SERVICING AND MAINTENANCE399
CHECKING OIL LEVEL — GAS ENGINE

To ensure proper lubrication of your vehicle's
engine, the engine oil must be maintained at the
correct level. Check the oil level at regular
intervals, such as every fuel stop. The best time
to check the engine oil level is about five minutes
after a fully warmed up engine is shut off.

Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Always maintain the oil level within
the SAFE zone on the dipstick. Adding one quart
of oil when the reading is at the bottom of the
SAFE zone will result in a reading at the top of
the safe zone on these engines.
CHECKING OIL LEVEL — DIESEL ENGINE

To ensure proper lubrication of your vehicle's
engine, the engine oil must be maintained at
the correct level. Check the oil level at regular
intervals. The best time to check the oil level is
before starting the engine after it has been parked overnight. When checking oil after
operating the engine, first ensure the engine is
at full operating temperature, then wait for
30 minutes after engine shutdown to check
the oil.

Engine Oil Dipstick

Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Add oil only when the level on the
dipstick is below the “ADD” mark. The total
capacity from the ADD mark to the Full mark is
2 qts (1.9L). Never operate the engine with oil level below
the “ADD” mark or above the upper “SAFE”
mark.
ADDING WASHER FLUID
The fluid reservoir is located under the hood
and should be checked for fluid level at regular
intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze).
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe the wiper blades clean. This will
help blade performance.
To prevent freeze-up of your windshield washer
system in cold weather, select a solution or
mixture that meets or exceeds the temperature
range of your climate. This rating information
can be found on most washer fluid containers.
CAUTION!
Overfilling or underfilling will cause oil
aeration or loss of oil pressure. This could
damage your engine.
1 — ADD Range
2 — Full Mark
3 — SAFE Range
CAUTION!
Overfilling or underfilling the crankcase will
cause oil aeration or loss of oil pressure. This
could damage your engine.

400SERVICING AND MAINTENANCE
After the engine has warmed up, operate the
defroster for a few minutes to reduce the
possibility of smearing or freezing the fluid on
the cold windshield. Windshield washer solution
used with water as directed on the container,
aids cleaning action, reduces the freezing point
to avoid line clogging, and is not harmful to
paint or trim.
MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a
maintenance-free battery. You will never have
to add water, nor is periodic maintenance
required.
PRESSURE WASHING
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes
or on skin, flush the area immediately with
large amounts of water. Refer to “Jump
Starting Procedure” in “In Case Of Emer -
gency” for further information.
Battery gas is flammable and explosive.
Keep flame or sparks away from the
battery. Do not use a booster battery or any
other booster source with an output greater
than 12 Volts. Do not allow cable clamps to
touch each other.
Battery posts, terminals, and related acces -
sories contain lead and lead compounds.
Wash hands after handling.
CAUTION!
It is essential when replacing the cables on
the battery that the positive cable is
attached to the positive post and the nega -
tive cable is attached to the negative post.
Battery posts are marked positive (+) and
negative (-) and are identified on the battery
case. Cable clamps should be tight on the
terminal posts and free of corrosion.
If a “fast charger” is used while the battery
is in the vehicle, disconnect both vehicle
battery cables before connecting the
charger to the battery. Do not use a “fast
charger” to provide starting voltage.
CAUTION!
Cleaning the engine compartment with a high
pressure washer is not recommended.
Precautions have been taken to safeguard all
parts and connections however, the
pressures generated by these machines is
such that complete protection against water
ingress cannot be guaranteed.

414SERVICING AND MAINTENANCE
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.
