■ Situations in which the system may not operate properly
● In some situations such as the following, an object may not be detected by
the radar sensor and front camera, preventing the system from o perating
properly:
• When a detectable object is approaching your vehicle
• When your vehicle or a detectable object is wobbling
• If a detectable object makes an abrupt maneuver (such as sudde n swerv-
ing, acceleration or deceleration)
• When your vehicle approaches a detectable object rapidly
• When a detectable object is near a wall, fence, guardrail, man hole cover,
vehicle, steel plate on the road, etc.
• When a detectable object is under a structure
• When part of a detectable object is hidden by an object, such as large
baggage, an umbrella, or guardrail
• When there are many things which can reflect the radio waves o f the
radar in the vicinity (tunnels, truss bridges, gravel roads, sn ow covered
road that have tracks, etc.)
• When there is an effect on the radio waves to the radar that i s installed on
another vehicle
• When multiple detectable objects are close together
• If the sun or other light is shining directly on a detectable object
• When a detectable object is a shade of white and looks extreme ly bright
• When a detectable object appears to be nearly the same color o r bright-
ness as its surroundings
• If a detectable object cuts or suddenly emerges in front of yo ur vehicle
• When the front of your vehicle is hit by water, snow, dust, et c.
• When a very bright light ahead, such as the sun or the headlig hts of
oncoming traffic, shines dir ectly into the front camera
• When approaching the side or front of a vehicle ahead
• If a vehicle ahead is a motorcycle
• If a vehicle ahead is narrow, such as a personal mobility vehi cle
• If a preceding vehicle has a small rear end, such as an unload ed truck

LTA (Lane Tracing Assist)
While driving on a road with clear white (yellow) lane lines, the LTA
system warns the driver if the vehicle may deviate from the cur rent
lane or course*, and also can slightly operate the steering wheel to
help avoid deviation from the lane or course*. Also, while the dynamic
radar cruise control with full-speed range is operating, this s ystem will
operate the steering wheel to maintain the vehicle’s lane posit ion.
The LTA 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
■ Before using LTA system
● Do not rely solely upon the LTA system. The LTA system does not auto-
matically drive the vehicle or reduce the amount of attention t hat 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 t o the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigu ed, 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.

Depending on the vehicle and road conditions, the warning may n ot operate.
■ Warning message
If the following warning message is displayed on the multi-info rmation display
and the LTA indicator illuminates in orange, follow the appropr iate trouble-
shooting procedure. Also, if a different warning message is dis played, follow
the instructions displayed on the screen.
● “LTA Malfunction. Visit Your Dealer.”
The system may not be operating properly. Have the vehicle insp ected by
any authorized Toyota retailer or Toyota authorized repairer, o r any reliable
repairer.
● “LTA Unavailable”
The system is temporarily canceled due to a malfunction in a se nsor other
than the front camera. Turn the LTA system off, wait for a litt le while, and
then turn the LTA system back on.
● “LTA Unavailable at Current Speed.”
The function cannot be used as the vehicle speed exceeds the LT A opera-
tion range. Drive slower.
■ Customization
Function settings can be changed. (Customizable features: P. 788)
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

RSA (Road Sign Assist)
The RSA system recognizes spe-
cific road signs using the front
camera and/or navigation system
(when speed limit information is
available) to provide information
to the driver via the display.
If the system judges that the vehicle is being driven over the speed
limit, performing prohibited actions, etc., according to the re cognized
road signs, it notifies the driver through a visual notificatio n and notifi-
cation buzzer.
: If equipped
Summary of function
WARNING
■ Before using the RSA
Do not rely solely upon the RSA system. RSA is a system which s upports
the driver by providing information, but it is not a replacemen t for a driver’s
own vision and awareness. Drive safely by always paying careful attention
to the traffic rules.
