as specified by the (R+M)/2 method. The use of 89 octane
“Plus” gasoline is recommended for optimum perfor-
mance and fuel economy.
While operating on gasoline with an octane number of
87, hearing a light knocking sound from the engine is not
a cause for concern. However, if the engine is heard
making a heavy knocking sound, see your dealer imme-
diately. Use of gasoline with an octane number lower
than 87 can cause engine failure and may void or not be
covered by the New Vehicle Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before consid-
ering service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline”.Reformulated gasoline contains oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide im-
proved performance and durability of engine and fuel
system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as ethanol.
CAUTION!
DO NOT use gasoline containing methanol or gaso-
line containing more than 15% ethanol (E-15). Use of
these blends may result in starting and drivability
problems, damage critical fuel system components,

CAUTION!
•Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap.
•A poorly fitting fuel filler cap could let impurities
into the fuel system.
•A poorly fitting fuel filler cap may cause the
“Malfunction Indicator Light (MIL)” to turn on.
•To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. When the fuel
nozzle “clicks” or shuts off, the fuel tank is full.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
(Continued)
WARNING!(Continued)
•Never add fuel to the vehicle when the engine is
running.
•A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
NOTE:
•When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
•Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The MIL in the instrument cluster may turn
on if the gas cap is not secured properly. Make sure
that the gas cap is tightened each time the vehicle is
refueled.

reservoir with windshield washer solvent only (not ra-
diator antifreeze). When refilling the washer fluid reser-
voir, take some washer fluid and apply it to a cloth or
towel and wipe the wiper blades clean. This will help
blade performance.
To prevent freeze-up of your windshield washer system
in cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This
rating information can be found on most washer fluid
containers.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.After the engine has warmed up, operate the defroster for
a few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. Windshield
washer solution used with water as directed on the
container, aids cleaning action, reduces the freezing point
to avoid line clogging, and is not harmful to paint or trim.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep
into the passenger compartment. In addition, have the
