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.

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.

Engine Oil Pressure Gauge
It is important to maintain oil pressure within acceptable
limits. Your engine manual will give normal operating pressures for your engine.
CAUTION: Continuing to operate your vehicle
with insufficient oil pressure will cause serious
engine damage.
• If your oil pressure fails to rise within 10 seconds after
your engine starts, stop the engine and de te rmine the
cause.
• If your oil pressure suddenly drops while you are driving, bring the vehicle to a stop as soon as possible in
a safe location off the road and turn off the engine.
Wait a f ew min utes to allow oil to dr ain into the oil pan,
and then check the oil le v el. Add oil if necessary. If the
problem persists, contact an authorized service center.
Check the engine manufacturer’s manual for the correct
oil pressure ranges for your engine.
Water Temperature Gauge
The water temperature gauge shows the temperature of
the engine coolant. Under normal operating conditions the
– 40 –Y53-6027
Medium Duty(R05/09)
CONTROLS AND DISPLAYSTANDARD GAUGES
water temperature gauge should register between 165°
and 205°F (74° and 90°C). Under cer tain conditions,
somewhat higher temperatures may be acceptable. But
the maximum allowable temperature is 210°F (99°C) with
the cooling system pressurized, except for certain special
engines. Check your engine manual to be sure.
Engine Overheating
WARNING! Stop the vehicle in a safe location
if the engine temperature gauge indicates an
overheating situation. Fai lure to park the ve hicle in a safe location may result in death, personal injury or property damage.
Wait until the coolant temperature is below 122° F (50°C).
Protect your face, hands, and arms by covering the cap
with a large, thick r ag to prot ect y ou against escaping flu id
and steam. Before you completely remove the cap, carefully and slowly turn the cap part way to allow excess
pressure to escape. Then push down and turn for final
removal.
The cooling system may overheat if the coolant level is
below normal or if there is a sudden loss of coolant (such
as a worn hose splitting). It may also temporarily overheat
during severe operating conditions such as climbing a
long hill on a hot day or stopping after high-speed driving.
WARNING! Do not remove the radiator fill cap
while the engine is hot. Scalding steam and
fluid under pressure may escape and cause
death or serious personal injuries. You could
be badly burned.
• Wait until the coolant temperature is below
122°F (50°C).
• Protect face, hands, and arms by covering
the cap with a large, thick rag to protect
against escaping fluid and steam.
• Carefully and slowly turn the cap one-quarter of a turn or until it reaches the first stop—
allowing excess pressure to escape—push
down and turn for final removal.
If the “Engine Coolant Temperature” warning light comes
on, or you have any other reason to suspect the engine
may be overheating:
• Stop the vehicle, but DO NOT TURN OFF THE
ENGINE unless a low water warning device indicates
a loss of coolant.

• With the transmission in neutral, check to be certain
the oil pressure gauge reads normal. Increase the
engine speed to about 1100 - 1200 RPM, maximum.
Return the idle speed to normal after 2 or 3 minutes. If
the warning light does not go off or the temperature
gauge does not begin to drop, then turn the engine

• Be sure, also, that your belt is not too loose. A loose
belt could allow you to slide under it in an accident,
and that could bring the belt up around your abdomen.
• Do not twist the belt in the process of putting it on. A
twisted belt will not work as well to protect you.
WARNING! Always wear your seat belt low
over your pelvic bones.
• You can be kille d or seriousl y injured if y our

apply force to your abdomen, not your pelvic bones. This can result in death or serious internal injuries.
• Do not drive with your seat belt loose. A
seat belt that is too loose can allow you to
fall too far forward, possibly causing head
and neck injuries, resulting in death or personal injury. You could strike the wheel or
the windshield. Adjust your belt so that
there is no more than 1 in. (25mm) of slack.
WARNING! Do not wear the shoulder belt
under your arm or otherwise out of position.
In a crash your body would move too far forward, increasing the chance of death or head
and neck injury. Also, the belt would apply to o

to suffer internal injuries. Wear the shoulder
belt over your shoulder (see “Safety RestraintBelts” on page 75).
WARNING! Do not twist the belt in the process
of putting it on. A twisted belt will not work as
well to protect you . In a crash, t he full width of
the belt would not be protecting you. A
twisted belt could cut into your body and
cause death or serious injuries. Straighten the
belt before buckling it. If you are unable to
wear it without twisting it, have your dealer or
service person repair it as soon as possible.

