spot. Do not overly re ly on the Blind Spot
Monitor function. The function cannot
judge if it is safe to change lanes, there-
fore over reliance could cause an acci-
dent resulting in death or serious injury.

not function correctly. Therefore the
driver’s own visual confirmation of safety
is necessary.
