DASH- AND DOOR-MOUNTED CONTROLS
Fog Lights Switch
If your vehicle has fog lights, turn them
ON or OFF with the control panel
switch with the symbol shown above.
NOTE
Across the U.S.A. and Canada,
State/Provincial requirements vary
as to when high beams and fog lights
can and cannot be used together.
Some states allow only four lights to
be used together, while some allow
more. How your lights are arranged
will affect whether you can operate
headlights and fog lights concur-
rently—always comply with the state
or provincial requirements where
you are driving.
Air Suspension Deflate
Switch (Dump Valve)
Your Peterbilt vehicle may have an
air suspension deflation switch which
allows the air in the suspension to be
exhausted from a switch on the dash.
The purpose of this feature is to allow
you to lower your tractor to get under
a trailer. You may notice a guard over
the switch. This prevents you from
accidentally deflating the suspension.
