INTRODUCTION
Vehicle Safety
Make sure your Medium Duty is in top working condition
before heading out on the road—it is the responsible
driver's duty to do so. Inspect the vehicle according to the
“Driver's Check List”, page 83
WARNING! Do not drink and drive. Your
reflexes, perceptions, and judgment can be
affected by even a small amount of alcohol.
You could have a serious—or even fatal accident—if you drive after drinking. Please do
not drink and drive or ride with a d river who
has been drinking.
Please remember, this manual is not a training manual. It
cannot 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.
Every new Peterbilt vehicle is designed to conform to all
Federal Motor Vehicle Safety Standards applicable at the
time of manufacture. Howev er, even with these safety features, continued safe and reliable operation depends
greatly upon regular vehicle maintenance. The vehicle
.
must be operated within the range of its mechanical capabilities and the limits of its load ratings. (See the tire and
rim weight ratings information on the Vehicle Certification
Label on the driver's door frame.) This vehicle is not
approved for off-road operation.
How to Find What You Want
There are several tools built into this manual to help you
find what you need quickly and easily. First is the Contents. Located at the front of the man ual, this lists the main
subjects covered and gives page numbers where you can

A Special Word About Repairs
This is not a repair or workshop manual. Yo ur Peterbilt
Dealer's Service Center is the best place to have your
Medium Duty repaired. You can find Peterbilt dealers all
over the country with the equipment and trained personnel to quickly get you back on the road—and to keep you
there.
Your Medium Duty is a complex machine. Anyone
attempting repairs on it needs good mechanical training,
proper specifications, and proper tools. If you are sure you
meet these qualifications, then you can probably perform
some repairs yourself. But if you are not an experienced
mechanic, anddo not have the right equipment or train ing,
please leave the repairs to an authorized service facility.
They are the ones equipped to do the job safely and correctly.
WARNING! Do not attempt repair w ork without
sufficient training, service manuals, and the
proper tools. You could be killed or injured, or
you could make your vehicle unsafe. Do only
those tasks you are fully qualified to do.
Shop Manuals
If you do decide to do complex repair work, you will need
the Medium Duty Maintenance Manual. It contains ser-
vice procedures, parts information, and suppor ting material on major components in your vehicle, such as
Suspensions, Drivelines, Axles , and the Hea ter/Air Conditioner.
Listed below are manuals available from your Peterbilt
Dealer. (T here is a charge f or these manu als.) Please provide the Chassis Serial Number when ordering, to be sure
you get the correct manuals for your vehicle.
Medium Duty Maintenance Manual. This manual
includes detailed service procedures specifically compiled

CAB AND FRAME ACCESS
Cab and Frame Access
Introduction
The following section covers procedures for accessing the
cab and the frame.
Door Lock and Keys
Doors can be locked from the inside by using the lock button. Close the door then push the button down to lock.
Doors automatically unlock when you open them from
inside, and can be locked from the outside with the key
only.
As standard equipment, two keys are provided for the
doors and ignition. When necessary, additional locks and
keys are provided for storage compartments.
WARNING! To he lp lessen the chance and /or
severity of death or personal injury in case of
an accident, always lock the doors while driving. Along with using the lap shoulder belts
properly, locking the doors helps prevent
doors from inadvertently opening and occupants from being ejected from the vehicle.
To lock or unlock the doors from outside the cab:
• Insert the key in the door lock.
• Tur n the key toward the rear door frame to lock; forward to unlock.
Cab and Frame Access
The following cab and frame entry/exit procedure recommendations were prepared with personal safety foremost
in mind.
WARNING! Do not jump out of the cab or get
into the cab without proper caution. You could
slip or fall, possibly suffering death or serious
injury. You could slip and fall if the steps are
wet or icy, or if you step in fuel, oil, grease,
snow or mud.
To help avoid personal injury due to a slip or fall:
•ALWAYS FACE TORWARDS THE CAB AND USE THREE
POINTS
FOOT
WHENEVER
OF CONTACT (TWO FEET, ONE HAND OR ONE
, TWO HANDS) TO GRIP THE STEPS OR HANDHOLDS
POSSIBLE AND LOOK WHERE YOU ARE GOING.
Medium Duty
(R05/09) Y53-6027 – 9 –
02611
• Use even more care when steps and handholds (or
footwear) are wet, coated with ice, snow, mud, oil,
fuel, or grease.
WARNING! Always reinstall the battery compartment cover (step) before entering the cab.
Without the battery cover you could slip and
fall, resulting in death or possible injury to
yourself.
CAB AND FRAME ACCESS
WARNING! Do not step on vehicle components without antiskid surface s or use components not designed for entry-and-exit use.
You could fall and kill or injure yourself if you
step onto a slippery surface. For example:
• Do not step onto the surface of a fuel tank.
A fuel tank is not a step. The tank surface
can get very slippery, and you might not be
able to prevent a fall.
• Use only the steps and handholds pro vided,
not chain hooks, quarter fenders, etc.
• Do not climb onto and off the deck plate—
use steps and grab handle pro vided. I f there
is no deck plate, or if proper steps and grab
handles are not provided, do not climb onto
the area behind the cab.
• Do not climb onto or stand on the frame
rails. The frame rails are very slippery and
could cause you to fall, result ing in death o r
personal injury.
• Keep steps clean. Clean any fuel, oil, debris,
ice, snow or grease off the steps before
entering the cab or accessing the deck
plate.
