Mirrors Adjust all the mirrors so you can see clearly when you are sitting in a comfortable driving position. Inside Day/Night Rearview Mirror To reduce glare from headlamps behind you, pull the lever at the bottom of the mirror toward you (to the night position). To return the mirror to the day position, push the lever away from you. Inside Day/Night Rearview Mirror with OnStarR and Map Lamps (If Equipped) This mirror has a lever located at the bottom of the mirror between the two map lamps. This lever is used to change the mirror from day to night position. To reduce glare from headlamps behind you while driving at night, turn the lever 90 degrees. To return the mirror to the day position, return the lever to its original position. There are two map lamps located on the bottom of the mirror. Each lamp is turned on and off by pressing the button next to the lamp. There are also three OnStar buttons located at the bottom of the mirror face. See your dealer for more information on the system and how to subscribe to OnStar. See "OnStar System" in the Index for more information about the services OnStar provides. 2-48
