Outside Convex Mirror; Outside Heated Mirrors - GMC 2010 Sierra Denali Owner's Manual

Outside Convex Mirror

WARNING:
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 the right. Check the inside mirror
or glance over your shoulder before changing
lanes.
The passenger side mirror is convex shaped. A convex
mirror's surface is curved so more can be seen from the
driver seat.
