Remove your foot from the accelerator pedal. If
you do not, the vehicle may continue to accel-
erate beyond the set speed. If this occurs:
•The message “DRIVER OVERRIDE” will dis-
play in the EVIC.
• The system will not be controlling the dis-
tance between your vehicle and the vehicle

NOTE:
You can resume ACC from a minimum of
18 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 SettingWhile ACC is set, you can increase the set
speed by pressing and holding the RES+
button. The increase in set speed is reflected in
the EVIC display:
While in US Mode, if the button is continually
pressed, the set speed will continue to increase
in 5 mph (8 km/h) increments. While in Metric
Mode, if the button is continually pressed, the
set speed will continue to increase in 6 mph
(10 km/h) increments. While in US Mode, pressing the RES
+button
once will result in a 1 mph (1.6 km/h) increase
in set speed. Each subsequent tap of the
button results in increase of 1 mph (1.6 km/h).
While in Metric Mode, pressing the RES +
button once will result in a 0.6 mph (1.0 km/h)
increase in set speed. Each subsequent tap of
the button results in increase of 0.6 mph
(1.0 km/h).
While ACC is set, the set speed can be de-
creased by pressing and holding the SET -
button.
If the button is held while in US Mode, the set
speed will continue to decrease in 5 mph
(8 km/h) increments.
If the button is held while in Metric Mode, the
set speed will continue to decrease in 6 mph
(10 km/h) increments.
While in US Mode, pressing the SET -button
once will result in a 1.0 mph (1.6 km/h) de-
crease in set speed. Each subsequent tap of
the button results in decrease of 1.0 mph
(1.6 km/h). While in Metric Mode, pressing the SET
-button
once will result in a 0.6 mph (1.0 km/h) de-
crease in set speed. Each subsequent tap of
the button results in decrease of 0.6 mph
(1.0 km/h).
NOTE:
• When you use the SET - button to decel-
erate, if the engine’s braking power does
not slow the vehicle sufficiently to reach
the set speed, the brake system will auto-
matically slow the vehicle.
• The ACC system can only apply a maxi-
mum of 25% of the vehicle’s braking ca-
pability and will not bring the vehicle to a
complete stop.
• The ACC system maintains set speed
when driving up hill and down hill. How-
ever, a slight speed change on moderate
hills is normal. In addition, downshifting
may occur while climbing uphill or de-
scending downhill. This is normal opera-
tion and necessary to maintain set speed.

Setting The Following Distance In
ACC
The specified following distance for ACC can
be set by varying the distance setting between
3 (long), 2 (medium), and 1 (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
EVIC.To change the distance setting, press the Dis-
tance button and release. Each time the button
is pressed, the distance setting adjusts be-
tween 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 the same lane, the EVIC
displays the “Sensed Vehicle Indicator” icon,
and the system adjusts vehicle speed auto-
matically 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 vehicle ahead slows to a speed below
15 mph (24 km/h) and the system automati-
cally disengages itself.
• The distance setting is changed.
• The system disengages. (Refer to the infor-
mation on ACC Activation).

The maximum braking applied by ACC is lim-
ited; however, 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 con-
tinues to apply its maximum braking capacity.
When this occurs, you should immediately ap-
ply the brakes as needed to maintain a safe
distance from the vehicle ahead.
Adaptive Cruise Control (ACC) MenuThe EVIC displays the current ACC system
settings. The EVIC is located in the upper part
of the instrument cluster between the speed-
ometer and the tachometer. The information it
displays depends on ACC system status.Menu Button

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 Sen-
sor 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.
Example Only
Clean Radar Sensor Warning
124

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 mal-
function or failure and require a sensor re-
alignment.
• 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 protec-
tor, an aftermarket grille or modifying the
grille is not recommended. Doing so may
block the sensor and inhibit ACC opera-
tion.
Removing ACC Sensor For Off-Roading
NOTE:
When off-roading, it may be advisable to
remove the ACC sensor. The sensor is lo-
cated behind the front lower grille in the
center of the vehicle. After removing the
lower fascia, you may remove the lower
sensor and bracket assembly.
To remove the sensor follow these instructions:
1. Unplug the connector by depressing the two
tabs on the connector and pulling it out. Do not
pull by the wiring or use any tools to remove the
connector.
2. Remove the wiring christmas tree attach-
ment from the back of the bracket. 3. Remove the two M6 fasteners that connect
the bracket to the bumper.
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 avail-
able. 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).
