ADAPTIVE CRUISE CONTROL (ACC) (IF EQUIPPED)
Adaptive cruise control (ACC) is much like speed control, only this
system is designed to automatically adjust your speed to maintain a
proper distance between you and the vehicle in front of you in the same
lane. The driver can select from one of four GAP settings, the controls
are located on the steering wheel.
At startup, the system sets the gap
to the last selected setting. Once
activated, the driver can deactivate
the system at any time by pressing
the brake pedal, pressing the
steering wheel ON/OFF control or pressing the RES/CNCL control. In
addition, the driver can temporarily increase the vehicle speed above the
current speed by manually pressing on the accelerator pedal.
WARNING:Always pay close attention to changing road
conditions, especially when using adaptive cruise control.
Adaptive cruise control cannot replace attentive driving. Failing to
follow any of the warnings below or failing to pay attention to the road
may result in a collision, serious injury or death.
WARNING:Adaptive cruise control is not a collision warning or
avoidance system. Additionally, adaptive cruise control will not
detect:
•Stationary or slow moving vehicles below 6 mph (10 km/h).
•Pedestrians or objects in the roadway.
•Oncoming vehicles in the same lane.
WARNING:Do not use the adaptive cruise control when
entering or leaving a highway, in heavy traffic or on roads that
are winding, slippery or unpaved.
WARNING:Do not use in poor visibility, specifically fog, rain,
spray or snow.

Following a vehicle
WARNING:When following a vehicle in front of you, the vehicle
will not decelerate automatically to a stop, nor will the vehicle
always decelerate quickly enough to avoid a collision without driver
intervention. Always apply the brakes when necessary. Failing to do so
may result in a collision, serious injury or death.
When a vehicle ahead of you enters the same lane or a slower vehicle is
ahead in the same lane, the vehicle speed will adjust automatically to
maintain a preset gap distance. The distance setting is adjustable, refer
toSetting the gap distancein this section.
The lead vehicle graphic will be illuminated.
The vehicle will maintain a constant distance between the vehicle ahead
until:
•The vehicle in front of you accelerates to a speed above the set speed.
•The vehicle in front of you moves out of your lane or out of view.
•The vehicle speed falls below 16 mph (26 km/h).
•A new gap distance is set.
The vehicle brakes will be automatically applied to slow the vehicle to
maintain a safe distance between the vehicle in front. The maximum
braking which is applied by the ACC system is limited and can be
overridden by the driver applying the brakes.
If the ACC system predicts that its
maximum braking level will not be
sufficient, an audible warning will
sound while the ACC continues to
brake. This is accompanied by a
heads-up display; a red warning bar
illuminating on the windshield. The driver should takeimmediate
action.
Note:The brakes may emit a sound when they are being modulated by
the adaptive cruise control system.
WARNING:Adaptive cruise control only warns of vehicles
detected by the radar sensor. In some cases there may be no
warning or the warning may be delayed. The driver should always
apply the brakes when necessary. Failing to do so may result in a
collision, serious injury or death.

Setting the gap distance
The distance between your vehicle
and the vehicle in front of you can
be decreased or increased by
pressing the GAP control up or
down. The selected gap will be
displayed in the message center as shown by the bars in the graphic.
Four gap distance settings are available.

Each time the vehicle is restarted, the last chosen gap for the current
driver will be automatically selected.
Note:It is the driver’s responsibility to select a gap appropriate to the
driving conditions.
Disengaging adaptive cruise control
Press the brake pedal or press CNCL to disengage the adaptive cruise
control. The last set speed will be displayed with a strikethrough.
Disengaging the adaptive cruise control will not erase your previous set
speed.
Overriding adaptive cruise control
WARNING:Whenever the driver is overriding the ACC by
pressing the accelerator pedal, the ACC will not automatically
apply the brakes to maintain separation from any vehicle ahead.
The set speed and gap distance can be overridden by pressing the
accelerator pedal.
When the driver is overriding ACC, the green
ACC light is
illuminated, and the follow vehicle is not displayed in the message
center. When the accelerator is released, the ACC function will operate
again and vehicle speed will decrease to the set speed, or a lower speed
if following a slower vehicle.

Changing the set speed
There are three ways to change the set speed:
•Accelerate or brake to the desired speed and press SET upward and
release.
•Increase or decrease the speed by holding SET upward or downward
until the desired set speed is shown on the message center. The
vehicle speed will gradually change to the selected speed.
•Increase or decrease the speed in increments of 1 mph (2 km/h) by
briefly pressing the SET upward or downward.
The ACC may apply the brakes to slow the vehicle down to the new set
speed. The set speed will display continuously in the message center
while ACC is active.
Resuming the set speed
Press and release RES/CNCL. This will automatically return the vehicle
to the previously set speed. The set speed will display continuously in
the message center while ACC is active.
Note:Resume should only be used if the driver is aware of the set speed
and intends to return to it.
Low speed automatic cancellation
ACC is not functional at vehicle speeds below 16 mph (26 km/h). Once
the vehicle speed drops below 16 mph (26 km/h), an audible alarm will
sound and the automatic braking will be released.
Hilly condition usage
It is recommended that the driver select a lower gear position when ACC
is active in situations such as prolonged downhill driving on steep grades
(i.e., driving in mountainous areas). In these situations, additional engine
braking is needed to reduce the load on the vehicle’s regular brake
system to prevent them from overheating. For more information,
referenceAutomatic transmission operationin theDrivingchapter.
Note:If ACC is applying brakes for an extended period of time, an
audible alarm will sound and ACC will shut down. This is to allow the
brakes to cool down. When the brakes have cooled down, the ACC will
again function normally.
Turning off cruise control
Press OFF to turn off the cruise control.
Note:When you turn off the cruise control or the ignition, your cruise
control set speed memory is erased.

Detection issues
The radar sensor has a limited field of vision. In some situations it may
not detect vehicles at all or detect a vehicle later than expected.
Detection issues can occur:
•When driving on a different line than the vehicle in front.
•With vehicles that edge into your lane. These vehicles can only be
detected once they have moved fully into your lane.

•There may be issues with the detection of vehicles in front when
driving into and coming out of a bend or curve in the road.
In these cases ACC may brake late or unexpectedly. The driver should
stay alert and intervene when necessary.
ACC Not Available
Several conditions exist which can cause ACC to deactivate or prevent
ACC from activating when requested. These conditions include:
•The sensor is blocked, refer toBlocked sensorin this section.
•
Brake temperature is high, refer toHilly condition usagein this section.
•A failure has occurred in the ACC system or related system.
Blocked sensor
If a message regarding a blocked
sensor is displayed, the radar signals
from the sensor have been
obstructed. The sensor is located
behind a fascia cover near the driver
side of the lower grille. When the
radar signals are obstructed, a
vehicle ahead cannot be detected
and the ACC will not function. The
following table lists possible causes
and actions for this message being
displayed.