Safety Restraint Tips
NOTE: Per FMCSR 392.60 - Unauthorized Persons Not to be Transpor ted. Federal law prohibits the transportation of persons in commercial
vehicles unless they are specifically authorized
in writing by the motor carrier. See the cited
FMCSR for a complete description of the regulation and exemptions.
• Any authorized person riding in your vehicle should
wear a seat belt. A responsible operator sees to it that
everyone in the vehicle rides safely—and that means
with a seat belt.
• Do not strap in more than one person with each belt.
• Do not wear a belt over rigid or breakable objects in or
on your clothing, such as eye glasses, pens, keys,
etc., as these may cause injury in an accident.
• Several layers of heavy clothing may interfere with
proper positioning of belts and reduce the overall
effectiveness of the system.
• Keep belt buckles free of any obstruction that may
prevent secure locking.
• Damaged or worn belts, subjected to excessive
stretch forces from crashes, cuts or tears, or normal
wear, must be replaced—they may not protect you if
you have an accident.
• If belts show damage to an y part of assembly, such as
webbing, bindings, buckles or retractors, they must be
replaced.
• Do not allow safety belts to become damaged by getting caught in door or seat hardware, or rubbing
against sharp objects.
• The belts must be kept clean or th e retract ors ma y not
work properly.
• Never bleach or dye seat belts: chemicals can
weaken them. Do, however, keep them clean by following the care label on the belts. Let them dry completely before allowing them to retract.
• Make sure the belt of the unoccupied passenger seat
is fully wound up on its retractor, so that the belt
tongue is in its stowed positi on. Th is re duces the po ssibility of the tongue becoming a striking object in
case of a sudden stop.
• Do not modify or disassemble the seat belts in your
vehicle. They will not be available to keep you and
your passengers safe.

• If any seat belt is not working properly, see an Authorized Service Center for repair or replacem e nt .
WARNING! Before driving or riding in a vehicle, ensure that there is adequate head clearance at maximum upward travel of seat.
Shorten the tether belt as nece ssary to provide adequate head clearance. Death or serious injury may occur if head clearance is not
adequate.
Tether Belts
Tether belts are installed on suspension seats. They help
secure the seat to the floor to restrain it in case of a sudden stop or an accident.
Fixed Tethers
If your Medium Duty v e hicle has been equ ipped wit h f ixed
length tethers, no manual adjustment is re quired. The
same inspection and replacement guidelines should be
used as stated on page 197.
WARNING! Do not remove, modify, or replace
the tether belt system with a different tether
system. A failed or missing tether belt could
allow the seat base to fully extend in the event
of an accident leading to greater injuries or
death.
WARNING! Failure to adjust tether belts properly can cause excessive movement of the
seat in an accident. This could lead to death
or greater injuries to you. Tether belts should
be adjusted so that they are taut when the
seat is in its most upward and forward position.
Tether Adjustment
• Make sure that the tether belt is attached to the cab
floor and seat frame. It should be routed through the
buckle on each side.
• Often the attachments are made using a split-type
hook. Make sure both halves of the hook are a round
the anchor bracket.
• To lengthen the tether, turn the buckle to a right angle
to the webbing. Then pull the buckle. To shorten the
tether, pull on the strap.

Komfort–Lok® Latch
Your Peterbilt contains a feature designed to eliminate
cinching and provide improved safety and comfort. Cinching is the condition where a belt becomes continually
tighter around you during a rough, bouncy ride. The need
for this feature increases with rough road conditions, particularly over long distances. To eliminate cinching, simply
activate the Komfort–Lok®
1. Fasten the seatbelt according to the directions in the
previous “Safety Belt Restraint” section.
2. You are now ready to activate the Komfort–Lok. Lean
forward to pull a little slack in the belt (maximum of
one inch, measured from the belt to your chest). Be
sure to allow only a small amount of slack.
3. When the slack is right, flip the latch cover up, cinching it into place.

