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. SeeRetained
Accessory Power (RAP) 0205. 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 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
See High Voltage Devices and Wiring 0279.
Wireless Charging
If equipped, the vehicle has wireless
charging in the storage bin in 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 0357.
{Warning
Wireless charging can 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. See Retained Accessory
Power (RAP) 0205. The operating temperature is
−20 °C (−4 °F)
to 60 °C (140 °F) for the charging system
and 0 °C (32 °F) to 35 °C (95 °F) for the
smartphone.
{Warning
Remove all objects from the charging pad
before charging your compatible
smartphone. Objects, such as coins, keys,
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.

English Base and Midlevel
Metric Uplevel
English Uplevel
This gauge shows the engine coolant
temperature.
If the pointer moves toward the warning
area at the high end of the gauge, the
engine is too hot.
If the engine coolant has overheated and
the vehicle has been operating under normal
driving conditions, pull off the road, stop the
vehicle, and turn off the engine as soon as
possible. See Engine Overheating 0271.
Voltmeter Gauge
When the ignition is on, this gauge indicates
the battery voltage.
When the engine is running, this gauge
shows the condition of the charging system.
The gauge can transition from a higher to
lower or a lower to higher reading. This is
normal. If the vehicle is operating outside
the normal operating range, the charging
system light comes on. See Charging System
Light 0100.
Readings outside the normal operating
range can also occur when a large number
of electrical accessories are operating in the
vehicle and the engine is left idling for an
extended period. This condition is normal

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
If the airbag readiness light stays on
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)
message may also come on.
Passenger Airbag Status Indicator
The vehicle has a passenger sensing system.
See Passenger Sensing System 055 for
important safety information. The overhead
console has a passenger airbag status
indicator.
When the vehicle is started, the passenger
airbag status indicator will light ON and OFF,
and the symbols for on and off, for several
seconds as a system check. Then, after
several more seconds, the status indicator
will light either ON or OFF, and either the
on or off symbol, to let you know the
status of the front outboard passenger
frontal airbag.
If the word ON, and the on symbol, are lit
on the passenger airbag status indicator, it
means that the front outboard passenger
frontal airbag is allowed to inflate. If the word OFF, and the off symbol, are lit
on the passenger airbag status indicator, it
means that the passenger sensing system
has turned off the front outboard passenger
frontal airbag.
If, after several seconds, both status
indicator lights remain on, or if there are no
lights at all, there may be a problem with
the lights or the passenger sensing system.
See your dealer for service.
{Warning
If the airbag readiness light ever comes
on and stays on, it means that
something may be wrong with the airbag
system. To help avoid injury to yourself
or others, have the vehicle serviced right
away. See
Airbag Readiness Light 098
for more information, including important
safety information.
