Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer,
See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system and brake adjustment.
Each
of these is covered in this manual, and the Index
will help
you find them quickly. If you’re trailering, it’s
a good idea to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.

5. Raise the vehicle by rotating the wheel wrench to the
right on the jack. Raise the vehicle
far enough off the
ground so there’s enough room for the spare tire
to fit.
4. Remove all the wheel nuts and take off the flat tire.
7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
~ emergency, you can use a cloth or a paper towel
to do this; but be sure to use a scraper or wire
brush later,
if you need to, to get all the rust or
dirt off.
Never use oil or grease on studs or nuts.
If you
do, the nuts might come loose. Your wheel could
fall off, causing
a serious accident. 1
8. Place the spare tire on the wheel-mounting surface.

The grade C corresponds to a level of performance
which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades
B and A represent higher levels of performance on the
laboratory test wheel than the minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not
needed. However, if you notice unusual tire wear
or
your vehicle pulling one way or the other, the alignment
may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced. If the wheel
leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
retailer if any of these conditions exist.
lour retailer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as the one
it replaces.
If you need to replace any of your wheels, wheel
bolts or wheel nuts, replace them only with new GM
original equipment parts. This way, you will be sure to
have the right wheel, wheel bolts and wheel nuts for
your Aurora model.
T' 'Y:
Using the wrong replacement wheels, wheel bolts
or wheel nuts
on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use the correct wheel, wheel bolts and wheel nuts for
replacement.
