PREVIEW FUNCTION (for Intelligent
Cruise Control system equipped
models)
The ICC system with the preview function
identifies the need to apply emergency
braking by sensing the vehicle ahead in
the same lane and the distance to the
vehicle ahead and relative speed from it, it
applies the brake pre-pressure before the
driver depresses the brake pedal and helps
improve brake response by reducing pedal
free play.
For more details, see“Brake assist ”later in
this section. The Distance Control Assist (DCA) system
brakes and moves the accelerator pedal
upward according to the distance from and
the relative speed of the vehicle ahead to
help assist the driver to maintain a
following distance.
WARNING
.
Always drive carefully and attentively
when using the Distance Control Assist
system. Read and understand the Own-
er’s Manual thoroughly before using the
DCA system. To avoid serious injury or
death, do not rely on the system to
prevent accidents or to control the
vehicle ’s speed in emergency situations.
Do not use the Distance Control Assist
system except in appropriate road and
traffic conditions.
. 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 with
a warning chime. To prevent the vehicle
from moving, the driver must depress
the brake pedal. .
The DCA system will not apply brake
control while the driver ’s foot is on the
accelerator pedal.

WARNING
.When the vehicle ahead detection in-
dicator light is not illuminated, system
will not control or warn the driver.
. Never place your foot under the brake
pedal. Your foot may be caught when the
system controls the brake.
. Depending on the position of the accel-
erator pedal, the system may not be able
to assist the driver to release the
accelerator pedal appropriately.
. If the vehicle ahead comes to a stand-
still, the vehicle decelerates to a stand-
still within the limitations of the system.
The system will release brake control
with a warning chime once it judges the
vehicle is at a standstill. To prevent the
vehicle from moving, the driver must
depress the brake pedal. (The system
will resume control automatically once
the system reaches 3 MPH (5 km/h)).
Overriding the system:
The following driver’ s operation overrides
the system operation. .
When the driver depresses the accel-
erator pedal even further while the
system is moving the accelerator pedal
upward, the DCA system control of the
accelerator 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
system is set, the DCA system will be
cancelled.
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 DCA system display. Decelerate by
depressing the brake pedal to maintain a
safe vehicle distance if:
. The chime sounds.
. The vehicle ahead detection indicator
blinks.
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 vehicles that are
parked or moving slowly.

Sensor maintenance
How to handle the sensor:
The sensor for the DCA system is common
with Intelligent Cruise Control and is
located below the front bumper.
To handle the sensor, see“Intelligent
Cruise Control (ICC) system” earlier in this
section. The Forward Collision Warning (FCW) sys-
tem will warn the driver by the vehicle
ahead detection indicator light and chime
when your vehicle is getting close to the
vehicle ahead in the traveling lane.
The FCW system will function when your
vehicle is driven at speeds of approxi-
mately 10 MPH (15 km/h) and above.

For the sensor maintenance, see “Intelli-
gent Cruise Control (ICC) system” earlier in
this section. The Intelligent Brake Assist (IBA) system
warns the driver by a warning light and
chime when there is a risk of a collision
with the vehicle ahead in the traveling lane
and the driver must take avoidance action
immediately. The system helps reduce the
rear-end collision speed by applying the
brakes when the system judges that the
collision cannot be prevented.
The IBA system will function when your
vehicle is driven at speeds of approxi-
mately 10 MPH (15 km/h) and above, and
when your vehicle is driven at speeds
approximately 10 MPH (15 km/h) faster
than the vehicle ahead.

WARNING
.While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
. 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.
PREVIEW FUNCTION (Intelligent
Cruise Control system equipped
models)
When the Preview Function identifies the
need to apply emergency braking by
sensing a vehicle ahead in the same lane
and the distance and relative speed from
it, it applies the brake pre-pressure before
the driver depresses the brake pedal and
helps improve brake response by reducing
pedal free play. .
This system will not operate when the
vehicle is moving at approximately 20
MPH (32 km/h) or less.
. The pre-pressure function ceases when
the following conditions are met:
1) When the driver depresses the
accelerator pedal or the brake
pedal.
2) If the driver does not operate the accelerator or brake pedal within
approximately 1 second.
