Outside Convex 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. Outside Heated Mirrors The vehicle may have outside heated mirrors which helps clear them of condensation, snow, and ice. There is a heated mirror symbol on the driver's side mirror that indicates the feature. When the rear window defogger button is pressed, the heated mirrors are turned on. See "Rear Window Defogger" under Dual Automatic Climate Control System on page 3-25 for further information. {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.
