WARNING
■Pre-collision braking
● When the pre-collision braking function is operating, a large a mount of
braking force will be applied.
● If the vehicle is stopped by the operation of the pre-collision braking func-
tion, the pre-collision braking function operation will be canceled after
approximately 2 seconds. Depress the brake pedal as necessary.
● The pre-collision braking function may not operate if certain operations 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 taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.
● In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the syst em deter-
mines that the driver is taking evasive action.
● If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.
■ Emergency steering assist
● As emergency steering assist operation will be canceled when th e system
determines that lane departure prevention function has been completed.
● Emergency steering assist may not operate or may be cancel in the follow-
ing cases as the system may determine the driver is taking acti ons.
• If the accelerator pedal is being depressed strongly, the steering wheel is being operated sharply, the brake pedal is being depressed o r the
turn signal lever is being operated. In this case, the system m ay deter-
mine that the driver is taking evasive action and the emergency steering
assist may not operate.
• In some situations, while the emergency steering assist is ope rating,
operation of the function may be canceled if the accelerator pe dal is
depressed strongly, the steeri ng wheel is operated sharply or t he brake
pedal is being depressed and the system determines that the dri ver is
taking evasive action.
• When the emergency steering assist is operating, if the steering wheel
is held firmly or is operated in the opposite direction to that which the
system is generating torque, the function may be canceled.

WARNING
■When to disable the pre-collision 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:
● When the vehicle is being towed
● When your vehicle is towing another vehicle
● When transporting the vehicle via truck, boat, train or similar means of
transportation
● When the vehicle is raised on a lift with the hybrid system on and the tires
are allowed to rotate freely
● When inspecting the vehicle using a drum tester such as a chass is dyna-
mometer or speedometer tester, or when using an on vehicle whee l bal-
ancer
● When a strong impact is applied to the front bumper or front gr ille, due to
an accident or other reasons
● If the vehicle cannot be driven in a stable manner, such as when the vehi-
cle has been in an accident or is malfunctioning
● When the vehicle is driven in a sporty manner or off-road
● When the tires are not properly inflated
● When the tires are very worn
● When tires of a size other than specified are installed
● When tire chains are installed
● When a compact spare tire or an emergency tire puncture repair kit is used
● If equipment (snow plow, etc.) that may obstruct the radar sens or or front
camera is temporarily installed to the vehicle

■Enabling/disabling the pre-collision system
The pre-collision system c an be enabled/disabled on ( P. 1 1 2 )
of the multi-information display.
The system is automatically enabled each time the power switch is
turned to ON mode.
If the system is disabled, the
PCS warning light will turn on
and a message will be dis-
played on the multi-information
display.
■Changing the pre-colli sion warning timing
The pre-collision warning timing can be changed on ( P. 1 1 2 )
of the multi-information display.
The warning timing setting is retained when the power switch is turned
off. However, if the pre-collision system is disabled and re-en abled, the
operation timing will return to the default setting (middle).
If the pre-collision warning timing is changed, e mergency steering
assist timing will also b e changed accordingly.
If late is selected, emergency st eering assist would not operate in
case of an emergency.

■Operational conditions for each pre-collision function
The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision with a detected object is high.
The system may not operate in the following situations:
• If a 12-volt battery terminal has been disconnected and reconn ected and
then the vehicle has not been driven for a certain amount of ti me
• If the shift lever is in R
• When the VSC OFF indicator is illuminated (only the pre-collis ion warning
function will be operational)
The operation speeds and operation cancellation for each functi on is
listed below.
● Pre-collision warning
While the pre-collision warning function is operating, if the s teering wheel is
operated heavily or suddenly, the pre-collision warning may be cancelled.
● Pre-collision brake assist

The system detects objects based on
their size, profile, motion, etc. However,
an object may not be detected depending
on the surrounding brightness and the
motion, posture, and angle of the
detected object, preventing the system
from operating properly. (P. 257)
The illustration shows an image of detect-
able objects.

■Conditions under which the system may operate even if there is no pos-
sibility of a collision
● In some situations such as the following, the system may determ ine that
there is a possibility of a frontal collision and operate.
• When passing a detectable object, etc.
• When changing lanes while overtaking a detectable object, etc.
• When rapidly closing on a detectable object, etc.
• When approaching objects on the roadside, such as detectable o bjects,
guardrails, utility poles, trees, or walls
• When there are patterns or paint in front of your vehicle that may be mis-
taken for a detectable object
• When the front of your vehicle is hit by water, snow, dust, et c.
• When approaching a detectable
object in an adjacent lane or on the
roadside, such as when changing the
course of travel or driving on a wind-
ing road
• When there is a detectable object or other object by the roadside at the
entrance of a curve
• When overtaking a detectable object that is changing lanes or making a
right/left turn
• When passing a detectable object in an oncoming lane that is stopped to
make a right/left turn

2564-5. Using the driving support systems
• When a detectable object approaches very close and then stops before
entering the path of your vehicle
• If the front of your vehicle is raised or lowered, such as whe n on an
uneven or undulating road surface
• When driving on a road surrounded by a structure, such as in a tunnel or
on an iron bridge
• When there is a metal object (manhole cover, steel plate, etc. ), steps, or a
protrusion in front of your vehicle
• When approaching an electric toll gate barrier, parking area b arrier, or
other barrier that opens and closes
• When using an automatic car wash
• When driving through steam or smoke
• When driving near an object that reflects radio waves, such as a large
truck or guardrail
• When driving near a TV tower, broadcasting station, electric power plant, radar equipped vehicles, etc., or other location where strong r adio waves
or electrical noise may be present
• When there are many things which can reflect the radio waves of the radar in the vicinity (tunnels, truss bridges, gravel roads, sn ow covered
road that have tracks, etc.)
• While making a right/left turn, when an oncoming vehicle or a crossing
pedestrian has already exited the path of your vehicle
• While making a right/left turn, closely in front of an oncomin g vehicle or a
crossing pedestrian.
• While making a right/left turn, when an oncoming vehicle or a crossing
pedestrian stops before entering the path of your vehicle
• When passing under an object (road
sign, billboard, etc.)
• When driving through or under objects that may contact your vehicle,
such as thick grass, tree branches, or
a banner
