Shifting Out of Park (P) (Automatic Transmission) Your vehicle has an automatic transmission shift lock control system which locks the shift lever in PARK (P) when the ignition is in the LOCK position. In addition, you have to fully apply the regular brakes before you can shift from PARK (P) when the ignition is in ON. See Automatic Transmission Operation on page 120. If you cannot shift out of PARK (P), ease pressure on the shift lever by pushing the shift lever all the way into PARK (P) as you maintain brake application. Then, move the shift lever into the gear you want. If you ever hold the brake pedal down but still cannot shift out of PARK (P), try this: 1. Turn the key to ACC. There is no shift interlock in this key position. 2. Apply and hold the brake until the end of Step 4. 3. Shift the transmission to NEUTRAL (N). 4. Start the vehicle and then shift to the gear you want. 5. Have the system fixed as soon as you can. 134 Parking Your Vehicle (Manual Transmission) Your vehicle has a manual transmission. Before you get out of your vehicle, move the shift lever into REVERSE (R), and firmly apply the parking brake. Once the shift lever has been placed into REVERSE (R) with the clutch pedal pressed in, turn the ignition key to LOCK, remove the key and release the clutch. If you are parking on a hill, or if your vehicle is pulling a trailer, see Towing a Trailer on page 305.
