In steering control, the steering control
indicator will come on.
■If “Lane Departure Alert Malfunction Visit Yo ur Dealer” is displayed on the multi-infor-
mation display
Even if the LDA switch is pressed, when th e LDA indicator does not come on the system
may have a malfunction. Have the vehicle in spected by your Lexus dealer immediately.
■The steering control function
There are cases where it may be difficult to sense the steering force on the steering
wheel by the steering control, according to speed, the deviatio n situation, conditions of a
road, etc.
■Alert buzzer for lane deviation alert
Depending on the audio system sound level or air conditioning fan noise while the audio
system or air conditioning system is in use, it may be difficult to hear the alert buzzer.
■After the vehicle has been parked in the sun
The LDA may not be available and a warning message will be displayed for a while after
driving has started. When the temperature in the cabin decreases and the temperature
around the lane recognition camera ( P. 261) becomes suitable for its operation, turn
the LDA switch on again after a short time.
■ If there are lane markers on only one side of the vehicle
The lane deviation alert will not operate for the side on which lane markers could not be
recognized.
■Conditions in which the functi on may not operate correctly
In the following situations, the lane recognition camera may be unable to recognize lane
markers causing the lane deviation alert function to operate incorrectly. However, this
does not indicate a malfunction.
●When there are shadows on the road running parallel with lane markers, or if a shadow
covers the lane markers
●When driving through an area with no lane markers, such as a toll booth, a crossing or
before a ticket checkpoint
●When the lane markers are broken, Botts’ dots (raised pavement markers) or stones
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When driving on a road surface that is wet du e to rain, previous rainfall, standing water,
etc.
●When the lane markers are yellow (These may be more difficult for the system to rec-
ognize compared to white markers.)
