tions on the windshield or camera lens will
cause the system to function improperly.
If the windshield or Automatic High Beam Head -
lamp Control mirror is replaced, the mirror must
be re-aimed to ensure proper performance. See
a local authorized dealer.
To opt out of the Automatic High-Beam Sensi -
tivity Control (default) and enter Reduced

F90 Fuse 20 A Yellow Instrument Panel Power
Outlet Battery Fed (If Equipped)
F91 Fuse 20 A Yellow Instrument Panel Power
Outlet Ignition Fed (If Equipped)
F93 Fuse 20 A Yellow Cigar Lighter/ Instrument
Panel Power Outlet (If Equipped)
When the vehicle is turned off, be sure to unplug
any equipment as to not drain the battery of the
vehicle. All accessories connected to the outlet(s)
should be removed or turned off when the vehicle
is not in use to protect the battery against
discharge.
POWER INVERTER — IF EQUIPPED
If equipped, a 115 Volt (400 Watts maximum)
inverter may be located inside the center console
towards the right hand side, just under the
Wireless Charging Pad (if equipped). This inverter
can power cellular phones, electronics and other
low power devices requiring power up to
400 Watts. Certain video game consoles exceed
this power limit, as will most power tools.
CAUTION!
Do not exceed the maximum power of 160
Watts (13 Amps) at 12 Volts. If the 160 Watts
(13 Amps) power rating is exceeded, the fuse
protecting the system will need to be replaced.
Power outlets are designed for accessory
plugs only. Do not insert any other object in
the power outlets as this will damage the
outlet and blow the fuse. Improper use of the
power outlet can cause damage not covered
by your New Vehicle Limited Warranty.
WARNING!
To avoid serious injury or death:
Only devices designed for use in this type of
outlet should be inserted into any 12 Volt
outlet.
Do not touch with wet hands.
Close the lid when not in use and while driving
the vehicle.
If this outlet is mishandled, it may cause an
electric shock and failure.
CAUTION!

Many accessories that can be plugged in draw
power from the vehicle's battery, even when not
in use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle's battery
will discharge sufficiently to degrade battery life
and/or prevent the engine from starting.

Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these inter -
mittently and with greater caution.

After the use of high power draw accessories,
or long periods of the vehicle not being started
(with accessories still plugged in), the vehicle
must be driven a sufficient length of time to
allow the generator to recharge the vehicle's
battery.

NOTE:
The charging system is independent from load
reduction. The charging system performs a diag-
nostic on the charging system continuously.
If the Battery Charge Warning Light is on it may
indicate a problem with the charging system
Ú page 104.
The electrical loads that may be switched off
(if equipped), and vehicle functions which can be
affected by load reduction:
Heated Seats/Vented Seats/Heated Wheel
Rear Defroster And Heated Mirrors
HVAC System
115 Volt 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 +12 Volts, 115
Volt AC, USB ports) during certain driving condi -
tions (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 Volt 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 exte -
rior).
Check what may be plugged in to power
outlets +12 Volts, 115 Volt 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

driver or passenger seat belt is
unbuckled. When the ignition is first
placed in the ON/RUN or ACC/ON/RUN
position and if the driver’s seat belt is unbuckled,
a chime will sound and the light will turn on. When
driving, if the driver or front passenger seat belt
remains unbuckled, the Seat Belt Reminder Light
will flash or remain on continuously and a chime
will sound Ú page 288.
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 not on during startup, stays on,
or turns on while driving, have the system inspected
at an authorized dealer as soon as possible.

Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake
light turns on it may indicate that the parking brake is applied, that the brake fluid level
is low, or that there is a problem with the Anti-Lock
Brake System reservoir.
If the light remains on when the parking brake has
been disengaged, and the fluid level is at the full
mark on the master cylinder reservoir, it indicates
a possible brake hydraulic system malfunction or
that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS) /
Electronic Stability Control (ESC) system. In this
case, the light will remain on until the condition has
been corrected. If the problem is related to the
brake booster, the ABS pump will run when
applying the brake, and a brake pedal pulsation
may be felt during each stop.
The dual brake system provides a reserve braking
capacity in the event of a failure to a portion of the
hydraulic system. A leak in either half of the dual
brake system is indicated by the Brake Warning
Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a
specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is
necessary.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic Brake
Force Distribution (EBD). In the event of an EBD
failure, the Brake Warning Light will turn on along
with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the OFF
position to the ON/RUN position. The light should
illuminate for approximately two seconds. The light
should then turn off unless the parking brake is
applied or a brake fault is detected. If the light does
not illuminate, have the light inspected by an
authorized dealer.
The light also will turn on when the parking brake
is applied with the ignition switch in the ON/RUN
position.NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake appli
-
cation.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have
failed. It will take longer to stop the vehicle. You
could have a collision. Have the vehicle checked
immediately.
