8B-2 CRUISE CONTROL SYSTEM
General Description
The cruise control keeps the vehicle running at a fixed speed until a signal canceling this fixed speed is received.
W hen the main switch “AUTO CRUISE” is turned on with the vehicle in the running mode, the battery voltage is
applied to the control unit (Engine control module). W hen a signal from the control unit while the vehicle is in this
state, the cruise control actuator is activated to operate the system. Also, while the system is operating, the cruise
control set indicator light in the meter assembly lights up.




RTU7Z0SH019601

1. SET/COAST Switch Function
1. Set Function: W hen the SET/COAST switch is pressed and released with the main switch on, the speed at
which the vehicle is running at that moment is stored in the memory, and the vehicle automatically runs at the
stored speed.
2. COAST-down Function: W hen the SET/COAST switch is kept on while the vehicle in running, the vehicle
decelerates during that time. The speed at which vehicle is running when the control switch is pressed in the
memory, and the vehicle automatically returns to the stored speed.
3. Tap-down Function: W hen the SET/COAST switch is pressed and released instantaneously while the
vehicle is running, the vehicle decelerates a mile for each on/off operation. The vehicle speed at which the
vehicle was running when the SET/COAST was released last is stored in the memory, and the vehicle
automatically returns to this stored speed.

2. RESUME/ACCEL Switch Function
1. Resume Function: W hen the RESUME/ACCEL switch is turned on/off after the system is temporarily
deactivated by pressing the brake or clutch pedal while the vehicle is running, the vehicle resumes the speed
stored before the system was released, and the vehicle automatically runs at the stored speed.
2. Accelerate Function: W hen the RESUME/ACCEL switch is kept on the vehicle accelerates its speed during
that time. The vehicle speed at which the vehicle was running when the switch was turned off is stored in the
memory, and the vehicle automatically returns to this speed.
3. Tap-up Function: W hen the RESUME/ACCEL switch is turned on and off instantaneously while the vehicle
is running, the vehicle decelerates a mile for each on/off operation. The vehicle speed at which the vehicle
was running when the switch was turned off last is stored in the memory, and the vehicle automatically
returns to this stored speed.

CRUISE CONTROL SYSTEM 8B-3
3. CANCEL Function
1. Temporary Cancellation:
• Brake pedal is pressed.
• Clutch pedal is pressed. (M/T)
• Select lever is shifted to any position other than “D”, “3”, “2” or “L”. (A/T)
• Cancel switch is operated.
• Vehicle speed exceeds about 20 km/h over the vehicle speed stored in the memory.
Turning the RESUME/ACCEL switch will return the vehicle to the speed stored in the cruise control memory.
2. Complete Cancellation:
• Starter switch or the main switch is turned off.
• Fail-safe function is activated.
• Vehicle speed is about 38 km/h.
• Speed becomes 20 km/h or less form the speed memorized by control unit.

Removal
1. Disconnect the battery ground cable.
2. Remove the brake switch.
• Disconnect the connector
1.
• Loosen lock nuts of the switch
2.
• Remove the switch by turning it
3 .


Installation
To install, follow the removal procedure in reverse order, noting
the following points.
1. Check to see if the brake pedal has been returned by the
return spring to the specified position.
2. Turn the switch clock-wise until the tip of the threaded
portion of the brake switch contacts the pedal arm.

3. Turn the switch counter-clock-wise until the space between
the tip of the threaded portion and the pedal arm is 0.2 to
1.2 mm (0.01-0.06 in) as shown in the figure.

CRUISE CONTROL SYSTEM 8B-5
Adjustment
1. Check to be sure that the brake pedal has been completely
returned by the return spring.
2. Disconnect the switch connector.







RTW 780SH003301
3. Release the lock 2 by turning the switch 1 counter-clock-
wise.
4. After doing so, pull the pedal arm
3 to you a little so that
the pedal arm is not pushed in.
5. Making the pedal arm not movable with one hand, push in
the whole switch with the other hand until the plunger of the
switch is pushed in and the switch itself hits the rubber o
f
the pedal arm.
In the condition, turn the switch clock-wise until "click"
sound is made and lock it.
By doing this, the switch is adjusted at 0.2 to 1.2mm (0.01-
0.06 in) clearance.

Clutch Switch



Removal and Installation
Refer to the Clutch Control removal and installation procedure
in Clutch section.

Adjustment
1. Turn the clutch switch or stopper bolt 1 until the switch bolt
or stopper bolt just touches the clutch pedal arm.
2.
Adjust clutch switch or stopper bolt by backing it out half a
turn, and measure the clearance (L) between the clutch
pedal arm and the clutch switch bolt end or stopper bolt.
3. Lock the lock nut
2.
4. Connect the clutch switch connector.
