Mirror Heat Switch; Power Window Switch - Peterbilt 348 2017 Operator's Manual

DASH- AND DOOR-MOUNTED CONTROLS

Mirror Heat Switch

Your vehicle may be equipped with
optional heated mirrors. Mirror heat
is controlled by the mirror heat switch
button, which is part of the mirror switch
module located on the driver side door
pad. Motorized mirrors with mirror heat
have an automatic 15-minute "time
3
out" feature, where the mirror heat-only
module is automatically deactivated.
To defrost the mirrors in cold weather,
depress the mirror heat switch button
and release. The mirror heat symbol
in the button will illuminate to indicate
the mirror heat function has been
activated. Pressing and releasing the
3-54
button again turns the mirror heat and
the indicator light Off.
NOTE
The effects of direct sunlight, or the
use of mirror heat, will increase the
outside air temperature displayed
while the vehicle is stationary.

Power Window Switch

Your vehicle is probably equipped with
power windows. Power window rocker
switches are located on the door pads
(a switch for the passenger window is
also on the driver side door pad, as
shown above).
To open or close a window, depress
the switch for that window at the
end that displays a downward- or
upward-directed arrow, respectively, in
the window symbol on the switch face.
Release the switch to stop window
movement.
