4. Connect the horn connector.
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 driver's airbag assembly

is securely attached to the steering wheel; otherwise,

severe personal injury could result during later airbag

deployment.

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.
2. Install the steering wheel.

NOTE: Be sure the steering wheel shaft engages

the cable reel.

3. Attach the cruise control set/resume switches 4P

connector to the steering wheel clips.ProCarManuals.com
