Driving and Operating 9-51
Recommended Fuel
If the vehicle has a V6 engine, use
regular unleaded gasoline with a
posted octane rating of 87 or higher.
If the octane rating is less than 87,
an audible knocking noise,
commonly referred to as spark
knock, might be heard when driving.
If this occurs, use a gasoline rated
at 87 octane or higher as soon as
possible. If heavy knocking is heard
when using gasoline rated at
87 octane or higher, the engine
needs service.
If the vehicle has the 6.2L V8 engine
(VIN Code P), use premium
unleaded gasoline with a posted
octane rating of 91 or higher. For
best performance, use premium
unleaded gasoline with a posted
octane rating of 93. In an
emergency, you can use regular
unleaded gasoline with an octane
rating of 87 or higher. If 87 octane
fuel is used, do not perform any
aggressive driving maneuvers such
as wide open throttle applications.You might also hear audible spark
knock during acceleration. Refill the
tank with premium fuel as soon as
possible to avoid damaging the
engine. If heavy knocking is heard
when using gasoline rated at
91 octane or higher, the engine
needs service.
Gasoline Specifications
(U.S. and Canada Only)
At a minimum, gasoline should meet
ASTM specification D 4814 in the
United States or CAN/CGSB‐3.5
or 3.511 in Canada. Some
gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. See
Fuel Additives
on page 9‑52 for additional
information.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See
the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle might fail a smog‐check test.
See Malfunction Indicator Lamp on
page 5‑19. If this occurs, return to
your authorized dealer for diagnosis.
If it is determined that the condition
is caused by the type of fuel used,
repairs might not be covered by the
vehicle warranty.

9-54 Driving and Operating
If the fuel cap is not installed
properly, the TIGHTEN GAS CAP
message will appear on the Driver
Information Center display. SeeFuel
System Messages on page 5‑36.
When reinstalling the cap, turn it
clockwise until it clicks once,
otherwise the Malfunction Indicator
Lamp could turn on. See
Malfunction Indicator Lamp on
page 5‑19.
{WARNING
Fuel can spray out on you if you
open the fuel cap too quickly.
If you spill fuel and then
something ignites it, you could be
badly burned. This spray can
happen if the tank is nearly full,
and is more likely in hot weather.
Open the fuel cap slowly and wait
for any hiss noise to stop. Then
unscrew the cap all the way. Be careful not to spill fuel. Do not
top off or overfill the tank and wait a
few seconds after you have finished
pumping before removing the
nozzle. Clean fuel from painted
surfaces as soon as possible. See
Exterior Care on page 10‑110.
When replacing the fuel cap, turn it
clockwise until it clicks once. Make
sure the cap is fully installed. The
diagnostic system can determine if
the fuel cap has been left off or
improperly installed. This would
allow fuel to evaporate into the
atmosphere. See
Malfunction
Indicator Lamp on page 5‑19.
{WARNING
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.
Leave the area immediately.
Notice: If a new fuel cap is
needed, be sure to get the right
type of cap from your dealer. The
wrong type of fuel cap might not
fit properly, might cause the
malfunction indicator lamp to
light, and could damage the fuel
tank and emissions system. See
Malfunction Indicator Lamp on
page 5‑19.
