in
one of the following ways:
•
By pressing
•
By accelerating up to at least 3 mph
(4 km/h). ACC will then resume following
the vehicle ahead.
Your vehicle will then resume following the
vehicle ahead at the set time interval.
NOTE
ACC can remain active and keep your
vehicle at a standstill for up to 4 minutes.
After 4 minutes have elapsed, the parking
brake will be engaged and ACC will go into
standby mode.
To reactivate ACC, the driver must release
the parking brake (see page 135).
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 sys-
tem 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 acceler-
ate 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
