Try to have a GM dealer or a professional towing service tow your vehicle.
They can provide the right equipment and know how to tow it without
damage.
If your vehicle has been changed since
it
was factory-new by adding things
like fog lamps, aero skirting, or special tires and wheels, these things could
be damaged during towing.
Before you do anything, turn on the hazard warning flashers.
When you call, tell the towing service:
That your vehicle has rear-wheel drive, or that it has the four-wheel
drive option.

The make, model, and year of your vehicle.
Whether you can move the shift lever for the transmission and shift the
transfer case, if you have one.
If there was an accident, what was damaged.
