General Information 1
Information For the Owner
If there are questions on the maintenance
and performance of your vehicle, please
discuss them with your Volvo Truck dealer.
Your authorized dealer is required to have
trained mechanics, special tools and spare
parts to fully service your vehicle. If
necessary, your dealer will contact the man-
ufacturer for any assistance.
In addition to this Operator’s Manual, there
may be additional instruction/operator’s
manuals supplied by component manufac-
turers. These manuals are placed in the
Owner’s Package and placed in the cab. Be
sure to read all the manuals thoroughly be-
fore operating the vehicle.
Also, various safety labels may be placed
on components by the component manufac-
turer. Be sure to read and follow these
labels to prevent damage to the vehicle,
personal injury or even death.
Information in this manual refers to Volvo
components and Volvo drivetrain. Informa-
tion concerning non-Volvo engines and/or
drivetrains can be obtained by contacting
the respective manufacturer.
Establish a Preventive Maintenance Pro-
gram with the help of your local Volvo
Truck dealer. A Preventive Maintenance
Program makes it possible to maximize the
amount of time your vehicle is up and run-
ning, resulting in longer component life.
This makes for a safer vehicle by reducing
any mechanical failures due to poor mainte-
nance practices.
Various truck warranty coverage plans, con-
tingent on application and weight class, are
available. Please contact an authorized
Volvo Truck Dealer for complete details.
Replacement warranty certificates for Volvo
Trucks are available from Volvo dealers.
For trucks placed in service after August 1,
2000 and operating in the USA and
Canada, Volvo dealers can print copies of
the Standard Truck Warranty Certificate
and the Premium (Purchased) Truck Cover-
age Certificate. Copies are available in
either English or Canadian French at the
dealer communication system (DCS) web-
site. Look in the Service/Warranty folder.
NOTE! Federal law requires manufacturers
to notify owners of its products in the event
of a non-compliance to a Federal Motor
Vehicle Safety Standard or if a safety re-
lated defect is discovered. If you are not
the original owner of this vehicle, please
notify us about the change in ownership at
the address below or through an authorized
Volvo Truck dealer. This is the only way
we will be able to contact you if necessary.

General Safety Information
Operating the Vehicle
Every vehicle, including heavy duty vehi-
cles, has blind spots. The size of blind
spots varies from driver to driver and from
situation to situation. As a skilled, profes-
sional driver, you are in the best position to
avoid accidents in turns, lane changes or
other maneuvers. Volvo Trucks North
America, Inc. provides standard equipment
(such as cabs, windshields, window sizes
and mirrors), preferred by most owners and
drivers under most conditions and in most
applications.
However, due to differences in the size of
drivers, their seating positions, the way that
they use and operate their vehicles, per-
sonal preferences and other factors, no
combination of mirrors and other visibility
enhancement devices will eliminate all
blind spots in every situation.
The safe operation of this vehicle is up to
you. Because of your special preferences,
needs and circumstances, you may want to
add extra mirrors and/or other visibility en-
hancement devices. If so, you should
contact an authorized Volvo Truck dealer to
obtain those parts which best fit your own
personal needs and preferences.
WARNING
All items within the cab must be secured
before the vehicle is set in motion. This
includes, but is not limited to, drinks,
clothes, books, televisions, etc. In the
event of a collision, loose items could
fly around inside the cab. This could
cause personal injury.
Never try to operate or work on this
vehicle while under the influence of al-
cohol. Your reflexes can be affected by
even a small amount of alcohol. Drink-
ing and operating this vehicle can lead
to an accident, causing serious personal
injury or death.

4 General Information
Operating In Bobtail Mode
Tractors are equipped with a bobtail air
brake proportioning valve which automati-
cally redistributes the braking force between
front and rear axles when not hooked up to
a semitrailer (bobtail operation).
When operating in bobtail mode, the rear
brake chambers receive reduced or propor-
tional brake air pressure. When the tractor
is towing a trailer, the rear brake chambers
will receive full (normal) brake pressure.
NOTE! When operating bobtail, be certain
that glad hands, trailer air hoses, electrical
cable and connectors are properly stowed
and secure. Do not allow them to rub or
chafe on other components.
WARNING
When operating bobtail, the brake
system on the vehicle reduces the possi-
bility of rear wheel brake lockup, except
on full pedal application. When bobtail-
ing, be certain that adequate pedal
pressure is applied. There is no need to
reduce pedal effort. Failure to do so may
result in increased stopping distances.

