Be sure the latch that holds the upper bunk in the folded position is working properly so the bunk will not fall down. Pull on the bunk to be sure it is latched securely. If the bunk falls, you could be injured. Failure to comply may result in death, personal injury, equipment or property damage.

Per FMCSR 392.60 - Unauthorized Persons Not to be Transported. Federal law prohibits the transportation of persons in commercial vehicles unless they are specically authorized in writing by the motor carrier. See the cited FMCSR for a complete description of the regulation and exemptions.

WARNING!

Any loose items on the upper or lower bunk should be moved to a secured place before driving the vehicle. Fail ure to comply may result in death, personal injury, equipment or property damage.

Upper Rear Sleeper Storage

Your vehicle may be equipped with an upper storage shelf that extends over the lower bunk and across the rear

of the sleeper. The following warning applies:

WARNING!

Overhead compartments are not intended for items exceeding their designed weight limits. Exceeding the weight limits may cause the shelf to collapse and or items may fall out in a sudden stop which may lead to death or personal injury.

Compartments in the cab and sleeper are provided for storage of necessary items used during operation. The storage areas above the door are designed to hold a combined total not exceeding 14 lbs (6 kg) per compartment and the other overhead compartments (including those in

1-30

Y53-1200-1B1 (04/13)

the optional sleeper) should hold a Safety Restraint Tips combined total not exceeding 5 lbs (2.2 kg) per compartment.

• Do not wear a belt over rigid or

breakable objects in or on your clothing, such as eye glasses, pens, keys, etc., as these may cause injury in an accident.

• Any authorized person sleeping

in your vehicle while it is moving should use the bunk restraint.

• Any authorized person sitting in

the sleeper area on the sofa bed (if equipped) while it is moving should wear a seat belt.

• A responsible operator sees to it

that everyone in the vehicle rides or sleeps safely. The operator is responsible to inform any passengers or co-drivers how to properly use the seat belts and bunk restraint in the vehicle.

• Do not strap in more than one

person with each belt.

• Keep seat belt and bunk restraint

buckles free of any obstruction that may prevent secure locking.

• Damaged or worn belts in the cab

or sleeper, subjected to excessive stretch forces from normal wear, must be replaced. They may not protect you if you have an accident.

• Any belts or restraints that have

been subjected to an accident should be inspected for any loose (attaching) hardware or damaged buckles.

• If belts show damage to any part

of assembly, such as webbing, bindings, buckles or retractors, they must be replaced.

• Do not allow safety belts (seat

or bunk) to become damaged by getting caught in door, bunk or seat hardware, or rubbing against sharp objects.

(04/13) Y53-1200-1B1 1-31

• All belts must be kept clean or the

retractors may not work properly.

• Never bleach or dye seat or bunk

restraint belts: chemicals can weaken them. Do, however, keep them clean by following the care label on the belts. Let them dry completely before allowing them to retract or be stowed away.

• Make sure the seat belts and

bunk restraint of the unoccupied passenger seat or bunk is fully wound up on its retractor or is stowed, so that the belt or restraint tongue is in its properly stowed position. This reduces the possibility of the tongue becoming a striking object in case of a sudden stop.

• Do not modify or disassemble the

seat belts or bunk restraint in your vehicle. They will not be available

to keep you and your passengers safe.

• If any seat belt or bunk restraint

is not working properly, see an authorized dealer for repair or replacement.

START-UP

Introduction

The following section covers start-up procedures for getting your vehicle ready for the road.

Safe Vehicle Operation

For your safety, as well as those around you, be a responsible driver:

• If you drink alcohol, do not drive.

• Do not drive if you are tired, ill, or

under emotional stress.

Safe driving is only possible with the proper concentration on the driving task. Keep distraction to a minimum to improve your concentration. Examples of distractions may include radio controls, GPS navigation controls, cellular telephone calls, cellular text messages, reading or reaching for something on the oor. Minimizing your distractions will improve safe driving and will help avoid an accident involving death or personal injury.

Be aware of local regulations that may prohibit the use of cellular telephones while driving. In addition to being an unsafe practice, it may be against local

or federal ordinances to use cellular devices while operating the vehicle.

Much has gone into the manufacturing of your vehicle including advanced engineering techniques, rigid quality control, and demanding inspections. These manufacturing processes will be enhanced by you, the safe driver, who observes the following:

• Knows and understands how to

operate the vehicle and all its controls.

• Maintains the vehicle properly.

• Uses driving skills wisely.

For more information, refer to Department of Transportation Regulation 392.7, which states that interstate commercial motor vehicles are not to be driven unless the driver is sure that certain parts and accessories are in working order.

(04/13) Y53-1200-1B1 1-33

The use of alcohol, drugs, and certain medications will seriously impair perception, reactions, and driving abil ity. These circumstances can substantially increase the risk of an accident. Failure to comply may result in death, personal injury, equipment or property damage.

WARNING!

Do not text and drive. Your reaction time, perceptions and judgment can be affected while texting or using any

other form of mobile messaging while driving. Failure to comply may result in death, personal injury, equipment or property damage.

Vehicle Loading

Compare your vehicle's load capacity with the total load you are carrying. If adjustments need to be made, make them, do not drive an overloaded vehicle. If you are overloaded or your load has shifted, your vehicle may be unsafe to drive.

