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 and if
the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill. 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 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.5-62).
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.
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.

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
