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 puttoo 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 out of PARK (P) before you release the parking brake. If torque lock does occur, youmay need to have another vehicle push yoursa little uphill to take some of the pressure from the parking pawl in the transaxle, so you can pullthe shift lever out of PARK (P). Shifting Out of PARK (P) Your vehicle hasa Brake-Transaxle Shift Interlock (BTSI). You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition is in RUN. As you step on the brake pedal, while in PARK (P), you may hear a click from the solenoid of the BTSI. This ensures that the BTSI is operating properly. See "Automatic TransaxleOperation" in the Index. If you cannot shift out of PARK (P), ease pressure on the shift lever -- push the shift lever all the way into PARK (P) as you maintain brake application. Then move theshift lever into the gear you want. If you ever hold the brake pedal down but still can't shift out of PARK (P), try this: 1. Turn the ignition key to OFF. 2. Apply and hold the brake until the end of Step 4. 3. Shift to NEUTRAL (N). 4. Start the engine and then shift to the drive gear you want. 5. Have the vehicle fixed as soon as you can. 2-37
