key GMC SIERRA 1998 Owners Manual

The best way to protect the fetus is to protect the
mother. When
a safety belt is worn properly, it’s more
likely that the fetus
won’t be hurt in a crash. For
pregnant women,
as for anyone, the key to making
safety belts effective
is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger’s
safety belt properly, see “Driver Position” earlier in
this section.
The right front passenger’s safety belt works the same
way as the driver’s safety belt
-- except for one thing. If
you ever pull the lap portion of the belt out all the way,
you will engage
the child restraint locking feature. If
this happens, just let the belt go back all the way and
start again.
Air Bag System
This part explains the air bag system.
Your vehicle may have a
“Next Generation’‘
reduced-force frontal air
bag for the driver and
another “Next Generation”
reduced-force frontal air
bag for the right front
passenger. If
it does, it will
say AIR BAG
on the middle
part
of the steering wheel.
Reduced-force frontal air
bags are designed to help
reduce the risk of injury from the force of
an inflating
air bag. But even these air bags must inflate very
quickly
if they are to do their job and comply with
federal regulations.

I 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.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect 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
dealer and the service manual have information about
servicing your vehicle and the air
bag system. To
purchase a service manual, see “Service and Owner
Publications”
in the Index.
If your vehicle ever gets into a lot of water -- such as
water up to the carpeting or higher -- or if water enters
your vehicle
and soaks the carpet, the air bag controller
can be soaked and ruined. If this ever happens, and then
you start your vehicle, the damage could make the air
bags inflate, even if there’s no crash.
You would have to
replace the air bags
as well as the sensors and related
parts. If your vehicle is ever
in a flood? or if it‘s exposed
to water that soaks the carpet, you can avoid needless
repair costs
by turning off the vehicle immediately.
Don’t
let anyone start the vehicle, even to tow it, unless
the battery cables are first disconnected.
I
For up to 10 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.
~~
The ail- bag system does not need regular maintenance.

’ A CAUTION:
-
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s air bag inflates, even though your
vehicle has reduced-force frontal
air bags. This is
because the back of the rear-facing child
i restraint would be very close to the inflating air
bag. Be sure to turn off the air bag before using a
rear-facing child restraint in the right front seat
position.
If a forward-facing child restraint is
suitable for your child, always move the
passenger seat as
far back as it will go.
To turn off the right front passenger’s air bag, insert
your ignition key into the switch, push
in, and move the
switch to
AIR BAG OFF.
The AIR BAG OFF light will come on to let you know
that the right front passenger’s air bag is off. The right
front passenger’s air bag
will remain off until you turn it
back on again, and the AIR BAG OFF light will stay on
to remind you that the air bag is off.

To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety belt
will move freely again and be ready to work for an adult
or larger child passenger.
If your vehicle has air bags, turn on the right front
passenger’s air bag when you remove the rear-facing
child restraint.
To turn the air bag on again, insert your ignition key into the
switch, push in, and move the switch to the
ON position.
If the right front passenger’s air bag is turned
off, the person sitting there won’t have the extra
protection of an
air bag. In a crash, the air bag
wouldn’t be able to inflate and help protect the
person sitting there. Make sure the air bag is
turned on unless you are using
a rear-facing child
restraint in the right front seat position.
