Toyota Corolla Cross: LTA (Lane Tracing Assist)
LTA functions
- When driving on a road with
clear lane lines with the
dynamic radar cruise control
operating, lane lines and preceding
and surrounding vehicles
are detected using the
front camera and radar sensor,
and the steering wheel is
operated to maintain the vehicle's
lane position.
Use this function only on highways
and expressways.
If the dynamic radar cruise control
is not operating, the function will not
operate.
In situations where the lane lines
are difficult to see or are not visible,
such as when in a traffic jam, support
will be provided using the path
of preceding and surrounding vehicles.
If the system determines that the
steering wheel has not been operated
for a certain amount of time or
the steering wheel is not being
firmly gripped, the driver will be
alerted and this function will be
temporarily canceled.
If the steering wheel is firmly
gripped, the function will begin
operating again.
- When the function is operating,
if the vehicle is likely to
depart from its lane, the driver
will be alerted via a display
and buzzer.
When the buzzer sounds, check
the area around the vehicle and
carefully operate the steering wheel
to move the vehicle back to the
center of the lane.
WARNING
■Before using the LTA system
- Do not overly rely on the LTA
system. The LTA system is not a
system which provides automated
assistance in driving and
it is not a system which reduces
the amount of attention necessary
for safe driving. The driver
is solely responsible for paying
attention to their surroundings
and operating the steering
wheel as necessary to ensure
safety. Also, the driver is
responsible for taking adequate
breaks when fatigued, such as
when driving for a long time.
- Failure to perform appropriate
driving operations and pay careful
attention may lead to an
accident.
- When not using the LTA system,
turn it off using the LTA switch.
■Operating conditions of function
This function is operable when all of the following conditions are met:
- The LTA system detects lane lines
or the path of preceding or surrounding
vehicles.
- The dynamic radar cruise control
is operating.
- The lane width is approximately
10 to 13 ft. (3 to 4 m).
- The turn signal lever is not being
operated.
- The vehicle is not being driven
around a sharp curve.
- The vehicle is not accelerating or
decelerating more than a certain
amount.
- The steering wheel is not being
turned with a large force.
- The hands off steering wheel
warning is not operating.
- The vehicle is being driven in the
center of a lane.
■Temporary cancelation of functions
- When the operating conditions are
no longer met, a function may be
temporarily canceled. However,
when the operation conditions are
met again, operation of the function
will automatically be restored.
- If the operating conditions of a
function are no longer met while
the function is operating, a buzzer
may sound to indicate that the
function has been temporarily
canceled.
- The steering assist operation of
the function can be overridden by
the steering wheel operation of
the driver.
■Lane departure warning function
when the LTA is operating
- Even if the LDA warning method is
changed to vibration of the steering
wheel, if the vehicle deviates
from the lane while the LTA is
operating, the warning buzzer will sound to alert the driver.
- If steering wheel operation equivalent
to that necessary for a lane
change is detected, the system
will determine the vehicle is not
deviating from the lane and the
warning will not operate.
■Hands off steering wheel warning
operation
- When the system determines the
driver is not holding the steering
wheel, a message urging the
driver to grip the steering wheel
and the icon shown in the illustration
will be displayed on the
multi-information display to warn
the driver. If the system detects
that the steering wheel is held, the
warning will be canceled. When
using the system, make sure to
grip the steering wheel firmly,
regardless of whether the warning
is operating or not.
- If no operations are detected for a
certain amount of time, the warning
will operate and the function
will be temporarily canceled. This
warning may also operate if the
driver only operates steering
wheel a small amount continuously.
■Situations in which the hands
off steering wheel warning may
not operate properly
- Depending on the condition of the
vehicle, handle control condition
and road surface, the warning
function may not operate.
Enabling/disabling the
system
The LTA will change between
ON/OFF each time the LTA
switch is pressed.
When the LTA is ON, the LTA indicator
will illuminate.
WARNING
■Situations in which the functions
may not operate properly
In the following situations, the
functions may not operate properly
and the vehicle may depart
from its lane. Do not overly rely on
these functions. The driver is
solely responsible for paying
attention to their surroundings
and operating the steering wheel
as necessary to ensure safety.
- When a preceding or surrounding
vehicle changes lanes (Your
vehicle may follow the preceding
or surrounding vehicle and
also change lanes)
- When a preceding or surrounding
vehicle is swaying (Your
vehicle may sway accordingly
and depart from the lane)
- When a preceding or surrounding
vehicle departs from a lane
(Your vehicle may follow the
preceding or surrounding vehicle
and also depart from the
lane)
- When a preceding or surrounding
vehicle is being driven
extremely close to the left/right
lane line (Your vehicle may follow
the preceding or surrounding
vehicle accordingly and
depart from the lane)
- When there are moving objects
or structures in the surrounding
area (Depending on the position
of the moving object or structure
relative to your vehicle, your
vehicle may sway)
- When the vehicle is struck by a
crosswind or the turbulence of
other nearby vehicles
- Situations in which the sensors
may not operate properly
- Situations in which the lane may
not be detected
- When it is necessary to disable
the system
