2019 Ram 1500 warning light

WARNING!
To avoid serious injury or death:
•Only devices designed for use in this type of outlet
should be inserted into any 12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while driving the
vehicle.
• If this outlet is mishandled, it may cause an electric
shock and failure.
CAUTION!
• Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent the
engine from starting.
(Continued)
CAUTION! (Continued)
•Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these intermit-
tently and with greater caution.
• After the use of high power draw accessories, or long
periods of the vehicle not being started (with acces-
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the generator to
recharge the vehicle’s battery.

Battery Saver On/Battery Saver Mode Message —
Electrical Load Reduction Actions — If Equipped
This vehicle is equipped with an Intelligent Battery Sensor
(IBS) to perform additional monitoring of the electrical
system and status of the vehicle battery.
In cases when the IBS detects charging system failure, or
the vehicle battery conditions are deteriorating, electrical
load reduction actions will take place to extend the driving
time and distance of the vehicle. This is done by reducing
power to or turning off non-essential electrical loads. Load reduction is only active when the engine is running.
It will display a message if there is a risk of battery
depletion to the point where the vehicle may stall due to
lack of electrical supply, or will not restart after the current
drive cycle.
When load reduction is activated, the message “Battery
Saver On Some Systems May Have Reduced Power” 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 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.

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 the
evaluation of the vehicle and driving pattern 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 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 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
4
GETTING TO KNOW YOUR INSTRUMENT PANEL 179

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 isindicated 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
180 GETTING TO KNOW YOUR INSTRUMENT PANEL

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.
— Hood Open Warning Light
This warning light will illuminate when the hood is
ajar/open and not fully closed.
NOTE: If the vehicle is moving, there will also be a single
chime.
— Vehicle Security Warning Light — If Equipped
This light will flash at a fast rate for approximately 15
seconds when the vehicle security alarm is arming, and
then will flash slowly until the vehicle is disarmed.
— 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
temperature reading does not return to normal, turn the
engine off immediately and call for service.
Refer to “If Your Engine Overheats” in “In Case Of
Emergency” for further information.
— Battery Charge Warning Light
This warning light will illuminate when the battery is not
charging properly. If it stays on while the engine is run-
ning, there may be a malfunction with the charging system.
Contact an authorized dealer as soon as possible.
This indicates a possible problem with the electrical system
or a related component.
— Oil Pressure Warning Light
This warning light will illuminate to indicate low engine
oil pressure. If the light turns on while driving, stop the
