GENERAL DESCRIPTION
There are six battery fluid caps at the top of the
battery. These are covered by a paper label.
The battery is completely sealed except for the six
small vent holes at the side. These vent holes per-
mit the escape of small amounts of gas generated
by the battery.
This type of battery has the following advantages
over conventional batteries:1. There is no need to add water during the entire
service life of the battery.
2. The battery protects itself against overcharging.
The battery will refuse to accept an excessive
charge.
(A conventional battery will accept an excessive
charge, resulting in gassing and loss of battery
fluid.)
3. The battery is much less vulnerable to self-
discharge than a conventional type battery.
DIAGNOSIS
1. VISUAL INSPECTION
Inspect the battery for obvious physical damage,
such as a cracked or broken case, which would
permit electrolyte loss.
Replace the battery if obvious physical damage is
discovered during inspection.
Check for any other physical damage and correct it
as necessary. If not, proceed to Step 2.
2. HYDROMETER CHECK
There is a built-in hydrometer (Charge test indica-
tor) at the top of the battery. It is designed to be
used during diagnostic procedures.Before trying to read the hydrometer, carefully
clean the upper battery surface.
If your work area is poorly lit, additional light may
be necessary to read the hydrometer.

BATTERY CHARGING
Observe the following safety precautions when
charging the battery:
1. Never attempt to charge the battery when the
fluid level is below the lower level line on the
side of the battery. In this case, the battery
must be replaced.
2. Pay close attention to the battery during the
charging procedure.
Battery charging should be discontinued or the
rate of charge reduced if the battery feels hot to
the touch.
Battery charging should be discontinued or the
rate of charge reduced if the battery begins to
gas or spew electrolyte from the vent holes.
3. In order to more easily view the hydrometer
blue dot or ring, it may be necessary to jiggle or
tilt the battery.
4. Battery temperature can have a great effect on
battery charging capacity.
5. The sealed battery used on this vehicle may be
either quick-charged or slow-charged in the
same manner as other batteries.
Whichever method you decide to use, be sure
that you completely charge the battery. Never
partially charge the battery.
JUMP STARTING
JUMP STARTING WITH AN AUXILIARY
(BOOSTER) BATTERY
CAUTION:
Never push or tow the vehicle in an attempt to
start it. Serious damage to the emission system
as well as other vehicle parts will result.
Treat both the discharged battery and the
booster battery with great care when using
jumper cables. Carefully follow the jump
starting procedure, being careful at all times to
avoid sparking.
WARNING:
Failure to carefully follow the jump starting
procedure could result in the following:
1. Serious personal injury, particulaly to
your eyes.
2. Property damage from a battery explo-
sion, battery acid, or an electrical fire.
3. Damage to the electronic components of
one or both vehicles particularly. Never expose the battery to an open flame or elec-
trical spark. Gas generated by the battery may catch
fire or explode.
Remove any rings, watches, or other jewelry before
working around the battery. Protect your eyes by
wearing an approved set of goggles.
Never allow battery fluid to come in contact with
your eyes or skin.
Never allow battery fluid to come in contact with
fabrics or painted surfaces.
Battery fluid is a highly corrosive acid.
Should battery fluid come in contact with your
eyes, skin, fabric, or a painted surface, immediately
and thoroughly rinse the affected area with clean
tap water.
Never allow metal tools or jumper cables to come
in contact with the positive battery terminal, or any
other metal surface of the vehicle. This will protect
against a short circuit.
Always keep batteries out of the reach of young
children.
JUMP STARTING PROCEDURE
1. Set the vehicle parking brake.
If the vehicle is equipped with an automatic
transmission, place the selector lever in the
ÒPARKÓ position.
If the vehicle is equipped with a manual trans-
mission place the shift lever in the ÒNEUTRALÓ
position.
Turn ÒOFFÓ the ignition.
Turn ÒOFFÓ all lights and any other accessory
requiring electrical power.
2. Look at the built-in hydrometer.
If the indication area of the built-in hydrometer
is completely clear, do not try to jump start.
3. Attach the end of one jumper cable to the posi-
tive terminal of the booster battery.
Attach the other end of the same cable to the
positive terminal of the discharged battery.
Do not allow the vehicles to touch each other.
This will cause a ground connection, effectively
neutralizing the charging procedure.
Be sure that the booster battery has a 12 volt
rating.
4. Attach one end of the remaining cable to the
negative terminal of the booster battery.
Attach the other end of the same cable to a
solid engine ground (such as the A/C com-
pressor bracket or the generator mounting
bracket) of the vehicle with the discharged bat-
tery.
This ground connection must be at least 450
mm (18 in) from the battery of the vehicle
whose battery is being charged.

SUPPLEMENTAL RESTRAINT SYSTEM 9J±14
10. Place a power source near the shorted end of the
SRS deployment harness. Recommended
application: 12 volts minimum, 2 amps minimum. A
vehicle battery is suggested.
11. Connect the driver air bag assembly to the pigtail
adapter on the SRS deployment harness.
