GM Service Manual Online
For 1990-2009 cars only

Before you get out of your manual transmission vehicle, put your shift lever in 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, remove the key and release the clutch.

If you have four-wheel drive, be sure your transfer case is in a drive gear. Your vehicle could roll if it isn't.

If you are towing a trailer, see Towing a Trailer .
