The fuel gauge, when the ignition is
on, shows how much fuel the
vehicle has left in the tank.
An arrow on the fuel gauge
indicates the side of the vehicle the
fuel door is on.
The gauge first indicates empty
before the vehicle is out of fuel, and
the vehicle's fuel tank should be
filled soon.
When the fuel tank is low, the FUEL
LEVEL LOW message appears in
the Driver Information Center (DIC).
SeeFuel System Messages on
page 5‑38 for more information. Here are some situations owners
may experience with the fuel gauge.
None of these indicate a problem
with the fuel gauge.
.At the gas station, the fuel pump
shuts off before the gauge
reads full.
.It takes a little more or less fuel
to fill up than the fuel gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
.The gauge goes back to empty
when the ignition is turned off.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.

English
This gauge shows the engine
coolant temperature.
It also provides an indicator of how
hard the vehicle is working. During a
majority of the operation, the gauge
reads 100°C (210°F) or less. If you
are pulling a load or going up hills, it
is normal for the temperature to
fluctuate and approach the 122°C
(250°F) mark. If the gauge reaches
the 125°C (260°F) mark, it indicates
that the cooling system is working
beyond its capacity. See
Engine Overheating on
page 10‑18.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Voltmeter Gauge
When the engine is not running, but
the ignition is on, this gauge shows
the battery's state of charge in
DC volts. When the engine is running, the
gauge shows the condition of the
charging system. The charging
system regulates voltage based on
the state of the battery for improved
fuel economy and battery life. The
gauge may transition from a higher
to lower or a lower to higher
reading, this is normal. Readings
between the low and high warning
zones indicate the normal operating
range. The gauge may also read
low during the fuel economy mode,
this is normal.
Readings in the low warning zone
may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is left
at an idle 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 full
power. If there is a problem with the
battery charging system, this light

checked right away. If the vehicle
must be driven a short distance with
the light on, turn off accessories,
such as the radio and air
conditioner.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors the operation
of the vehicle to ensure emissions
are at acceptable levels, helping to
maintain a clean environment. The
malfunction indicator lamp comes
on when the vehicle is placed in
ON/RUN, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer. See
Ignition Positions on page 9‑22.
If the malfunction indicator lamp
comes on while the engine is
running, this indicates that the OBD
II system has detected a problem
and diagnosis and service might be
required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system also
assists the service technician in
correctly diagnosing any
malfunction.Notice:
If the vehicle is
continually driven with this light
on, the emission controls might
not work as well, the vehicle fuel
economy might not be as good,
and the engine might not run as
smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Notice: Modifications made to the
engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of the
original tires with other than
those of the same Tire
Performance Criteria (TPC) can
affect the vehicle's emission
controls and can cause this light
to come on. Modifications to
these systems could lead to
costly repairs not covered by the
vehicle warranty. This could also
result in a failure to pass a
required Emission Inspection/
Maintenance test. See
Accessories and Modifications on
page 10‑3.

5-20 Instruments and Controls
This light comes on during a
malfunction in one of two ways:
Light Flashing:A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
To prevent more serious damage to
the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the
amount of cargo being hauled as
soon as it is possible.
If the light continues to flash, find a
safe place to stop and park the
vehicle. Turn the vehicle off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and see
your dealer for service as soon as
possible. Light On Steady:
An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
The following may correct an
emission control system
malfunction:
.Check that the fuel cap is fully
installed. See Filling the Tank on
page 9‑60. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration, or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand used.
It may require at least one full tank
of the proper fuel to turn the light off.
See Recommended Fuel on
page 9‑58.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.
Emissions Inspection and
Maintenance Programs
Depending on where you live, your
vehicle may be required to
participate in an emission control
system inspection and maintenance
program. For the inspection, the
emission system test equipment will
likely connect to the vehicle's Data
Link Connector (DLC).

When the Light Is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A Driver Information Center (DIC)
tire pressure message may also
display. SeeTire Messages on
page 5‑42. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the Tire
and Loading Information label. See
Tire Pressure on page 10‑50.
When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the
problem is not corrected, the light
will come on at every ignition cycle.
See Tire Pressure Monitor
Operation on page 10‑52.Engine Oil Pressure Light
Notice: 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.
This light comes on briefly while
starting the engine. If it does not,
have the vehicle serviced by your
dealer. If the system is working
normally the indicator light then
goes off. If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and it might
have some other system problem.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Low Fuel Warning Light
This light, under the fuel gauge,
comes on briefly while the engine is
being started.
This light and a chime come on

Trip Odometer
Press the trip/fuel button until TRIP
displays. This display shows the
current distance traveled in either
kilometers (km) or miles (mi) since
the last reset for the trip odometer.
Pressing the trip odometer reset
stem will also display the trip
odometer.

Black plate (28,1)GMC Yukon/Yukon XL Owner Manual - 2013 - CRC 2nd edition - 8/15/12
5-28 Instruments and Controls
The trip odometer can be reset to
zero by pressing the set/reset
button while the trip odometer is
displayed. You can also reset the
trip odometer while it is displayed by
pressing and holding the trip
odometer reset stem.
The trip odometer has a feature
called the retroactive reset. This can
be used to set the trip odometer to
the number of kilometers (miles)
driven since the ignition was last
turned on. This can be used if the
trip odometer is not reset at the
beginning of the trip.
To use the retroactive reset feature,
press and hold the set/reset button
for at least four seconds. The trip
odometer will display the number of
kilometers (km) or miles (mi) driven
since the ignition was last turned on
and the vehicle was moving. Once
the vehicle begins moving, the trip
odometer will accumulate mileage.
For example, if the vehicle was
driven 8 km (5 mi) before it is started
again, and then the retroactive reset
feature is activated, the display willshow 8 km (5 mi). As the vehicle
begins moving, the display will then
increase to 8.2 km (5.1 mi), 8.4 km
(5.2 mi), etc.
Fuel Range
Press the trip/fuel button until FUEL
RANGE displays. This display
shows the approximate number of
remaining kilometers (km) or
miles (mi) the vehicle can be driven
without refueling. The display will
show LOW if the fuel level is low.
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. This estimate will
change if driving conditions change.
For example, if driving in traffic and
making frequent stops, this display
may read one number, but if the
vehicle is driven on a freeway, the
number may change even though
the same amount of fuel is in the
fuel tank. This is because different
driving conditions produce different
fuel economies. Generally, freeway
driving produces better fuel
economy than city driving. Fuel
range cannot be reset.
Average Economy
Press the trip/fuel button until AVG
ECONOMY displays. This display
shows the approximate average
liters per 100 kilometers (L/100 km)
or miles per gallon (mpg). This
number is calculated based on the
number of L/100 km (mpg) recorded
since the last time this menu item
was reset. To reset AVG
ECONOMY, press and hold the set/
reset button.
Fuel Used
Press the trip/fuel button until FUEL
USED displays. This display shows
the number of liters (L) or
gallons (gal) of fuel used since the
last reset of this menu item. To reset
the fuel used information, press and
hold the set/reset button while FUEL
USED is displayed.
