SERVICE ADJUSTMENT PROCEDM%,&ACCELERATOR CABLE
CNSPECTION AN&I ”ADJUSTMENT
For models equipped with the auto-cruise control systemreferto
P.14-136.(1) Turn air conditioner 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 cable.
6) Check inner cable for correct slack.
7) If there is too much slack or no slack, adjust play by the
following procedures.
@ 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.@
Loosen the adjusting bolts on the air intake plenum, andthen secure the outer cable so that the free play of the
inner cable will be the standard value.
Standard value:
jlr
l-2 mm (.04-.08 in.) \. *
3-5 mm (.12-.20 in.)
NOTEIf 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.
(8) After adjusting, confirm that throttle valve fully opens and
closes by operating pedal.
(9) Adjust accelerator cable play and confirm throttle lever
stopper touches the idle switch.
ACCELERATOR SWITCH INSPECTION AND
ADJUSTMENT
NlWlEB(1) After warming up the engine, check to be sure that the
accelerator switch is ON when the accelerator pedal’ is in
the free condition. If there is a malfunction, adjust by using
the adjusting bolt.
(2) Press the accelerator pedal by hand until the accelerator
switch switches from ON to OFF and confirm that the
amount of pedal movement (A in the figure) is within the
standard value range.
Standard value:
Accelerator switch switching point
2-6 mm
(.08-.24 ‘in.)
(3) If the distance (A in the figure) is not within the standard
value, adjust it by using the adjusting bolt.

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.
