Description Of Functions

1. This function is controlled by ECM, and operated by throttle body. ECM controls the following functions.

   : ON-OFF, -(COAST)/SET, +(ACCEL)/RES (RESUME), CANCEL, vehicle speed operation

   1. ECM compares the vehicle speed detected by speed sensor and the vehicle speed memorized through the cruise control main switch. When the vehicle speed exceeds the stored vehicle speed, ECM commands the throttle motor of the throttle body to close the valve, on the other hand, when the vehicle speed is lower than the stored vehicle speed, ECM commands to open the valve.
   2. ECM receives signals such as ON-OFF, -SET, +RES, CANCEL through the cruise control main switch to execute these commands.
   3. When the system turns to ON through the cruise control main switch (ON-OFF button), the cruise control indicator in the combination meter ASSY turns green through ECM.
   4. When trouble occurs while driving with the cruise control function ON, the cruise control indicator in the combination meter ASSY turns off or turns yellow through ECM.
   5. When the cruise control main switch turns to -SET while driving, the cruise control SET indicator in the combination meter ASSY turns green through ECM to start the vehicle speed control.

1. Minimum speed

   Possible minimum speed setting is approx. 40 km/h {25 MPH}. When vehicle speed is lower than the minimum speed, the cruise control system cannot be set. When the vehicle speed drops below the controllable speed (approx. 30km/h {20 MPH}) while the cruise control controls the vehicle speed, the speed control deactivates automatically, however the stored vehicle speed will be maintained.

2. Maximum speed

   Possible maximum speed setting is approx. 144km/h {90 MPH}. When vehicle speed exceeds the maximum speed, the cruise control system cannot be set. Also, +(ACCEL)/RES (RESUME) is not available to set the maximum speed higher.

1. In addition to switching the cruise control system to ON/OFF, the cruise control main switch can operate the following seven functions.

   : SET, -(COAST), TAP-DOWN, RES(RESUME), +(ACCEL), TAP-UP, CANCEL

2. SET, -(COAST), TAP-DOWN activate with the switch down, while RES(RESUME), +(ACCEL), TAP-UP activate with the switch up.
3. As the cruise control main switch is an auto return type switch, it is ON while operated in each arrowed direction, and OFF while not operated.
   1. SET control

      When the cruise control main switch is in -SET while driving with the cruise control system in use (the cruise control indicator illuminates green), the vehicle speed is stored and the speed control starts.

   2. -(COAST) control

      When the cruise control main switch is kept pressing to -SET while the cruise control system is controlling the vehicle speed, the cruise control system sends the signal to ECM to operate the throttle valve motor of the throttle with the motor body ASSY, and then the throttle valve is closed. After this, when the cruise control main switch is released, the vehicle speed is stored and maintained.

   3. TAP-DOWN control

      When the cruise control main switch is pressed to -SET (for approx. 0.3 seconds) while the cruise control system is controlling the vehicle speed, the stored vehicle speed is decreased by 1 MPH {1.6 km/h}*1 or 1.0 km/h {0.6 MPH}*2 every time the switch is pressed. When the current and stored vehicle speed differs by 4 MPH {6.8 km/h}*1 or 4.4 km/h {3 MPH}*2 or more with the cruise control main switch pressed to -SET side, the current vehicle speed is stored and the speed control is executed.

   4. Acceleration control

      When the cruise control main switch is kept pressing to +RES while the cruise control system is controlling the vehicle speed, the cruise control system sends the signal to ECM to operate the throttle valve motor of the throttle with the motor body ASSY, and then the throttle valve is opened. After this, when the cruise control main switch is released, the vehicle speed is stored and maintained.

   5. TAP-UP control

      When the cruise control main switch is pressed to +RES (for approx. 0.3 seconds) while the cruise control system is controlling the vehicle speed, the stored vehicle speed is increased by 1 MPH {1.6 km/h}*1 or 1.0 km/h {0.6 MPH}*2 every time the switch is pressed. When the current and stored vehicle speed differs by 4 MPH {6.8 km/h}*1 or 4.4 km/h {3 MPH}*2 or more with the cruise control main switch pressed to +/RES side, the stored vehicle speed does not change.

   6. RESUME control

      When the vehicle speed is approx. 30 km/h {20 MPH} or more after deactivating the cruise control intentionally (except by turning the cruise control ON-OFF switch to OFF), the vehicle speed stored at deactivating is resumed by pressing the cruise control main switch to +RES side.

   7. Shift down control (only AT)

      When the vehicle drives downslope, the transmission shifts down when the actual vehicle speed exceeds the TCM control threshold by the specified value. When the TCM judges that the vehicle can drive according to the stored value, the transmission will shift up.

   8. Intentional cancel operation.

      By performing the following operation, the vehicle speed control by the cruise control is cancelled. (The stored vehicle speed is maintained in ECM.)

      • Brake pedal is depressed.
      • Depress the clutch pedal. (for manual transmission)
      • Shift the shift lever to 1st or R position. (for manual transmission)
      • Shift the shift lever from D or M position to the other position. (for automatic transmission)
      • Select the 1st with the shift lever in M position. (for automatic transmission)
      • Use the shift paddle switch to select the 1st with the shift lever in M (using the shift paddle switch). (for automatic transmission)
      • Pull the cruise control main switch to CANCEL side.
      • Turn the cruise control function to OFF using the cruise control main switch (ON-OFF button) (the stored vehicle speed in ECM will not be maintained).

ECM cancels the cruise control under certain conditions. The cause of cancellation can be confirmed by referring "CANCEL CODE".
