AIR CONDITIONER MAINTENANCE
For best possible performance, your air conditioner
should be checked and serviced by an authorized
dealer at the start of each warm season. This
service should include cleaning of the condenser
fins and a performance test. Drive belt tension
should also be checked at this time.
Refrigerant Recovery And Recycling
R-134a — If Equipped
R-134a Air Conditioning Refrigerant is a Hydrofluo -
rocarbon (HFC) that is an ozone-friendly
substance. The manufacturer recommends that
air conditioning service be performed by an
authorized dealer or other service facilities using
recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C system PAG
compressor oil and refrigerants.
Refrigerant Recovery And Recycling
R-1234yf — If Equipped
R-1234yf Air Conditioning Refrigerant is a Hydroflu -
oroolefin (HFO) that is endorsed by the
Environmental Protection Agency and is an
ozone-friendly substance with a low
global-warming potential. The manufacturer
recommends that air conditioning service be
performed by an authorized dealer using recovery
and recycling equipment.
NOTE:Use only manufacturer approved A/C system PAG
compressor oil, and refrigerants.

WARNING!

Use only refrigerants and compressor lubri
-
cants approved by the manufacturer for your
air conditioning system. Some unapproved
refrigerants are flammable and can explode,
injuring you. Other unapproved refrigerants or
lubricants can cause the system to fail,
requiring costly repairs. Refer to Warranty Infor -
mation Book, for further warranty information.
The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring lines
to be disconnected should be done by an expe -
rienced technician.

CAUTION!

Do not use chemical flushes in your air condition -
ing system as the chemicals can damage your air
conditioning components. Such damage is not
covered by the New Vehicle Limited Warranty.

Cabin Air Filter Replacement
For the proper maintenance intervals Úpage 329.
The cabin air filter is located in the fresh air inlet
behind the glove compartment. Perform the
following procedure to replace the filter:

1. Open the glove compartment and remove all contents.

2. With the glove compartment door open, remove the glove compartment tension tether
and tether clip by sliding the clip toward the
face of the glove compartment door. Lift the
clip out of glove compartment door and
release into dash panel.
Right Side Of Glove Compartment

3. There are travel stops on both sides of the glove compartment. Push inward on right side
of the glove compartment travel stop to
disengage the stop. Then pull the right of the
glove compartment outward (away from the
hinge) to disengaging the right side of the
compartment from the hinge. Continue by
removing the left side from the hinge by slightly
lowering the compartment while pulling
outward until it is completely disengaged from
the hinge.

WARNING!
Do not attempt to inspect an accessory drive
belt with vehicle running.
When working near the radiator cooling fan,
disconnect the fan motor lead. The fan is
temperature controlled and can start at any
time regardless of ignition mode. You could be
injured by the moving fan blades.
You can be badly injured working on or around
a motor vehicle. Only do service work for which
you have the knowledge and the proper equip -
ment. If you have any doubt about your ability
to perform a service job, take your vehicle to a
competent mechanic.

8. Install new o-ring back into ring groove on the filter housing and lubricate with clean engine
oil.
NOTE:Water In Fuel (WIF) sensor is re-usable. Service kit
comes with new o-ring for filter canister and WIF
sensor.
PRIMING IF THE ENGINE HAS RUN OUT
O
F FUEL

1. Add a substantial amount of fuel to the tank,
approximately 2 to 5 gal (8L to 19L).

2. Three priming cycles must be completed. Turn ignition to the RUN position and wait approxi -
mately 30 seconds. This will activate the in tank
fuel pump. Turn the ignition switch to the off
position, and leave off for at least 30 seconds.
Repeat this procedure three times before
cranking the engine.
3. Start the engine using the “Normal Starting”
procedure Ú page 108.
4. Once the engine starts, allow the engine to idle for a minimum of 30 seconds.
NOTE:The engine may run rough until the air is forced
from all the fuel lines.
NOTE:
A maximum blend of 5% biodiesel, meeting
ASTM specification D-975 may be used with
your Cummins® diesel engine.
A maximum blend of 20% biodiesel, meeting
ASTM specification D-7467 may be used with
your Cummins® diesel engine.
Use of biodiesel mixture in excess of 20% can
negatively impact the fuel filter's ability to sepa -
rate water from the fuel, resulting in high pres -
sure fuel system corrosion or damage.
Ethanol blends are not recommended or
approved for use with your Cummins® diesel
engine.
In addition, commercially available fuel addi -
tives are not necessary for the proper operation
of your Cummins® diesel engine.
INTERVENTION REGENERATION
S
TRATEGY — MESSAGE PROCESS FLOW
The Cummins® diesel engine meets all
Environmental Protection Agency (EPA) Heavy Duty
Diesel Engine Emissions Standards, resulting in
one of the lowest emitting diesel engines ever
produced.
To achieve these emissions standards, your
vehicle is equipped with a state-of-the-art engine
and exhaust system. The engine and exhaust
after-treatment system work together to achieve
WARNING!
Do not open the high pressure fuel system with
the engine running. Engine operation causes
high fuel pressure. High pressure fuel spray can
cause serious injury or death.
CAUTION!
Do not engage the starter motor for more than
15 seconds at a time. Allow two minutes
between the cranking intervals.
WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain
conditions and be hazardous or explosive when
mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or gasoline,
the use of these fuels can cause damage to the
fuel system.

362SERVICING AND MAINTENANCE
Exhaust System
Inspect the entire exhaust system for leaks and
damaged parts. Devices such as hangers, clamps,
and U-bolts should be tight and in good condition.
Damaged components, burned or blown out
mufflers, burned or rusted out exhaust pipes
should be replaced according to the procedures
and specifications outlined in the appropriate
service manual.
Air Cleaner Assembly
Inspect air cleaner housing for proper assembly
and fit. Make certain that the air cleaner is properly
positioned and that the cover is tight. Check all
hoses leading to the air cleaner for tightness. The
air filter element must also be clean and serviced
according to the instructions outlined in the
Scheduled Maintenance section of this manual.
