WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the supplemental restraint system before attempting
any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect
and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further
diagnosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the proper precautions could result
in accidental airbag deployment.
CAUTION: Always use the correct bulb size and type for replacement. An incorrect bulb size or type may overheat and cause damage to the
lamp, the socket or the lamp wiring.

is only populated on vehicles equipped with the optional universal transmitter.
