2017 Ram 3500 Chassis Cab air filter

Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Use of the Air Recirculation mode
during Winter months is not recommended, because it may
cause window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service (i.e.,
vacation) for two weeks or more, run the air conditioning
system at idle for about five minutes, in fresh air with the
blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy
and/or humid weather. To clear the windows, select
Defrost or Mix mode and increase the front blower speed.
Do not use the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
winter months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The climate control system filters out dust and pollen from
the air. Contact your authorized dealer to service your
cabin air filter, and to have it replaced when needed.

Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
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 ve-
hicle with the air induction system (air cleaner, hoses,
etc.) removed. Failure to do so can result in serious
personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters varies
considerably. Only high quality filters should be used to
assure most efficient service. Mopar engine air cleaner
filters are a high quality filter and are recommended.
Engine Air Cleaner Filter Inspection and
Replacement
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.

Refrigerant Recovery And Recycling R1234yf — If
Equipped
R-1234yf Air Conditioning Refrigerant is a hydrofluoole-
fine HFO that is an ozone-saving product with a low GWP
(Global Warming Potential). However, the manufacturer
recommends that air conditioning service be performed by
authorized dealer or other service facilities using recovery
and recycling equipment.
NOTE:Use only manufacturer approved A/C system
PAG compressor oil and refrigerants.
Cabin Filter Replacement (A/C Air Filter)
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
WARNING!
Do not remove the cabin air filter while the vehicle is
running, or while the ignition is in the ACC or ON/
RUN mode. With the cabin air filter removed and the
blower operating, the blower can contact hands and
may propel dirt and debris into your eyes, resulting in
personal injury. 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 compart-
ment door. Lift the clip out of glove compartment door
and release into dash panel.

Fluid Level Check
This fluid level can be checked by removing the filler plug.
The fluid level should be to the bottom edge of the filler
plug hole with the vehicle in a level position.
Automatic Transmission — If Equipped
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer ’s specified transmission fluid. Refer
to “Fluids, Lubricants, And Genuine Parts” in this section
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid. No chemical flushes should be used in any
transmission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder, and will require more frequent fluid and
filter changes. Refer to “Fluids, Lubricants, And Genu-
ine Parts” in this section for fluid specifications.
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis-
sion Fluid (ATF) is an engineered product and its perfor-
mance may be impaired by supplemental additives. There-
fore, do not add any fluid additives to the transmission.
Avoid using transmission sealers as they may adversely
affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.
Fluid Level Check
Check the fluid level when the engine is fully warmed up
and the transmission fluid is at normal operating tempera-
ture. Driving with an improper fluid level will greatly
reduce the life of the transmission and of the fluid. Check
the fluid level whenever the vehicle is serviced.
