The driver door has a switch for the
passenger and rear windows as
well. The power windows will work
when the ignition is in ON/RUN or
ACC/ACCESSORY, or when Retained Accessory Power (RAP) is
active. See
Retained Accessory
Power (RAP) on page 9‑32.
Push the switch down to lower the
window, and pull up the front of the

Express-down Windows
Vehicles with the express-down
feature allow the driver and front
passenger windows to be lowered
without holding the switch. Push the
switch down to the second detent,
then release, to activate the
express-down mode. The
express-down mode can be
canceled at any time by pulling up
on the front of the switch. To open
the window partway, push the switch
down to the first detent until the
window is at the desired position.
Window Lockout
o(Window Lockout): If a crew
cab or extended cab vehicle has
power windows, the driver door
power window switch has a lockout
feature. This feature prevents the
rear windows from operating, except
from the driver position. Press the
switch to engage or disengage the
lockout feature. An indicator light on
the switch will come on when the

If the vehicle has roof-rail airbags
for the driver, right front passenger,
and second row outboard
passengers, they are in the ceiling
above the side windows.
{WARNING
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into
that person causing severe injury
or even death. The path of an
inflating airbag must be kept
clear. Do not put anything
between an occupant and an
airbag, and do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering.
Do not use seat accessories that
block the inflation path of a
seat-mounted side impact airbag.
Never secure anything to the roof
of a vehicle with roof-rail airbags
by routing a rope or tie‐down
through any door or window
opening. If you do, the path of an
inflating roof-rail airbag will be
blocked.
When Should an Airbag
Inflate?
Frontal airbags are designed to
inflate in moderate to severe frontal
or near-frontal crashes to help
reduce the potential for severe
injuries mainly to the driver's or right
front passenger's head and chest.
However, they are only designed to
inflate if the impact exceeds a
predetermined deployment
threshold. Deployment thresholds
are used to predict how severe a
crash is likely to be in time for the
airbags to inflate and help restrain
the occupants.
Whether the frontal airbags will or
should deploy is not based on
how fast your vehicle is traveling.
It depends largely on what you hit,
the direction of the impact, and how
quickly your vehicle slows down.

You can lock the doors, turn off the
interior lamps and hazard warning
flashers by using the controls for
those features.
{WARNING
A crash severe enough to inflate
the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation. Additional windshield breakage may
also occur from the right front
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new
parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for your vehicle covers the need
to replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See
Vehicle Data
Recording and Privacy on
page 13‑19 andEvent Data
Recorders on page 13‑20.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.
Airbag On-Off Switch
If one of the switches pictured in the
following illustrations is located in
the glove box, the vehicle has an
airbag on-off switch that you can
use to manually turn on or off the
right front passenger airbag.

Fuel Gauge

Black plate (18,1)Chevrolet Silverado Owner Manual - 2012
5-18 Instruments and Controls
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 5‑23 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.
