Downloaded from www.Manualslib.com manuals search engine across an incline, the much more narrow track width (the distance
between the left and right wheels) may not prevent the vehicle from
tilting
and rolling over. Also, driving across an incline puts more
weight on the downhill wheels. This could cause a downhill slide or a
rollover.
0 Surface conditions can be a problem when you drive across a hill.
Loose gravel, muddy spots, or even wet grass can cause your tires to
slip sideways, downhill. If
the vehicle slips sideways, it can hit
something that will trip it (a rock, a rut, etc.) and roll over.
Hidden obstacles can make the steepness of the incline even worse. If
you drive across a rock with the uphill wheels, or if the downhill
wheels drop into a rut or depression, your vehicle can
tilt even more.
For reasons like these, you need to decide carefully whether to try to drive
across an incline. Just because the trail goes across the incline doesn’t mean
you have to drive it. The last vehicle to try it might have rolled over.
Q: What if I’m driving across an incline that’s not too steep, but I hit
some
loose gravel and start to slide downhill. What should I do?
A: If you feel your vehicle starting to slide sideways, turn downhill. This
should help straighten out the vehicle and prevent
the side slipping.
However,
a much better way to prevent this is to get out and “walk the
course”
so you know what the surface is like before you drive it.
Stalling on an Incline
If your vehicle stalls when you’re crossing an incline, be sure you (and your
passengers) get out on the uphill side, even
if the door there is harder to
open.
If you get out on the downhill side and the vehicle starts to roll over,
you’ll be right
in its path.
If you have to walk down the slope, stay out of the path the vehicle will take
if it does roll over.

Downloaded from www.Manualslib.com manuals search engine 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.
These grades are molded on the sidewalls of passenger car tires.
While
the tires available as standard or optional equipment on General
Motors vehicles may vary with respect to these grades, all such tires meet
General Motors performance standards and have been approved for
use on
General Motors vehicles.
All passenger type (P Metric) tires must conform
to Federal safety requirements in addition to these grades.
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.
In most cases, you will not need
to have your wheels aligned again.
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 GM dealer if any of
these conditions exist.
Your dealer 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
vehicle.
