Rearview Mirror with Rearview Camera Display On models without navigation system REARVIEW CAMERA DISPLAY If the engine has just been started, it may take a short time for the system to display the rearview. The camera display brightness is adjusted automatically by sensors. If you use the camera display continuously at high temperatures, the image will gradually dim. The rearview mirror will be hot when you use the camera display for an extended period of time. POWER BUTTON You can turn the camera display on and off by pressing the power button when the shift lever is in reverse. The camera display turns on everytime you shift to reverse, even if you turned it off the last time. Whenever you shift to reverse (R) with the ignition switch in the ON (II) position, the rearview appears on a display in the rearview mirror. For the best picture, always keep the rearview camera clean, and do not cover the camera lens. To avoid scratching the lens when you clean it, use a moist, soft cloth. Since the rearview camera display area is limited, you should always back up slowly and carefully, and look behind you for obstacles. If a bright light (such as sunlight) is reflected on the mirror, the image may be difficult to see. 418
