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

continue to decrease until the button is released, then the
new set speed will be established.

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 until the button is released, then the
new set speed will be established.

To Accelerate For Passing

Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.

Using Speed Control On Hills

The transmission may downshift on hills to maintain the
vehicle set speed.

NOTE:

The Speed Control system maintains speed up and

down hills. A slight speed change on moderate hills is
normal.

On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Speed Control.

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.

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.

STARTING AND OPERATING

287

Adaptive Cruise Control (ACC) Operation

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.
• The gear selector is removed from the DRIVE position.
• 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.
• The braking temperature exceeds normal range (over-

heated).

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.

290

STARTING AND OPERATING

• 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
Instrument Panel” for more information. The speed incre-
ment 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

291

• 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. Refer to “Getting To Know Your
Instrument Panel” for more information. The speed decre-
ment 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.

• The ACC system applies the brake down to a full stop

when following a target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill, the host vehicle
will release the vehicle brakes two seconds after coming
to a full stop.

292

STARTING AND OPERATING

• 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.

Distance Setting 4 Bars (Longest)

STARTING AND OPERATING

293

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).

To decrease the distance setting, push the Distance Setting
— Decrease button and release. Each time the button is
pushed, the distance setting decreases by one bar (shorter).

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 displays the “Sensed Vehicle

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.

Distance Setting 1 Bar (Short)

STARTING AND OPERATING

295

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.

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

Adaptive Cruise Control Set

When the SET (+) or the SET (-) button (located on the
steering wheel) is pushed, the display will read “ACC
SET.”

When ACC is set, the set speed will show in the instrument
cluster display.

The ACC screen may display once again if any ACC
activity occurs, which may include any of the following:
• System Cancel
• Driver Override
• System Off
• ACC Proximity Warning
• ACC Unavailable Warning

• The instrument cluster display will return to the last

display selected after five seconds of no ACC display
activity

Display Warnings And Maintenance

“Wipe Front Radar Sensor In Front Of Vehicle”
Warning

The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and also a chime will indicate when
conditions temporarily limit system performance.

This most often occurs at times of poor visibility, such as in
snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud, dirt
or ice. In these cases, the instrument cluster display will
display “ACC/FCW Unavailable Wipe Front Radar Sen-
sor” and the system will deactivate.

The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. tunnels with reflective tiles, or
ice and snow). The ACC system will recover after the
vehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.

NOTE:

If the “ACC/FCW Unavailable Wipe Front Radar

Sensor” warning is active Normal (Fixed Speed) Cruise
Control is still available. For additional information refer to
“Normal (Fixed Speed) Cruise Control Mode” in this
section.

If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the center of the
vehicle behind the lower grille.

To keep the ACC System operating properly, it is important
to note the following maintenance items:
• Always keep the sensor clean. Carefully wipe the sensor

lens with a soft cloth. Be cautious not to damage the
sensor lens.

• Do not remove any screws from the sensor. Doing so

could cause an ACC system malfunction or failure and
require a sensor realignment.

• If the sensor or front end of the vehicle is damaged due

to a collision, see your authorized dealer for service.

• Do not attach or install any accessories near the sensor,

including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or malfunc-
tion.

298

STARTING AND OPERATING

When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.

NOTE:
• If the “ACC/FCW Unavailable Wipe Front Radar Sen-

sor” message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other
obstruction, have the radar sensor realigned at your
authorized dealer.

• Installing a snow plow, front-end protector, an aftermar-

ket grille or modifying the grille is not recommended.
Doing so may block the sensor and inhibit ACC/FCW
operation.

“Clean Front Windshield” Warning

The “ACC/FCW Limited Functionality Clean Front Wind-
shield” warning will display and also a chime will indicate
when conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as in
snow or heavy rain and fog. The ACC system may also
become temporarily blinded due to obstructions, such as
mud, dirt, or ice on windshield and fog on the inside of
glass. In these cases, the instrument cluster display will

display “ACC/FCW Limited Functionality Clean Front
Windshield” and the system will have degraded perfor-
mance.

The “ACC/FCW Limited Functionality Clean Front Wind-
shield” message can sometimes be displayed while driving
in adverse weather conditions. The ACC/FCW system will
recover after the vehicle has left these areas. Under rare
conditions, when the camera is not tracking any vehicles or
objects in its path this warning may temporarily occur.

If weather conditions are not a factor, the driver should
examine the windshield and the camera located on the
back side of the inside rear view mirror. They may require
cleaning or removal of an obstruction.

When the condition that created limited functionality is no
longer present, the system will return to full functionality.

NOTE:

If the “ACC/FCW Limited Functionality Clean

Front Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain, mud, or
other obstruction, have the windshield and forward facing
camera inspected at your authorized dealer.

Service ACC/FCW Warning

If the system turns off, and the instrument cluster displays
“ACC/FCW Unavailable Service Required” or “Cruise/

STARTING AND OPERATING

299

FCW Unavailable Service Required”, there may be an
internal system fault or a temporary malfunction that
limits ACC functionality. Although the vehicle is still
drivable under normal conditions, ACC will be temporar-
ily unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem persists,
see your authorized dealer.

Precautions While Driving With ACC

In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpectedly.
The driver needs to stay alert and may need to intervene.

Towing A Trailer

Towing a trailer is not advised when using ACC.

Offset Driving

ACC may not detect a vehicle in the same lane that is offset
from your direct line of travel, or a vehicle merging in from
a side lane. There may not be sufficient distance to the
vehicle ahead. The offset vehicle may move in and out of
the line of travel, which can cause your vehicle to brake or
accelerate unexpectedly.
