•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
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without 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
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
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
conditions and they would result in additional cost.
Therefore, you should not have to add anything to the
fuel.

STARTING AND OPERATING 391
MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate in the instrument clus-
ter. This means that service is required for your vehicle.
Operating conditions such as frequent short-trips, trailer
tow and extremely hot or cold ambient temperatures will
influence when the “Change Oil” or “Oil Change Re-
quired” message is displayed. Severe Operating Condi-
tions can cause the change oil message to illuminate as
early as 3,500 miles (5,600 km) since last reset. Have your
vehicle serviced as soon as possible, within the next 500
miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)/Driver Information Display
(DID)” in “Getting To Know Your Instrument Panel” for
further information.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Severe Duty All Models
Change Engine Oil at 4000 miles (6,500 km) if the vehicle
is operated in a dusty and off road environment. This
type of vehicle use is considered Severe Duty
NOTE:The Oil Change Indicator will not illuminate
under these conditions.
