When the ignition is on, power to 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.
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 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, seeUSB Port0153.
If uninterrupted power supply is required
while driving, disable the auto-stop feature,
see Stop/Start System 0211.
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 0419.
{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 accessory mode,
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)
0212.
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.

Speedometer
The speedometer shows the vehicle speed in
either kilometers per hour (km/h) or miles
per hour (mph).
Odometer
The odometer shows how far the vehicle has
been driven, in either kilometers or miles.
The odometer is always displayed in the
bottom of the Driver Information
Center (DIC).
Trip Odometer
The trip odometer shows how far the
vehicle has been driven since the trip
odometer was last reset.

Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
For vehicles with the Stop/Start system,
when the ignition is on, the tachometer
indicates the vehicle status. When pointing to AUTO STOP, the engine is off but the
vehicle is on and can move. The engine
could auto start at any time. When the
indicator points to OFF, the vehicle is off.
When the engine is on, the tachometer will
indicate the rpm. The tachometer may vary
by several hundred rpm, during Auto Stop
mode, when the engine is shutting off and
restarting.

When the ignition is on, the fuel gauge
indicates the approximate amount of fuel
left in the tank.
There is an arrow near the fuel gauge
pointing to the side of the vehicle the fuel
door is on.
When the indicator nears empty, the low
fuel light comes on. There still is a little fuel
left, but the vehicle should be refueled soon.
The fuel gauge may:
.Take a little more, or less fuel to fill up
than it indicates. For example, the gauge
may have indicated the tank is half full,
but it actually takes a little more, or less
than half the tank's capacity to fill
the tank.
.Moves a little while turning a corner,
speeding up, or braking.
.Takes a few seconds to stabilize after the
ignition is turned on and goes back to
empty when the ignition is turned off.
These are normal conditions, none of which
indicate a problem with the fuel gauge.
Fuel Range
The uplevel instrument cluster has a
estimated fuel range located in the bottom
center of the display. The fuel range is displayed with the approximate distance the
vehicle can be driven without refueling. The
fuel range estimate is based on an average
of the vehicle’s fuel economy over recent
driving history and the amount of fuel
remaining in the fuel tank.
When the estimated fuel range is low, the
range shows LOW and a message may also
display in the Driver Information
Center (DIC).

The engine oil pressure gauge shows the
engine oil pressure in kPa (kilopascals)
or psi (pounds per square inch) when the
engine is running.
Oil pressure can vary with engine speed,
outside temperature, coolant temperature,
and oil viscosity.
On some models, the oil pump will vary
engine oil pressure according to engine
needs. Oil pressure may change quickly as
the engine speed or load varies. This is
normal. If the oil pressure warning light or
Driver Information Center (DIC) message
indicates oil pressure outside the normal
operating range, check the engine oil as
soon as possible.
SeeEngine Oil 0325.
Caution
Lack of proper engine oil maintenance
can damage the engine. Driving with the
engine oil low can also damage the
engine. The repairs would not be covered
by the vehicle warranty. Check the oil
level as soon as possible. Add oil if
required, but if the oil level is within the
operating range and the oil pressure is

still low, have the vehicle serviced.
Always follow the maintenance schedule
for changing engine oil.
If the vehicle has a diesel engine, see the
Duramax diesel supplement.

This gauge measures the temperature of the
vehicle's engine coolant.
While driving under normal operating
conditions, if the needle moves into the red
warning area, the engine is too hot. Pull off
the road, stop the vehicle, and turn off the
engine as soon as possible.

This gauge displays while the vehicle is in
the Tow/Haul driver mode, and the lower
gauges are configured to display four
gauges. The transmission fluid temperature
is also selectable as Left/Right side info. To
change gauge configurations, see “Options”
under Instrument Cluster (Base Level) 0102
or Instrument Cluster (Uplevel) 0104.
The transmission temperature gauge shows
the transmission fluid temperature. If the
gauge is reading in the red area and/or a message appears in the Driver Information
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.
