Outside Curb View Assist Mirrors If your vehicle has the optional memory package you may have this feature. The vehicle's mirrors are capable of performing the curb view assist mirror function. This feature will cause the passenger's and/or driver's mirror to tilt to a preselected position when the vehicle is in REVERSE (R). This feature may be useful in allowing you to view the curb when you are parallel parking. When the vehicle is shifted out of REVERSE (R) and a short delay has occurred, the passenger's and/or driver's mirror will return to its original position. To change the preselected tilt position, adjust the mirrors to the desired position while the vehicle is in REVERSE (R). When the vehicle is shifted out of REVERSE (R), this new position is saved in memory as the tilt position. You may be able to enabled/disable this feature through the Driver Information Center. See Driver Information Center (DIC) on page 3-50. 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. A convex n...:or can r ,.ngs (I ! 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 your over shoulder before changing lanes. Outside Heated Mirrors The outside rearview mirrors with this option have a defrost mode. To turn on the defrost feature, press the rear window defogger button. See Rear Window Defogger under Dual Automatic Climate Control System on page3-24 for further information. 2-60
