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.

Accessory Power Outlet(s)

Your vehicle may be equipped with a front accessory power outlet located below the climate controls on

the instrument panel. It can be used to plug in electrical equipment such as a cellular telephone or CB radio.

Pull the cover down to use the accessory power outlet. When not in use, keep the cover on.

The rear accessory power outlet is located on the rear compartment on the driver’s side.

To remove the cover, pull the tab on the cover and pull it off. To put the cover back on, line up the tabs at the back of the cover and put the cover in place. Push down the tab to secure the cover. When not in use, always cover the rear accessory power outlet with the protective cap.

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 electrical accessories may not be compatible with 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 accessory power outlets.
