Battery Saver On/Battery Saver Mode Message —
Electrical Load Reduction Actions — If Equipped
This vehicle is equipped with an Intelligent Battery Sensor
(IBS) to perform additional monitoring of the electrical
system and status of the vehicle battery.
In cases when the IBS detects charging system failure, or the
vehicle battery conditions are deteriorating, electrical load
reduction actions will take place to extend the driving time
and distance of the vehicle. This is done by reducing power
to or turning off non-essential electrical loads.
Load reduction is only active when the engine is running. It
will display a message if there is a risk of battery depletion to
the point where the vehicle may stall due to lack of electrical
supply, or will not restart after the current drive cycle.
When load reduction is activated, the message “Battery
Saver On Some Systems May Have Reduced Power” will
appear in the instrument cluster.
These messages indicate the vehicle battery has a low state of
charge and continues to lose electrical charge at a rate that
the charging system cannot sustain.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 “Getting To Know Your Instru -
ment Panel” for further information.
The electrical loads that may be switched off (if equipped),
and vehicle functions which can be affected by load reduc -
tion:
• Heated Seats/Vented Seats/Heated Wheel
• Rear Defroster And Heated Mirrors
• HVAC System
• 115V AC Power Inverter System
• Audio and Telematics System

GETTING TO KNOW YOUR INSTRUMENT PANEL 145
Loss of the battery charge may indicate one or more of the
following conditions:
• The charging system cannot deliver enough electricalpower 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 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, +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 (addi -
tional 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.

— Vehicle Security Warning Light — If Equipped
This light will flash at a fast rate for approximately 15
seconds when the vehicle security alarm is arming, and then
will flash slowly until the vehicle is disarmed.
— Engine Coolant Temperature Warning Light
This warning light warns of an overheated engine condition.
If the engine coolant temperature is too high, this indicator
will illuminate and a single chime will sound. If the tempera -
ture reaches the upper limit, a continuous chime will sound
for four minutes or until the engine is able to cool: whichever
comes first.
If the light turns on while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift the
transmission into NEUTRAL and idle the vehicle. If the
temperature reading does not return to normal, turn the
engine off immediately and call for service.
Refer to “If Your Engine Overheats” in “In Case Of Emer -
gency” for further information. — Battery Charge Warning Light
This warning light will illuminate when the battery is not
charging properly. If it stays on while the engine is running,
there may be a malfunction with the charging system.
Contact an authorized dealer as soon as possible.
This indicates a possible problem with the electrical system
or a related component.
— Oil Pressure Warning Light
This warning light will illuminate to indicate low engine oil
pressure. If the light turns on while driving, stop the vehicle,
shut off the engine as soon as possible, and contact an autho -
rized dealer. A chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected. This
light does not indicate how much oil is in the engine. The
engine oil level must be checked under the hood.
— Oil Temperature Warning Light
This warning light will illuminate to indicate the engine oil
temperature is high. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. Wait
for oil temperature to return to normal levels.

Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to access
this information to assist with the diagnosis and service of
your vehicle and emissions system.
For further information, refer to “Cybersecurity” in “Multi-
media”.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle's emissions control system. Failure
to pass could prevent vehicle registration.
For states that require an Inspection and Mainte -
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not on
when the engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a depleted battery or a battery replace -
ment. If the OBD II system should be determined not ready
for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle's OBD II system is ready, you must do the following:
1. Cycle the ignition switch to the ON position, but do not crank or start the engine.
WARNING!
• ONLY an authorized service technician should connect equipment to the OBD II connection port in order to
read the VIN, diagnose, or service your vehicle.
• If unauthorized equipment is connected to the OBD II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.

• Access, or allow others to access, information stored in your vehicle systems, including personal information.

NOTE:
If you crank or start the engine, you will have to start this test
over.
2. As soon as you cycle the ignition switch to the ON posi-
tion, you will see the “Malfunction Indicator Light (MIL)”
symbol come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:

• The MIL will flash for about ten seconds and then return to being fully illuminated until you turn OFF the ignition or
start the engine. This means that your vehicle's OBD II
system is not ready and you should not proceed to the I/M
station.

• The MIL will not flash at all and will remain fully illumi -
nated until you place the ignition in the off position or start
the engine. This means that your vehicle's OBD II system
is ready and you can proceed to the I/M station. If your OBD II system is
not ready, you should see an autho -
rized dealer or repair facility. If your vehicle was recently
serviced or had a battery failure or replacement, you may
need to do nothing more than drive your vehicle as you
normally would in order for your OBD II system to update.
A recheck with the above test routine may then indicate that
the system is now ready.
Regardless of whether your vehicle's OBD II system is ready
or not, if the MIL is illuminated during normal vehicle oper -
ation you should have your vehicle serviced before going to
the I/M station. The I/M station can fail your vehicle
because the MIL is on with the engine running.
