System Controls

When Speed Control (S/C) is selected by depressing the ON/OFF switch on, the PCM allows a set speed to be stored in PCM memory. To store a set speed, depress the SET switch while the vehicle is moving at a speed between 35 and 85 MPH. In order for the S/C to engage, the brakes cannot be applied, nor can the gear selector be indicating the transmission is in Park or Neutral. The S/C can be disengaged manually by:

Stepping on the brake pedal.
Depressing the ON/OFF switch off.
Depressing the CANCEL switch.
Depressing the clutch pedal (if equipped).

NOTE: Depressing the ON/OFF switch off or turning off the ignition switch will erase the set speed stored in the PCM.

For added safety, the S/C system is programmed to disengage for any of the following conditions:

An indication of Park or Neutral.
A rapid increase in engine RPM, indicating that the clutch has been disengaged (if equipped).
Excessive engine RPM, indicating that the transmission may be in a low gear.
The speed signal increases at a rate of 10 MPH per second, indicating that the coefficient of friction between the road surface and tires is extremely low.
The speed signal decreases at a rate of 10 MPH per second indicating that the vehicle may have decelerated at an extremely high rate.

Once the S/C has been disengaged, depressing the RES/ACCEL switch when speed is more than 30 MPH restores the vehicle to the target speed that was stored in the PCM. While the S/C is engaged, the driver can increase the vehicle speed by depressing the RES/ACCEL switch. The new target speed is stored in the PCM when the RES/ACCEL is released. The PCM also has a tap-up feature in which vehicle speed increases at a rate of approximately 2 MPH for each momentary switch activation of the RES/ACCEL switch.

A tap-down feature is used to decelerate without disengaging the S/C system. To decelerate from an existing recorded target speed, momentarily depress the COAST switch. For each switch activation, speed will be decreased approximately one MPH.
