PART 1: INTRODUCTION
T
his manual contains useful information for the safe and
efficient operation of your Peterbilt Model 387. It also pro-
vides information on maintaining your vehicle in the best
condition, with an outline for performing safety checks and
basic preventive maintenance inspections.
We have tried to present the information you'll need to
learn about your vehicle's functions, controls, and opera-
tion—and to present it as clearly as possible. We hope
you'll find this manual easy to use.
Please remember, though—this manual is not a training
manual. It can't tell you everything you need to know
about driving your Peterbilt vehicle. For that you need a
good training program or truck driving school. If you have
not been trained, get the proper training before you drive.
Only qualified drivers should drive this vehicle.
There will be times when you need to take this manual out
of your Peterbilt. When you do, please be sure to return it
to the cab when you are finished using it. That way it will
be there when you need it the next time or when you pass
the vehicle on to the next user.
