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.
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.
Note:The brakes may emit a sound when they are being modulated by
the adaptive cruise control system.
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.
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 from the vehicle in front. The maximum braking
which is applied by the system is limited and can be overridden by the
driver applying the brakes.
If the system predicts that its maximum braking level will not be
sufficient, an audible warning will sound while the system continues to
brake. This is accompanied by a heads-up display; a red warning bar
illuminating on the windshield. The driver should take immediate action.

Setting the Gap Distance
Note:It is the driver’s responsibility to select a gap appropriate to the
driving conditions.
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.
Disengaging Adaptive Cruise Control
Press the brake pedal or press CNCL to disengage the system. The last
set speed will be displayed with a strikethrough.
Disengaging the system 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 the system, the green indicator
light is illuminated, and the follow vehicle is not shown in the
information display. The system will resume operation when you
release the accelerator pedal. The 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 information display. 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 system may apply the brakes to slow the vehicle down to the new
set speed. The set speed will display continuously in the information
display while the system is active.
Resuming the Set Speed
Note:Resume should only be used if the driver is aware of the set speed
and intends to return to it.
Press and release RES/CNCL. The vehicle will return to the previously
set speed. The set speed will display continuously in the information
display while the system is active.
Low Speed Automatic Cancellation
The system is not functional at vehicle speeds below 16 mph (26 km/h).
An audible alarm will sound and the automatic braking will be released if
the vehicle drops below this speed.
Hilly Condition Usage
Note:An audible alarm will sound and the system will shut down if it is
applying brakes for an extended period of time. This allows the brakes to
cool down. The system will function normally again when the brakes
have cooled down.
You should select a lower gear position when the system is active in
situations such as prolonged downhill driving on steep grades (i.e.,
driving in mountainous areas). Additional engine braking is needed in
these situations to reduce the load on the vehicle’s regular brake system
to prevent them from overheating.
Switching Off Adaptive Cruise Control
Note:The set speed memory is erased when you turn off the system.
Press and release OFF or turn off the ignition.

Detection Issues
The radar sensor has a limited field of vision. It may not detect vehicles at
all or detect a vehicle later than expected in some situations. The lead
vehicle graphic will not illuminate if a vehicle is not detected in front of you.
Detection issues can occur:
A. When driving on a different line
than the vehicle in front.
B. With vehicles that edge into your
lane. These vehicles can only be
detected once they have moved fully
into your lane.
C. 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 the system may brake late or unexpectedly. The driver
should stay alert and intervene when necessary.
If the front end of the vehicle is hit or damaged, the radar sensing zone may
be altered causing missed or false vehicle detections. See your authorized
dealer to have the radar checked for proper coverage and operation.
Adaptive Cruise Control Not Available
Several conditions exist which can cause the system to deactivate or prevent
the system from activating when requested. These conditions include:
•a blocked sensor
•high brake temperature
•a failure in the system or a related system.

Cause Action
Swirling water, or snow or ice on
the surface of the road may
interfere with the radar signalsDo not use ACC in these condition
because it may not detect, warn,
or respond to potential collisions.
Desert / remote area with no other
vehicles and no roadside objectsWait a short time or switch to
normal cruise control.
Due to the nature of radar technology, it is possible to get a blockage
warning and not be blocked. This can happen, for example, when driving
in sparse rural or desert environments. A false blocked condition will
either self clear or clear after a key cycle.
Switching to Normal Cruise Control
WARNING:Normal cruise control will not brake due to slower
vehicles. Always be aware of which mode is selected and apply
the brakes when necessary.
You can manually change from adaptive cruise control to normal cruise
control through the information display.
The cruise control indicator light will replace the adaptive
cruise control indicator light if normal cruise control is selected.
The gap setting will not be displayed, the system will not
automatically respond to lead vehicles and automatic braking will not be
activated. The system will default to adaptive cruise control when the
engine is started.

System Settings
The system has three optional setting menus available. To view or adjust
them, select Settings > Vehicle Settings > Driver Assist > Lane Keeping
Sys in the left-hand instrument cluster display using the OK button on
the steering wheel. The last-known selection for each of these settings is
stored by the system. You do not need to readjust your settings each
time you turn on the system.
Mode:This setting allows the driver to select which of the system
features will be enabled and turned on when the button is pressed.
•Alert only – Provides a steering wheel vibration when an unintended
lane departure is detected.
•Aid only – Provides a steering input toward the lane center when an
unintended lane departure is detected.
•Alert + Aid
Sensitivity:This setting affects where in the lane a warning is provided
(e.g. the increased sensitivity setting will move the warning zones in
closer). This setting does not impact the aid mode.
•Normal
•Increased
Intensity:This setting affects the intensity of the steering wheel
vibration used for the alert mode. This setting does not impact the aid
mode.
•Low
•Medium
•High
System Display
When the system is turned on, an overhead graphic of a vehicle
with lane markings will be displayed in the left-hand instrument
cluster display. If the aid mode is selected when the system is
turned on, a separate white icon will also appear in the instrument cluster.
When the system is turned off, the lane marking graphics will not be
displayed.
Note:The overhead vehicle graphic may still be displayed if adaptive
cruise control is enabled.
While the system is on, the color of the lane markings will change to
indicate the system status.
