• The vehicle must be completely stopped.
• The gear selector must be in a forward gear and the

brake pedal depressed.

The engine will shut down, the tachometer will move to
the zero position and the Stop/Start telltale will illuminate
indicating you are in Autostop. Customer settings will be
maintained upon return to an engine running condition.

Possible Reasons The Engine Does Not Autostop

Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
Detailed information about the operation of the Stop/Start
system may be viewed in the instrument cluster display
Stop/Start Screen. In the following situations the engine
will not stop:
• Driver’s seat belt is not buckled.
• Driver’s door is not closed.
• Battery temperature is too warm or cold.
• Battery charge is low.
• The vehicle is on a steep grade.
• Cabin heating or cooling is in process and an acceptable

cabin temperature has not been achieved.

• HVAC is set to full defrost mode at a high blower speed.
• HVAC set to MAX A/C.
• Engine has not reached normal operating temperature.
• The transmission is not in a forward gear.
• Hood is open.
• Vehicle is in 4WD LOW transfer case mode.
• Brake pedal is not pressed with sufficient pressure.
Other Factors Which Can Inhibit Autostop Include:
• Accelerator pedal input.
• Engine temp too high.
• 5 MPH (8 km/h) threshold not achieved from previous

AUTOSTOP.

• Steering angle beyond threshold.
• Adaptive Cruise Control is on and speed is set.
It may be possible for the vehicle to be driven several times
without the STOP/START system going into a STOP/
START READY state under more extreme conditions of the
items listed above.

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 acceleration (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead.

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.

266

STARTING AND OPERATING

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
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.

(Continued)

WARNING! (Continued)

• In vehicles with automatic transmission, will bring

the vehicle to a complete stop while following a
target vehicle and hold the vehicle for approxi-
mately three minutes in the stop position. If the
target vehicle does not start moving within three
minutes, the parking brake will be activated and
the ACC system will be canceled.

You should turn the ACC system off:
• 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 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 show 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.
• 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.
• The driver switches ESC to full-off mode.
• Manual transmission is not in a forward gear, if

equipped.

• Manual transmission is in NEUTRAL or clutch pressed

down for a fixed amount of time, if equipped.

• Manual transmission vehicle speed drops below 15 mph

(24 km/h), if equipped.

270

STARTING AND OPERATING

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.
• You switch to Four-Wheel Drive Low.

To Resume

If there is a set speed in the memory, push the RES button
and then remove your foot from the accelerator pedal. The
instrument cluster display will show the last set speed.

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 if equipped. Refer to “Getting To
Know Your Instrument Panel” for more information. 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 SET (+) 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.

• If the button is continually pushed, the set speed will

continue to increase in 5 mph increments until the
button is released. The increase in set speed is reflected
in the instrument cluster display.

Metric Speed (km/h)
• Pushing the SET (+) button once will result in a 1 km/h

increase in set speed. Each subsequent tap of the button
results in an increase of 1 km/h.

STARTING AND OPERATING

271

• If the button is continually pushed, the set speed will

continue to increase in 10 km/h increments until the
button is released. The increase in set speed is reflected
in the instrument cluster display.

To Decrease Speed

While ACC is set, the set speed can be decreased by
pushing the SET (-) button.

The driver’s preferred units can be selected through the
instrument panel settings if equipped. Refer to “Getting To
Know Your Instrument Panel” for more information. The
speed decrement shown is dependant on the chosen speed
unit of U.S. (mph) or Metric (km/h):

U.S. Speed (mph)
• Pushing the SET (-) button once will result in a 1 mph

decrease in set speed. Each subsequent tap of the button
results in a decrease of 1 mph.

• If the button is continually pushed, the set speed will

continue to decrease in 5 mph decrements until the
button is released. The decrease in set speed is reflected
in the instrument cluster display.

Metric Speed (km/h)
• Pushing the SET (-) button once will result in a 1 km/h

decrease in set speed. Each subsequent tap of the button
results in a decrease of 1 km/h.

• If the button is continually pushed, the set speed will

continue to decrease in 10 km/h decrements until the
button is released. The decrease in set speed is reflected
in the instrument cluster display.

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.

• If equipped with a manual transmission, the ACC sys-

tem applies the brake down to 15 mph (24 km/h) when
following a target vehicle.

272

STARTING AND OPERATING

• If equipped with a automatic transmission, 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 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 will show in the instrument cluster display.

Distance Setting 4 Bars (Longest)

6

STARTING AND OPERATING

273

Distance Setting 3 Bars (Long)

Distance Setting 2 Bars (Medium)

274

STARTING AND OPERATING

To increase the distance setting, push the Distance Setting
— Increase button and release. Each time the button is
pushed, the distance setting increases by one bar (longer).
Once the longest setting is reached, if the button is pushed
again it will be set to the shortest setting available.

If there is no vehicle ahead, the vehicle will maintain the set
speed. If a slower moving vehicle is detected in the same
lane, the instrument cluster display will show the “Sensed
Vehicle Indicator” icon, and the system adjusts vehicle
speed automatically to maintain the distance setting, re-
gardless 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.

Distance Setting 1 Bar (Short)
