DRIVER SUPPORT
Other Adaptive Cruise Control
(ACC) functions
ACC has several supplementary functions:
•
Changing target vehicles
•
Automatic standby mode when changing tar-
gets
•
Auto-hold brake function
•
Deactivation of the auto-hold brake function
•
Automatically setting the parking brake
Changing target vehicles
If the target vehicle turns suddenly, there may be a sta-
tionary vehicle ahead
When ACC is actively following another vehicle at
speeds under 20 mph (30 km/h) and changes
targets from a moving vehicle to a stationary one,
the system will brake for the stationary vehicle.
260
WARNING
If ACC changes targets from a moving vehicle
to a stationary one at speeds above 20 mph
(30 km/h), the system will not react to the
stationary vehicle and will accelerate to the
previously set speed.
The driver must actively apply the brakes to
slow/stop the vehicle.
Automatic standby mode when changing
targets
ACC disengages and goes into standby mode if:
•
your vehicle's speed goes below approx. 3
mph (5 km/h) and ACC cannot determine if
the target object is a stationary vehicle or
some other type of object such as a speed
bump, etc
•
the vehicle's speed goes below approx.
3 mph (5 km/h) and the vehicle ahead
changes lanes or turns so that ACC no
longer has a target vehicle to follow
Auto-hold brake function
In slow-moving, stop-and-go traffic or when stop-
ped at a traffic light, driving will resume automati-
cally if the vehicle is not stopped for more than
approx. 3 seconds. If it takes more than
3 seconds for the vehicle ahead to begin moving
again, ACC will go into standby mode and the
auto-hold brake function will activate.
–
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.
