1995 GMC SIERRA key battery

NOTICE:
If you damage the cover for the driver’s air bag, it may not work\

properly. You may have to replace the air bag module.
Do not
open or break the air bag cover.
Servicing Your Air Bag-Equipped Vehicle
The air bag affects how your vehicle should be serviced. There are parts of
the air bag system in several places around your vehicle. You don’t want the
system to inflate while someone is working on your vehicle. Your
GM
dealer and the 1995 GM Service Manual have information about servicing
your vehicle and the air bag system. To purchase
a service manual, see
”Service Publications”
in the Index. The air bag system does not need
regular maintenance.
A CAUTION:
For up to 2 minutes after the ignition key is turned off and the
battery is disconnected, an air bag can still inflate during
improper service.
You can be injured if you are close to an air
bag when it inflates.
Avoid wires wrapped with yellow tape, or
yellow connectors. They are probably part of the air bag system.
Be sure to follow proper service procedures, and make sure the
person performing work for you
is qualified to do so.
Adding Equipment to Your Air Bag-Equipped Vehicle
Q: If I add a push bumper or a bicycle rack to the front of my vehicle,
will it keep the air bag from working properly?
A: As long as the push bumper or bicycle rack is attached to your vehicle
so that the vehicle‘s basic structure isn’t changed. it‘s not likely to keep
the air bags from working properly
in a crash.
Q: What if I add a wow plow? Will it keep the air bag from working
properly?
A: We’ve designed our air bag systems to work properly under a wide
range
of conditions. including snow plowing with vehicles equipped
with the optional Snow Plow Prep Package
(RPO VYU). But don’t
change or defeat the snow plow’s “tripping mechanism.”
If you do, it
can damage your snow plow and your vehicle, and it may cause an air
bag inflation.

Automatic Transmission
There are several different positions for your shift lever.
If your vehicle is equipped with an automatic transmission, it now features
an electronic shift position indicator
within the instrument cluster. This
display must be powered anytime the shift lever is capable
of being moved
out of the
PARK (P) position. This means that if your key is in the OFF
position, but not locked, there will be a small current drain on your battery
which could discharge your battery over
a period of time. If you have a need
to leave your key
in the ignition in the OFF position for an extended period
for any reason,
it is recommended that you disconnect the battery cable
from the battery to prevent discharging your battery.
PARK (P) -This locks your rear wheels. It’s the best position to use
when you start your engine because your vehicle can’t move easily.