WARNING!

Do not exceed the specied load rating. Overloading can result in loss of vehicle control, either by causing com ponent failures or by affecting vehicle handling. Exceeding load ratings can also shorten the service life of the ve hicle. Failure to comply may result in death or personal injury.

The gross vehicle weight rating (GVWR), or the maximum front and rear gross axle weight ratings (GAWRs) are determined by the components installed from the factory

1-34

(04/13)Y53-1200-1B1

on to the vehicle and their designed specications. (Axle weight ratings are listed on the driver's door edge.)

The following are some denitions of weight you should know:

GVWR: is the Gross Vehicle Weight Rating. This is the MAXIMUM WEIGHT your vehicle is allowed to carry, including the weight of the empty vehicle, loading platform, occupants, fuel, and any load. Never exceed the GVWR of your vehicle.

GCW: is the actual combined weight, or Gross Combination Weight (GCW), of your vehicle and its load: vehicle, plus trailer(s), plus cargo.

GAWR: is the Gross Axle Weight Rating. This is the total weight that one axle is designed to transmit to the ground. You will nd this number listed on the driver's door edge.

Load Distribution: be sure any load you carry is distributed so that no axle has to support more than its GAWR.

WARNING!

An unevenly distributed load or a load too heavy over one axle can affect the braking and handling of your vehi cle, which could result in an accident. Even if your load is under the legal limits, be sure it is distributed evenly. Failure to comply may result in death, personal injury, equipment or property damage.

(04/13) Y53-1200-1B1 1-35

Emergency Equipment

It is good practice to carry an emergency equipment kit in your vehicle. One day, if you have a roadside emergency, you will be glad the following items are with you:

• window scraper

• snow brush

• container or bag of sand or salt

• emergency light

• warning triangles

• small shovel

• rst aid kit

• re extinguisher

• vehicle recovery hitches (see

Vehicle Recovery Guidelines on page 2-12 for details).

Driver's Check List

To keep your vehicle in top shape and maintain a high level of safety for you, your passengers, and your load, make a thorough inspection every day before you drive. You will save maintenance time later, and the safety checks could help prevent a serious accident. Please remember, too, that Federal Motor Carrier Safety Regulation 392.7 requires a pre-trip inspection and so do commercial trucking companies.

You are not expected to become a professional mechanic. The purpose of your inspections is to nd anything that might interfere with the safe and efcient transportation of yourself, any passengers, and your load. If you do nd something wrong and cannot x it yourself, have an authorized dealer or qualied mechanic repair your vehicle right away.

The following operations are to be performed by the driver. Performing these checks and following the maintenance procedures in this manual will help keep your vehicle running properly.

1-36

Y53-1200-1B1 (04/13)

Low Air Alarm Turns On

1. Slow down carefully.

2. Move a safe distance off the road and stop.

3. Place the transmission in neutral (park with automatic transmissions, if equipped) and set the parking brake. (Refer to Parking Brake Valve on page 4-23 and Operating the Transmission on page 4-19, for transmission shifting and parking brake information.)

4. Turn OFF the engine.

5. Turn ON the emergency asher and use other warning devices to alert other motorists.

(04/13) Y53-1200-1B1 2-3

WARNING!

If the air pressure falls below 60 psi (414 kPa) the spring brakes may stop the vehicle abruptly, which could

cause an accident resulting in death or personal injury. Observe the red warning lamps on the gauges. If one comes on, do not continue to drive the vehicle until it has been properly repaired or serviced.

If the light and alarm do not turn off at startup, do not try to drive the vehicle until the problem is found and xed. (Refer to Using the Brake System on page 4-21, for more brake information.)

Stop Engine Lamp Turns On

Stop Engine Lamp - If the

Stop Engine warning lamp illuminates, it means you have a serious engine system problem.

WARNING!

This should be considered an emergency. You should stop the vehicle as safely as possible and turn OFF the ignition. The vehicle must be serviced and the problem corrected before driv ing again. Failure to do so may cause severe engine or DPF damage, or cause an accident which may result in death or personal injury.

Engine Oil Pressure Lamp Turns On

Engine Oil Pressure Lamp

- If the oil pressure suddenly drops, or the audible alarm and engine oil pressure warning light come on while driving, do the following:

1. Slow down carefully.

2. Move a safe distance off the road and stop.

3. Place the transmission in park

and set the parking brake. (See Parking Brake Valve on page 4-23 and Operating the Transmission on page 4-19, for transmission shifting and parking brake information.)

4. Turn OFF the engine.

5. Turn ON the emergency asher and use other warning devices to alert other motorists.

2-4

Y53-1200-1B1 (04/13)

6. Wait a few minutes to allow oil to drain into the engine oil pan, and then check the oil level. (See Oil Level Check on page 5-94, for details on checking oil level.)

7. Add oil if necessary. If the problem persists, contact an authorized dealer as soon as possible.

CAUTION

Continuing to operate your vehicle with insufcient oil pressure may cause severe engine damage or cause an accident which may result in equipment or property damage.

It is important to maintain oil pressure within acceptable limits. If oil pressure drops below the minimum psi (kPa) a Red Warning Lamp on the oil pressure gauge will illuminate and the Stop Engine Lamp will come ON.

