Warning Lights And Messages; Red Warning Lights - RAM 1500 2025 Owner's Manual

112 GETTING TO KNOW YOUR INSTRUMENT PANEL
●
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 +12 Volts, 115 Volts AC,
USB ports) during certain driving conditions (city
driving, towing, frequent stopping).
●
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 Volts, 115 Volts 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
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
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.

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.
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.
