Shifting Out of Park (P) Your vehicle has an automatic transmission shift lock control system. You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition is in ON. See Automatic Transmission Operation on page 2-26 for more information. If you cannot shift out of PARK (P), ease the pressure on the shift lever. Push the shift lever all the way into PARK (P) while pushing the button on the shift lever as you maintain brake application. Then move the shift lever into the gear you want. Shift Lock Release (Automatic Transmission) If your vehicle has a dead battery or a battery with low voltage, you can still shift the vehicle into PARK (P) and remove the ignition key. Use the following procedure to release the shift lever: 1. Pull up on the rear part of the leather boot that surrounds the shift lever. 2. Fold the boot upward to expose the mechanism beneath the shift lever. 2-37