During Pregnancy
Pregnant women should always wear combination lap/
shoulder belts. The lap belt portion must be worn snugly
and as low as possible across the pelvis. To avoid pressure on the abdomen, the belt must never pass over the
waist. Sometimes pregnant women worry that in a crash
the seat belt could hurt the baby. But if a woman wears
her belt properly—low over her pelvis, below her abdomen—the belt will not harm the baby, even in a crash. And
remember—the best way to keep an unborn baby safe is
to keep the mother safe.
Passengers
Anyone riding in your vehicle should wear a seat belt. A
responsible operator sees t o it that e v eryone in the ve hicle
rides safely—and that means with a seat belt.

Safe Vehicle Operation
To keep your Medium Duty vehicle in top shape and maintain a high level of safety for you, your passengers, and
your load, make a thorough inspection every day before
you drive. You will save maintenance time later, and the
safety checks could help prevent a serious accident.
Please remember, too, that the F ederal law requires a pretrip inspection and so do commercial trucking companies.
You are not expected to become a prof ession al mechan ic.
The purpose of your inspections is to find anything that
might interfere with the safe and efficient transportation of
yourself, any passengers, and your load. If you do find
something wrong and cannot fix it yourself, have an
Authorized Service Center or qualified mechanic repair
your vehicle right away.
The following operations are to be performed by the
driver. Performing these checks and following the maintenance procedures in this manual will help keep your
Medium Duty vehicle running properly.
For your safety, as well as those around you , be a responsible driver:
• If you drink, do not drive.
• Do not drive if you are tired, ill, or under emotional
stress.
Much has gone into the manufacturing of your Medium
Duty vehicle, including advanced engineering techniques,
rigid quality control, and demanding inspections. These
manufacturing processes will be enhanced by you—the
safe driver—who:
• knows and understands how to operate the vehicle
and all its controls
• maintains the vehicle properly
• uses driving skills wisely
For more information, refer to Department of Transportation Regulation 392.7, which states that interstate commercial motor vehicles are not to be driven unless the
driver is sure that certain parts and accessories are in
working order.

DRIVER'S CHECK LIST
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—even fatal—accident if you drive after drinking. Please do not
drink and drive or ride with a driver who’s
been drinking.
• The use of alcohol, drugs, and certain medications will seriously impair perception,
reactions, and driving ability. These circumstances can substantially increase the risk
of an accident and death or serious personal injury.
Vehicle Loading
Compare your vehicle's load capacity with the total load
you are carrying. If adjustments need to be made, make
them—do not drive an ov erloaded vehicle. If you are o v erloaded or your load has shifted, your vehicle may be
unsafe to drive.
WARNING! Do not exceed the specified load
rating. Overloading can result in loss of vehicle control and death or serious personal
injury, either by causing component failures
or by affecting vehicle handling. Exceeding
load ratings can also shorten the ser vice life
of the vehicle.
• The components of your vehicle are
designed to provide satisfactory service if
the vehicle is not loaded in excess of either
the gross vehicle weight rating (GVWR), or
the maximum front and rear gross axle
weight ratings (GAWRs). (Axle weight ratings are listed on the driver's door edg e.)
Here are some definitions of weight you should know:
GVWR:is the Gross Vehicle Weight Rating. This is the
MAXIMUM WEIGHT your vehicle is allowed to carry,
including the weight of the empty vehicle, loading platform, occupants, fuel, and any load. Never exceed the
GVWR of your vehicle.
GCW:is the actual combined weight, or Gross Combina-
tion Weight (GCW), of your vehicle and its load: tractor,
plus trailer(s), plus cargo.
– 84 –Y53-6027
Medium Duty(R05/09)
DRIVER'S CHECK LIST
GAWR:is the Gross Axle Weight Rating. This is the total
weight that one axle is designed to tr ansm it to t he g rou nd.
You will find this number listed on the driver's door edge.
Load Distribution: be sure any load you carry is distrib-
uted so that no axle has to support more than its GAWR.
WARNING! An unevenly distributed load or a
load too heavy over one axle can affect the
braking and handling of your vehicle, which
could result in an accident causing death or
personal injury. Even if your load is under the
legal limits, be sure it is distributed evenly.
Emergency Equipment
It is good practice to carry an emergency equipment kit in
your vehicle. One day, if you have a roadside emergen cy,
you will be glad the following items are with you:
• window scraper
• snow brush
• container or bag of sand or salt
• emergency light
• small shovel
• first aid kit
• fire extinguisher
Approaching Your Vehicle
• Check the overall appearance and condition. Are windows, mirrors, and lights clean and unobstructed?
• Check beneath the ve hicle. Are th ere signs of fuel, oil,
or water leaks?
• Check for damaged, loose, or missing parts. Are there
parts showing signs of excessive wear or lac k of lubrication? Have a qualif ied mechanic e xamine an y questionable items and repair them without delay.
• Check your load. Is it secured properly?

