WARNING
At speeds above 20 mph (30 km/h), if ACC
changes targets from a moving vehicle to a
stationary one, 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.
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.
