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.

accessory power outlets located
below the climate control system,
or may have one accessory power
outlet and one cigarette lighter.
The cigarette lighter is designed to
fit only in the receptacle closest to
the driver.
There may be another accessory
power outlet in the rear cargo area.
If the vehicle has a floor console,
there is an accessory power outlet
inside the storage bin and one on
the rear of the floor console.
Remove the cover to access and
replace when not in use.

The accessory power outlets are
powered, even when the ignition
is in LOCK/OFF. Continuing to use
power outlets while the ignition is in
LOCK/OFF may cause the vehicle's
battery to run down.
{WARNING
Power is always supplied to the
outlets. Do not leave electrical
equipment plugged in when the
vehicle is not in use because the
vehicle could catch fire and cause
injury or death.Notice:
Leaving electrical
equipment plugged in for an
extended period of time while
the vehicle is off will drain the
battery. Always unplug electrical
equipment when not in use and
do not plug in equipment that
exceeds the maximum 20 ampere
rating.
Certain power accessory plugs
may not be compatible to the
accessory power outlet and could
overload vehicle or adapter fuses.
If a problem is experienced, see
your dealer.
When adding electrical equipment,
be sure to follow the proper
installation instructions included
with the equipment. See Add-On
Electrical Equipment on page 9‑123. Notice:
Hanging heavy
equipment from the power
outlet can cause damage not
covered by the vehicle warranty.
The power outlets are designed
for accessory power plugs only,
such as cell phone charge cords.Cigarette Lighter
To use the cigarette lighter, push
it in all the way, and let go. When it
is ready for use, the lighter pops
back out.
Notice: Holding a cigarette lighter
in while it is heating does not let
the lighter back away from the
heating element when it is hot.
Damage from overheating can
occur to the lighter or heating
element, or a fuse could be
blown. Do not hold a cigarette
lighter in while it is heating.

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

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.

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 5‑32for 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 5‑47and Engine Oilon
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

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.

Instruments and Controls 5-21
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, on
vehicles equipped with a radio,
to remind the 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.
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 overhead
console, flashes for several more
seconds and then comes on solid
for several more.
