◆Vehicle sway warning
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. LDA is not a system which auto-
matically drives the vehicle or reduces 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 always paying careful attention to the sur-
rounding conditions and operate the steering wheel to correct the path of
the vehicle. Also, make sure to take adequate breaks when fatigued, such
as from driving for a long period of time.Failure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident, resulting
in death or serious injury.
■ To avoid operating LDA by mistake
When not using the LDA system, use the LDA switch to turn the system off.

steering control function is operat-
ing.
Flashing in amber:
Lane departure alert function is
operating.

■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. 230)
● 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 “Settings” of the multi-information dis-
play is set to “On”. ( P. 96)
• 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.
• When the VSC or TRAC system is turned off by pressing the VSC OFF switch.
● Vehicle sway warning
This function operates when all of the following conditions are met.
• Setting for “ Alert” in “Settings” of the multi-information display is set to
“On”. ( P. 96)
• Vehicle speed is approximately 32 mph (50 km/h) or more.
• Width of traffic lane is approximately 9.8 ft. (3 m) or more.
• No system malfunctions are detected. ( P. 230)

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. 227)
■ Steering control function
Depending on the vehicle speed, lane departure situation, road conditions,
etc., the operation of the functions may not be recognized or the functions
may not operate.
■ 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 their hands from
the steering wheel while the steering control function is operating, a warning
message is displayed on the multi-information display and the buzzer
sounds.
■ 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.

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 the road curves or when the
lanes are narrow
● When steering wheel operation or your
position in the lane is unstable

◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corre-
sponding to the brake operation
◆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 st ability when swerving on slippery
road surfaces by controllin g steering performance.
◆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
Prevents the vehicle from rolling backward when starting on an
incline or slippery slope
Driving assist systems
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
◆BSM (Blind Spot Monitor) (if equipped)

The slip indicator light will flash
while the TRAC/VSC/ABS sys-
tems are operating.
If the vehicle gets stuck in mud, dirt or snow, the TRAC systems may
reduce power from the hybrid syst em to the wheels. Pressing the
switch 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 the
switch.
The “TRAC OFF” and a message
will be shown on the multi-informa-
tion display.
Press the switch again to turn the
system back on.
