yellowblue Convex Outside Mirror Your passenger's side mirror is convex. A convex mirror's surface is curved so you can see more from the driver's seat. Heated Outside Rearview Mirror When you operate the rear window defogger, a defogger also warms the heated driver's and passenger's outside rearview mirrors to help clear them of ice and snow. See "Rear Window Defogger" in the Index. CAUTION: A convex mirror can make things (like other vehicles) look farther away than they really are. If you cut too sharply into the right lane, you could hit a vehicle on your right. Check your inside mirror or glance over your shoulder before changing lanes. Automatic Dimming Outside Rearview Mirror (Option) If you have this feature, the driver's side outside mirror will adjust for the glare of headlamps behind you. This feature is controlled by the on and off settings on the automatic electrochromic day/night rearview mirror. See "Automatic Electrochromic Day/Night Rearview Mirror" earlier in this section. 2-51