General Information 5
Do Not Overload
This vehicle has been designed and assem-
bled for a maximum gross vehicle weight
rating (GVWR) and a maximum front and
rear axle weights rating (FAWR and
RAWR). The actual rating for this vehicle
can be found on the label attached to the
door frame on the driver’s side. If any of
these three ratings is exceeded and over-
loading occurs, instability, poor handling,
failure of parts and accelerated wear can
occur.
Under no circumstances should the pub-
lished GVWR, FAWR, and/or RAWR be
exceeded. Failure to observe these pre-
cautions can lead to the loss of vehicle
control, resulting in a crash causing seri-
ous personal injury or death.
Do not exceed the load rating of the
tires or the vehicle weight ratings. Over-
loading may result in tire failure causing
loss of vehicle control, leading to an ac-
cident resulting in severe personal injury
or death.
W0001210
Operating
Before driving this vehicle, locate the in-
struments and controls, and become
thoroughly familiar with their operation.
After starting and when driving, always
check to make sure that the instrument
readings are normal.

Modifications to Vehicle
Chassis Frame
Frame side rails are heat treated. No weld-
ing is permitted because structural failure
may result. Do not drill through either top
or bottom flanges. A warning label is also
attached to the frame for information.
Drilling is permitted in the frame web in
accordance with a specified hole spacing
pattern. Consult a Volvo Truck dealer to
obtain approved hole spacing dimensions or
refer to the Frame Rail and Cross Member
Service Manual.

Do not weld on any part of the frame or
drill holes in the top or bottom flanges.
Serious structural damage could occur.
Frame Alterations
Under no circumstances can the frame be
cut and an extension piece added to in-
crease the wheelbase. The only alteration
allowed is wheel base shortening, where
the only change in the frame rail is a new
hole pattern drilled for the new location of
the rear suspension.
Welding In Vehicle
Do not weld anywhere in or on the vehicle
before disconnecting batteries, all electronic
control units (ECU) and instrument cluster.
See page 249 for more information. Do not

8 General Information
Exhaust and Noise Emissions
General
USA
The Federal Clean Air Act, Section 203 (a)
(3), states the following concerning the re-
moval of air pollution control devices or
modification of a certified engine to a non-
certified configuration:
“The following acts and the causing thereof
are prohibited:
(3) For any person to remove or render in-
operative any device or element of design
installed on or in a motor vehicle or motor
vehicle engine in compliance with regula-
tions under this part prior to its sale and
delivery to the ultimate purchaser, or for
any manufacturer or dealer knowingly to
remove or render inoperative any such de-
sign after sale and delivery to the ultimate
purchaser.”
Specifically, please note that no person may
make such changes prior to the sale and
delivery of the vehicle to the ultimate pur-
chaser, and, in addition, no manufacturer or
dealer may take such action after sale and
delivery of the vehicle to the ultimate pur-
chaser. The law provides a penalty of up to
$10, 000 for each violation.
Canada
The same conditions that apply in the USA
apply to Canada, with one exception. After
the vehicle is sold to a retail customer, that
is, the end user, the jurisdiction controlling
the emission control devices becomes the
province in which the vehicle is licensed.
No changes should be made that render any
or all of the devices inoperative.
Should the owner/operator wish to make
any changes to the emission control de-
vices, check with the provincial authority
before making any such changes.
Mexico
The same conditions that apply in the USA
apply to Mexico. Refer to the Mexican
Federal Law for Emission Control which
adheres to EPA regulations. No changes
should be made that render any or all of
the emissions control devices inoperative.
Should the owner/operator wish to make
any changes to the emission control de-
vices, check with the state authority before
making any such changes.
