Refueling from a service station pump
To refuel:
1. Open the fuel filler door. Do not refuel with
the engine running
3
2. Insert the pump's nozzle into the fuel filler
pipe's opening
as far as possible
(see the
illustration).
3. Avoid overfilling the fuel tank. Do not press
the handle on the filler nozzle after it has
stopped pumping. Too much fuel in the tank
in hot weather conditions can cause the fuel
to overflow. Overfilling could also cause dam-
age to the emission control systems.
CAUTION
Avoid spilling gasoline during refueling. In
addition to causing damage to the environ-
ment, gasolines containing alcohol can cause
damage to painted surfaces, which may not
be covered under the New Vehicle Limited
Warranty.

Keep your engine properly tuned. Certain
engine malfunctions, particularly involving the
electrical, fuel or distributor ignition systems,
may cause unusually high three-way catalytic
converter temperatures. Do not continue to
operate your vehicle if you detect engine
misfire, noticeable loss of power or other
unusual operating conditions, such as engine
overheating or backfiring. A properly tuned
engine will help avoid malfunctions that
could damage the three-way catalytic con-
verter.
•
Do not park your vehicle over combustible
materials, such as grass or leaves, which can
come into contact with the hot exhaust sys-
tem and cause such materials to ignite under
certain wind and weather conditions.
•
Excessive starter cranking (in excess of one
minute), or an intermittently firing or flooded
engine can cause three-way catalytic con-
verter or exhaust system overheating.
•
Remember that tampering or unauthorized
modifications to the engine, the Engine Con-
trol Module, or the vehicle may be illegal and
can cause three-way catalytic converter or
exhaust system overheating. This includes:
altering fuel injection settings or compo-
nents, altering emission system components
3 If the engine is running when the vehicle is refueled, the Check Engine Light (malfunction indicator lamp) may indicate a fault. However, your vehicle's performance will not be affected.
