106 GETTING TO KNOW YOUR INSTRUMENT PANEL
BATTERY SAVER ON/BATTERY SAVER
M
ODE MESSAGE — ELECTRICAL LOAD
R
EDUCTION 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” 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 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 this chapter for further infor-
mation.
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
Rear Defroster And Heated Mirrors
HVAC System
150W 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 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, over-
loaded power outlets +12 Volt, 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 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 cleaner’s,
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, 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.
