Chevrolet VENTURE 1998 Manual page 306

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.
~~
NOTICE:
If you are using car-carrier equipment, you must
pull the Electronic Level Control (ELC) fuse, in
the instrument panel fuse block, before securing
the vehicle.
Damage to the shocks or leveling system may
occur if the Electronic Level Control (ELC) fuse
is not disabled.
When your vehicle is being towed, have the ignition key
in OFF. 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. For front towing, the
transaxle should be in PARK (P) and the parking brake
released. For rear towing, the transaxle should be in
NEUTRAL (N) and the parking brake engaged.
