Cruise Control System Operation WO/ETC

The following cruise control switches disengage the cruise control system:

These switches are mounted on the following components:

When the brake pedal or clutch pedal is depressed, the cruise control system is electrically disengaged.

Electrical disengagement is accomplished by activating the brake cut-out input to the cruise control module. The set speed will be retained in memory when the brakes are activated.

For an automatic transmission only, the stoplamp and TCC switch contains the following items:

The cruise control release switch has a 2-wire cruise control disable connector.

The clutch switch has a 2-wire cruise control disable connector.

The clutch anticipate switch has a 4-wire cruise control disable connector.

Important: The vehicle is equipped with a Set To Get Cruise feature. This requires the operator to use the SET/COAST button before the RESUME/ACCEL slider switch will activate.

The OFF-ON-R/A switch (2) has the following 3 positions:

1. The OFF position
2. The ON position
3. The Resume Acceleration (R/A) position

When the R/A switch is held in for more than 1 second, the system starts the acceleration mode and accelerates the vehicle.

1. Hold in the switch until the desired speed is reached.
2. Release the switch. The vehicle will maintain the selected speed.

For operation of the acceleration mode, ensure that the following 2 requirements are met:

1. Turn the OFF-ON-R/A switch ON.
2. The vehicle is above the minimum speed limit of 40 km/h (25 mph) with a set speed already in memory.

The OFF-ON-R/A switch is used in order to incrementally raise the vehicle speed.

Follow these procedures in order to utilize this function:

1. Engage the cruise control system.
2. Quickly press the OFF-ON-R/A switch (2) towards the R/A position.
3. Quickly release the OFF-ON-R/A switch (2).
4. Tap the OFF-ON-R/A switch (2) in order to increase the speed by 1.6 km/h (1 mph).
5. Do not hold the OFF-ON-R/A switch (2) in the R/A position, the system will engage the accelerator mode.

The cruise control SET/COAST button switch (3) is located in the end of the turn signal multifunction lever. The cruise control SET/COAST button switch (3) has the following 2 positions:

Perform the following steps in order to set the cruise speed:

1. Press the SET/COAST button switch (3) when you have reached the desired speed.
2. Release the SET/COAST button switch (3).

Set Position

Ensure that the following conditions are met:

The system will cruise within 1.6 km/h (1 mph) of the actual selected speed.

The system will cruise until one of the following actions occur:

Pressing the brake pedal will cause the SET/COAST button switch (3) to release. This does not release the resume capability.

Coast Position

Press and hold the SET/COAST button switch (3) in order to lower the vehicle speed. By depressing the SET/COAST button switch (3), the cruise control system is disengaged and allows the throttle to return to the idle position. When the vehicle attains the desired speed, release the SET/COAST button switch (3). The cruise control system will re-engage at this new speed.

Perform the following steps in order to lower the cruise speed in increments of 1.6 km/h (1 mph) using the SET/COAST button switch (3):

1. Quickly press and release the SET/COAST button switch (3).
2. Tap the SET/COAST button switch (3).

Do not hold the SET/COAST button switch (3) in the depressed position, the cruise control system will engage the coast mode.

Use the accelerator pedal in order to override the cruise system.

Release the accelerator pedal in order to return to the previous cruise speed.

Cruise Control System Operation W/ETC

The cruise control operation using the TAC module is through the cruise control function control switches located on the multifunction turn signal lever. The cruise control function control switches includes the ON/OFF, SET/COAST, R/A (resume/accelerate). The switch assembly provides driver control of the cruise control system.

The stop lamp switch, cruise release switch or CPP switch if equipped, is used to disengage the cruise control. A cruise control release switch circuit and a stoplamp switch circuit are used. The stop lamp, cruise release and CPP switches are mounted to the brake pedal bracket . To disengage the system the driver presses the brake pedal or clutch pedal, if equipped. The speed of the vehicle at brake actuation will be stored in the memory of the TAC module.

With cruise control, the vehicle can maintain a speed of about 40 km/h (25 mph) or more without keeping your foot on the accelerator. When the driver turns off the cruise control ON/OFF switch or ignition switch, the cruise control turns off. The vehicle speed stored in the memory of the TAC module will be lost.

When the cruise switch is in the ON position, and the driver presses the SET/COAST button, the TAC module notifies the PCM that the cruise control is requested. The PCM then checks to see that the cruise control enable criteria is met. If the cruise control criteria has been met the PCM sends a class 2 message to the instrument panel cluster (IPC) to illuminate the cruise light, if equipped

The PCM will inhibit cruise control:

If the PCM determines that any of the cruise control inhibit conditions are present, the PCM will disengage the cruise control. The PCM accomplishes this through data communication with the TAC module. If the PCM disables the cruise control for an inhibiting event it will record the reason for disengagement in the Disengage Definition data file Refer to Engine Scan Tool Data Definitions in Engine Controls.
