CRUISE CONTROL SETTING CHECK(1) Switch ON the main switch.
(2) Drive at the desired speed within the range of approximate-
ly 40
- 145 km/h (25 - 90 mph).
(3) Operate the control switch downward. (SET switch: ON)
(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 CRUISE indicator light (within the combination
meter) illuminates.
NOTEIf the vehicle speed decreases to approximately 15 km/h (9
mph) below the set speed, because of climbing a hill for
example, the cruise control will be cancelled.
SPEED-INCREASE SETTING CHECK(1) Set to the desired speed.
(2) Operate the control switch upward. (RESUME switch: ON)
(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) Operate the control switch downward. (SET switch: ON)
(3) Check to be sure that deceleration continues while the
switch is held, and that when it is released the constant
speed at the time when it was released becomes the
driving speed.
NOTEWhen the vehicle speed reaches the low limit [approx-
imately 40 km/h (25 mph)] during deceleration, the cruise
control will be cancelled.
CRUISE CONTROL CANCELLATION AND SET SPEED RE-
SUME CHECK(1) Set cruise control.
(2) In the cruising condition of the cruise control mode, check
that when any of the following operations are performed,
the normal drive mode is restored and
,the vehicle coasts
smoothly.@ Move the control switch toward you. (CANCEL switch:@ Depress the brake pedal.@ Depress the clutch pedal.
@ Place the gear selector lever in the N range.

VEHICLES SPEED SENSOR INSPECTION
Use circuit tester to check circuit repeats off/on between
terminals when speedometer shaft turned several times.

(1) Remove the vehicle’s speed sensor and connect as shown
in the illustration, using a 3
- 10 kQ resistance.
(2) Use a voltmeter to check for voltage at terminals @ and @
when the pulse generator shaft is turning. (One revolution
is four pulses.)

08FOO27. ADJUSTMENT OF CLEARANCE BETWEEN CLUTCH
BOOSTER PUSH ROD AND PISTON
Adjust the clearance (A) between the clutch booster push
rod and piston as follows:
(1) Measure the dimension
(B) between the master cylin-
der end face and piston.
NOTETo obtain
(B), first take measurement with a square
placed on the master cylinder end’ face. Then, subtract
the thickness of the square to arrive at (B).
(2) Obtain the dimension
(C) between the clutch booster
mounting surface on the master cylinder and the end
face.(3) Measure the dimension
(D) between the master cylin-
der mounting surface on. clutch booster and the push
rod end.
NOTETo obtain
(D). first take measurement with a square
placed on the clutch booster. Then, subtract the
thickness of the square to arrive at
(D).
(4) Using the measured values obtained in (1) through (3).obtain the clearance (A) between the clutch booster
push rod and piston.
Standard value: [A (A = B
- C - D )]
0.2j - 0.46 mm (.0082 - .0181 in.)
[Atmospheric pressure][When the clutch booster negative pressure of 66.7
kPa(9.7 psi) is applied, the clearance (A) becomes 0.1 to 0.3
mm
(.0039 to .0118 in.).]
(5) If the clearance is not within the standard value range,
adjust by changing the push rod length by turning the
adjustable end of the push rod.
CautionImproper clearance may cause excessive brake
drag.JTSB Revision
