106 GETTING TO KNOW YOUR INSTRUMENT PANEL
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 108.
The electrical loads that may be switched off
(if equipped), and vehicle functions which can
be affected by load reduction:
Heated Seats/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 capa-
bility 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, 115 Volt AC, 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 exterior).

Check what may be plugged in to power

outlets +12 Volts, 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 the evaluation of the vehicle and driving
pattern did not help to identify the cause.
