58. CENTER SPIRAL CABLE
(a) Check that the front wheels are facing straight ahead.
(b) Turn the cable counterclockwise by hand until it becomesharder to turn.
(c) Then rotate the cable clockwise about 2.5 turns to align the marks.
HINT:
The cable will rotate about 2.5 turns to either left or right of the
center.
59. INSTALL STEERING WHEEL ASSY
(a) Align matchmarks on the steering wheel and main shaft assembly.
(b) Install the steering wheel set nut. Torque: 50 N´m (510 kgf´cm, 37 ft´lbf)
(c) Connect the connector.
60. INSTALL HORN BUTTON ASSY
NOTICE:

Never use airbag parts from another vehicle. When
replacing parts, replace with new ones.

Make sure the horn button assy is installed with the
specified torque.

If the horn button assy has been dropped, or there are
cracks, dents or other defects in the case or connec-
tor, replace the horn button assy with a new one.

When installing the horn button assy, take care that
the wirings do not interfere with other parts and that
they are not pinched between other parts.
(a) Connect the terminal.
(b) Connect the airbag connector.
(c) Install the steering horn button assy after confirming that the circumference groove of the torx screws is caught on
the screw case.
(d) Using a torx socket wrench, torque the 2 screws. Torque: 8.8 N´m (90 kgf´cm, 78 in.´lbf)

STEERING SYSTEM
PRECAUTION
1. HANDLING PRECAUTIONS ON STEERING SYSTEM
(a) Be careful to replace the parts properly because they could affect the performance of the steering sys-
tem and result in a driving hazard.
2. HANDLING PRECAUTIONS ON SRS AIRBAG SYSTEM
(a) The vehicle is equipped with SRS (Supplemental Restraint System) such as \
the driver airbag and front passenger airbag. Failure to carry out service operation in the correct sequence \
could cause the SRS
to unexpectedly deploy during servicing, possibly leading to a serious acc\
ident. Before servicing (in-
cluding removal or installation of parts, inspection or replacement), be sure \
to read the precautionary
notices in the supplemental restraint system (See page 60±1).
3. HANDLING PRECAUTIONS ON STEERING COLUMN
(a) Do not give an impact to the steering column assy, especially the motor and the torque sensor. If a great impact is given (dropping it to the floor, etc.), replace it with a new one.
(b) When removing the steering column assy, do not pull the harness.
(c) When having replaced the steering column assy and/or the ECU, calibrate the \
zero point of the steer- ing torque sensor.
(d) In the case of disconnecting a connector related to the power steering sys\
tem, turn the ignition switch ON, set the steering wheel in the straight±ahead position and turn th\
e ignition switch OFF before dis-
connecting the connector.
(e) In the case of connecting a connector related to the power steering system, make sure that the ignit\
ion switch is OFF at first. After connecting the connector, set the steering wheel assy in the straight±ahead
position, and then turn the ignition switch ON.
NOTICE:
Never turn on the ignition switch when the steering wheel assy is set in orde\
r than the straight±ahead
position.
(f) If the above operation is not done, the zero point of the steering torque \
sensor is shifted away from the proper position, making difference in the steering effort between right and left. If this happens, per-
form the zero point calibration of the steering torque sensor (See page 05±1042).
