Indication on the multi-information displayWhile the LKA system is on, the lane line display and steering wheel dis-
play (in case of lane keeping assist function) are shown on the multi-infor-
mation display to inform that the LKA system is on. Steering wheel display
The lane keeping assist function is
active.
Dynamic radar cruise control
display
Lane line display
When thin lines are shown:
A lane marker is not recognized by
the system, or the LKA system
functions are temporarily can-
celed.
When solid lane lines are shown:
The lane departure warning func-
tion is active.
■Temporary cancellation of the LKA system functions
If any of the following occurs, the LKA system functions will be temporarily can-
celed. The functions will resume after the necessary operating conditions have
returned.
●The turn signal lever is operated.
●The steering wheel is turned as far as necessary to cause the vehicle to change
lanes.
●The brake pedal is depressed.
However, the lane keeping assist function will not resume even after the brake
pedal is released because depressing the brake pedal also cancels the dynamic
radar cruise control. (only lane departure warning function will resume)
●The vehicle speed deviates from the operating range of the LKA system func-
tions.
