Essential Safety Equipment
SRS Air Bags
Rear-ending or running under a truck's
tail gate may not provide the stopping
force necessary for air bag deployment.
Non-activation of front air bags
Front air bags will not normally inflate in
the following cases:
Collision from the rear.
Impact to the side, but it may deploy
the side and curtain air bags.

and curtain air bags but not the front air
bags.
2-60
Side and curtain air bag activation
The severity of impact above the designed
threshold level to one side of the vehicle
(driver or passenger side areas) will cause
the side and curtain air bags on that side
to inflate, but it will not normally deploy
the front air bags.
Limitations to side and curtain air bag
activation
Depending on the severity of impact, the
side and curtain air bags may not inflate in
the following cases:
Frontal offset impact may not provide
enough side impact to deploy the side
and curtain air bags.
Side impacts involving trees or poles
can cause severe cosmetic damage but
may not have enough impact force to
activate the side and curtain air bags.
