When the ignition is on, power to the 110
Volt outlet is enabled after the
-
button is pressed, seeInstrument Panel
Overview 04for button location. A green
indicator light on the button indicates when
the 110 Volt outlet is enabled. 110 Volt
power is supplied to the outlet when it is
enabled and electrical equipment is plugged
into that outlet. One power outlet can be
used with electrical equipment that uses a
maximum of 400 watts. Ensure that all
connected devices do not exceed 400 watts.
The power outlet can be turned off by
pressing the
-button. An indicator light on the outlet illuminates
when the system is enabled and no system
fault is detected. The outlet will not provide
power when the ignition is off, the
-
button is not pressed, or the plug is not
fully seated into the outlet. The outlet does
not operate while the engine is starting. If a
USB powered streaming device is being
used, it is suggested to use a USB Port for
power, see
USB Port0152. If uninterrupted
power supply is required while driving,
disable the auto-stop feature, see Stop/Start
System 0229.
If equipment is connected using more than
400 watts or a system fault is detected, a
protection circuit shuts off the power supply
and the indicator light will flash.
Do not use a power outlet with a missing or
damaged cover.
The power outlet is not designed for the
following, and may not work properly if
they are plugged in:
.Equipment with high initial peak wattage,
such as compressor-driven refrigerators
and electric power tools
.Other equipment requiring an extremely
stable power supply, such as
microcomputer-controlled electric blankets
and touch sensor lamps
.Medical equipment
Wireless Charging
The system operates at 145 kHz and
wirelessly charges one Qi compatible
smartphone. The power output of the
system is capable of charging at a rate up
to 3 amp (15 W), as requested by the
compatible smartphone. See Radio
Frequency Statement 0409.
{Warning
Wireless charging can affect the
operation of an implanted pacemaker or
other medical devices. If you have one, it
is recommended to consult with your
doctor before using the wireless charging
system.
The vehicle must be on, in ACC/ACCESSORY,
or Retained Accessory Power (RAP) must be
active. The wireless charging feature may
not correctly indicate charging when the

0 229.
The operating temperature is −20 °C (−4 °F)
to 60 °C (140 °F) for the charging system
and 0 °C (32 °F) to 35 °C (95 °F) for the
phone.
{Warning
Remove all objects from the charging pad
before charging your compatible
smartphone. Objects, such as coins, keys,
rings, paper clips, or cards, between the
smartphone and charging pad will
become very hot. On the rare occasion
that the charging system does not detect
an object, and the object gets wedged
between the smartphone and charger,
remove the smartphone and allow the
object to cool before removing it from
the charging pad, to prevent burns.
To charge a compatible smartphone:
1. Remove all objects from the charging pad. The system may not charge if there
are any objects between the smartphone
and charging pad.
2. Place the smartphone face up at the bottom edge of the charge pad.
To maximize the charge rate, ensure the
smartphone is fully seated and centered
in the holder with nothing under it.
A thick smartphone case may prevent
the wireless charger from working,
or may reduce the charging performance.
See your dealer for additional
information. 3. A green
}will appear on theVon
the infotainment display. This indicates
that the smartphone is properly
positioned and charging. If a smartphone
is placed on the charging pad and
}
does not display, remove the
smartphone from the pad, turn it
180 degrees, and wait three seconds
before placing/aligning the smartphone
on the pad again.
4. If
}turns yellow, ensure that the
charging pad is clear of any objects and
that the smartphone is capable of
wireless charging before re-positioning it.
If
}does not illuminate, the
smartphone may need to re-positioned.
The smartphone may become warm
during charging. This is normal. In
warmer temperatures, the speed of
charging may be reduced.
