Night Vision System (Option) The Night Vision System 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: D The instrument panel brightness knob is in any position except OFF D it is dark enough outside, D the headlamps or fog lamps (if equipped) are on and D the ignition is turned to ON. 2-130
