loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious accident. Do not drive a vehicle loaded to the
maximum capacity at continuous speeds above
75 mph (120 km/h).
Radial-Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial ply tires in sets of four. Never
combine them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs.
Compact Spare Tire
The compact spare is for temporary emergency use with
radial tires. It is engineered to be used on your style
vehicle only. Since this tire has limited tread life, the
original tire should be repaired (or replaced) and rein-
stalled at the first opportunity.

FUEL REQUIREMENTS
2.4L and 2.7L Engine
All engines are designed to meet all emis-
sion regulations and provide excellent 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.
3.5L Engine
The 3.5L engine is 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
for optimum performance. The use of premium gasoline
is not recommended, 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 experience these
300 STARTING AND OPERATING

symptoms, try another brand of gasoline (with the ap-
propriate octane rating for your engine) before consider-
ing 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) which
define fuel properties necessary to deliver enhanced
emissions, engine performance, and durability for your
vehicle. The manufacturer recommends the use of gaso-
lines that meet the WWFC specifications if they are
available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline.”
Reformulated gasolines contain oxygenates, and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.
CAUTION!
For vehicles equipped with a 2.4L or 3.5L engine, DO
NOT use gasoline containing Methanol or E85 Etha-
nol. Use of these blends may result in starting and
driveability problems and may damage critical fuel
system components.
5
STARTING AND OPERATING 301

NOTE:The2.7L engine is now rated for E85 Ethanol
use (EXCEPT CALIFORNIA EMISSION STATES). Only
vehicles with the E-85 fuel filler door label can operate on
E-85. Refer to “Flexible Fuel” in “Starting and Operating”
for further information.
Problems that result from using methanol/gasoline or
E85 Ethanol 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.
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
302 STARTING AND OPERATING

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
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 levels
higher than those allowed in the United States.
MMT is prohibited in Federal and California reformu-
lated 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
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 emission control system.(Continued)
5
STARTING AND OPERATING 303

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 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.
(Continued)
304 STARTING AND OPERATING

NOTE:The2.7L engine is now rated for E85 Ethanol
use (EXCEPT CALIFORNIA EMISSION STATES). Only
vehicles with the E85 fuel filler door label can operate on
E85.CAUTION!
Only vehicles with the E85 fuel filler door label can
operate on E85.
E85 Fuel CapE85 Badge
306 STARTING AND OPERATING

•Some additives used in regular gasoline are not fully
compatible with E85 and may form deposits in your
engine. To eliminate driveability issues that may be
caused by these deposits, a supplemental gasoline
additive, such as MOPARInjector Cleanup or
Techron may be used.
Selection Of Engine Oil For Flexible Fuel Vehicles
(E85) and Gasoline Vehicles
FFV vehicles operated on E85 require specially formu-
lated engine oils. These special requirements are included
in MOPAR engine oils, and in equivalent oils meeting
Chrysler Specification MS-6395. The manufacturer only
recommends engine oils that are API Certified and meet
the requirements of Material Standard MS-6395. MS-6395
contains additional requirements, developed during ex-
tensive fleet testing, to provide additional protection to
Chrysler Group LLC engines. Use MOPAR or an
equivalent oil meeting the specification MS-6395.
Starting
The characteristics of E85 fuel make it unsuitable for use
when ambient temperatures fall below 0°F (-18°C). In the
range of 0°F (-18°C) to 32°F (0°C), you may experience an
increase in the time it takes for your engine to start, and
a deterioration in driveability (sags and/or hesitations)
until the engine is fully warmed up.
NOTE: Use of the engine block heater (if equipped) is
beneficial for E85 startability when the ambient tempera-
ture is less than 32°F (0°C).
Cruising Range
Because E85 fuel contains less energy per gallon/liter
than gasoline, you will experience an increase in fuel
consumption. You can expect your miles per gallon
(mpg)/miles per liter and your driving range to decrease
by about 30%, compared to gasoline operation.
308 STARTING AND OPERATING

WARNING! (Continued)
•Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and doing so will cause the MIL to turn on.
•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.
•When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
Loose Filler Cap Message
If the vehicles diagnostic system determines that the fuel
filler cap in loose, improperly installed, or damaged, a
“gASCAP” message will be displayed in the instrument
cluster. Tighten the gas cap until a “clicking” sound is
heard. This is an indication that the gas cap is properly
tightened. Press the trip odometer reset button to turn off
the message. If the problem persists, the message will
appear the next time the vehicle is started. This might
indicate a damaged cap. If the problem is detected twice
in a row, the system will turn on the MIL. Resolving the
problem will turn the MIL off.
