After disconnecting the cables, wait at least 30 seconds.

3. Turn the vehicle in neutral before assembling the clock spring

Warning

If the steering wheel and the front tires are not set straight ahead together, it may affect the number of circulation of steering wheel and damage the cable inside the clock spring. .

Damage to the clock spring may cause electric malfunctions in airbag warning lamp, horn, handsfree, auto cruise, heated wire and heated steering, and noise from turning the steering wheel.

Warning

Manually adjust the clock spring neutral way

1) Push the auto-lock button placed at the 6 o'clock position and turn it clockwise until it stops.

2) Push the auto-lock button placed at the 6 o'clock position and turn approximately 2 rotations counter-clockwise to align with the neutral mark (A).

4. Check the neutral state of the clock spring is attached to the steering column.
5. Connect the clock spring harness connector and horn harness connector to the clock spring.

Warning

Connect the connector until the lock 'clicks'.

6. Fit the steering column shroud panel.

   (Refer to Body - see "steering column shroud panel")

7. Fit the steering wheel.
