Torque Lock If you are parking on a hill and you don't shift your transaxle into " P ' (Park) properly, the weight of the vehicle may put too much force on the parking pawl in the transaxle. You may find it difficult to pull the shift lever out of "P' (Park). This is called "torque lock." To prevent torque lock, set the parking brake and then shift into "P" (Park) properly before you leave the driver's seat. To find out how, see "Shifting Into 'P' (Park)" in the Index. When you are ready to drive, movethe shift lever out of "P" (Park) BEFORE you release the parking brake. If "torque lock" does occur, you may need to have another vehicle push yours a little uphill to take some of the pressure from the transaxle, so you can pull the shift lever out of "P' (Park). Shifting Out of 6 6P9 9 (Park) Your h i c k has a brake-transaxle shift interlock. You have to fully apply your regular brake before you can shift from " P ' (Park) when the ignition is in the "Run" position. See "Automatic Transaxle" in the Index. If you cannot shift out of T" (Park), easepressure on the shift lever -- push the shift lever all the way into "P" (Park) 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 can't shift out of "P" (Park), try this: 1, Turn the key to "Off." Open and close the driver's door to turn off the Retained Accessory Power feature, if you have it. 2. Apply and hold the brake until the end of Step 4. 3. Shift to "N" (Neutral). 4. Start the vehicle and then shift to the drive gear you want. 5. Have the vehicle fixed as soon as you can.
