WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) 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 SRS. 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.
NOTE: There are provisions for up to three bulb/bulb holder units on the Compass Mini-Trip Computer (CMTC) circuit board. The two
outboard bulbs illuminate the CMTC push buttons, while the center bulb illuminates the optional universal transmitter push buttons.
Therefore, the center bulb location is only populated on vehicles equipped with the optional universal transmitter.
