G/T AIR FILTER MAINTENANCE
Clean Engine Air Filter
The scheduled air filter cleaning interval is 30,
000 miles (48,280 km), or if in a dusty
environment the engine air filter should be
checked periodically to ensure optimal air flow.

1. Spray the air filter with the recommended
Mopar® air filter cleaner or apply mild
dishwashing detergent and water and let sit
for at least 10 minutes to loosen dir before
rinsing.

NOTE:Never use strong detergents, high pressure, or
gasoline on the air filter.
2. Rinse the air filter with cool low-pressure water applied from the inside (clean side) out in
order to flush the dirt out of the filter. Continue
to rinse the filter until all traces of the cleaner
have been removed.
NOTE:It may be necessary to repeat steps 1 and 2 if the
air filter is not completely clean.
3. After rinsing the air filter, gently shake off the excess water and allow air filter to dry
naturally.
NOTE:Do not use forced air pressure as it may damage
the filtering capabilities of the filter’s microfibers
and also void its warranty.
DRAINING FUEL/WATER SEPARATOR
F
ILTER — DIESEL ENGINE
The fuel/water separator filter housing is located
inside the frame rail, behind the left front wheel.
The best access to this water drain valve is from
under the vehicle.
If water is detected in the water separator while the
engine is running, or while the ignition switch is in
the ON/RUN position, the Water In Fuel Indicator
Light will illuminate and an audible chime will be
heard. At this point, you should stop the engine
and drain the water from the filter housing.
Fuel Filter Assembly

If the Water In Fuel Indicator Light comes on and a
single chime is heard while you are driving, or with
the ignition in the ON position, there may be a
problem with your water separator wiring or
sensor. See an authorized dealer for service.
CAUTION!
Do not drain the fuel/water separator filter
when the engine is running.
Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appropriate
container.
1 — Water In Fuel Drain Valve
CAUTION!
If the Water In Fuel Indicator Light remains on,
DO NOT START the engine before you drain water
from the fuel filter to avoid engine damage.

454SERVICING AND MAINTENANCE
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
Driving style
Tire pressure - Improper cold tire inflation pres -
sures can cause uneven wear patterns to
develop across the tire tread. These abnormal
wear patterns will reduce tread life, resulting in
the need for earlier tire replacement
Distance driven
Performance tires, tires with a speed rating of V
or higher, and Summer tires typically have a
reduced tread life. Rotation of these tires per
the vehicle scheduled maintenance is highly
recommended
NOTE:Wheel Valve Stem must be replaced as well when
installing new tires due to wear and tear in existing
tires. Keep dismounted tires in a cool, dry place with as
little exposure to light as possible. Protect tires
from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected
regularly for wear and correct cold tire inflation
pressures. The manufacturer strongly
recommends that you use tires equivalent to the
originals in size, quality and performance when
replacement is needed Ú
page 453. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size designation
of your tire. The Load Index and Speed Symbol for
your tire will be found on the original equipment
tire sidewall.
For more information relating to the Load Index
and Speed Symbol of a tire Ú page 445.
It is recommended to replace the two front tires or
two rear tires as a pair. Replacing just one tire can
seriously affect your vehicle’s handling. If you ever
replace a wheel, make sure that the wheel’s
specifications match those of the original wheels.
It is recommended you contact an authorized tire
dealer or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent replacement
tires may adversely affect the safety, handling, and
ride of your vehicle.
WARNING!
Tires and the spare tire should be replaced after
six years, regardless of the remaining tread.
Failure to follow this warning can result in
sudden tire failure. You could lose control and
have a collision resulting in serious injury or
death.
WARNING!
Do not use a tire, wheel size, load rating, or
speed rating other than that specified for your
vehicle. Some combinations of unapproved
tires and wheels may change suspension
dimensions and performance characteristics,
resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpre -
dictable handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire and
wheel sizes with load ratings approved for
your vehicle.
Never use a tire with a smaller load index or
capacity, other than what was originally
equipped on your vehicle. Using a tire with a
smaller load index could result in tire over -
loading and failure. You could lose control and
have a collision.
Failure to equip your vehicle with tires having
adequate speed capability can result in
sudden tire failure and loss of vehicle control.

470TECHNICAL SPECIFICATIONS
Diesel fuel is seldom completely free of water. To
prevent fuel system trouble, drain the
accumulated water from the fuel/water separator
filter using the fuel/water separator drain provided
on the fuel filter housing. If you buy good quality
fuel and follow the cold weather advice above, fuel
conditioners should not be required in your vehicle.
If available in your area, a high cetane “premium”
diesel fuel may offer improved cold-starting and
warm-up performance.
DIESEL FUEL SPECIFICATIONS
This diesel engine has been developed to take
advantage of the high energy content and
generally lower cost Number 2 Ultra Low Sulfur
diesel fuel or Number 2 Ultra Low Sulfur Climatized
diesel fuels.
NOTE:
If you accidentally fill the fuel tank with gasoline
or DEF on your diesel vehicle, do not start the
engine. Damage to the engine and fuel system
could occur. Please call an authorized dealer for
service.
A maximum blend of 5% biodiesel meeting
ASTM specification D-975 may be used with
your diesel engine without any adjustments to
regular service schedules.
Commercially available fuel additives are not
necessary for the proper operation of your
diesel engine.
Number 1 Ultra Low Sulfur diesel fuel should
only be used where extended arctic conditions
(-10°F or -23°C) exist.
BIODIESEL FUEL REQUIREMENTS
A maximum blend of 5% biodiesel meeting ASTM
specification D975 is recommended for use with
your diesel engine. If frequent operation with
Biodiesel blends that are between 6% and 20%
(B6–B20) is desired, the maintenance schedule is
subject to shorter intervals.
The oil and filter change along with fuel filter
replacement is subject to shorter intervals when
operating your engine on biodiesel greater than
5%. Do not use biodiesel greater than 20%. For regular use of biodiesel blends between 6%
and 20% (B6–B20) it is important that you
understand and comply with these requirements.
For further direction Ú
page 402.
Biodiesel is a fuel produced from renewable
resources typically derived from animal fat,
rapeseed oil (Rapeseed Methyl Ester (RME) base),
or soybean oil (Soy Methyl Ester (SME or SOME)
base).
Biodiesel fuel has inherent limitations which
require that you understand and adhere to the
following requirements if you use blends of
Biodiesel between 6% and 20% (B6–B20). There
are no unique restrictions for the use of B5.
CAUTION!
If the Water in Fuel Indicator Light remains on,
DO NOT START engine before you drain the water
from the fuel filter(s) to avoid engine damage
Ú page 412.
CAUTION!
Failure to comply with Oil Change requirements
for vehicles operating on biodiesel blends
between 6% and 20% (B6–B20) will result in
premature engine wear. Such wear is not
covered by the New Vehicle Limited Warranty.
CAUTION!
Use of blends greater than 20% is not approved.
Use of blends greater than 20% can result in
engine damage. Such damage is not covered by
the New Vehicle Limited Warranty.
