power plugs only, such as cell phone
charge cords.
Wireless Charging
If equipped, the vehicle has a wireless
charging pocket between the driver and
passenger seatbacks. 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 amps (15W), as requested by
the compatible smartphone. SeeRadio
Frequency Statement 0316.
{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 vehicle is in RAP, or during Bluetooth phone
calls. See
Retained Accessory Power (RAP)

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
smartphone. A message may be displayed
on the infotainment display indicating that
the system is unable to charge due to high
temperature while the charger or the phone
is above or below these operating ranges.
{Warning
Remove all objects from the charging
pocket before charging your compatible
smartphone. Objects, such as coins, keys,
rings, paper clips, or cards, between the
smartphone and the charger 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 the
charger, remove the smartphone and
allow the object to cool before removing
it from the charging pocket, to prevent
burns.
To charge a compatible smartphone:
1. Remove all objects from the charging pocket. The system may not charge if
there are any objects between the
smartphone and charging pocket.
2. Place the smartphone with screen facing out of the charging pocket.
Ensure the smartphone is fully seated

A thick smartphone case may prevent
the wireless charger from working,
or may reduce the charging performance.
