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 219
for more information.
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 has a turn signal indicator on the
mirror. An arrow on the mirror will flash in
the direction of the turn or lane change.
