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.
●The lane centering function will
be disabled automatically when
LTA detects a trailer connection.
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.
●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.

WARNING
●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.
●White (yellow) lines are difficult
to see due to rain, snow, fog,
dust, etc.
●Vehicle is driven in a temporary
lane or restricted lane due to
construction work.
●Vehicle is driven in a construc-
tion zone.
●A spare tire, tire chains, etc.,
are equipped.
●When the tires have been
excessively worn, or when the
tire inflation pressure is low.
●When your vehicles is towing a
trailer or another vehicle, except
when the following condition is
met.
• When the other vehicle is a trailer properly attached and
connected to Toyota’s official
TBC ECU. ( P.181)
●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
your Toyota dealer.
●Do not install or place anything
on the hood or grille. Also, do
not install a gr ille guard (bull
bars, kangaroo bar, etc.).
●If your windshield needs
repairs, contact your Toyota
dealer.
■Conditions in which functions
may not operate properly
In the following situations, the
functions may not operate prop-
erly 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.
●When the follow-up cruising dis-
play is displayed ( P.248) and
the preceding vehicle changes
lanes. (Your vehicle may follow
the preceding vehicle and also
change lanes.)
●When the follow-up cruising dis-
play is displayed ( P.248) and
the preceding vehicle is sway-
ing. (Your vehicle may sway
accordingly and depart from the
lane.)

■Lane departure alert func-
tion
When the system determines
that the vehicle might depart
from its lane
*, a warning is dis-
played on the multi-information
display, and either a warning
buzzer will sound or the steering
wheel will vibrate to alert the
driver.
When the warning buzzer sounds
or the steering wheel vibrates,
check the area around your vehicle
and carefully operate the steering

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehicle-
to-vehicle following distance, and operates to maintain a suitable fol-
lowing distance from the vehicle ahead. The desired vehicle-to- vehi-
cle distance can also be set by operating the vehicle-to-vehicle
distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distanc e may
become shorter.
WARNING
●When weather conditions are
bad enough that they may pre-
vent the sensors from detecting
correctly (fog, snow, sand-
storm, heavy rain, etc.)
●When there is rain, snow, etc.,
on the front surface of the radar
or front camera
●In traffic conditions that require
frequent repeated acceleration
and deceleration
●When your vehicles is towing a
trailer or another vehicle, except
when the following condition is
met.
