Telltale Light” will remain ON and a chime will sound. In
addition, the graphic in the EVIC will still display a
flashing pressure value.
3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “TPM Telltale Light” will flash on
and off for 75 seconds and then remain on solid. In
addition, the EVIC will display aSERVICE TPM SYS-
TEM message for a minimum of five seconds and then
display dashes (- -) in place of the pressure value.
4. For each subsequent ignition switch cycle, a chime will
sound, the “TPM Telltale Light” will flash on and off for
75 seconds and then remain on solid, and the EVIC will
display a SERVICE TPM SYSTEM message for a mini-
mum of five seconds and then display dashes (- -) in
place of the pressure value. 5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
“TPM 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 mph (24 km/h) in order for the TPMS to receive this
information.

FUEL REQUIREMENTS
3.6L And 5.7L Engine
(With Automatic Transmission)
The 3.6L and 5.7L engine (with automatic
transmission) is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and performance when us-
ing high-quality unleaded gasoline having
an octane range of 87 to 89. The manufac-
turer recommends the use of 89 octane for optimum
performance. The use of premium gasoline is not recom-
mended, as it will not provide any benefit over regular
gasoline in these engines. 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 World
Wide Fuel Charter, WWFC) which define fuel properties
necessary to deliver enhanced emissions, performance,
and durability for your vehicle. The manufacturer recom-
mends the use of gasolines that meet the WWFC speci-
fications, if they are available.5

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 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
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. It is even more important to
look for gasoline without MMT in Canada, because MMT
5
STARTING AND OPERATING 329

can be used at levels higher than those allowed in the
United States. MMT is prohibited in Federal and Califor-
nia 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.
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 perfor-
mance and damage the emissions control system.(Continued)
CAUTION! (Continued)
•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 authorized 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 concentra-
tions 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 the emissions con-
trol system can result in civil penalties being assessed
against you.
330 STARTING AND OPERATING

CAUTION!
•Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap (gas cap).
•A poorly fitting gas cap could let impurities into
the fuel system.
•A poorly fitting gas cap may cause the “Malfunc-
tion Indicator Light (MIL)” to turn on.
•To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. When the fuel
nozzle “clicks” or shuts off, the fuel tank is full.
WARNING!
•Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank is being filled.
•Never add fuel to the vehicle when the engine is
running.
•A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
NOTE:
•Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The MIL in the instrument cluster may turn
on if the gas cap is not secured properly. Make sure
that the gas cap is tightened each time the vehicle is
refueled.

Towing Requirements – Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.

specified for “police, taxi, fleet, or frequent trailer tow-
ing.” Refer to “Maintenance Schedule” for the proper
maintenance intervals.
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.
AutoStick

By using the AutoStick mode and selecting a specific
gear range, frequent shifting can be avoided. The
highest gear range should be selected that allows for
adequate performance. For example, choose “4” if the
desired speed can be maintained. Choose “3” or “2” if
needed to maintain the desired speed.
Extended driving at high RPM should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at
high RPM. Return to a higher gear range or vehicle
speed when road conditions and RPM level allows.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods, shift the transmission
into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
