WARNING
Failure to follow the warnings and
instructions for proper use of the PFCW
system could result in serious injury or
death.
.The PFCW system helps warn the
driver before a collision but will not
avoid a collision. It is the driver’s
responsibility to stay alert, drive
safely and be in control of the
vehicle at all times.
The PFCW system can help alert the driver
when there is a sudden braking of a second
vehicle traveling in front of the vehicle ahead in
the same lane.

the obstacle is less than 11.8 in (30 cm) away,
the tone will sound continuously.
Keep the corner/center sensors (located on the
bumper fascia) free from snow, ice and large
accumulations of dirt (do not clean the sensors
with sharp objects) . If the sensors are covered, it
will affect the accuracy of the sonar system.
The sensitivity level of the corner/center sensors
can be adjusted (higher or lower) in the Sonar
setting display. (See “Sonar settings” (P.4-27) .)
The intermittent tone will stop in 3 seconds
when an obstacle is detected by only the corner
sensor and the distance does not change.

SONAR INDICATOR
With the “Sonar Display” key ON in the “Sonar”
settings, when the corner/center sensors detect
obstacles near the bumper, a tone will sound
and the sonar indicator will appear in the center
display
*1. When the RearView Monitor is
displayed, the sonar indicator will appear in the
upper corner of the display
*2.
The sonar indicators
*Aand*Bindicate the
position of the object and the distance to the
object with its color and rate of blinking.
When an object is detected, the indicator
(green) appears and blinks (the tone sounds
intermittently) . When the vehicle moves closer
to the object, the color of the indicator turns
yellow and the rate of blinking increases (the
rate of the tone increases) . When the bumper is
very close to the object, less than 11.8 in (30
cm) away, the indicator stops blinking and turns
red (the tone sounds continuously) .
When the RearView Monitor is displayed,
the colors of the sonar indicator and the
distance guide lines in the rear view
indicate different distances to the object.
The sonar indicator can be turned off in the
sonar setting display. (See “Sonar settings”
(P.4-27) .) When the sonar indicator is off, only
a tone sounds when the sonar detect obstacles.

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
vehicle control during braking on
slippery 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 label” (P.10-12) .
— For detailed information, see “Wheels and tires” (P.8-30) .
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 driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and does not
indicate a malfunction. If the computer senses
a malfunction, it switches the ABS off and
