Dodge Durango (2019 year). Instruction — part 10

NOTE:
• The charging system is independent from load reduc-

tion. The charging system performs a diagnostic on the
charging system continuously.

• If the Battery Charge Warning Light is on it may indicate

a problem with the charging system. Refer to “Battery
Charge Warning Light” in “Getting To Know Your
Instrument Panel” for further information.

The electrical loads that may be switched off (if equipped),
and vehicle functions which can be affected by load
reduction:
• Heated Seat/Vented Seats/Heated Wheel
• Rear Defroster And Heated Mirrors
• HVAC System
• 115V AC Power Inverter System
• Audio and Telematics System
Loss of the battery charge may indicate one or more of the
following conditions:
• The charging system cannot deliver enough electrical

power to the vehicle system because the electrical loads
are larger than the capability of charging system. The
charging system is still functioning properly.

• Turning on all possible vehicle electrical loads (e.g.

HVAC to max settings, exterior and interior lights,
overloaded power outlets +12V, 115V AC, USB ports)
during certain driving conditions (city driving, towing,
frequent stopping, etc.).

• Installing options like additional lights, upfitter electri-

cal accessories, audio systems, alarms and similar de-
vices.

• Unusual driving cycles (short trips separated by long

parking periods).

• The vehicle was parked for an extended period of time

(weeks, months).

• The battery was recently replaced and was not charged

completely.

• The battery was discharged by an electrical load left on

when the vehicle was parked.

• The battery was used for an extended period with the

engine not running to supply radio, lights, chargers,
+12V portable appliances like vacuum cleaners, game
consoles and similar devices.

What to do when an electrical load reduction action
message is present (“Battery Saver On” or “Battery Saver
Mode”)

During a trip:
• Reduce power to unnecessary loads if possible:

– Turn off redundant lights (interior or exterior)
– Check what may be plugged in to power outlets +12V,

115V AC, USB ports

– Check HVAC settings (blower, temperature)
– Check the audio settings (volume)

After a trip:
• Check if any aftermarket equipment was installed (ad-

ditional lights, upfitter electrical accessories, audio sys-
tems, alarms) and review specifications if any (load and
Ignition Off Draw currents).

• Evaluate the latest driving cycles (distance, driving time

and parking time).

• The vehicle should have service performed if the mes-

sage is still present during consecutive trips, and if the
evaluation and driving pattern of the vehicle did not
help to identify the cause.

WARNING LIGHTS AND MESSAGES

The warning/indicator lights will illuminate in the instru-
ment panel together with a dedicated message and/or
acoustic signal when applicable. These indications are
indicative and precautionary and as such must not be
considered as exhaustive and/or alternative to the infor-
mation contained in the Owner’s Instruction, which you are
advised to read carefully in all cases. Always refer to the
information in this chapter in the event of a failure indica-
tion. All active telltales will display first if applicable. The
system check menu may appear different based upon
equipment options and current vehicle status. Some tell-
tales are optional and may not appear.

Red Warning Lights

— Seat Belt Reminder Warning Light

This warning light indicates when the driver or passenger
seat belt is unbuckled. When the ignition is first placed in
the ON/RUN or ACC/ON/RUN position and if the
driver’s seat belt is unbuckled, a chime will sound and the
light will turn on. When driving, if the driver or front
passenger seat belt remains unbuckled, the Seat Belt Re-
minder Light will flash or remain on continuously and a
chime will sound.

Refer to “Occupant Restraint Systems” in “Safety” for
further information.

— Air Bag Warning Light

This warning light will illuminate to indicate a fault with
the air bag, and will turn on for four to eight seconds as a
bulb check when the ignition is placed in the ON/RUN or
ACC/ON/RUN position. This light will illuminate with a
single chime when a fault with the air bag has been
detected, it will stay on until the fault is cleared. If the light
is either not on during startup, stays on, or turns on while
driving, have the system inspected at an authorized dealer
as soon as possible.

