4-5. Using the driving support systems
■Pre-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.
“BRAKE!”
■Pre-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.
■Pre-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.
■Emergency steering assist (for
region A)
If the system determines that the
possibility of a collision with a
pedestrian is high and that there is
sufficient space for the vehicle to be
steered into within its lane, and the
driver has begun evasive maneuver
or steering, emergency steering
assist will assist the steering move-
ments to help enhance the vehicle
stability and for lane departure pre-
vention. During operation, the indi-
cator will illuminate in green.
■Intersection right/left turn
assistance (for region A)
If the system determines that there
is a high possibility of a collision in
the following situations, it will assist
with Pre-collision warning and, if
necessary Pre-collision braking.
Depending on the configuration of
the intersection, it may not be pos-
sible to support.

intersection and cross the path of

When you turn right/left, pedes-
trian is detected in the forward
direction and estimated to enter
your vehicle’s path (bicyclists are
not detected.)
WARNING
■Limitations of the pre-collision system
●The 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.
●Although 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. 2 2 4
• Conditions under which the system may not operate properly: P. 2 2 5
●Do 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.
■Pre-collision braking
●When the pre-collision braking
function is operating, a large amount of braking force will be applied.
●If 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.
●The 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.

4-5. Using the driving support systems
WARNING
●In 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.
●If 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.
■Emergency steering assist (for
region A)
●As emergency steering assist oper- ation will be canceled when the sys-
tem determines that lane departure prevention function has been com-pleted.
●Emergency steering assist may not operate or may be cancel in the fol-
lowing cases as the system may determine the driver is taking actions.
• If the accelerator pedal is being depressed strongly, the steering
wheel is being operated sharply, the brake pedal is being depressed or the turn signal lever is being
operated. In this case, the system may determine that the driver is tak-ing evasive action and the emer-
gency steering assist may not operate.
• In some situations, while the emer- gency steering assist is operating, operation of the function may be
canceled if the accelerator pedal is depressed strongly, the steering wheel is operated sharply or the
brake pedal is being depressed and the system determines that the driver 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.
■When 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:
●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 engine running and the tires are allowed to rotate freely
●When inspecting the vehicle using a drum tester such as a chassis dynamometer or speedometer tes-
ter, or when using an on vehicle wheel balancer
●When a strong impact is applied to the front bumper or front grille, due to an accident or other reasons
●If the vehicle cannot be driven in a stable manner, such as when the
vehicle 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

■Enabling/disabling the pre-col-
lision system
The pre-collision system can be
enabled/disabled on ( P.457)
of the multi-information display.
The system is automatically enabled
each time the engine 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.
“Pre-Collision System OFF”
■Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on ( P.457) of
the multi-information display.
The warning timing setting is retained
when the engine switch is turned off.
However, if the pre-collision system is
disabled and re-enabled, the operation
timing will return to the default setting
(middle).
For region A: If the pre-collision warn-
ing timing is changed, emergency
steering assist timing will also be
changed accordingly.
If late is selected, emergency steering
assist would not operate in case of an
emergency.

●Emergency steering assist (for region A)
When the turn signal lights are flashing, emergency steering as sist will not operate in

• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.

■Object 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.225) The illustration shows an image of detectable objects.

■Situations in which the system may
not operate properly

ing, an object may not be detected by the radar sensor and front camera, preventing the system from operating
properly: • When a detectable object is approaching your vehicle
• When your vehicle or a detectable object is wobbling• If a detectable object makes an abrupt
maneuver (such as sudden swerving, acceleration or deceleration)• When your vehicle approaches a
detectable object rapidly • When a detectable object is not directly in front of your vehicle
• When a detectable object is near a wall, fence, guardrail, manhole cover,
