UNDERSTANDING THE FEATURES OF YOUR VEHICLE 149 NOTE: Clean all four Rear Park Assist Sensors regularly, taking care not to scratch or damage them. The sensors must not be covered with ice, snow, slush, mud, dirt or debris. Failure to do so can result in the system not working properly. The system might not detect an obstacle behind the fascia or it could provide a false indication that an obstacle is behind the fascia. Assure objects are not within 11.8 inches (30 cm) from the rear fascia while driving the vehicle. Failure to do so can result in the system misinterpreting a close object as a sensor problem, causing the ЉSERVICE PARK ASSIST SYSTEMЉ message to be displayed in the instrument cluster. Ultrasonic noise from airbrakes of nearby trucks, air powered jackhammers and air powered shop tools, to name a few, will cause the Rear Park Assist System to be disabled until the ultrasonic noise is no longer present. REAR CAMERA - IF EQUIPPED Vehicles with a Navigation radio may be equipped with a rear view camera (located on the rear liftgate) that allows you to see an on-screen image (on the navigation radio screen) of the rear of your vehicle whenever the vehicle is put into R (Reverse). 3 WARNING! Drivers must be careful when backing up even when using the rear camera system. Always check carefully behind your vehicle, and be sure to check for pedestrians, animals, other vehicles, obstructions, or blind spots before backing up. Failure to do so can result in serious injury or death. If snow, ice, mud, or anything else builds up on the camera lens. Clean the lens, rinse with water, and dry with a soft cloth.
