ADAPTIVE CRUISE
CONTROL (ACC)
If your vehicle is equipped with Adaptive
Cruise Control, the controls operate exactly
the same as the speed control with only a
couple of differences. With this option you
can set a specified distance you would like to
maintain between you and the vehicle in front
of you.
165

If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or acceleration
automatically to maintain a preset following
distance, while matching the speed of the
vehicle ahead.If the sensor does not detect a vehicle ahead
of you, ACC will maintain a fixed set speed.

and release. The instrument cluster display
will show the set speed.
If the system is set when the vehicle speed is
below 19 mph (30 km/h), the set speed shall
be defaulted to 19 mph (30 km/h). If the
system is set when the vehicle speed is above
19 mph (30 km/h), the set speed shall be the
current speed of the vehicle.
NOTE:
ACC cannot be set if there is a stationary
vehicle in front of your vehicle in close prox-
imity.Remove your foot from the accelerator pedal.
If you do not, the vehicle may continue to
accelerate beyond the set speed. If this oc-
curs:
• The message “DRIVER OVERRIDE” will
appear in the instrument cluster display.
• The system will not be controlling the dis-
tance between your vehicle and the vehicle
ahead. The vehicle speed will only be de-
termined by the position of the accelerator
pedal.

can be increased or decreased.
NOTE:
• When you override and push the SET(+)
button or SET(-)buttons, the new set
speed will be the current speed of the
vehicle.
• When you use the SET(-)button to decel-
erate, if the engine’s braking power does
not slow the vehicle sufficiently to reach
the set speed, the brake system will auto-
matically slow the vehicle.Adaptive Cruise Switches

ACC Operation At Stop
If the ACC system brings your vehicle to a
standstill while following a target vehicle, if
the target vehicle starts moving within two
seconds of your vehicle coming to a stand-
still, your vehicle will resume motion without
the need for any driver action.
If the target vehicle does not start moving
within two seconds of your vehicle coming to
a standstill, the ACC with Stop system will
cancel and the brakes will release. A cancel
message will display on the instrument clus-
ter display and produce a warning chime.
Driver intervention will be required at this
moment.
While ACC with Stop is holding your vehicle
at a standstill, if the driver seatbelt is un-
buckled or the driver door is opened, the ACC
with Stop system will cancel and the brakes
will release. A cancel message will display on
the instrument cluster display and produce a
warning chime. Driver intervention will be
required at this moment.
WARNING!
When the ACC system is resumed, the
driver must ensure that there are no pedes-
trians, vehicles or objects in the path of
the vehicle. Failure to follow these warn-
ings can result in a collision and death or
serious personal injury.
Changing Modes
If desired, the Adaptive Cruise Control mode
can be turned off and the system can be
operated as a Normal (Fixed Speed) Cruise
Control mode. When in the Normal (Fixed
Speed) Cruise Control mode the distance
setting feature will be disabled and the sys-
tem will maintain the speed you set.

WARNING!
Adaptive Cruise Control (ACC) is a conve-
nience system. It is not a substitute for
active driving involvement. It is always the
driver’s responsibility to be attentive of
road, traffic, and weather conditions, ve-
hicle speed, distance to the vehicle ahead;
and, most importantly, brake operation to
ensure safe operation of the vehicle under
all road conditions. Your complete atten-
tion is always required while driving to
maintain safe control of your vehicle. Fail-
ure to follow these warnings can result in a
collision and death or serious personal
injury.
The ACC system:
• Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).
• Cannot take street, traffic, and weather
conditions into account, and may be
