2019 DODGE DURANGO cooling

NOTE:It is not necessary to move the temperature. The
system automatically adjusts the temperature, mode and
fan speed to provide comfort as quickly as possible.
Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator to
manually activate or deactivate the air conditioning sys-
tem. When the air conditioning system is turned on, cool
dehumidified air will flow through the outlets into the
cabin. For improved fuel economy, press the A/C button to
turn off the air conditioning and manually adjust the
blower and airflow mode settings. Also, make sure to select
only Panel, Bi-Level, or Floor modes.
NOTE:
• For Manual Climate Controls, if the system is in Mix,
Floor or Defrost Mode, the A/C can be turned off, but
the A/C system shall remain active to prevent fogging of
the windows.
• If fog or mist appears on the windshield or side glass,
select Defrost mode, and increase blower speed if
needed. •
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 the front of
the radiator and through the condenser.
MAX A/C
MAX A/C sets the control for maximum cooling perfor-
mance.
Press and release to toggle between MAX A/C and the
prior settings. The button illuminates when MAX A/C is
on.
In MAX A/C, the blower level and mode position can be
adjusted to desired user settings. Pressing other settings
will cause the MAX A/C operation to switch to the selected
setting and MAX A/C to exit.
Recirculation
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.

CAUTION!
Interior air enters the Rear Automatic Temperature
Control System through an intake grille, located in the
right side trim panel behind the third row seats. The
heater outlets are located in the right side trim panel,
just behind the sliding door. Do not block or place
objects directly in front of the inlet grille or heater
outlets. The electrical system could overload causing
damage to the blower motor.
Rear Temperature Control
To change the temperature in the rear of the vehicle, push
the temperature buttons. The rear temperature settings are
displayed in the rear ATC panel.
When rear controls are locked by the front system, the Rear
Temperature Lock symbol on the ATC panel is illuminated
and any rear overhead adjustments are ignored.
When the Sync feature is active, the rear temperature is
synchronized to the driver ’s temperature setting. If the rear
temperature is changed, the Sync feature will deactivate.
Operating Tips
NOTE: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. A
solution of 50% OAT (Organic Additive Technology) cool-
ant that meets the requirements of FCA Material Standard
MS.90032 and 50% water is recommended. Refer to “Fluids
and Lubricants” in “Technical Specifications” for proper
coolant selection.
Winter Operation
Use of the Air Recirculation mode during winter months is
not recommended because it may cause window fogging.
Vacation/Storage
Before 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 on high. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.

Instrument Cluster Descriptions
1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Speedometer •Indicates vehicle speed.
3. Temperature Gauge •The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats. If you decide to look
under the hood yourself, see “Servicing And Mainte-
nace”. Follow the warnings under the Cooling System
Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age 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”, turn the engine off immediately and call an
authorized dealer for service.

SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE CARGO
AREA.
WARNING!
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
• It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seriously
injured or killed.
• Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat belts.
• Be sure everyone in your vehicle is in a seat and
using a seat belt properly.
Exhaust Gas
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 even-
tually 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/liftgate/
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 con-
trols to force outside air into the vehicle. Set the
blower at high speed.
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
