Ignition Switch and Key

On most vehicles, the ignition switch can be turned
to four positions: ACCESSORY, OFF, ON, and
START. See Fig. 3.1. An optional three-position key-
less ignition switch does not have the ACCESSORY
position.

Fig. 3.1, Ignition Switch Positions
The key can be inserted and removed only from the
OFF position. The headlights (low beams), brake
lights, fog lights, dome lights, clearance lights, turn
signals, hazard warning lights, and the parking lights
operate with the ignition switch in the OFF position,
regardless of whether the key is inserted.
Turn the key fully clockwise to the START position,
only when starting the engine. When the engine
starts, release the key. When released, the key will
rotate counterclockwise to the ON position.
In the ON position (key turned 45 degrees clock-
wise), all electrical systems are operable. The warn-
ing lights and the buzzer for low engine oil pressure
operate until the engine is started and minimum en-
gine oil pressure is achieved.
Electrical System General
Information
The Walk-In Van chassis uses multiple electrical sig-
nals that are carried along a simplified set of wires,
reducing the size of wiring bundles. There are signifi-
cantly fewer wires overall, meaning less chance of
damage, shorts, and other problems. The information

in this chapter is to help familiarize the driver with the
basic electrical system. Servicing the electrical sys-
tem should be done only by qualified technicians.
Special skills and equipment are required. Take the
vehicle to an authorized Freightliner service facility
for repairs.
WARNING
Do not attempt to modify, add, splice, or remove
electrical wiring on this vehicle. Doing so could
damage the electrical system and result in a fire
that could cause serious personal injury or prop-
erty damage.
Battery Disconnect Switch (optional)
Some Walk-In Van chassis may be equipped with a
battery disconnect switch that can be used to prevent
unwanted drain from the vehicle battery when the
vehicle is not in use or is in storage. It can also rap-
idly disconnect from power supplies in the event of
an emergency. Mounting locations may vary. See
Fig. 3.2.
