◆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.

tion to the operation conditions for the lane departure alert function.

play is set to “On”. ( →P. 85)
• 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. 85)
• 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. 220)

■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. 217)
■ 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

2504-5. Using the driving support systems
◆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
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
◆BSM (Blind Spot Monitor) (if equipped)
→ P. 2 3 9
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.
Page 252 of 492

2524-5. Using the driving support systems
■Turning off both TRAC/VSC systems
To turn the TRAC/VSC systems off, press and hold the switch for more than 3
seconds while the vehicle is stopped.
The VSC OFF and “TRAC OFF” and a message will be shown on the mult\
i-
information display
*.
Press the switch again to turn the systems back on.
*: On vehicles with pre-collision system, pre-collision brake assist and pre- collision braking will also be disabled. The pre-collision system warning
light will come on and the message will be shown on the multi-information
display. ( →P. 210)
■ When the message is displayed on th e multi-information display show-
ing that TRAC has been disabled even if the TRAC/VSC OFF switch has
not been pressed
TRAC cannot be operated. Contact your Toyota dealer.
■ Sounds and vibrations caused by the ABS, brake assist, VSC and TRAC
systems
● A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● When the engine switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the engine of\
f. The
EPS system should return to normal within 10 minutes.
