Vehicle Design
According to the U.S. Department of Transportation,
utility vehicles have a signicantly higher rollover
rate than other types of vehicles. Utility vehicles do
have higher ground clearance and a narrower track or
shorter wheelbase than passenger cars, to make
them more capable for off-road driving. Specic design
characteristics like these give the driver a better
view of the road, but also give utility vehicles a higher
center of gravity than other types of vehicles. This
means that you should not expect a utility vehicle to
handle the same way a vehicle with a lower center
of gravity, like a car, would in similar situations.
But driver behavior factors are far more often the cause
of a utility vehicle rollover than are environmental or
vehicle factors. Safe driver behavior and understanding
the environment in which you will be driving can help
avoid a rollover crash in any type of vehicle, including
utility vehicles.
Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start with a very important safety device in your
vehicle: Buckle up. SeeSafety Belts: They Are for
Everyone on page 1-22.
Defensive driving really means “be ready for anything.”
On city streets, rural roads or freeways, it means
“always expect the unexpected.”
Assume that pedestrians or other drivers are going to be
careless and make mistakes. Anticipate what they might
do. Be ready for their mistakes.
Rear-end collisions are about the most preventable of
accidents. Yet they are common. Allow enough following
distance. It is the best defensive driving maneuver, in
both city and rural driving. You never know when the
vehicle in front of you is going to brake or turn suddenly.
Defensive driving requires that a driver concentrate on
the driving task. Anything that distracts from the driving
task — such as concentrating on a cellular telephone call,
reading, or reaching for something on the oor — makes
proper defensive driving more difficult and can even
cause a collision, with resulting injury. Ask a passenger to
help do things like this, or pull off the road in a safe place
to do them yourself. These simple defensive driving
techniques could save your life.

{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 or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance and tire or tire chain
clearance to the body and chassis.
SeeChanging a Flat Tire on page 5-77for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used
or how far it’s been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
