fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the trans-
mission gear selector.
• Do not leave the key fob in or near the vehicle (or in
a location accessible to children), and do not leave
the ignition in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
• Before moving the transmission gear selector out of
PARK, you must start the engine, and also press the
brake pedal. Otherwise, damage to the gear selector
could result.
• DO NOT race the engine when shifting from PARK
or NEUTRAL into another gear range, as this can
damage the drivetrain.
The following indicators should be used to ensure that you
have properly engaged the transmission into the PARK
position: •
Look at the transmission gear position display and
verify that it indicates the PARK position (P), and is not
blinking.
• With the brake pedal released, verify that the gear
selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake
and shift the transmission into PARK if you must exit the
vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
230 STARTING AND OPERATING

WARNING!
Speed Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control and have an accident. Do not use Speed Control
in heavy traffic or on roads that are winding, icy,
snow-covered or slippery.
To Resume Speed
To resume a previously set speed, push the RES button and
release. Resume can be used at any speed above 20 mph
(32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC button,
or normal brake pressure while slowing the vehicle will
deactivate the Speed Control without erasing the set speed
from memory.
Pushing the on/off button or turning the ignition switch
OFF erases the set speed from memory.
ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving con-
venience provided by cruise control while traveling on
highways and major roadways. However, it is not a safety
system and not designed to prevent collisions.Speed
Control function performs differently. Please refer to the
proper section within this chapter.
ACC will allow you to keep cruise control engaged in light
to moderate traffic conditions without the constant need to
reset your cruise control. ACC utilizes a radar sensor and a
forward facing camera designed to detect a vehicle directly
ahead of you.
NOTE:
• If the sensor does not detect a vehicle ahead of you, ACC
will maintain a fixed set speed.
• If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or accelerate (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead.
6
STARTING AND OPERATING 239

The Cruise Control system has two control modes:
•Adaptive Cruise Control mode for maintaining an ap-
propriate distance between vehicles.
• Normal (Fixed Speed) Cruise Control mode for cruising
at a constant preset speed. For additional information,
refer to “Normal (Fixed Speed) Cruise Control Mode” in
this section.
NOTE: Normal (Fixed Speed) Cruise Control will not react
to preceding vehicles. Always be aware of the mode
selected.
You can change the mode by using the Cruise Control
buttons. The two control modes function differently. Al-
ways confirm which mode is selected.
WARNING!
• Adaptive Cruise Control (ACC) is a convenience
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 condi-
tions, vehicle speed, distance to the vehicle ahead;
and, most importantly, brake operation to ensure safe

WARNING! (Continued)
operation of the vehicle under all road conditions.
Your complete attention is always required while
driving to maintain safe control of your vehicle.
Failure 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 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 while
following a target vehicle and hold the vehicle for
2 seconds in the stop position. If the target vehicle
does not start moving within two seconds the ACC
system will display a message that the system will

release the brakes and that the brakes must be
applied manually. An audible chime will sound
when the brakes are released.
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.
Adaptive Cruise Control (ACC) Operation
The Speed Control buttons (located on the right side of the
steering wheel) operates the ACC system. NOTE:Any chassis/suspension or tire size modifications
to the vehicle will effect the performance of the Adaptive
Cruise Control and Forward Collision Warning System.

“Adaptive Cruise Control (ACC) Off.”
NOTE:You cannot engage ACC under the following con-
ditions:
• When in Four-Wheel Drive Low.
• When you apply the brakes.
• When the parking brake is applied.
• When the automatic transmission is in PARK, REVERSE
or NEUTRAL.
• When the vehicle speed is outside of the speed range.
• When the brakes are overheated.
• When the driver ’s door is open at low speeds.
• When the driver ’s seat belt is unbuckled at low speeds.
To Activate/Deactivate