Deployment harness shall remain shorted and not be
connected to a power source until the air bag is to be
deployed. The driver air bag assembly will
immediately deploy the air bag when a power source
is connected to it.
NOTE: Ensure that the pigtail adapter is firmly seated into
the driver air bag assembly connector. Failure to fully
seat the connectors may leave the shorting bar located in
the driver air bag assembly connector functioning
(shorted) and may result in nondeployment of the driver
air bag assembly.
12. Verify that the area around the driver air bag
assembly is clear of all people and loose or flammable
objects.
13. Verify that the driver air bag assembly is resting with
its trim cover facing up.
14. Notify all people in the immediate area that you intend
to deploy the driver air bag. The deployment will be
accompanied by a substantial noise which may
startle the uninformed.
15. Separate the two banana plugs on the SRS
deployment harness.
NOTE: When the air bag deploys, the driver air bag
assembly may jump about 3 m (ten feet) vertically. This
is a normal reaction of the driver air bag to the force of the
rapid gas expansion inside the air bag.
NOTE: W h e n t h e a i r b a g deploys, the rapid gas
expansion will create a substantial noise. Notify all
people in the immediate area that you intend to deploy the
driver air bag.
WARNING: D E P L O Y M E N T HARNESS SHALL
REMAIN SHORTED AND NOT BE CONNECTED TO A
POWER SOURCE UNTIL THE AIR BAG IS TO BE
DEPLOYED. THE AIR BAG ASSEMBLY WILL
IMMEDIATELY DEPLOY THE AIR BAG WHEN A
POWER SOURCE IS CONNECTED TO IT.
CONNECTING THE DEPLOYMENT HARNESS TO
THE POWER SOURCE SHOULD ALWAYS BE THE
LAST STEP IN THE AIR BAG ASSEMBLY
DEPLOYMENT PROCEDURE. FAILURE TO FOLLOW
PROCEDURES IN THE ORDER LISTED MAY RESULT
IN PERSONAL INJURY.
16. Connect the SRS deployment harness wires to the
power source to immediately deploy the driver air
bag. Recommended application: 12 volts minimum, 2
amps minimum. A vehicle battery is suggested.
17. Disconnect the SRS deployment harness from the
power source.
18. Short the two SRS deployment harness leads
together by fully seating one banana plug into the
other.19. In the unlikely event that the driver air bag assembly
did not deploy after following these procedures,
proceed immediately with Steps 24 through 26. If the
driver air bag assembly did deploy, proceed with
Steps 20 through 23.
20. Put on a pair of shop gloves and safety glasses to
protect your hands and eyes from possible irritation
and heat when handling the deployed driver air bag
assembly. After the air bag assembly has been
deployed, the surface of the air bag may contain a
powdery residue. This solid particulate consists
primarily of by products 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.
WARNING: S A F E T Y P R ECAUTIONS MUST BE
OBSERVED WHEN HANDING A DEPLOYED AIR BAG
ASSEMBLY. AFTER DEPLOYMENT, THE METAL
SURFACES OF THE AIR BAG ASSEMBLY WILL BE
VERY HOT. ALLOW THE INFLATOR MODULE TO
COOL BEFORE HANDLING ANY METAL PORTION
OF IT. DO NOT PLACE THE DEPLOYED AIR BAG
ASSEMBLY NEAR ANY FLAMMABLE OBJECTS.
FAILURE TO FOLLOW PROCEDURES MAY RESULT
IN FIRE OR PERSONAL INJURY.
AFTER A DRIVER AIR BAG ASSEMBLY HAS BEEN
DEPLOYED, THE METAL CANISTER AND
SURROUNDING AREAS OF THE DRIVER AIR BAG
ASSEMBLY WILL BE VERY HOT. DO NOT TOUCH
THE METAL AREAS OF THE DRIVER AIR BAG
ASSEMBLY FOR ABOUT TEN MINUTES AFTER
DEPLOYMENT. IF THE DEPLOYED DRIVER AIR BAG
ASSEMBLY MUST BE MOVED BEFORE IT IS COOL,
WEAR GLOVES AND HANDLE BY THE AIR BAG OR
TRIM COVER.
21. Disconnect the pigtail adapter from the driver air bag
assembly as soon after deployment as possible. This
will prevent damage to the pigtail adapter or SRS
deployment harness due to possible contact with the
hot driver air bag assembly canister. The pigtail
adapter can be reused. They should, however, be
inspected for damage after each deployment and
replaced if necessary.
22. Dispose of the deployed driver air bag assembly
through normal refuse channels after it has cooled for
at least 30 minutes.
23. Wash your hands with mild soap and water afterward.
NOTE: The remaining steps are to be followed in the
unlikely event that the driver air bag assembly did not
deploy after following these procedures.
24. Ensure that the SRS deployment harness has been
disconnected from the power source and that its two
banana plugs have been shorted together by fully
seating one banana plug into the other.
25. Disconnect the pigtail adapter from the driver air bag
assembly.
