Jeep WRANGLER 2020 Owner's Manual page 137

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

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 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 inte-
rior lights, overloaded power outlets +12 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.
GETTING TO KNOW YOUR INSTRUMENT PANEL
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 consecu-
tive trips and the evaluation of the vehicle and
driving pattern did not help to identify the
cause.
