AIRBAG REMOVAL PROCEDURES.
TURN SIGNALSÐAC, AY, AA AND AP BODIES
The turn signals are part of the multi-function switch.
Which contains electrical circuitry for turn signal, cor-
nering lamps, hazard warning, headlamp beam select,
headlamp optical horn, windshield wiper, pulse wipe
and windshield washer switching. The integrated switch
assembly is mounted to the left hand side of the steer-
ing column. When the driver wishes to signal his inten-
tions to change direction of travel, he moves the lever
upward to cause the right signals to flash and down-
ward to cause the left signals to flash. After completion
of a turn the system is deactivated automatically. As
the steering wheel returns to the straight ahead posi-
tion, a canceling cam of two lobes molded to the clock-
spring mechanism comes in contact with the cancel
actuator on the turn signal multi-function switch as-
sembly. Either cam lobe, pushing on the cancel actua-
tor, returns the switch to the off position. If only momentary signaling such as indication of a
lane change is desired, the switch is actuated to a left
or right intermediate detent position. In this position
the signal lamps flash as described above, but the
switch returns to the OFF position as soon as the lever
is released.
When the system is activated, 1 of 2 indicator
lamps mounted in the instrument cluster flashes in
unison with the turn signal lamps, indicating to the
driver that the system is operating.
AG AND AJ BODIES
The turn signals are actuated with lever on the left
side of the instrument panel switch pod. When the
driver wishes to signal his intentions to change di- rection of travel, he moves the lever upward to cause
the right signals to flash and downward to cause the
left signals to flash. After completion of a turn the system is deacti-
vated automatically. The cancellation switch in the
steering column sends a signal to a remote turn sig-
nal switch in the switch pod to cancel the turn signal
function. As the steering wheel returns to the
straight ahead position from a turn, a cancel cam
which is located on the steering wheel contacts a
cancel flipper located on the cancellation switch.
When the flipper is contacted by the cancel cam in
the proper rotational direction, the cancel switch
sends a signal to the remote turn signal switch. If only momentary signaling such as indication of a
lane change is desired, the switch is actuated to a
left or right intermediate detent position. In this po-
sition the signal lamps flash as described above, but
the switch returns to the OFF position as soon as the
lever is released. When the system is activated, 1 of 2 indicator
lamps mounted in the instrument cluster flashes in
unison with the turn signal lamps, indicating to the
driver that the system is operating.
HAZARD WARNING SYSTEM
The hazard warning system is actuated by a push
button located on the top of the steering column be-
tween the steering wheel and the instrument panel.
The hazard switch is identified with a double trian-
gle on top of the button. Push and release the button
to turn the hazard function ON or OFF. The button
will move out from the steering column in the ON
position and will remain in toward the column in the
OFF position.
CHIME FUNCTIONÐAC, AG, AJ AND AY
The chime will sound after the vehicle has traveled
a distance of 0.6 miles at a speed above 15 miles per
hour.
