1. Verify the alignment of the gear (1) in the ignition switch (2). If gear (1) is not in position shown, turn

gear in ignition switch (2) until you reach the correct position.

IMPORTANT: The gears between the ignition switch and the lock cylinder housing must

be in the correct position. Failure to do so will cause a misalignment of
the gears in the ignition switch and the lock cylinder housing, which may
result in a NO START or BATTERY DRAIN.
