2019 DODGE GRAND CARAVAN air conditioning

CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condition-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.
Refrigerant Recovery And Recycling R-134a — If
Equipped
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is an ozone-friendly substance. The
manufacturer recommends that air conditioning service be
performed by an authorized dealer or other service facili-
ties using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C system PAG
compressor oil and refrigerants.
A/C Air Filter
Refer to the “Maintenance Plan” in the “Scheduled Servic-
ing” chapter for the proper maintenance 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 A/C 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. Push in on the sides of the glove compartment, remove tether and lower the door.
3. Pivot the glove compartment downward.
4. Disengage the two retaining tabs that secure the filter cover to the HVAC housing, and remove the cover.

SERVICING AND MAINTENANCE 345

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.90032) and distilled water for proper corrosion pro-
tection of your engine which contains aluminum com-
ponents.
• 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 emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. Driving with your foot resting or riding
on the brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible
brake damage. You would not have your full braking
capacity in an emergency.
354 SERVICING AND MAINTENANCE

WARNING!
The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, under-inflation, or excessive load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days, you may want to take steps to protect your battery.
You may do the following:
• Remove the 60 Amp cartridge in the Totally Integrated
Power Module (TIPM) labeled Ignition-Off Draw (IOD).
• Or, disconnect the negative cable from the battery.
• Anytime you store your vehicle, or keep it out of service
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 lubri-
cation to minimize the possibility of compressor damage
when the system is started again.
BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according to geographic
locations and usage. Chemicals that make roads passable in
snow and ice and those that are sprayed on trees and road
surfaces during other seasons are highly corrosive to the
metal in your vehicle. Outside parking, which exposes your
vehicle to airborne contaminants, road surfaces on which the
vehicle is operated, extreme hot or cold weather and other
extreme conditions will have an adverse effect on paint,
metal trim, and underbody protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion resis-
tance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of paint
and protective coatings from your vehicle.
The most common causes are:
• Road salt, dirt and moisture accumulation.
• Stone and gravel impact.
• Insects, tree sap and tar.

SERVICING AND MAINTENANCE 381

NOTE:If you do not say a command within a few seconds,
the system will present you with a list of options.
If you would like to interrupt the system while it lists
options, push the Voice Command
button, listen for
the beep, and say your command.
Pushing the Voice Commandbutton while the system
is speaking is known as “barging in.” The system will be
interrupted, and after the beep, you can add or change
commands. This will become helpful once you start to
learn the options.
NOTE: At any time, you can say the words “Cancel,”
“Help” or “Main Menu.”
These commands are universal and can be used from any
menu. All other commands can be used depending upon
the active application.
When using this system, you should speak clearly and at a
normal speaking volume.
The system will best recognize your speech if the windows
are closed, and the heater/air conditioning blower is set to
low.
At any point, if the system does not recognize one of your
commands, you will be prompted to repeat it. To hear the first available Menu, push the Voice Command
button and say “Help” or “Main Menu.”
Commands
The Voice Command system understands two types of
commands, Universal commands and Local commands.
Universal commands are available at all times. Local
commands are available if the supported radio mode is
active.
Changing The Volume
1. Start a dialogue by pushing the Voice Commandbut-
ton.
2. Say a command (e.g., “Help”).
3. Use the ON/OFF VOLUME rotary knob to adjust the volume to a comfortable level while the Voice Com-
mand system is speaking. Please note the volume set-
ting for Voice Command is different than the audio
system.
Main Menu
Start a dialogue by pushing the Voice Commandbut-
ton. You may say “Main Menu” to switch to the main
menu. 10
