WARNING
■Cautions regarding the use of the sys-
tem

driving. Always driv e safely, taking care
to observe your surroundings.

plementary function which alerts the
driver that a vehicle is present in the blind
spot. Do not overly rely 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.
According to conditions, the system may
not function correctly. Therefore the
driver’s own visual confirmation of safety
is necessary.
