FORD 2008 Explorer v.3 - Manual (Page 207)

Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the side airbag has
deployed, the airbag will
not function again. The side
airbag system (including the
seat) must be inspected and
serviced by an authorized
dealer . If the airbag is not
replaced, the unrepaired area will
increase the risk of injury in a
collision.
Safety Canopy™ system
Do not place objects or
mount equipment on or
near the headliner at the siderail
that may come into contact with a
deploying Safety Canopy™.
Failure to follow these instructions
may increase the risk of personal
injury in the event of a collision.
Do not lean your head on the door. The Safety Canopy™ could
injure you as it deploys from the headliner.
Do not attempt to service, repair, or modify the Safety Canopy™
system, its fuses, the A, B, or C pillar trim, or the headliner on a
vehicle containing a Safety Canopy™. See your authorized dealer.
