{CAUTION:
When you are doing this inspection, the vehicle

or others could be injured.
1. Before starting this check, be sure there is enough
room around the vehicle. It should be parked on a

Ignition Transmission Lock Check
While parked, and with the parking brake set, try to turn

For manual transmission vehicles, the ignition key
should come out only in LOCK/OFF.
Turn the steering wheel to the left and to the right.
It should only lock when turned to the right. Contact