STARTING AND OPERATING THE VEHICLE
Starting and Operating the Vehicle
Introduction
For detailed information on starting and operating the
engine, refer to the Engine Operation and MaintenanceManual provided with your Medium Duty vehicle.
Because each vehicle is custom-equipped, all engine
operation instructions presen ted in this section are general. You will want to consult the engine manual to find out
details about your vehicle's specific engine requirements.
You may need to use a slightly different procedure from
the one outlined here.
Also, read the American Trucking Association's (ATA)
Tr uck Driver's Handbook. It will give you tips on starting,
shifting, and driving your vehicle.
WARNING! Do not use ether or other starting
fluids as a cold-starting aid in your Medium
Duty vehicle. Your engine uses either an electrical grid or an open flame inside the manifold, to heat the air/fuel mixture for cold
weather starting. If ether or another starting
fluid is used, the air/fuel will ignite inside the
manifold, which cou ld cause an e xplosion and
death or severe injury.
WARNING! Do n ot start or let the engine run in
an enclosed, unventilated area. Exhaust
fumes from the engine cont ain carbon mono xide, a colorless and odorless gas. Carbon
monoxide can be fatal if inhaled.
• Do not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, spilled fuel or
other material that can cause a fire.
Medium Duty

STARTING AND OPERATING THE VEHICLE
CAUTION: The use of a winterfront can result
in excessive engine coolant, oil, and charge
air (intake) temperatures, which can lead to
overheating and possible engine damage. If
you must use a winterfront
• Refer to the “Engine Operation and Maintenance Manual” for operating restrictions
and recommendations.
• Use only a winterfront available from your
Peterbilt dealer that is compatible with a
2002 EPA-compliant engine cooling syste m.
These winterfronts are specifically designed
for use with new grill snap patterns.
Starting Procedure — Normal Temperatures
Use the following procedure to start your Medium Duty
vehicle when outside temperatures are at or ABOVE normal starting temperatures. Check the Engine Operationand Maintenance Manual for starting temperatures.
1. Set the parking brake.
NOTE: When any one of the follo wing is true, oil
should be applied to the turbocharger oil inlet
port: (1) if the engine has not been star ted for
more than 25 days; or (2), the outside temperature is very cold; or (3), the oil filter has been
changed.
•With an oil can, squirt approximately one-half
cup (120 ml) of clean, specified engine oil into
the turbocharger oil inlet port. This will keep the
turbocharger bearings lubr icated until the
engine oil pressure gets up to normal.
2. Insert key into the ignition switch.
3. Disable (or turn OFF) the following systems prior to
starting the engine: the exhaust br ake , the dual-speed
rear axle (put in LO W), and block heater (if equipped).
4. Disengage the transmission: place the shift lever in
the Neutral position.
5. Disengage (depress) the clutch (with manual transmission).
6. T urn the ignition switch to the IGN & A CC position. F or
normal temperatures, no accelerator advance is necessary. See “Use of Accelerator” below. If the “WAIT
– 90 –Y53-6027
Medium Duty(R05/09)
STARTING AND OPERATING THE VEHICLE
TO START” indicator lamp turns ON, wait until the
indicator lamp goes OFF (approximately 60 seconds)
before attempting to start the engi ne. (For each
engine and ambient temperatures, warm-up cycles
will vary.)
7. Turn the ignition switch to the IGN & START position
to engage the starter. Crank the engine until it starts.
If the engine does not start within 30 seconds, release
the key.
Use of Accelerator
• For mild to warm temperatures above 60°F (16°C)
keep your f oot OFF the accelera tor pedal while cran king. If the engine does not start after 5 seconds, a pply
full throttle while cranking.
• For below normal starting temperatures fully depress
the accelerator (throttle) pedal after engaging the
starter.
NOTE: Pumping the accelerator will not assist in
starting the engine.
CAUTION: To help avoid overtaxing the starter
motor or batteries, or causing engine damage,
follow the recommendations listed below:
• Do not engage starter for more than 30 seconds at a
time.
• Wait two minutes between each attempt to star t the
engine. This allows the starter motor to cool and time
for the batteries to regain power.
• If the engine fails to start after a couple of tries, there
could be a malfunction with the engine or othe r
related system. Make any adjustments or repairs necessary before trying to start the engine again.
When the engine starts:
• Watch the oil pressure gauge. Oil pressure should
rise within 15 seconds after the engine starts. If the oil
pressure does not rise, stop the engine. Find what is
