Driving Across an Incline
Sooner or later, an off-road trail will probably go across the incline of a hill.
If this happens, you have to decide whether to
try to drive across the incline.

Here are some things to consider:
A hill that can be driven straight up or down may be too steep to drive
across. When you go straight up or down
a hill, the length of the wheel
base (the distance from the front wheels to the rear wheels) reduces the
likelihood the vehicle
will tumble end over end. But when you drive
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.
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.
A CAUTION:
Driving across an incline that’s too steep will make your v\
ehicle
roll over.
You could be seriously injured or killed. If you have
any doubt about the steepness of the incline, don’t drive a\
cross
it. Find another route instead.
0: 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.

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.
A CAUTION:
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.
NOTICE:
The wrong wheel can also cause problems with bearing life,
brake cooling, speedometer/odometer calibration, headlamp
aim, bumper height, vehicle ground clearance, and tire or tire
chain clearance to the body and chassis.
