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 page 132.
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE:
The brake lights will illuminate whenever the ACC sys-
tem applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to main-
tain 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
necessarily 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 with passing the vehicle. This additional accel-
eration 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.
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.
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 condi-
tions 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 clus-
ter display will display this 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.
To keep the ACC System operating properly, it is impor-
tant to note the following maintenance items:
•
Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
