3. Align the setting marks made when removing then
install steering wheel.
CAUTION: Never apply force to the steering wheel
shaft using a hammer or other impact tools in an
attempt to remove the steering wheel. The steering
shaft is designed as an energy absorbing unit.
4. Tighten the steering wheel fixing nut to the specified
torque.
Torque: 34 N´m (25 lb ft)
5. Support the inflator module and carefully connect the
SRS connector and horn lead.
NOTE: Pass the lead wire through the tabs on the plastic
cover (wire protector) of inflator to prevent lead wire from
being pinched.
6. Tighten bolts to specified torque.
Torque: 9 N´m (78 lb in)
7. Install driver knee bolster (reinforcement).
8. Install instrument panel lower cover then Install the
engine hood opening lever.
9. Connect the SRS connector.
10. Connect the battery ª-º terminal cable.

to become uncentered which will cause damage to
the coil assembly.
5. Remove the engine hood opening lever and steering
lower cover.
6. Remove driver knee bolster (reinforcement).
