TURBO BOOST GAUGE
Your vehicle is equipped with a boost gauge that indi-
cates the intake manifold pressure relative to barometric
pressure. The engine management system in your vehicle
intelligently regulates intake manifold pressure based on
environmental (ambient) and engine operating condi-
tions. With the accelerator pedal fully depressed, it is
normal for the maximum intake manifold pressure
(boost) to vary from 11 to 15 psi.If low octane fuel (below the recommended 91 octane
(R+M)/2)) is used, boost will be reduced significantly.
Normal boost levels will return once the recommended
fuel is used and the engine controller adapts to the fuel
octane level.

SELECTING FUEL
2.4L TURBO
Your engine is designed to meet all emis-
sion regulations and provide excellent fuel
economy and performance when using
high quality unleaded gasoline having an
octane rating of 91. The purchase of higher
octane is not recommended.
High quality unleaded gasoline having a minumum
octane rating of 87 may safely be used for your vehicle.
Use of these lower octane gasolines, however, may result
in reduced acceleration performance.
If low octane fuel (below the recommended 91 octane
(R+M)/2)) is used, boost will be reduced significantly.
Normal boost levels will return once the recommended
fuel is used and the engine controller adapts to the fuel
octane level.
Spark Knock
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of“regular”gasoline be-
fore considering service for the vehicle.
Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) to define
fuel properties necessary to deliver enhanced emissions,
engine performance, and durability for your vehicle. The
manufacturer recommends the use of gasolines that meet
the WWFC specifications if they are available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning fuel referred to as Reformulated Gasoline. Re-
formulated gasolines contain oxygenates, and are specifi-
cally blended to reduce vehicle emissions and improve
air quality.
STARTING AND OPERATING 121

The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability for the engine
and fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with mate-
rials called oxygenates such as 10% ethanol, MTBE and
ETBE. Oxygenates are required in some areas of the
country during the winter months to reduce carbon
monoxide emissions. Fuels blended with these oxygen-
ates may be used in your vehicle.
CAUTION!
DO NOT use gasolines containing Methanol. Gaso-
line containing methanol may damage critical fuel
system components.
Problems that result from using methanol/gasoline
blends are not the responsibility of the manufacturer.
While MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
MMT in Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasolines
blended with MMT provide no performance advantage
beyond gasolines of the same octane number without
MMT. Gasolines blended with MMT have shown to reduce
spark plug life and reduce emission system performance in
some vehicles. The manufacturer recommends that gaso-
lines free of MMT be used in your vehicle. The MMT
content of gasoline may not be indicated on the gasoline
pump, therefore you should ask your gasoline retailer
whether or not his/her gasoline contains MMT.
It is even more important to look for gasolines without
MMT in Canada because MMT can be used at higher
levels than allowed in the United States.
MMT is prohibited in both Federal and California refor-
mulated gasolines.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
122 STARTING AND OPERATING

conditions and would result in unnecessary cost. There-
fore you should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
damage the emission control system.
•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
•The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most of these
products contain high concentrations of methanol.Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
