2019 DODGE DURANGO overheating

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.
102 GETTING TO KNOW YOUR VEHICLE

3. Push and hold the Homelink button you want toprogram while you push and hold the hand-held trans-
mitter button.
4. Continue to hold both buttons and observe the indicator light. The Homelink indicator will flash slowly and then
rapidly after HomeLink has received the frequency
signal from the hand-held transmitter. Release both
buttons after the indicator light changes from slow to
rapid.
5. Push and hold the programmed HomeLink button and observe the indicator light.
• If the indicator light stays on constantly, programming
is complete and the garage door/device should acti-
vate when the HomeLink button is pushed.
• To program the two remaining HomeLink buttons,
repeat each step for each remaining button. DO NOT
erase the channels.
Canadian/Gate Operator Programming
For programming transmitters in Canada/United States
that require the transmitter signals to “time-out” after
several seconds of transmission: Canadian radio frequency laws require transmitter signals
to time-out (or quit) after several seconds of transmission,
which may not be long enough for HomeLink to pick up
the signal during programming. Similar to this Canadian
law, some U.S. gate operators are designed to time-out in
the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage door
or gate motor.
1. Cycle the ignition to the ON/RUN position.
NOTE:
For vehicles equipped with Keyless Enter-N-Go,
place the ignition in the RUN position with the engine ON.
Make sure while programming HomeLink with the engine
ON that your vehicle is outside of your garage, or that the
garage door remains open at all times.
2. Place the hand-held transmitter 1 to 3 inches (3 to 8 cm) away from the HomeLink button you wish to program
while keeping the HomeLink indicator light in view.
3. Continue to push and hold the HomeLink button while you push and release (“cycle”) your hand-held trans-
mitter every two seconds until HomeLink has success-
fully accepted the frequency signal. The indicator light
will flash slowly and then rapidly when fully trained.

5. Start the engine in the vehicle that has the boosterbattery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.
CAUTION!
Do not run the booster vehicle engine above 2,000 rpm
since it provides no charging benefit, wastes fuel, and
can damage booster vehicle engine.
6. Once the engine is started, remove the jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative (-)end of the jumper cable from
the remote negative (-)post of the discharged vehicle.
2. Disconnect the opposite end of the negative (-)jumper
cable from the negative (-)post of the booster battery.
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 remote positive (+)post of the discharged
vehicle. 5. Reinstall the protective cover over the remote positive
(+) post of the discharged vehicle.
If frequent jump starting is required to start your vehicle
you should have the battery and charging system tested 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 by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase the engine idle speed
while preventing vehicle motion with the brakes.
404 IN CASE OF EMERGENCY

WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle’s wheels
faster than 30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when you are
stuck and do not let anyone near a spinning wheel, no
matter what the speed.
CAUTION!
•Racing the engine or spinning the wheels may lead
to transmission overheating and failure. Allow the
engine to idle with the transmission in NEUTRAL
for at least one minute after every five rocking-
motion cycles. This will minimize overheating and
(Continued)
CAUTION! (Continued)
reduce the risk of transmission failure during pro-
longed efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shifting between
DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis-
sion shifting occurring).
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service. If the transmis-
sion and drivetrain are operable, disabled vehicles may
also be towed as described under “Recreational Towing” in
“Starting And Operating”.

IN CASE OF EMERGENCY 409

In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
•Do not interrupt the ignition when the transmission is in
gear and the vehicle is in motion.
• Do not try to start the vehicle by pushing or towing the
vehicle.
• Do not idle the engine with any ignition components
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.
Cooling System
WARNING!
•You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
(Continued)
WARNING! (Continued)
do not open the hood until the radiator has had time
to cool. Never open a cooling system pressure cap
when the radiator or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry away from
the radiator cooling fan when the hood is raised. The
fan starts automatically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling fan, discon-
nect the fan motor lead or turn the ignition to the
OFF mode. The fan is temperature controlled and can
start at any time the ignition is in the ON mode.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable). If the engine coolant (antifreeze) is dirty, the system
should be drained, flushed, and refilled with fresh OAT
coolant (conforming to MS.90032) by an authorized dealer.
Check the front of the A/C condenser for any accumula-
tion of bugs, leaves, etc. If dirty, clean by gently spraying
water from a garden hose vertically down the face of the
condenser.
440 SERVICING AND MAINTENANCE

WARNING!
Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the rec-
ommended load capacity for your vehicle. Never over-
load them.
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary areas
are affected by improper tire pressure:
•Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride Comfort Safety
WARNING!
•
Improperly inflated tires are dangerous and can
cause collisions.
• Underinflation increases tire flexing and can result
in overheating and tire failure.
• Overinflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can cause
damage that result in tire failure.
• Overinflated or underinflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
• Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the right
or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Both under-inflation and over-inflation affect the stability
of the vehicle and can produce a feeling of sluggish
response or over responsiveness in the steering.
