Outside Convex Mirror; Outside Heated Mirrors; Onstar System - GMC 2004 Sierra 1500 Pickup Owner's Manual

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.

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 page 3-26 for
further information.
