NOTE:In order to ensure proper operation, the Electronic
Speed Control System has been designed to shut down if
multiple Speed Control functions are operated at the same
time. If this occurs, the Electronic Speed Control System can
be reactivated by pushing the Electronic Speed Control
ON/OFF button and resetting the desired vehicle set speed.
To Activate
Push the ON/OFF button. The Cruise Indicator Light in the
instrument cluster will illuminate. To turn the system off,
push the ON/OFF button a second time. The Cruise Indica-
tor Light will turn off. The system should be turned off when
not in use.
WARNING!
Leaving the Electronic Speed Control system on
when not in use is dangerous. You could accidentally
set the system or cause it to go faster than you want.
(Continued)
WARNING!(Continued)
You could lose control and have an accident. Always
leave the system OFF when you are not using it.
To Set A Desired Speed
Turn the Electronic Speed Control ON. When the vehicle
has reached the desired speed, press the SET (-) button and
release. Release the accelerator and the vehicle will operate
at the selected speed.
NOTE:The vehicle should be traveling at a steady speed
and on level ground before pressing the SET button.
To Deactivate
A soft tap on the brake pedal, pushing the CANCEL
button, or normal brake pressure while slowing the vehicle
will deactivate Electronic Speed Control without erasing
the set speed memory. Pressing the ON/OFF button or
turning the ignition switch OFF erases the set speed
memory.

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:
– Does not react to pedestrians, oncoming ve-
hicles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
(Continued)
WARNING!(Continued)
– 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.

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.
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.”

•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.

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 (10 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 km/h) increase in set speed. Each subsequent tap of
the button results in an increase of 1 mph (1 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 (10 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 km/h) decrease in set speed. Each subsequent tap of
the button results in a decrease of 1 mph (1 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.
226 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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.

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.
Offset Driving
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel. There will 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.
Turns And Bends
When driving on a curve with ACC engaged, the system
may decrease the vehicle speed and acceleration for
convenience reasons, with no target vehicle detected.
Once the vehicle is out of the curve the system will
resume your original Set Speed. This is a part of normal
ACC system functionality.
