Towing a Trailer
NOTICE:
~~~
Pulling a trailer improperly can damage your vehicle and result
in costly repairs not covered by your warranty. To pull a trailer
correctly, follow the advice in this part, and see your GM dealer
for important information about towing a trailer with your
vehicle.
Most vehicles are ready for some trailer towing. If yours was built with
trailering options, as many are, it's ready for heavier trailers. But trailering
is different than just driving your vehicle by itself. Trailering means changes
in handling, durability, and fuel economy. Successful, safe trailering takes
correct equipment, and it has to be used properly.
That's the reason for this part. In it are many time-tested, important
trailering tips and safety rules. Many of these are important for your safety
and that of your passengers. So please read this section carefully before you
pull a trailer.
