■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.
■Pre-collision brake assist
When the system determines that the possibility of a frontal co lli-
sion is high, the system applies greater braking force in relat ion to
how strongly the brake pedal is depressed.
■Pre-collision braking
If the system determines that the possibility of a frontal coll ision is
extremely high, the brakes are automatically applied to help av oid
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 wi th a
pedestrian is high and that there is sufficient space for the v ehicle
to be steered into within its lane, and the driver has begun ev asive
maneuver or steering, emergency steering assist will assist the
steering movements to help enhance the vehicle stability and fo r
lane departure prevention.

WARNING
■Emergency steering assist (for region A)
● As emergency steering assist operation will be canceled when the system
determines that lane departure prevention function has been com pleted.
● 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 stee ring 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 steering 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 steeri ng 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-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 ser ious 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 chassis 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 grille, 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

alert will operate even if the turn
signals are operating.
