To decrease the distance setting, press the Distance
Setting — Decrease button and release. Each time the
button is pressed, the distance setting decreases by one
bar (shorter).
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 DID displays the “Sensed Vehicle Indica-
tor” icon, and the system adjusts vehicle speed automati-
cally 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 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 DID and a chime will sound
while ACC continues to apply its maximum braking
capacity.

NOTE:The “Brake!” Screen in the DID is a warning for
the driver to take action and does not necessarily mean
that the Forward Collision Warning system is applying
the brakes autonomously.
Overtake Aid
When driving with ACC engaged and following a target
vehicle, the system will provide an additional accelera-
tion to assist in passing vehicles in front. This additional
acceleration is triggered when the driver utilizes the left
turn signal. In locations with left hand drive traffic,
Overtake Aid is active only when passing on the left
hand side of the Target vehicles.
When a vehicle goes from a location with left hand drive
traffic to a location with right hand drive traffic, the ACC
system will automatically detect traffic direction. In this
condition, Overtake Aid is active only when passing on
the right side of the Target vehicle. This additional
acceleration is triggered when the driver utilizes the right
turn signal. In this condition the ACC system will no
longer provide Overtake Aid on the left side until it
determines that the vehicle has moved back to a location
with left hand drive traffic.

Adaptive Cruise Control (ACC) Menu
The DID displays the current ACC system settings. The
DID is located in the center of the instrument cluster. The
information it displays depends on ACC system status.
Press the ADAPTIVE CRUISE CONTROL (ACC) ON/
OFF button (located on the steering wheel) until one of
the following displays in the DID:
Adaptive Cruise Control Off
When ACC is deactivated, the display will read “Adap-
tive 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.”
Press the SET + or the SET- button (located on the
steering wheel) and the following will display in the DID:
ACC SET
When ACC is set, the set speed will display in the
instrument cluster.
The ACC screen may display once again if any ACC
activity occurs, which may include any of the following:
•Distance Setting Change
•System Cancel
•Driver Override
•System Off
•ACC Proximity Warning
•ACC Unavailable Warning
•The DID will return to the last display selected after
five seconds of no ACC display activity

Display Warnings And Maintenance
“Wipe Front Radar Sensor In Front Of Vehicle”
Warning
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and also a chime will indicate 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 DID will display “ACC/
FCW Unavailable Wipe Front Radar Sensor” and the
system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
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/FCW Unavailable Wipe Front Radar
Sensor” 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.
To keep the ACC System operating properly, it is impor-
tant 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.
3
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 173

•Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
•If the sensor or front end of the vehicle 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 “ACC/FCW Unavailable Wipe Front Radar
Sensor” 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 protector, an after-
market grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit
ACC/FCW operation.
Service ACC/FCW Warning
If the system turns off, and the DID displays “ACC/FCW
Unavailable Service Required”or “Cruise/FCW Unavail-
able Service Required”, there may be an internal system
fault or a temporary malfunction that limits ACC func-
tionality. Although the vehicle is still drivable under
normal conditions, ACC will be temporarily unavailable.
174 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

If this occurs, try activating ACC again later, following a
key cycle. If the problem persists, see your 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.
Towing A Trailer
NOTE:Towing a trailer is not advised when using ACC.
Offset Driving
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel, or a vehicle merging
in from a side lane. There may 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
stability 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.
NOTE:On tight turns ACC performance may be limited.
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 may 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 may not detect a vehicle until
it is completely in the lane. There may not be sufficient
distance to the lane-changing vehicle. Always be atten-
tive and ready to apply the brakes if necessary.

Narrow Vehicles
Some narrow vehicles traveling near the outer edges of
the lane or edging into the lane are not detected until they
have moved fully into the lane. There may not be
sufficient distance to the vehicle ahead.
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.
