Jeep Grand Cherokee WK. Manual — part 421
ASSEMBLY
WARNING: On vehicles equipped with airbags, disable the supplemental restraint system before attempting
any steering wheel, steering column, driver airbag, passenger airbag, seat belt tensioner, side curtain air-
bag, front impact sensor, side impact sensor, or instrument panel component diagnosis or service. Discon-
nect 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 supple-
mental restraint system. Failure to take the proper precautions could result in accidental airbag deployment
and possible personal injury.
WARNING: On vehicles equipped with the premium instrument cluster, the cluster circuitry provides an
alternating current to supply power to the electro-luminescent illumination lamp through a pigtail wire and
connector that is accessible at the back of the cluster housing. Use proper precautions when handling this
unit during diagnosis or service to avoid electrical shock and possible personal injury.
