Air Bag Off Light (If Equipped)
When you turn the right front passenger's air bag off,
this light will come on and stay on to remind you that
the air bag has been turned off. This light will go off
when you turn the air bag back on again. See "Air Bag
Off Switch" in the Index for more on this, including
important safety information.
