(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.

COOLING -Service Adjustment Procedures T210863
SERVICE ADJUSTMENT PROCEDUl$t&
ENGINE COOLANT LEAK CHECK
1. Loosen radiator cap.
2. Confirm that the engine coolant level is up to the filler
neck.
3. Install a radiator cap tester to the radiator filler neck and
apply 160
kPa (23 psi) pressure. Hold pressure for. two
minutes, while checking for leakage from the radiator, hose or connections.
Caution
Be sure to completely clean away any moisture from
the places checked. When the tester is removed, be careful not to spill anyengine coolant from it.
Be careful, when installing and removing the tester
and when testing, not to deform the filler neck of the
radiator.
4.If there is leakage, repair or replace the appropriate part.
RADIATOR CAP PRESSURE TEST
MlOFBAA
1.Use a special tool to attach the cap to the tester.
2.Increase the pressure until the indicator of the gage stops
moving.
Limit: 65
kPa (9.2 psi)
Standard value:
75- 105 kPa (1 1 - 15 psi)
3.Replace the radiator cap if the reading does not remain at
or above the limit.
NOTE
Be sure that the cap is clean before testing, since rust or
other foreign material on the cap seal will cause an im-
proper indication.

SELECTOR LEVER OPERATION CHECKM23flAE
1. Shift selector lever to each range and check that lever
moves smoothly and is controled. Check that position
indicator is correct.
2.Check to be sure the selector lever can be shifted to each
position (by button operation as shown in the illustration).
3. Start the engine and check if the vehicle moves forward
when the selector lever is shifted from N to D, and moves
backward when shifted to R.
4. When the shift lever malfunctions, adjust control cable and selector lever sleeve. Check for worn shift lever
assembly sliding parts.
NOTE
To move the selector lever from the “P” position to any
other position, first turn the ignition key to any position
other than “LOCK (OFF)” and depress the brake pedal.

KEY INTERLOCK MECHANISM CHECKM23FUAA
Completely stop the vehicle and switch OFF the engine before
making the check.
1.Check to be sure that, under the following conditions, the
selector lever cannot be moved from the “P” position to
any other position.
Also check, at the same time, that the button cannot be
pressed.
Ignition key position:“LOCK (OFF)“, or removed
Brake pedal: Depressed
2.Check to be sure that, under the following conditions, the selector lever can be moved from the “P” position to any
other position.
Press the button a few times and check to be sure that the
selector lever moves smoothly.
Ignition key position: “ACC”
Brake pedal : Depressed
Button: Pressed
3.Check to be sure that, at all positions of the selector lever
(other than “P”), the ignition key cannot be turned to the
“LOCK (OFF)” position.
Check to be sure that the ignition key smoothly turns to the
“LOCK (OFF)” position when the selector lever is then set
to the “P” position and the button is released.
If a malfunction is discovered when following the above
checking procedures,either adjust or check the key
interlock cable mechanism. (Refer to
P.23-97.)
