7. AUTO CANCEL FUNCTION
A) IF ANY OF THE FOLLOWING OPERATING CONDITIONS OCCUR DURING CRUISE CONTROL OPERATION, THE SET
SPEED IS ERASED, CURRENT FLOW TO MAGNETIC CLUTCH IS STOPPED AND THE CRUISE CONTROL IS
RELEASED. (MAIN SW TURNS OFF).
WHEN THIS OCCURS, THE IGNITION SW MUST BE TURNED OFF ONCE BEFORE THE MAIN SW WILL TURN ON.
*OVER CURRENT TO TRANSISTOR DRIVING MOTOR AND/OR MAGNETIC CLUTCH.
*WHEN CURRENT CONTINUED TO FLOW TO THE MOTOR INSIDE THE ACTUATOR IN THE THROTTLE VALVE
OPENº DIRECTION.
*OPEN CIRCUIT IN MAGNETIC CLUTCH.
*MOMENTARY INTERRUPTION OF VEHICLE SPEED SIGNAL.
*SHORT CIRCUIT IN CRUISE CONTROL SW.
*MOTOR DOES NOT OPERATE DESPITE THE MOTOR DRIVE SIGNAL BEING OUTPUT.
B) IF ANY OF THE FOLLOWING CONDITIONS OCCUR DURING CRUISE CONTROL OPERATION, THE SET SPEED IS
ERASED AND THE CRUISE CONTROL IS RELEASED. (THE POWER OF MAGNETIC CLUTCH IS CUT OFF UNTIL
THE SET SW IS ONº AGAIN.)
*WHEN THE VEHICLE SPEED FALLS BELOW THE MINIMUM SPEED LIMIT, APPROX. 40 KM/H (25 MPH)
*WHEN THE VEHICLE SPEED FALLS MORE THAN 16 KM/H (10 MPH) BELOW THE SET SPEED, E.G. ON AN
UPWARD SLOPE.
*WHEN POWER TO THE CRUISE CONTROL SYSTEM IS MOMENTARILY CUT OFF.
8. AUTOMATIC TRANSMISSION CONTROL FUNCTION
*IN OVERDRIVE. IF THE VEHICLE SPEED BECOMES LOWER THAN THE OVERDRIVE CUT SPEED (SET SPEED
MINUS APPROX. 4 KM/H, 2.5 MPH) DURING CRUISE CONTROL OPERATION, SUCH AS DRIVING UP A HILL, THE
OVERDRIVE IS RELEASED AND THE POWER INCREASED TO PREVENT A REDUCTION IN VEHICLE SPEED.
*AFTER RELEASING THE OVERDRIVE, VEHICLE SPEED BECOMES HIGHER THAN THE OVERDRIVE RETURN
SPEED (SET SPEED MINUS APPROX, 2 KM/H, 1.2 MPH) AND THE ECU JUDGES BY THE SIGNALS FROM
POTENTIOMETER OF THE ACTUATOR THAT THE UPWARD SLOPE HAS FINISHED, OVERDRIVE IS RESUMED
AFTER APPROXIMATELY 2 SECONDS.
*DURING CRUISE CONTROL DRIVING, THE CRUISE CONTROL OPERATION SIGNAL IS OUTPUT FROM THE
CRUISE CONTROL ECU TO THE ENGINE CONTROL MODULE. UPON RECEIVING THIS SIGNAL, THE ENGINE
CONTROL MODULE CHANGES THE SHIFT PATTERN TO NORMAL. TO MAINTAIN SMOOTH CRUISE CONTROL
OPERATION (ON A DOWNWARD SLOPE ETC.), LOCK-UP RELEASE OF THE TRANSMISSION WHEN THE IDLING
POINT OF THE THROTTLE POSITION IS ONº IS FORBIDDEN.

GENERAL MAINTENANCE
1. GENERAL NOTES

Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.

Every service item in the periodic maintenance schedule must be performed.

Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).

Maintenance service after the last period should be performed at the same interval as before unless
otherwise noted.

Failure to do even one item an cause the engine to run poorly and increase exhaust emissions.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
Check that the coolant level is between the ºFULLº and ºLOWº lines on the see-through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL
Check that the electrolyte level of all battery cells is between the upper and lower level lines on the case.
6. BRAKE AND CLUTCH FLUID LEVELS
Check that the brake and clutch fluid levels are near the upper level line on the see-through reservoirs.
7. ENGINE DRIVE BELT
Check drive belt for fraying, cracks, wear or oil contamination.
8. ENGINE OIL LEVEL
Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL

Check the level on the dipstick.

The level should be in the ºHOTº or ºCOLDº range depending on the fluid temperature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking brake applied, shift the selector into all positions from ºPº to ºLº,
and then shift into ºPº position.
(c) Pull out the dipstick and wipe off the fluid with a clean rag. Re-insert the dipstick and check that the
fluid level is in the HOT range.
(d) Do this check with the fluid at normal driving temperature (70 - 80°C, 158 - 176°F).
HINT:
Wait until the engine cools down (approx. 30 min.) before checking the fluid level after extended driving at
high speeds, in hot weather, in heavy traffic or pulling a trailer.
11. EXHAUST SYSTEM
If any change in the sound of the exhaust or smell of the exhaust fumes is noticed, have the cause located
and corrected.

13. ACCELERATOR PEDAL
Check the pedal for smooth operation and uneven pedal effort or catching.
14. CLUTCH PEDAL (See page CL-3)
(a) Check the pedal for smooth operation.
(b) Check that the pedal has the proper freeplay.
15. BRAKE PEDAL (See page BR-7 )
(a) Check the pedal for smooth operation.
(b) Check that the pedal has the proper reserve distance and freeplay.
(c) Check the brake booster function.
16. BRAKES
At a safe place, check that the brakes do not pull to one side when applied.
17. PARKING BRAKE (See page BR-9)
(a) Check that the lever has the proper travel.
(b) On a safe incline, check that the vehicle is held securely with only the parking brake applied.
18. AUTOMATIC TRANSMISSION ºPARKº MECHANISM
(a) Check the lock release button of the selector lever for proper and smooth operation.
(b) On a safe incline, check that the vehicle is held securely with the selector lever in ºPº position and all
brakes released.

INSPECTION
1. INSPECT STEERING LINKAGE
(a) Check the steering wheel freeplay.
(See page SR-8)
(b) Check the steering linkage for looseness or damage.
Check that:

Tie rod ends do not have excessive play.

Dust seals and boots are not damaged.

Boot clamps are not loose.
2. INSPECT SRS AIRBAG (Seep page RS-9)
3. INSPECT STEERING GEAR HOUSING OIL
Check the steering gear housing for oil leakage.
4. INSPECT BALL JOINT DUST COVERS
Visually check the dust covers for damage.
5. INSPECT TRANSMISSION OIL (FLUID) AND
DIFFERENTIAL OIL
Visually check the transmission and differential for oil (fluid)
leakage.
If leakage is found, check for the cause and repair it.
6. REPLACE MANUAL TRANSMISSION OIL
(W58: See page MT-4)
(V160: See page MT-3)
7. REPLACE AUTOMATIC TRANSMISSION FLUID
(2JZ-GE: See page AT-2)
