Fuel Gauge
Metric
EnglishThe 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). See
Fuel System
Messages on page 5‑42 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.

Engine Oil Pressure
Gauge
Metric
English
The oil pressure gauge shows the
engine oil pressure in psi (pounds
per square inch) when the engine is
running. Canadian vehicles indicate
pressure in kPa (kilopascals). Oil pressure may vary with engine
speed, outside temperature and oil
viscosity, but readings above the
low pressure zone indicate the
normal operating range. When
the oil pressure reaches the low
pressure zone, the OIL PRESSURE
LOW STOP ENGINE message
appears in the Driver Information
Center (DIC). See
Engine Oil
Messages on page 5‑41 and
Engine Oil on page 10‑7 for more
information.

Black plate (16,1)GMC Yukon/Yukon XL Owner Manual - 2011
5-16 Instruments and Controls
A reading in the low pressure zone
may be caused by a dangerously
low oil level or some other problem
causing low oil pressure. Check the
oil as soon as possible.
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Engine Coolant
Temperature Gauge
Metric
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.

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, thislight will come on or the SERVICE
BATTERY CHARGING SYSTEM
DIC message will display. See
Battery Voltage and Charging
Messages on page 5‑38
and
Charging System Light on
page 5‑20 for more information.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
When the engine is started, a
chime sounds for several seconds
to remind a driver to fasten the
safety belt, unless the driver safety
belt is already buckled.
The safety belt light comes on and
stays on for several seconds, then
flashes for several more.

This chime and light are repeated if
the driver remains unbuckled and
the vehicle is in motion. If the driver
safety belt is already buckled,
neither the chime nor the light
comes on.
Passenger Safety Belt
Reminder Light
For vehicles equipped with the
passenger safety belt reminder
light, several seconds after the
engine is started, a chime sounds
for several seconds to remind the
front passenger to buckle their
safety belt. The passenger safety
belt light, located on the instrument
panel, comes on and stays on for
several seconds and then flashes
for several more.
This chime and light are repeated if
the passenger remains unbuckled
and the vehicle is in motion.
If the passenger safety belt is
buckled, neither the chime nor the
light comes on.
The front passenger safety belt
warning light and chime may turn on
if an object is put on the seat such
as a briefcase, handbag, grocery
bag, laptop or other electronic
device. To turn off the warning light
and or chime, remove the object
from the seat or buckle the
safety belt.
Airbag Readiness Light
The system checks the airbag's
electrical system for possible
malfunctions. If the light stays on
it indicates there is an electrical
problem. The system check
includes the airbag sensor, the
pretensioners, the airbag modules,
the wiring, and the crash sensing
and diagnostic module. For more
information on the airbag system,
seeAirbag System on page 3‑39.
The airbag readiness light comes on
solid for a few seconds when the
engine is started. If the light does
not come on then, have it fixed
immediately.

{WARNING
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.
If there is a problem with the airbag
system, a Driver Information Center
(DIC) message can also come on.
See Airbag System Messages on
page 5‑45 for more information.
Passenger Airbag Status
Indicator
If the vehicle has the airbag status
indicator pictured in the following
illustration, then the vehicle has a
passenger sensing system for the
right front passenger position. The
passenger airbag status indicator
is on the overhead console. See
Passenger Sensing System on
page 3‑47for important safety
information.
In addition, if the vehicle has a
passenger sensing system for the
right front passenger position, the
label on the vehicle's sun visors
refers to “ADVANCED AIRBAGS.”
United States
Canada
When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the
symbols for on and off, for several
seconds as a system check. If you
are using remote start, if equipped,
to start the vehicle from a distance,
you may not see the system check.

Black plate (20,1)GMC Yukon/Yukon XL Owner Manual - 2011
5-20 Instruments and Controls
Then, after several more seconds,
the status indicator will light either
ON or OFF, or either the on or off
symbol to let you know the status of
the right front passenger frontal
airbag.
If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the right
front passenger frontal airbag is
enabled (may inflate).
If the word OFF or the off symbol is
lit on the airbag status indicator, it
means that the passenger sensing
system has turned off the right front
passenger frontal airbag.
If, after several seconds, both
status indicator lights remain on,
or if there are no lights at all, there
may be a problem with the lights
or the passenger sensing system.
See your dealer for service.{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light on page 5‑18 for more
information, including important
safety information.
Charging System Light
This light comes on briefly when
the ignition key is turned to START,
but the engine is not running, as a
check to show it is working. If it does not, have the vehicle
serviced by your dealer.
The light should go out once
the engine starts. If it stays on,
or comes on while driving, there
could be a problem with the
charging system. A charging
system message in the Driver
Information Center (DIC) can
also appear. See
Battery Voltage
and Charging Messages on
page 5‑38 for more information.
This light could indicate that there
are problems with a generator drive
belt, or that there is an electrical
problem. Have it 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.
