5 5-5. Using the driving support systems
Driving
*: If equipped
The system can detect the follow-
ing:
Vehicles
Bicyclists
Pedestrians
QPre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a
warning message will be displayed
on the multi-information display to
urge the driver to take evasive
action.
QPre-collision brake assist
When the system determines that
the possibility of a frontal collision is
high, the system applies greater
braking force in relation to how
strongly the brake pedal is
depressed.
QPre-collision braking
If the system determines that the
possibility of a frontal collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.
PCS (Pre-Collision Sys-
tem)
*
The pre-collision system uses
a radar sensor and front cam-
era to detect objects (P.311)
in front of the vehicle. When
the system determines that the
possibility of a frontal collision
with an object is high, a warn-
ing operates to urge the driver
to take evasive action and the
potential brake pressure is
increased to help the driver
avoid the collision. If the sys-
tem determines that the possi-
bility of a frontal collision with
an object is extremely high,
the brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.
The pre-collision system can be
disabled/enabled and the warn-
ing timing can be changed.

WARNING
QLimitations of the pre-collision system
OThe driver is solely responsible for safe driving. Always drive safely, taking care to observe your sur-
roundings. Do not use the pre-collision system instead of normal braking opera-
tions under any circumstances. This system will not prevent colli-sions or lessen collision damage or
injury in every situation. Do not overly rely on this system. Failure to do so may lead to an accident,
resulting in death or serious injury.
OAlthough this system is designed to
help avoid a collision or help reduce the impact of the collision, its effec-tiveness may change according to
various conditions, therefore the system may not always be able to achieve the same level of perfor-
mance. Read the following conditions care-fully. Do not overly rely on this sys-
tem and always drive carefully.
• Conditions under which the system may operate even if there is no pos-
sibility of a collision: P.315
• Conditions under which the system may not operate properly: P.316
ODo not attempt to test the operation of the pre-collision system yourself.
Depending on the objects used for testing (dummies, cardboard objects imitating detectable objects,
etc.), the system may not operate properly, possibly leading to an accident.
QPre-collision braking
OWhen the pre-collision braking
function is operating, a large amount of braking force will be applied.
OIf the vehicle is stopped by the operation of the pre-collision brak-ing function, the pre-collision brak-
ing function operation will be canceled after approximately 2 sec-onds. Depress the brake pedal as
necessary.
OThe pre-collision braking function
may not operate if certain opera- tions are performed by the driver. If the accelerator pedal is being
depressed strongly or the steering wheel is being turned, the system may determine that the driver is tak-
ing evasive action and possibly pre- vent the pre-collision braking function from operating.
OIn some situations, while the pre-collision braking function is operat-
ing, operation of the function may be canceled if the accelerator pedal is depressed strongly or the steer-
ing wheel is turned and the system determines that the driver is taking evasive action.
OIf the brake pedal is being depressed, the system may deter-
mine that the driver is taking eva- sive action and possibly delay the operation timing of the pre-collision
braking function.
QWhen to disable the pre-colli-
sion system
In the following situations, disable the system, as it may not operate prop-
erly, possibly leading to an accident resulting in death or serious injury:
OWhen the vehicle is being towed
OWhen your vehicle is towing another vehicle
OWhen transporting the vehicle via truck, boat, train or similar means of
transportation
OWhen the vehicle is raised on a lift
with the hybrid system on and the tires are allowed to rotate freely

QEnabling/disabling the pre-col-
lision system
The pre-collision system can be
enabled/disabled on the screen
( P.184) of the multi-information
display.
The system is automatically enabled
each time the power switch is turned to
ON.
If the system is disabled, the PCS
warning light will turn on and a
message will be displayed on the
multi-information display.
QChanging the pre-collision
warning timing
The pre-collision warning timing
can be changed on the screen
( P.184) of the multi-information
display.
The warning timing setting is retained
when the power switch is turned to
OFF. However, if the pre-collision sys-
tem is disabled and re-enabled, the
operation timing will return to the
default setting (middle).
WARNING
OWhen inspecting the vehicle using a drum tester such as a chassis
dynamometer or speedometer tes- ter, or when using an on vehicle wheel balancer
OWhen a strong impact is applied to the front bumper or front grille, due
to an accident or other reasons
OIf the vehicle cannot be driven in a
stable manner, such as when the vehicle has been in an accident or is malfunctioning
OWhen the vehicle is driven in a sporty manner or off-road
OWhen the tires are not properly inflated
OWhen the tires are very worn
OWhen tires of a size other than specified are installed
OWhen tire chains are installed
OWhen a compact spare tire or an
emergency tire puncture repair kit is used
OIf equipment (snow plow, etc.) that may obstruct the radar sensor or front camera is temporarily installed
to the vehicle

QOperational conditions
The pre-collision system is enabled and the system determines that the possibility of a frontal collision with a detected object is high.Each function is operational at the following speed
OPre-collision warning
OPre-collision brake assist
OPre-collision braking
The system may not operate in the following situations:
OIf a 12-volt battery terminal has been disconnected and reconnected and then the vehicle has not been driven for a certain amount of time
OIf the shift lever is in R
OWhen the VSC OFF indicator is illuminated (only the pre-collision warning function will be operational)
QObject detection function
The system detects objects based on
their size, profile, motion, etc. However, an object may not be detected depend-
ing on the surrounding brightness and the motion, posture, and angle of the
detected object, preventing the system from operating properly. ( P.316)

*: If equipped
LTA (Lane Tracing
Assist)
*
While driving on a road with
clear white (yellow) lane lines,
the LTA system warns the
driver if the vehicle may devi-
ate from the current lane or
course
*, and also can slightly
operate the steering wheel to
help avoid deviation from the
lane or course
*. Also, while the
dynamic radar cruise control
with full-speed range is operat-
ing, this system will operate
the steering wheel to maintain
the vehicle’s lane position.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front cam-
era. Additionally, it detects pre-
ceding vehicles using the front
camera and radar.
*: Boundary between asphalt and the
side of the road, such as grass,
soil, or a curb
