When the OCS senses that the front-
passenger seat occupant is classified as
being heavier than the weight of atypical 12-
month-old child seated in astandar dchild
restraint or as being asmall individual (such
as ayoung teenager or asmall adult), the
000E0013 indicator lamp willi lluminate for
approximatel y6seconds when the engine is
started and then ,depending on occupant
weight sensor readings from the front-
passenger seat, remain illuminated or go out.
With the 000E0013 indicator lamp

is deactivated. With the 000E0013indicator
lamp out, the front-passenge rfront air bag is
activated.
When the OCS senses that the front-

If the 000E0013 indicator lamp is illuminated,
the front-passenger fron tair bag is

R in the even tofcertain frontal impacts
R if impact exceeds apreset deployment
threshold
R independently of the side impact air bags
