In an Emergency
Hazard Warning Lights
The hazard warning light switch is located on the
dash in what is referred to as the master module.
See Fig. 23.1. The hazard lights can be activated
regardless of the ignition switch position.
To activate the hazard lights, push the center of the
switch once. The switch will blink at the same rate
that the hazard lights flash. Push the switch again to
turn them off. All the turn signal lights on the vehicle
and trailer, as well as the turn signal indicators in the
ICU, flash simultaneously when the hazard lights are
activated.

Fire Extinguisher
A fire extinguisher is located in the cab by the
driver's door.
Fire in the Cab
The incidence of fire in heavy and medium-duty
trucks is rare, according to data from the National
Highway Traffic Safety Administration. Federal Motor
Vehicle Safety Standard #302 limits the flammability
of specified materials used inside the cab but,
despite this, most materials can burn.
WARNING
Do not allow flames, sparks, or any other heat
sources (such as cigarettes or light bulbs) to
contact materials in the cab. Any materials in the
cab in contact with such heat sources could
cause serious personal injury as well as damage
to the vehicle.
23.1
In Case of a Cab Fire
As quickly as possible, bring the vehicle to a safe
stop, apply the parking brake, turn off the ignition,
and get out of the vehicle.
Emergency Kit, Optional
An optional emergency kit is located in the cab. The
kit includes one or more of the following: a first aid
kit, a reflective vest, a triangular reflector, a flare kit,
and (on vehicles with a Davco fuel/water separator) a
spin-on fuel filter element.
If there is an emergency while driving, cautiously pull
off the road. Turn on the hazard warning lights. Place
the flares and reflector along the side of the road to
alert other drivers that an emergency situation exists.
Use extreme care when placing flares in
emergency situations that involve exposure to
flammable substances such as fuel. An explosion
or fire could occur causing serious personal
injury.
Emergency Filter
f612193a
Replacement, Davco
If the filter cover on the Davco fuel/water separator is
broken, it will not be possible to operate the vehicle.
A standard spin-on filter will correct this problem.
Refer to the Davco web site for additional
information, www.davcotec.com.
To replace the filter on all Davco fuel/water
separators, follow these procedures:
1. Drain the fuel into a suitable container until it is
below the level of the filter collar. See
for the model 382 fuel/water separator.
2.
Remove the filter vent and vent seal.
NOTE: The filter vent and vent seal are not
needed in the emergency replacement. They
should be retained for later installation at the
time when the filter cover is replaced.
3. Using a DAVCO collar wrench, shown in
Fig. 23.3, remove the clear cover and collar.
NOTE: Broken vent cap and collar warranty
claims will not be accepted if any tool other than
a DAVCO collar wrench, p/n 380134 or 382002,
