AUTO-CRUISE CONTROL SYSTEM INSPECTION
AUTO-CRUISE CONTROL SWITCH CHECK(1) Turn the ignition key to ON.
(2) Check to be sure that the indicator light within the switch
illuminates when the cruise control switch is switched ON.
(Turn the cruise control switch to the “CRUISE” position.)
AUTO-CRUISE CONTROL SETTING CHECK(1) Switch ON the cruise control switch.
(2) Drive at the desired speed within the range of approxi-
mately 40-145 km/h (25-90 mph).
(3) Press the SET button.
(4) Check to be sure that the speed is the desired constant
speed when the switch is released, and also check to be
sure that the auto cruise indicator light (tithin the combina-tion meter) illuminates.
NOTE1(
If the vehicle speed decreases to approximately 15 km/h
(9 mph) below the set speed, because of climbing a hill for
example, the auto-cruise control will be
cancelled.
SPEED-INCREASE SETTING CHECK
(‘1) Set to the desird speed.
(2) Turn the control switch to RESUME position.
(3) Check to be sure that acceleration continues while the
switch is hold, and that when it is released the constant
speed at the time when it was released becomes the
driving speed.
NOTEEven if, during acceleration, the vehicle speed reaches or
exceeds the high limit [approximately 145 km/h (90
mph)], acceleration will continue, however, when the
switch is released, the set speed (“memorized speed”) will
become the high limit of the vehicle speed.
’ ” ,
SPEED REDUCTION SETTING CHECK(1) Set to the desired speed.
(2) Press the SET button.
(3) Check to be sure that deceleration continues while the
switch is pressed, and that when it is released the
constant speed at the time when it was released becomes
the driving speed.
NOTEIWhen the vehicle speed reaches the low limit [approxi-
mately 40 km/h (25 mph)] during deceleration, the auto-
matic speed control will be
cancelled.

AUTO-CRUISE CONTROL CANCELLATION CHECK(1) Set the auto-cruise control.
”(2) Check to be sure that there is a return to ordinary driving,
and that the illumination of the auto-cruise indicator stops,
‘cwhen either of the operations below is performed.
@ The brake pedal is depressed.
@ The clutch pedal is depressed.
@ The shift lever is moved to the “N” or “P” range.

@ The auto-cruise control main switch is switched OFF.
@ The ignition switch is turned to OFF.
CHECK OF RETURN TO THE SET SPEED BEFORE
CANCELLATION(1) Set the auto-cruise control.
(2) Check to be sure that the auto-cruise control is
cancelledwhen either of the operations below is performed.
@ The brake pedal is depressed.
@ The clutch pedal is depressed.
@I The shift lever is moved to the “N” range. (3) Turn the control switch to RESUME position and release
(RESUME switch
ONdOFF) while driving at a vehicle
speed of approximately 40 km/h (25 mph) or higher.
(4) After switching RESUME switch to OFF, check to be sure
that there is a return to the auto-cruise control speed before
it will be
cancelled and the vehicle will travel at the constant
speed.
A
ACCELERATOR CABLE, THROTTLE CABLE AND
AUTO-CRUISE CONTROL CABLE INSPECTION
AND ADJUSTMENT(1) Remove the link protector. (Refer to P.14140.)
(2) Check that there are no sharp bends and breaks in the
accelerator cable, throttle cable and auto-cruise control
cable.(3) Turn the ignition switch to the ON position (without starting
the engine) and leave in that condition for approximately 15
seconds.(4) Leave plenty of play in each cable and temporarily install
adjusting nuts A,
B, C and adjusting bolts D.

4.Disconnect the high-tension cable, and then while operating
the starting motor intermittently, turn the steering wheel all;
the way to the left and right several times to drain all of the
fluid.
Caution, 35
Be careful not to position thq high-tension able ye&r the
carburetor or the delivery pipe.5. Connect the return hoses securely, and then
secur& it ,with
the clip.6. Fill the oil reservoir with the specified fluid up
td the Ibwerposition of the filter, and then bleed the air.

Specified fluid:MOPAR ATF PLUS (Automatic Transmis-sion Fluid Type 7176)/Automatic trans-
mission fluid “DEXRON” or “DEXRON II”Fluid level change:

BLEEDINGNlSFKAG
1.Jack up the front wheels and support them by using a floor
stand.2. Manually turn the oil pump pulley a few times.
3. Turn the steering wheel all the way to the left and right
several times.
4.Disconnect the high-tension cable, and then, while operatingthe starting motor intermittently, turn the steering wheel all
the way to the left and right several times
(for 1-5 to 20
seconds).
Caution
1. During air bleeding, replenish the fluid supply so thatthe level never falls below the lower positiin
@f the
eiter.I .“:
2. If air bleeding is done while engine is runnind, ‘the air
will be
brokeir up and absorbed intti the fluid;‘?ti’ sureto do the bleeding only while cranking.
5.Connect the ignition cable, and then start the engine (idling).6. Turn the steering wheel to the left and right until there are
no air bubbles in the oil reservoir.
7. Confirm that the fluid is not milky, and that the level is
upito the specified position on the level gauge.
8.Confirm that there is very little change in the fluid level whenthe steering wheel is turned left and right.
9.Check whether or not the change in the fluid level is within5 mm
(.2 in.) when the engine is stopped and when it is
running.
Caution
1.If the change of the fluid level is 5 mm I.2 in.) or more,
the air has not been completely bled from the system,
and thus must be bled completely.2. If the fluid level rises suddenly after the engine is
stopped, the air has not been completely bled.
3. If air bleeding is not complete, there will be abnormal
noises from the pump and the flow-control valve, and
this
condition could cause a lessening of the life of the
pump, etc.