— Brake Warning Light

This warning light monitors various brake functions, in-
cluding brake fluid level and parking brake application. If
the brake light turns on it may indicate that the parking
brake is applied, that the brake fluid level is low, or that
there is a problem with the anti-lock brake system reser-
voir.

If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the

master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition has
been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake,
and a brake pedal pulsation may be felt during each stop.

The dual brake system provides a reserve braking capacity
in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.

The light will remain on until the cause is corrected.

NOTE:

The light may flash momentarily during sharp

cornering maneuvers, which change fluid level conditions.
The vehicle should have service performed, and the brake
fluid level checked.

If brake failure is indicated, immediate repair is necessary.

WARNING!

Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.

Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.

Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.

The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.

NOTE:

This light shows only that the parking brake is

applied. It does not show the degree of brake application.

problem is detected while the vehicle is running, the light
will either stay on or flash depending on the nature of the
problem. Cycle the ignition when the vehicle is safely and
completely stopped and the transmission is placed in the
PARK position. The light should turn off. If the light
remains on with the vehicle running, your vehicle will
usually be drivable; however, see an authorized dealer for
service as soon as possible.

NOTE:

This light may turn on if the accelerator and brake

pedals are pressed at the same time.

If the light continues to flash when the vehicle is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The light will

come on when the ignition is placed in the ON/RUN or
ACC/ON/RUN position and remain on briefly as a bulb
check. If the light does not come on during starting, have
the system checked by an authorized dealer.

— Engine Coolant Temperature Warning Light

This warning light warns of an overheated engine condi-
tion. If the engine coolant temperature is too high, this
indicator will illuminate and a single chime will sound. If
the temperature reaches the upper limit, a continuous
chime will sound for four minutes or until the engine is
able to cool: whichever comes first.

If the light turns on while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift
the transmission into NEUTRAL and idle the vehicle. If the

Yellow Warning Lights

— Engine Check/Malfunction Indicator Warning

Light (MIL)

The Engine Check/Malfunction Indicator Light (MIL) is a
part of an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission control sys-
tems. This warning light will illuminate when the ignition
is in the ON/RUN position before engine start. If the bulb
does not come on when turning the ignition switch from
OFF to ON/RUN, have the condition checked promptly.

Certain conditions, such as a loose or missing gas cap, poor
quality fuel, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through

several typical driving styles. In most situations, the ve-
hicle will drive normally and will not require towing.

When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced by an authorized dealer as soon as
possible if this occurs.

WARNING!

A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you drive
slowly or park over flammable substances such as dry
plants, wood, cardboard, etc. This could result in death
or serious injury to the driver, occupants or others.

CAUTION!

Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the vehicle
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.

— Electronic Stability Control (ESC) Active

Warning Light — If Equipped

This warning light will indicate when the Electronic Sta-
bility Control system is Active. The “ESC Indicator Light”
in the instrument cluster will come on when the ignition is
placed in the ON/RUN or ACC/ON/RUN position, and
when ESC is activated. It should go out with the engine
running. If the “ESC Indicator Light” comes on continu-
ously with the engine running, a malfunction has been
detected in the ESC system. If this warning light remains
on after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than
30 mph (48 km/h), see an authorized dealer as soon as
possible to have the problem diagnosed and corrected.
• The “ESC Off Indicator Light” and the “ESC Indicator

Light” come on momentarily each time the ignition is
placed in the ON/RUN or ACC/ON/RUN position.

• The ESC system will make buzzing or clicking sounds

when it is active. This is normal; the sounds will stop
when ESC becomes inactive.

• This light will come on when the vehicle is in an ESC

event.

— Electronic Stability Control (ESC) Off Warning

Light — If Equipped

This warning light indicates the Electronic Stability Control
(ESC) is off.

Each time the ignition is turned to ON/RUN or ACC/ON/
RUN, the ESC system will be on, even if it was turned off
previously.

