◆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.

2644-5. Using the driving support systems
Press the LDA switch to turn the
LDA system on.
The LDA indicator illuminates and
a message is displayed on the
multi-information display.
Press the LDA switch again to turn
the LDA system off.
When the LDA system is turned on
or off, operation of the LDA system
continues in the same condition
the next time the hybrid system is
started.

■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. 269)
● 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. 105, 119)
• 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.
● 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. 105, 119)

■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. 266)
■ 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.

2704-5. Using the driving support systems
In vehicle-to-vehicle distance co ntrol mode, the vehicle automatically
accelerates, decelerates and stops to match the speed changes of the
preceding vehicle even if the acce lerator pedal is not depressed. In
constant speed control mode, t he vehicle runs at a fixed speed.
Use the dynamic radar cruise control with full-speed range on free-
ways and highways.

Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
Press the cruise control main
switch to activate the cruise
control.
Radar cruise control indicator will
come on and a message will be
displayed on the multi-information
display.
Press the switch again to deacti-
vate the cruise control.
If the cruise control main switch is pressed and held for 1.5 seconds or
more, the system turns on in constant speed control mode. ( →P. 279)
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 30 mph
[50 km/h]) and press the “- SET”
switch to set the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the switch is released becomes the
set speed.
If the switch is operated while the vehicle speed is below approximately 30
mph (50 km/h) and a preceding vehicle is present, the set speed will be
adjusted to approximately 30 mph (50 km/h).
