LDA (Lane Depar ture Alert With Yaw Assist
Function)
When driving on a road with clear white (yellow) lane lines, this func-
tion alerts the driver when the vehicle might depart from its lane or
course* and provides assistance by applying a brake force to keep
the vehicle in its lane or course*.
The LDA system recognizes white
(yellow) lane lines or a course*
using the front camera. Addition-
ally, it detects preceding vehicles
using the front camera and radar.
*: Boundary between asphalt and the
side of the road, such as grass,
soil, or a curb
: If equipped
Summary of functions
WARNING
Q Before using LDA system
O 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.
O Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
O When not using the LDA system, use the LDA switch to turn the system
off.

WARNING
QConditions in which functions may not operate properly
In the following situations, the functions may not operate properly and the
vehicle may depart from its lane. Drive safely by always paying careful
attention to your surroundings and operate the steering wheel to correct the
path of the vehicle without relying solely on the functions.
O Vehicle is being driven around a sharp curve.
O There are shadows on the road that run parallel with, or cover, the white
(yellow) lines.
O The vehicle is driven in an area without white (yellow) lines, such as in
front of a tollgate or checkpoint, or at an intersection, etc.
O Objects or patterns that could be mis-
taken for white (yellow) lines are pres-
ent on the side of the road (guardrails,
reflective poles, etc.).
O Vehicle is driven where the road
diverges, merges, etc.
O Repair marks of asphalt, white (yellow)
lines, etc. are present due to road
repair.

• LDA is turned on.
• Vehicle speed is approximately 50 km/h (32 mph) or more.
• System recognizes white (yellow) lane lines or a course*. (When a
white [yellow] line or course* is recognized on only one side, the system
will operate only for the recognized side.)
• Width of traffic lane is approximately 3 m (9.8 ft.) or more.
• Turn signal lever is not operated.
• Vehicle is not being driven around a sharp curve.
• No system malfunctions are detected. ( P. 294)
*: Boundary between asphalt and the side of the road, such as grass, soil,
or a curb
O Yaw assist function
This function operates when all of the following conditions are met in addi-
tion to the operation conditions fo r the lane departure alert function.
• Setting for “Yaw assist” in of the multi-information display is set
to “On” ( P. 135)
• 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, TRC/A-TRC and PCS are not operating.
• TRC/A-TRC or VSC is not turned off.

Q Temporary cancelation 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. 292)
Q Yaw assist function
O Depending on the vehicle speed, lane departure situation, road conditions,
etc., the driver may not feel the func tion is operating or the function may not
operate at all.
O The yaw assist of the function is overridden by the driver’s steering wheel
operation.
O Do not attempt to test the operation of the yaw assist function.
O A sound may be heard from the engine compartment when the brake pedal
is depressed, when the yaw assist function is operating. This sound does
not indicate that a malfunction is occurred in the LDA system.
Q Lane departure alert function
O The warning buzzer may be difficult to hear due to external noise, audio
playback, etc.
O If the edge of the course* is not clear or straight, the lane departure alert
function may not operate.
O Do not attempt to test the operation of the lane departure alert function.
*: Boundary between asphalt and the side of the road, such as grass, soil,
or a curb
Q Vehicle sway warning function
Depending on the vehicle and road conditions, the warning may not operate.
When the system determines that the
vehicle is swaying while the vehicle sway
warning function is operating, a buzzer
sounds and a warning message urging
the driver to rest and the symbol shown in
the illustration are simultaneously dis-
played on the multi-information display.

Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 80 km/h (50 mph) or more, the vehicle will
accelerate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus right side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side from where the
vehicle is normally driven, the vehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking lane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane
is to the right but then drives to a region where the overtaking lane is to the
left, the vehicle may accelerate when the right turn signal is activated).
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.
