•115V 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 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 +12V, 115V AC, USB ports)
during certain driving conditions (city driving, towing,
frequent stopping).
• Installing options like additional lights, upfitter electri-
cal accessories, audio systems, alarms and similar de-
vices.
• 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,
+12V 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 outlets +12V, 115V AC, USB ports
– Check HVAC settings (blower, temperature)
– Check the audio settings (volume)
After a trip:
• Check if any aftermarket equipment was installed (ad-
ditional lights, upfitter electrical accessories, audio sys-
tems, alarms) and review specifications if any (load and
Ignition Off Draw currents).

changed from ignition START or ON/RUN to ignition OFF.
Carefully check the vehicle for fuel leaks in the engine
compartment and on the ground near the engine compart-
ment and fuel tank before resetting the system and starting
the engine.
Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag system could
cause it to fail when you need it. You could be
injured if the air bag system is not there to protect
you. Do not modify the components or wiring, in-
cluding adding any kind of badges or stickers to the
steering wheel hub trim cover or the upper right side
of the instrument panel. Do not modify the front
bumper, vehicle body structure, or add aftermarket
side steps or running boards.
• It is dangerous to try to repair any part of the air bag
system yourself. Be sure to tell anyone who works on
your vehicle that it has an air bag system.
• Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may
not function properly if modifications are made.

SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will influence
when the “Oil Change Required” message is displayed.
Severe Operating Conditions can cause the change oil
message to illuminate as early as 3,500 miles (5,600 km)
since last reset. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
your authorized dealer, the message can be reset by
referring to the steps described under “Instrument Cluster
Display” in “Getting To Know Your Instrument Panel” for
further information.Gasoline Engines:
Under no circumstances should oil change intervals exceed
8,000 miles (13,000 km), twelve months or 350 hours of
engine run time, whichever comes first. The 350 hours of
engine run or idle time is generally only a concern for fleet
customers.
Severe Duty:
Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of
engine run time if the vehicle is operated in a dusty and off
road environment or is operated predominately at idle or
very low engine RPM’s. This type of vehicle use is consid-
ered Severe Duty.
Once A Month Or Before A Long Trip:
•
Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and automatic transmis-
sion, and fill as needed
• Check function of all interior and exterior lights
