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

*

A

detects 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 under
most conditions:
. Stationary and slow moving vehicles
. Pedestrians or objects in the roadway

. Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel

lane

This system will not automatically brake
the vehicle to a stop.

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.

. Although the brake operation is con-

trolled by the system, the system does
not automatically stop the vehicle. If the
vehicle speed falls below approximately
20 MPH (32 km/h), the Intelligent Cruise
Control system is automatically canceled
and a warning chime sounds. (The brake
control is also canceled.)

. 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, at

sunrise 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 downhill

roads

— When traffic conditions make it

difficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration

. 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.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION

Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance. The
vehicle-to-vehicle distance control mode of
the Intelligent Cruise Control (ICC) system
may not be able to maintain the selected
distance between vehicles (following dis-
tance) or selected vehicle speed under
some circumstances.

The vehicle-to-vehicle distance control
mode uses a sensor

*

A

located on the

front of the vehicle to detect vehicles

Starting and driving

5-27

Starting and driving

traveling ahead. The sensor generally
detects the signals returned from the
reflectors on a vehicle ahead. Therefore, if
the sensor cannot detect the reflector on
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 of the vehicle ahead

is positioned high on the vehicle
(trailer, etc.)

. When the reflector on the vehicle ahead

is missing, damaged or covered

. When the reflector of the vehicle ahead

is covered with dirt, snow and road
spray

. When the snow or road spray from

traveling 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 trunk of
your vehicle

The ICC system is designed to automati-
cally check the sensor

’s operation within

the limitations of the system. When the

sensor is covered with dirt or obstructs, the
system will automatically be canceled. If
the sensor is covered with ice, a transpar-
ent 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
check and 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 slower vehicle ahead; the system will
decelerate the vehicle as necessary. How-
ever, the ICC system can only apply up to
25% of the vehicles total braking power.
This system should only be used when
traffic conditions allow vehicle speeds to
remain fairly constant or when vehicle
speeds change gradually. If a vehicle
moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decele-
rates, the distance between vehicles may
become closer because the ICC system
cannot decelerate the vehicle quickly en-
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 falls below
approximately 20 MPH (32 km/h). The
system will also disengage below the 20
MPH (32 km/h) cut-off speed or over the
maximum set speed.

See

“Approach warning” (P.5-37).

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 25 and 90 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 driver, from the
vehicle ahead. The adjusting speed
range is between approximately 20
MPH (32 km/h) and up to 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 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.

SSD0252

The detection zone of the ICC sensor is
limited. A vehicle ahead must be in the
detection zone for the vehicle-to-vehicle
distance detection mode to maintain the
selected distance from the vehicle ahead.

A vehicle ahead may move outside of the
detection zone due to its position within
the same lane of travel. Motorcycles may
not be detected in the same lane ahead if
they are traveling offset from the centerline
of the lane. A vehicle that is entering the
lane ahead may not be detected until the
vehicle has completely moved into the
lane.

If this occurs, the ICC system may

warn you by blinking the system indicator

and sounding the chime. The driver may
have to manually control the proper
distance away from vehicle traveling
ahead.

SSD0253

When driving on some roads, such as
winding, hilly, curved, narrow roads, or
roads which are under construction, the
ICC sensor may detect vehicles in a
different lane, or may temporarily not
detect a vehicle traveling ahead. This may
cause the ICC system to decelerate or
accelerate the vehicle.

The detection of vehicles may also be
affected by vehicle operation (steering
maneuver or traveling position in the lane,
etc.) or vehicle condition.

If this occurs, the

ICC system may warn you by blinking the
system indicator and sounding the chime
unexpectedly. You will have to manually

control the proper distance away from the
vehicle traveling ahead.

SSD0254

When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC will adjust the speed to
maintain the distance, selected by the
driver, from the vehicle ahead. If the
vehicle ahead changes lanes or exits the
freeway, the ICC system will accelerate and
maintain the speed up to the set speed.
Pay attention to the driving operation to
maintain control of the vehicle as it
accelerates to the set speed.

The vehicle may not maintain the set speed
on winding or hilly roads. If this occurs,
you will have to manually control the
vehicle speed.

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
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

the ICC system is in operation, the system
controls the distance to that vehicle.

SSD0611

When passing another vehicle, the set
speed indicator will flash when the vehicle
speed exceeds 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.

Even though your vehicle speed is set in
the ICC system, you can depress the
accelerator pedal when it is necessary to
accelerate 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 MAIN switch off. Both the MAIN

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 ACCELERATE/RE-

SUME switch. The set vehicle speed
will increase by approximately 5 MPH
(5 km/h for Canada).

. Push, then quickly release the ACCEL-

ERATE/RESUME 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

vehicle attains the desired speed, push
the COAST/SET switch and release it.

. Push, then quickly release the COAST/

SET switch. Each time you do this, the
set speed will decrease by approxi-
mately 1 MPH (1 km/h for Canada).

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).

SSD0612

How to change the set distance to
the vehicle ahead

The distance to the vehicle ahead can be
selected at any time depending on the
traffic conditions.

Each time the DISTANCE switch

*

A

is

pushed, the set distance will change to
long, middle, short and back to long again
in that sequence.

SSD0613D

. 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:
. Your vehicle approaches other vehicles

that are parked or moving slowly.

. 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

*

A

which 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 detect
these reflectors when the vehicle is driven
on winding roads, hilly roads or when
entering or exiting a curve. The ICC sensor
may also detect reflectors on narrow roads
or in road construction 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 condition (for example, if a vehicle
is being driven with some damage).

Automatic cancellation

A chime sounds under the following con-
ditions and the control is automatically
canceled.
. When the vehicle speed falls below

approximately 20 MPH (32 km/h)

. When the selector lever is not in the D

(Drive), DS (Drive Sport) or manual shift
mode

. When the windshield wipers are oper-

ated at low speed (LO) or high speed
(HI)

. When the SNOW mode switch is turned
