impact more evenly over the occ.upant’s upper body, stopping the occupant
more gradually. But air bags would not help you
in many types of collisions,
including rollovers and rear and side impacts, primarily because an
occupant’s motion
is not toward the air bag. Air bags should never be
regarded
as anything more than a supplement to safety belts, and then only
in moderate to severe frontal or near-frontal collisions.
What will you see after an air bag inflates?
After the air bag inflates, it quickly deflates. This occurs so quickly that
some people may not even realize the air bag inflated. Some components of
the air bag module
in the steering wheel hub will be hot for a short time, but
the part of the bag that comes into contact with you will not be hot to the
touch. There will be some smoke
and dust coming from vents in the deflated
air bag. Air bag inflation
will not prevent the driver from seeing or from
being able to steer the vehicle, nor
will it stop people from leaving the
vehicle.
A CAUTION:
When an air bag inflates, there is dust in the air. This dust could
cause breathing problems for people with
a history of asthma or
other breathing trouble. To avoid this, everyone in the vehicle
should get out as soon as it
is safe to do so. If you have breathing
problems but can’t get out of the vehicle after an air bag\
inflates,
then get fresh air
by opening a window or door.

The air bag is designed to inflate only once. After it inflates, you’ll
need some new parts for your air bag system.
If you don’t get them, the
air
bag system won’t be there to help protect you in another crash. A
new system
will include the air bag module and possibly other parts.
The service manual for your vehicle covers the need to replace other
parts.
Your vehicle is equipped with a diagnostic module, which records
information about the air bag system. The module records information
about the readiness of the system, when
the sensors are activated and
driver’s safety belt usage at deployment.
Let only qualified technicians work on your air bag system. Improper
service can mean that your air bag system won’t work properly. See
your dealer for service.

NOTICE:
Driving with the parking brake on can cause your rear brakes to
overheat. You may have to replace them, and you could also
damage other parts of your vehicle. Always check to be sure
your parking brake is fully released before you drive.
If you are towing a trailer and are parking on any hill: See “Towing a
Trailer” in the Index. That section shows what to do first to keep the trailer
from moving.
Propshaft Brake Burnish Procedure
If you have a 3500 HD model, it is recommended that the propshaft mounted
parking brake be burnished
as part of the new vehicle break in. The parking
brake will work best after
it has been burnished following these instructions.
Make
10 (ten) stops, using the parking brake foot pedal, from 20 mph (32
km/h) about
2 1/2 miles (4 km) apart. In between stops, drive the vehicle at
20 mph (32 km/h).
Torque Lock
When parking, the weight of the vehicle may put too much force on the
parking pawl
in the transmission. It may be difficult to pull the selector
lever out of
PARK (P). This is called ”torque lock.” To find out how to
avoid torque lock, see “Torque Lock” later in this section.

Transmission Models Only)
