Steering Wheel
Removal
SRS components are located in this area. Review the
SRS component locations, precautions, and procedures
in the SRS section (24) before performing repairs or ser-
vice.
1. Align the front wheels straight ahead. then remove
the driver's airbag assembly (see section 24) from
the steering wheel.
2. Disconnect the horn connector and cruise control
switch connectors.
CONTROLSWITCHES CONNECTOR
3. Loosen the steering wheel bolt, then install a steering
wheel puller on the steering wheel and remove it.
Note these items when removing the steering wheel:
. Do not tap on the steering wheel or the steering
column shaft when removing the steering wheel.
. lf you thread the puller bolts into the wheel hub
more than five threads, the bolts will hit the cable
reel and damage it. To prevent this, install a pair
of jam nuts five threads up on each puller bolt.

lnstallation
1. Before installing the steering wheel, make sure the
front wheels are aligned straight ahead, then center
the cable reel. Do this by first rotating the cable reel
clockwise until it stops. Then rotate it counterclock-
wise approximately two turns. The arrow mark on
the cable reel label should point straight up.

2. Install the steering wheel on to the steering column
shaft, making sure the steering wheel shaft engages
the cable reel and canceling sleeve. Do not tap on
the steering wheel or steering column shatt when
instailing the steering wheel
HOLE
Install the steering wheel bolt, and tighten it to 39
N.m (4.0 kgf.m, 29 lbf.ft).
Connect the horn connector and the cruise control
switch connectors,
Install the driver's airbag assembly, and confirm
proper system operation (see section 24).
