Dodge Ram 2500 (2016 year). Manual

6. Modes

The airflow distribution mode can be adjusted so air
comes from the instrument panel outlets, floor outlets,
and demist outlets. The Mode settings are as follows:

• Panel Mode

Air comes from the outlets in the instrument
panel. Each of these outlets can be individu-
ally adjusted to direct the flow of air. The air

vanes of the center outlets and outboard outlets can
be moved up and down or side to side to regulate
airflow direction. There is a shut off wheel located
below the air vanes to shut off or adjust the amount
of airflow from these outlets.
• Bi-Level Mode

Air comes from the instrument panel outlets
and floor outlets. A slight amount of air is
directed through the defrost and side window

demister outlets.

NOTE:

BI-LEVEL mode is designed under comfort con-

ditions to provide cooler air out of the panel outlets and
warmer air from the floor outlets.

• Floor Mode

Air comes from the floor outlets. A slight
amount of air is directed through the defrost
and side window demister outlets.

• Mix Mode

Air comes from the floor, defrost and side
window demister outlets. This mode works
best in cold or snowy conditions.

NOTE:

The air conditioning compressor operates in MIX

and DEFROST modes even if the A/C button is not
pressed. This dehumidifies the air to help dry the wind-
shield. To improve fuel economy, utilize these modes
only when required.

• If fog or mist appears on the windshield or side glass,

select Defrost mode and adjust blower speed if
needed.

• If your air conditioning performance seems lower than

expected, check the front of the A/C condenser (lo-
cated 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.

high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the RECIRCULATION control button

on the touchscreen or faceplate. Recirculation mode
should only be used temporarily. The recirculation LED
button on the faceplate will illuminate when either
button is selected. Push either button a second time to
turn off the Recirculation mode LED and allow outside
air into the vehicle.

UNDERSTANDING YOUR INSTRUMENT PANEL

437

NOTE:

In cold weather, use of Recirculation mode may

lead to excessive window fogging. The recirculation
feature may be unavailable (button on the touchscreen
greyed out) if conditions exist that could create fogging
on the inside of the windshield. On systems with Manual
Climate Controls, the recirculation mode is not allowed
in Defrost mode to improve window clearing operation.
Recirculation will be disabled automatically if this mode

Automatic Temperature Control (ATC)

Automatic Operation

1. Push the AUTO button on the faceplate or press the

“AUTO” button on the touchscreen.

2. Adjust the temperature you would like the system to

maintain by adjusting the driver and passenger tem-
perature buttons on the faceplate or buttons on the
touchscreen. Once the desired temperature is dis-
played, the system will achieve and automatically
maintain that comfort level.

3. When the system is set up for your comfort level, it is

not necessary to change the temperature. You will
experience the greatest efficiency by simply allowing
the system to function automatically.

NOTE:

• It is not necessary to move the temperature settings.

The system automatically adjusts the temperature,
mode, and blower speed to provide comfort as quickly
as possible.

438

UNDERSTANDING YOUR INSTRUMENT PANEL

• The temperature can be displayed in U.S. or Metric

units

selecting

the

Uconnect

customer-

programmable feature. Refer to the “Uconnect Set-
tings” in this section of the manual.

To provide you with maximum comfort in the Automatic
mode, during cold start-ups the blower fan will remain
on low until the engine warms up. The blower will
increase in speed and transition into Auto mode.

Manual Operation Override

The system allows for manual selection of blower speed,
air distribution mode, A/C status and recirculation con-
trol.

The blower fan speed can be set to any fixed speed by
adjusting the blower control. The fan will now operate at
a fixed speed until additional speeds are selected. This
allows the front occupants to control the volume of air
circulated in the vehicle and cancel the Auto mode.

The operator can also select the direction of the airflow
by selecting one of the available mode settings. A/C
operation and Recirculation control can also be manually
selected in Manual operation.

NOTE:

Each of these features operates independently

from each other. If any feature is controlled manually,
temperature control will continue to operate automati-
cally.

Operating Tips

NOTE:

Refer to the chart at the end of this section for

suggested control settings for various weather condi-
tions.

Summer Operation

The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.

UNDERSTANDING YOUR INSTRUMENT PANEL

439

OAT coolant (conforming to MS.90032) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.

Winter Operation

To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.

Vacation/Storage

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
fresh air with the blower setting in high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

Window Fogging and Frosting

Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost on
the inside of the glass in very cold 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.

NOTE:

Automatic Temperature Controls (ATC) will au-

tomatically adjust the climate control settings to reduce
or eliminate window fogging on the front windshield.
When this occurs, recirculation will be unavailable.

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, can cause
odor, and if they enter the plenum they could plug the
water drains. In winter months, ensure the air intake is
clear of ice, slush and snow.
