Torque Lock If you are parking on a hill and you don't shift your transaxle into PARK (P) properly, the weight of the vehicle may put too much force on the parking pawlin the transaxle. You may find it difficult to pull the shift lever out of PARK (P). This is called "torque lock." To prevent torque lock, set the parking brake and then shift into PARK (P) properly before you leave the driver's seat. To find out how, see "Shifting Into PARK (P)" in the Index. When you are ready to drive, move the shift lever outof PARK (P) befure you release the parking brake. If torque lock does occur, you may need have another to vehicle push yours a little uphillto take some of the pressure from the transaxle, so you can pull the shift lever out of PARK(P). Shifting Out of PARK (P) Your Buick has a brake-transaxle shift interlock. You have to fully apply your regular brakebefore you can shift from PARK (P) when the ignition is in the RUN position. See "Automatic Transaxle" in the Index. If you cannot shift out of PARK (P), ease pressure on the shift lever-- push the shiftlever 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 still can I but shift out ofPARK (P), try this: 1. Turn the key to OFF. Open and close the driver's door to turn off the Retained Accessory Power feature (if equipped). 2. Apply and hold the brake until the end of Step 4. 3. Shift to NEUTRAL (N). 4. Start the vehicle and then shift to thedrive gear you want. 5. Have the vehicle fixed as soon as you can.
