Battery Saver Mode/Battery Saver On Message - If Equipped

WARNING: This page is about a different car, the 2017 Dodge Charger. However, it is still accessible from the selected car via links, so may be relevant.

Electrical Load Reduction Actions

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, an 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" or "Battery Saver Mode" will appear in the Electronic Vehicle Information Center (EVIC) or Driver Information Display (DID).

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 diagnostic on the charging system continuously.
If the Charging System Light is on it may indicate a problem with the charging system.

The electrical loads that may be switched off (if equipped), and vehicle functions which can be effected by load reduction:

Heated Seat/Vented Seats/Heated Wheel
Heated/Cooled Cup Holders
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:

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).
Installing options like additional lights, up-fitters, audio systems, alarms and similar devices.
Unusual driving cycles (short trips separated by long parking periods).
The battery aging.
The vehicle was parking for 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 is parked.
The battery was used during parking time to supply radio, lights, chargers, +12V portable appliances like vacuum cleaner's, game consoles and similar devices.

What to do when the electrical load reduction actions message is present ("Battery Saver On" or "Battery Saver Mode")

- During 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 trip:

Check if any aftermarket equipment was installed (additional lights, up-fitters, 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).
Review the chapter of this owner's manual regarding the battery maintenance.
