Driving
high, the brakes are automatically
applied to help avoid the collision or
reduce the impact of the collision.
■Emergency steering assist
If the system determines that the
following conditions are met, assis-
tance will be provided to help
enhance vehicle stability and pre-
vent lane departure. During assis-
tance, in addition to the pre-
collision warning, the following icon
will be displayed on the multi-infor-
mation display.
 The possibility of a collision is
high
 There is sufficient space within
the lane to perform evasive
steering maneuvers
 The driver is operating the steer-
ing wheel
During assistance, the pre-collision
warning will operate and a mes-
sage will be displayed to warn the
driver.
■Intersection collision avoid-
ance support (left/right turn)
In situations such as the following,
if the system determines that the
possibility of a collision is high, the
pre-collision warning and pre-colli-
sion braking will operate. Depend-
ing on the intersection, assistance
may not operate correctly.
 When turning left/right at an
intersection and crossing the
path of an oncoming vehicle
 When turning left/right and an
oncoming pedestrian or bicycle
is detected
■Intersection collision avoid-
ance support (crossing vehi-
cles)
At an intersection, etc., if the sys-
tem determines that the possibility
of a collision with an approaching
vehicle or motorcycle is high, the
pre-collision warning and pre-colli-
sion braking will operate. Depend-
ing on the intersection, assistance
may not operate correctly.

■Acceleration Suppression at
Low Speed
When driving at a low speed, if the
accelerator pedal is strongly
depressed and the system deter-
mines that there is a possibility of a
collision, EV system output will be
restrained or the brakes will be
applied weakly to restrict accelera-
tion. During operation, a buzzer will
sound and a warning indicator and
message will be displayed on the
multi-information display.
“Accelerator Pedal is Pressed”
WARNING
■Pre-collision braking
●When the pre-collision braking function is operating, a large amount of braking force will be
applied.
●Pre-collision braking function is not intended for remain stopped. If the vehicle is stopped by pre-collision
braking function, the driver should operate the brakes 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.
●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 brake control.
■Acceleration Suppression at Low Speed
If the steering wheel is being turned,
the system may determine that the driver is taking evasive action and possibly prevent the Acceleration
Suppression at Low Speed function from operating.
■Emergency steering assist
●The emergency steering assist will be canceled when the system
determines that lane departure pre- vention control has completed.
●Depending on operations per-formed by the driver, emergency steering assist may not operate or
operation may be canceled.
• If the accelerator pedal is
depressed strongly, the steering wheel is turned heavily, the brake pedal is depressed, or the turn sig-
nal lever is operated, the system may determine that the driver is tak-ing evasive action and the emer-
gency steering assist may not operate.

■Situations in which the system may
operate even though the possibility of a collision is not high
●In certain situations, such as the fol-lowing, the system may determine that the possibility of a collision is high
and operate: • When passing a detectable object• When changing lanes while overtak-
ing a detectable object • When suddenly approaching a detect-able object
• When approaching a detectable object or other object on the roadside, such as guardrails, utility poles, trees,
walls, etc. • When there is a detectable object or other object by the roadside at the
entrance of a curve
• When there are patterns or a painting
ahead of the vehicle that may be mis- taken for a detectable object• When passing a detectable object that
is changing lanes or turning left/right
• When passing a detectable object
which is stopped to make a left/right turn
• When a detectable object stops imme-
diately before entering the path of the vehicle• When passing through a location with
a structure above the road (traffic sign, billboard, etc.)
• When approaching an electric toll gate barrier, parking lot barrier, or other barrier that opens and closes
• When turning left/right and an oncom- ing vehicle or pedestrian crosses in front of the vehicle
• When attempting to turn left/right in front of an oncoming vehicle or pedes-trian
• When turning left/right and an oncom- ing vehicle or pedestrian stops imme-diately before entering the path of the
vehicle • When turning left/right and an oncom-ing vehicle turns left/right in front of
the vehicle

■Situations in which the system may
not operate properly
●In certain situations, such as the fol-
lowing, a detectable object may not be detected by the front sensors, and the system may not operate properly:
• When a detectable object is approaching your vehicle• When your vehicle or a detectable
object is wandering • When a detectable object makes an abrupt maneuver (such as sudden
swerving, acceleration or decelera- tion)• When suddenly approaching a detect-
able object • When the detectable object is near a wall, fence, guardrail, manhole cover,
steel plate on the road surface, or another vehicle• When there is a structure above a
detectable object • When part of a detectable object is hidden by another object (large lug-
gage, umbrella, guardrail, etc.) • When multiple detectable objects are overlapping
• When a bright light, such as the sun, is reflecting off of a detectable object• When a detectable object is white and
looks extremely bright • When the color or brightness of a detectable object causes it to blend in
with its surroundings • When a detectable object cuts in front of or suddenly emerges in front of
your vehicle • When approaching a vehicle which is diagonal
• If a vehicle ahead is a child sized bicy- cle, is carrying a large load, is carrying an extra passenger, or has an unusual
shape (bicycles equipped with a child seat, tandem bicycles, etc.)• If a pedestrian or bicycle is shorter
than approximately 1 m (3.2 ft.) or taller than approximately 2 m (6.5 ft.).• When the silhouette of a pedestrian or
bicycle is unclear (such as when they are wearing a raincoat, long skirt, etc.)• When a pedestrian or bicycle is bend-
ing forward or squatting
• When a pedestrian or bicycle is mov- ing at high speed• When a pedestrian is pushing a
stroller, wheelchair, bicycle or other vehicle• When a detectable object blends in
with the surrounding area, such as when it is dim (at dawn or dusk) or dark (at night or in a tunnel)
• When the vehicle has not been driven for a certain amount of time after the EV system was started
• While turning left/right or a few sec- onds after turning left/right• While driving around a curve and a
few seconds after driving around a curve• When turning left/right and an oncom-
ing vehicle is driving in a lane 3 or more lanes from the vehicle• When turning left/right and the direc-
tion of the vehicle differs greatly from the direction traffic flows in the oncoming lane
• When turning left/right and approach- ing a pedestrian which was traveling
in the same direction as the vehicle and continues straight

or an obstruction exists in the evasion direction• When there is an oncoming vehicle
 The pre-collision system can be
enabled/disabled through a cus-
tomize setting. ( P.568)
The system is enabled each time the
power switch is turned to ON.
 When the system is disabled, the
PCS warning light will illuminate
and a message will be displayed
on the multi-information display.
“Pre-Collision System OFF”
 The pre-collision setting can be
changed on the customize set-
tings. ( P.568)
 When the pre-collision warning
timing is changed, the emer-
gency steering assist (excluding
the active steering function) tim-
ing will also be changed. When
“Later” is selected, the emer-
gency steering assist (excluding
the active steering function) will
not operate in most cases.
 Vehicles with a driver monitor
camera: When the system deter-
mines that the driver is not facing
forward, the pre-collision warning
and emergency steering assist
will operate at the “Earlier” tim-
ing, regardless of the user set-
ting.
 When the dynamic radar cruise
control is operating, the pre-colli-
sion warning will operate at the
“Earlier” timing, regardless of the
user setting.
