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.
•An Anti-Lock Brake System (ABS) event occurs.
•If 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 and release the ON/OFF button.
•You turn OFF the ignition.

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.
Distance Set 3 (long)
214 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 Indicator”
icon, and the system adjusts vehicle speed automatically 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.

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.
Press and release the UP or DOWN button until “ACC”
or “Cruise” is highlighted in the EVIC. Status of the ACC
or Cruise is also displayed in the menu line.
Press and release the SELECT (right arrow) button to
display the following information:
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.”

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.
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.
222 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Turns And Bends
In turns or bends, ACC may detect a vehicle ahead too
late or too early. This may cause your vehicle to brake late
or unexpectedly. Give extra attention in curves and be
ready to apply the brakes if necessary. Be sure to select an
appropriate speed while driving in curves.ACC may occasionally provide braking and/or a driver
alert that you consider unnecessary. This may be the
system’s response to signs, guardrails, and other station-
ary objects in a curve. This may also occur at the base of
steep hills. This is normal operation and your vehicle
does not require service.

Using ACC On Hills
When driving on hills, ACC may not detect a vehicle in
your lane. Depending on the speed, vehicle load, traffic
conditions, and the steepness of the hills, ACC perfor-
mance may be limited.
Lane Changing
ACC will not detect a vehicle until it is completely in the
lane in which you are traveling. In the illustration shown,
ACC has not yet detected the vehicle changing lanes and
it may not detect the vehicle until it’s too late for the ACC
system to take action. ACC will not detect a vehicle until
it is completely in the lane. There will not be sufficient
distance to the lane-changing vehicle. Always be atten-
tive and ready to apply the brakes if necessary.
224 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Stationary Objects And Vehicles
ACC does not react to stationary objects and stationary
vehicles. For example, ACC will not react in situations
where the vehicle you are following exits your lane and
the vehicle ahead is stopped in your lane. Always be
attentive and ready to apply the brakes if necessary.

Normal (Fixed Speed) Cruise Control Mode
In addition to Adaptive Cruise Control mode, a normal
(fixed speed) Cruise Control mode is available for cruis-
ing at fixed speeds. The normal Cruise Control mode is
designed to maintain a set cruising speed without requir-
ing the driver to operate the accelerator. Cruise Control
can only be operated if the vehicle speed is above 20 mph
(32 km/h).
