LDWS is activates.
Note:
1. Please measure front windshield viewing area, do not block the driver's forward
field of vision, and install the camcorder below rearview mirror (upper central of the
front windshield). We recommend that the sky and the ground occupied 50 % of the
video screen, install the bracket then adjust the camcorder to make the lane is
aligned to the lane alignment icon. Correct installation makes the camcorder to
maximize the efficiency and improve the accuracy of LDWS.
2. Make sure that traffic lane align icon will not be obscured other things (e.g. hood). It
may cause misjudgment if the endpoint is obscured.
