Toyota GR Corolla Manual page 167

the following conditions are met:
● The LTA system detects lane lines
or the path of preceding or sur-
rounding vehicles (except when
the preceding vehicle is small,
such as a motorcycle).
● 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 (P.167) is not operat-
ing.
● The vehicle is being driven in the
center of a lane.
■ Temporary cancelation of func-
tions
● 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 func-
tion will automatically be restored.
(P.166)
● 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 func-
tion when the LTA is operating
● Even if the LDA warning method is
changed to vibration of the steer-
ing wheel, if the vehicle deviates
4-5. Using the driving support systems
from the lane while the LTA is
operating, the warning buzzer will
sound to alert the driver.
● If steering wheel operation equiv-
alent 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 warn-
ing operation
In the following situations, a mes-
sage 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 warn-
ing will be canceled. When using the
system, make sure to grip the steer-
ing wheel firmly, regardless of
whether the warning is operating or
not.
● When the system determines the
driver is not holding the steering
wheel while the function is operat-
ing
If no operations are detected for a
certain amount of time, a buzzer will
sound, the warning will operate, and
the function will be temporarily can-
celed. This warning may also oper-
ate if the driver only operates
steering wheel a small amount con-
tinuously.
Depending on the condition of the
vehicle, handle control condition
and road surface, the warning func-
tion may not operate.
