When driving on highways and freeways with white (yellow) lines, this
function alerts the driver when the vehicle might depart from its lane
and provides assistance by operatin g the steering wheel to keep the
vehicle in its lane.
The LDA system recognizes visi-
ble white (yellow) lines with the
camera sensor on the upper por-
tion of the front windshield.

◆Lane departure alert function
When the system determines
that the vehicle might depart
from its lane, a warning is dis-
played on the multi-information
display and the warning buzzer
sounds to alert the driver.
When the warning buzzer
sounds, check the surrounding
road situation and carefully
operate the steering wheel to
move the vehicle back to the
center of the lane.
◆Steering control function
When the system determines
that the vehicle might depart
from its lane, the system pro-
vides assistance as necessary
by operating the steering wheel
in small amounts for a short
period of time to keep the vehi-
cle in its lane.
If the system detects that the
steering wheel has not been
operated for a fixed amount of
time or the steering wheel is not
being firmly gripped, a warning
is displayed on the multi-infor-
mation display and the warning
buzzer sounds.

◆Vehicle sway warning function
When the vehicle is swaying or
appears as if it may depart from
its lane multiple times, the
warning buzzer sounds and a
message is displayed on the
multi-information display to alert
the driver.
WARNING
■Before using LDA system
Do not rely solely upon the LDA system. The LDA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigued, such as
from driving for a long period of time.
Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
■ To avoid operating LDA system by mistake
When not using the LDA system, use the LDA switch to turn the system off.

■Operation conditions of each function
●Lane departure alert function
This function operates when all of the following conditions are met.
• LDA is turned on.
• Vehicle speed is approximately 32 mph (50 km/h) or more.
• System recognizes white (yellow) lines.
• Width of traffic lane is approximately 9.8 ft. (3 m) or more.
• Turn signal lever is not operated.
• Vehicle is driven on a straight road or around a gentle curve with a radius
of more than approximately 492 ft. (150 m).
• No system malfunctions are detected. ( →P. 262)
● Steering control function
This function operates when all of the following conditions are met in addi-
tion to the operation conditions for the lane departure alert function.
• Setting for “Steering Assist” in (4.2-inch display) or (7-inch dis-
play) of the multi-information display is set to “On”. ( →P. 92, 104)
• Vehicle is not accelerated or decelerated by a fixed amount or more.
• Steering wheel is not operated with a steering force level suitable for changing lanes.
• ABS, VSC, TRAC and PCS are not operating.
• TRAC or VSC is not turned off.
• Hands off steering wheel alert is not displayed. ( →P. 260)
● Vehicle sway warning
This function operates when all of the following conditions are met.
• Setting for “Sway Warning” in (4.2-inch display) or (7-inch display)
of the multi-information display is set to “On”. ( →P. 92, 104)

Temporary cancellation of functions
When operation conditions are no longer met, a function may be temporarily\
canceled. However, when the operation conditions are met again, operation
of the function is automatically restored. (→P. 259)
■ Steering control function
Depending on the vehicle speed, lane departure situation, road conditions,
etc., the driver may not feel the function is operating or the function may not
operate at all.
■ Lane departure alert function
The warning buzzer may be difficult to hear due to external noise, audio play-
back, etc.
■ Hands off steering wheel alert
When the system determines that the driver has removed the hands from the
steering wheel while the steering control function is operating, a warning
message is displayed on the multi-information display.
If the driver continues to keep the hands off of the steering wheel, a buzzer
sounds, a warning message is displayed. This alert also operates in the same
way when the driver continuously operates the steering wheel only a small
amount. However, depending on the road conditions, etc., the function may
not cancel.
■ White (yellow) lines are only on one side of road
The LDA system will not operate for the side on which white (yellow) lines
could not be recognized.

Motorcycles traveling in the same lane
● When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor
■ Conditions under which the vehicle -to-vehicle distance control mode
may not function correctly
In the case of the following conditions, operate the brake pedal (or accelera-
tor pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system
may not operate properly.
● When the vehicle ahead of you decelerates suddenly
●
When your vehicle is pointing upwards
(caused by a heavy load in the luggage
compartment, etc.)
● Preceding vehicle has an extremely
high ground clearance
●When the road curves or when the
lanes are narrow
● When steering wheel operation or your
position in the lane is unstable

◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces.
◆Enhanced VSC (Enhanced Ve hicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery
road surfaces by controllin g steering performance.
◆Secondary Collision Brake (if equipped)
When the airbag sensor detects a collision, the brakes and brake
lights are automatically controlled to reduce the vehicle speed and
that helps reduce the possibility of further damage due to a second-
ary collision
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆Hill-start assist control
Helps to reduce the backward move ment of the vehicle when start-
ing on an uphill
Driving assist systems
To keep driving safety and perf ormance, the following systems
operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too he avily when operating the vehi-
cle.

The slip indicator light will flash
while the TRAC/VSC systems are
operating.
If the vehicle gets stuck in mud, di rt or snow, the TRAC system may
reduce power from the engine to the wheels. Pressing to turn
the system off may make it easier for you to rock the vehicle in order
to free it.
To turn the TRAC system off,
quickly press and release .
“Traction Control Turned Off” will
be shown on the multi-information
display.
Press again to turn the sys-
tem back on.
