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.

Owners Manual_Europe_M42D76_en
5-4. Using the driving support systems
When driving on a road with
clear lane lines with the dynamic
radar cruise control operating,
lane lines and preceding and
surrounding vehicles are
detected using the front camera
and radar sensor, and the steer-
ing wheel is operated to maintain
the vehicle’s lane position.
Use the this function only on highways
and expressways.
If the dynamic radar cruise control is
not operating, the function will not oper-
ate.
In situations where the lane lines are
difficult to see or are not visible, such as
when in a traffic jam, support will be
provided using the path of preceding
and surrounding vehicles.
If the system determines that the steer-
ing wheel has not been operated for a
certain amount of time or the steering
wheel is not being firmly gripped, the
driver will be alerted via a display and
this function will be temporarily can-
celed.
If the steering wheel is firmly gripped,
the function will begin operating again.
 When the function is operating, if
the vehicle is likely to depart from
its lane, the driver will be alerted
via a display and buzzer.
When the buzzer sounds, check the
area around the vehicle and carefully
operate the steering wheel to move the
vehicle back to the center of the lane.

■Operating conditions of function
This function is operable when all of the following conditions are met:
●The LTA system detects lane lines or
the path of preceding or surrounding
vehicles (except when the preceding vehicle is small, such as a motorcy-cle).
●The dynamic radar cruise control is operating.
●The lane width is approximately 3 to 4 m (10 to 13 ft.).
●The turn signal lever is not being oper-ated.
●The vehicle is not being driven around a sharp curve.
●The vehicle is not accelerating or decelerating more than a certain
amount.
●The steering wheel is not being turned
with a large force.
●The hands off steering wheel warning
( P.296) is not operating.
●The vehicle is being driven in the
center of a lane.
■Temporary cancelation of functions
●When the operating conditions are no
longer met, a function may be tempo- rarily canceled. However, when the operation conditions are met again,
operation of the function will automati- cally be restored. ( P.295)
●If the operating conditions of a func- tion are no longer met while the func-tion is operating, a buzzer may sound
to indicate that the function has been temporarily canceled.
●The steering assist operation of the function can be overridden by the steering wheel operation of the driver.
■Lane departure warning function
when the LTA is operating
●Even if the LDA warning method is
changed to vibration of the steering wheel, if the vehicle deviates from the lane while the LTA is operating, the
warning buzzer will sound to alert the driver.
●If steering wheel operation equivalent to that necessary for a lane change is
WARNING
■Before using the LTA system
●Do not overly rely on the LTA sys-tem. The LTA system is not a sys-
tem which provides automated assistance in driving and it is not a system which reduces the amount
of attention necessary for safe driv- ing. The driver is solely responsible for paying attention to their sur-
roundings and operating the steer- ing wheel as necessary to ensure safety. Also, the driver is responsi-
ble for taking adequate breaks when fatigued, such as when driv-ing for a long time.
●Failure to perform appropriate driv-ing operations and pay careful
attention may lead to an accident.
●When not using the LTA system,
turn it off using the LTA switch.
