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

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 0413.
{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) 0220. 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.

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.
4. A green
]will appear on the
infotainment display, next to the phone
icon. This indicates that the smartphone
is detected.
5. If a smartphone is placed on the charger and
]turns off or turns yellow, remove
the smartphone and any objects from
the pad. Turn the smartphone
180 degrees and wait a few seconds
before placing/aligning it on the pad
again.
6. If a smartphone is placed on the charger and
]turns red, the charger and/or the
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. Software Acknowledgements

power.
The vehicle can only be driven for a short
time with the readings outside the normal

driver remains or becomes unbuckled while
the vehicle is moving.
If the driver seat belt is buckled, neither the
light nor the chime comes on.
Front Passenger Seat Belt Reminder
Light
The vehicle may have a front passenger seat
belt reminder light near the passenger
airbag status indicator.
See Passenger Sensing System 069.
When the vehicle is started, this light
flashes and a chime may come on to remind
passengers to fasten their seat belt. Then
the light stays on solid until the belt is
buckled. This cycle continues several times if
the front passenger remains or becomes
unbuckled while the vehicle is moving.
If the front passenger seat belt is buckled,
neither the chime nor the light comes on.
The front passenger seat belt reminder light
and chime may turn on if an object is put

When the vehicle is started, these lights
come on solid to remind rear passengers to
fasten their seat belts. Then each light may
stay on solid or flash, and a chime may
come on if the rear passenger remains
unbuckled, or becomes unbuckled, when the
vehicle is moving. An X indicates the seat
belt is not buckled. A check mark indicates
the seat belt is buckled.
If all rear seat positions are buckled, neither
the chime nor the lights will come on.
For information on the front seat belt
reminder lights, see "Driver Seat Belt
Reminder Light" and "Front Passenger Seat
Belt Reminder Light" listed previously.

module. For more information on the airbag
system, seeAirbag System 064.
The airbag readiness light comes on for
several seconds when the vehicle is started.
If the light does not come on then, have it
fixed immediately.
{Warning

after the vehicle is started or comes on
while driving, it means the airbag system
might not be working properly. The
airbags in the vehicle might not inflate in
a crash, or they could even inflate
without a crash. To help avoid injury,
have the vehicle serviced right away.
If there is a problem with the airbag
system, a Driver Information Center (DIC)