Engine is Overheating

The cooling system may overheat if the coolant level is below normal or if there is sudden loss of coolant, such as a split hose. The system may also temporarily overheat during severe operating conditions such as:

• Climbing a long hill on a hot day

• Stopping after high-speed driving

If either one of the above occurs, DO

NOT TURN OFF THE ENGINE unless: a) the Low Water warning device

indicates a loss of coolant, b) the Red Warning lamp (on the gauge) and Check Engine lamp comes ON, c) the Buzzer sounds showing an overheat condition, or d) if you have any other reason to suspect the engine may be overheating - follow these steps.

1. Reduce engine speed and stop. When stopped, place the transmission in Neutral and set the

parking brake. (See Parking Brake Valve on page 4-23 and Putting the Vehicle in Motion on page 4-16, for transmission shifting and parking brake information.) Keep the engine running.

2. Check to ensure the Oil Pressure Gauge reads normal. (See Engine Oil Pressure Gauge on page 3-11, for further information.)

3. Make sure the engine fan is turning by switching the Engine Fan Switch from AUTO to MAN (Manual).

4. Increase the engine speed to about one-half of full operating speed, or 1,100 to 1,200 rpm, maximum.

5. Return the engine speed to normal idle after 2 or 3 minutes.

6. Monitor the engine temperature. After the temperature returns to normal, allow the engine to idle

(04/13) Y53-1200-1B1 2-5

3 to 5 minutes before shutting it off. This allows the engine to cool gradually and uniformly.

7. If overheating came from

severe operating conditions, the temperature should have cooled by this time. If it has not, stop the engine and let it cool before checking to see if the coolant is low.

For further information on engine temperature and operating engines properly, see the Engine Operation and Maintenance Manual and Starting and Operating the Vehicle on page 4-5. Check the coolant level after each trip when the engine has cooled. The coolant level should be visible within the surge tank—add coolant if necessary. See Topping Off in Engine Cooling System on page 5-72, for instructions on checking and lling the coolant expansion tank.

WARNING!

To reduce the chance of death, personal injury and/or vehicle damage from overheated engines, which can result in a re, never leave the engine idling without an alert driver present. If the engine should overheat, as indi cated by the engine coolant temperature light, immediate action is required to correct the condition. Continued unattended operation of the engine, even for a short time, may result in serious engine damage or a re.

WARNING!

Do not remove the radiator ll cap while the engine is hot. Scalding steam and uid under pressure may escape. You could be badly burned. Failure to comply may result in death or personal injury.

Fuse or Relay Blows

Fuses are located behind the drivers side kick panel, below the ignition switch, and accessible by a door panel. See Power Distribution Box on page 5-84.

The vehicle main power relays are located in the engine compartment. See Power Distribution Center (PDC) on page 5-81.

WARNING!

Do not replace a fuse with a fuse of a higher rating. Doing so may damage the electrical system and cause a re. Failure to comply may result in death, personal injury, equipment or property damage.

2-6 Y53-1200-1B1 (04/13)

CAUTION

Before replacing a fuse, turn OFF all lights and accessories and remove the ignition key to avoid damaging the electrical system.

CAUTION

Never patch fuses with tin foil or wire. This may cause serious damage else where in the electrical circuit, and it may cause a re.

CAUTION

If a circuit keeps blowing fuses, have the electrical system inspected for a short circuit or overload by an autho rized dealer as soon as possible. Failure to do so could cause serious damage to the electrical system and/or vehicle.

Fuse Inspection and Replacement

All the electrical circuits have fuses to protect them from a short circuit or overload. If something electrical on your chassis stops working, the rst thing you should check for is a blown fuse.

1. Turn OFF all lights and accessories

and remove the ignition key to avoid damaging the electrical system.

2. Determine from the chart on the fuse panel which fuse controls that component.

3. Remove that fuse and see if it is blown.

1 Blown

If it is blown, replace it with a fuse of the same rating.

If a fuse of the same rating is not available, a fuse of a lower rating may be temporarily substituted. You can also use a fuse from a circuit you can do temporarily without (for example an accessory circuit or radio).

CAUTION

When replacing a failed circuit breaker, always use an approved cir cuit breaker with a current rating equal to or less than the circuit breaker be ing replaced. Only use the approved Type II modied reset circuit breakers. NEVER use a Type I (automatic re set) or Type III (manual reset) circuit breaker. A fuse with a current rating equal to or less than the circuit breaker being replaced can also be used.

(04/13) Y53-1200-1B1 2-7

JUMP STARTING VEHICLES

Introduction

Jump starting a vehicle is not a recommended practice due to the various battery installations and electrical options.

However, if your battery is discharged (dead), you may be able to start it by using energy from a good battery in another vehicle. This is termed jump starting. Be sure to follow the precautions and instructions below.

WARNING!

Batteries contain acid that can burn and gasses that can explode. Ignoring safety procedures may result in death, personal injury, equipment or property damage.

WARNING!

Never jump start a battery near re, ames, or electrical sparks. Batteries generate explosive gases that could explode. Keep sparks, ame, and lighted cigarettes away from batteries. Failure to comply may result in death, personal injury, equipment or property damage.