wrong before restarting. Check the Engine Operationand Maintenance Manual for the right o il pressure for
your vehicle's engine. In most engines, idle pressure
should be about 15 psi.
Medium Duty
(R05/09)Y53-6027– 91 –
STARTING AND OPERATING THE VEHICLE
CAUTION: Never operate the starter motor
while the engine is running. The starter and
flywheel gears could clash or jam, severely
damaging them.
• Wait until normal engine oil pressure register s on the
gauge before idling or acceler ati ng the engine be y ond
1000 rpm.
• Watch the air pressu re gauge. Wait until both pointe rs
register at least 100 psi (689 kPa) before releasing the
spring brake and moving the vehicle. Also, check the
alarm system for any type of faults and correct them
before moving the vehicle.
CAUTION: Do not try to put the vehicle in
motion before pressure in the air system
reaches 100 psi (689 kPa) because the wheels
will still be locked by the spring brake action.
• Unnecessary stress and possible brake
malfunction could occur if the vehicle is
forced to move before the air system
reaches 100 psi (689 kPa).
Starting Procedure — Cold Temperatures
In addition to the previous “Normal Star ting Pro cedures,”
use these Cold Weather Starting g uidelines when the air
temperature falls below a certain temperature. Check your
Engine Operation and Maintenance Manual for f ur t he r
details on when cold weather star ting aids are needed.
Using special cold-starting equipment will help the engine
start easier. And in cold weather, fast engine starting
helps relieve the loads on the electrical system and cranking motor. If you follow these few simple guidelines, you
will extend the service life of your vehicle's engine:
• Keep the electrical system in top condition.
• Use the best quality and recommended grade of fuel
(see Engine Operation and Maintenance Manual).
• Use the recommended engine lubricating oil.
• As stated in the Normal Starting Procedures, when
temperatures are below normal, fully depress the
accelerator pedal after engaging the starter.
– 92 –Y53-6027
Medium Duty(R05/09)
STARTING AND OPERATING THE VEHICLE
Engine Block Heater (Option)
To preheat the engine before starting, plug the optional
engine block heater into a properly grounded AC electrical
source. Do not start the engine with the heater plug ged in.
WARNING! Engine block heaters can cause
fires resulting in death or serious personal
injury and/or property damage if not properly
maintained and operated. Regularly inspect
the engine block heater wiring and connector
for damaged or frayed wires. Do not use the
heater if there are any signs of problems. Contact your Authorized Service Center or the
manufacturer of the heater if you are in need
of repairs or information.
CAUTION: Always unplug the heater before
starting the engine. Damag e to the cooling
system could occur if the heater is not turned
OFF (unplugged).
When the temperature falls below 0°F (–18°F) for Caterpillar engines, or –10°F (–24°C) for Cummins engines, the
block heater is required.
• Use a solution of half ethylene glycol antifreeze and
half water fo r best heater performance. Do not exceed
60 percent concentration of antifreeze, as it can
shorten heater life. See page 146 for more information.
• After servicing the cooling system, operate the v ehicle
for a day or two before using the heater. Trapped air
inside the engine needs time to escape.
Cold Weather Starting—Air Intake Heater
Do not use ether or any other starting fluid as a cold starting aid in your Medium Duty vehicle. Engine conditions
are automatically monitored and in cold weather the fuel/
air mixture is preheated in the manifold.
WARNING! Do not use ether or other starting
fluids as a cold-starting aid in your Medium
Duty vehicle. Your engine uses either an electrical grid or an open flame inside the manifold, to heat the air/fuel mixture for cold
weather starting. If ether or another starting
fluid is used, the air/fuel will ignite inside the
manifold, which cou ld cause an e xplosion and
death or severe injury.
Medium Duty
(R05/09)Y53-6027– 93 –
STARTING AND OPERATING THE VEHICLE
With each engine make, the air intake heating system
works differently. To u nderstand fully how your engine's
heating system operates, see the engine Operation and
Maintenance Manual for details.
On most systems the engine block temperature is monitored at startup; other systems monitor the engine oil
pressure, coolant temperature, and time, as well. When
the pre-set conditions are met, the heater automatically
engages.
Air Intake Heater
The air intake heater system will alert you when the
engine requires preheat. On the dash is a “WAIT TO
START” warning light (See page 28
). This light alerts you
to wait before starting the engine.
Turn the key to IGN & ACC: the WAIT TO START light will
