116 GETTING TO KNOW YOUR INSTRUMENT PANEL
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.
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 diag-
nostic on the charging system continuously.

If the Battery Charge Warning Light is on it may
indicate a problem with the charging system
Ú
page 118.
The 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

Rear Defroster And Heated Mirrors

HVAC System

115 Volt 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
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 interior
lights, overloaded power o12 Volt,
115 Volt AC, USB ports) during certain driving
conditions (city driving, towing, frequent
stopping, etc.).

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 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
o12 Volt, 115 Volt AC, 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 if the evaluation and driving pattern of
the vehicle did not help to identify the cause.
