Please tell or remind anyone who works on your Cadillac that it has the
air bag system. There are parts of the air bag system in several places
around your vehicle. You don’t want the system to inflate while someone
is working on your vehicle. The air bag system does not need regular
maintenance. Your Cadillac dealer and the

procedures.

When electrical work is done under the hood or inside your vehicle, the
ignition should be in “Lock”
if possible. Avoid wires wrapped with yellow
tape, or yellow connectors. They are probably part of the air bag system.
Your vehicle has a driver’s air bag and a right front passenger’s air bag.
Both air bags must be disconnected

electrical work or if the steering column is to be disassembled.
Disconnect both air bags like this:
Turn off the ignition.

inflatable restraint light on the instrument panel. If you don’t see this
light flash and then go out as usual, have your air bag system repaired.

FUEL
Use regular unleaded gasoline rated at 87 octane or higher. It should
meet specifications
ASTM D4814 in the U.S. and CGSB 3.5-92 in
Canada. These fuels should have the proper additives,
so you should not
have to add anything to the fuel.
1 the U.S. and Canada, it’s easy to be sure you get the right kind of
gasoline (unleaded). You’ll see
“UNLEADED” right on the pump. And
only unleaded nozzles will fit into your vehicle’s filler neck.
Be sure the posted octane is at least
87. If the octane is less than 87, you
may get a heavy knocking noise when you drive. If it’s bad enough, it can
damage your engine.
If you’re using fuel rated at
87 octane or higher and you still hear heavy
knocking, your engine needs service. But don’t worry if you hear a little
pinging noise when you’re accelerating
or driving up a hill. That’s normal,