light up for bulb check.
Wait until the WAIT TO START light goes off before you
start the engine.
When the WAIT TO START light goes off, the preheat
cycle is complete and you can start the engine normally.
After the engine starts and until operating cond itions
reach a certain po int, the system will continue to o perate
to eliminate white-smoke exhaust.
Engine Warm–Up and Idling
The purpose of engine warm-up is to allow an oil film to be
established between pistons, shafts, and bearings while
your engine gradually reaches operating temperature.
Warm–Up Procedure
1. After you have started the engine, idle the engine at
approximately 600 rpm while you check vital engine
systems:
– oil pressure
– air pressure
– alternator output (with the optional voltmeter)
2. Before placing engine under a load, continue warmup with the engine at 900 to 1000 rpm for 3 to 5 minutes.
• When a cold engine is started, increase the engine
speed (rpm) slowly to be sure adequate lubrication
is available to the bearings and to allow the oil pressure to stabilize. In extremely cold temperatures,
you may have to increase idle speed.
– 94 –Y53-6027
Medium Duty(R05/09)
STARTING AND OPERATING THE VEHICLE
NOTE: In colder climates where the temperatures are often below freezing, sufficient war mup for turbocharged engines is especially important. Chilled external oil lines leading to the turbocharger will slow the oil flow until the oil
warms, reducing oil available for the bearings.
Watch the engine oil pressure gauge for a
warming trend before increasing engine idle
speed (rpm).
3. Cont inue the engine warm-up until the coolant temperature reaches at least 130°F (54°C). At this temperature, you can use partial throttle. Wait until the
coolant temperature is at least 160°F (71°C) before
operating at full throttle. See “Operating Manual
Transmissions” on page 98.
WARNING! Exhaust fumes from the engine
contain carbon monoxide, a colorless and
odorless gas. A poorly maintained, damaged,
or corroded exhaust system can allow carbon
monoxide to enter the cab or sleeper. Failure
to properly maintain your vehicle could cause
carbon monoxide to enter the cab and cause
death or serious illnesses.
WARNING! Never idle your vehicle for prolonged periods of time if you sense that
exhaust fumes are entering the cab. Investigate the cause of the fumes and correct it as
soon as possible. If the vehicle must be driven
under these conditions, drive only with the
windows slightly open. Failure to repair the
source of the exhaust fumes may lead to
death, injury or serious illness.
Idling the Engine
Under most circumstances, continuous idling of your
engine merely wastes fuel. In se vere Ar ctic weather conditions, however, you may need longer idling to be sure all
parts of your engine are fully lubricated.
CAUTION: Do not allow your engine to idle, at
low rpm (400–600 rpm), longer than five minutes. Long periods of idling after the engine
has reached operating temperatures can
decrease engine temperature and cause
gummed piston rings, clogged injectors, and
possible engine damage from lack of lubrication. The normal torsional vibrations generated can also cause transmission wear.
Medium Duty
(R05/09)Y53-6027– 95 –
STARTING AND OPERATING THE VEHICLE
• During the time it takes you to drink a cup of coffee,
your engine can cool as much as 60° F (33° C) below
normal operating temperature. To keep the engine
warm during a short break, turn it off. Do not allow
your engine to idle longer than five minutes.
Engine Fan Switch (Option)
Your Medium Duty vehicle may have an engine fan switch
installed as an option. The switch, which is mounted on
the accessory switch panel, allows you to control the
engine fan manually or aut omatically.
• With the ignition key switch ON and the fan switch in
the ON position, the engine fan will be on regardless
of engine temperature.
• With the engine fan switch in the AUTOMATIC position, the engine fan will automatically turn on when
the engine coolant reaches a temperature of about
200°F (93°C)
WARNING! Do not work on or near the fan
with the engine running. Anyone near the
engine fan when it turns on could be killed or
seriously injured. If it is set at MANUAL, the
fan will turn on any time the ignition key
switch is turned to the ON position. In AUTO , it
could engage suddenly without warning.
Before turning on the ignition or switching
from AUTO to MANUAL, be sure no workers
are near the fan.
CAUTION: The fan or equipment near it could
be damaged if the fan turns on suddenly when
you do not expect it. Keep all tools and equipment away from the fan.
NOTE: Do not operate th e engine f an in the MANUAL position for extended per iods of time. The
fan hub was designed for intermittent operation.
Sustained operation will shorten the fan hub's
service life as well as reduce fuel economy.

