Parking the Vehicle Manual Transmission

If you have 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, you can turn the ignition key to OFF, 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 .
