MULTI-FUNCTION SWITCH (Continued)
HAZARD WARNING SYSTEM
The hazard warning system is actuated by a push
button located in the multi-function switch (Fig. 26)
on the top of the steering column between the steer-
ing wheel and the instrument panel. The hazard
switch is identified with a double triangle on front of
the button.
The hazard warning system allows the vehicle
operator to provide the drivers of other vehicles in
near proximity an optical indication that the vehicle
is disabled or is an obstacle to traffic flow. Unlike the
turn signal system, the hazard warning system has
battery current at all times, regardless of ignition
switch position.

OPERATION

MULTI-FUNCTION SWITCH
When the driver wishes to signal his intentions to
change direction 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 deactivated automatically. As the
steering wheel returns to the straight ahead position,
a canceling cam molded to the clockspring mecha-
nism comes in contact with the cancel actuator on
the turn signal multi-function switch assembly. The
cam lobe, pushing on the cancel actuator, 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, one of two 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
When the hazard warning system is activated, the
combination flasher will cause both the right and left
side turn signal indicator lamps, front park/turn sig-
nal lamps, front side marker lamps and rear turn
signal lamps to flash on and off. If the exterior lamps
are turned off, the front park/turn signal lamps and
the front side marker lamps will flash in unison. If
the exterior lamps are turned on, the front park/turn
signal lamps and the side marker lamps will flash
alternately.
