SELECTING THE INTELLIGENT
CRUISE CONTROL MODE
When you push the ON/OFF switch1, you can
choose the cruise control mode between the
vehicle-to-vehicle distance control mode and the
conventional (fixed speed) cruise control mode.
To choose the vehicle-to-vehicle distance control
mode, push the ON/OFF switch quickly. The
CRUISE indicator light will appear in the vehicle
information display.
Once a control mode is chosen and activates, it
cannot be changed to the other cruise control mode. To change the mode, push the ON/OFF
switch once, then turn on the system again.
Always confirm the setting in the vehicle informa-
tion display.
WARNING
●
In the conventional (fixed speed) cruise
control mode, a warning chime will not
sound to warn you if you are too close
to the vehicle ahead.
● Pay special attention to the distance
between your vehicle and the vehicle
ahead of you or a collision could occur.
For the vehicle-to-vehicle distance control mode,
see the following description. For the conven-
tional (fixed speed) cruise control mode, see
“Conventional (fixed speed) cruise control mode”
later in this section.
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE
In the vehicle-to-vehicle distance control mode,
the Intelligent Cruise Control (ICC) system auto-
matically maintains a selected distance from the
vehicle in front of you according to that vehicle’s
speed, up to the set speed or at the set speed
when the road ahead is clear. With ICC, the driver can maintain the same
speed as other vehicles without the constant
need to adjust the speed as you would with a
normal cruise control system.

sensor cannot detect the reflector of the vehicle
ahead, the ICC system may not maintain the
selected distance.
The following are some conditions in which the
sensor cannot detect the signals:● When the reflector is positioned high on the
vehicle (trailer, etc.) .
● When the reflector on the vehicle ahead is
missing, damaged or covered.
● When the reflector is covered with dirt, snow
and road spray.
● When the snow or road spray from other
vehicles reduces the sensor’s visibility.
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
visibility.
● When excessively heavy baggage is loaded
in the rear seat or the cargo area of your
vehicle.
● When your vehicle is towing a trailer, etc.
The ICC system is designed to automatically
check the sensor’s operation. When the sensor is
covered with dirt or obstructions, the system will
automatically be canceled while allowing con-
ventional cruise control to remain operational. If
the sensor is covered with ice, a transparent or translucent vinyl bag, etc., the ICC system may
not detect them. In these instances, the vehicle-
to-vehicle distance control mode may not cancel
and may not be able to maintain the selected
following distance from the vehicle ahead. Be
sure to clean the sensor regularly.
The vehicle-to-vehicle distance control mode is
designed to maintain a selected distance and
reduce the speed to match the speed of a slower
vehicle ahead; the system decelerates the ve-
hicle as necessary. However, the ICC system can
only apply up to 25% of the vehicle’s total braking
power. This system should only be used when
traffic conditions allow vehicle speeds to remain
fairly constant or vehicle speeds change gradu-
ally. If a vehicle moves into the traveling lane
ahead or if a vehicle traveling ahead rapidly de-
celerates, the distance between vehicles may
become closer because the ICC system cannot
decelerate the vehicle quickly enough. If this oc-
curs, the ICC system will sound a warning chime
and blink the system display to notify the driver to
take necessary action.
The system will cancel and a warning chime will
sound if the speed falls below approximately 20
MPH (32km/h) . The system will also disengage
below the 20 MPH (32km/h) cut-off speed or
over the maximum set speed.
Refer to “Approach warning” later in this section.The following items are controlled when the se-
lector lever is in any D (Drive) position.
● When there are no vehicles traveling ahead,
the vehicle-to-vehicle distance control
mode maintains the speed set by the driver.
The set speed range is between approxi-
mately 25 and 89 MPH (40 and 144 km/h) .
● When there is a vehicle traveling ahead, the
vehicle-to-vehicle distance control mode
adjusts the speed to maintain the distance
selected by the driver from the vehicle
ahead. The adjusting speed range is be-
tween approximately 20 MPH (32 km/h) and
the set speed.
● When the vehicle traveling ahead has moved
out from its lane of travel, the vehicle-to-
vehicle distance control mode accelerates
and maintains speed up to the set speed.
The ICC 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 approaching toll gates
or traffic congestion.

