BATTERY SAVER ON/BATTERY
SAVER MODE MESSAGE —
ELECTRICAL LOAD REDUCTION
ACTIONS — IF EQUIPPED
This vehicle is equipped with an Intelligent Battery Sen-
sor (IBS) to perform additional monitoring of the electri-
cal system and status of the vehicle battery.
In cases when the IBS detects charging system failure,
or the 12 Volt vehicle battery conditions are deteriorat-
ing, 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 12 Volt electrical loads. Load reduction will be
functional when the vehicle propulsion system is active.
The vehicle may not be running depending on the High
Voltage (HV) battery State Of Charge (SOC) or tempera-
ture. 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 12 Volt load reduction is activated, the message
“Battery Saver On” or “Battery Saver Mode” will appear
in the instrument cluster display.
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 diagnos-
tic on the charging system continuously.
•
If the Battery Charge Warning Light is on it may indi-
cate a problem with the charging system
page 65
.
The following are 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
•
Heated/Cooled Cup Holders — If Equipped
•
Rear Defroster And Heated Mirrors
•
HVAC System
•
115 Volts 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 electri-
cal power to the vehicle system because the electri-
cal 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, 150W, USB
ports) during certain driving conditions (city driving,
towing, frequent stopping).
•
Installing options like additional lights, upfitter elec-
trical accessories, audio systems, alarms and simi-
lar 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, char-
gers, +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, 150W, 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.
