NOTE:
Two devices can be plugged in at the same
time, and both ports will provide charging capa-
bilities. Only one port can transfer data to the
system at a time. A pop-up will appear and allow
you to select the device transferring data.
For example, if a device is plugged into the Type
A USB port and another device is plugged into
the Type C USB port, a message will appear and
allow you to select which device to use.

Center Stack USB/AUX Media Hub Rear USB Ports

The third and fourth USB ports are located
behind the center console, above the power
inverter. One of these USBs ports are charge
only.
Applicable to only Uconnect 4C/4C NAV With
8.4-inch Display, and Uconnect 4C NAV With
12-inch Display radios, different scenarios are
listed below when a non-phone device is
plugged into the smaller and larger USB ports, and when a phone device is plugged into the
smaller and larger USB ports:
“A new device is now connected. Previous
connection was lost”.
“(Phone Name) now connected. Previous
connection was lost”.
“Another device is in use through the same
USB port. Please disconnect the first device
to use the second device”.
Plugging in a phone or another USB device may
cause the connection to a previous device to be
lost.
If equipped, your vehicle may also contain a
USB port located on the top tray of the vehicles
center console.
If equipped, two Mini-USB ports (Type C), two
Standard USB ports (Type A), and one AUX port
may be located to the left of the center stack,
just below the climate controls.

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.
NOTE:
In vehicles equipped with Stop/Start, a reduced
voltage may be present during an Autostop.

this display shows the instrument cluster
display messages Ú page 114.

The display always show one of the main
menu item after ignition on.
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.
NOTE:
In vehicles equipped with Stop/Start, an oil
pressure indication of zero is normal during an
Autostop. 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.
7. Temperature Gauge
The pointer shows engine coolant
temperature. The pointer positioned
within the normal range indicates that
the engine cooling system is operating
satisfactorily.
The 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 Ú page 423.
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.

the ON/RUN position.
 The fuel pump symbol points to the
side of the vehicle where the fuel door

The DEF Gauge displays the actual level
of Diesel Exhaust Fluid in the DEF tank.
DEF is required to maintain normal
vehicle operation and emissions compli
-
ance. If something is wrong with the
gauge, a DEF Warning Message or
Malfunction Indicator Light (MIL) will be
displayed Ú page 123.
NOTE:
The gauge may take up to five seconds to
update after adding a gallon or more of
Diesel Exhaust Fluid to the DEF tank. If you
have a fault related to the DEF system, the
gauge may not update to the new level. See
an authorized dealer for service.
The DEF gauge may also not immediately
update after a refill if the temperature of the
DEF fluid is below 12°F (-11°C). The DEF line
heater will possibly warm up the DEF fluid
and allow the gauge to update after a period
of run time. Under very cold conditions, it is
possible that the gauge may not reflect the
new fill level for several drives.
Outside temperature can affect DEF
consumption. In cold conditions, 12°F
(-11°C) and below, the DEF gauge needle
can stay on a fixed position and may not
move for extended periods of time. This is a
normal function of the system.

NOTE:
The DEF tank on these vehicles is designed
with a large amount of full reserve. So the
level sensor will indicate a full reading even
before the tank is completely full. To put it

that’s not represented in the gauge. You may
not see any movement in the reading – even
after driving up to 2,000 miles in some
cases.

INSTRUMENT CLUSTER DISPLAY
Your vehicle will be equipped with an
instrument cluster display, which offers useful
information to the driver. With the ignition in the
OFF mode, opening/closing of a door will
activate the display for viewing, and display the
total miles, or kilometers, in the odometer. Your
instrument cluster display is designed to display
important information about your vehicle’s
systems and features. Using a driver interactive
display located on the instrument panel, your
instrument cluster display can show you how
systems are working and give you warnings
when they are not. The steering wheel mounted
controls allow you to scroll through the main
menus and submenus. You can access the
specific information you want and make
selections and adjustments.

OIL LIFE RESET
Your vehicle is equipped with an engine oil
change indicator system. The “Oil Change
Required” message will display in the
instrument cluster display for five seconds after
a single chime has sounded, to indicate the next
scheduled oil change interval. The engine oil
change indicator system is duty cycle based,
which means the engine oil change interval may
fluctuate, dependent upon your personal
driving style.
Unless reset, this message will continue to
display each time you place the ignition in the
ON/RUN position. To turn off the message
temporarily, push and release the OK or arrow
buttons. To reset the oil change indicator
system (after performing the scheduled
maintenance), refer to the following procedure:
1. Without pressing the brake pedal, push the
ENGINE START/STOP button and place the
ignition in the ON/RUN position (do not
start the engine).

2. Push and release the down arrow button
to scroll downward through the main menu
to “Vehicle Info.”
3. Push and release the right arrow button
to access the ”Oil Life” screen.
4. Push and hold the OK button to reset oil life.
If conditions are met, the gauge and
numeric display will update to show 100%.
If conditions are not met a pop up message
of “To reset oil life engine must be off with
ignition in run” will be displayed (for five
seconds), and the user will remain at the Oil
Life screen.
5. Push and release the up or down
arrow button to exit the submenu screen.
NOTE:
If the indicator message illuminates when you
start the vehicle, the oil change indicator
system did not reset. If necessary, repeat this
procedure.
