SERVICING AND MAINTENANCE349
Synthetic Engine Oils
You may use synthetic engine oils provided the
recommended oil quality requirements are met,
and the recommended maintenance intervals
for oil and filter changes are followed.
Synthetic engine oils which do not have both the
engine oil certification mark and the correct SAE
viscosity grade number should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends
against the addition of any additives (other than
leak detection dyes) to the engine oil. Engine oil
is an engineered product and its performance
may be impaired by supplemental additives.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used
engine oil and oil filters from your vehicle. Used
oil and oil filters, indiscriminately discarded, can
present a problem to the environment. Contact
an authorized dealer, service station or govern -
mental agency for advice on how and where
used oil and oil filters can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced with a
new filter at every engine oil change.
Engine Oil Filter Selection
This manufacturer's engines have a full-flow
type disposable oil filter. Use a filter of this type
for replacement. The quality of replacement
filters varies considerably. Only high quality
filters should be used to ensure most efficient
service. Mopar engine oil filters are high quality
oil filters and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Plan” in this section
for the proper maintenance intervals.
NOTE:
Be sure to follow the “Severe Duty Conditions”
maintenance interval if applicable. Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner
filters varies considerably. Only high quality
filters should be used to ensure most efficient
service. Mopar engine air cleaner filters are a
high quality filter and are recommended.
Engine Air Cleaner Filter Inspection And
Replacement — Gas Engine
Inspect engine air cleaner filter for dirt and or
debris, if you find evidence of either dirt or
debris you should change your air cleaner filter.
WARNING!
The air induction system (air cleaner, hoses,
etc.) can provide a measure of protection in
the case of engine backfire. Do not remove
the air induction system (air cleaner, hoses,
etc.) unless such removal is necessary for
repair or maintenance. Make sure that no
one is near the engine compartment before
starting the vehicle with the air induction
system (air cleaner, hoses, etc.) removed.
Failure to do so can result in serious personal
injury.

Installing The Front Wipers

1. Lift the wiper arm off of the glass, until the
wiper arm is in the full up position.

2. Position the wiper blade under the hook on the tip of the wiper arm with the wiper
locking tab open.
3. Insert the receiver bracket on the wiper assembly into the hook on the tip of the arm
through the opening in the wiper blade
under the locking tab.
4. Slide the wiper blade up into the hook on the wiper arm until it is latched (engage -
ment will be accompanied by an audible
click). Fold down the latch release tab and
snap it into its locked position.
5. Gently lower the wiper blade onto the glass.
Exhaust System
The best protection against carbon monoxide
entry into the vehicle body is a properly main -
tained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the under -
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete exhaust system and adjacent body areas for
broken, damaged, deteriorated, or misposi
-
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, have the
exhaust system inspected each time the vehicle
is raised for lubrication or oil change. Replace
as required.
Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to ensure proper catalyst opera-
tion and prevent possible catalyst damage.
WARNING!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you. To avoid breathing CO, refer to
“Safety Tips” in “Safety” for further informa -
tion.
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.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as
an emissions control device and may seri -
ously reduce engine performance and
cause serious damage to the engine.
Damage to the catalytic converter can
result if your vehicle is not kept in proper
operating condition. In the event of engine
malfunction, particularly involving engine
misfire or other apparent loss of perfor -
mance, have your vehicle serviced
promptly. Continued operation of your
vehicle with a severe malfunction could
cause the converter to overheat, resulting
in possible damage to the converter and
vehicle.

SERVICING AND MAINTENANCE369
Use the following procedure to check the trans -
mission fluid level properly:

1. Monitor the transmission temperature using the instrument cluster display, and
operate the vehicle as required to reach
the normal operating temperature. If the
transmission is not functioning properly, or
the vehicle cannot be driven, see the NOTE
and CAUTION below about checking the
fluid level at colder temperatures.

