yellowblue Heated Outside Rearview Mirrors (If Equipped) Your outside mirrors can be defrosted by pressing the button near the fan control. Convex Outside Mirror Your passenger's side mirror may be convex. A convex mirror's surface is curved so you can see more from the driver's seat. 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. An indicator light in the button will illuminate anytime the heated outside rearview mirrors are activated. If your vehicle has a rear window defogger, see "Rear Window Defogger" in the Index. 2-44
