2015 Ram ProMaster air condition

The Manual Temperature Controls consist of a series of
three outer rotary dials (blower speed, temperature and
mode) and three inner push buttons (Recirculation, A/C,
Rear Window Defroster).
Blower Control
Rotate this control to regulate the
amount of air forced through the ven-
tilation system in any mode. The
blower speed increases as you move
the control to the right from the “O”
(OFF) position. There are seven blower
speeds.
Temperature Control
Rotate this control to regulate the tem-
perature of the air inside the passenger
compartment. Rotating the dial left
into the blue area of the scale indicates
cooler temperatures, while rotating
right into the red area indicates
warmer temperatures.
NOTE: If your air conditioning performance seems lower
than expected, check the front of the A/C condenser
located in front of the radiator for an accumulation of dirt
or insects. Clean with a gentle water spray from behind
the radiator and through the condenser. Fabric front
fascia protectors may reduce airflow to the condenser,
reducing air conditioning performance.

Air Conditioning Control
Push this button to engage the Air
Conditioning. A light will illuminate
when the Air Conditioning system is
engaged. Rotating the dial left into the
blue area of the scale indicates cooler
temperatures, while rotating right into
the red area indicates warmer
temperatures.
• Economy Mode
If economy mode is desired, push the A/C button to turn
OFF the indicator light and the A/C compressor. Then,
select Panel, Bi-Level or Floor mode and move the
temperature control to the desired temperature.
Mode Control (Air Direction)
Rotate this control to choose from sev-
eral patterns of air distribution. You
can select either a primary mode as
identified by the symbols on the con-
trol, or a blend of two of these modes.
The closer the setting is to a particular
symbol, the more air distribution you
receive from that mode.
• Panel
Air is directed through the outlets in the instru-
ment panel. These outlets can be adjusted to direct
airflow.
NOTE: The center instrument panel outlets can be aimed
so that they are directed toward the rear seat passengers
for maximum airflow to the rear.

•Bi-Level
Air is directed through the panel and floor outlets.
NOTE: For all settings, except full cold or full hot,
there is a difference in temperature between the upper
and lower outlets. The warmer air flows to the floor
outlets. This feature gives improved comfort during
sunny but cool conditions.
• Floor
Air is directed through the floor outlets with a
small amount flowing through the defrost and
side window demist outlets.
• Mix
Air is directed through the floor, defrost, and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat to the
windshield. This setting is good for maintaining comfort
while reducing moisture on the windshield. •
Defrost
Air is directed through the windshield and side
window demist outlets. Use this mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting.
NOTE: The air conditioning compressor operates in Mix,
Defrost, or a blend of these modes, even if the Air
Conditioning (A/C) button is not pushed. This dehu-
midifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.

Recirculation ControlPushing the Recirculation Control button will
put the system in recirculation mode. This can
be used when outside conditions such as
smoke, odors, dust, or high humidity are pres-
ent. Activating recirculation will cause the LED in the
control button to illuminate.
Continuous use of the Recirculation mode may make the
inside air stuffy and window fogging may occur. Ex-
tended use of this mode is not recommended.
The use of the Recirculation mode in cold or damp
weather will cause windows to fog on the inside, because
of moisture buildup inside the vehicle. Select the outside
air position for maximum defogging. Recirculated air is not allowed in Defrost modes. If the
Recirculation button is pushed while in Defrost mode,
the LED indicator will flash several times then go out.
Recirculation will be disabled automatically when De-
frost mode is selected.
If the following conditions are verified:
•
Mode Floor, Vent or Bi level selected.
• Temperature in Max Cold.
• A/C led ON.
• Hot Ambient Temperature.
• Blower at Maximum speed.
• In case of hot ambient temperature, the recirculation is
closed (opened for a minute each 15 minutes so the air
can be changed) to improve the vehicle cooling.

Rear Window Defrosting
Push the Rear Defrost button to activate heated rear
window defrosting.
This function switches OFF automatically after about 20
minutes or when the engine is turned OFF. It is not
switched on automatically the next time the engine is
started.
If equipped, push the Rear Defrost button to activate
defrosting of door mirrors and heated nozzles.
NOTE:Do not affix stickers to the inside of the heated
rear window over the heating filaments, to avoid damage
that might cause them to stop working properly.
Additional Rear Climate Control — If Equipped
This switch, mounted on the instrument panel to the left
of the steering column, activates the additional rear
heating/air conditioning system vent. NOTE:
The switch must be enabled for operation by the
Upfitter.

Check and adjust tire pressure with a good quality pocket-
type pressure gauge. Do not make a visual judgement
when determining proper inflation. Tires may look prop-
erly inflated even when they are under-inflated.
•Inspect tires for signs of tire wear or visible damage.
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the valve stem.
Inflation pressures specified on the placard are always
“cold tire inflation pressure”. Cold tire inflation pressure
is defined as the tire pressure after the vehicle has not
been driven for at least three hours, or driven less than 1
mile (1.6 km) after sitting for a minimum of three hours. The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire side-
wall.
Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12°F (7°C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the Winter.
Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F (0°C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
244 STARTING AND OPERATING

Consult an authorized tire dealer for tire repairs and
additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced imme-
diately with another Run Flat tire of identical size and
service description (Load Index and Speed Symbol).
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons (Spring,
Summer, Fall and Winter). Traction levels may vary
between different all season tires. All season tires can be
identified by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in sets of four;
failure to do so may adversely affect the safety and
handling of your vehicle.
Summer Or Three Season Tires — If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in snow or
on ice. If your vehicle is equipped with Summer tires, be
aware these tires are not designed for Winter or cold
driving conditions. Install Winter tires on your vehicle
when ambient temperatures are less than 40°F (5°C) or if
roads are covered with ice or snow. For more informa-
tion, contact an authorized dealer.
Summer tires do not contain the all season designation or
mountain/snowflake symbol on the tire sidewall. Use
Summer tires only in sets of four; failure to do so may
adversely affect the safety and handling of your vehicle.

front or rear axle of your vehicle, but it is not. This spare
tire may have limited tread life. When the tread is worn
to the tread wear indicators, the temporary use full size
spare tire needs to be replaced. Since it is not the same as
your original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle at the
first opportunity.
Limited-Use Spare — If Equipped
The limited-use spare tire is for temporary emergency
use only. This tire is identified by a label located on the
limited-use spare wheel. This label contains the driving
limitations for this spare. This tire may look like the
original equipped tire on the front or rear axle of your
vehicle, but it is not. Installation of this limited-use spare
tire affects vehicle handling. Since it is not the same as
your original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle at the
first opportunity.
WARNING!
Limited-use spares are for emergency use only. In-
stallation of this limited-use spare tire affects vehicle
handling. With this tire, do not drive more than the
speed listed on the limit-use spare wheel. Keep
inflated to the cold tire inflation pressures listed on
your Tire and Loading Information Placard located
on the driver ’s side B-Pillar or the rear edge of the
driver ’s side door. Replace (or repair) the original
equipment tire at the first opportunity and reinstall it
on your vehicle. Failure to do so could result in loss
of vehicle control.
