NOTE
If your vehicle deviates from its traffic lane, the LDWS operates (warning sound and indicator
l
light). Steer the vehicle adequately to drive the vehicle to the center of the lane.
When the turn signal lever is operated for a lane change, the LDWS warning is automatically
l
canceled. The LDWS warning becomes operable when the turn signal lever is returned and the
system detects the white or yellow lines.
If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the vehicle moves
l
close to a white or yellow line, the system determines that the driver is making a lane change and
the LDWS warning is automatically canceled.
The LDWS may not operate during the period immediately after the vehicle has deviated from its
l
lane and the LDWS has operated, or the vehicle deviates from its lane repeatedly within a short
period of time.
The LDWS does not operate if it does not detect the white or yellow lines of the traffic lane.
