BLACKOUT LIGHTING (IF EQUIPPED)
If your vehicle is equipped with blackout lighting it will turn off all
interior and exterior lighting, regardless of ignition position or if any
doors are open.
The switch is mounted on the
instrument panel below the radio.
The courtesy/dome/exterior lights are deactivated when the vehicle is
turned off regardless of which position the blackout lighting switch is in;
these lights are activated when the vehicle’s ignition is turned to
on/auxiliary.
Note:Battery saver mode is enabled when the vehicle is turned off.
There is no delayed timer on this feature.
Note:Black-out lighting will conflict with U.S. Federal Motor Vehicle
Safety Standards (FMVSS). By selecting this option, the
customer/operator has and is exercising Governmental Privilege to
exempt vehicles from full FMVSS compliance.
When blackout lighting is enabled, it will turn off ALL interior
and exterior lights (i.e.headlamps, stop lamps, backup lamps,
interior warning lights, etc). Proceed with caution.

The air coupling, to which the hose
is to be connected, is located on the
floor in front of the rear seat on the
passenger side.
The compressor is controlled by an
instrument panel mounted switch
below the radio. The compressor
cannot be turned on unless the
vehicle ignition is in the ON position
Note:The air compressor uses significant electrical current when
operating. It is recommended that the engine be running when the
compressor is in use to avoid discharging the battery.
When the compressor is switched to the on position, a light in the switch
will be illuminated and the reservoir pressure will increase until it
reaches the pre-set limit. The light will remain on even when the pre-set
pressure limit is reached and the compressor turns off. With the switch
turned on, the compressor may start at any time the ignition switch is in
the ON position. You should turn the compressor switch off until you
plan on using compressed air to avoid possible injuries and minimize
wear on the compressor and system.
Note:When the system is pressurized, all air lines from the compressor
to the outlet chuck are pressurized as well. Do not attempt to work on
the system or loosen any fittings unless you have drained all pressure
from the system by opening the drain on the air reservoir.
Whenever the air compressor has been used, be sure to drain the air
system of all pressure by opening the drain valve at the front of the
reservoir until air no longer escapes.Do not leave the system
pressurized when the vehicle is not in use.This will help to assure
the safety of those who may need to work on the truck and prevent the
condensation of water in the reservoir, extending the life of air system
components.
The air compressor inlet is equipped with a filter to prevent the
ingestion of contamination into the compressor and air system. This filter
is located underneath the truck, by the forward stake pocket on the left
