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 con-
trol with full-speed range
( P.271) 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 cam-
era. 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

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehi-
cle-to-vehicle following distance, and operates to maintain a s uitable
following distance from the vehicle ahead. The desired vehi-
cle-to-vehicle distance can also be set by operating the vehi-
cle-to-vehicle distance switch.
When driving on downhill slopes, t he vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected runni ng ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you st ops, your vehicle will also stop (vehicle is
stopped by system control). Afte r the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not pe rformed, system
control continues to keep your vehicle stopped.

tions.
Failing to do so may result in the
vehicle being unable to be driven
safely and possibly cause an acci-
dent.
●Do not use the sensor at
speeds in excess of 6 mph (10
km/h).
●The sensors’ detection areas
and reaction times are limited.
When moving forward or revers-
ing, check the areas surround-
ing the vehicle (especially the
sides of the vehicle) for safety,
and drive slowly, using the
brake to control the vehicle’s
speed.
●Do not install accessories within
the sensors’ d etection areas.
●The area directly under the
bumpers is not detected.
Thin posts or objects lower than
the sensor may not be detected
when approached, even if they
have been detected once.
■When to disable the function
In the following situations, disable
the function as it may operate
even though there is no possibility
of a collision.
●The vehicle is equipped with a
fender pole, wireless antenna or
fog lights.
●The front or rear bumper or a
sensor receives a strong
impact.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.)
is installed.
