WARNING
When Adaptive Cruise Control follows another
vehicle at speeds over approx. 30 km/h
(20 mph) and changes target vehicle – from a
moving vehicle to a stationary one – Adaptive
Cruise Control will ignore the stationary vehi-
cle and instead accelerate to the stored
speed.
•
The driver must then intervene and apply
the brakes.
Automatic standby mode when switching
targets
Adaptive Cruise Control will be disabled and go
into standby mode:
•
if your vehicle's speed goes below 5 km/h
(3 mph) and Adaptive Cruise Control cannot
determine if the target object is a stationary
vehicle or another object, e.g. a speed bump.
•
if your vehicle's speed goes under 5 km/h
(3 mph) and the vehicle ahead turns so that
Adaptive Cruise Control no longer has a vehi-
cle to follow.

Automatic braking with Adaptive
Cruise Control
The Adaptive cruise control (ACC
52
) has a spe-
cial brake function in slow traffic and while sta-
tionary.
Braking function in slow traffic and at a
standstill
In slow-moving, stop-and-go traffic or when stop-
ped at a traffic light, driving will resume automati-
cally if the vehicle is stopped for less than
approx. 3 seconds. If it takes more than 3 sec-
onds for the vehicle ahead to begin moving again,
Adaptive Cruise Control will go into standby
mode and the Auto-hold brake function will acti-
vate.
–
Adaptive Cruise Control can be reactivated in
one of the following ways:
•
Pressing the
button on the steering
wheel keypad.
•
Pressing the accelerator pedal.
> Adaptive Cruise Control will resume fol-
lowing the vehicle ahead if it begins to
move within approx. 6 seconds.
NOTE
ACC can keep the vehicle stationary for no
more than 5 minutes – after that time the
parking brake is applied and Adaptive Cruise
Control is deactivated.
The parking brake must be released before
Adaptive Cruise Control 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 Adaptive
Cruise Control will go into standby mode. This
means that the brakes will be released and the
vehicle could begin to roll. The driver must
actively apply the brakes to keep the vehicle sta-
tionary.
This can occur if:
•
the driver depresses the brake pedal
•
the parking brake is applied
•
the gear selector is moved to the
P
,
N
or
R
positions
•
the driver puts Adaptive Cruise Control in
standby mode.
Auto Activate Parking Brake
In certain situations, the parking brake will be
applied to keep the vehicle at a standstill.
