– The driver will then have to reactivate ACC in
one of the following ways:
•
Press the button on the left-side
steering wheel keypad.
•
Press the accelerator pedal.
> ACC will resume following the vehicle
ahead (target vehicle) if it begins to move
within approx. 6 seconds.
NOTE
ACC can keep the vehicle at a standstill for
up to 5 minutes, after which the parking brake
will be set and ACC will go into standby
mode.
The parking brake has to be released before
ACC can be reactivated.
Deactivation of the auto-hold brake function
In certain situations, auto-hold will be deactivated
when the vehicle is at a standstill and ACC will go
into standby mode.
This means that the brakes will be released and
the vehicle can begin to roll.
The driver must actively apply the brakes to keep
the vehicle at a standstill.
This can occur in the following situations:
•
the driver presses the brake pedal
•
the parking brake is set
•
the gear selector is moved to the
P
,
N
or
R
positions
•
the driver puts ACC in standby mode.
Automatically setting the parking brake
In certain situations, the parking brake is set
automatically to help keep the vehicle at a stand-
still.
This occurs if ACC keeps the vehicle at a stand-
still with the brakes and:
•
the driver unbuckles the seat belt or opens
the door
•
ACC has kept the vehicle at a standstill for
more than approx. 5 minutes
•
the brakes overheat
•
the engine is turned off.

Adaptive Cruise Control (ACC) -
limitations
Adaptive Cruise Control (ACC) functionality may
be limited in certain situations.
Steep roads and/or heavy loads
Adaptive Cruise Control is primarily intended for
use on relatively level roads. The function may not
be able to maintain the correct time interval to
the vehicle ahead when driving down steep hills.
The driver should be attentive and prepared to
apply the brakes in these situations.
Do not use Adaptive Cruise Control when the
vehicle is transporting a heavy load or if it is tow-
ing a trailer.
Additional information
The
Off Road
drive mode cannot be selected if
Adaptive Cruise Control is activated.
NOTE
This function uses the vehicle's camera and
radar sensor, which have certain general limi-
tations. See the articles "Camera limitations"
and "Radar sensor limitations" for additional
information.
