It may also flash red if the ultrasonic sensors are not kept clean. So be sure to keep your rear bumper free of mud, dirt, snow, ice and slush or materials such as paint or the system may not work properly. If after cleaning the rear bumper and driving forward at least 15 mph (25 km/h), the display continues to flash red, see your dealer. For cleaning instructions, see Cleaning the Outside of Your Vehicle on page 5-94. It may also flash red if your vehicle is moving in REVERSE (R) at a speed greater than 3 mph (5 km/h). Other conditions that may affect system performance include things like the vibrations from a jackhammer or the compression of air brakes on a very large truck. As always, drivers should use care when backing up a vehicle. Always look behind you, being sure to check for other vehicles, obstructions and blind spots. There are two accessory power outlets in the rear seat area located on the door armrests next to the ashtrays. Your vehicle may have a small cap that must be removed to access the accessory power outlet. If it does, when not using the outlet be sure to cover it with the protective cap. The accessory power outlet will only operate when the ignition is in ACCESSORY or ON and for 10 minutes after turning the ignition OFF. If you would like the accessory power outlet to operate regardless of ignition position, and for extended periods of time, see your dealer for more information. Notice: Leaving electrical equipment on for extended periods will drain the battery. Always turn off electrical equipment when not in use and do not plug in equipment that exceeds the maximum amperage rating. Certain accessory power plugs may not be compatible to the accessory power outlet and could result in blown vehicle or adapter fuses. If you experience a problem see your dealer for additional information on the accessory power outlets. Accessory Power Outlets Your vehicle is equipped with accessory power outlets. The outlets can be used to plug in electrical equipment such as a cellular telephone, CB radio, etc. If you have a vehicle with a center storage compartment located on the instrument panel, you may have an accessory power outlet in the storage drawer. There is also an outlet on the front passenger's seat near the umbrella tray. 3-29
