Press the LDA switch to turn the LDA system on. Depress again to turn it\

Note: Operation of the LDA system and setting adjustments continues in t\
he 
same condition regardless of Ignition cycle until changed by the driver \

Refer to the Toyota Owner’s Manual for additional information on LDA \
operating 
conditions, system operation, settings adjustments, limitations, and pre\
cautions

LDA in TSS-C uses an in-vehicle camera designed to detect visible white \
and yellow 
lane markers in front of the vehicle and the vehicle’s position on th\
e road. If the system 
determines that the vehicle is starting to unintentionally deviate from \
its lane, the system 
alerts the driver with an audio and visual alert. When the alerts occur,\
 the driver must 
check the surrounding road situation and carefully operate the steering \
wheel to move 
the vehicle back to the center part of their lane. 
LDA is designed to function at speeds of approximately 32 MPH or higher \
on relatively 
straight roadways with a lane width of more than 9.8 ft.
Note: When operation conditions are no longer met, a function may be 
temporarily canceled. However, when the operation conditions are met aga\
in, 
operation of the function is automatically restored. For example, LDA ma\
y not 
function on the side(s) where white/yellow lines are not detectable.
Refer to the Toyota Owner’s Manual for additional information on LDA \
operating 
conditions, system operation, settings adjustments, limitations, and pre\
cautions 
before attempting to use it.
* A yellow LDA indicator indicates a malfunction and should be inspected\
 by your 
Toyota dealer.
