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, StabiliTrak/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.

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 110V/120V Alternating
Current
If equipped with this power outlet it can be
used to plug in electrical equipment that
uses a maximum limit of 150 watts.
The power outlet is on the rear of the
center console.An indicator light on the outlet turns on to
show it is in use. The light comes on when
the ignition is on, equipment requiring less
than 150 watts is plugged into the outlet,
and no system fault is detected.
The indicator light does not come on when
the ignition is off or if the equipment is not
fully seated into the outlet.
If equipment is connected using more than
150 watts or a system fault is detected, a
protection circuit shuts off the power supply
and the indicator light turns off. To reset
the circuit, unplug the item and plug it back
in or turn the Retained Accessory Power
(RAP) off and then back on. See
Retained
Accessory Power (RAP) 0199. The power
restarts when equipment using 150 watts or
less is plugged into the outlet and a system
fault is not detected.
The power outlet is not designed for and
may not work properly, if the following 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

charging in the storage bin at the front of
the floor console. 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 (15W), as requested by the
compatible smartphone. See Radio
Frequency Statement 0340.

rings, paper clips, or cards, between the
smartphone and charging pad 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 charger,
remove the smartphone and allow the
object to cool before removing it from
the charging pad, to prevent burns.
To charge a compatible smartphone:
1. Remove all objects from the charging pad. The system may not charge if there
are any objects on the charging pad.
2. Place the smartphone face up on the charging pad.
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 wireless charger from working,
or may reduce the charging performance.
See your dealer for additional
information. 3. The
