In an Emergency

Hazard Warning Lights

The hazard warning light switch is located on the dash in what is referred to as the master module. See Fig. 24.1 . The hazard lights can be activated regardless of the ignition switch position.

To activate the hazard lights, push the center of the switch once. The switch will blink at the same rate that the hazard lights flash. Push the switch again to turn them off. All the turn signal lights on the vehicle and trailer, as well as the turn signal indicators in the ICU, flash simultaneously when the hazard lights are activated.

Fire Extinguisher

A fire extinguisher is located either in the cab by the driver's door, or in the baggage compartment.

Emergency Kit, Optional

An optional emergency kit is located in the cab. The kit includes one or more of the following: a first aid kit, a reflective vest, a triangular reflector, a flare kit, and (on vehicles with a Davco fuel/water separator) a spin-on fuel filter element.

If there is an emergency while driving, cautiously pull off the road. 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.

Emergency Filter Replacement, Davco

If the filter cover on the Davco fuel/water separator is broken, it will not be possible to operate the vehicle. A standard spin-on filter will correct this problem.

Refer to the Davco web site (www.davcotec.com) for additional information.

To replace the filter on all Davco fuel/water separators, follow this procedure:

Shut down the engine, apply the parking brake, and chock the tires.

Put a clean receptacle under the fuel/water separator and attach a piece of hose to the drain valve, to direct fuel into the receptacle.

NOTE: The drain valve on the Fuel Pro 382 has a 1/2-inch (12.7-mm) opening; use a hose with a 1/2-inch pipe thread to fit correctly. Open the drain valve by turning it one-quarter revolution.

Drain the fuel until it is below the level of the collar. See Fig. 24.2 for the model 382 fuel/water separator.

Remove the vent and seal.

NOTE: The vent and seal are not needed in the emergency replacement. They should be retained for later installation at the time when the cover is replaced.

Using a DAVCO collar wrench, remove the collar. See Fig. 24.3 . Do not use pliers or channel-lock pliers.

Fig. 24.3, DAVCO Collar Wrench

Remove the cover, cover seal, and spring. Retain them for later assembly.

Remove the filter element and dispose of it properly.

NOTE: Remove the rubber grommet from the stud.

Install the standard engine spin-on filter (included in the emergency kit) on the threaded stud.

Install the cover, cover seal, and spring, as removed.

10.

Install the collar over the cover. Simultaneously apply downward pressure to the top of the clear cover until it is seated on the body of the lower housing and hand tighten the collar until it no longer spins freely. Using the collar wrench, tighten the cover 18 lbf·ft (24 N·m). This is equivalent to rotating the collar clockwise two or three additional ribs, depending on the specific filter model.

11.

Start the engine and run it at increased rpm for one minute to purge air from the fuel lines.

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.

Make sure both electrical systems are the same voltage. Electronic devices on both vehicles can be damaged when connected to a vehicle with a different operating voltage.

NOTE: On vehicles equipped with optional underhood jump start posts, connect to these posts instead of the batteries.

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

Remove the battery box cover by pulling on the end of each hold-down latch until the end clears the catch, then pivoting the latches out of the way, and lifting off the cover. See Fig. 24.4 .

Always connect the battery, jumper cables, and charger correctly (positive-to-positive and negative-to-negative). Connecting a charging device backwards (positive-to-negative) can severely damage the vehicle electrical content and cause non-warrantable failures.

Connect the positive (+) jumper cable to the positive battery post on the Cascadia needing the jump start, then connect the other end of the positive jumper cable to the positive battery or jump start post of the vehicle providing the jump. See Fig. 24.5 .

A. – Battery Cable to Vehicle
B. + Battery Cable to Vehicle
C. + Jumper Cable (connect first and disconnect last)
D. – Jumper Cable (connect last and disconnect first)

Fig. 24.5, 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 to the negative battery post of the Cascadia needing the jump start.

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.

10.

Install the cover; be sure it is positioned properly before fastening the latches.

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. 24.6 . 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. 24.7 . Pull the tow hooks to ensure they are securely engaged in the tow hook receivers.

Fig. 24.6, Tow Hooks

Fig. 24.7, Tow Hooks Installed, Facing Down

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. 24.8 .

Fig. 24.8, Positioning the Stinger Assembly

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. 24.9 .

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. 24.10 .

IMPORTANT: Do not reeve when towing.

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. 24.12 and Fig. 24.13 .

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. 24.16 .

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. 24.17 .

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.
