1995 GMC Jimmy Owner's Manual - Page 81

If you have four-wheel drive with a manual transfer case shift lever and your transfer case is in NEUTRAL (N), your vehicle will be freeto roll, even if your shift lever is in PARK (P). So, be sure the transfer case is in a drive gear - not in NEUTRAL (N). Always set your parkingbrake. Follow the proper steps to be sure your vehicle won't move. See "Shifting Into PARK (P)" in the Index. If you're pulling a trailer, see "Towing a Trailer" in the Index. All- Wheel Drive (Option) If your vehicle has all-wheel drive, your engine's driving power is sent to all four wheels for extra traction. This is like four-wheel drive, but there is no lever or switch to engage or disengage the front axle. It is fully automatic and adjusts itselfas needed for road conditions. 2-29
