If the sun comes out or it becomes cloudy, you may need to adjust the HUD brightness again using the dimmer knob. Polarized sunglasses could make the HUD image harder to see. Clean the inside of the windshield as needed to remove any dirt or film that reduces the sharpness or clarity of the HUD image. To clean the HUD, spray household glass cleaner on a soft, clean cloth. Wipe the HUD lens gently, then dry it. Do not spray cleaner directly on the lens because the cleaner could leak into the unit. If the ignition is on and you can't see the HUD image, check to see if one of the following has occurred: Something is covering the HUD unit. The HUD dimmer knob is adjusted properly. The HUD image is adjusted to the proper height. Ambient light (in the direction your vehicle is facing) is low. Accessory Power Outlets With accessory power outlets you can plug in electrical equipment such as a cellular telephone or CB radio. There is a single front power outlet located on the floor console above the climate control system outlets. There is one rear power outlet located in the rear of the vehicle on the driver's side. To use the outlet, pull the cover down. When not using it, cover the outlet with the protective cap. Notice: When using an accessory power outlet, maximum electrical load must not exceed 20 amps. Always turn off any electrical equipment when not in use. Leaving electrical equipment on for extended periods will drain your battery. Certain electrical accessories may not be compatible to the accessory power outlet and could result in blown vehicle or adapter fuses. A fuse is blown. See Fuses and Circuit Breakers on page 5-98. If you ever have to have your windshield replaced, be sure to get one that is designed for the HUD or your HUD image may look blurred and out of focus. 3-20
