The cruise control deactivator switch (which is integral to the BPP switch) is an additional safety feature. When the brake pedal is pressed, an electrical signal is sent from the BPP switch to the PCM deactivating the cruise control system. Under increased brake pedal effort, the cruise control system deactivator switch opens and removes the ground signal from the PCM input circuit, releasing the throttle and immediately deactivating the system.

For vehicles equipped with a manual transmission, the vehicle has a CPP switch. The CPP switch is a normally closed switch with the clutch pedal released. When the clutch pedal is pressed, an electrical signal from the CPP switch opens the circuit and signals the PCM to deactivate the cruise control system.

The CCM monitors the yaw rate signal from the ABS module and compares it to the wheel speed and steering wheel angle signals. If the ABS module determines the yaw rate is invalid, the CCM disables the adaptive cruise control. The message center displays the message COLLISION WARNING MALFUNCTION and/or ADAPTIVE CRUISE MALFUNCTION.

The CCM monitors the environment in front of the vehicle while active. If the radar beam is obstructed by a buildup of snow, ice, rain or other debris, or the vehicle is driven in a desert environment with no other traffic for extended periods of time, the sensor will trigger an "ADAPTIVE CRUISE NOT AVAILABLE SENSOR BLOCKED SEE MANUAL" message in the message center and will disable the adaptive cruise control. The adaptive cruise control will resume once the obstruction is cleared and the radar is able to detect targets, or upon a key cycle.

The adaptive cruise control system will not engage properly if the front radar sensor is not aligned correctly, and the message center will display FRONT SENSOR NOT ALIGNED. The adaptive cruise control will resume once the radar is aligned and is able to properly detect targets.

The ABS module estimates brake temperature by monitoring applied brake pressure over a period of time and sends a message to the CCM when the estimated temperature is above a given threshold. An alarm sounds and the adaptive cruise control system is deactivated until the estimated brake temperature returns to cooler operating conditions. This condition can happen in a hilly or mountainous driving terrain.

Cruise Control Indicator

The adaptive cruise control indicator located in the IPC illuminates a gray indicator lamp and displays the previous gap setting and SET graphic indicating the system is in standby mode. This notifies the driver the system is ready and the vehicle can be accelerated to the desired speed. A green adaptive cruise control indicator illuminates when the system is active.

Steering Wheel Switch Function

The adaptive cruise control steering wheel mounted switches are momentary contact switches that toggle up and down for the cruise control switch state. Pressing and releasing the steering wheel cruise control ON/OFF switch turns the cruise control system on. Pressing up (SET+) and releasing the SET switch sets the vehicle's speed and stores the set speed in memory. The adaptive cruise control indicator illuminates and the message center displays the set speed and gap setting graphic.

There are 2 ways to change the set speed. The first way is to accelerate or brake to the desired speed and press and release the SET cruise control switch until the desired set speed is shown on the message center. The second way is by tapping the SET+ or the SET- switch while in the set mode, increasing or decreasing the displayed set speed by 1.6 km/h (1 mph) per tap. If the respective button is pressed and held, the displayed set speed continues to increase or decrease until the button is released. The adaptive cruise control system may apply the brakes to slow the vehicle down to the new set speed. The set speed displays continuously in the message center while the adaptive cruise control system is active.

Pressing and releasing the OFF switch, or switching the ignition to OFF, turns the adaptive cruise control system off. The adaptive cruise control set speed memory is erased.

Pressing the brake pedal, pressing the clutch pedal (if equipped) or pressing the CNCL switch puts the adaptive cruise control system in standby mode and the last set speed is displayed in the message center with a strike through. Pressing the RES button when the adaptive cruise control system is in standby mode causes the vehicle to accelerate to the last set speed. The set speed continuously displays in the message center while the adaptive cruise control system is active. The RES button does not function if the OFF button is pressed, the ignition is cycled OFF, or if the current vehicle speed is below the minimum operational speed.

The adaptive cruise control system has the capability for the driver to change from adaptive cruise control to standard cruise control. The LH 5-way steering wheel switch is used to switch from the adaptive cruise control system to standard cruise control system within the message center. For information on selecting the standard
