Peterbilt Medium Duty Trucks Operator's Manual after 1-07

Operating Instructions
Power Mirror (Option)
Your Medium Duty may have motorized side mirrors. A switch
for each, located on the dash, controls the adjustment.
To adjust the mirror:
• Push the arrow that points toward the direction you want
to move the mirror.
NOTE: The power mirror switch does not control
the adjustment of the convex mirrors.
Heated Mirrors (Option)
Steering Column and Mirrors
Your vehicle also may have heated mirrors. To defrost mirrors
in cold weather, turn the mirror heat switch to ON.
You can keep the mirror heat on to ensure that the mirrors
stay free of ice or condensation. They automatically adjust to
the temperature outside, providing the right amount of heat to
keep them clear.