WARNING!

Never remove or tamper with battery caps. Ignoring this could allow battery acid to contact eyes, skin, fabrics, or painted surfaces. Failure to comply may result in death, personal injury, equipment or property damage.

Be careful that metal tools (or any metal in contact with the positive terminal) do not contact the positive battery terminal and any other metal on the vehicle at the same time. Remove

metal jewelry and avoid leaning over the battery.

2-8

Y53-1200-1B1 (04/13)

To Jump Start your Vehicle

WARNING!

When jump starting using a battery booster, it is best to jump start with an equivalently powered vehicle. Ver ify that the booster battery has the same volt and CCA specications as the dead battery before attempting to jump start. Failure to comply may cause an explosion resulting in death, personal injury, equipment or property damage.

CAUTION

Applying a higher voltage booster battery may cause expensive damage to sensitive electronic components, such as relays, Electronic Control units or electronics in general. Failure to com ply may result in equipment damage.

CAUTION

Improper hook-up of jumper cables or not following these procedures can damage the alternator or cause seri

ous damage to both vehicles.

WARNING!

Heed all warnings and instructions of the jumper cable manufacturer. Fail ure to comply may result in death, personal injury, equipment or property damage.

Preparing the vehicles:

1. Remove any personal jewelry that may come in contact with the

battery terminals.

2. Select a jumper cable that is long enough to attach to both vehicles in a way that ensures neither vehicle touches each other.

3. Position the two vehicles together, but do not allow them to touch.

4. Turn OFF all lights, heater, radio, and any other accessory on both vehicles.

5. Set the parking brakes: pull out the Yellow button located on the dash.

6. Shift the transmission into park position or neutral for manual transmissions. (See Operating the Transmission on page 4-19 and Parking Brake Valve on page 4-23, for transmission shifting and parking brake information.)

(04/13) Y53-1200-1B1 2-9

7. If either vehicle is equipped with battery disconnects ensure they are in the "OFF" position prior to connecting the two vehicles.

Connect the batteries:

1. Attach one end of a jumper cable to the positive (+) terminal of the discharged (dead) battery. This will have a large red + or P on the battery case, post, or clamp.

2. Attach the other end of the same cable to the positive (+) terminal of the good (booster) battery.

3. Attach the remaining jumper cable

FIRST to the negative (-) terminal (black or N) of the good battery.

4. Attach the other end of the negative cable to a bare metal part not bolted to the engine block.

NOTE

Always connect positive (+) to positive (+) and negative (-) to negative (-).

5. If either vehicle is equipped with battery disconnects, ensure that they are in the "ON" position.

6. Start the vehicle that has the good battery rst. Let it run for 5 minutes.

7. Start the vehicle that has the discharged (dead) battery.

If the engine fails to start, do not continue to crank the starter but contact the nearest authorized dealer.

2-10 Y53-1200-1B1 (04/13)

Remove jumper cables:

WARNING!

When disconnecting jumper cables, make sure they do not get caught in any moving parts in the engine com partment. Failure to comply may result in death, personal injury, equipment or property damage.

Reverse the above procedure exactly when removing the jumper cables. With engine running, disconnect jumper cables from both vehicles in the exact reverse order, making sure to rst remove the negative cable from the vehicle with the discharged battery.

(04/13) Y53-1200-1B1 2-11

VEHICLE RECOVERY AND SPRING BRAKES

Vehicle Recovery Guidelines

Your vehicle is equipped with removable Recovery Hitches, designed for short distance recovery purposes only. Use only the provided hitches, according the following instructions. When using this connection, do not transport your vehicle over long distances. (If your vehicle does not have the proper hitches, contact your dealer.)

All lubricating and clutch application oil pressure is provided by an engine-driven pump, which will not work when the engine is stopped. You could seriously damage your vehicle by towing it with the driveline connected and the drive wheels on the ground. Worse, when vehicles are towed, either by wrecker or piggyback,

the lubricant in the top front of the drive axle will drain to the rear. This will leave the top components dry. The resulting friction may damage them. Always remove the main drive axle shafts before towing your vehicle.

CAUTION

Remove the drive axle shafts or lift the driving wheels off the ground before towing the vehicle. Towing the vehicle with either the wheels on the ground or the axle shafts in the axles will cause damage to the axle gears.

CAUTION

If your vehicle has a Meritor axle with a driver-controlled main differential lock, install the caging bolt before removing the axles for towing, see Driver Con trolled Main Differential Lock on page 2-16. Installing the caging bolt pre vents damage by locking internal axle components in position.

CAUTION

Connect only to the Recovery Hitches, see Vehicle Recovery Guidelines on page 2-12. Connections to other struc tural parts could damage the vehicle. Do not attach to bumpers or brackets. Use only equipment designed for this purpose. Failure to comply may result in equipment damage.

2-12 Y53-1200-1B1 (04/13)

1 Recovery Hitch Sockets

Recovery Procedure

1. Review and understand all the cautions and warnings of this section, see Vehicle Recovery Guidelines on page 2-12.

2. Install the recovery hitches, see Recovery Hitch Installation on page 2-15.

3. Disconnect the drive axle shafts and cover the open hubs. This is necessary because if the transmission is driven by the driveshaft (rear wheels on the ground), no lubricant will reach the gears and bearings, causing damage to the transmission.

