In an Emergency

Hazard Warning Lights

The hazard warning light switch tab is located on the turn signal control lever. See Fig. 13.1 .To operate the hazard lights, pull the tab out. All of the turn signal lights and both of the indicator lights on the control panel will flash.

Fig. 13.1, Hazard Warning Light Switch Tab (left-hand drive shown)

To cancel the hazard warning lights, push the turn signal control lever either up or down, then return the lever to its neutral position.

Fire Extinguisher

A fire extinguisher is located in the cab by the driver's door.

Emergency Kit, Optional

An optional emergency kit package is located between the seats, at the front of the center console, if the vehicle does not have a sleeper compartment. If there is a sleeper compartment, the emergency kit is located elsewhere, depending on vehicle configuration. The package includes one or more of each of the following: first aid kit, a reflective vest, and a triangular reflector and flare kit.

If there is an emergency while driving, cautiously pull off the road, paying attention to other traffic. Turn on the hazard warning lights. Place the flares and reflector along the side of the road, to alert other drivers that an emergency situation exists.

Use extreme care when placing flares in emergency situations that involve exposure to flammable substances such as fuel. An explosion or fire could occur causing serious personal injury.

Towing

NOTE: The vehicle shown in the figures is for reference only and may not match the model of your vehicle.

Shutdown the engine and set the parking brake.

Open the hood. Remove the tow hooks, located behind the driver's-side bumper. See Fig. 13.2 . Close and latch the hood.

NOTICE

New or ungreased tow hooks may be hard to install. Tow hooks that are not properly installed may be damaged or break.

Install the tow hooks onto the tow hook receivers through the tow hook holes in the bumper, rotating the hooks so the hook opening faces down. See Fig. 13.3 . Pull the tow hooks to ensure they are securely engaged in the tow hook receivers.

Lower the stinger assembly so that it is level and approximately 1 inch (0.3 cm) off the ground. Back the tow truck so that the crossbar with lift adaptors is within 6 inches (15 cm) of the Aero bumper. See Fig. 13.4 .

NOTICE

When using tow hooks to move the vehicle, do not pass a sling (for example, a rope or chain) from one hook to another. Known as reeving, this practice is not permissible in most industrial applications of towing and hoisting. Reeving can overload the hooks and result in damage to the vehicle. See Fig. 13.5 .

Pull the tow cables out of the tow truck and connect the tow cable lifting hooks onto the tow hooks, then extend the recovery boom within 4 to 6 inches (10 to 15 cm) of being vertical of the tow hooks. See Fig. 13.6 .

IMPORTANT: Do not reeve when towing.

2. Chain

Lift the front of the vehicle until there is enough clearance for the stinger and crossbar to pass under the bumper. See Fig. 13.7 .

If enough clearance can not be gained with a single lift, jack stands or other means capable of supporting the weight on the front axle must be used while the cables are shortened to allow a second lift.

Failure to chock the tires or connect the tow truck's air brake system before releasing the spring parking brakes could allow the disabled vehicle to suddenly roll. This could cause property damage or personal injury.

Chock the rear tires.

NOTICE

Reference the applicable axle manufacturer's information to avoid damaging the axle when towing the truck.

Use mid-rise or high-rise forks, or lift adaptors (part number 0200020) on the crossbar to provide clearance for the aerodynamic bumper. See Fig. 13.8 and Fig. 13.9 .

Extend the stinger and place the lift adaptors under the axle. Make certain the lift adaptors are under the front suspension springs between the U-bolts. See Fig. 13.10 and Fig. 13.11 .

10.

Secure the axle to the crossbar with a chain or ratchet strap.

NOTICE

Failure to remove the driveline(s) or the drive axle shafts when towing the vehicle with the rear wheels on the ground could result in damage to the transmission and other parts.

11.

Remove all drivelines or all axle shafts for towing.

12.

Remove the tow cables from the tow hooks and retract the recovery boom. See Fig. 13.12 .

13.

Remove the tow hooks from the bumper.

14.

Connect the air and electrical supply lines from the tow truck to the vehicle being towed.

IMPORTANT: On vehicles equipped with a front air suspension, either air pressure must be supplied to the secondary air system or the front suspension must be blocked to operating height with wooden spacers and the axle chained to the frame to prevent damage to the vehicle.

15.

Release the park brake and remove the chocks from the rear tires.

16.

Use the stinger to pull the vehicle close to the back of the tow truck for final towing position. See Fig. 13.13 .

Connect the safety chains. See Fig. 13.14 .

Emergency Starting with Jumper Cables

When using jumper cables, follow the instructions below.

Batteries release explosive gas. Do not smoke when working around batteries. Put out all flames and remove all sources of sparks or intense heat in the vicinity of the battery. Do not allow the vehicles to touch each other. Do not lean over the batteries when making connections, and keep all other persons away from the batteries. Failure to follow these precautions could lead to severe personal injury as a result of an explosion or acid burns.

NOTE: On vehicles equipped with an optional jump-start post, attach the positive cable clamp to that post instead of to the battery.

Apply the parking brakes and turn off the lights and all other electrical loads.

Connect an end of one jumper cable to the positive terminal of the booster battery (or jump-start post, if equipped), and connect the other end of the cable to the positive terminal of the discharged battery (or jump-start post, if equipped). See Fig. 13.15 .

A. To Ground
B. Connect 3rd
C. To Frame (ground)
D. Connect Last
E. To Starter
F. Connect 2nd
G. Connect 1st

1. Booster Battery
2. Discharged Battery

Fig. 13.15, Jumper Connections

Do the next step exactly as instructed and do not allow the clamps of one cable to touch the clamps of the other cable. Otherwise, a spark could occur near a battery, possibly resulting in severe personal injury from explosion or acid burns.

Connect one end of the second jumper cable to the negative terminal of the booster battery, and connect the other end of the cable to a ground at least 12 inches (300 mm) away from the batteries of the vehicle needing the start. The vehicle frame is usually a good ground. Do not connect the cable to or near the discharged batteries.

Start the engine of the vehicle with the booster batteries, and let the engine run a few minutes to charge the batteries of the other vehicle.

Attempt to start the engine of the vehicle with the batteries receiving the charge. Do not operate the starter longer than 30 seconds, and wait at least two minutes between starting attempts to allow the starter to cool.

When the engine starts, let it idle a few minutes.

Disconnect the grounded cable from the frame or other non-battery location, then disconnect the other end of the cable.

Disconnect the remaining cable from the newly charged battery (or jump-start post, if equipped) first, then disconnect the other end.

Fire in the Cab

The incidence of fire in heavy and medium-duty trucks is rare, according to data from the National Highway Traffic Safety Administration. Federal Motor Vehicle Safety Standard #302 limits the flammability of specified materials used inside the cab but, despite this, most materials can burn.

Do not allow flames, sparks, or any other heat sources (such as cigarettes or light bulbs) to contact materials in the cab. Any materials in the cab in contact with such heat sources could cause serious personal injury as well as damage to the vehicle.

In Case of a Cab Fire

As quickly as possible, bring the vehicle to a safe stop, apply the parking brake, turn off the ignition, and get out of the vehicle.
