Parking the Vehicle Manual Transmission

If the vehicle has a manual transmission, before you get out of the vehicle, move the shift lever into R (Reverse), and firmly apply the parking brake. Once the shift lever has been placed into R (Reverse) with the clutch pedal pressed in, turn the ignition key to LOCK/OFF, remove the key and release the clutch.

If you are parking on a hill, or if the vehicle is pulling a trailer, see Towing a Trailer .
