1995 Buick LeSabre Owner's Manual - Page 180

Don't have your vehicle towed on the front wheels, unless you must. If the vehicle must be towed on the front wheels, don't go more than 55 mph (88 kph) or farther than 500 miles (800 km) or your transaxle will be damaged. If these limits must be exceeded, then the front wheels have to be supported on a dolly. When your vehicle is being towed, have the ignition key off. The steering wheel should be clamped in a straight-ahead position, with a clamping device designed fortowing service. Do not use the vehicle's steering columnlock for this. The transaxle should be in NEUTRAL (N) and the parking brake released.
