Outside Automatic Dimming Mirror If the vehicle has this feature, the driver's side outside mirror will adjust for the glare of headlamps behind you. This feature is activated when automatic dimming is turned on the rearview mirror. See Automatic Dimming Rearview Mirror on page 2-42. Outside Heated Mirrors Your vehicle may be equipped with outside heated mirrors. When you operate the rear window defogger, a defogger also warms the heated outside rearview mirrors to help clear them of ice, snow and condensation. See "Rear Window Defogger" under Climate Control System on page 3-19 for more information. Outside Convex Mirror A convex mirror's surface is curved so more can be seen from the driver's seat.

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. Mini Overhead Console 2-44
