A message sent out by NLETS (National Law Enforcement Telecommunications 
System) on December 12, 1997, at the request of the National Highway Traffic Safety Admin, stated: 

"NHTSA states that they have been unable to confirm any instances
of a slimjim triggering a side-impact airbag. NHTSA further states
that the vehicle manufacturers state that it is impossible to deploy an
airbag using a slimjim."
