To change the distance setting, press the Distance button
and release. Each time the button is pressed, the distance
setting adjusts between long, medium, and short.
If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in thesame lane, the EVIC displays the “Sensed Vehicle Indi-
cator” icon, and the system adjusts vehicle speed auto-
matically 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 vehicle ahead slows to a speed below 15 mph
(24 km/h) and the system automatically disengages
itself.
•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 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 willprovide an additional acceleration based on your current
speed. The acceleration is triggered by indicating a left
turn signal.
Adaptive Cruise Control (ACC) Menu

cluster between the speedometer and the tachometer. The
information it displays depends on ACC system status.
Press the MENU button (located on the steer-
ing wheel) repeatedly until one of the follow-
ing displays in the EVIC:
Adaptive Cruise Control Off
When ACC is deactivated, the display will read
“Adaptive Cruise Control Off.”
Adaptive Cruise Control Ready
When ACC is activated but the vehicle speed setting
has not been selected, the display will read “Adaptive
Cruise Control Ready.”ACC SET
When ACC is set, the set speed will display.
The set speed will continue to display in place of the
odometer reading when changing the EVIC display
while ACC is set.

The ACC screen will display once again if any ACC
activity occurs, which may include any of the following:
•Set Speed Change
•Distance Setting Change
•System Cancel
•Driver Override
•System Off
•ACC Proximity Warning
•ACC Unavailable Warning
The EVIC will return to the last display selected
after five seconds of no ACC display activity.
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:Do not change the adjustment fasteners or pull
the sensor off of the bracket. Doing so may misalign the
sensor.
Store the sensor and bracket assembly in a safe location.
The wiring and connector must be stowed properly after
the sensor and bracket assembly is removed.
A connector plug is stowed on top of the bumper beam.
Insert the wiring connector into the connector plug.
NOTE:When the sensor is removed, Adaptive Cruise
Control, Normal Cruise Control, and Forward Collision
Warning will not be available. The cluster will display the
warning “ACC/FCW Unavailable - Service Radar Sen-
sor.”To reinstall the sensor and bracket assembly reverse the
process above. The fastener torque required to assembly
the bracket back to the beam is 6.6 ft lbs (9 Nm).
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.3

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.
Adding A Trailer Hitch
The weight of a trailer/hitch may affect the performance
of ACC. If there is a noticeable change in performance
following the installation of a trailer/hitch, or if the ACC
performance does not return to normal after removing
the trailer/hitch see your authorized dealer.
ACC/FCW Unavailable Warning
218 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

WARNING!
In the normal Cruise Control mode, the system will
not react to vehicles ahead. In addition, the proximity
warning does not activate and no alarm will sound
even if you are too close to the vehicle ahead since
the presence of the vehicle ahead nor the vehicle-to-
vehicle distance is detected. Be sure to maintain a
safe distance between your vehicle and the vehicle
ahead. Always be aware which mode is selected.
To Set A Desired Speed
When the vehicle reaches the speed desired, press the
SET-button and release. The EVIC will display the set
speed.
NOTE:You must observe the display when setting or
changing speed, not the speedometer.
To Vary The Speed Setting
There are two ways to change the set speed:
•Use the accelerator pedal to adjust the vehicle to the
desired speed and press the SET-button.
•Tap the RES+or SET-button to increase or decrease
the set speed in 1 mph (1.6 km/h) increments respec-
tively. Hold the RES+or SET-button for 5 mph
(8 km/h) increments.
To Cancel
The system will disable normal Cruise Control without
erasing the memory if:
•You softly tap or depress the brake pedal.
•You press the CANCEL button.
•The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.

To Resume
Press the RES+button and then remove your foot from
the accelerator pedal. The EVIC will display the last 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 engage Four-Wheel Drive Low.
If the Cruise Control system is turned off and reactivated,
the system will return to the last driver setting (ACC or
Normal Cruise Control).
Forward Collision Warning — If Equipped
Forward Collision Warning (FCW) warns the driver of a
potential collision with the vehicle in front of you and
prompts the driver to take action in order to avoid the
collision.
FCW monitors the information from the forward looking
sensor as well as the Electronic Brake Controller (EBC),
wheel speed sensors, i.e., to calculate a probable rear-end
collision. When the system determines that a rear-end
collision is probable a warning message (both audible
and visual) will be displayed on the EVIC. When the
system determines a collision with the vehicle in front of
you is no longer probable, the warning message will be
deactivated.
