Parking the Vehicle Manual Transmission

Caution: Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the manual transmission is in gear. Your or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in NEUTRAL. See Parking Brake for more information.

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 LOCK, press the key release button, remove the key and release the clutch.

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