Installation

NOTE: Before installing the steering wheel, make sure

the front wheels are straight ahead.

CAUTION:

• Be sure to install the harness wires so that they are

not pinched or interfering with other car parts.

• Do not replace the original steering wheel with any

other design, since it will make it impossible to prop-

erly install the airbag. (Use only genuine Honda

replacement parts.)

• After reassembly, confirm that the wheels are still

straight ahead and that steering wheel spoke angle

is correct. If minor spoke angle adjustment is neces-

sary, adjust the tie-rods only. Do not remove and

reposition the steering wheel.

Confirm that the airbag assembly is securely

attached to the steering wheel; otherwise, severe per-

sonal injury could result during later airbag deploy-

ment.

1. Before installing the steering wheel, center the

cable reel.

Do this by first rotating the cable reel clockwise

until it stops.

Then rotate it counterclockwise (approximately two

turns) until:

— The yellow gear tooth lines up with the mark on

the cover.

— The arrow on the cable reel label points straight

up.

NOTE: Be sure the steering wheel shaft engages

the cable reel.

9. Connect the battery positive terminal, and then con-

nect the negative terminal.

10. After installing the airbag assembly, confirm proper

system operation:

• Turn the ignition to II: the instrument panel SRS

indicator light should come on for about six sec-

onds and then go off.

• Confirm operation of horn buttons.

• Confirm operation of cruise control set/resume

switch.

• Turn the steering wheel counterclockwise and

make sure the yellow gear tooth still lines up

with the alignment mark.
