When it is judged that there is a malfunction in the system relating to steering
control function, the steering control function is canceled and “LDA Steering
Assist Deactivated Warnings Available” is displayed on the multi-information dis-
play. However, it is possible that the lane deviation alert function operates.
When the steering control function is canc eled, it will not return unless “Steering
Assist” is turned “On” again from the “S ettings display” of the multi-information
display ( P. 267) or the LDA switch is turned on again.
When the both lane lines turn white:
Indicates that both right and left lane
markers are recognized.
If the vehicle deviates from the traffic
lane, the lane displa y on the side the
vehicle has deviated from will flash in
orange. ( P. 2 6 2 )
When the either lane line turns white:
Indicates that the lane marker on the
white-marked side is recognized.
If the vehicle deviates from the side of a
lane with recognized lane markers, the
lane line will flash in orange. ( P. 2 6 2 )
When the inside of both lane lines are
black:
Indicates that no lane markers are rec-
ognized or the LDA is temporarily can-
celed.

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.)

■Before using the LDA
Do not over rely on the LDA. The LDA does not drive the vehicle automatically, nor
does it reduce the amount of care you need to take. As such, the driver must always
assume full responsibility for understandin g his/her surroundings, for operating the
steering wheel to correct the driving line, and for driving safely. Also, take occasional
rests from fatigue due to driving over long periods of time, etc.
Inappropriate or negligent driving co uld lead to an unexpected accident.
■Do not drive without holding the steering wheel
While the steering control function is operating, when the system judges that the vehi-
cle is being driven without holding the steering wheel, a warning message is displayed.

Inappropriate steering wheel operations an d/or negligent driving could lead to an
unexpected accident. When driving, firmly ho ld the steering wheel and keep safe driv-
ing in mind.
■To avoid operating the LDA by mistake
Switch the LDA off using the LDA switch when not in use. ( P. 2 6 3 )
