WARNING!
• Adaptive Cruise Control (ACC) is a convenience system. It is not a substitute for active driving involve -
ment. It is always the driver’s responsibility to be atten -
tive of road, traffic, and weather conditions, vehicle
speed, distance to the vehicle ahead; and, most impor -
tantly, 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. Failure to follow these warn -
ings 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 limited upon adverse sight
distance conditions.
• Does not always fully recognize complex driving conditions, which can result in wrong or missing
distance warnings.
• Will bring the vehicle to a complete stop whilefollowing a target vehicle and hold the vehicle for
approximately two seconds in the stop position. At
this point, there will be an “ACC may cancel soon”
chime and warning to the driver. When ACC is
cancelled, the system will release the brakes and the
driver must take over braking. The system can be
resumed when the target vehicle drives off by
releasing the brake and pushing the resume button
on the steering wheel.
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy snow, sleet, heavy traffic, and complex driving situations (i.e., in
highway construction zones).
• When entering a turn lane or highway off ramp; when driving on roads that are winding, icy, snow-covered,
slippery, or have steep uphill or downhill slopes.
• When towing a trailer up or down steep slopes.
• When circumstances do not allow safe driving at a constant speed.

To Turn Off
The system will turn off and clear the set speed in memory if:
• The Adaptive Cruise Control (ACC) on/off button ispushed.
• The Normal (Fixed Speed) Cruise Control on/off button is pushed.
• The ignition is turned OFF.
• You switch to Four-Wheel Drive Low.
To Resume
If there is a set speed in memory push the RES (+) button and
then remove your foot from the accelerator pedal. The instru-
ment cluster display will display the last set speed.
NOTE:
• If your vehicle stays at standstill for longer than two seconds, the driver will have to push the RES (+) button to
reengage the ACC to the existing set speed.
• ACC cannot be resumed if there is a stationary vehicle in-front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Speed
While ACC is set, you can increase the set speed by pushing
the RES (+) button.
The speed increment shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the RES (+) button once will result in a 1 mph increase in set speed. Each subsequent tap of the button
results in an increase of 1 mph.
WARNING!
The Resume function should only be used if traffic and
road conditions permit. Resuming a set speed that is too
high or too low for prevailing traffic and road conditions
could cause the vehicle to accelerate or decelerate too
sharply for safe operation. Failure to follow these
warnings can result in a collision and death or serious
personal injury.

298 STARTING AND OPERATING
Brake Alert
NOTE:
The “Brake!” Screen in the instrument cluster display is a
warning for the driver to take action and does not necessarily
mean that the Forward Collision Warning system is
applying the brakes autonomously.
Trailer Detect — If Equipped
When a trailer is detected, the ACC system automatically
defaults to the longest setting (four bars). The setting can be
overridden by pushing the Distance Button on the steering
wheel.
Overtake Aid
When driving with ACC engaged and following a vehicle,
the system will provide an additional acceleration up to the
ACC set speed to assist in passing the vehicle. This addi -
tional acceleration is triggered when the driver utilizes the
left turn signal and will only be active when passing on the
left hand side.
ACC Operation At Stop
In the event that 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 standstill, 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, then ACC will
cancel and the driver must take over braking. When the
target vehicle drives off, ACC can be resumed by releasing
the brake and pushing the RES (+) button.

STARTING AND OPERATING 299
NOTE:
After the ACC system holds your vehicle at a standstill for
approximately two seconds, a chime will sound and an
“ACC may cancel soon” warning will display. The brakes
will release when ACC is cancelled and the driver must take
over braking.
While ACC is holding your vehicle at a standstill, if the
driver seatbelt is unbuckled or the driver door is opened, the
parking brake will be activated, and the ACC system will be
cancelled.
