TOYOTA SAFETY SENSE
DISABLING THE PRE-COLLISION SYSTEM (PCS)
Press the PCS switch for 3 seconds or more to turn it off. The warning light and
message displays in the MID. Depress it again to turn it back on.
Note: The system is enabled each time the power switch is turned to ON
mode.
Refer to a Toyota Owner's Manual for additional information on PCS operation,
settings adjustments, limitations, and precautions before attempting to use it.
Lane Departure Alert with
Steering Assist function (LDA w/SA)
LDA in TSS-P 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 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.
