Chevrolet 1997 Monte Carlo Owner's Manual page 186

CAUTION:
A vehicle can fall from a car carrier if it isn't
adequately secured. This can cause a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before it is transported.
Don't use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks. They will damage drivetrain and
suspension components.
When your vehicle is being towed, have the ignition
turned to the OFF position. The steering wheel should
be clamped in a straight-ahead position, with a clamping
device designed for towing service. Do not use the
vehicle's steering column lock for this. The transaxle
should be in NEUTRAL (N) and the parking
brake released.
Don't have your vehicle towed on the dnve wheels,
unless you must. If the vehicle must be towed on the
drive wheels, be sure to follow the speed and distance
restrictions later in this section or your transaxle will be
damaged. If these limitations must be exceeded, then the
drive wheels have to be supported on a dolly.
