The Explorer is not designed
nor intended to be used as a
pursuit vehicle or an
ambulance.

to police packages. therefore, the
optional equipment is intended for
use in limited law enforcement
services only. Use of DSO special
service options does not imply nor
allow use as a pursuit vehicle.

Heavy-duty alternator
Handling the high electrical loads
imposed on special service vehicles
by the broad range of necessary
equipment requires a high ampere
output alternator.

ampere alternator, has the voltage
regulator integral with the
alternator. No external voltage
regulator is required.
