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.

•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 Setting 3

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 227

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.

Press the MENU button (located on the steering wheel)
repeatedly until one of the following 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

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.
Clean Radar Sensor Warning
232 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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 Sensor.”
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 N·m).
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.
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.3

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
neither 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.
