Wireless Charging Pad
Your vehicle may be equipped with a 15W 3A Qi
wireless charging pad located inside of the center
console. This charging pad is designed to
wirelessly charge your Qi enabled mobile phone.
Qi is a standard 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 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, an adjustable cradle to hold your

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.

STARTING AND OPERATING125
NOTE:
Engine idle speed will automatically increase
to 1,000 RPM and engage the Variable
Geometry Turbocharger at low coolant
temperatures to improve engine warm-up.
The engine will not automatically crank after
the engine "Wait to Start" telltale goes off if a
door or the hood is ajar.

If the engine stalls, or if the ignition switch is
left ON for more than two minutes after the
“Wait to Start” telltale goes out, reset the
intake air heater by turning the ignition switch
to the OFF position for at least 5 seconds and
then back ON. Repeat steps 1 through 6 of
“Keyless Enter-N-Go Starting Procedure –
Engine Manifold Air Temperature 0°F To 66°F
(–18°C to 19°C).”

EXTREME COLD WEATHER
The Cummins Turbo Diesel engine is equipped
with several features designed to assist cold
weather starting and operation:

The engine block heater is a resistance heater
installed in the water jacket of the engine just
above and behind the oil filter. It requires a 110–115 Volt AC electrical outlet
with a grounded, three-wire extension cord.

NOTE:
The engine block heater cord is a factory
installed option. If your vehicle is not equipped,
heater cords are available from an authorized
Mopar dealer.
A 12 Volt heater built into the fuel filter hous -
ings aid in preventing fuel gelling. It is
controlled by a built-in thermostat.
An intake air heater system both improves
engine starting and reduces the amount of
white smoke generated by a warming engine.
