Leaving Your Vehicle With the Engine Running If you have to leave your vehicle with the engine running, be sure your vehicle is in PARK (P) and your parkingbrake is firmly set before you leave it. After you've moved the shift lever into the PARK (P) position, hold the regular brake pedal down. Then, see if you can movethe shift lever away from PARK (P) without first pulling it toward you. If you can, it means that the shift lever wasn't fully lockedinto PARK (P). Torque Lock If you are parking on a hill and you don'tshift your transmission into PARK (P) properly, the weight of the vehicle may puttoo much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of PARK (P). This is called "torque lock." To prevent torque lock, set theparking 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, you may need have another vehicle push to yours a littleuphill to take some of the pressure from the transmission, so you canpull theshift lever out of PARK (P). 2-23
