Towing Your Vehicle
Try to have your 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 such
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.

device designed for towing service,

Towing From the Front
If you have a two-wheel drive vehicle, don’t have your vehicle towed on
the rear wheels, unless you must. If the vehicle must be towed on the rear
wheels, don’t
go more than 35 mph (56 km/h) or farther than 50 miles
(80 km) or your transmission will be damaged. If these limits must be
exceeded, then the rear wheels have to be supported on a dolly.
If your vehicle has
the four-wheel drive option and the transfer case is
engaged, a dolly must be used under the rear wheels when towing from the
front.

no longer have the overheat warning, you can drive. Just to be safe,
drive slower for about ten minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your vehicle right away.
If there’s still
no sign of steam, push the accelerator until the engine speed is
about twice as fast as normal idle speed. Bring the engine speed back to
normal idle speed after two or three minutes. Now see
