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.

238 Driving and Operating
occurs, return to your authorized
dealer for diagnosis. If it is
determined that the condition is
caused by the type of fuel used,
repairs may not be covered by the
vehicle warranty.
Fuels in Foreign
Countries (Gasoline)
The U.S., Canada, and Mexico post
fuel octane ratings in anti-knock
index (AKI). For fuel not to use in a
foreign country, see“Prohibited
Fuels” inFuel (Gasoline) 0236.
Fuel Additives
To keep fuel systems clean, TOP
TIER detergent gasoline is
recommended. See Fuel (Gasoline)
0 236.
If TOP TIER detergent gasoline is
not available, one bottle of GM Fuel
System Treatment Cleaner added to
the fuel tank at every engine oil
change, can help. GM Fuel System
Treatment Cleaner is the only gasoline additive recommended by
General Motors. It is available at
your dealer.
Fuel for Diesel Engines
The selection of a high quality fuel
is important for maintaining optimum
performance. Do not use diesel fuel
with more than 15 ppm sulfur
content. Do not use a diesel blend
containing more than 20% biodiesel
by volume. Both diesel and
biodiesel blends must meet all the
requirements as defined in the most
current versions of the local fuel
standards. See the recommended
fuels under
What Fuel to Use in the
U.S. (Diesel) 0239 andWhat Fuel
to Use in Canada and Mexico
(Diesel) 0240.
Caution
Engine damage may occur if
recommended fuels are not used,
which may void the vehicle
warranty. Some improper
fuels are:
. Diesel fuel with the addition
of gasoline.
. Diesel fuel mixed with
engine oil or automatic
transmission fluid.
. Triglyceride fuels, such as
raw vegetable oil or animal
fat, in any form, including
with blends of diesel or
biodiesel.
. Marine diesel fuel and
fuel oils.
. Diesel-water emulsions,
such as Aquazole.