4. Install the recovery rigging using a safety chain system, see Recovery Rigging on page 2-19.

5. Make sure the recovered vehicle's parking brakes are released.

6. If you desire to use the recovered vehicle’s brakes, ensure that

the vehicle’s air system is connected to that of the recovery vehicle. Ensure that any air line that has been removed from a driver-controlled main differential lock is rmly capped to prevent loss of air pressure from the recovery vehicle if it is supplying air pressure. If you don’t desire to use the recovered vehicle’s brakes, ensure that you cage the spring brakes before attempting to move the vehicle, see Driver Controlled Main Differential Lock on page 2-16.

WARNING!

Before towing a vehicle, test your air brakes to ensure that you have prop erly connected and inspected the recovery vehicle’s brake system. Failure to do so could lead to a loss of vehicle control which may result in an accident involving death or personal injury.

Recovery Hitch Connection

Specially designed hitches are required to recover your vehicle. The recovery hitches attach to the frame, see Recovery Hitch Assembly on page 2-15.

Two hitch assemblies, made up of the following parts, are recommended for the proper recovery of your vehicle: see Recovery Hitch Assembly on page 2-15.

WARNING!

Do not use parts from other trucks or materials from other sources to repair a hitch or to replace a missing hitch. The parts provided for recovery are made of high strength steel specically designed for vehicle recovery. Fail ure to use the correct factory equipment may result in an accident involving death or personal injury.

2-14 Y53-1200-1B1 (04/13)

Driver Controlled Main Differential

Follow these steps to lock a driver-controlled main differential.

An open air line on the recovered vehicle will cause a leak in the air system of the recovery vehicle if both vehicles’ brake systems are connected. This could cause a loss of system air, which can cause the service brakes not to function, resulting in the sudden application of the spring brakes caus ing wheel lock-up, loss of control, or overtake by following vehicles. You could be in an accident involving death or personal injury. Ensure that any air line that has been removed from a driver-controlled main differential lock is rmly capped to prevent loss of air pressure from the recovery vehicle if it is supplying air pressure.

WARNING!

1. Lift driving wheels off the ground or remove the driveline and axle shafts before towing the vehicle.

CAUTION

Failure to lift the driving wheels off the ground or remove the driveline and axle shafts before towing the vehicle could seriously damage your vehicle. All lubricating and clutch application oil pressure is provided by an engine-driven pump, which does not work when the engine is stopped. When vehicles are towed either by wrecker or piggyback, lubricant in the top front of the drive axle will drain to the rear. This will leave the top components dry, resulting in friction that will seriously damage these components.

2. Cover open hubs when removing drive axle shafts.

2-16 Y53-1200-1B1 (04/13)

CAUTION

Water, dirt and other material can enter an open hub or axle. This can contaminate the axle uid and cause possible damage to components. Ensure that the hubs are covered with plas tic whenever a drive axle shaft is removed.

3. For vehicles with driver-controlled main differential lock, install the caging bolt before removing the axle shafts for towing.

a. Remove the air line and rmly

cap.

b. Remove the caging bolt from

its storage hole.

c. Screw the caging bolt into

the air line hole. When fully engaged, a 0.25 - 0.5 in. (6.35-12.7 mm) space will remain between the air cylinder and the bolt head.

This action will lock the differential by pushing a piston into a “lock” position.

CAUTION

Failure to install the caging bolt when

towing vehicles with driver-control main differential lock can result in damage by failing to lock internal com ponents in position.

WARNING!

Ensure there are no open air lines on the recovered vehicle if the recovery vehicle and recovered vehicle brake systems are connected. An open air line on the recovered vehicle will cause a leak in the air brake system of the recovery vehicle possibly causing death, personal injury, equipment or property damage.

CAUTION

A recovered vehicle will have no operational brake system. Additionally, the rear axle spring brakes will probably be applied.

• If you desire to use the recovered

vehicle’s brakes, ensure that the vehicles air system is connected to that of the recovery vehicle. Also ensure that any air line that has been removed from a driver-controlled main differential lock is rmly capped to prevent loss of air pressure from the recovery vehicle.

• If you don’t desire to use the recovered vehicle’s brakes, ensure that you cage the spring brakes before attempting to move the vehicle.

4. Install recovery hitches and rigging.

(04/13) Y53-1200-1B1 2-17

CAUTION

Connect recovery rigging only to hitches intended for that purpose. Do not attach to bumpers or brackets.

Connections to other structural parts could damage the vehicle.

Recovery Hitch Capacities

The maximum rated loads for vehicle recovery varies depending on the direction or angle of pull. These capacities are listed in the table below and are for the two hitches working together, simultaneously.

Hitch Capacities

DIRECTION OF

PULL

Directly Forward 80,000 Directly Vertical or Horizontally to the Side 45º in any Direction * Both hitches pulled simultaneously.

MAXIMUM CAPACITY

(Lb) *

14,600

20,000

CAUTION

Recovery pull maximums assume the tow rigging evenly distributes the load between both recovery hitches. See examples in Recovery Rigging on page 2-19 for details. Serious damage to the vehicle may occur if rigging is not connected properly.

