Wireless Charging Pad — If Equipped
Wireless Charging PadYour vehicle may be equipped with a 15W 3A Qi wireless
charging pad located inside of the center console just below
the CD player (if equipped). This charging pad is designed to
wirelessly charge your Qi enabled mobile phone. Qi is a stan
-
dard that uses magnetic induction to transfer power to your
mobile device.
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 an 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,
an adjustable cradle to hold your mobile phone in place and
an LED indicator light.
WARNING!
To avoid serious injury or death:
• Do not insert any objects into the receptacles.
• Do not touch with wet hands.
• Close the lid when not in use.
• If this outlet is mishandled, it may cause an electric shock and failure.
CAUTION!
The key fob should not be placed on the charging pad or
within 15 cm (150 mm) 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.
