2021 DODGE DURANGO warning lights

90GETTING TO KNOW YOUR INSTRUMENT PANEL
When load reduction is activated, the message
“Battery Saver On” or “Battery Saver Mode” will
appear in the instrument cluster.
These messages indicate the vehicle battery has a
low state of charge and continues to lose electrical
charge at a rate that the charging system cannot
sustain.
NOTE:
The charging system is independent from load
reduction. The charging system performs a diag -
nostic on the charging system continuously.
If the Battery Charge Warning Light is on it may
indicate a problem with the charging system
Ú page 92.
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
115 Volt 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 the 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 +12 Volt,
115 Volt AC, USB ports) during certain driving
conditions (city driving, towing, frequent stop
-
ping, etc.).
Installing options like additional lights, upfitter
electrical accessories, audio systems, alarms
and similar devices.
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, +12 Volt 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 +12 Volt, 115 Volt AC, USB ports
Check HVAC settings (blower, temperature)
Check the audio settings (volume)
After a trip:
Check if any aftermarket equipment was
installed (additional lights, upfitter electrical
accessories, audio systems, 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 message 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
instrument 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 information contained in
the Owner’s Manual, which you are advised to read
carefully in all cases. Always refer to the
information in this chapter in the event of a failure
indication. All active telltales will display first if
applicable. The system check menu may appear
different based upon equipment options and
current vehicle status. Some telltales 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 Reminder Light
will flash or remain on continuously and a chime
will sound Ú page 204.
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, including 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 reservoir.
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.

Vehicle Security Warning Light —
If Equipped
This light will flash at a fast rate for
approximately 15 seconds when the
vehicle security system is arming, and
then will flash slowly until the vehicle is
disarmed.
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 systems. 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 vehicle 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.
Electronic Stability Control (ESC) Active
Warning Light
This warning light will indicate when the
ESC 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
continuously 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.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.

STARTING AND OPERATING113
When additional traction is required, the transfer
case AWD LOW position can be used to lock the
front and rear driveshafts together forcing the front
and rear wheels to rotate at the same speed. This
is accomplished by pushing the AWD LOW switch
Ú page 114. The AWD LOW position is designed for
loose, slippery road surfaces only. Driving in the
AWD LOW position on dry, hard surfaced roads
may cause increased tire wear and damage to the
driveline components.
Transfer Case Position Indicator Messages
The Transfer Case Position Indicator message
(AWD LOW) is located in the instrument cluster and
indicate the current and desired transfer case
selection Ú page 83. When you select a different
transfer case position, the position indicator lights
will do the following:
If All Shift Conditions Are Met:

1. The current position indicator light will turn off.

2. The selected position indicator light will flash until the transfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and
remain on. If shift conditions are not met, one or more of the
following events may occur:

1. The indicator light for the current position will
remain on.

2. The newly selected position indicator light will continue to flash.
3. The transfer case will not shift.
NOTE:Before retrying a selection, make certain that all
the necessary requirements for selecting a new
transfer case position have been met Úpage 114.
The “SERV AWD” Warning Light monitors the
electronic shift all-wheel drive system. If this light
remains on after engine start up or illuminates
during driving, it means that the all-wheel drive
system is not functioning properly and that service
is required.
NOTE:Do not attempt to make a shift while only the front
or rear wheels are spinning. This could cause
damage to driveline components.
When operating your vehicle in AWD LOW, the
engine speed is approximately three times that of
the AWD AUTO position at a given road speed. Take
care not to overspeed the engine and do not
exceed 25 mph (40 km/h).
Proper operation of all-wheel drive vehicles
depends on tires of equal size, type and
circumference on each wheel. Any difference in
tire size can cause damage to the transfer case.
Because all-wheel drive provides improved
traction, there is a tendency to exceed safe turning
and stopping speeds. Do not go faster than road
conditions permit.
For additional information on the appropriate use
of each transfer case mode position, see the
information below:
AWD LOW
All-Wheel Drive Low Range – This range provides
low speed all-wheel drive. Locks the front and rear
driveshafts together forcing the front and rear
wheels to rotate at the same speed. Additional
traction and maximum pulling power for loose,
slippery road surfaces only. Do not exceed 25 mph
(40 km/h).
WARNING!
Always engage the parking brake when powering
down the vehicle if the “SERV AWD Warning
Light” is illuminated. Not engaging the parking
brake may allow the vehicle to roll which may
cause personal injury.

