2424-5. Using the driving support systems
Owners Manual_USA_M0C031_en
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.
