Park Tilt Mirrors If your vehicle has the memory package, the outside mirrors are able to perform the park tilt function. This feature may be useful in allowing the driver to view the curb when parallel parking. 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). The passenger's and/or driver's mirror will return to its original position when the vehicle is shifted out of REVERSE (R), or the ignition is turned off or to OFF/LOCK. This feature can be turned on or off through the Driver Information Center (DIC). See DIC Vehicle Customization (With DIC Buttons) on page 3-68. Convex Mirror {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. The passenger's side mirror may have convex glass. A convex mirror's surface is curved so more can be seen from the driver's seat. Your vehicle may also have a turn signal indicator on the mirror. An arrow on the mirror will flash in the direction of the turn or lane change. Heated Mirrors The button to turn the heated mirrors on or off is located on the climate control panel. Press this button to warm the driver's and passenger's outside rearview mirrors to help clear them of ice, snow, and condensation. See "Rear Window Defogger" under Dual Automatic Climate Control System on page 3-26 for more information. 2-42
