Driving
The system can detect the fol-
lowing as detectable objects.
(Detectable objects differ
depending on the function.)
Vehicles
 Bicycles
*
Pedestrians
 Motorcycles
*
*: Detected as a detectable object
only when being ridden.
■Pre-collision warning
When the system determines
that the possibility of a collision
is high, a buzzer will sound and
an icon and warning message
will be displayed on the
multi-information display to urge
the driver to take evasive action.
If the detectable object is a vehi-
cle, moderate braking will be
performed with the warning.
If the system determines that
the accelerator pedal is strongly
depressed, the following icon
and message will be displayed
on the multi-information display.
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Pay
careful attention to the sur-
rounding conditions in order to
ensure safe driving.
Never use the pre-collision sys-
tem in place of normal braking
operations. This system cannot
help avoid or reduce the impact
of a collision in every situation.
Over-reliance on this system to
drive the vehicle safely may
lead to an accident resulting in
death or serious injury.
●Although the pr e-collision sys-
tem is designed to help avoid or
help reduce the im pact of a col-
lision, its effectiveness may
change according to various
conditions. Therefore, it may not
always be able to achieve the
same level of performance.
Read the followi ng items care-
fully. Do not overl y rely on this
system and always drive care-
fully.

System functions

1924-5. Using the driving support systems
■Pre-collision brake assist
If the system determines that
the possibility of a collision is
high and the brake operation by
the driver is insufficient, the
braking power will be increased.
■Pre-collision brake control
If the system determines that
the possibility of a collision is
extremely 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,
assistance will be provided to
help enhance vehicle stability
and prevent lane departure.
During assistance, in addition to
the pre-collision warning, the fol-
lowing icon will be displayed on
the multi-information 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
steering wheel
During assistance, the pre-colli-
sion warning will operate and a
message will be displayed to
warn the driver.
■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

Driving
■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 desig
ned to hold the
vehicle stopped. If the vehicle is
stopped by pre-collision brake
control, the dri ver 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 t he driver is tak-
ing evasive action and possibly
delay the operation timing of the
pre-collision brake control.

1944-5. Using the driving support systems
WARNING
■Acceleration Suppression at
Low Speed
If the steering wheel is being
turned, the syste m 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 not operate.
• While the emergency steering assist is operating, if the accel-
erator pedal is depressed
strongly, the st eering 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
