TOYOTA SAFETY SENSE™
LDA in TSS 2.0 uses a forward-facing camera designed to detect visible white and
yellow lane markers or road edge in front of the vehicle and the vehicle’s position
on the 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 (50 km/h) or higher
on relatively straight roadways.
In addition to the alert function, LDA w/SA also features a steering assist
function. When enabled, if the system determines that the vehicle is on a path to
unintentionally depart from its lane, the system may provide small corrective steering
inputs to the steering wheel for a short period of time to help keep the vehicle in its
lane.
If the vehicle repeatedly deviates from the lane, the vehicle drifts within the lane due
to inattention, or the driver abruptly operates the steering wheel after an inattentive
period, when enabled, the vehicle sway warning function alerts the driver with an
audio and visual alert, urging them to take a break.

Refer to the Toyota Owner’s Manual for additional information on LDA operation,
settings adjustments, limitations, and precautions before attempting to use it.
