System operation
WARNING
Normally when controlling the distance to a
vehicle ahead, this system automatically accel-
erates or decelerates your vehicle according to
the speed of the vehicle ahead. Depress the
accelerator to properly accelerate your vehicle
when acceleration is required for a lanechange. Depress the brake pedal when decel-
eration is required to maintain a safe distance
to the vehicle ahead due to its sudden braking
or if a vehicle cuts in. Always stay alert when
using the Intelligent Cruise Control (ICC)
system.
The driver sets the desired vehicle speed based
on the road conditions. The ICC system main-
tains the set vehicle speed, similar to standard
cruise control, as long as no vehicle is detected
in the lane ahead.
The ICC system displays the set speed. Vehicle detected ahead :
When a vehicle is detected in the lane ahead,
the ICC system decelerates the vehicle by con-
trolling the throttle and applying the brakes to
match the speed of a slower vehicle ahead. The
system then controls the vehicle speed based
on the speed of the vehicle ahead to maintain
the driver selected distance.
The stoplights of the vehicle come on when brak-
ing is performed by the ICC system.
When the brake operates, a noise may be heard
or felt. This is not a malfunction.
When a vehicle ahead is detected, the vehicle
ahead detection indicator comes on. The ICC
system will also display the set speed and
selected distance.
Vehicle ahead not detected :
When a vehicle is no longer detected ahead, the
ICC system gradually accelerates your vehicle to
resume the previously set vehicle speed. The
ICC system then maintains the set speed.
When a vehicle is no longer detected the vehicle
ahead detection indicator turns off.
If a vehicle ahead appears during acceleration
to the set vehicle speed or any time the ICC
system is in operation, the system controls the
distance to that vehicle.

●The distance to the vehicle ahead will
change according to the vehicle speed. The
higher the vehicle speed, the longer the
distance. ●
If the engine is stopped, the set distance
becomes “long”. (Each time the engine is
started, the initial setting becomes “long”.)
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that vehicle
or if another vehicle cuts in, the system warns
the driver with the chime and Intelligent Cruise
Control (ICC) system display. Decelerate by
depressing the brake pedal to maintain a safe
vehicle distance if:
● The chime sounds.
● The vehicle ahead detection and set dis-
tance indicator blink.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are:
● When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing
● When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing
● When a vehicle cuts in near your vehicle
The warning chime will not sound in the follow-
ing cases:
● When your vehicle approaches vehicles that
are parked or moving slowly
● When the accelerator pedal is depressed,
overriding the system

NOTE:
The approach warning chime may sound and the
system display may blink when the ICC sensor
detects some reflectors
Awhich are fitted on
vehicles in other lanes or on the side of the road.
This may cause the ICC system to decelerate or
accelerate the vehicle. The ICC sensor may de-
tect these reflectors when the vehicle is driven
on winding roads, hilly roads or when entering
or exiting a curve. The ICC sensor may also de-
tect reflectors on narrow roads or in road con-
struction zones. In these cases you will have to
manually control the proper distance ahead of
your vehicle. Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or traffic or vehicle condi-
tion (for example, if a vehicle is being driven
with some damage).
Automatic cancellation
A chime sounds under the following conditions
and the control is automatically canceled.
●
When the vehicle speed falls below approxi-
mately 15 MPH (24 km/h)
● When the system judges the vehicle is at a
standstill
● When the selector lever is shifted to the N
(Neutral) position
● When the windshield wipers are operating at
high speed. The system may cancel when
the wipers are set to the AUTO position.
● When the VDC is turned off
● When the ABS or VDC operates
● When the parking brake is applied
● When the SNOW mode switch is pushed on.
● When the 4WD shift switch is in the 4H or 4L
position (for 4WD models) ●
When driving into a strong light (i.e., sun-
light)
● When distance measurement becomes im-
paired due to adhesion of dirt or obstruction
to the sensor
● When a wheel slips

Warning light and display
Condition A :
The chime sounds and the Intelligent Cruise
Control (ICC) system is canceled automatically
in the conditions described below. Part of the
system display will come on or blink, making it
impossible to set.
●When the VDC is turned off
● When the ABS or VDC operates
● When a tire slips ●
When driving into a strong light (i.e., sun-
light)
● When the SNOW mode switch is pushed on
● When the 4WD shift switch is in the 4H or 4L
position
Action to take :
When the conditions listed above are no longer
present, turn the system off using the ICC MAIN
switch. Turn the ICC system back on to use the
system.
Condition B :
When the sensor window is dirty, making it
impossible to detect a vehicle ahead, the ICC
system is automatically canceled.
The chime sounds and the ICC system warning
light (orange) will come on and the CLEAN
SENSOR indicator will appear.
Action to take :
If the warning light comes on, park the vehicle
in a safe place, turn the engine off. Clean the
sensor window with a soft cloth and then
perform the settings again.

●Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion.
CONVENTIONAL (FIXED SPEED) CRUISE
CONTROL MODE
This mode allows driving at a speed between 25
to 90 MPH (40 to 144 km/h) without keeping
your foot on the accelerator pedal.
WARNING
● In the conventional (fixed speed) cruise con-
trol mode, a warning chime does not sound
to warn you if you are too close to the vehicle
ahead, as neither the presence of the vehicle
ahead nor the vehicle-to-vehicle distance is
detected.
● Pay special attention to the distance be-
tween your vehicle and the vehicle ahead of
you or a collision could occur.
● Always confirm the setting in the Intelligent
Cruise Control (ICC) system display.
● Do not use the conventional (fixed speed)
cruise control mode when driving under the
following conditions.
– when it is not possible to keep the vehicle at a set speed – in heavy traffic or in traffic that varies in
speed
– on winding or hilly roads
– on slippery roads (rain, snow, ice, etc.)
– in very windy areas
Doing so could cause a loss of vehicle control
and result in an accident.
Conventional (fixed speed) cruise
control switch
1. RESUME/ACCELERATE switch:
Resumes set speed or increases speed incre-
mentally.
2. SET/COAST switch:

Operating conventional (fixed speed)
cruise control mode
To turn on the conventional (fixed speed) cruise
control mode,push and hold the MAIN switch
Afor longer than about 1.5 seconds.
When pushing the MAIN switch on, the Intelli-
gent Cruise Control (ICC) system display and the
main switch indicator are displayed on the dot
matrix liquid crystal display. After you hold the
MAIN switch on for longer than about 1.5 sec-
onds, the ICC system display turns off. The main
switch indicator stays lit. You can now set your
desired cruising speed. Pushing the MAIN
switch again will turn the system completely
off. When the Distance Control Assist (DCA) system
is on, the conventional (fixed speed) cruise
control mode cannot be turned on even though
the MAIN switch is pushed and held.
To turn on the conventional (fixed speed) cruise
control mode, turn off the DCA system. See
“DISTANCE CONTROL ASSIST (DCA) SYSTEM”
later in this section.
When the ignition switch is pushed to the OFF
position, the system is also automatically
turned off. To use the ICC system again, quickly
push and release the MAIN switch (vehicle-to-
vehicle distance control mode) or push and hold
it (conventional cruise control mode) again to
turn it on.
CAUTION
To avoid accidentally engaging cruise control,
make sure to turn the MAIN switch off when not
using the ICC system.
To set cruising speed,
accelerate your vehicle to
the desired speed, push the SET/COAST switch
and release it. (The SET indicator will come on in
the display.) Take your foot off the accelerator
pedal. Your vehicle will maintain the set speed.
● To pass another vehicle, depress the accel-
erator pedal. When you release the pedal,
the vehicle will return to the previously set
speed.
● The vehicle may not maintain the set speed
when going up or down steep hills. If this
happens, manually maintain vehicle speed.

The DCA system is designed to help assist the
driver to maintain a following distance from the
vehicle ahead. The system will decelerate as
necessary and if the vehicle ahead comes to a
stop, the vehicle decelerates to a standstill.
However, the DCA system can only apply up to
25% of the vehicles total braking power. If a
vehicle moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decelerates,
the distance between vehicles may become
closer because the DCA system cannot deceler-
ate the vehicle quickly enough. If this occurs,
the DCA system will sound a warning chime and
blink the system display to notify the driver to
take necessary action.
See “Approach warning” later in this section.
This system only brakes and moves the accel-
erator pedal upward to help assist the driver to
maintain a following distance from the vehicle
ahead. Acceleration should be operated by the
driver.The DCA system does not control vehicle speed
or warn you when you approach stationary and
slow moving vehicles. You must pay attention to
vehicle operation to maintain proper distance
from vehicles ahead.

When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the sensor may detect ve-
hicles in a different lane, or may temporarily not
detect a vehicle traveling ahead. This may
cause the system to work inappropriately.
The detection of vehicles may also be affected
by vehicle operation (steering maneuver or trav-
eling position in the lane, etc.) or vehicle con-
dition.If this occurs, the system may warn you
by blinking the system indicator and sounding
the chime unexpectedly. You will have to manu-
ally control the proper distance away from the
vehicle traveling ahead.Distance Control Assist system
display and indicators
The display is located between the speedom-
eter and tachometer.
1. Distance Control Assist (DCA) system switch indicator:
Indicates that the dynamic driver assistance
switch is ON.
2. Vehicle ahead detection indicator:
Indicates whether it detects a vehicle in
front of you.

3. Distance Control Assist system warninglight (orange):
The light comes on if there is a malfunction
in the DCA system.
Operating Distance Control Assist
(DCA) system
The DCA system turns on when the dynamic
driver assistance switch on the steering wheel
is pushed when “Distance Control Assist” is
enabled in the settings menu in the center
display. The DCA system switch indicator on the
dot matrix liquid crystal display will illuminate. The system will start to operate after the vehicle
speed becomes above approximately 3 MPH (5
km/h).
WARNING
When the DCA system is not necessary, be sure
to turn off the dynamic driver assistance
switch. Using the system when it is not neces-
sary may result in an accident.
