152 STARTING AND OPERATING
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 pres-
sure 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 stand-
still (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 above 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
important 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.
Do not remove any screws from the sensor.
Doing so could cause an ACC system
malfunction or failure and require a sensor
realignment.
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.