2. Park the vehicle on level ground.
3. Run the engine at normal idle speed for at least 60 seconds, and leave the engine
running for the rest of this procedure.
4. Fully apply the parking brake, and press the brake pedal.
5. Place the gear selector momentarily into each gear position (allowing time for the
transmission to fully engage in each posi -
tion), ending with the transmission in PARK.
6. Remove the dipstick, wipe it clean and rein -
sert it until seated. 7. Remove the dipstick again and note the
fluid level on both sides. The fluid level
reading is only valid if there is a solid
coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full
of fluid if the actual level is at or above the
hole. The fluid level should be between the
“HOT” (upper) reference holes on the
dipstick at normal operating temperature. If
the fluid level is low, add fluid through the
dipstick tube to bring it to the proper level.
Do not overfill. Use ONLY the specified fluid
(refer to "Fluids And Lubricants" in “Tech -
nical Specifications” for fluid specifica -
tions). After adding any quantity of oil
through the dipstick tube, wait a minimum
of two minutes for the oil to fully drain into
the transmission before rechecking the
fluid level.
NOTE:
If it is necessary to check the transmission
below the operating temperature, the fluid level
should be between the two “COLD” (lower)
holes on the dipstick with the fluid at 60-70°F /
16-21°C. Only use the COLD region of the
dipstick as a rough reference when setting the
fluid level after a transmission service or fluid change. Re-check the fluid level, and adjust as
required, once the transmission reaches
normal operating temperature.
8. Reinsert the dipstick. Check for leaks.
Release the parking brake.
NOTE:
If it is necessary to check the transmission
below the operating temperature, the fluid level
should be between the two COLD (lower) holes
on the dipstick with the fluid at 68-86°F /
20-30°C. Only use the COLD region of the
dipstick as a rough reference when setting the
fluid level after a transmission service or fluid
change. Re-check the fluid level, and adjust as
required, once the transmission reaches
normal operating temperature.
CAUTION!
If the fluid temperature is below 50 °F (10
°C) it may not register on the dipstick. Do not
add fluid until the temperature is elevated
enough to produce an accurate reading. Run
the engine at idle, in PARK, to warm the fluid.

TECHNICAL SPECIFICATIONS403
Biodiesel Fuel Requirements
Chassis Cab Models
A maximum blend of 5% biodiesel meeting
ASTM specification D975 may be used with
your Cummins diesel engine. If operation with
biodiesel blends greater than 5% but not
greater than 20% (B6-B20) is desired, the truck
must first be reconfigured by an authorized
Ram dealer and the provisions in the following
section must be adhered to.
Pickup Models And Chassis Cab Models
Ordered With B20 Option
Your vehicle has been validated and approved
for the use of biodiesel in blends up to 20%
(B20) provided that you comply with the require -
ments outlined below. It is important that you
understand and comply with these require -
ments. Failure to comply with Oil Change
requirements for vehicles operating on
biodiesel blends up to B20 will result in prema -
ture engine wear. Such wear is not covered by
the New Vehicle Limited Warranty. 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 limita-
tions which require that you understand and
adhere to the following requirements if you use
blends of biodiesel greater then 5% but not
greater than 20% (B6-B20). There are no
unique restrictions for the use of B5. 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.Fuel Quality — Must Comply With ASTM
Standards
The quality of biodiesel fuel may vary widely.
Only fuel produced by a BQ9000 supplier to the
following specifications may be blended to
meet biodiesel blend (B6–B20) fuel meeting
ASTM specification D-7467:
Pretrodiesel fuel meeting ASTM specification
D-975 and biodiesel fuel (B100) meeting
ASTM specification D-6751.
Fuel Oxidation Stability — Must Use Fuel
Within Six Months Of Manufacture
Biodiesel fuel has poor oxidation stability which
can result in long term storage problems. Fuel
produced to approved ASTM standards, if
stored properly, provides for protection against
fuel oxidation for up to six months.
Fuel Water Separation — Must Use Mopar/
Cummins Approved Fuel Filter Elements
You must use Mopar/Cummins approved fuel
filter elements in both your engine mounted
filter and frame mounted filter.
Biodiesel fuel has a natural affinity to water and
water accelerates microbial growth. Your
Mopar/Cummins filtration system is designed
to provide adequate fuel water separation capa-
bilities.
Bio-Diesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient
temperatures, which may pose problems for
both storage and operation. Precautions can be
necessary at low ambient temperatures, such
as storing the fuel in a heated building or a
heated storage tank, or using cold temperature
additives.
