ahead
System operation
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 and/or vibration may be felt. 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:

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 condi-
tions and the control is automatically can-
celed.
.When the vehicle ahead is not detected
and your vehicle is traveling below the
speed of 15 MPH (24 km/h)
. When the system judges the vehicle is at
standstill
. When the shift lever is not in the D (Drive)
or manual shift mode
. When the parking brake is applied
. When the SNOW mode switch is pushed
on.
. When the 4WD shift switch is in the 4H
or 4L position (for 4WD models)
. When the VDC system is turned off
. When ABS or VDC (including the traction
control system) operates

. When the radar signal is temporarily
interrupted
Vehicle-to-vehicle distance control
mode limitations
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
. 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 con-
gested areas.
. This system will not adapt automati-
cally 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.
. As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absent-minded driving, or over- come poor visibility in rain, fog, or
other bad weather. Decelerate the
vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain 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.
. Always pay attention to the opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The vehicle-to-vehicle
distance control mode of the ICC
system may not be able to maintain
the selected distance between vehi-
cles (following distance) or selected
vehicle speed under some circum-
stances.
. Normally when controlling the dis-
tance to a vehicle ahead, this system
automatically accelerates or decele-
rates your vehicle according to the
speed of the vehicle ahead. Depress

ing circumstances in order to main-
tain a safe distance between vehicles. .
The system may not detect the
vehicle in front of you in certain road
or weather conditions. To avoid ac-
cidents, never use the DCA system
under the following conditions:
— On roads with sharp curves
— On slippery road surfaces such as on ice or snow, etc.
— On off-road surfaces such as on sand or rock, etc.
— During bad weather (rain, fog, snow, etc.)
— When rain, snow or dirt adhere to the system sensor
— On steep downhill roads (fre- quent braking may result in over-
heating the brakes)
— On repeated uphill and downhill roads
— When towing a trailer or other vehicle
. 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 accel-
erator pedal. Always stay alert and avoid using the DCA system when it
is not recommended in this section.
The radar sensor will not detect the follow-
ing objects:
. Stationary and slow moving vehicles
. Pedestrians or objects in the roadway
. Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
The following are some conditions in which
the sensor cannot detect the signals:

. If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even with
light pedal force.
WARNING
The Brake Assist is only an aid to assist
braking operation 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.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that
stopping distances on slippery sur- faces will be longer than on normal
surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered roads,
or if you are using tire chains. Always
maintain a safe distance from the
vehicle in front of you. Ultimately,
the driver is responsible for safety.
. Tire type and condition may also
affect braking effectiveness.
— When replacing tires, install the specified size of tires on all four
wheels.
— When installing a spare tire, make sure that it is the proper size and
type as specified on the Tire and
Loading Information label. See
“Tire and loading information la-
bel” (P.10-13).
— For detailed information, see “Wheels and tires” (P.8-27).
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during
hard braking or when braking on slippery
surfaces. The system detects the rotation
speed at each wheel and varies the brake
fluid pressure to prevent each wheel from
locking and sliding. By preventing each
wheel from locking, the system helps the
