 Heated Seat/Vented Seats/Heated Wheel
 Heated/Cooled Cup Holders — If Equipped
 Rear Defroster And Heated Mirrors
 HVAC System
 115 Volts 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 the charging
system. The charging system is still functioning prop -
erly.
 Turning on all possible vehicle electrical loads
(e.g. HVAC to max settings, exterior and interior lights,
overloaded power outlets +12 Volts, 115 Volts AC, 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 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
+12 Volts, 115 Volts AC, 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
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated message
and/or acoustic signal when applicable. These indications
are indicative and precautionary and as such must not be
considered as exhaustive and/or alternative to the

70GETTING TO KNOW YOUR INSTRUMENT PANEL
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have 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
Úpage 106.
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
Maintenance (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 dead battery or a battery
replacement. 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.

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 position, 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 10 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 illu -
minated until you place the ignition in the off posi -
tion 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
authorized 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 previously mentioned 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
operation 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.
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.

78STARTING AND OPERATING
(Continued)
(Continued)
AUTOMATIC TRANSMISSION —
IF EQUIPPED
You must press and hold the brake pedal while shifting out
of PARK.
IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF position. This helps the
driver avoid inadvertently leaving the vehicle without
placing the transmission in PARK. This system also locks
the transmission in PARK whenever the ignition is in the
OFF position.
NOTE:The transmission is NOT locked in PARK when the ignition
is in the ACC position (even though the engine will be off).
Ensure that the transmission is in PARK, and the ignition
is
OFF (not in ACC position) before exiting the vehicle.
WARNING!
Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
 Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the trans -
mission gear selector out of PARK with the brake
pedal released. Make sure the transmission is in
PARK before exiting the vehicle.
 The transmission may not engage PARK if the vehicle
is moving. Always bring the vehicle to a complete
stop before shifting to PARK, and verify that the
transmission gear position indicator solidly indicates
PARK (P) without blinking. Ensure that the vehicle is
completely stopped, and the PARK position is prop -
erly indicated, before exiting the vehicle.
 It is dangerous to shift out of PARK or NEUTRAL if the
engine speed is higher than idle speed. If your foot is
not firmly pressing the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You could
lose control of the vehicle and hit someone or some -
thing. Only shift into gear when the engine is idling
normally and your foot is firmly pressing the brake
pedal.
 Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always come to a
complete stop, then apply the parking brake, shift
the transmission into PARK, and turn the ignition
OFF. When the ignition is in the OFF position, the
transmission is locked in PARK, securing the vehicle
against unwanted movement.
 When exiting the vehicle, always make sure the igni -
tion is in the OFF position, remove the key fob from
the vehicle, and lock the vehicle.
 Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be seri -
ously or fatally injured. Children should be warned
not to touch the parking brake, brake pedal or the
transmission gear selector.
WARNING!
 Do not leave the key fob in or near the vehicle (or in
a location accessible to children), and do not leave
the ignition in the ACC or ON/RUN position. A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
 Do not shift between PARK, REVERSE, NEUTRAL, or
DRIVE when the engine is above idle speed.
 Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal.
WARNING!
