When the vehicle is placed into reverse gear, a video
display illuminates to display the image generated by the
rear view camera located on the tailgate handle. The auto
dimming feature is also disabled to improve rear view
viewing.
Outside Mirrors
To receive maximum benefit, adjust the outside mirrors to
center on the adjacent lane of traffic with a slight overlap of
the view obtained on the inside mirror.NOTE:
If your vehicle is equipped with illuminated ap-
proach lights under the outside mirrors, they can be turned
off through the instrument cluster display or the Uconnect
display. For further information, refer to “Instrument Clus-
ter Display” in “Getting To Know Your Instrument Panel”
or “Uconnect Settings” in “Multimedia”.
WARNING!
Vehicles and other objects seen in the passenger side
convex mirror will look smaller and farther away than
they really are. Relying too much on your passenger
side convex mirror could cause you to collide with
another vehicle or other object. Use your inside mirror
when judging the size or distance of a vehicle seen in
the passenger side convex mirror. Some vehicles will
not have a convex passenger side mirror.
Driver’s Outside Automatic Dimming Mirror — If
Equipped
The driver ’s outside mirror will automatically adjust for
glare from vehicles behind you. This feature is controlled
by the inside automatic dimming mirror and will automati-
cally adjust for headlight glare when the inside mirror
adjusts.

WARNING! (Continued)
equipped with Keyless Enter-N-Go in the ACC or
ON/RUN mode. Occupants, particularly unattended
children, can become entrapped by the power sun-
roof while operating the power sunroof switch. Such
entrapment may result in serious injury or death.
• In a collision, there is a greater risk of being thrown
from a vehicle with an open sunroof. You could also
be seriously injured or killed. Always fasten your
seat belt properly and make sure all passengers are
also properly secured.
• Do not allow small children to operate the sunroof.
Never allow your fingers, other body parts, or any
object, to project through the sunroof opening. In-
jury may result.
Opening Sunroof
Express
Push the switch rearward and release it within one-half
second and the sunroof will open automatically from any
position. The sunroof will open fully and stop automati-
cally. This is called “Express Open”. During Express Open
operation, any other actuation of the sunroof switch will
stop the sunroof.

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 suffi-
ciently 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 intermit-
tently and with greater caution.
(Continued)
CAUTION! (Continued)
•After the use of high power draw accessories, or long
periods of the vehicle not being started (with acces-
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the generator to
recharge the vehicle’s battery.
Cigar Lighter And Ash Receiver — If Equipped
A removable cigar lighter and ash receiver are available.
For vehicles with a bench seat, the cup holder tray can be
used to hold the ash receiver.
Power Inverter — If Equipped
A 115 or 230 Volt (150 Watts Maximum) outlet is located on
the center stack of the instrument panel, to the right of the
radio. This outlet can power cellular phones, electronics and
other low power devices requiring power up to 150 Watts.
Certain high-end video game consoles will exceed this power
limit, as will most power tools.
The power inverter is designed with built-in overload
protection. If the power rating of 150 Watts is exceeded, the
power inverter will automatically shut down. Once the
electrical device has been removed from the outlet the
inverter should automatically reset.

NOTE:
•The charging system is independent from load reduc-
tion. 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
Instrument 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 Seat/Vented Seats/Heated Wheel
• Heated/Cooled Cup Holders — If Equipped
• 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 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.
