Reporting Safety Defects
If you believe that your vehicle has a defect which
could cause a crash or could cause injury or
death, you should immediately inform the National
Highway Traffic Safety Administration (NHTSA) in
addition to notifying Freightliner LLC.
If the NHTSA receives similar complaints, it may
open an investigation, and if it finds that a safety
defect exists in a group of vehicles, it may order a
recall and remedy campaign. However, NHTSA
cannot become involved in individual problems
between you, your dealer, or the vehicle
manufacturer.
To contact NHTSA, you may call the Vehicle
Safety Hotline toll-free at 1-888-327-4236 (TTY:
1-800-424-9153); go to http://www.safercar.gov; or
write to: Administrator, NHTSA, 400 Seventh
Street, SW, Washington, DC 20590. You can also

vehicle at the time of manufacture may have a higher
load capacity than that certified by the tire and rim label. If the tires and rims currently on the vehicle have a
lower load capacity than that shown on the tire and rim
label, then the tires and rims determine the load limitations on each of the axles.
Refer to Fig. 1.5 for U.S. and Canadian tire and rim

Seat Belts and Tether Belts
General Information
Seat belt assemblies are designed to secure persons in
the vehicle to help lessen the chance of injury or the
amount of injury resulting from accidents or sudden
stops. For this reason, the manufacturer urges that the
driver and all passengers, regardless of age or physical
condition, use seat belts when riding in the vehicle.
Seat belt assemblies in the vehicle meet Federal Motor
Vehicle Safety Standard 209, "Type 1," and "Type 2"
requirements. They are recommended for all persons
weighing over 50 pounds (23 kg).
A child restraint system should also be provided for
each child weighing 50 pounds (23 kg) or less. It should
meet the requirements of Federal Motor Vehicle Safety
Standard 213, "Child Restraint Systems." When providing such a restraint system, carefully read and follow all
instructions pertaining to installation and usage for the
child. Make certain the child remains in the restraint
system at all times when the vehicle is in motion.
In addition to seat belt assemblies, tether belts are installed on suspension-type seats. Tether belts help secure the seat to the floor and are intended to restrain
the seat and seat belt in case of an accident or sudden
stop.
IMPORTANT: Seat belts have a finite life which
may be much shorter than the life of the vehicle.
Regular inspections and replacement as needed
are the only assurance of adequate seat belt security over the life of the vehicle.
2.7
Seat Belt Operation
Three-Point Seat Belt with Komfort
Latch
WARNING
Wear three-point seat belts only as described below. In case of an accident or sudden stop, injuries
could result from misuse. Three-point seat belts are
designed to be worn by one person at a time.
1. Before driving the vehicle, slowly pull the link end of
the three-point seat belt out of the retractor and pull
it across your lap (from outboard to inboard) far
enough to engage the buckle. If the retractor locks
too soon, allow the belt to retract slightly, then
slowly pull it out again.
2. Fasten the three-point seat belt by pushing the link
into the buckle until it latches. See Fig. 2.8. Give
the belt a tug at the buckle. If the buckle unlatches,
repeat this step. If the problem continues, replace
the three-point seat belt.
3. Position the shoulder strap diagonally across your
chest. If desired, engage the Komfort Latch as follows:
Vehicle Access and Features
01/18/95
Fig. 2.8, Fastening the Three-Point Seat Belt (typical)
Pull on the shoulder strap to lessen the pressure of
the strap on your shoulder and chest. Allow no
more than one inch (2.5 cm) of slack between your
chest and the shoulder harness. More slack can
significantly reduce the seat belt’s effectiveness in
an accident or a sudden stop. While holding the
belt slack, press the Komfort Latch lever up, clamping the belt’s webbing. See Fig. 2.9 and Fig. 2.10.

Cab Tilting
WARNING
Never stand in front of the cab or under the cab
when the cab is being tilted. Doing so could result
in serious personal injury.
Easy access to the engine and transmission is provided
by tilting the cab. The cab can be tilted 40 degrees for
normal repair situations, or 50 degrees for removing
larger components. Torsion bars under the cab make it
easy to raise the cab by hand. A latching support arm
holds the cab in the tilted positions.

To Tilt the Cab
WARNING
Do not release the cab until the transmission has
been put into neutral, the ignition turned off, and
the parking brake set. Failure to observe these precautions could result in serious personal injury.
WARNING
Do not allow loose clothing to get near moving engine parts. To do so could result in serious personal injury.
CAUTION
Ensure the shift lever will clear the floor opening
when the cab is tilted to prevent damage to the shift
lever.
Do not raise the cab until all loose items inside the
cab are removed or fastened down and the doors
are closed. If the cab is equipped with exterior air
lines, be sure the air lines will be clear of the body
lock.
1. Apply the parking brakes and chock the tires.
2. The handle for the cab lock control is located on
the lower front face of the driver’s seat (Fig. 2.14).
Remove the handle from the housing.
3. Insert the cab lock handle in the lock control located on the passenger’s side of the rear cab panel
(Fig. 2.15). Push the safety hook knob inward, then
rotate the handle counterclockwise and pull the
handle outward. The handle will still be engaged.

Instrument and Control Panel
Figure 3.1 represents a typical dash equipped with all
of the standard and many of the optional instruments
and controls.
Warning and indicator light modules, located on each
side of the speedometer, house all of the standard and
optional warning and indicator lights. Figure 3.2 identifies the warning and indicator lights.
Controls
Ignition Switch and Key
The ignition switch can be turned to four positions: OFF,
ACCESSORY, ON, and START. See Fig. 3.3. The ignition switch key also locks and unlocks the cab doors.
The key can be inserted and removed only from the
OFF position. The headlights (low beam only), brake
lights, fog lights, dome lights, clearance lights, turn signals, hazard warning lights, parking lights, and the cigar
lighter operate with the ignition switch off, regardless of
whether the key is inserted.
In the ACCESSORY position, the wipers, heated mirrors, backup lamps, radio, ether start system, and all
electric gauges operate.
Turn the key fully clockwise to the START position, only
when starting the engine. When the engine starts, re-
lease the key. When released, the key will move to the
ON position.
In the ON position, all electrical systems are operable.
Warning lights and buzzer for low air pressure and low
oil pressure operate until the engine is started and minimum pressures are built up.
Panel Light Control
The panel lights (see Fig. 3.4) are turned on by the
headlight switch. The panel light control lever adjusts
the brightness of the instrument panel lights. Slide the
control lever up to brighten the lights, and down to dim
them. Move the control lever all the way down to turn
them off.
Headlight Switch and Daytime
Running Lights
In the up position all of the lights are off. See Fig. 3.5.
Turning the switch clockwise one position turns on the
marker/clearance lights, taillights, parking lights, license
plate light, and panel lights. Turning the switch clockwise another position turns on the headlights, marker/
clearance lights, taillights, parking lights, license plate
light, and panel lights.
