162 UNDERSTANDING THE FEATURES OF YOUR VEHICLE CAUTION! • The Rear Park Assist system is only a parking aid and it is unable to recognize every obstacle, including small obstacles. Parking curbs might be temporarily detected or not detected at all. Obstacles located above or below the sensors will not be detected when they are in close proximity. • The vehicle must be driven slowly when using the Rear Park Assist system to be able to stop in time when the obstacle is detected. It is recommended that the driver look over his/her shoulder when using the Rear Park Assist system. NOTE: • Ensure that the rear bumper is free of dirt and debris to keep the system operating properly. • Jackhammers, large trucks, and other vibrations could affect the performance of the system. Enable/Disable The Rear Park Assist System There are times when you may want to disable the Rear Park Assist system, such as when towing a trailer. The system can be turned ON or OFF through the Electronic Vehicle Information (EVIC) - if equipped. Refer to "Personal Settings (Customer Programmable Features)" under "Overhead Console with Electronic Vehicle Information Center (EVIC) - If Equipped" in Section 3. Service The Rear Park Assist System When the Rear Park Assist System is defective, the EVIC will display the "SERVICE PARK ASSIST SYSTEM" message along with a single chime once per ignition cycle. Refer to "Electronic Vehicle Information Center (EVIC)" in Section 3 of this manual. The Park Assist display will also light the red led's indicating a problem. Under this condition the Rear Park Assist System will not operate.
