Ignition Transmission Lock Check

While parked, and with the parking brake set, try to turn the ignition to LOCK/OFF in each shift lever position.

○ The ignition should turn to LOCK/OFF only when the shift lever is in P (Park).
○ The ignition key should come out only in LOCK/OFF.

Contact your dealer if service is required.