CAUTION

When recovering ditched or bogged vehicles, stay well below Maximum Capacities. Even at loads below maxi mum, the physical strain of recovering a vehicle could damage axles, sus pensions, fth wheels, etc.

2-18 Y53-1200-1B1 (04/13)

Recovery Rigging

To connect to the vehicle, follow the suggested rigging methods below.

• Use a double chain or cable setup

that distributes the load equally to both hitches. See 1 or 2 in Recovery Rigging illustration.

• Never loop a single chain or cable

through both hitches (3).

• Use a spreader or equalizer bar to

distribute the load on both hitches (1).

• If no spreader bar is available,

connect the main tow chain or

cable no closer than 6 ft. from the vehicle (2).

1. Spreader Bar or Equalizer Preferred

(04/13) Y53-1200-1B1 2-19

2. Minimum 6 FT. Acceptable

3. NEVER USE SINGLE CHAIN OR CABLE LOOPED THROUGH TOW DEVICES

Returning Vehicle to Service

You will have to add lubricant to prevent damage after your vehicle has been towed.

1. Into the pinion cage, add 1 pint (.47 liter) of lubricant or into the interaxle differential, add 2 pints (.94 liter) of approved lubricant.

2. After adding the specied type and amount of lubricant, drive the vehicle. It should be unloaded. Drive 1 to 2 miles (1.5 to 3 km) at a speed lower than 25 mph (40 km/h). This will thoroughly circulate the lubricant through the assembly.

Spring Brakes—Manual Release

Recovering a vehicle requires that you release the parking brakes. There may be times when there is not enough air pressure to release the parking brakes. In such cases, the parking brakes (or Spring Brakes) can be manually released.

WARNING!

Do not drive vehicle with malfunctioning brakes. If one of the brake circuits should become inoperative, braking distances will increase sub stantially and handling characteristics while braking will be affected. You could lose control of your vehicle or cause an accident. Have it towed to the nearest dealer or qualied repair facility for repair. Failure to comply may result in death, personal injury, equipment or property damage.

The brakes can be released in this manner should the pressure in the air system not be enough to release them. This may occur in instances where the engine's air compressor is not able to get the system up to operating pressure.

WARNING!

Do not disassemble a spring brake chamber. These chambers contain a powerful spring that is compressed. Sudden release of this spring may re sult in death or personal injury.

WARNING!

Do not operate a vehicle when the spring brakes have been manually released. Driving a vehicle after its spring brakes are manually released is extremely dangerous. The brakes may not function. Failure to comply may result in death, personal injury, equipment or property damage.

2-20 Y53-1200-1B1 (04/13)

WARNING!

Always secure the vehicle with wheel chocks, chains, or other safe means to prevent rolling before manually releas ing the spring brakes. Releasing the spring brakes on an unsecured vehicle could lead to an accident. The vehicle could roll, which may result in death, personal injury, equipment or property damage.

To move a vehicle immobilized by the spring brakes due to loss of air pressure in the brake system, perform the following procedure:

1. Remove the cap from the spring chamber.

2. Remove the release stud assembly from the side pocket, and remove the release nut and washer from the release

stud.

3. Slide out the release stud.

4. Insert the release stud through the opening in the spring chamber where the cap was removed. Insert it into the pressure plate. Turn the release stud 1/4 turn clockwise in the pressure plate. This secures the cross pin into the cross pin area of the pressure plate and locks it into the manual release position.

5. Assemble the release stud washer and nut on the release stud.

6. With a wrench, turn the release stud assembly nut until the compression spring is 90-95 percent caged. While doing this, check to make sure the push rod (adapter push rod or service push rod) is retracting. Do not over-torque the release stud assembly. (S-Cam type maximum: 50 lb-ft, Wedge type maximum: 30 lb-ft). The spring brake is now mechanically released.

(04/13) Y53-1200-1B1 2-21

Sand, Mud, Snow and Ice

If the vehicle gets stuck in sand, mud, snow, or ice:

• Move the gearshift lever or

selector from First to Reverse.

• Apply light pressure on the

accelerator pedal while the transmission is in gear.

• Remove your foot from the

accelerator while shifting.

• Do not race the engine.

• For best traction and safety, avoid

spinning the wheels.

WARNING!

Do not spin the wheels faster than 35 mph (55 km/h). Spinning a tire at speedometer readings faster than 35 mph (55 km/h) can be dangerous. Tires can explode from spinning too fast. Under some conditions, a tire may be spinning at a speed twice that shown on the speedometer. Any resulting tire explosion could cause death or personal injury to a bystander or passenger, as well as extensive vehicle damage: including tire, trans mission and/or rear axle malfunction.

Comply with the following instructions to avoid transmission damage:

• Always start vehicle in motion with

the shift lever in rst gear.

• Be sure that transmission is fully

engaged in gear before releasing the clutch pedal (manual only).

• Do not shift into reverse while the

vehicle is moving.

• If the vehicle needs to be

recovered from being stuck, do not permit the vehicle to be towed for long distances without removing the driveshaft.

Tire Chains

If you need tire chains, install them on both sides of the driving axle.

Chains on the tires of only one tandem axle can damage the driveline U-joints and the interaxle differential. Repairs could be costly and time-consuming. Failure to comply may result in equip ment damage.

