(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.
NOTE
When the vehicle speed reaches the low limit [approxi- mately 40 km/h (25 mph)] during deceleration, the auto-
matrc speed control will be cancelled.

SERVICE ADJUSTMENT PROCEDU$$jF
AUTO-CRUISE CONTROL SYSTEM INSPECTION
AUTO-CRUISE CONTROL MAIN SWITCH CHECK
(I) Turn the ignition key to ON.
(2) Check to be sure that the indicator light within the switch
illuminates when the main switch is switched ON.
AUTO-CRUISE CONTROL
SETTING CHECK
(1) Switch ON the main 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 (within the combina-
tion meter) illuminates.
NOTE

If the vehicle speed decreases to approximately 20 km/h
(12 mph) below the set speed, because of climbing a hill for
example, the auto-cruise control will be
cancelled.

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 SETl-ING
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.
NOTE
Even 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.

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,
when either of the operations below is performed. @ The brake pedal is depressed.
@ The clutch pedal is depressed.

@ TJhEzift lever is moved to the “N” or “P” range.
@I 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
cancelled
when 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” range.

(3) Turn the control switch to RESUME position and release
(RESUME switch
ON*OFF) 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.
ACCELERATOR CABLES INSPECTION AND
ADJUSTMENT

(I) Turn air conditioning and lights OFF. Inspect and adjust at no load.
(2) Warm engine until stabilized at idle.
(3) Confirm idle speed is at prescribed rpm.
(4) Stop engine (ignition switch OFF).
(5) Confirm there are no sharp bends in accelerator cables.
(6) Check inner cables for correct slack.
(7) If there is too much slack or no slack, adjust play by the following procedures.
0 Remove the actuator’s protector.
0 On models with an SOHC engine, turn the ignition
switch to the ON position (without starting the engine)
and leave in that condition for approximately 15
seconds.

@ Adjust accelerator cable B (throttle valve side); after
loosening the adjustment bolts at the intake manifold
plenum side and freeing the inner cable, use the adjust-
ment bolts to secure the plate so that the free play of
the inner cable becomes the standard value.
Standard value:
l-2 mm (.04-.08 in.)
NOTE
If there is excessive play of the accelerator cable, the
vehicle speed drop (“undershoot”) when climbing a
slope will be large.
If there is no play (excessive tension) of the accelerator
cable, the idling speed will increase.
@Confirm that the throttle lever touches the closed throt-
tle position switch.
@ Adjust accelerator cable A (accelerator pedal side) by loosening the lock nut.

@ After making the adjustment of the cable as described above, check to be sure that the throttle lever at the
engine side is caused to move the distance shown in
the illustration when the actuator link is turned.
@ Install the protector to the actuator.
(8) After adjusting, confirm that throttle valve fully opens and closes by operating pedal.

(1) Remove the link protector. (Refer to
P.13-402.)
(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 startingthe 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.
(5) Adjust with adjusting nut A so when link A hits the stopper, the accelerator cable play (inner cable play) reaches the
standard value.
