Ashtrays
The vehicle may have a front
ashtray located near the center of
the instrument panel. Pull on the
door to open it. The ashtray may
have a cigarette lighter.
Notice:If papers, pins, or other
flammable items are put in the
ashtray, hot cigarettes or other
smoking materials could ignite
them and possibly damage the
vehicle. Never put flammable
items in the ashtray.
To remove the ashtray, open the
door and pull the ashtray bin toward
you. To replace the ashtray, insert
the ashtray bin inside the ashtray
door and press down until it
engages.
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to
the warning lights and gauges
could prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working. Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.

For vehicles with a DURAMAX®
Diesel engine, see the DURAMAX®
Diesel Supplement for more
information.
For vehicles with a Hybrid, see
the Hybrid Supplement for more
information.
Speedometer
The speedometer shows the
vehicle speed in both kilometers
per hour (km/h) and miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
Engine Hour Meter Display
The Driver Information Center (DIC)
can also display the number of
hours the engine has run. To display
the engine hours, turn the ignition
off, then press and hold the reset
button for at least four seconds.
The hour meter displays for up to
30 seconds, or until the ignition is
turned on. SeeDriver Information
Center (DIC) on page 5‑33 for more
information.
Trip Odometer
The trip odometer shows how far
the vehicle has been driven since
the trip odometer was last set
to zero.
Press the reset button, located on
the instrument panel cluster next
to the voltmeter, to toggle between
the trip odometer and the regular
odometer. Holding the reset button
for approximately one second while
the trip odometer is displayed will
reset it.
To display the odometer reading
with the ignition off, press the reset
button.
See Driver Information Center (DIC)
on page 5‑33 for more information.

Tachometer
The tachometer displays the
engine speed in revolutions per
minute (rpm). For a description of
how Grade Braking affects vehicle
speed while the Tow/Haul Mode is
activated, seeTow/Haul Mode on
page 9‑51 for more information.
If the vehicle is a hybrid, see
the hybrid supplement for more
information.
Fuel Gauge
Metric
English
When the ignition is on, the fuel
gauge shows about how much
fuel is left in the fuel tank.
An arrow on the fuel gauge
indicates the side of the vehicle
the fuel door is on.
The gauge will first indicate empty
before the vehicle is out of fuel, but
the vehicle's fuel tank should be
filled soon.
Page 164 of 594

Black plate (16,1)GMC Sierra Owner Manual - 2011
5-16 Instruments and Controls
When the fuel tank is low the
FUEL LEVEL LOW message
appears. SeeFuel System
Messages on page 5‑46 for
more information.
Here are some situations owners
can 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 fuel tank's capacity to
fill it.
.The gauge goes back to empty
when the ignition is turned off. If the vehicle has a diesel engine,
see the Duramax diesel supplement
for more information.
If the vehicle is a hybrid, see
the hybrid supplement for more
information.
Engine Oil Pressure
Gauge
Metric
English
The engine oil pressure gauge
shows the engine oil pressure
in kPa (kilopascals) or psi (pounds
per square inch) when the engine is
running.
Page 165 of 594

Black plate (17,1)GMC Sierra Owner Manual - 2011
Instruments and Controls 5-17
Oil pressure can vary with engine
speed, outside temperature and
oil viscosity, but if readings are
outside the normal operating range,
the oil pressure light comes on.
SeeEngine Oil Pressure Light on
page 5‑31 for more information.
A reading outside the normal
operating range can be caused
by a dangerously low oil level or
some other problem causing low
oil pressure. Check the vehicle's
oil as soon as possible. See “OIL
PRESSURE LOW STOP ENGINE”
under Engine Oil Messages on
page 5‑45 andEngine Oil on
page 10‑7.{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 has a diesel engine,
see the Duramax diesel supplement
for more information.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Engine Coolant
Temperature Gauge
Metric
Page 166 of 594
Black plate (18,1)GMC Sierra Owner Manual - 2011
5-18 Instruments and Controls
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 pulling a load or going up
hills, it is normal for the temperature
to fluctuate and go over the 113°C
(235°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 10‑25.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Voltmeter Gauge
This gauge indicates the battery
voltage when the ignition is
turned on.
When the ignition is on, this gauge
indicates the battery voltage.

Instruments and Controls 5-19
When the engine is running, this
gauge shows the condition of the
charging system. The gauge can
transition from a higher to lower or
a lower to higher reading. This is
normal. If the vehicle is operating
outside the normal operating range,
the charging system light comes
on. SeeCharging System Light on
page 5‑24 for more information.
The voltmeter gauge may also read
lower when in fuel economy mode.
This is normal.
Readings outside the normal
operating range can also occur
when a large number of electrical
accessories are operating in
the vehicle and the engine is
left idling 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 maximum
power.
The vehicle can only be driven for a
short time with the readings outside
the normal operating range. If the
vehicle must be driven, turn off all
accessories, such as the radio and
air conditioner.
Readings outside the normal
operating range indicate a possible
problem in the electrical system.
Have the vehicle serviced as soon
as possible.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 flashes for
several seconds, then comes on
solid for several more.
This chime and light sequence
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.
