Cancelation of functions
In the following situations, opera-
tion of the LCA may be canceled
with the display and buzzer:
●
When the operating conditions
(P.262) are no longer met
●
When the system can no longer
detect lane lines
●
When the turn signal lever is oper-
ated to the second position
(P.263)
●
When the turn signal lever is oper-
ated in the opposite direction of
the lane change
●
When the system detects opera-
tion of the steering wheel, brake
pedal or accelerator pedal by the
driver.
If the system detects that a vehicle
is quickly approaching in the lane
toward which the turn signal is oper-
ated a buzzer will sound and a mes-
sage will be displayed to alert the
driver. At the same time the steering
wheel may be slightly operated to
help keep the vehicle away from the
approaching vehicle.

Hands off steering wheel warn-
ing 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

tem detects that the steering wheel
is held, the warning will be can-
celed. When using the system,
make sure to grip the steering wheel
firmly, regardless of whether the
warning is operating or not.
