2023 RAM PROMASTER climate control

42GETTING TO KNOW YOUR VEHICLE
Temperature Control
Temperature Control regulates the temperature of
the air forced through the climate system.
The temperature increases as you press
the red arrow button on the faceplate.
The temperature decreases as you press
the blue arrow button on the faceplate.
You can also adjust the temperature using the
sliding temperature bar on the touchscreen.
Slide the bar upward into the red to increase the
temperature, and slide it downward into the blue to
decrease the temperature.
Blower Control
Blower Control regulates the amount of
air forced through the climate system.
There are seven blower speeds available.
The blower speed increases as you press
the up arrow above the blower control symbol.
The blower speed decreases as you press the
down arrow below the blower control symbol.

You can also adjust the blower speed on the
touchscreen by selecting a speed on the blower bar.

Mode Control

Select Mode by pressing one of the Mode
buttons on the touchscreen, or the faceplate,
to change the airflow distribution mode.
Pushing this button will cycle through the five
mode combinations in order: Face, Face/Feet, Feet,
Windshield/Feet, Windshield. The cycle will repeat if
the button is continually pushed.

NOTE:The distribution modes on the climate control
screen will also illuminate when a selection is
made using the button on the instrument panel.
Panel Mode
Air comes from the outlets in the
instrument panel. Each of these outlets
can be individually adjusted to direct the
flow of air. The air vents out of the center
outlets and outboard outlets can be moved up and
down or side to side to regulate airflow direction.
Move the vent to the furthermost sides to close
the vent.
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 condi -
tions 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.

Defrost Mode

Air comes from the windshield and side
window demist outlets. When the defrost
button is selected, the blower level may
increase. Use Defrost mode with maximum
temperature settings for best windshield and side
window defrosting and defogging. When toggling the
front defrost mode button, the Climate Control system
will return to the previous setting.

Mix Mode
Air is directed through the floor, defrost,
and side window demister 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.

Climate Control ON/OFF.
ADDITIONAL REAR CLIMATE CONTROL —
I
F EQUIPPED
These switches, mounted on the instrument panel
to the left of the steering column, activate the
additional rear heating/air conditioning system.
NOTE:These switches must be enabled for operation by
the Upfitter.

Additional Rear Climate Controls Switches

Rear Blower Control

Push this button to turn on the rear climate
controls. An indicator light will turn on when
the rear climate control is on.

OPERATING TIPS
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
performance, 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
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Ú page 265.
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 air distribution
box, 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 an authorized dealer to
service your cabin air filter, and to have it replaced
when needed.

192SAFETY
(Continued)
EXHAUST GAS
The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the underside
or rear of the vehicle is damaged, have an
authorized dealer inspect the complete exhaust
system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts.
Open seams or loose connections could permit
exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless
and odorless. Breathing it can make you
unconscious and can eventually poison you.
To avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift
-
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to prevent
carbon monoxide poisoning:

Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with the
engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.

Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.
When exiting the vehicle, always make sure
the ignition is in the OFF position, remove the
key fob from the vehicle, and lock your vehicle.

264SERVICING AND MAINTENANCE
TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle
operate at different loads and perform different
steering, driving, and braking functions. For these
reasons, they wear at unequal rates.

These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season
type tires. Rotation will increase tread life, help to
maintain mud, snow and wet traction levels, and
contribute to a smooth, quiet ride.

Refer to the Maintenance Plan for the proper
maintenance intervals Úpage 222. The reasons
for any rapid or unusual wear should be corrected
prior to rotation being performed.
The suggested rotation method is the “forward
cross” shown in the following diagram. This rotation pattern does not apply to some
directional tires that must not be reversed.

Tire Rotation (Forward Cross)

DEPARTMENT OF TRANSPORTATION
UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform
to Federal safety requirements in
addition to these grades.
TREADWEAR
The Treadwear grade is a comparative
rating, based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one and one-half times as well on
the government course as a tire graded
100. The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
TRACTION GRADES

The Traction grades, from highest to lowest,
are AA, A, B, and C. These grades represent
the tire's ability to stop on wet pavement, as
measured under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.

Observe the traction device manufacturer’s
instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed of
the device manufacturer’s if it is less than
30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.
