An auxiliary power outlet can be found in the
tray on top of the center stack. This power outlet
works when the ignition is in the ON/RUN, ACC,
or OFF position.

Power Outlet — Top Of Center Stack

Power Outlet Fuse Locations:
F104 Fuse 20 A Yellow UCI Port/ USB Rear
Center Console
F90 Fuse 20 A Yellow Instrument Panel
Power Outlet Battery Fed (If Equipped)
F91 Fuse 20 A Yellow Instrument Panel
Power Outlet Ignition Fed (If Equipped)
F93 Fuse 20 A Yellow Cigar Lighter/ Instru -
ment Panel Power Outlet (If Equipped) When the vehicle is turned off, be sure to
unplug any equipment as to not drain the
battery of the vehicle. All accessories connected
to the outlet(s) should be removed or turned off
when the vehicle is not in use to protect the
battery against discharge.
WARNING!
To avoid serious injury or death:
Only devices designed for use in this type of
outlet should be inserted into any 12 Volt
outlet.
Do not touch with wet hands.
Close the lid when not in use and while
driving the vehicle.
If this outlet is mishandled, it may cause an
electric shock and failure.
CAUTION!
Many accessories that can be plugged in
draw power from the vehicle's battery, even
when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the
vehicle's battery will discharge sufficiently
to degrade battery life and/or prevent the
engine from starting.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.), will
discharge the battery even more quickly.
Only use these intermittently and with
greater caution.
After the use of high power draw accesso
-
ries, or long periods of the vehicle not being
started (with accessories still plugged in),
the vehicle must be driven a sufficient
length of time to allow the generator to
recharge the vehicle's battery.

Power Inverter — If Equipped
If equipped, a 115 Volt (400 Watts Maximum)
inverter may be located inside the center
console towards the right hand side, just under
the Wireless Charging Pad (if equipped). This
inverter can power cellular phones, electronics
and other low power devices requiring power up
to 400 Watts. Certain high-end video game
consoles exceed this power limit, as will most
power tools.

Center Console Power Inverter Outlet

There is also a second 115 Volt (400 Watts
Maximum) power inverter located on the rear of
the center console. This inverter can power
cellular phones, electronics and other low
power devices requiring power up to 400 Watts.
Certain high-end video game consoles exceed
this power limit, as will most power tools. All power inverters are designed with built-in
overload protection. If the power rating of 400
Watts is exceeded, the power inverter shuts
down. Once the electrical device has been
removed from the outlet the inverter should
reset.

Rear Center Console Power Inverter Outlet

NOTE:

400 Watts is the maximum for the inverter, not
each outlet. If three outlets are in use, 400 Watts
is shared amongst the devices plugged in.

If equipped, there may be a 115 Volt
(400 Watts Maximum) inverter located to the
right of the center stack, just below the climate
controls. This inverter can power cellular phones, electronics and other low power
devices requiring power up to 400 Watts.
Certain high-end video game consoles exceed
this power limit, as will most power tools.

Center Stack Power Inverter

To turn on the power outlet, simply plug in the
device. The outlet turns off when the device is
unplugged.
NOTE:
The Power Inverter only turns on if the igni -
tion is in the ACC or ON/RUN position.
Due to built-in overload protection, the power
inverter shuts down if the power rating is
exceeded.

Wireless Charging Pad — If Equipped

Wireless Charging Pad

Your vehicle may be equipped with a 15W 3A Qi
wireless charging pad located inside of the
center console just below the CD player (if
equipped). This charging pad is designed to wirelessly charge your Qi enabled mobile
phone. Qi is a standard that uses magnetic
induction to transfer power to your mobile
device.
Your mobile phone must be designed for Qi
wireless charging. If the phone is not equipped
with Qi wireless charging functionality, an after
-
market sleeve or a specialized back plate can
be purchased from your mobile phone provider
or an local electronics retailer. Please see your
phone’s owner’s manual for further informa -
tion.
The wireless charging pad is equipped with an
anti-slip mat, an adjustable cradle to hold your
mobile phone in place and an LED indicator
light.
Overhead Sunglass Storage
At the front of the overhead console, a compart -
ment is provided for the storage of one pair of
sunglasses.
From the closed position, push the door latch to
open the compartment.

Overhead Sunglass Door

The door will slowly rotate to the full open posi -
tion.WARNING!
To avoid serious injury or death:
Do not insert any objects into the recepta -
cles.
Do not touch with wet hands.
Close the lid when not in use.
If this outlet is mishandled, it may cause an
electric shock and failure.
CAUTION!
The key fob should not be placed on the
charging pad or within 15 cm (150 mm) of it.
Doing so can cause excessive heat buildup
and damage to the fob. Placing the fob in
close proximity of the charging pad blocks the
fob from being detected by the vehicle and
prevents the vehicle from starting.

Base / Midline Instrument Cluster
Descriptions

1. Tachometer

Indicates the engine speed in revolutions
per minute (RPM x 1000).
2. Voltmeter
When the vehicle is in the RUN state, the gauge indicates the electrical system
voltage. The pointer should stay within
the normal range if the battery is
charged. If the pointer moves to either
extreme left or right and remains there
during normal driving, the electrical
system should be serviced. 3. Instrument Cluster Display
When the appropriate conditions exist,
this display shows the instrument cluster
display messages. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further informa -
tion. 4. Oil Pressure GaugeThe pointer should always indicate the oil
pressure when the engine is running. A
continuous high or low reading under
normal driving conditions may indicate a
lubrication system malfunction. Imme -
diate service should be obtained from an
authorized dealer.
5. Speedometer
Indicates vehicle speed.

6. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the ignition is in the ON/
RUN position.
 The fuel pump symbol points
to the side of the vehicle where
the fuel door is located.
Refer to “Refueling The Vehicle — Gas
Engine” in “Starting And Operating” for
further information. 7. Temperature Gauge
The gauge pointer shows engine coolant
temperature. The pointer positioned
within the normal range indicates that
the engine cooling system is operating
satisfactorily.
The gauge pointer will likely indicate a higher temperature when driving in hot
weather, up mountain grades, or when
towing a trailer. It should not be allowed
to exceed the upper limits of the normal
operating range.
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by steam
or boiling coolant. You may want to call an
authorized dealer for service if your vehicle
overheats. If you decide to look under the
hood yourself, see “Servicing And
Maintenance.” Follow the warnings under the
Cooling System Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the
temperature gauge reads “H,” pull over and
stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on the “H,” turn the engine off
immediately and call an authorized dealer for
service.
