WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions and you
could lose control. An accident could be the result.
Do not use Electronic Speed Control in heavy traffic
or on roads that are winding, icy, snow-covered or
slippery.
ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by cruise control while traveling
on highways and major roadways. However, it is not a
safety system and not designed to prevent collisions.ACC will allow you to keep cruise control engaged in
light to moderate traffic conditions without the constant
need to reset your cruise control. ACC utilizes an infrared
sensor designed to detect a vehicle directly ahead of you.
NOTE:
•If the sensor does not detect a vehicle ahead of you,
ACC will maintain a fixed set speed.
•If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration automatically to
maintain a preset following distance, while matching
the speed of the vehicle ahead.

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 an accident or serious personal injury.The
ACC system:
•Does not react to pedestrians, oncoming vehicles,
and stationary objects (i.e., a stopped vehicle in a
traffic jam or a disabled vehicle).
(Continued)
WARNING! (Continued)
•Cannot take street, traffic, and weather conditions
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.
•May not detect a vehicle ahead when strong light
(for example, sunrise or sunset) is directly shining
on the front of the vehicle.
•Can only apply a maximum of 25% of the vehicle’s
braking capability, and will not bring the vehicle
to a complete stop.

WARNING!
You should switch off the ACC system:
•When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situations
(i.e., in highway construction zones).
•When entering a turn lane or highway off ramp;
when driving on roads that are winding, icy,
snow-covered, slippery, or have steep uphill or
downhill slopes; and when towing a trailer.
•When circumstances do not allow safe driving at a
constant speed.
Failure to follow these warnings can result in an
accident or serious personal injury.The Cruise Control system has two control modes.
•Adaptive cruise control mode for maintaining an
appropriate distance between vehicles.
•Normal (fixed speed) cruise control mode for cruising
at a constant preset speed. For additional information,
refer to “Normal (Fixed Speed) Cruise Control Mode”
in this section. Note: The system will not react to
preceding vehicles. Always be aware of the mode
selected.
You can change the mode by using the control lever. The
two control modes function differently. Always confirm
which mode is selected.
Adaptive Cruise Control (ACC) Operation
The speed control lever (located on the right side of the
steering wheel) operates the ACC system.
156 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

To Activate
Push and release the ON/OFF/MODE button located on
the end of the speed control lever. The ACC menu in the
EVIC displays “ACC READY.”
To turn the system OFF, push and release the ON/OFF/
MODE button again. At this time, the system will turn off
and the EVIC will display “CRUISE OFF.”WARNING!
Leaving the Adaptive Cruise Control (ACC) system
on when not in use is dangerous. You could acciden-
tally set the system or cause it to go faster than you
want. You could lose control and have an accident.
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
lever downward (SET/DECEL) and release. The EVIC
will display the set speed.
158 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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. This
could cause an accident and/or serious injury.
To Vary the Speed Setting
While ACC is set, you can increase the set speed by lifting
and holding the lever up (RESUME/ACCEL). If the lever
is continually held, the set speed will continue to increase
in 5 mph (10 km/h) increments until the lever is released.
The increase in set speed is reflected in the EVIC display.
Tapping the lever up once will result in a 1 mph (1 km/h)
increase in set speed. Each subsequent tap of the lever
results in an increase of 1 mph (1 km/h).While ACC is set, the set speed can be decreased by
pushing and holding the lever down (SET/DECEL). If
the lever is continually held, the set speed will continue
to decrease in 5 mph (10 km/h) increments until the lever
is released. The decrease in set speed is reflected in the
EVIC display.
Tapping the lever down once will result ina1mph
(1 km/h) decrease in set speed. Each subsequent tap of
the lever results in a decrease of 1 mph (1 km/h).
NOTE:
•When you use the lever to decelerate, if the engine’s
braking power does not slow the vehicle sufficiently to
reach the set speed, the brake system will automati-
cally slow the 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
“ATTENTION” will flash in the EVIC and a chime will
sound while ACC continues to apply its maximum
braking capacity. When this occurs, you should immedi-
ately apply the brakes as needed to maintain a safe
distance from the vehicle ahead.

activity occurs, which may include any of the following:
•Set speed change
•Distance setting change
•System cancel
•Acquisition/loss of Target
•Driver override
•System off
•Proximity warning
•ACC warning
The EVIC will return to the last display selected
after five seconds of no ACC activity.

Display Warnings and Maintenance
ACC Blinded Warning
The ACC Blinded Warning will display when conditions
temporarily limit system performance. This most often
occurs at times of poor visibility, such as in snow, fog,
heavy rain, or when driving into direct sunlight (sunrise
or sunset). The ACC system may also become tempo-
rarily blinded due to obstructions, such as dirt or ice. In
these cases, the EVIC will display “ACC Blinded” and
the system will deactivate.
NOTE:If the ACC Blinded Warning is active Normal
(Fixed Speed) Cruise Control is still available. For addi-
tional information refer to “Normal (Fixed Speed) Cruise
Control Mode” in this section.
168 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE:Installing a vehicle front-end protector or an
aftermarket grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit ACC
operation.
ACC Unavailable Warning
If the system turns off, and the EVIC displaysACC
UNAVAILABLE,there may be a temporary malfunction
that limits ACC functionality. Although the vehicle is still
drivable under normal conditions, ACC will be tempo-
rarily 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 “SERVICE
ACC,” 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.

Normal (Fixed Speed) Cruise Control Mode
In addition to adaptive cruise control mode, a normal
(fixed speed) cruise control mode is available for cruising
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 25 mph
(40 km/h).
To change modes, press and hold theON/OFF/MODE
button for at least one second in either the OFF state or
the READY state.Normal Cruise Readywill be dis-
played once the mode becomes available. To switch back
to ACC, press and hold the “ON/OFF/MODE” button
again for at least one second.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
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, tap the lever
down and release (“SET/DECEL”). The EVIC will dis-
play the set speed.
NOTE:You must observe the display when setting or
changing speed, not the speedometer.
