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.

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.

9A-16 SUPPLEMENTAL RESTRAINT SYSTEM




RTW 79ASH000201

Seat Belt with Pretensioner (If so
equipped)
The seat belt comprises a seat belt and a cylinder (a
cylinder filled with powder and an ignition device). In
cases of frontal collision which cause a shock
exceeding a specified level, the controller lets current
flow to the inflation circuit. The current ignites the
cylinder of the seat belt, producing gas. The gas helps
tighten the seat belt to restrain firmly the driver’s uppe
r
half in his seat.




RTW 49JSH000201

Steering Column
The steering column absorbs energy and is designed
to compress in a frontal crash to decrease the chance
of injury to the driver.
060R300038

Knee Bolster
The knee bolsters are used to absorb energy to
protect knees and control the forward movement o
f
the vehicle's front seat occupants during a frontal
crash, by limiting leg movement.

Definitions
Air Bag
An inflatable cloth cushion designed to deploy in
certain frontal crashes. It supplements the protection
offered by the seat belts by distributing the impact load
more evenly over the vehicle occupant's head and
torso.
Asynchronous
Performed in a non-periodic fashion, (i.e., no defined
time or interval).
B+
Battery voltage, (B+) The voltage available at the
battery at the time of the indicated measurement.
W ith the key “ON” and the engine not running, the
system voltage will likely be between 12 and 12.5
volts. At idle, the voltage may be 14 to 16 volts. The
voltage could be as low as 10 volts during engine
cranking.
Bulb Check
The SRS control unit will cause the “SRS” warning
lamp to flash seven times and then go “OFF”
whenever the ignition switch transitions to the ON
position from any other ignition switch position and no
malfunctions are detected.
