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).

• With the key access ignition system, the ignition key should come out only in LOCK/OFF.

See Ignition Positions (Key Access) or Ignition Positions (Keyless Access).

Contact your dealer if service is required.
