37.5 HEATED / REMOTE CONTROLLED
REAR VIEW MIRRORS
Heated/remote controlled external rear view
mirrors may be provided to prevent the mirrors
from frosting up in cold weather.
The remote controlled external rear view mirrors
attach to support arms using a pivot collar
secured by setscrews. Loosening the setscrews
allows the whole head assembly to turn on the
support arm for initial adjustment. A mounting
bolt and washer hold the arm support to the
mounting bracket. The arm support can be
moved to position the mirror head into or away
from the coach body.
The mirror heat switch is located to the left of the
driver on the dashboard. This switch must be
activated before the mirror heating element will
energize. Once energized, the mirror heating
element is kept at a sustained temperature
(between 60-80°F) by a thermostat. Refer to
wiring diagram annexed
publication box.
CAUTION
Do not attach stick-on type convex mirror
accessories to the heated mirror glass. This
could impede uniform heat distribution on the
mirror surface which could break the mirror.
