If the ignition is turned off while the wipers
are performing wipes due to windshield
washing, the wipers continue to run until
they reach the base of the windshield.
Compass
The vehicle may have a compass display on
the Driver Information Center (DIC). The
compass receives its heading and other
information from the Global Positioning
System (GPS) antenna, Electronic Stability
Control (ESC), and vehicle speed information.
The compass system is designed to operate
for a certain number of miles or degrees of
turn before needing a signal from the GPS
satellites. When the compass display shows
CAL, drive the vehicle for a short distance in
an open area where it can receive a GPS
signal. The compass system will
automatically determine when a GPS signal
is restored and provide a heading again.
Clock
Set the time and date using the
infotainment system. See "Time/Date" under
Settings0182.
Power Outlets
Accessory power outlets can be used to plug
in electrical equipment, such as a cell phone
or MP3 player.
Rear of Front Center Console
The vehicle has one accessory power outlet
under the climate control system and one
accessory power outlet on the rear of the
center console, if equipped, or on the rear of
the bench seat, if equipped.
Lift the cover to access and replace when
not in use.
{Warning
Power is always supplied to the outlets.
Do not leave electrical equipment
plugged in when the vehicle is not in use
because the vehicle could catch fire and
cause injury or death.
Caution
Leaving electrical equipment plugged in
for an extended period of time while the
vehicle is off will drain the battery.
Always unplug electrical equipment when
not in use and do not plug in equipment
that exceeds the maximum 15 amp
rating.
Certain power accessory plugs may not be
compatible with the accessory power outlet
and could overload vehicle or adapter fuses.
If a problem is experienced, see your dealer.
When adding electrical equipment, be sure
to follow the proper installation instructions
included with the equipment. See Add-On
Electrical Equipment 0297.

Caution
Hanging heavy equipment from the
power outlet can cause damage not
covered by the vehicle warranty. The
power outlets are designed for accessory
power plugs only, such as cell phone
charge cords.
Power Outlet 110/120-Volt Alternating
Current
If equipped, the vehicle has two alternating
current power outlets.
In Cab Power Outlet and DC/AC Switch
Truck Bed Power Outlet
When the ignition is on, power is supplied
to the outlets after the DC/AC switch is
pressed. A green indicator light on the DC/
AC switch indicates when the DC/AC
operation is active. One power outlet can be
used with electrical equipment that uses a
maximum of 400 watts. If both outlets are
being used, 400 watts will be shared
between the outlets. Ensure that all
connected devices do not exceed 400 watts.
The power outlet can be turned off by
pressing the DC/AC switch. The power outlet
can be turned back on after 10 seconds,
during which the indicator light on the
switch will flash. An indicator light on the outlet illuminates
when power is provided to the outlet and
no system fault is detected. The outlets will
not operate when the ignition is off, the
DC/AC switch is not pressed, or the plug is
not fully seated into the outlet.
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 turns off.
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
If equipped and enabled, the vehicle has
wireless charging on the center console in
front of the cupholders. 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. SeeRadio
Frequency Statement 0404.
{Warning
Wireless charging may 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, during a Bluetooth phone
call, or when phone projection (e.g. Apple
CarPlay / Android Auto) is active. See
Retained Accessory Power (RAP) 0227. The operating temperature is
−40 °C (−40 °F)
to 85 °C (185 °F) for the charging system and
0 °C (32 °F) to 35 °C (95 °F) for the phone.
A charging stopped alert may be displayed
on the infotainment screen, if the wireless
charger or smartphone are outside of
normal operating temperature. Charging will
automatically resume when a normal
operating temperature is reached.
{Warning
Remove all objects from the charger
before charging your compatible
smartphone. Objects, such as coins, keys,
rings, paper clips, or cards, between the
smartphone and charger may 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 charger, to
prevent burns.
To charge a compatible smartphone:
1. Confirm the smartphone is capable of wireless charging.
2. Remove all objects from the charging pad. The system may not charge if there
are any objects between the smartphone
and charger.
3. Place the smartphone face up against the rear of the charger.
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 charger from working, or reduce the
charging performance. See your dealer
for additional information.

smartphone is overheated. Remove the
smartphone and any objects from the
charger in order to cool the system.
The smartphone may become warm during
charging. This is normal. In warmer
temperatures, the speed of charging may be
reduced.
