Vehicle Access and Features

Cab Door Locks and Handles

The same key that operates the ignition switch is used to lock and unlock the cab doors from the outside.
IMPORTANT: Each key is numbered. Record the number so that, if needed, a duplicate key can be made.
To unlock a door from outside the cab, insert the key in the lockset ( Fig. 2.1 ) and turn the top of the key toward the front. Pull out on the paddle handle to open the door. To lock the door, turn the top of the key toward the back; the lock cannot be operated when the door is open.

Cab Entry and Exit

WARNING
Wet or dirty shoe soles greatly increase the chance of slipping or falling. If your soles are wet or dirty, be especially careful when climbing onto, or down from, the back-of-cab area.
Always maintain three-point contact with the back-of-cab access supports while entering and exiting the back-of-cab area. Three-point contact means both feet and one hand, or both hands and one foot, on the grab handles, steps, and deck plates. Other areas are not meant to support back-of-cab access, and grabbing or stepping in the wrong place could lead to a fall, and personal injury.
Be careful not to get hands or feet tangled in hoses or other back-of-cab equipment. Carelessness could cause a person to trip and fall, with possible injury.
When entering or exiting the cab, use the grab handles and access steps as follows (refer to Fig. 2.3 ):

Seats

Due to the maximum adjustability of mid- and high-back air suspension seats, it is possible to combine the seat back recline adjustment and the seat slide adjustment so that the seat back contacts the backwall. It is the responsibility of the driver to adjust the seat to prevent damage to the seat and the cab interior.
IMPORTANT: When adjusting the seats, unless otherwise noted, make all adjustments while seated and before the engine is started.
WARNING
Keep hands, tools, and other objects away from the scissor points under the seats. Failure to do so could cause personal injury.

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, Freightliner LLC 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.

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. 2.11 . 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.
Fig. 2.11, Fastening the Three-Point Seat Belt
3.
Position the shoulder strap diagonally across your chest. If desired, engage the Komfort Latch as follows:
3.
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. 2.12 and Fig. 2.13 .
  • A. 1 Inch (2.5 cm) Maximum
Fig. 2.12, Adjusting Shoulder Harness Clearance
Fig. 2.13, Locking Komfort Latch
4.
To unbuckle the three-point seat belt, push the button on the buckle. See Fig. 2.14 . If the Komfort Latch was used, release it by giving the shoulder belt a quick tug. If you lean forward against the shoulder belt, the Komfort Latch will automatically release, and will need to be reset.
Fig. 2.14, Releasing the Three-Point Seat Belt
NOTE: The Komfort Latch does not have to be released in an emergency situation. The Komfort Latch will release by itself under rough road or other abnormal conditions. Make sure the three-point seat belt is completely retracted when it is not in use.

Lap Belt

WARNING
Wear lap belts only as described below. In case of an accident or sudden stop, injuries could result from misuse. Lap belts are designed to be worn by one person at a time.
1.
Slowly pull the link end of the lap belt across your lap. If it is necessary to lengthen the belt, tip the link end downward and pull the link until it connects with the buckle.
2.
Fasten the lap belt by pushing the link into the buckle until they latch. See Fig. 2.15 . Make sure the belt is not twisted. Check the engagement by trying to pull the link out of the buckle. If they come apart, repeat this step. If the problem continues, replace the belt.

NOTE: The belt can be shortened after it is connected by pulling on the loose end until the belt is snug, but comfortable.
3.
To release the belt, push the release button on the buckle and pull the link from the buckle.

Sleeper Compartment Bunk Restraints

General Information

On vehicles equipped with a sleeper compartment, bunk restraints should be used whenever the sleeper compartment is occupied and the vehicle is moving. Restraints are designed to lessen the chance of injury or the amount of injury resulting from accidents or sudden stops. For this reason, Freightliner LLC urges the use of bunk restraints when the sleeper compartment is occupied in a moving vehicle.
WARNING
Do not use the sleeper compartment while the vehicle is in motion unless a bunk restraint is installed and used. Not using the bunk restraint increases the chance of injury, or the degree of injury, from accidents or sudden stops to all occupants of the vehicle.

Bunk Restraint Adjustment

1.
Make sure the belt is attached to the bunk support and sleeper wall.
2.
To lengthen the belt, tip the link end downward and pull the link until it connects with the buckle.
3.
After the belt is connected, shorten it by pulling on the loose end until the belt is snug, but comfortable. Be sure the belts are not twisted. See Fig. 2.15 .

  • 1. Mattress
  • 2. Sleeper Wall
  • 3. Restraint
  • 4. Belt Anchor
  • 5. Buckle
Fig. 2.16, Bunk Restraint
1.
Starting at the foot of the bunk, pull up the link end of the belt far enough to engage the buckle.
2.
Fasten the belt by pushing the link end into the buckle until they latch. Make sure that the belt is not twisted. Check the engagement by trying to pull the link out of the buckle. If they come apart, repeat this step. If the problem continues, replace the belt. Repeat steps 1 and 2 for the other two belts located in the middle and upper portion of the bunk to lock the restraint in place.
3.
To release the bunk restraint, push the release button on the buckle at the head of the bunk and pull the link from the buckle.
3.
Repeat this step for the other two buckles to completely release the bunk restraint.

Bunk Mattress

To prevent damage to the bunk mattress and to ensure even wear, it is recommended that the mattress be turned over on a monthly basis.

Under Bunk Storage

To achieve maximum use of the under bunk storage, move the driver and passenger seats to the most forward position on the slide tracks. When you are done accessing the storage compartment, adjust the seats as necessary before operating the vehicle.

Fuse/Relay/Circuit Breaker Identification

NOTE: The fuse/relay/circuit breaker panel ( Fig. 2.17 ) is located behind an access panel below the right-hand corner (passenger's side) of the dash. To gain access to the panel, remove the two fasteners that attach the cover to the cab floor and frontwall. Depending on vehicle options, fuse/relay/circuit breaker locations may vary from those shown. Refer to Fig. 2.17 or Table 2.1 for the Fuse/Relay/Circuit Breaker Identification information.
Fig. 2.17, Fuse/Relay/Circuit Breaker Identification
NOTE: For specific fuse/relay/circuit breaker information for the Dodge Magnum V8 gasoline engine, refer to Fig. 2.18 .

Hood Tilting

A grab handle at the front of the hood provides a hand-hold for hood tilting. Stop cables prevent the hood from overtravel. In the operating position, the hood is secured to the lower cab half-fenders by a hold-down latch on each side of the hood.

Do not let the hood free-fall to the full-open position. To do so could cause damage to the hood or hood straps.

To Return the Hood

1.
Grasp the grab handle, and lift the hood to the 45-degree position.
2.
As the hood goes over center, use the bumper step and grab handle to control the rate of descent to the operating position.
3.
Make sure the hood is flush with the cowl, then secure the hood by engaging both hood hold-down latches.
IMPORTANT: Make sure that both hold-down latches are fully engaged before operating the vehicle.

Back-of-Cab Grab Handles, Steps, and Deck Plate

When climbing onto the frame rails or deck plate, use the grab handle and steps. Always maintain three-point contact with the back-of-cab access system.
A grab handle is mounted on the cab. When an optional deck plate is included, it is mounted across the top of the frame rails.
