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, impaired driving,

Fuel Additives
TOP TIER Detergent Gasoline

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.

instructions on the fuel
pump island.
.Turn off the engine when
refueling.

(Continued)
Warning (Continued)
.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.

happen if the tank is
nearly full, and is more
likely in hot weather. Insert
the fill nozzle slowly and
