2015 Ram 1500 air conditioning

Air Conditioning
Turn off temporarily.
Air Suspension System
To aid in attaching/detaching the trailer from the vehicle,
the air suspension system can be used. Refer to “Air
Suspension System” in “Starting And Operating” for
further information.
NOTE:The vehicle must remain in the engine running
position while attaching a trailer for proper leveling of
the air suspension system.
SNOWPLOW
1500 Models Only
NOTE:Do not use this model vehicle for snowplow
applications.
WARNING!
Snowplows and other aftermarket equipment should
not be added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in
the front end structure. The airbags could deploy
unexpectedly or could fail to deploy during a colli-
sion resulting in serious injury or death.
CAUTION!
Using this vehicle for snowplow applications can
cause damage to the vehicle.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in a collision.

STARTING AND OPERATING 669

CAUTION!(Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure 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.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.7

CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condi-
tioning components. Such damage is not covered by
the New Vehicle Limited Warranty.
Refrigerant Recovery And Recycling R134a — If
Equipped
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, 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.
Refrigerant Recovery And Recycling HFO 1234yf —
If Equipped
HFO 1234yf Air Conditioning Refrigerant is a hydro-
fluorocarbon (HFC) that is endorsed by the Environmen-
tal Protection Agency and is an ozone-saving product
with a low GWP (Global Warming Potential). However,
the manufacturer recommends that air conditioning ser-
vice 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.
Front Driveshaft Lubrication — 2500/3500
(Four-Wheel Drive Models Only)
Lubricate the front driveshaft grease fitting at each oil
change. Refer to the “Maintenance Schedule” for the
proper maintenance intervals. Use MOPAR® Type MS-
6560 (lithium-based grease), or equivalent.
766 MAINTAINING YOUR VEHICLE

Points To Remember
NOTE:When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•Do not overfill the coolant expansion bottle.
•Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
•If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
•Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to MS-12106)
and distilled water for proper corrosion protection of
your engine which contains aluminum components.
•Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased emis-
sions.

CAUTION!
•When installing the power distribution center
cover, it is important to ensure the cover is properly
positioned and fully latched. Failure to do so may
allow water to get into the power distribution
center and possibly result in an electrical system
failure.
•When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If
a properly rated fuse continues to blow, it indicates
a problem in the circuit that must be corrected.
VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
•Disconnect the negative cable from battery.
•Any time 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 the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.7
