Driving Information
Driver Behavior
Driving is an important responsibility. Driver
behavior, the driving environment, and the
vehicle's design all affect how well a vehicle
performs.
Being aware of these factors can help in
understanding how the vehicle handles and
what can be done to avoid many types of
crashes, including a rollover crash.
Most serious injuries and fatalities to
unbelted occupants can be reduced or
prevented by the use of seat belts. In a
rollover crash, an unbelted person is
significantly more likely to die than a
person wearing a seat belt. In addition,
avoiding excessive speed, sudden or abrupt
turns, and drunken or aggressive driving can
help make trips safer and avoid the
possibility of a crash.
Driving Environment
Be prepared for driving in inclement
weather, at night, or during other times
where visibility or traction may be limited, such as on curves, slippery roads, or hilly
terrain. Unfamiliar surroundings can also
have hidden hazards.
Learn more about driving in different
conditions and off-road driving in this
section.
Vehicle Design
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
This is because they have a higher ground
clearance and a narrower track or shorter
wheelbase than passenger cars, which makes
them more capable for off-road driving.
While these design characteristics provide
the driver with a better view of the road,
these vehicles do have a higher center of
gravity than other types of vehicles.
A utility vehicle does not handle the same
as a vehicle with a lower center of gravity,
like a car, in similar situations.
Safe driver behavior and understanding of
the environment can help avoid a rollover
crash in any type of vehicle, including utility
vehicles.

Vehicle Care 303
Your dealer will know the kind of wheel that
is needed.
Each new wheel should have the same
load-carrying capacity, diameter, width,
offset, and be mounted the same way as
the one it replaces.
Replace wheels, wheel bolts, wheel nuts,
or Tire Pressure Monitor System (TPMS)
sensors with new GM original equipment
parts.
{Warning
Using the wrong replacement wheels,
wheel bolts, or wheel nuts can be
dangerous. It could affect the braking and
handling of the vehicle. Tires can lose air
and cause loss of control, resulting in a
crash. Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.
Caution
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.
Used Replacement Wheels
{Warning
Replacing a wheel with a used one is
dangerous. How it has been used or how
far it has been driven may be unknown.
It could fail suddenly and cause a crash.
When replacing wheels, use a new GM
original equipment wheel.
Tire Chains
{Warning
Do not use tire chains. There is not
enough clearance. Tire chains used on a
vehicle without the proper amount of
clearance can cause damage to the
brakes, suspension, or other vehicle parts.
The area damaged by the tire chains
could cause loss of control and a crash.(Continued)
Warning (Continued)
Use another type of traction device only
if its manufacturer recommends it for the
vehicle's tire size combination and road
conditions. Follow that manufacturer's
instructions. To avoid vehicle damage,
drive slow and readjust or remove the
traction device if it contacts the vehicle.
Do not spin the wheels. If traction
devices are used, install them on the
front tires.
If a Tire Goes Flat
It is unusual for a tire to blow out while
driving, especially if the tires are maintained
properly. SeeTires0287. If air goes out of a
tire, it is much more likely to leak out
slowly. But if there is ever a blowout, here
are a few tips about what to expect and
what to do:
If a front tire fails, the flat tire creates a
drag that pulls the vehicle toward that side.
Take your foot off the accelerator pedal and
grip the steering wheel firmly. Steer to
maintain lane position, and then gently
brake to a stop, well off the road,
if possible.
