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.
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.

Caution (Continued)
.Fuel with a posted octane
rating of less than the
recommended fuel. Using this
fuel will lower fuel economy
and performance, and may
decrease the life of the
emissions catalyst.
Fuels in Foreign Countries
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 0226.
Fuel Additives
TOP TIER Detergent Gasoline is highly
recommended for use with your
vehicle. If your country does not have
TOP TIER Detergent Gasoline, add
ACDelco Fuel System Treatment Plus
−Gasoline to the vehicle’s gasoline fuel
tank at every oil change or 15 000 km
(9,000 mi), whichever occurs first. TOP
TIER Detergent Gasoline and ACDelco
Fuel System Treatment Plus−Gasoline will help keep your vehicle’s engine
fuel deposit free and performing
optimally.
Filling the Tank
An arrow on the fuel gauge indicates
which side of the vehicle the fuel door
is on. See
Fuel Gauge 0112.
{Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.
Follow these guidelines to help
avoid injuries to you and others:
. Read and follow all the
instructions on the fuel pump
island.
. Turn off the engine when
refueling.
. Keep sparks, flames, and
smoking materials away
from fuel.
(Continued)
Warning (Continued)
.Do not leave the fuel pump
unattended.
. Avoid using electronic devices
while refueling.
. Do not re-enter the vehicle
while pumping fuel.
. Keep children away from the
fuel pump and never let
children pump fuel.
. Before touching the fill
nozzle, touch a metallic
object to discharge static
electricity from your body.
. Fuel can spray out if the fill
nozzle is inserted too quickly.
This spray can happen if the
tank is nearly full, and is
more likely in hot weather.
Insert the fill nozzle slowly
and wait for any hiss noise to
stop before beginning to
flow fuel.
