WIRELESS CHARGING PAD —
I
F EQUIPPED

Wireless Charging Pad

Your vehicle may be equipped with a 15W 3A Qi
wireless charging pad located below the center
stack. This charging pad is designed to wirelessly
charge your Qi enabled mobile phone. Qi is a
standard that allows wireless charging of your
mobile phone.

Your mobile phone must be designed for Qi wireless
charging. If the phone is not equipped with Qi wireless
charging functionality, an aftermarket sleeve or a
specialized back plate can be purchased from your
mobile phone provider or a local electronics retailer.
Please see your phone’s owner’s manual for further
information.
The wireless charging pad is equipped with an
anti-slip mat to hold your mobile phone in place,
and an LED indicator light.
LED Indicator Status:
NOTE:Using a phone case may interfere with wireless
charging.
No Light: Charging pad is idle or searching for a
device.
Blue Light: Device is detected, and is charging.
Red Light/Flashing: Internal error, or foreign
object is detected.
Important Notes Regarding This Vehicle’s Wireless
Charging Pad:
With a compatible mobile phone placed on the
charging pad, when the ignition is switched to
the OFF position, a phone reminder message
will appear on the instrument cluster to warn
the customer.
Wireless charging is not as fast as when the
phone is connected to a wired charger.
The phone’s protective case must be removed
when placed on the wireless charging pad.
iPhone® 12 (including iPod®) is equipped with
software to protect the device from overheating.
When the software is active, the rate of charge
is slowed down to protect the device.
Phones must always be placed on the wireless
charging pad within the outline shown on the
pad so that its charging parts connect with the
charging coils of the system. Movement of the
phone during charging may prevent or slow the
rate of charge.
Having multiple applications open on the phone
while charging will reduce the charging effi -
ciency, and may even shut down an application
that is actively running (i.e. Apple CarPlay®).
This may also cause the phone to overheat.

Wireless chargers may implement certain methods
to prevent the phone from overheating during
charging such as slowing down the rate of charge.
In certain instances, the device may shut down for a
brief period of time (when the device reaches a
certain temperature). If this happens, it does not
mean there is a fault with the wireless charing pad.
This may just be a protective measure to prevent
damage to the phone.

CAUTION!
The key fob should not be placed on the
charging pad or within 6 inches (15 cm) of it.
Doing so can cause excessive heat buildup and
damage to the fob. Placing the fob in close
proximity of the charging pad blocks the fob from
being detected by the vehicle and prevents the
vehicle from starting.