Cruise Control (Option)
This feature improves fuel mileage and reduces driver
fatigue by maintaining a constant vehicle speed. The
cruise control will only operate above a programmed minimum vehicle speed, 15 mph for the CAT 3126B engine,
30 mph for the Cummins ISC engine.
Engaging the Cruise Control
NOTE: Ensure that the vehicle speed is above
the minimum cruise control speed and the
engine speed is above 1100 rpm.
1. Move the ON/OFF switch to the ON position.
NOTE: Toggling the SET/RESUME switch to the
RESUME position at this point will select the previously set cruise speed.
2. Accelerate the vehicle to the desired cruise speed.
3. Toggle the SET/RESUME switch lever to the SET
position to set the cruise speed. This to ggle switch
has additional functions that are set by the manufacturer. The two functions are:
•To decrease the cruise set speed, hold the SET/
RESUME switch in the RESUME position and coast
to a lower speed.
•To increase the cruise set speed, hold the SET/
RESUME switch in the SET position; this will accelerate the vehicle to a higher speed.
Disengaging the Cruise Control
Do one
of these steps to disengage the cruise control:
• Move the ON/OFF switch to the OFF position.
or
• Depress the brake pedal.
or
• Depress the clutch pedal.

Operating the Transmission
Introduction
Your Medium Duty vehicle is equipped with either a manual or automatic transmission with special features and
gearing to meet your particular needs. It is impor tant for
you, the driver, to understand how your particular transmission is operated. To do this, you have two sources of
information: this Operator's Manual and the transmission
manufacturer's Driver/Operator's Instruction Manual.
Because of the variety of different transmissions installed
in Medium Duty vehicles, operating procedures for your
particular transmission are not included in this manual;
therefore, you should read and understand both manuals.
Read the general guidelines and instructions that follow
and read the specific instructions contained in the transmission manufacturer's manual that is included with your
vehicle.
NOTE: You will find a shift pattern diagram in the
cab. Check to be sure you know the correct
sequence for your particular transmission.
Operating Manual Transmissions
If your truck has an automatic transmission, go to page
103
.
6, 9, 10, and 11–Speed Manual
The 6–speed synchronized manual transmission has 6
forward speeds and 1 reverse. The 9–speed transmission
has 9 forward and 2 reverse speeds, consisting of a 5–
speed low range section and a 4–speed high range section.
For specific instructions on operating one of the optional
10- or 11-speed transmissions, consult the transmission
manufacturer’s Driver/Operator Instruction Manual.

