instrument panel CHEVROLET SILVERADO 2003 1.G User Guide

·Your vehicle is equipped with electronic frontal
sensors which help the sensing system distinguish
between a moderate and a more severe frontal
impact. Your vehicle is also equipped with a crash
sensing and diagnostic module, which records
information about the frontal air bag system. The
module records information about the readiness of
the system and when the system commands air bag
in¯ation. It records the status of the driver's safety
belt usage in a crash in which the air bag deploys or
a crash in which the air bag nearly deploys. The
module also records speed, engine rpm, brake and
throttle data.
·Let only quali®ed technicians work on your air bag
systems. Improper service can mean that an air bag
system will not work properly. See your dealer for
service.
Notice:If you damage the covering for the driver's
or the right front passenger's air bag, the bag
may not work properly. You may have to replace the
air bag module in the steering wheel or both the
air bag module and the instrument panel for
the right front passenger's air bag. Do not open or
break the air bag coverings.
Air Bag Off Switch
Regular Cab and Extended Cab Models
If your vehicle is a regular cab model or an extended cab
model, it has a switch on the instrument panel that you
can use to turn off the right front passenger's air bag.
United States with Passenger Sensing System

To turn the right front passenger's air bag on again,
insert your ignition key into the switch, push in,
and move the switch to the ON or AUTO position.
Passenger Sensing System
If your rearview mirror has one of the indicators pictured
in the following illustrations, your vehicle has a passenger
sensing system. The indicator will be visible when you
turn your ignition key to RUN or START. The words ON
and OFF or the symbol for on and off, will be visible on
the rearview mirror during the system check. When the
system check is complete, either the word ON or the word
OFF, or the symbol for on or the symbol for off will be
visible. See
Passenger Air Bag Status Indicator on
page 3-40. If your rearview mirror does not have either of
the indicators pictured below, then your vehicle does not
have the passenger sensing system.The passenger sensing system will turn off the right
front passenger's frontal air bag under certain
conditions. The driver's air bag and the side air bags
are not part of the passenger sensing system. In
addition to the passenger sensing system, your vehicle
also has an air bag off switch located on the instrument
panel as required by the government.
The passenger sensing system works with sensors that
are part of the right front passenger's seat and safety
belt. The sensors are designed to detect the presence of
a properly seated occupant and determine if the
passenger's frontal air bag should be enabled (may
in¯ate) or not.

{CAUTION:
If the air bag readiness light in the instrument
panel cluster ever comes on and stays on, it
means that something may be wrong with the
air bag system. If this ever happens, have the
CAUTION: (Continued)
CAUTION: (Continued)
vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger's seat may not have the protection
of the frontal air bag. See ªAir Bag Readiness
Lightº in the Index for more on this, including
important safety information.
Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates.
You may want to consider not using seat covers or other
aftermarket equipment if your vehicle has the passenger
sensing system.
{CAUTION:
Stowing of articles under the passenger's seat
or between the passenger's seat cushion and
seatback may interfere with the proper
operation of the passenger sensing system.

Automatic Transmission Operation
If your vehicle is equipped with an automatic
transmission, it features an electronic shift position
indicator within the instrument panel cluster. This display
must be powered anytime the shift lever is capable of
being moved out of PARK (P). See
Fuses and Circuit
Breakers on page 5-110.
There are several different positions for your shift lever.
PARK (P):This position locks your rear wheels. It's the
best position to use when you start your engine because
your vehicle can't move easily. If your vehicle is equipped
with the Allison
žTransmission, use park for stationary
operation of the Power Takeoff (PTO) (if equipped).
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake ®rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
CAUTION: (Continued)
CAUTION: (Continued)
You or others could be injured. To be sure
your vehicle will not move, even when you are
on fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
See ªShifting Into Park (P)º in the Index. If you
are pulling a trailer, see ªTowing a Trailerº in
the Index.
{CAUTION:
If you have four-wheel drive, your vehicle will be
free to roll Ð even if your shift lever is in PARK
(P) Ð if your transfer case is in NEUTRAL. So,
be sure the transfer case is in a drive gear,
two-wheel high (2H) or four-wheel high (4H) or
four-wheel low (4L) Ð not in NEUTRAL. See
ªShifting into Park (P)º in the index.

Tow/Haul Mode
(Automatic Transmission)
Your vehicle may be equipped with a tow/haul mode.
The selector button is located on the end of the column
shift lever. You can use this feature to assist when
towing or hauling a heavy load. Turn tow/haul on and
off by pressing the button until the tow/haul indicator
light illuminates on the instrument panel. See ªTow/Haul
Mode²under
Towing a Trailer on page 4-68for more
information.
Overdrive Disable
(Allison Transmissionž)
If your vehicle has an Allison Transmissionžyou may
have the overdrive disable feature. The overdrive disable
feature prevents the transmission from shifting into
®fth (5) gear. The selector button is located on the end
of the column shift lever. You can turn overdrive
disable on and off by pressing and holding the button at
the end of the column shift lever until the indicator
light, on the instrument panel, illuminates.

Automatic Transfer Case
The transfer case buttons
are located to the left of
the instrument panel
cluster.
Use these switches to shift into and out of four-wheel
drive.

You can choose among four driving settings:
h(2HI):This setting is used for driving in most street
and highway situations. Your front axle is not engaged
in two- wheel drive. This setting also provides the
best fuel economy.
AUTO 4WD:This setting is ideal for use when road
conditions are variable. When driving your vehicle
in AUTO 4WD, the front axle is engaged, but the
vehicle's power is sent to the rear wheels. When the
vehicle senses a loss of traction, the system will
automatically engage four-wheel drive. Driving in this
mode results in slightly lower fuel economy than 2HI.

Electronic Transfer Case
If your four-wheel-drive
vehicle has the electronic
transfer case, the
transfer case switches are
located to the left of the
instrument panel cluster.Use these switches to shift into and out of four-wheel

G(4HI):This setting engages your front axle to help
drive your vehicle. Use 4HI when you need extra
traction, such as on snowy or icy roads, or in most
off-road situations.
