RAM 1500 2018 Service Supplement Manual - page 6
INTRODUCTION
This booklet is a supplement to the Owner’s Manual
prepared with the assistance of service and engineering
specialists, and is intended to aid the operators of Special
Service vehicles (used in severe duty, high-mileage opera-
tions) in understanding the operation and required main-
tenance procedures for such vehicles. It covers mainte-
nance procedures for vehicles equipped with heavy-duty
packages. However, other vehicles operated under the
conditions listed below are also considered “severe ser-
vice” vehicles, and should be serviced and maintained as
prescribed in this booklet. You are urged to read this
publication and the Owner’s Manual carefully.
This vehicle is equipped with a Vehicle Systems Interface
Module (VSIM), a 24-way connector, and four additional
connectors. The VSIM and connectors allow the vehicle to
be upfitted with aftermarket equipment. For further infor-
mation, please refer to the upfitters information.
Following the instructions and recommendations provided
herein, will help assure safe and reliable operation of your
vehicle. After you have read the booklet, it should be stored
in the vehicle for convenient reference and remain with the
vehicle when sold.
When it comes to service, remember that your authorized
dealer knows your vehicle best, has factory-trained techni-
cians and genuine MOPAR® parts, and cares about your
satisfaction.
