NOTE:Any chassis/suspension modifications to the ve-
hicle will effect the performance of the Adaptive Cruise
Control.
Activating Adaptive Cruise Control (ACC)
You can only activate ACC if the vehicle speed is above
18 mph (30 km/h).
When the system is turned on and in the READY state,
the Electronic Vehicle Information Center (EVIC) dis-
plays “Adaptive Cruise Ready.”
When the system is OFF, the EVIC displays “Adaptive
Cruise Control Off.” NOTE:
You cannot enable ACC under the following
conditions:
• When in Four-Wheel Drive Low.
• When you apply the brakes.
• When the parking brake is set.
• When the automatic transmission is in PARK, RE-
VERSE or NEUTRAL.
• When pushing the RES +button without a previously
set speed in memory.3

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 accidentally
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. 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 EVIC.

•The system will not be controlling the distance be-
tween your vehicle and the vehicle ahead. The vehicle
speed will only be determined by the position of the
accelerator pedal.To Cancel
The system will disable ACC without erasing the
memory if:
• You softly tap the brake pedal.
• You depress the brake pedal.
• You press the CANCEL switch.
• The speed of the vehicle goes below 15 mph
(25 km/h).
• An Anti-Lock Brake System (ABS) event occurs.
• A Trailer Sway Control (TSC) event occurs.
• The transmission is shifted into NEUTRAL.
• The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.

NOTE:If ACC is resumed or set with the ESC/TCS off,
ESC will automatically be re-engaged.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. Pressing the RES
+button once will result ina1mph
(1.6 km/h) increase in set speed. Each subsequent tap of
the button results in an increase of 1 mph (1.6 km/h).
While ACC is set, the set speed can be decreased by
pressing and holding the SET -button. If the button is
continually pressed, the set speed will continue to de-
crease in 5 mph (8 km/h) increments until the button is
released. The decrease in set speed is reflected in the
EVIC display.
Pressing the SET -button once will result ina1mph
(1.6 km/h) decrease in set speed. Each subsequent tap of
the button results in a decrease of 1 mph (1.6 km/h).

NOTE:
•When you use the SET -button to decelerate, if the
engine’s braking power does not slow the vehicle
sufficiently to reach the set speed, the brake system
will automatically slow the vehicle.
• The ACC system can only apply a maximum of 25% of
the vehicle’s braking capability and will not bring the
vehicle to a complete stop.
• 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 down-
hill. This is normal operation and necessary to main-
tain 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 (me-
dium), 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 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 the
same 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 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.
Menu ButtonPress 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.”
