Toyota RAV4 (XA50) 2019-2024 Owners Manual: 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 current
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
system will operate the
steering wheel to maintain
the vehicle's lane position.
The LTA system recognizes
white (yellow) lane lines or a
course* using the front camera.
Additionally, 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
WARNING
â– Before using LTA system
- Do not rely solely upon the LTA
system. The LTA system does
not automatically drive the vehicle
or reduce 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 paying careful attention
to the surrounding conditions
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 careful
attention may lead to an
accident, resulting in death or
serious injury.
â– 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.

freezing, etc.

may not operate properly
In the following situations, the
