Poor Fuel Economy Symptom
StepActionVa l u e ( s )Ye sNo
1DEFINITION:
Fuel economy, as measured by an actual road test, is
noticeably lower than expected. Also, economy is
noticeably lower than it was on this vehicle at one time,
as previously shown by an actual road test. (Larger than
standard tires will cause odometer readings to be
incorrect, and that may cause fuel economy to appear
poor when it is actually normal.)

SUPPLEMENTAL RESTRAINT SYSTEM 9J–12
Deployed Air Bag Assembly (Driver Side)
“You should wear gloves and glasses. After the air bag
assembly has been deployed, the surface of the air bag
may contain solid particulate. This solid particulate
c o n s i s t s p r i m a r i l y o f b y p r oducts of the chemical reaction,
Potassium Chloride and copper metal dust. Compounds
of Potassium Borate, Strontium Chloride, Copper
Chloride, and Ammonium Chloride may be found in
amounts of about 1% (each) of the total particulate.”
Deployed Pretensioner Seat Belt.
You should wear gloves and safety glasses. After the
pretensioner seat belt has been deployed, the surface of
the pretensioner seat belt cylinder may heating up.
Air Bag Assembly and/or Pretensioner
Seat Belt Scrapping Procedure.
During the cause of vehicle’s useful life, certain situations
may arise which will necessitate the disposal of a live air
bag and/or pretensioner seat belt. (This information
covers proper procedures for disposing of a live air bag
assembly and/or pretensioner seat belt.)
Before a live air bag assembly can be dispose off, it must
be deployed.
A live air bag assembly and/or pretensioner seat belt
must not be disposed of though normal refuse channels.
WARNING: FAILURE TO FOLLOW PROPER
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AIR
BAG ASSEMBLY DISPOSAL PROCEDURES CAN
RESULT IN AIR BAG DEPLOYMENT WHICH MAY
CAUSE PERSONAL INJURY. AN UNDPLOYED AIR
BAG ASSEMBLY MUST NOT BE DISPOSED OF
THROUGH NORMAL REFUSE CHANNELS. THE
UNDEPLOYED AIR BAG ASSEMBLY CONTAINS
SUBSTANCES THAT CAN CAUSE SEVERE ILLNESS
OR PERSONAL INJURY IF THE SEALED CONTAINER
IS DAMAGED DURING DISPOSAL. DISPOSAL IN
ANY MANNER INCONSISTENT WITH PROPER
PROCEDURES MAY BE A VIOLATION OF LOCAL
LAW.
In situations which require deployment of a live air bag
assembly, deployment may be accomplished inside or
outside the vehicle. The method employed depends
upon the final disposition of the particular vehicle, as
noted in “Deployment Outside Vehicle” and “Deployment
Inside Vehicle” in this section.
Cautions About Air Bag Deployment And
Disposal
Failure to follow proper procedures could result in
erroneous air bag deployment which may cause personal
injury be sure to follow proper procedures.
1. Turn off (Lock) the ignition switch and disconnect the
minus terminal of the battery, then start the work 15 or
more sec later. (Air bag is designed to work by the
back-up power source even if the battery power
source is cut off at vehicle collision).
2. Be sure not to disassemble the air bag.
3. Do not give an impact to the air bag and bring the air
bag close to magnet. (The air bag could deploy
unexpectedly).4. Place the air bag with its trim cover up.
5. Do not let the air bag deploy directly on the floor. (The
air bag may be blown off 2
3 m (6.5 or 10 feet)).
6. Be sure to install the air bag firmly to a deployment
tool (fixing tool).
7. Set a battery 10 m (33 feet) or more away from the air
bag.
8. Before disconnecting air bag harness, ground the
worker by touching the vehicle outer panel with bare
hand.
9. When connecting or disconnecting the harness, do
not work just in front of the air bag.
10. As deployment gives rise to big sound, warn the
people around against it. Further, try to reduce the
sound by covering the steering wheel or tires, and
shut the vehicle windows in case of deployment
inside the vehicle.
11. As deployment generates smoke, select a well
ventilated place. (In case of deployment indoors,
avoid deployment just under a fire alarm, smoke
sensor, and fluorescent lamps).
12. Be careful not to inhale the smoke after deployment.
13. If part of the vehicle glass is damaged, cover the
vehicle with a car cover to prevent the glass from
braking at the time of deployment.
14. Do not touch the air bag immediately after
deployment, since it remains hot for 30 minutes.
15. Do not water the air bag immediately after
deployment.
16. Wear safety glasses and gloves throughout the work
and wash the glasses and gloves after the work.
17. Do not reuse the removed air bag for another vehicle.
(Deployment characteristic is different with vehicle
types).
Deployment Outside Vehicle (Driver Air
Bag Assembly)
Deployment outside the vehicle is proper when the
vehicle is to be returned to service. This includes, for
example, situations in which the vehicle will be returned to
useful service after a functionally or cosmetically deficient
air bag assembly is replaced. Deployment and disposal
of a malfunctioning air bag assembly is, of course, subject
to any required retention period.
For deployment of a live (undeployed) air bag assembly
outside the vehicle, the deployment procedure must be
followed exactly. Always wear safety glasses during this
deployment procedure until a deployed air bag assembly
is scrapped or until an undeployed air bag assembly is
shipped. Before performing the procedures you should
be familiar with servicing the SRS and with proper
handling of the air bag assembly. Procedures should be
read fully before they are performed.
The following procedure requires use of 5–8840–2468–0
SRS deployment harness with appropriate pigtail
adapter. Do not attempt procedure without
5–8840–2468–0 adapter.
WARNING: FAILURE TO FOLLOW PROCEDURES IN
THE ORDER LISTED MAY RESULT IN PERSONAL
INJURY. NEVER CONNECT DEPLOYMENT

7. How to fix Driver air bag.
1. Fix the air bag with its trim cover up on a tire with a
wheel using an automobile use wire harness,
(core size: 0.05 inch) or a wire trebly at two or
more points.
2. Connect SRS air bag assembly to the double pole
extension cord of the air bag deployment
harness.
Do not connect the deployment harness to a pow-
er source until air bag deployment.
(If connected the SRS air bag assembly deploys
immediately)
NOTE: Ensure that the pigtail adapter is firmly seated into
the air bag assembly connector. Failure to fully seat the
connectors may leave the shorting bar located in the air
bag assembly connector functioning (shorting the
deployment circuit) and may result in non deployment of
the air bag assembly.

3. Place three tires without wheel on the tire on
which air bag is fixed and a tire with a wheel on
top.
Bind the five tires with a rope so that the tires may
not collapse.

WARNING: SAFETY PRECAUTIONS MUST BE
OBSERVED WHEN HANDING A DEPLOYED AIR BAG
ASSEMBLY. AFTER DEPLOYMENT, THE METAL

THE DEPLOYED AIR BAG ASSEMBLY MUST BE
MOVED BEFORE IT IS COOL, WEAR GLOVES AND
HANDLE BY THE AIR BAG IT SELF.
11. Disconnect the pigtail adapter from the air bag
assembly as soon after deployment as possible to
avoid damage to the pigtail adapter or SRS
deployment harness from contacting the hot air bag
assembly canister. The pigtail adapter and SRS
deployment harness are designed to be reused. They
should, however, be inspected for damage after each
deployment and replaced if necessary.
12. Dispose of the deployed air bag assembly through
normal refuse channels after it has cooled for at least
30 minutes.
