80 GETTING TO KNOW YOUR INSTRUMENT PANEL
 HVAC 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, over-
loaded power outlets +12 Volts, 150W, USB ports)
during certain driving conditions (city driving, towing,
frequent stopping).
 Installing options like additional lights, upfitter elec-
trical 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 cleaner's,
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, 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 consecutive trips and
the evaluation of the vehicle and driving pattern did not
help to identify the cause.

WARNING LIGHTS AND MESSAGES

Air Bag Warning Light
This warning light will illuminate to indicate a
fault with the air bag, and will turn on for four
to eight seconds as a bulb check when the
ignition is placed in the ON/RUN or ACC/ON/
RUN position. This light will illuminate with a
single chime when a fault with the air bag has been
detected, it will stay on until the fault is cleared. If the light
is either not on during startup, stays on, or turns on while
driving, have the system inspected at an authorized dealer
as soon as possible.
