Driving
While driving on a road with
clear white (yellow) lane lines,
the LTA system warns the driver
if the vehicle may deviate from
the current lane
*, and also can
slightly operate the steering
wheel to help avoid deviation
from the lane. Also, while the
dynamic radar cruise control
with full-speed range is operat-
ing, this system will operate the
steering wheel to maintain the
vehicle’s lane position.
The LTA system recognizes
white (yellow) lane lines
* using
the front camera. Additionally, it
detects preceding vehicles
using the front camera and
radar.
*: May recognize the boundaries between the asphalt and the side
of the road, such as grass, soil, or
the curb, to be road lanes
LTA (Lane Tracing
Assist)
Summary of functions
WARNING
■Before using LTA system
●Do not rely solely upon the LTA
system. The LTA system does
not automatically drive the vehi-
cle or reduce the amount of
attention that m ust be paid to
the area in front of the vehicle.
The driver must always assume
full responsibilit y for driving
safely by paying careful atten-
tion to the surrounding condi-
tions 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 care-
ful attention may lead to an
accident, resulting in death or
serious injury.
●When connecting a trailer which
can be connected with Toyota’s
official TBC ECU, the lane cen-
tering function will be disabled
automatically when LTA detects
a trailer connection.
When other trailer is connected,
turn off the lane centering func-
tion if a trailer is connected and
it is not automatically disabled.
After trailer disconnect and
power switch is turned off, lance
centering function can be turned
on.

WARNING
●This vehicle has Automatic
Trailer Detection feature that
can detect certain trailers under
certain conditions. After trailer is
detected, lane centering func-
tion will be disabled. In certain
conditions, there is a possibility
of falsely detecting trailer when
there is no actual trailer. In that
case, lane centering function
will be disabled. To activate lane
centering function, turn power
switch to off and then turn it on
again.
●Following scenes has possibility
of false detection of trailer:
Crowded environments such as
parking lots or camping
grounds, closely following vehi-
cles such traffic jam, drive
through, parallel parking, etc.
●Do not use the lane centering
system and steering assist func-
tion when the vehicle is lifted
unless using a Toyota official lift
up kit up to 4 in. (101 mm),
including tire height. Aftermar-
ket lift kits may degrade system
performance.
■Situations unsuitable for LTA
system
In the following situations, use the
LTA switch to turn the system off.
Failure to do so may lead to an
accident, resulting in death or
serious injury.
●Vehicle is driven on a road sur-
face which is slippery due to
rainy weather, fallen snow,
freezing, etc.
●Vehicle is driven on a snow-cov-
ered road.

met.
• When the other vehicle is a trailer properly attached and
connected to Toyota’s official
TBC ECU. ( P.198)
●When the vehicle is lifted up,
except in the following cases.
• When using a Toyota official lift kit up to 4 in. (101 mm), includ-
ing tire height. Aftermarket lift
kits may degrade system perfor-
mance.
■Preventing LTA system mal-
functions and operations per-
formed by mistake
●Do not modify the headlights or
place stickers, etc., on the sur-
face of the lights.
●Do not modify the suspension,
etc. If the suspension, etc.,
needs to be replaced, contact
