When the Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) OFF indicator light is turned on, press the switch and make sure that the indicator light turns off.

The Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) indication (white) is displayed in the multi-information display, and the system goes on stand-by.

Drive the vehicle in the center of the vehicle lane while the system is on standby. When all of the following conditions are met, the Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) indication (green) is displayed in the multi-information display, and the system becomes operational.

  • The engine is running.

  • The vehicle speed is about 60 km/h (37 mph) or faster.

  • The system detects white (yellow) lane lines on both the right and left sides.

  • The driver is operating the steering wheel.

  • The driving lane is neither narrow nor wide.

 

 

The Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) indication is white when the system detects only a white (yellow) line on either the left or right, and the indication changes to green when the system detects white (yellow) lines on both the left and right sides.

The Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) goes on stand-by status in the following cases:

  • The system cannot detect white (yellow) lane lines.

  • The vehicle speed is less than about 60 km/h (37 mph).

  • The ABS/TCS is operating.

  • The TCS is turned off.

    (If the TCS is turned off while the system is operational, a warning beep is heard and the system goes on standby.)

  • The vehicle is making a sharp curve.

  • The brake pedal is depressed.

  • The steering wheel is operated abruptly.

  • The width of a lane is excessively narrow or wide.

 

  • The Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) does not operate until the system detects white (yellow) lane lines on either the left or right.

  • When the system detects a white (yellow) lane line on one side only, the system will not operate the steering wheel operation assist and the warning for the lane line on the side that is not being detected. The steering wheel operation assist and the warning is only for a lane deviation on the side that is being detected.

  • If the driver takes his or her hands off the steering wheel (not holding the steering wheel), the warning sound is activated and an alert is indicated in the multi-information display or the active driving display.

     

    If the steering wheel is held lightly, or depending on the road conditions, the system may detect that you have released the steering wheel (not holding the steering wheel) even if you are holding it, and display a message in the multi-information display or the active driving display.

  • The timing at which the lane departure warning is activated and the steering wheel operation assist is performed varies.

  • The following settings for the Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) can be changed. Refer to Personalization Features (Search).