CAUTION

2-22 Y53-1200-1B1 (04/13)

Towing the Vehicle

Towing the vehicle should be done by either an authorized dealer or a commercial vehicle towing service. The dealer or commercial towing service will have the necessary equipment to safely tow the vehicle and should be able to make arrangements to limit any damage to the vehicle. The towing service and the dealer should be aware of towing regulations and safety precautions.

The towing service will ensure that the following precautions are taken:

• Use of a safety chain system.

• Abide by all local towing

regulations.

• Ensure that the towing device

does not contact any surfaces that could be damaged while in transit.

• If towing from the front, ensure

that the rear axles are prepared for towing.

• If towing from the rear, ensure

that all body components such as roof, side and chassis fairings are secured properly to avoid damage while in transit.

WARNING!

Secure the roof, side and chassis fairings while towing from the rear. An unsecured fairing may come off of the vehicle during transit. Failure to secure the fairings while towing may cause an injury accident resulting in death or personal injury.

Check Messages

1. Speedometer

2. Fuel Level, Primary

Check messages are provided to give the operator additional information regarding systems that require attention due to a system malfunction and/or operating conditions that may hinder safe and proper performance for the vehicle. Some messages can be managed by the operator while others may require an authorized dealer repair.

The Speedometer indicates the vehicle speed in miles per hour (mph) and in kilometers per hour (km/h). The Speedometer cluster also includes several warning and indicator lamps (see Audible Alerts on page 3-29).

The Primary Fuel gauge indicates the total (approximate) amount of fuel in the fuel tank. In addition to indicating empty and full, the gauge(s) also indicate the fuel level in graduated increments. When the fuel level for the tank is below 1/4 full, a red warning light in the gauge will come on.

Primary

Secondary

(04/13) Y53-1200-1B1 3-9

NOTE

For Export vehicles, the fuel gauges will not state: ULTRA LOW SULFUR DIESEL FUEL ONLY.

NOTE

This vehicle may be manufactured

with different fuel systems and differ ent draw tube locations. Because of this and the amount of road crown, it is recommended that you do not operate your vehicle with less than one-quarter of your truck’s fuel capac ity. Allowing the fuel level to go below one-quarter of capacity could result in the lack of fuel to keep the engine running. In addition, you will want to keep the fuel tanks at least half-full to reduce condensation of moisture in the tanks. This moisture can damage the engine.

WARNING!

Do not carry fuel containers or any container used to store combustible liquids. Failure to comply may result in death, personal injury, equipment or property damage.

Do not remove a fuel tank cap near an open ame. Fuel vapors may be hot and combustible and can cause an explosion or re. Failure to comply

may result in death, personal injury, equipment or property damage.

Refer to Refueling on page 4-60 for more information.

WARNING!

3. Tachometer

The Tachometer measures the engine speed in revolutions per minute (RPM).

The RPM Detail is also available as a viewable screen in the Driver Performance Center. Viewing the RPM detail is accomplished by using the MCS dial to rotate to the [VIRTUAL GAUGES].

The tachometer is a useful gauge when attempting to drive efciently. It will let you match driving speed and gear selection to the operating range of your engine. If the engine speed gets too high, you can select a higher gear to lower the RPM's. If the engine speed drops too low, you can select a lower gear to raise the RPM's. (Refer to Driving Tips and Techniques on page 4-52 for further instructions on driving techniques and using the tachometer.) To avoid engine damage, do not let the pointer exceed maximum

3-10

Y53-1200-1B1 (04/13)

governed speed. (See your Engine

Operation and Maintenance Manual

for RPM recommendations.)

5. Engine, Coolant Temperature

6. Engine, Oil Pressure

The tachometer will illuminate a small green light just below the numbers of the gauge. This is to indicate the engine speed for optimal fuel economy. See Optimal Engine Speed on page 4-54 for more information on how to use this indicator during normal operation.

(04/13) Y53-1200-1B1 3-11

The water temperature gauge shows the temperature of the engine coolant. Under normal operating conditions the water temperature gauge should register between 165° and 205°F (74° and 90°C). Under certain conditions, somewhat higher temperatures may be acceptable. But the maximum allowable temperature is 210°F (99°C), except for certain special engines. Check your engine manual to be sure.

Please refer to Engine is Overheating on page 2-5 for instructions on what to do if the engine is overheating.

It is important to maintain oil pressure within acceptable limits. If oil pressure drops below the minimum psi a red warning light in the gauge will turn on, the Stop Engine light will come on and an audible alarm tone will sound.

For further information on engine oil and normal operating pressures, see the Engine Operation and Maintenance Manual.

CAUTION

Operating your vehicle with insufcient oil pressure will cause serious engine damage.

If the oil pressure fails to rise within 10 seconds after the engine starts, stop the engine and determine the cause.

Check the engine manufacturer's manual for the correct oil pressure ranges for your vehicle's engine.

If the oil pressure suddenly drops, or the audible alarm and engine oil pressure warning light come on while driving, please refer to Engine Oil Pressure Lamp Turns On on page 2-4

regarding what to do if oil pressure is insufcient.

8. Driver Performance Center

The display can show multiple warning lights. Warning information will appear momentarily and then will minimize in the screen. Reviewing the warnings can be done by navigating the menu via the Menu Control Switch.

