UNDERSTANDING THE FEATURES OF YOUR VEHICLE 141 REAR PARK ASSIST SYSTEM- IF EQUIPPED The Rear Park Assist System provides visual and audible indications of the distance between the rear fascia and the detected obstacle when backing up. Refer to the Warning Section and Note Section for limitations of this system and recommendations. The Rear Park Assist System will remember the last system state (enabled or disabled) from the last ignition cycle when the ignition is changed to the RUN/ON position. The Rear Park Assist System can be active only when the shifter is in R (Reverse). If the Rear Park Assist System is enabled at this shifter position, the system will be active until the vehicle speed is increased to approximately 11 mph (18 km/h) or above. The system will be active again if the vehicle speed is decreased to speeds less than approximately 10 mph (16 km/h). Rear Park Assist Sensors The four Rear Park Assist Sensors, located in the rear fascia, monitor the area behind the vehicle that is within the sensors' field of view. The monitored area seems oval in shape. The sensors can detect obstacles from approximately 11.8 inches (30 cm) up to 59 inches (150 cm) from the rear fascia in the horizontal direction, depending on the location and orientation of the obstacle and the type of obstacle. 3
