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 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
Ú
page 123.
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 the charging system. The
charging system is still functioning properly.

Turning on all possible vehicle electrical loads
(e.g. HVAC to max settings, exterior and inte -
rior lights, overloaded power o12 Volt,
150W, USB ports) during certain driving condi -
tions (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 cleaner’s, game consoles
and similar devices.