114STARTING AND OPERATING
NEUTRAL (N)
This range disengages both the front and rear
driveshafts from the powertrain. To be used for flat
towing behind another vehicle Ú page 153.
SHIFTING PROCEDURE
NOTE:
If any of the requirements to select a new
transfer case position have not been met, the
transfer case will not shift. The position indi -
cator light for the previous position will remain
on and the newly selected position indicator
light will continue to flash until all the require -
ments for the selected position have been met.
To retry a shift: return the control switch back to
the original position, make certain all shift
requirements have been met, wait five seconds
and try the shift again.
If all the requirements to select a new transfer
case position have been met, the current posi -
tion indicator light will turn off, the selected posi -
tion indicator light will flash until the transfer
case completes the shift. When the shift is
complete, the position indicator light for the
selected position will stop flashing and remain
on.
AWD AUTO To AWD LOW
NOTE:When shifting into or out of AWD LOW some gear
noise may be heard. This noise is normal and is not
detrimental to the vehicle or occupants.
Shifting can be performed with the vehicle rolling
2 to 3 mph (3 to 5 km/h) or completely stopped.
Use either of the following procedures:
Preferred Procedure

1. With the engine running, slow the vehicle to 2 to 3 mph (3 to 5 km/h).

2. Shift the transmission into NEUTRAL.
3. While still rolling, push the AWD LOW control switch.
4. After the AWD LOW position indicator light is on (not flashing), shift the transmission back into
gear. Alternate Procedure

1. Bring the vehicle to complete stop.

2. With the ignition in ON/RUN position and
engine running, shift the transmission to
NEUTRAL.
3. Push the AWD LOW control switch.
4. After the AWD LOW position indicator light is on (not flashing), shift the transmission back into
gear.NOTE:
If steps 1 or 2 of either the “Preferred” or “Alter -
nate Procedure” are not satisfied prior to
attempting the shift or if they no longer are
being met while the shift attempt is in process,
the desired position indicator light will flash
continuously while the original position indicator
light is on, until all requirements have been met.
The ignition switch must be in the ON/RUN posi -
tion for a shift to take place and for the position
indicator lights to be operable. If the ignition
switch is not in the ON/RUN position, then the
shift will not take place and no position indicator
lights will be on or flashing.
N (Neutral) Shift Procedure
For information regarding the transfer case N
(Neutral) shift procedure, see Ú page 154.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the NEUTRAL position without first fully
engaging the parking brake. The transfer case
NEUTRAL position disengages both the front and
rear drive shafts from the powertrain and will
allow the vehicle to roll, even if the transmission
is in PARK. The parking brake should always be
applied when the driver is not in the vehicle.

21_WD_OM_EN_USC_t.book Page 114

126STARTING AND OPERATING
To increase the distance setting, push the
Distance Increase button and release. Each time
the button is pushed, the distance setting
increases by one bar (longer).
To decrease the distance setting, push the
Distance Decrease button and release. Each time
the button is pushed, the distance setting
decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving vehicle
is detected in the same lane, the instrument
cluster display will show the ACC Set With Target
Detected Indicator Light. The system will then
adjust the vehicle speed automatically to maintain
the distance setting, regardless of the set speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed above
the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages Ú page 123.
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:The brake lights will illuminate whenever the ACC
system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE!” will flash in the
instrument cluster display and a chime will sound
while ACC continues to apply its maximum braking
capacity.
NOTE:The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the Forward
Collision Warning system is applying the brakes
autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (ACC)
engaged and following a vehicle, the system will
provide an additional acceleration up to the ACC
set speed to assist in passing the vehicle. This
additional acceleration is triggered when the driver
utilizes the left turn signal and will only be active
when passing on the left hand side.
ACC Operation At Stop
If the ACC system brings your vehicle to a standstill
while following a vehicle ahead, your vehicle will
resume motion, without any driver interaction, if
the vehicle ahead starts moving within two
seconds of your vehicle coming to a standstill.
If the target vehicle does not start moving within
two seconds of your vehicle coming to a standstill,
the ACC with Stop system will cancel and the
brakes will release. A cancel message will display
on the instrument cluster display and produce a
warning chime. Driver intervention will be required
at this moment.
While ACC with Stop is holding your vehicle at a
standstill, if the driver seat belt is unbuckled or the
driver door is opened, the ACC with Stop system
will cancel and the brakes will release. A cancel
message will display on the instrument cluster
display and produce a warning chime. The driver
must now manually operate the vehicle’s
accelerator and brakes.
WARNING!
When the ACC system is resumed, the driver
must ensure that there are no pedestrians,
vehicles or objects in the path of the vehicle.
Failure to follow these warnings can result in a
collision and death or serious personal injury.
