Towing Your
Car
Try to have a
GM
dealer or a professional towing
service tow your Buick. The usual towing equipment is
a sling-type (A) or a wheel-lift (B)
or car carrier (C) tow
truck.
If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like fog
lamps, aero skirting, or special tires and wheels, these
instructions and illustrations may not be correct.
Before you do anything, turn on the hazard warning
flashers.
When you call, tell.the towing service:
That your vehicle has rear-wheel drive.
The make, model, and year of- your vehicle.
Whether you can still move the shift lever.
If there was an accident, what was damaged.
When the towing service arrives, let the tow operator
know that this manual contains detailed towing
instructions and illustrations. The operator may want to
see them.