STARTING AND OPERATING THE VEHICLEOPERATING THE TRANSMISSION
Transmission Warm–Up
In cold weather [below 32°F (0°C)], you may find shifting
sluggish when you first start up. Transmission warm-up is
especially important at this time, but it is always a good
idea to warm your transmission oil before star ting o ut on
the road.
To war m the transmission lubricating oil dur ing engine
warm-up:
1. Put the transmission in Neutral.
2. Release the clutch pedal and let the transmission
operate in Neutral for three to five minutes prior to
shifting into either a forward or reverse range.
Putting the Vehicle in Motion
After making sure the vehicle's oil and air pressure are
correct and all other parts and systems are in proper
working condition:
1. If your truck is equipped with a hand throttle, disengage the hand throttle before driving the vehicle.
2. Fully depress the clutch pedal until the clutch brake
makes contact (see page 100
). The contact will occur
at about 1 inch or less from the floorboard.
• The total stroke of the clutch pedal is about 10
inches. The first 1½ inches is free travel. After the
free travel comes the release stroke, which is the
part that fully releases the clutch. The last inch
engages the clutch brake.
• Always start out in a low gear. Starting in a higher
gear, even with a light load, will cause a very jumpy
start and excessive wear.
CAUTION: Always use first gear or a low
speed range to start the vehicle in motion.
The use of a higher gear or speed range
forces undue strain on the engine, clutch,
other transmission components, and may
cause damage.
3. Evaluate the road surface conditions and terrain your
vehicle is on. Select a gear low enough to let your
vehicle start forward with the throttle at idle.
4. Push the parking brake valve handle (Yellow) against
the dash panel to release the brakes.

5. Release the clutch pedal, then gradually accelerate to
permit smooth starting,
6. Do not allow your vehicle to roll (even a little) in the
opposite direction during clutch engage ment. If you
need to start up on an incline, apply your service
brakes before you release the parking brake. Then
release your service brakes as you engage the clutch
and apply throttle.
For further instructions on operating your transmission, see
the transmission manufacturer's manual that is included with
your vehicle.
If you have a misaligned gear condition in your vehicle's
transmission and cannot start, gradually release the
clutch, allowing the drive gear teeth to line up properly.
Then the drive gear can roll enough to allow the teeth to
line up properly and complete the shift.
The best engine performance and maximum economy is
obtained if gears are proper ly selected. T his efficiency is
achieved by always selecting gears within optimum
engine rpm, which is where maximum torque and power
are obtained. For further information, see “More Driving
Tips and Techniques” on page 130.
Shifting Gears in a New Vehicle
Shift carefully in a new vehicle. The transmission may be
a little stiff at first. Avoid gear clashing by closely following
these procedures.
When you are operating a new vehicle or one that has
been exposed to cold weather, you want the transmission
lubricant (fluid) to circulate and coat the contacting surfaces of the gears. Metal conta cting metal in mo ving pa rts
may seriously damage your transmission—do not drive in
one gear for long periods of time until the transmission
lubricant has a chance to coat all contacting surfaces.
Carefully observe the free travel in the clutch for the first
few hundred miles. As the clutch lining wears and high
spots get worn smooth, you will get less free travel.
Clutch Brake and Travel (9–, 10–, and 11–Speed
Transmissions only)
These transmissions utilize a clutch brake, rather than
synchronizers. The clutch brake works by stopping all of
the gears in the transmission, allowing you to easily shift
into first gear or reverse without grinding gears. The total
