■Intersection collision avoid-
ance support (left/right
turn)
In situations such as the follow-
ing, if the system determines
that the possibility of a collision
is high, the pre-collision warning
and pre-collision braking will
operate.
Depending on the intersection,
assistance may not operate cor-
rectly.
 When turning left/right at an
intersection and crossing the
path of an oncoming vehicle
 When turning left/right and an
oncoming pedestrian or bicy-
cle is detected■Intersection collision avoid-
ance support (crossing
vehicles)
At an intersection, etc., if the
system determines that the pos-
sibility of a collision with an
approaching vehicle or motorcy-
cle is high, the pre-collision
warning and pre-collision brak-
ing will operate.
Depending on the intersection,
assistance may not operate cor-
rectly.
■Acceleration Suppression
at Low Speed
When driving at a low speed, if
the accelerator pedal is strongly
depressed and the system
determines that there is a possi-
bility of a collision, engine output
will be restrained or the brakes
will be applied weakly to restrict

acceleration. During operation,
a buzzer will sound and a warn-
ing indicator and message will
be displayed on the multi-infor-
mation display.
WARNING
■Pre-collision braking
●When the pre-collision braking
function is operating, a large
amount of braking force will be
applied.
●The pre-collision braking func-
tion is not designed to hold the
vehicle stopped. If the vehicle is
stopped by pre-collision brake
control, the driver should oper-
ate the brakes immediately as
necessary.
●The pre-collision braking func-
tion 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-collision braking function
from operating.
●If the brake pedal is being
depressed, the system may
determine that the driver is tak-
ing evasive 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 sys-
tem determines that lane depar-
ture prevention control has
completed.
●Depending on operations per-
formed by the driver, emer-
gency 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 signal lever is operated, the
system may determine that the
driver is taking evasive action
and the emergency steering
assist may n ot operate.
• While the emergency steering assist is operating, if the accel-
erator pedal is depressed
strongly, the steering wheel is
turned heavily, or the brake
pedal is depressed, the system
may determine that the driver is
taking evasive action and emer-
gency steering assist operation
may be canceled.
• While the emergency steering assist is operating, if the steer-
ing wheel is held or turned in the
opposite direction of system
operation, emergency steering
assist operation will be can-
celed.

■Operating conditions of each function of the pre-collision system
The pre-collision syst em is enabled and the system determines t hat the pos-
sibility of a frontal c ollision with a detected object is high.
However, the system will not operate in the follo wing situations:
●When the vehicle has not been driven a certain amount after a t erminal of
the battery has been disc onnected and reconnected
●When the shift lever is in R
●When the VSC OFF indicator is illuminated (only the pre-collision warning
function will be operational)
The following are the operational speeds and cancelation condit ions of each
function:
●Pre-collision warning
While the pre-collision warning is operating, if the steering w heel is operated
heavily or suddenly, the pre-co llision warning may be cancelled.
●Pre-collision brake assist

the turn signal lig hts are flashing.
While the Acceleration Suppression at Low Speed function is ope rating, if
any of the following are performed, the low speed sudden acceleration sup-
pression function oper ation will be cancelled:
• The accelerator pedal is released.
• The steering wheel is ope rated heavily or suddenly
■Detection of detectable objects
Objects are detected based on their
size, shape, and movement.
Depending on the ambient bright-
ness, movement, pos ture and direc-
tion of a detectable object, it may
not be detected and the system may
not operate properly.
The system detects shapes, such as
the following, as de tectable objects.
■Situations in which the system
may operate even though the
possibility of a collision is not
high
●In certain situations, such as the
following, the sys tem may deter-
mine that the possibility of a colli-
sion is high and operate:
• When passing a detectable object
• When changing lanes while over-
taking a detectable object • When suddenly approaching a
detectable object
• When approaching a detectable
object or other ob ject on the road-
side, such as guardrails, utility
poles, trees, walls, etc.
• When there is a d etectable 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 mistaken for a detectable
object
• When passing a detectable object
that is changing lanes or turning
left/right

■Situations in which the system
may not operate properly
●In certain situations, such as the
following, a detectable object may
not be detected by the front sen-
sors, 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 sud-
den swerving, acceleration or
deceleration)
• When suddenly approaching a detectable object
• When the detectable object is
near a wall, fence, guardrail, man-
hole 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
luggage, umbrella, guardrail, etc.)
• When multiple det ectable objects
are overlapping
• When a bright light, such as the sun, is reflecting off of a detect-
able 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
