102 Instruments and Controls
Power Outlet 110/120 Volt Alternating
Current
If equipped, the vehicle has two alternating
current power outlets. One on the back of
the center console and one in the rear of
the vehicle.
When the ignition is on, power to the 110
Volt outlet is enabled after the
-
button is pressed, seeInstrument Panel
Overview 04for button location. A green
indicator light on the button indicates when
the 110 Volt outlet is enabled. 110 Volt
power is supplied to the outlet when it is
enabled and electrical equipment is plugged
into that outlet. One power outlet can be used with electrical equipment that uses a
maximum of 400 watts. Ensure that all
connected devices do not exceed 400 watts.
The power outlet can be turned off by
pressing the
-button.
An indicator light on the outlet illuminates
when the system is enabled and no system
fault is detected. The outlet will not provide
power when the ignition is off, the
-
button is not pressed, or the plug is not
fully seated into the outlet. The outlet does
not operate while the engine is starting. If a
USB powered streaming device is being
used, it is suggested to use a USB Port for
power, see USB Port0155. If uninterrupted
power supply is required while driving,
disable the auto-stop feature, see Stop/Start
System 0208.
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 will flash.
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 in the bin below the
climate control system. 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. See
Radio
Frequency Statement 0398.

Center (DIC), the vehicle must be stopped
and the cause checked. One possible cause is
a low fluid level in the transmission.
Caution
Do not drive the vehicle while the
transmission fluid is overheating, or the
transmission can be damaged. This could
lead to costly repairs that would not be
covered by the warranty.
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 chargingsystem light comes on. See
Charging System
Light 0113. The voltmeter gauge may also
read lower when in fuel economy mode.
This is normal.
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
since the charging system is not able to
provide full power at engine idle. As engine
speeds are increased, this condition should
correct itself as higher engine speeds allow
the charging system to create maximum
power.
The vehicle can only be driven for a short
time with the readings outside the normal
operating range. If the vehicle must be
driven, turn off all accessories, such as the
radio and air conditioner.
Readings outside the normal operating
range indicate a possible problem in the
electrical system. Have the vehicle serviced
as soon as possible.
Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a driver seat belt reminder light on
the instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to remind
the driver to fasten their seat belt.
Then the light stays on solid until the belt is
buckled. This cycle may continue several
times if the 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 066.

If a short distance must be driven with the
light on, be sure to turn off all accessories,
such as the radio and air conditioner. Find a
safe place to stop the vehicle.
Malfunction Indicator Lamp
(Check Engine Light)
This light is part of the vehicle’s emission
control on-board diagnostic system. If this
light is on while the engine is running, a
malfunction has been detected and the
vehicle may require service. The light should
come on to show that it is working when
the ignition is in Service Mode. SeeIgnition
Positions 0205.
Malfunctions are often indicated by the
system before any problem is noticeable.
Being aware of the light and seeking service
promptly when it comes on may prevent
damage.
Caution
If the vehicle is driven continually with
this light on, the emission control system
may not work as well, the fuel economy
may be lower, and the vehicle may not
run smoothly. This could lead to costly
repairs that might not be covered by the
vehicle warranty.
Caution
Modifications to the engine, transmission,
exhaust, intake, or fuel system, or the
use of replacement tires that do not
meet the original tire specifications, can
cause this light to come on. This could
lead to costly repairs not covered by the
vehicle warranty. This could also affect
the vehicle’s ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications 0296.
If the light is flashing : A malfunction has
been detected that could damage the
emission control system and increase vehicle
emissions. Diagnosis and service may be
required. To help prevent damage, reduce vehicle
speed and avoid hard accelerations and
uphill grades. If towing a trailer, reduce the
amount of cargo being hauled as soon as
possible.
If the light continues to flash, find a safe
place to park. Turn the vehicle off and wait
at least 10 seconds before restarting the
engine. If the light is still flashing, follow
the previous guidelines and see your dealer
for service as soon as possible.
If the light is on steady :
A malfunction has
been detected. Diagnosis and service may be
required.
Check the following:
.If fuel has been added to the vehicle
using the capless fuel funnel adapter,
make sure that it has been removed. See
“Filling the Tank with a Portable Gas Can”
under Filling the Tank 0265. The
diagnostic system can detect if the
adapter has been left installed in the
vehicle, allowing fuel to evaporate into
the atmosphere. A few driving trips with
the adapter removed may turn off the
light.
.Poor fuel quality can cause inefficient
engine operation and poor driveability,
which may go away once the engine is
