E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s 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 corrosionTo 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
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 emission system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content

Towing Tips
Before setting out on a trip, practice turning, stopping,
and backing the trailer in an area located away from
heavy traffic.
Automatic Transmission
The “DRIVE” range can be selected when towing. How-
ever, if frequent shifting occurs while in this range,
activate the TOW/HAUL feature. Refer to “Automatic
Transmission” in “Starting and Operating” for further
information.
NOTE:Using the TOW/HAUL feature while operating
the vehicle under heavy operating conditions will im-
prove performance and extend transmission life by re-
ducing excessive shifting and heat build up. This action
will also provide better engine braking.
If you REGULARLY tow a trailer for more than 45 min-
utes of continuous operation, then change the automatic
transmission fluid and filter according to the interval specified for “police, taxi, fleet, or frequent trailer tow-
ing.” Refer to “Maintenance Schedule” for the proper
maintenance intervals.
TOW/HAUL
To reduce potential for automatic transmission overheat-
ing, press the TOW/HAUL button when driving in hilly
areas or select the
2range on more severe grades. Refer
to “Automatic Transmission” in “Starting and Operat-
ing” for further information.
Electronic Speed Control – If Equipped

Do not use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.

CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is
not covered by the New Vehicle Limited Warranty.
Engine Oil Viscosity
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. The engine oil filler
cap also shows the recommended engine oil viscosity for
your engine. For information on engine oil filler cap
location, refer to “Engine Compartment” in “Maintaining
Your Vehicle” for further information.
Lubricants which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Materials Added To Engine Oil
Do not add any supplemental additives, other than leak
detection dyes, to your engine oil. Engine oil is an
engineered product and its performance may be im-
paired by supplemental additives.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station, or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
