Some vehicles may be equipped with a rear cupholder that
consists of two cup wells for rear passenger convenience.Rear Cup WellsElectrical Power Outlets
The auxiliary 12 Volt (13 Amp) power outlet can provide
power for in-cab accessories designed for use with the stan -
dard “cigar lighter” plug. The 12 Volt power outlets and 5
Volt (2.5 Amp) USB Port (Charge Only) have a cap attached
to the outlet indicating “12V DC,” together with either a key
symbol, battery symbol, or USB symbol.
A key symbol indicates that the key must be in the ON/RUN
or ACC positions for the outlet to provide power. The battery
symbol indicates that the outlet is connected to the battery,
and can provide power at all times.
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.

When the vehicle is turned off, be sure to unplug any equip -
ment 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.
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.

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 reduction:

• Heated Seats/Vented Seats/Heated Wheel
• Rear Defroster And Heated Mirrors
• HVAC System
• 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 stop -
ping).
• 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.WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the instru-
ment panel together with a dedicated message and/or
acoustic signal when applicable. These indications are indic -
ative and precautionary and as such must not be considered
as exhaustive. Always refer to the information in this chapter
in the event of a failure indication. All active telltales will
display first if applicable. The system check menu may
appear different based upon equipment options and current
vehicle status. Some telltales are optional and may not
appear.
Red Warning Lights
— Seat Belt Reminder Warning Light
This warning light indicates when the 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.
Refer to “Occupant Restraint Systems” in “Safety” for
further information.

CAUTION!
• When installing the power distribution center cover, it is important to ensure the cover is properly positioned
and fully latched. Failure to do so may allow water to
get into the power distribution center and possibly
result in an electrical system failure.
• When replacing a blown fuse, it is important to useonly a fuse having the correct amperage rating. The use
of a fuse with a rating other than indicated may result
in a dangerous electrical system overload. If a properly
rated fuse continues to blow, it indicates a problem in
the circuit that must be corrected. CAUTION!

Located on the center stack, just below the instrument panel,
is the main media hub. There are four total USB Ports : Two
Mini-USBs (Type C) and two Standard USBs (Type A). There
is also an AUX Port located in the middle of the USB Ports.
All four of the USB Ports include a USB Trident and a numer-
ical value one through three, which indicates that the vehicle
can support three fully-functioning USB Ports at a time. Each
USB Port will support media and charging simultaneously.
NOTE:
• The Type C USB port is the primary media port for the radio. Two devices can be plugged in at the same time and
both ports provide charging capabilities, but only one port
can transfer data to the head unit at a time.
• Both ports share a single data connection. However, the user cannot switch between Type A or Type C. For example, if a device is plugged into the Type A USB port
and another device is plugged into the Type C port, connec
-
tion to the Type A port will be lost. Alternatively, if a device
is plugged into the Type C port and another device is
plugged into the Type A port, the Type C device maintains
primary connection.
