OPERATING YOUR VEHICLE ACC Operation At Stop If the ACC system brings your vehicle to a standstill while following a target vehicle, if the target vehicle starts moving within two seconds of your vehicle coming to a standstill, your vehicle will resume motion without the need for any driver action. If the target vehicle does not start moving within two seconds of your vehicle coming to a standstill, the driver will either have to press the RES (resume) button, or apply the accelerator pedal to reengage the ACC to the existing Set Speed. While the ACC system is holding your vehicle at a standstill, if the driver seatbelt is unbuckled or the driver door is opened, the parking brake will be activated, and the ACC system will be cancelled. Changing Modes (ACC Only) If desired, the Adaptive Cruise Control mode can be turned off and the system can be operated as a normal (Fixed Speed) Speed Control mode. When in the normal (Fixed Speed) Speed Control mode the distance setting feature will be disabled and the system will maintain the speed you set. • To change between the different cruise control modes, press the ADAPTIVE CRUISE CONTROL (ACC) ON/OFF button which turns the ACC and the normal (Fixed Speed) Speed Control OFF. • Pressing the normal (Fixed Speed) SPEED CONTROL ON/OFF button will result in turning ON (changing to) the normal (Fixed Speed) Speed Control mode. Refer to your Owner's Manual on the DVD for further information. 45
