System Operation Check

The system operation check is used to check the operating modes of the cruise control system. This procedure should always be used after repair work has been completed on the cruise control system. Step 1) is used with automatic and Manual transmission models, while step 2) is for Manual transmission models only.

Slide the turn signal lever cruise switch to the "ON" position. Check the following;
1. Low Speed Inhibit
  
  Drive the vehicle at 20 MPH (32 km/h). Depress "SET" push button and release. Cruise control must not engage.
2. Set Speed
  
  Drive vehicle at steady speed of 55 MPH (88 km/h). Depress "SET" push button completely and release. Cruise control should engage at approximately 55 MPH (88 km/h).
3. Brake Release
  
  Depress brake pedal. The cruise control must release throttle, allowing the vehicle speed to drop. The system must not engage when the brake is released.
4. Resume Feature
  
  With the vehicle speed at approximately 45 MPH (72 km/h), slide the cruise switch momentarily (less than 1 second) to the "R/A" position. The vehicle should accelerate to approximately 55 MPH (88 km/h).
5. Coast Feature
  
  Depress the "SET" push button and hold. Allow the vehicle speed to drop to 50 MPH (80 km/h) and release push button. Cruise control should hold vehicle speed at approximately 50 MPH (80 km/h).

Slid the turn signal lever cruise switch to the "R/A" position momentarily to resume 55 MPH (88 km/h).
1. Clutch Release
  
  Depress clutch. The cruise control must release throttle, allowing the vehicle speed to drop. The system must not engage when the clutch is released.
2. Off Switch
