STARTING AND OPERATING 137
The vehicle will then maintain the set distance until:
The vehicle ahead accelerates to a speed above the
set speed.
The vehicle ahead moves out of your lane or view of the
sensor.
The distance setting is changed.
The system disengages
Ú page 134.
The maximum braking applied by ACC is limited; however,
the driver can always apply the brakes manually, if
necessary.
NOTE:
The brake lights will illuminate whenever the ACC system
applies the brakes.
A Proximity Warning will alert the driver if ACC predicts that
its maximum braking level is not sufficient to maintain the
set distance. If this occurs, a visual alert “BRAKE!” will
flash in the instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity.
NOTE:
The “BRAKE!” screen in the instrument cluster display is a
warning for the driver to take action and does not neces-
sarily mean that the Forward Collision Warning system is
applying the brakes autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (ACC) engaged
and following a vehicle, the system will provide an
additional acceleration up to the ACC set speed to assist
in passing the vehicle. This additional acceleration is
triggered when the driver utilizes the left turn signal and
will only be active when passing on the left side.
ACC Operation At Stop
If the ACC system brings your vehicle to a standstill while
following a vehicle ahead, your vehicle will resume motion,
without any driver interaction, if the vehicle ahead starts
moving within two seconds of your vehicle coming to a
standstill.
If the vehicle in front does not start moving within two
seconds of your vehicle coming to a standstill, the driver
will either have to push the RES (resume) button, or apply
the accelerator pedal to reengage the ACC to the existing
set speed.
NOTE:
If your vehicle is at a standstill for longer than two
seconds, the system will hold brake pressure for up to
10 minutes. If no driver action is taken after the
10 minutes, the Electric Park Brake will be applied and
the ACC system will cancel.
While ACC is holding your vehicle at a standstill (or the
vehicle is traveling below 3 mph (5 km/h), and the
driver seat belt is unbuckled or the driver door is
opened, the Electric Park Brake will be applied and the
ACC system will cancel.
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC Unavailable Wipe Front Radar Sensor” warning
will display and a chime will sound when conditions
temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud, dirt
or ice. In these cases, the instrument cluster display will
display the warning message and the system will
deactivate.
This message can sometimes be displayed while driving in
highly reflective areas (i.e. ice and snow, or tunnels with
reflective tiles). The ACC system will recover after the
vehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:
If the “ACC Unavailable Wipe Front Radar Sensor” warning
is active, Fixed Speed Cruise Control is still available.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the center of the
vehicle behind the lower grille.
WARNING!
When the ACC system is resumed, the driver must
ensure that there are no pedestrians, vehicles or
objects in the path of the vehicle. Failure to follow these
warnings can result in a collision and death or serious
personal injury.