Adaptive Cruise Control Ready
242 STARTING AND OPERATING

WARNING!
Leaving the Adaptive Cruise Control (ACC) system on
when not in use is dangerous. You could accidentally
set the system or cause it to go faster than you want.
You could lose control and have a collision. Always
leave the system off when you are not using it.
To Set A Desired ACC Speed
When the vehicle reaches the speed desired, push the SET
(+)button or the SET (-)button and release. The instrument
cluster display will display the set speed. If the system is set when the vehicle speed is below 20 mph
(32 km/h), the set speed shall be defaulted to 20 mph
(32 km/h). If the system is set when the vehicle speed is
above 20 mph (32 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 proximity.
Remove your foot from the accelerator pedal. If you do not,
the vehicle may continue to accelerate beyond the set
speed. If this occurs:
• The message “DRIVER OVERRIDE” will display in the
instrument cluster display.
• The system will not be controlling the distance between
your vehicle and the vehicle ahead. The vehicle speed
will only be determined by the position of the accelera-
tor pedal.
To Cancel
The following conditions cancel the system:
• The brake pedal is applied.
• The CANC button is pushed.
• An Anti-Lock Brake System (ABS) event occurs.
Adaptive Cruise Control Off
6
STARTING AND OPERATING 243

•The gear selector is removed from the DRIVE position.
• The braking temperature exceeds normal range (over-
heated).
• The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.
• The vehicle parking brake is applied.
• Driver seatbelt is unbuckled at low speeds.
• Driver door is opened at low speeds.
NOTE: If your vehicle stays at standstill for longer than
two seconds, then the system will cancel and the brake
force will be ramped-out. The driver will have to apply the
brakes to keep the vehicle at a standstill.
To Turn Off
The system will turn off and clear the set speed in memory
if:
• The Adaptive Cruise Control (ACC) on/off button is
pushed.
• The Normal (Fixed Speed) Cruise Control on/off button
is pushed.
• The ignition is turned OFF.
To Resume
If there is a set speed in memory push the RES (resume)
button and then remove your foot from the accelerator
pedal. The instrument cluster display will display the last
set speed.
NOTE: ACC cannot be resumed if there is a stationary
vehicle in-front of your vehicle in close proximity.
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.
To Vary The Speed Setting
To Increase Speed
While ACC is set, you can increase the set speed by
pushing the SET (+)button.
The driver’s preferred units can be selected through the
instrument panel settings. Refer to “Getting To Know Your
244 STARTING AND OPERATING

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 decelerate, if the
engine’s braking power does not slow the vehicle suffi-
ciently to reach the set speed, the brake system will
automatically slow the vehicle.
• The ACC system decelerates the vehicle to a full stop
when following a target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill, after two seconds
the driver will either have to push the RES (resume)
button, or apply the accelerator pedal to reengage the
ACC to the existing Set Speed.
• The ACC will bring the vehicle to a complete stop while
following a target vehicle and hold the vehicle for two
seconds in the stop position. If the target vehicle does
not start moving within two seconds, the ACC system
will display a message that the system will release the
brakes and that the brakes must be applied manually. An
audible chime will sound when the brakes are released. •
The ACC system maintains set speed when driving up
hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting may
occur while climbing uphill or descending downhill.
This is normal operation and necessary to maintain set
speed. When driving up hill and down hill, the ACC
system will cancel if the braking temperature exceeds
normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle ahead. This
distance setting displays in the instrument cluster display.
246 STARTING AND OPERATING

Indicator” icon, and the system adjusts vehicle speed
automatically to maintain the distance setting, regardless
of the set speed.
The vehicle will then maintain the set distance until:
•The vehicle ahead accelerates to a speed above the set
speed.
• The vehicle ahead moves out of your lane or view of the
sensor.
• The distance setting is changed.
• The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE: The brake lights will illuminate whenever the ACC
system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to maintain
the set distance. If this occurs, a visual alert “BRAKE” will
flash in the instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity. 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.
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
additional acceleration is triggered when the driver utilizes
the left turn signal and will only be active when passing on
the left hand side.
Brake Alert

STARTING AND OPERATING 249

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
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, 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.
While ACC with Stop is holding your vehicle at a stand-
still, if the driver seatbelt is unbuckled 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 pedestrians, vehicles or objects
