disengage. Turn the MAIN switch off
once and then turn it on again.
. The cruise control will automatically
cancel if the vehicle slows more than
8 MPH (13 km/h) below the set speed.
. If you move the selector lever to the N
(Neutral) position, the cruise control
will be canceled.
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 ACCELERATE/RE-
SUME switch. When the vehicle attains
the speed you desire, release the
switch.
. Push, then quickly release the ACCEL-
ERATE/RESUME switch. Each time you
do this, the set speed will increase by
about 1 MPH (1.6 km/h).
To reset at a slower cruising speed, use
one of the following methods:
. Lightly tap the brake pedal. When the
vehicle attains the desired speed, push
the COAST/SET switch and release it. .
Push and hold the COAST/SET switch.
Release the switch when the vehicle
slows down to the desired speed.
. Push, then quickly release the COAST/
SET switch. Each time you do this, the
set speed will decrease by about 1 MPH
(1.6 km/h).
To resume the preset speed, push and
release the ACCELERATE/RESUME switch.
The vehicle will resume the last set
cruising speed when the vehicle speed is
over 25 MPH (40 km/h). The Intelligent Cruise Control (ICC) system
maintains a selected distance from the
vehicle in front of you within the speed
range of 0 to 90 MPH (0 to 144 km/h) up to
the set speed. The set speed can be
selected by the driver between 20 to 90
MPH (32 to 144 km/h).
The vehicle travels at a set speed when the
road ahead is clear.
The ICC system can be set to one of two
cruise control modes.
.
Vehicle-to-vehicle distance control
mode:
For maintaining a selected distance
between your vehicle and the vehicle
in front of you up to the preset speed.
. Conventional (fixed speed) cruise con-
trol mode:
For cruising at a preset speed.
WARNING
. Always drive carefully and attentively
when using either cruise control mode.
Read and understand the Owner’s Man-
ual thoroughly before using the cruise
control. To avoid serious injury or death,

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE
In the vehicle-to-vehicle distance control
mode, the Intelligent Cruise Control (ICC)
system automatically maintains a selected
distance from the vehicle traveling 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 con-
stant need to adjust the set speed as you
would with a normal cruise control system.

PRECAUTIONS ON VEHICLE-TO-VE-
HICLE DISTANCE CONTROL MODE
The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the distance sensor
*Adetects a slower
moving vehicle ahead, the system will
reduce the vehicle speed so that your
vehicle follows the vehicle in front at the
selected distance.
The system automatically controls the
throttle and applies the brakes (up to
25% of vehicle braking power) if neces- sary.
The detection range of the sensor is
approximately 390 ft (120 m) ahead.
WARNING
.
This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’ s
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
. The system is primarily intended for use
on straight, dry, open roads with light
traffic. It is not advisable to use the
system in city traffic or congested areas.
. This system will not adapt automatically
to road conditions. This system should
be used in evenly flowing traffic. Do not
use the system on roads with sharp
curves, or on icy roads, in heavy rain or
in fog.
The distance sensor will not detect the
following objects:
.Stationary and slow moving vehicles
. Pedestrians or objects in the roadway

WARNING
. As there is a performance limit to the
distance control function, never rely
solely on the Intelligent Cruise Control
system. This system does not correct
careless, inattentive or absent-minded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Decele-
rate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing circumstances in order to maintain a
safe distance between vehicles.
. If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill and
sound a warning chime. To prevent the
vehicle from moving, the driver must
depress the brake pedal.
. The system may not detect the vehicle in
front of you in certain road or weather conditions. To avoid accidents, never use
the Intelligent Cruise Control system
under the following conditions:
—On roads where the traffic is heavy
or there are sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—During bad weather (rain, fog, snow,etc.)
When the windshield wiper is oper-
ated at the low speed (LO) or high
speed (HI) position, the Intelligent
Cruise Control system is automati-
cally canceled.
—When strong light (for example, atsunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere to
the system sensor
—On steep downhill roads (the vehi-cle may go beyond the set vehicle
speed and frequent braking may
result in overheating the brakes)
—On repeated uphill and downhillroads
—When traffic conditions make itdifficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
. Do not use the Intelligent Cruise Control
system if you are towing a trailer. The
system may not detect a vehicle ahead.
. In some road or traffic conditions, a
vehicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to
control the distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the ICC system
when it is not recommended in this
section.

ough. If this occurs, 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 is below
approximately 15 MPH (24 km/h) and a
vehicle is not detected ahead. The system
will also disengage when the vehicle goes
above the maximum set speed.
See“Approach warning” (P.5-46).
The following items are controlled in the
vehicle-to-vehicle distance control mode:
. 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 approximately 20 and 90 MPH
(32 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 driver, from the
vehicle ahead. The adjusting speed
range is up to the set speed. If the
vehicle ahead comes to a stop, the
vehicle decelerates to a standstill with-
in the limitations of the system. The
system will cancel once it judges a standstill with a warning chime.
. When the vehicle traveling ahead has
moved out from its lane of travel, the
vehicle-to-vehicle distance control
mode accelerates and maintains vehi-
cle 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 properly accel-
erate your vehicle when acceleration is
required for a lane change. Depress the brake pedal when deceleration 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 ICC system.
The driver sets the desired vehicle speed
based on the road conditions. The ICC
system maintains 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 controlling 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 and
the brake pedal depresses when braking is
performed by the ICC system.
When the brake operates, a noise may be
heard. 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 acceler-
ates 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 accel-
eration to the set vehicle speed or any time
Starting and driving5-43

5-46Starting and driving

.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 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
distance 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 vehi-
cles is increasing
. When a vehicle cuts in near your vehicle
The warning chime will not sound when:
. the vehicle approaches other vehicles
that are parked or moving slowly.
. the accelerator pedal is depressed,
overriding the system.
