Outside Convex Mirror; Outside Heated Mirrors - GMC 2007 Sierra 1500 Pickup Owner's Manual

Outside 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.
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more
from the driver's seat.

Outside Heated Mirrors

The vehicle may have outside heated mirrors which
helps clear them of condensation, snow, and ice.
The mirror heat is controlled by pressing the
outside mirror button, if the vehicle has a sliding
rear window, or the rear window defogger
button. See "Rear Window Defogger" under Dual
Automatic Climate Control System on page 235
for further information.
The mirror heat will turn off about 10 minutes after
the button is pressed. Press the button again if
additional warming time is needed.
