Inadvertent Power Battery Saver This feature is designed to protect your vehicle's battery against drainage from the interior lamps, trunk lamp, glove box lamp, cigarette lighters or the garage door opener. When the ignition is turned off, the power to these features will automatically turn off after 10 minutes (three minutes if a new car has 15 miles (24 km) or less). Power will be restored for an additional 10 minutes if any door is opened, the trunk is opened or the courtesy lamp switch is turned on. Night Vision System The optional Night VisionSystem can help you see better when you drive at night. The system works by sensing heat given off by objects in its field of view. Warmer objects, such as pedestrians, animals and other moving vehicles, will appear whiter. Colder objects, such as the sky, signs and parked vehicles, will appear darker. Use this system as an aid to help you in seeing objects beyond the headlamps. Do this by occasionally glancing at the image as you would a rearview mirror. Do not stare at the image. The Night Vision System can be operated if: the instrument panel brightness knob is in any position except OFF it is dark enough outside the headlamps or fog lamps (if equipped) are on and the ignition is turned to ON. 3-22
