ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by cruise control while traveling
on highways and major roadways. However, it is not a
safety system and not designed to prevent collisions.
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 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.WARNING!
•
Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driving
involvement. It is always the driver ’s responsibil-
ity to be attentive of road, traffic, and weather
conditions, 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 re-
quired 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:

WARNING!(Continued)
– Does not react to pedestrians, oncoming ve-
hicles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
– Cannot take street, traffic, and weather condi- tions into account, and may be limited upon
adverse sight distance conditions.
– Does not predict the lane curvature or the move- ment of preceding vehicles and will not compen-
sate for such changes.
– Does not always fully recognize complex driving conditions, which can result in wrong or missing
distance warnings.
– Can only apply a maximum of 25% of the vehi- cle’s braking capability, and will not bring the
vehicle to a complete stop.
WARNING!
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.
Failure to follow these warnings can result in a
collision and death or serious personal injury.
The Cruise Control system has two control modes:
• Adaptive Cruise Control mode for maintaining an
appropriate distance between vehicles.

To Activate
Push and release the ON/OFF button. The ACC menu in
the EVIC displays “Adaptive Cruise Control Ready.”To turn the system OFF, push and release the ON/OFF
button again. At this time, the system will turn off and
the EVIC will display “Adaptive Cruise Control Off.”
WARNING!
Leaving the Adaptive Cruise Control (ACC) system
on when not in use is dangerous. You could acciden-
tally 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 and release. The EVIC will display the set
speed.

To Turn Off
The system will turn off and erase the set speed in
memory if:
•You push the ON/OFF button.
• You turn OFF the ignition.
• You switch to Four-Wheel Drive Low.
To Resume Speed
Press the RES +button and release. Then remove your
foot from the accelerator pedal. The EVIC will display the
last set speed.
NOTE: You can resume ACC from a minimum of
20 mph (30 km/h).
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
While ACC is set, you can increase the set speed by
pressing and holding the RES +button. If the button is
continually pressed, the set speed will continue to in-
crease in 5 mph (8 km/h) increments until the button is
released. The increase in set speed is reflected in the EVIC
display.

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 EVIC and a chime will sound
while ACC continues to apply its maximum braking
capacity. When this occurs, you should immediately
apply the brakes as needed to maintain a safe distance
from the vehicle ahead.
The ACC Systems provides Overtake Aid when passing
on the left hand side only. When driving with ACC
engaged and following a Target vehicle, the system will
provide an additional acceleration based on your current
speed. The acceleration is triggered by indicating a left
turn signal.
Adaptive Cruise Control (ACC) Menu
The EVIC displays the current ACC system settings. The
EVIC is located in the upper part of the instrument
cluster between the speedometer and the tachometer. The
information it displays depends on ACC system status.

Display Warnings And Maintenance
“Clean Radar Sensor In Front Of Vehicle” Warning
The ACC “Clean Radar Sensor In Front Of Vehicle”
warning will display 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
EVIC will display “Clean Radar Sensor In Front Of
Vehicle” and the system will deactivate. The “Clean Radar Sensor In Front Of Vehicle” 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 “Clean Radar Sensor In Front Of
Vehicle” 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 impor-
tant 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 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
malfunction.
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 “Clean Radar Sensor In Front Of Vehicle”
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 after-
market grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit
ACC operation.
ACC Unavailable Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable, Vehicle System Error”, there may be a
temporary malfunction that limits ACC functionality.
Although the vehicle is still drivable under normal
conditions, ACC will be temporarily unavailable. If this
occurs, try activating ACC again later, following a key
cycle. If the problem persists, see your authorized dealer.
Service ACC Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable Service Radar Sensor”, it indicates
there is an internal system fault. Although the vehicle is
still drivable under normal conditions, have the system
checked by an authorized dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpect-
edly. The driver needs to stay alert and may need to
intervene.
