When the System Does Not Seem to Work Properly The light may flash red when the vehicle is in REVERSE (R) if the ultrasonic sensors are not kept clean. So be sure to keep your rear bumper free of mud, dirt, snow, ice and slush. 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. If after cleaning the rear bumper and then driving forward at least 15 mph (25 km/h), the display continues to flash red, see your dealer. If a trailer was attached to your vehicle, or a bicycle or an object was on the back of, or hanging out of your liftgate during your last drive cycle, the light may also flash red. The light will continue to flash whenever in REVERSE (R) until your vehicle is driven forward at least 15 mph (25 km/h) without any obstructions behind the vehicle. For cleaning instructions, see Cleaning the Outside of Your Vehicle on page 5-95. 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. Your vehicle has one outlet in front of the center console, one in the rear of the center console, one in the rear compartment, and there may be an additional outlet in the rear of the center console. 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 to OFF. If you would like the accessory power outlet to operate regardless of ignition position, and for extended periods of time, you can do the following: 1. Open the hood and locate the underhood fuse block. 2. Find the I/P OUTLET and OUTLET fuses and move them over a space, to the open cavity next to each fuse. 3-24
