4. Re-install the access cover.IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
NOTE:
There are steps that you can take to slow down
an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the
heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.

410SERVICING AND MAINTENANCE
If the “Water In Fuel Indicator Light” comes on
and a single chime is heard while you are
driving, or with the ignition switch in the ON
position, there may be a problem with your
water separator wiring or sensor. See an
authorized dealer for service.

Upon proper draining of the water from both fuel
filters, the “Water In Fuel Indicator Light” will
remain illuminated for approximately 10 seconds.
If the water was drained while the engine was
running, the “Water In Fuel Indicator Light” may
remain on for approximately three minutes.

NOTE:
Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately
discarded, can present a problem to the envi -
ronment. Contact an authorized dealer, service
station, or government agency for advice on
recycling programs and for where used fluids
and filters can be properly disposed of in your
area. Drain the fuel/water separator filters when the
“Water In Fuel Indicator Light” is ON. Within
10 minutes of vehicle shutdown, turn the
engine mounted filter drain valve (located on
the side of the filter assembly)
counterclockwise 1/4 turn, and turn the under
body mounted filter drain valve (located on the
bottom of the filter assembly) counterclockwise
wise 1 full turn. Then turn the ignition switch to
the ON position, and allow any accumulated
water to drain. Leave the drain valve open until
all water and contaminants have been
removed. When clean fuel is visible, close the
drain valve following these guidelines:

1. Rotate the drain clockwise to close until
you feel resistance from the internal seal.

2. Continue turning the drain 1/2 of a turn to properly compress the seal.
NOTE:
Over-compression of the seal due to over-tight -
ening of the drain will damage the seal, cause a
leak, and require the entire sensor to be
replaced.
3. Turn the ignition switch to OFF. The sensor drain should not be over-tightened
during normal service operations to avoid
internal damage and future fuel leaks. The
drain should be closed and secured without the
use of tools.
If more than a couple ounces/milliliters of fuel
have been drained, follow the directions for
“Priming If The Engine Has Run Out Of Fuel.”

the Diesel Particulate Filter, the engine idle
speed will return to normal when the brake
pedal is applied. A small change in engine tone
or a slight change in engine performance while
accelerating may also be noticeable at speeds
below 20 mph (32 km/h). This operating mode
may last for up to an hour of idle time, or around
20 minutes of driving time.
Additionally, your vehicle has the ability to alert
you to additional maintenance required on your
truck or engine.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.DIESEL EXHAUST FLUID
Diesel Exhaust Fluid (DEF) sometimes known
simply by the name of its active component,
UREA—is a key component of selective catalytic
reduction (SCR) systems, which help diesel
vehicles meet stringent emission regulations.
DEF is a liquid reducing agent that reacts with
engine exhaust in the presence of a catalyst to
convert smog-forming nitrogen oxides (NOx)
into harmless nitrogen and water vapor.
Refer to “Fluids And Lubricants” in “Technical
Specification” for further information.
You can receive assistance in locating DEF in
the United States by calling 866-RAM-INFO
(866-726-4636). In Canada call
1–800–465–2001 (English) or
1–800–387–9983 (French)
You can receive assistance in locating DEF by
contacting an authorized dealer.
BODY LUBRICATION
Locks and all body pivot points, including such
items as seat tracks, door hinge pivot points
and rollers, liftgate, tailgate, decklid, sliding
doors and hood hinges, should be lubricated
periodically with a lithium based grease, such as Mopar Spray White Lube to ensure quiet,
easy operation and to protect against rust and
wear. Prior to the application of any lubricant,
the parts concerned should be wiped clean to
remove dust and grit; after lubricating, excess
oil and grease should be removed. Particular
attention should also be given to hood latching
components to ensure proper function. When
performing other underhood services, the hood
latch, release mechanism and safety catch
should be cleaned and lubricated.
The external lock cylinders should be lubricated
twice a year, preferably in the Autumn and
Spring. Apply a small amount of a high quality
lubricant, such as Mopar Lock Cylinder
Lubricant directly into the lock cylinder.
WINDSHIELD WIPER BLADES
Clean the rubber edges of the wiper blades and
the windshield periodically with a sponge or soft
cloth and a mild nonabrasive cleaner. This will
remove accumulations of salt or road film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using the
wipers to remove salt or dirt from a dry
windshield.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do not
park or operate your vehicle in areas where
your exhaust system can contact anything
that can burn.

SERVICING AND MAINTENANCE415
Avoid using the wiper blades to remove frost or
ice from the windshield. Keep the blade rubber
out of contact with petroleum products such as
engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies
depending on geographical area and frequency
of use. Poor performance of blades may be
present with chattering, marks, water lines or
wet spots. If any of these conditions are
present, clean the wiper blades or replace as
necessary.
The wiper blades and wiper arms should be
inspected periodically, not just when wiper
performance problems are experienced. This
inspection should include the following points:
Wear or uneven edges
Foreign material
Hardening or cracking
Deformation or fatigue
