air condition DODGE GRAND CARAVAN 2019 Owner's Manual

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 a competent mechanic inspect the complete
exhaust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, inspect the ex-
haust system each time the vehicle is raised for lubrication
or oil change. Replace as required.
Safety Checks You Should Make Inside The Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a collision.
Rear seat belt assemblies must be replaced after a collision
if they have been damaged (i.e., bent retractor, torn web-
bing, etc.). If there is any question regarding seat belt or
retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for four to
eight seconds as a bulb check when the ignition switch
is first turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while driving,
have the system inspected at an authorized dealer as
soon as possible. After the bulb check, this light will
illuminate with a single chime when a fault with the Air
Bag System has been detected. It will stay on until the
fault is removed. If the light comes on intermittently or
remains on while driving, have an authorized dealer
service the vehicle immediately.
Refer to “Occupant Restraint Systems” in “Safety” for
further information.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See an autho-
rized dealer for service if your defroster is inoperable.

SAFETY 235

Automatic Transmission
The DRIVE range can be selected when towing. However,
if frequent shifting occurs while in DRIVE, use the Elec-
tronic Range Select (ERS) shift control to manually select a
lower gear range.
NOTE:Using a lower gear range while operating the
vehicle under heavy loading conditions, will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup. This action will also
provide better engine braking.
If you REGULARLY tow a trailer for more than 45 minutes
of continuous operation, then change the transmission
fluid and filter as specified for police, taxi, fleet, or
frequent trailer towing. Refer to the “Maintenance Plan”
for the proper maintenance intervals.
Electronic Range Select (ERS)
• When using the ERS shift control, select the highest gear
that allows for adequate performance and avoids fre-
quent downshifts. For example, choose “4” if the desired
speed can be maintained. Choose “3” or “2” if needed to
maintain the desired speed. •
To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as necessary
to avoid extended driving at high RPM. Return to a
higher gear range or vehicle speed when grade and road
conditions allow.
Speed Control — If Equipped
• Do not use on hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission overheat-
ing, take the following actions:
City Driving
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.
280 STARTING AND OPERATING

•The Sealant Bottle is a one tire application use and needs
to be replaced after each use. Always replace these
components immediately at your original equipment
vehicle dealer.
• When the Tire Service Kit sealant is in a liquid form,
clean water, and a damp cloth will remove the material
from the vehicle or tire and wheel components. Once the
sealant dries, it can easily be peeled off and properly
discarded.
• For optimum performance, make sure the valve stem on
the wheel is free of debris before connecting the Tire
Service Kit.
• The Tire Service Kit Sealant is only intended to seal
punctures less than 1/4 inch (6 mm) diameter in the
tread/contact surface of your vehicle’s tires.
• The Tire Service Kit Sealant is not intended to seal
punctures on the tires’ side walls.
• You can use the Tire Service Kit air pump to inflate
bicycle tires. The kit also comes with two needles,
located in the Accessory Storage Compartment (on the
bottom of the air pump) for inflating sport balls, rafts, or
similar inflatable items. However, use only the Air Pump and make sure the Mode Select Knob is in the Air Mode
when inflating such items to avoid injecting sealant into
them.
• Do not lift or carry the Tire Service Kit by the hoses.
WARNING!
•Do not attempt to seal a tire on the side of the vehicle
closest to traffic. Pull far enough off the road to avoid
the danger of being hit when using the Tire Service
Kit.
• Do not use Tire Service Kit or drive the vehicle under
the following circumstances:
– If the puncture in the tire tread is approximately 1/4 inch (6 mm) or larger.
– If the tire has any sidewall damage.
– If the tire has any damage from driving with extremely low tire pressure.
– If the tire has any damage from driving on a flat tire.
– If the wheel has any damage.
– If you are unsure of the condition of the tire or the wheel.

3. Disconnect the positive(+)end of the jumper cable from
the positive (+)post of the booster battery.
4. Disconnect the opposite end of the positive (+)jumper
cable from the positive (+)post of the vehicle with the
discharged battery.
If frequent jump starting is required to start your vehicle,
you should have the battery and charging system in-
spected at an authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets
draw power from the vehicle’s battery, even when not
in use (i.e., cellular devices, etc.). Eventually, if plugged
in long enough without engine operation, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating your engine by taking the appro-
priate action.
• On the highways — slow down. •
In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads “H,” pull over
and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H” and you hear continuous chimes, turn the engine
off immediately and call for service.
NOTE: There are steps that you can take to slow down an
impending overheat condition:
• If your Air Conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine cooling system.

SERVICING AND MAINTENANCE 337

Engine Air Cleaner Filter
Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
NOTE:Be sure to follow the “Severe Duty Conditions”
maintenance interval if applicable.
WARNING!
The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the ve-
hicle with the air induction system (air cleaner, hoses,
etc.) removed. Failure to do so can result in serious
personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters varies
considerably. Only high quality filters should be used to
assure most efficient service. Mopar engine air cleaner
filters are a high quality filter and are recommended.
Air Conditioner Maintenance
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and a performance test.
Drive belt tension should also be checked at this time.
WARNING!
• Use only refrigerants and compressor lubricants ap-
proved by the manufacturer for your air conditioning
system. Some unapproved refrigerants are flam-
mable and can explode, injuring you. Other unap-
proved refrigerants or lubricants can cause the sys-
tem to fail, requiring costly repairs. Refer to
Warranty Information Book, for further warranty
information.
• The air conditioning system contains refrigerant un-
der high pressure. To avoid risk of personal injury or
damage to the system, adding refrigerant or any
repair requiring lines to be disconnected should be
done by an experienced technician.
344 SERVICING AND MAINTENANCE

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.
