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.

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.
Driver Controls

•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.
If the front end of the vehicle is hit or damaged, the radar sensing zone
may be altered causing missed or false vehicle detections. Check with
your authorized dealer to have the ACC radar checked for proper
coverage and operation.
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.

Using hill start assist
Hill start assist is activated automatically when the vehicle is stopped on
a slope greater than five degrees. Hill start assist operates with the
vehicle facing downhill if reverse gear is selected.
WARNING:You must remain in the vehicle once you have
activated hill start assist.
Activating hill start assist
1. Press the brake pedal to bring the vehicle to a complete standstill.
Keep the brake pedal pressed.
2. If the sensors detect that the vehicle is on a slope, hill start assist will
be activated automatically.
3. When you remove your foot from the brake pedal, the vehicle will
remain on the slope without rolling away for approximately up to three
seconds. This hold time will automatically be extended if you are in the
process of driving off.
4. Drive off in the normal manner. The brakes will be released
automatically.
WARNING:If the engine is revved excessively, or if a
malfunction is detected when hill start assist is active, hill start
assist will be deactivated.
If your vehicle gets stuck in mud or snow
Note:Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Note:Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
It may be beneficial to turn the AdvanceTracwith RSC system off so
the wheels are allowed to spin.

Operation
The radar sensor detects vehicles
ahead that are moving in the same
direction as your vehicle.
If the radar detects that your
vehicle is rapidly closing in on
another vehicle, a red warning light
will illuminate and an audible
warning chime will sound.
After that, if the risk of collision
further increases after the warning
light, the brake support prepares
the brake system for rapid braking.
This may be apparent to the driver.
However, the system will not
automatically activate the brakes.
The vehicle will not stop unless the driver presses the brake pedal. If the
brake pedal is pressed then braking is implemented with full brake
function, even if the force on the brake pedal is light.
The collision warning system is active at speeds above approximately
5 mph (8 km/h).
Collision warning system limitations
Due to the nature of radar technology, there may be certain instances
where vehicles will not provide a collision warning. These include:
•Stationary or slow moving vehicles below 6 mph (10 km/h).
•Pedestrians or objects in the roadway.
•Oncoming vehicles in the same lane.
•Severe weather conditions (see also blocked sensor section).
•Debris build-up on the grille near the headlamps (see block sensor
section).
•Small distance to vehicle ahead.
•Steering wheel and pedal movements are large (very active driving
style).
•High interior temperatures, which may deactivate the illumination or
the warning lamps until the interior temperature reduces (audible
warning will alert the driver).
In addition, sun load and sunglasses may reduce the visibility of the
warning lamps. Therefore, it is recommended to keep the audible
warning on.

If the front end of the vehicle is hit or damaged, the radar sensing zone
may be altered causing missed or false collision warnings. Check with
your authorized dealer to have your collision warning radar checked for
proper coverage and operation.
WARNING:The collision warning system’s brake support can
only help reduce the speed at which a collision occurs if the
driver applies the vehicle’s brakes. The brake pedal must be pressed
just like any typical braking situation.
Blocked sensor
If a message regarding a blocked
sensor is displayed, the radar signals
from the sensor, located behind a
fascia cover near the driver side of
the lower grille, have been
obstructed. When the radar signals
are obstructed, a vehicle ahead
cannot be detected and the collision
warning system will not function.
The following table lists possible
causes and actions for this message being displayed.
Cause Action
The surface of the radar in the
grille is dirty or obstructed in
some wayClean the grille surface in front of
the radar or remove the object
causing the obstruction
The surface of the radar in the
grille is clean but the message
remains in the displayWait a short time. It may take
several minutes for the radar to
detect that it is no longer
obstructed
Heavy rain, spray, snow, or fog is
interfering with the radar signalsThe collision warning system is
temporarily disabled. Collision
warning should automatically
reactivate a short time after the
weather conditions improve.
