Outside Convex Mirror; Outside Heated Mirrors; Onstar System - GMC 2003 Yukon Owner's Manual

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 3-53 .

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.
{
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.
