Warning systems switch
FCW system operation
The FCW system will function at speeds of
approximately 10 MPH (15 km/h) and
above, when the system turns on.
The FCW system has an automatic setting
mode and a manual setting mode to turn
the system on. The setting mode can be
changed. In the automatic setting mode,
the FCW system is automatically turned on
when the ignition switch is pushed to the
ON position. When the FCW system is on,
the warning systems ON indicator light
*1
on the warning systems switch illuminates.
To cancel the FCW system, push thewarning systems switch. The warning
systems ON indicator light will turn off. To
turn on the system, push the warning
systems switch again.
When the warning systems switch is
pushed, the LDW and BSW systems will
also turn on or off simultaneously. See
“Lane Departure Warning (LDW) system”
(P.5-20) and
“Blind Spot Warning (BSW)
system” (P.5-27).
In the manual setting mode, you need to
push the warning systems switch to turn
on the system after the ignition switch is
pushed to the ON position.
The setting mode can be changed using
the warning systems switch. To change the
setting mode, push and hold the warning
systems switch for more than 4 seconds
when the warning systems ON indicator is
off. When the mode is changed, a chime
sounds and the lane departure warning
light (orange) flashes.
For the sensor maintenance, see “Intelli-
gent Cruise Control (ICC) system (FULL
SPEED RANGE)” (P.5-36). 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.

and could result in loss of vehicle control.
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:
— When the driver depresses the
accelerator pedal or the brake ped-
al.
— If the driver does not operate the
accelerator or brake pedal within
approximately 1 second.
BRAKE ASSIST

.The sensor will not detect:
— Pedestrians or objects in the road-
way
— Oncoming vehicles in the same lane
— Motorcycles traveling offset in the
travel lane as illustrated
WARNING
. This system 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.
. As there is a performance limit to the
Preview Function, never rely solely on
this system. This system does not
correct careless inattentive or absent-
minded driving, or overcome poor visi-
bility in rain, fog, or other bad weather.
Reduce vehicle speed by depressing the
brake pedal, in order to maintain a safe
distance between vehicles.
. The system may not detect the vehicle in
front of you in certain road or weather
conditions. The Preview Function may
not operate properly under the following
conditions. The vehicle is still driveable
under normal conditions and the Brake
Assist will operate.
—When rain, snow or dirt adhere to
the system sensor
—When strong light (for example, atsunrise or sunset) is directly shining
on the front of the vehicle
—Winding or hilly roads may causethe sensor to temporarily not detect
a vehicle in the same lane or may
detect objects or vehicles in other
lanes.
—Vehicle position in the lane maycause the sensor to temporarily not
detect a vehicle in the same lane or
may detect objects or vehicles in
other lanes.
