This lever allows steering wheel position to be locked when key switch is in LOCK position.

(7) Place ignition switch in LOCK position. The switch is in the LOCK position when column lock flag is parallel to ignition switch terminals (Fig. 41).

(8) Automatic Transmission Only: Apply a light coating of grease to park lock dowel pin and park lock slider linkage. Before installing switch, push the park lock slider linkage (Fig. 42) forward until it bottoms.

Do a final positioning by pulling it rearward about one-quarter inch.

(9) Apply a light coating of grease to both column lock flag and shaft at end of flag.

(10) Place ignition switch into openings on steering column.

(a) Automatic Transmission Only: Be sure park lock dowel pin on rear of ignition switch enters slot in park lock slider linkage (Fig. 42).

(b) Be sure flag on rear of switch is positioned above steering wheel lock lever (Fig. 43).

(c) Align dowel pins on rear of switch into holes on side of steering column.

(d) Install 3 ignition switch mounting screws.

Tighten screws to 2 N*m 6.5 N*m (17 in. lbs. 6 5 in. lbs.) torque.

(e) After installing ignition switch, rotate ignition key from LOCK to ON position. Verify that park lock slider moves in slider slot, allowing gearshift lever to be moved out of PARK (auto. trans.

only). If slider does not move, and gearshift lever is locked in PARK, the ignition switch park lock dowel pin, on rear of ignition switch, is not prop-erly installed in slot of park lock slider linkage.

Remove ignition switch and reinstall.

(11) Connect electrical connectors to ignition switch, halo lamp and (if equipped ), to "PRNDL".

Make sure that switch locking tabs are fully seated in wiring connectors.

(12) Install steering column covers (shrouds).

Tighten screws to 2 N*m (17 in. lbs.) torque.

(13) Install tilt column lever (if equipped).

(14) Connect negative cable to battery.

(15) Check for proper operation of halo light.

(16) Automatic Transmission Only: Shifter should lock in PARK position when key is in LOCK position (if equipped with shift lock device). Shifter should unlock when key rotated to ON position.

(17) Check for proper operation of ignition switch in ACCESSORY, LOCK, OFF, ON, RUN, and START positions.

(18) Steering wheel should lock when key is in LOCK position. Rotate steering wheel at least 180 to verify. Steering wheel should unlock when key is rotated to ON position.
