OPERATING YOUR VEHICLE The ACC Warning • The ACC Blinded message will display in the EVIC when conditions temporarily limit the system performance and the system will be deactivated. The most likely cause for a deactivated system is a dirty or obstructed sensor, occurring mostly during snow, fog, heavy rain, or by obstruction from dirt or ice. In these cases, the EVIC will display "ACC BLINDED." Examine the sensor (behind the grille, slightly offset from the center of the grille) which may need simple cleaning, or removal of the obstruction. System Maintenance • Always keep the sensor clean for optimum system performance. • See your authorized dealer for services if the sensor is damaged. • Do not attach or install any accessories near the sensor, including transparent material or aftermarket grilles. Doing so could cause an ACC system failure or malfunction. • Refer to your Owner's Manual on the DVD for complete details. MANUAL CLIMATE CONTROLS Air Recirculation • Use recirculation for maximum A/C operation. • For window defogging, turn the recirculation off. • Recirculation is not allowed in defrost, floor, defrost/floor (mix) modes. 27
