automatically. In addition, the “TPMS Telltale Light”
will turn off and the graphic in the EVIC will display
a new pressure value instead of dashes (- -), as long as
no tire pressure is below the low-pressure warning
limit in any of the four active road tires. The vehicle
may need to be driven for up to 20 minutes above
15.5 mph (25 km/h) in order for the TPMS to receive
this information.

FUEL REQUIREMENTS
2.4L Engine
These engines are designed to meet all
emissions regulations and provide excel-
lent fuel economy and performance when
using high quality unleaded “regular”
gasoline having an octane rating of 87.
The use of premium gasoline is not recommended, as it
will not provide any benefit over regular gasoline in
these engines.

STARTING AND OPERATING 519

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 experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle. Over 40 auto
manufacturers worldwide have issued and endorsed
consistent gasoline specifications (the Worldwide Fuel
Charter, WWFC) which define fuel properties necessary
to deliver enhanced emissions, performance, and dura-
bility for your vehicle. The manufacturer recommends
the use of gasoline that meet the WWFC specifications if
they are available.3.2L Engine
These engines are designed to meet all
emissions regulations and provide satisfac-
tory fuel economy and performance when
using high quality unleaded gasoline hav-
ing an octane range of 87 to 89. The manu-
facturer recommends the use of 89 octane premium
gasoline for optimum performance.
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 should be reported to
your dealer immediately. Engine damage resulting from
operating with a heavy spark knock may not be covered
by the new vehicle warranty.
520 STARTING AND OPERATING

E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing 10% ethanol (E10). Gasoline with higher
ethanol content may void the New Vehicle Limited
Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion. To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•
Drain the fuel tank (see your authorized dealer).
• Change the engine oil and oil filter.
• Disconnect and reconnect the battery to reset the
engine controller memory.
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT)
is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
522 STARTING AND OPERATING

CAUTION!(Continued)
•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 perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer.
NOTE: Intentional tampering with the emissions control
system 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.
