440 STARTING AND OPERATING

WARNING!
Never attempt to climb a hill at an angle or turn
around on a steep grade. Driving across an incline
increases the risk of a roll over, which may result in
severe injury or death.
• Driving Down Hill – Before driving down a steep hill
you need to determine if it is too steep for a safe
descent. What is the surface traction? Is the grade too
steep to maintain a slow controlled descent? Are there
obstacles? Is it a straight descent? Is there plenty of
distance at the base of the hill to regain control if the
vehicle descends too fast? If you feel confident in your
ability to proceed then make sure you are in 4L (Low
Range) with the transmission in first gear (manually
select first gear on automatic transmissions) and pro-
ceed with caution. Allow engine braking to control the
descent and apply your brakes if necessary, but do not
allow the tires to lock.
WARNING!
Do not descend a steep grade in NEUTRAL. Use
vehicle brakes in conjunction with engine braking.
Descending a grade too fast could cause you to lose
control and be seriously injured or killed.
• Driving Across An Incline – If at all possible avoid
driving across an incline. If it is necessary, know your
vehicle’s abilities. Driving across an incline places
more weight on the down hill wheels, which increases
the possibilities of a down hill slide or rollover. Make
sure the surface has good traction with firm and stable
soils. If possible transverse the incline at an angle
heading slightly up or down.

WARNING!(Continued)
distances. Therefore, after driving through stand-
ing water, drive slowly and lightly press on the
brake pedal several times to dry the brakes.
• Failure to follow these warnings may result in
injuries that are serious or fatal to you, your pas-
sengers, and others around you.
CAUTION!
• Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
• Determine the condition of the road or the path
that is under water and if there are any obstacles in
the way before driving through the standing water.
(Continued)
CAUTION! (Continued)
•Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.
• Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always
inspect your vehicle’s fluids (i.e., engine oil, trans-
mission, axle, etc.) for signs of contamination (i.e.,
fluid that is milky or foamy in appearance) after
driving through standing water. Do not continue to
operate the vehicle if any fluid appears contami-
nated, as this may result in further damage. Such
damage is not covered by the New Vehicle Limited
Warranty.
• Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
548 STARTING AND OPERATING

Fuel Requirements
Your vehicle will operate on both unleaded gasoline with
any octane rating, or solely E-85 fuel, or any mixture of
these fuels. For best results, avoid refueling pattern
alternating between E-85 and unleaded gasoline.
When switching fuel types:
•Add 5 gallons (19 liters) or more when refueling.
• You operate the vehicle immediately after refueling for
a period of at least 5 minutes.
Observing these precautions will avoid possible hard
starting and/or significant deterioration in driveability
during warm up. NOTE:
•
When the ambient temperature is above 90° F (32° C),
you may experience hard starting and rough idle
following start up even if the above recommendations
are followed.
• Some additives used in regular gasoline are not fully
compatible with E-85 and may form deposits in your
engine. To eliminate driveability issues that may be
caused by these deposits, a supplemental gasoline
additive, such as MOPAR® Injector Cleanup or
Techron may be used.
Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) And Gasoline Vehicles
FFV vehicles operated on E-85 require specially formu-
lated engine oils. These special requirements are included
in MOPAR® engine oils, and in equivalent oils meeting
FCA US Material Standard MS-6395. It is recommended
634 STARTING AND OPERATING

that engine oils that are API Certified and meet the
requirements of Material Standard MS-6395 be used.
MS-6395 contains additional requirements, developed
during extensive fleet testing, to provide additional pro-
tection to FCA US LLC engines.
Starting
The characteristics of E-85 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), an increase in the time
it takes for your engine to start may be experienced, and
a deterioration in driveability (sags and/or hesitations)
until the engine is fully warmed up. These issues may be
improved with the use of seasonally adjusted E-85 fuel.
NOTE:Use of the engine block heater (if equipped) may
improve engine start time when using E-85 fuel when the
ambient temperature is less than 32°F (0°C).
Cruising Range
Because E-85 fuel contains less energy per gallon/liter
than gasoline, an increase in fuel consumption will be
experienced. The miles per gallon (mpg)/kilometers per
liter and the driving range will decrease by approxi-
mately 30%, compared to gasoline operation.
Replacement Parts
All fuel and engine components in your Flexible Fuel
Vehicle (FFV) are designed to be compatible with ethanol.
Ethanol compatible service components are required.
CAUTION!
Replacing fuel system components with non-ethanol
compatible components can damage your vehicle.
