2. Find the vehicle's currentlocation and variance zone
number on the map.
Zones 1 through 15 are
available.
3. Press the set/reset button to scroll through and select the
appropriate variance zone. 4. Press the trip/fuel button
until the vehicle heading,
for example, N for North,
is displayed in the DIC.
Or, if the vehicle does not
have DIC buttons, press and
hold the trip odometer reset
stem for two seconds to select
the next available variance
zone. Repeat this step until
the appropriate variance zone
is displayed.
5. If calibration is necessary, calibrate the compass.
See “Compass Calibration
Procedure” following.
Compass Calibration
The compass can be manually
calibrated. Only calibrate the
compass in a magnetically clean
and safe location, such as an open
parking lot, where driving the
vehicle in circles is not a danger. It is suggested to calibrate away
from tall buildings, utility wires,
manhole covers, or other industrial
structures, if possible.
If CAL should ever appear in the
DIC display, the compass should be
calibrated.
If the DIC display does not show a
heading, for example, N for North,
or the heading does not change
after making turns, there may be
a strong magnetic field interfering
with the compass. Such interference
may be caused by a magnetic CB
or cell phone antenna mount, a
magnetic emergency light, magnetic
note pad holder, or any other
magnetic item. Turn off the vehicle,
move the magnetic item, then turn
on the vehicle and calibrate the
compass.

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 9‑49for 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.
When the fuel tank is low the
FUEL LEVEL LOW message
appears. See
Fuel System
Messages
on page 5‑48for
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
For vehicles with an engine oil
pressure gauge, it shows the engine
oil pressure in kPa (kilopascals)
or psi (pounds per square inch)
when the engine is running.

Black plate (20,1)Chevrolet Silverado Owner Manual - 2011
5-20 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 10‑24.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Voltmeter Gauge
For vehicles with a 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.
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.
See
Charging System Light
on
page 5‑26for more information.
The voltmeter gauge may also read
lower when in fuel economy mode.
This is normal.

Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation
of the fuel, ignition, and emission
control systems. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.
This light should come on when the
ignition is on, 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.If the Malfunction Indicator Lamp
comes on and stays on while the
engine is running, this indicates that
there is an OBD II problem and
service is 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 assists
the service technician in correctly
diagnosing any malfunction.
Notice:
If the vehicle is
continually driven with this
light on, after a while, 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.
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.

Black plate (28,1)Chevrolet Silverado Owner Manual - 2011
5-28 Instruments and Controls
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, when
it is safe to do so, stop the vehicle.
Find a safe place to 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. An emission system malfunction
might be corrected:
.Make sure the fuel cap is fully
installed. See
Filling the Tankon
page 9‑88. 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.
.If the vehicle has been driven
through a deep puddle of water,
the vehicle's electrical system
might be wet. The condition
is usually corrected when the
electrical system dries out.
A few driving trips should turn
the light off.
.Make sure to fuel the vehicle
with quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and can
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 will require at
least one full tank of the proper
fuel to turn the light off.
See Recommended Fuel
on
page 9‑84.
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.

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, if the vehicle
is equipped with a radio, comes on
when the fuel tank is low on fuel.
The Driver Information Center also
displays a
“FUEL LEVEL LOW”
message. See Fuel System
Messages
on page 5‑48for more
information. When fuel is added
this light and message should go
off. If it does not, have the vehicle
serviced by your dealer.
