The Distance Control Assist (DCA) system helps assist the driver to keep a following distance to the vehicle ahead by braking and moving the accelerator pedal upward in the normal driving condition. When a vehicle is detected ahead : The vehicle ahead detection indicator comes on. When vehicle approaches a vehicle ahead : ● If the driver's foot is not on the accelerator pedal, the system activates the brakes to decelerate smoothly as necessary. If the vehicle ahead comes to a stop, the vehicle decelerates to a standstill within the limitations of the system. ● If the driver's foot is on the accelerator pedal, the system moves the accelerator pedal upward to assist the driver to release the accelerator pedal. When brake operation by driver is required : The system alerts the driver by a warning chime and blinking the vehicle ahead detection indicator. If the driver's foot is on the accelerator pedal after the warning, the system moves the accelerator pedal upward to assist the driver to switch to the brake pedal. The stoplights of the vehicle come on and the brake pedal depresses when braking is performed by the DCA system. When the brake operates, a noise may be heard. This is not a malfunction. Overriding the system : The following driver's operation overrides the system operation. ● When the driver depresses the accelerator pedal even further while the system is moving the accelerator pedal upward, the DCA system control of the accelerator pedal is canceled. ● When the driver's foot is on the accelerator pedal, the brake control by the system is not operated. ● When the driver's foot is on the brake pedal, neither the brake control nor the alert by the system operates. ● When the Intelligent Cruise Control system is set, the DCA system will be cancelled. WARNING ● When the vehicle ahead detection indicator light is not illuminated, system will not control or warn the driver. ● Never place your foot under the brake pedal. Your foot may be caught when the system controls the brake. ● Depending on the position of the accelerator pedal, the system may not be able to assist the driver to release the accelerator pedal appropriately. ● If the vehicle ahead comes to a standstill, the vehicle decelerates to a standstill within the limitations of the system. The system will release brake control with a warning chime once it judges the vehicle is at a standstill. To prevent the vehicle from moving, the driver must depress the brake pedal. (The system will resume control automatically once the system reaches 3 MPH (5 km/h)). Approach warning If your vehicle comes closer to the vehicle ahead due to rapid deceleration of that vehicle or if another vehicle cuts in, the system warns the driver with the chime and DCA system display. Decelerate by depressing the brake pedal to maintain a safe vehicle distance if: ● The chime sounds. ● The vehicle ahead detection indicator blinks. 5-70 Starting and driving
