@ store a removed airbag assembly with
the pad surtace up. ll the airbag is improperly stored
tace down. accidental deployment could propel the unit
with snough force to cause serious iniury.

CAUTION:
. Before installing ths st€€ring wheel, align th€ front
wheels straight ahead.
. Be sure to ingtall the harnoss wirss 90 that they 8re
not pinched or intorfering with other car parts.
. Do not replace the original st€ering wheel with rny
other d8ign, since it will mako h impossiblo to p.op-

clockwise until it stoos. Then rotate it counterclock-
wise (approximately two turns) until. The arrow
make on the cable reel label points straight up.

shown. As the two connector halves are pressed
together, the sleeve is pushed back by the pawl.
NOTE: Do not touch the sleeve.

Attach the connector in the holder, then install the
access panel on the stee.ing wheel lower cover.
Connect the positive cable first. then the negative
cable to the battery.
After installing the airbag assembly, confirm proper
system operation:
. Turn the ignition switch ON (ll); the instrument
panel SRS indicator light should come on for
about six seconds and then go off.
. Confirm operation of horn buttons.
. Confirm operation of cruise control sevresume
