system completely off.
When the ignition switch is placed in the
OFF position, the system is also automati-
cally 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.
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)” (P.5-92).
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 color
of the cruise indicator changes to green and
set vehicle speed indicator comes on.) Take
your foot off the accelerator pedal. Your
vehicle will maintain the set speed.
. To pass another vehicle, depress the
accelerator 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 vehi-
cle speed. To cancel the preset speed,
use any of the
following methods:
1. Push the CANCEL switch. The vehicle speed indicator will turn off.
2. Tap the brake pedal. The vehicle speed indicator will turn off.
3. Turn the MAIN switch off. Both the cruise indicator and vehicle speed indi-
cator will turn off.
To reset at a faster cruising speed, use one
of the following three methods:
1. Depress the accelerator pedal. When the vehicle attains the desired speed, push
and release the SET/COAST (-) switch.
2. Push and hold the RESUME/ACCELER- ATE (+) switch. When the vehicle attains
the desired speed, release the switch.
3. Push, then quickly release the RESUME/ ACCELERATE (+) 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 three methods:
1. Lightly tap the brake pedal. When the
vehicle attains the desired speed, push
the SET/COAST (-) switch and release it.
2. Push and hold the SET/COAST (-) switch. Release the switch when the
vehicle slows down to the desired speed.

The DCA system helps assist the driver to
keep a following distance to the vehicle
ahead by braking and moving the accelera-
tor pedal upward in the normal driving
condition.
When a vehicle ahead is detected:
The vehicle ahead detection indicator ap-
pears. When the vehicle approaches a vehicle
ahead:
.
If the driver’s foot is not on the accel-
erator pedal, the system activates the
brakes to decelerate smoothly as neces-
sary. If the vehicle ahead comes to a
stop, the vehicle decelerates to a stand-
still within the limitations of the system.
. If the driver’s foot is on the accelerator
pedal, the system moves the accelerator
pedal upward to assist the driver to
release the accelerator pedal.
When brake operation by the driver is
required:
The system alerts the driver by a warning
chime and blinking the vehicle ahead detec- tion indicator. If the driver’s foot is on the
accelerator pedal after the warning, the
system moves the accelerator pedal upward
to assist the driver to switch to the brake
pedal.
NOTE:
.
The stop lights of the vehicle come on
when braking is performed by the DCA
system.
. When the brake operates, a noise may be
heard. This is not a malfunction.
Overriding the system:
The following driver’s operation overrides
the system operation.
. When the driver depresses the accelera-
tor pedal even further while the system is
moving the accelerator pedal upward,
the DCA system control of the accel-
erator pedal is canceled.
. When the driver’s foot is on the accel-
erator pedal, the brake control by the
system is not operated.
. When the driver’s foot is on the brake
pedal, neither the brake control nor the
alert by the system operates.
. When the Intelligent Cruise Control (ICC)
system is set, the DCA system will be
inactive.

FEB SYSTEM OPERATION
The FEB system operates at speeds above
approximately 3 MPH (5 km/h).
If a risk of a forward collision is detected, the
FEB system will provide the first warning to
the driver by flashing the driver assist system
forward indicator (orange)
and the vehicle
ahead detection indicator (orange), and
providing an audible warning. In addition,
the FEB system pushes the accelerator
pedal up. If the driver releases the accel-
erator pedal, then the system applies partial
braking.
If the driver applies the brakes quickly and
forcefully after the warning, and the FEB
system detects that there is still the possi-
bility of a forward collision, the system will
automatically increase the braking force.
If a forward collision is imminent and the
driver does not take action, the FEB system
issues the second visual (red) and audible
warning and automatically applies harder
braking.
NOTE:
The vehicle’s stop lights come on when
braking is performed by the FEB system.
Depending on vehicle speed and distance to
the vehicle ahead, as well as driving and
roadway conditions, the system may help
the driver avoid a forward collision or may

help mitigate the consequences of a collision
should one be unavoidable.
If the driver is handling the steering wheel,
accelerating or braking, the FEB system will
function later or will not function.
The automatic braking will cease under the
following conditions:
.When the steering wheel is turned as far
as necessary to avoid a collision.
. When the accelerator pedal is depressed.
. When there is no longer a vehicle de-
tected ahead.
If the FEB system has stopped the vehicle,
the vehicle will remain at a standstill for
approximately 2 seconds before the brakes
are released.

FEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the FEB system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
. The FEB system cannot detect all
vehicles under all conditions.
. The radar sensor does not detect the
following objects:
— Pedestrians, animals or obstacles in the roadway
— Oncoming vehicles
— Crossing vehicles
. The radar sensor has some perfor-
mance limitations. If a stationary
vehicle is in the vehicle’s path, the
FEB system will not function when
the vehicle is driven at speeds over
approximately 45 MPH (70 km/h).
. The radar sensor may not detect a
vehicle ahead in the following condi-
tions:
— Dirt, ice, snow or other material covering the radar sensor. — Interference by other radar
sources.
— Snow or road spray from travel- ing vehicles.
— If the vehicle ahead is narrow (e.g. motorcycle)
— When driving on a steep downhill slope or roads with sharp curves.
. In some road or traffic conditions, the
FEB system may unexpectedly push
the accelerator pedal up or apply
partial braking. When acceleration is
necessary, continue to depress the
accelerator pedal to override the
system.
. Braking distances increase on slip-
pery surfaces.
. The system is designed to automati-
cally check the sensor’s functionality,
within certain limitations. The system
may not detect some forms of ob-
struction of the sensor area such as
ice, snow, stickers, for example. In
these cases, the system may not be
able to warn the driver properly. Be
sure that you check, clean and clear
the sensor area regularly.
. Excessive noise will interfere with the
warning chime sound, and the chime

SYSTEM MAINTENANCE
The sensoris located behind the lower
grille of the front bumper.
To keep the system operating properly, be
sure to observe the following:
. Always keep the sensor area of the front
bumper clean.
. Do not strike or damage the areas around
the sensor.
. Do not cover or attach stickers or similar
objects on the front bumper near the
sensor area. This could cause failure or
malfunction.
. Do not attach metallic objects near the
sensor area (brush guard, etc.). This
