126 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. 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
• 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 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 Volts
portable appliances like vacuum cleaners, game consoles
and similar devices.
