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 12 Volt 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
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 HV battery SOC or temperature. 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 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 information.
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 — If Equipped
Rear Defroster And Heated Mirrors
HVAC System
115 Volts AC Power Inverter System
Audio and Telematics System

GETTING TO KNOW YOUR INSTRUMENT PANEL139
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, overloaded power outlets +12
Volts, 150W, 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 appli-
ances 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 exte -
rior)
Check what may be plugged in to power
outlets +12 Volts, 150W, USB ports
Check HVAC settings (blower, tempera -
ture)
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 consecu
-
tive trips and the evaluation of the vehicle
and driving pattern did not help to identify the
cause.

STARTING AND OPERATING235
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to reduce
fuel consumption. The system will stop the
engine automatically during a vehicle stop if the
required conditions are met. Releasing the
brake pedal, pressing the accelerator pedal or
shifting out of DRIVE (D) will automatically
re-start the engine.
This vehicle has been upgraded with a heavy
duty starter, enhanced battery, and other
upgraded engine parts to handle the additional
engine starts.
Auto Stop/Start
The Stop/Start feature is enabled
after every normal customer engine
start. At that time, the system will go
into STOP/START READY and if all
other conditions are met, can go into a STOP/
START AUTOSTOP ACTIVE.
To Activate Auto STOP/START, The Following
Must Occur:
The system must be in STOP/START READY
state. A STOP/START READY message will be
displayed in the instrument cluster within the Stop/Start section. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
The vehicle must be completely stopped.
The shifter must be in a forward gear and the
brake pedal depressed.
The engine will shut down, the tachometer will
move to the zero position and the Stop/Start
telltale will illuminate indicating you are in
Autostop. Customer settings will be maintained
throughout the Auto Stop/Start process.
Possible Reasons The Engine Does Not
Autostop
Prior to engine shut down, the system will check
many safety and comfort conditions for Stop/
Start and ensure they are fulfilled. Detailed
information about the operation of the Stop/
Start system may be viewed in the instrument
cluster display Stop/Start screen. In the
following situations the engine will not stop:
If Stop/Start is manually disabled by the
Stop/Start OFF button.
Driver’s seat belt is not buckled.
Driver’s door is not closed.
Battery temperature is too warm or cold.
Battery charge is low. During this time a
message will display "Stop/Start Not Ready
Battery Charging".
The vehicle is on a steep grade.
Cabin heating or cooling is in process and an
acceptable cabin temperature has not been
achieved.
HVAC is set to full defrost mode at a high
blower speed.
HVAC set to MAX A/C.
Engine has not reached normal operating
temperature.
The transmission is not in a forward gear.
Hood is open.
Brake pedal is not pressed with sufficient

The transmission selector is moved out of
DRIVE.
To maintain cabin temperature comfort.
HVAC is set to full defrost mode.
HVAC system temperature or fan speed is
manually adjusted.
Battery voltage drops too low. During this
time a message will display "Stop/Start Not
Ready Battery Charging".
Low brake vacuum (e.g. after several brake
pedal applications).
Stop/Start OFF switch is pushed.
A Stop/Start system error occurs.
To Manually Turn Off The Stop/Start System

Stop/Start OFF Button
1. Push the Stop/Start OFF switch (located on
the instrument panel). The light on the
switch will illuminate.

2. The “STOP/START OFF” message will appear in the instrument cluster display.