— Low Washer Fluid Warning Light — If

Equipped

This warning light will illuminate when the windshield
washer fluid is low.

— Tire Pressure Monitoring System (TPMS)

Warning Light

The warning light switches on and a message is displayed
to indicate that the tire pressure is lower than the recom-
mended value and/or that slow pressure loss is occurring.
In these cases, optimal tire duration and fuel consumption
may not be guaranteed.

Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire.

164

GETTING TO KNOW YOUR INSTRUMENT PANEL

CAUTION!

Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.

Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.)

As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat and

can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to main-
tain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunc-
tion indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approximately one
minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction
indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function properly.

4

GETTING TO KNOW YOUR INSTRUMENT PANEL

165

CAUTION!

The TPMS has been optimized for the original equip-
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become inoper-
able. After using an aftermarket tire sealant it is
recommended that you take your vehicle to your au-
thorized dealer to have your sensor function checked.

— Low Fuel Warning Light

When the fuel level reaches approximately 2 gal (7.5 L), this
light will turn on and a chime will sound. The light will
remain on until fuel is added.

— Anti-Lock Brake (ABS) Warning Light

This warning light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition is placed in
the ON/RUN or ACC/ON/RUN position and may stay on
for as long as four seconds.

If the ABS light remains on or turns on while driving, then
the Anti-Lock portion of the brake system is not function-
ing and service is required as soon as possible. However,
the conventional brake system will continue to operate
normally, assuming the Brake Warning Light is not also on.

If the ABS light does not turn on when the ignition is
placed in the ON/RUN or ACC/ON/RUN position, have
the brake system inspected by an authorized dealer.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating prop-
erly, your vehicle will provide excellent performance and
fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see
an authorized dealer for service as soon as possible.

CAUTION!

• Prolonged driving with the MIL on could cause

further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.

• If the MIL is flashing while the vehicle is running,

severe catalytic converter damage and power loss
will soon occur. Immediate service is required.

Onboard Diagnostic System (OBD II) Cybersecurity

Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.

WARNING!

• ONLY an authorized service technician should con-

nect equipment to the OBD II connection port in
order to read the VIN, diagnose, or service your
vehicle.

• If unauthorized equipment is connected to the OBD

II connection port, such as a driver-behavior tracking
device, it may:

• Be possible that vehicle systems, including safety

related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.

• Access, or allow others to access, information

stored in your vehicle systems, including personal
information.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS

In some localities, it may be a legal requirement to pass an
inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.

For states that require an Inspection and Main-
tenance (I/M), this check verifies the “Malfunc-
tion Indicator Light (MIL)” is functioning and is
not on when the engine is running, and that the

OBD II system is ready for testing.

Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not ready
for the I/M test, your vehicle may fail the test.

Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle’s OBD II system is ready, you must do the follow-
ing:

1. Cycle the ignition switch to the ON position, but do not

crank or start the engine.

NOTE:

If you crank or start the engine, you will have to

start this test over.

2. As soon as you cycle the ignition switch to the ON

position, you will see the “Malfunction Indicator Light
(MIL)” symbol come on as part of a normal bulb check.

3. Approximately 15 seconds later, one of two things will

happen:

• The MIL will flash for about ten seconds and then return

to being fully illuminated until you turn OFF the igni-
tion or start the engine. This means that your vehicle’s
OBD II system is not ready and you should not proceed
to the I/M station.

• The MIL will not flash at all and will remain fully

illuminated until you place the ignition in the off posi-
tion or start the engine. This means that your vehicle’s
OBD II system is ready and you can proceed to the I/M
station.

4

GETTING TO KNOW YOUR INSTRUMENT PANEL

171

If your OBD II system is not ready, you should see an
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your vehicle
as you normally would in order for your OBD II system to
update. A recheck with the above test routine may then
indicate that the system is now ready.

Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle serviced
before going to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the engine
running.
