refrigerant container.


1) Make sure the evacuation process is correctly completed.
2) Connect the center-hose of the manifold gauge to the
refrigerant container.






Turn the charge valve handle counterclockwise to purge
to the charging line and purge any air exiting in the
center-hose of the manifold gauge.
3) Open the low-pressure hand valve and charge the
refrigerant about 200 g (0.44 lbs.).






Make sure the high-pressure hand valve is closed.






Avoid charging the refrigerant by turning the refrigerant
container upside down.
4) Close the low-pressure hand valve of the manifold gauge.






Check to ensure that the degree of pressure does not
change.
5) Check the refrigerant leaks by using a HFC-134a leak
detector.






If a leak occurs, repair the leak connection, and start all
over again from the first step of evacuation.
6) If no leaks are found, open the low-pressure hand valve of
the manifold gauge. Then continue charging refrigerant to
the system.






When charging the system becomes difficult:
(1) Run the engine at Idling and close the all vehicle
doors.
(2) A/C switch is "ON".
(3) Set the fan control knob (fan switch) to its highest
position.
(4) Set air soure selector lever to “RECIRC”



WARNING
BE ABSOLUTELY SURE NOT TO OPEN THE HIGH-
PRESSURE HAND VALVE. SHOULD THE HIGH-
PRESSURE HAND VALVE BE OPENED, THE HIGH-
PRESSURE REFRIGERANT GAS WOULD FLOW
BACKWARD, AND THIS MAY CAUSE THE REFRIGERANT
CONTAINER TO BURST.
7) When the refrigerant container is emptied, use the following
procedure to replace it with a new refrigerant container.
(1) Close the low-pressure hand valve.
(2) Raise the needle upward and remove the charge valve.
(3) Reinstall the charge valve to the new refrigerant
container.
(4) Purge any air existing in the center hose of the manifold
gauge.
8) Charge the system to the specified amount and then close
the low-pressure hand valve.

9. Turn the SRS coil counter clockwise to full, return
about 3 turns and align the neutral mark. (with SRS
air bag)
CAUTION: When turning the SRS coil counte
r
clockwise to full, stop turning if resistance is felt.
Forced further turning may damage to the cable in
the SRS coil.

10. When installing the steering column cover, be sure to
route each wire harness as illustrated so that the
harnesses do not catch any moving parts.

11. Install steering wheel and align the setting marks
made when removing.
Refer to the adjustment method in case a mark is
not attached in this section.
NOTE: Confirm SRS and Horn harness connector is
fixed by the steering wheel.

CAUTION: Never apply force to the steering wheel in
direction of the shaft by using a hammer or othe
r
impact tools in an attempt to remove the steering
wheel. The steering shaft is designed as an energy
absorbing unit.
12. Tighten the steering wheel fixing nut to the specified
torque.
Torque: 31 - 39 N

13. Support the module and carefully connect the
module connector and horn lead, then install inflato
r
module.
NOTE: Pass the lead wire through the tabs on the
plastic cover (wire protector) of inflator to prevent lead
wire from being pinched.
14. Tighten bolts to specified torque.

15. Install driver knee bolster (reinforcement).
16. Install instrument panel lower cover.
17. Install the engine hood opening lever.
18. Connect the yellow 2-way SRS connector and horn
lead located under the steering column.
19. Connect the battery "-" terminal cable. (with SRS ai