System operation
WARNING
Normally when controlling the distance to
a vehicle ahead, this system automatically
accelerates or decelerates your vehicle
according to the speed of the vehicle
ahead. Depress the accelerator to prop-
erly accelerate your vehicle when accel-
eration is required for a lane change. De-
press the brake pedal when deceleration
is required to maintain a safe distance to
the vehicle ahead due to its sudden brak-
ing or if a vehicle cuts in. Always stay alert
when using the 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. The
CRUISE indicator light in the vehicle information
display comes on.
Vehicle detected ahead:
When a vehicle is detected in the lane ahead, the
ICC system decelerates the vehicle by control-
ling 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 a driver
selected distance.
The stoplights of the vehicle come on and
the brake pedal depresses when braking is
performed by the ICC system.
CAUTION
Never place your foot under the brake
pedal, when the brake is operated by the
Intelligent Cruise Control system. You
may get your foot caught in the pedal.
When a vehicle ahead is detected, the vehicle
ahead detection indicator comes on. The ICC
system will also display the set speed and se-
lected 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 the vehicle.

When passing another vehicle,the set speed
indicator will flash when the vehicle speed ex-
ceeds the set speed. The vehicle detect indicator
will turn off when the area ahead of the vehicle is
open. When the pedal is released, the vehicle will
return to the previously set speed. The CRUISE
indicator light will appear on the vehicle informa-
tion display.
Although your vehicle may be at the set vehicle
speed based on ICC system control, depress the
accelerator pedal when it is necessary to accel-
erate your vehicle rapidly.
How to change the set vehicle speed
To cancel the preset speed, use any of these
methods:
● Push the CANCEL switch. The set vehicle
speed indicator will go out.
● Tap the brake pedal. The set vehicle speed
indicator will go out.
● Turn the ON/OFF switch off. Both the
ON/OFF switch indicator and set vehicle
speed indicator will go out.
To reset at a faster cruising speed, use one
of the following methods:
● Depress the accelerator pedal. When the
vehicle attains the desired speed, push and
release the COAST/SET switch.
● Push and hold the ACCEL/RES switch. The
set vehicle speed will increase by approxi-
mately 5 MPH (5 km/h for Canada) .
● Push, then quickly release the ACCEL/RES
switch. Each time you do this, the set speed
will increase by approximately 1 MPH (1
km/h for Canada) . To reset at a slower cruising speed,
use one
of the following methods:
● Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
COAST/SET switch and release it.
● Push and hold the COAST/SET switch. The
set vehicle speed will decrease by approxi-
mately 5 MPH (5 km/h for Canada) .
● Push, then quickly release the COAST/SET
switch. Each time you do this, the set speed
will decrease by approximately 1 MPH (1
km/h for Canada) .
To resume the preset speed, push and re-
lease the ACCEL/RES switch. The vehicle will
resume the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h) .

How to change the set distance to the
vehicle ahead
The distance to the vehicle ahead can be se-
lected at any time depending on the traffic con-
ditions.
Each time the DISTANCE switch is pressed, the
set distance will change to long, medium, short
and back to long again in that sequence.●
The distance to the vehicle ahead will
change according to the vehicle speed. The
higher the vehicle speed, the longer the dis-
tance.
● If the engine is stopped, the set distance
becomes “long”. (Each time the engine is
started, the initial setting becomes “long”.)
● The CRUISE indicator light will appear in the
vehicle information display.
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 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 the accelerator pedal is depressed,
overriding the system.
● When a vehicle cuts in near your vehicle.
The warning chime will not sound when your
vehicle approaches vehicles that are parked or
moving slowly.
