Automatic standby mode when ACC
changes target vehicles
If the vehicle ahead turns suddenly, there may be a sta-
tionary 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 vehi-
cle 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
•
The stability system is put in Sport mode
(see Stability system – operation (p. 167))
•
ACC has kept the vehicle at a standstill for
more than 2 minutes
•
The engine has been switched off
•
The brakes have overheated