10. Primary and Secondary Air Pressure

Primary Air Pressure

Secondary Air Pressure

For further information on engine gauges and operating your engine properly, refer to Engine Maintenance on page 5-93.

3-12

The air gauge indicates the air pressure in the brake system. There are two dial indicators, the primary indicator and icon is for the rear brake system while the secondary dial and icon is for the front brake system. The gauge indicates the amount of air pressure in each system in pounds per square inch (psi).

On vehicles equipped with metric air pressure gauges, the gauge face plate includes a kPa (major) scale and psi (minor) scale.

Y53-1200-1B1 (04/13)

Please refer to Low Air Alarm Turns On on page 2-3 for instructions on what to do if the air system becomes inoperative.

NOTE

Be sure the air pressure registers more than 100 psi (690 kPa) in both service systems before you move the vehicle.

NOTE

If the pressure in either or both circuits falls below 65 psi (448 kPa), a red warning light in the gauge will turn on and an audible alarm tone will sound when the engine is running.

WARNING!

If the air pressure falls below 60 psi (414 kPa), the spring brakes may stop the vehicle abruptly which could cause an accident resulting in death or per sonal injury. Observe the red warning lamps on the gauges. If one comes on, do not continue to drive the vehicle un til it has been properly repaired or serviced. If the light and alarm do not turn off at start-up, do not try to drive the vehicle until the problem is found and xed.

WARNING!

The air pressure warning light and the audible alarm tone indicate a danger ous situation: there is not enough air pressure in the air tanks for repeated

braking and the brake system has failed. Without the use of your service brakes your spring brakes could sud

denly apply causing a wheel lock-up, loss of control, or over-take by fol lowing vehicles. This may cause an accident resulting in death or personal injury. Bring the vehicle to a safe stop right away, while you still have control of the vehicle.

(04/13) Y53-1200-1B1 3-13

11. Diesel Exhaust Fluid (DEF)

The diesel exhaust uid gauge shows the approximate amount of DEF uid in the DEF tank. Besides empty and

full, the gauge also indicates 1/4, 1/2, and 3/4 of total capacity. DEF uid is required to meet certain emission requirements. Do not allow your DEF tank to remain empty. Please refer to your Engine Aftertreatment Controls Operator's Manual for more details about DEF uid.

CAUTION

Failure to do so can result in the driver not being attentive to the vehicle’s road position or situation, which could lead to an accident and possible death, personal injury or equipment damage.

The Driver Performance Center, located at the top of the instrument cluster, displays important vehicle information through a constant monitoring of systems when any of the following conditions are met:

• ignition key in ON or ACC positions

• ignition timer is active

• MCS button is pushed or spun

(independent of ignition key switch position)

• clock alarm sounds

• driver or passenger door is opened

• hazard warning lamp switch is on

• Service brake switch is on

• Tractor marker lamp switch is on

• Trailer marker lamp switch is on

• Low Voltage Display not active

• and the screen has not been put

into "Display Off Mode"

In addition to a blank screen, the following are menu items and the information available within each menu selections.

NOTE

Some Driver Performance Center functions are only accessible when the vehicle is parked. Other functions are accessible while the vehicle is mov ing or when parked. Each function is identied in the following descriptions:

(04/13) Y53-1200-1B1 3-15

1. Odometer/Trip Odometer

The Odometer/Trip Meter comes on when the door is opened and when the ignition key is in the ACC or ON position.

The odometer displays the distance your vehicle has traveled. The display

can be congured to display Metric units or English units.

The current trip odometer displays how far the vehicle has gone on a particular trip and can display in increments of a tenth of a unit.

Please refer to Trip Information on page 3-24 for more information.

2. Outside Air Temperature

Used to display outside air temperature information and a warning of low temperatures.

The display will also alert the driver when the outside temperate approaches freezing (32° F or 0° C) by displaying a snowake symbol. The symbol will turn on when the temperature drops below 34° F or 11° C and ash for the rst 3 seconds, then stay on until the temperature goes above 37° F or 28° C.

The systems unit of measure (Fahrenheit or Celsius) can be changed by navigating to the settings menu.

The outside air temperature display will come on when the door is open and when the ignition key is in the ACC or ON position and turn off when the ignition switch is turned off.

The outside air temperature display uses a sensor (located at the bottom of the driver's side mirror assembly) to measure outside air temperature only.

Navigation of the system is organized into 3 levels of functions. The rst level of organization is identied as "Trunk" level functions. The second level is identied as "Branch" level functions. The lowest level of functions are identied as the "Leaf" level functions. Some screens will appear differently depending if the vehicle is moving or parked. The following images provide an example of a screen to get familiarized with the interface.

Trunk Level

At this level, you can navigate between functions by turning the MCS knob. You can enter a function by pushing the knob; at which you would then be going to what is termed the “branch” level of the software.

Display of a trunk level option

Branch Level

In the branch level of functions, the MCS knob rotation controls a cursor highlight. When something is highlighted, an MCS Push will select that item or toggle its contents. Toggle elds typically use a darker colored text to distinguish them from elds that take the user to the “Leaf level”.

Description of Menu Screens

Blank Screen

This screen is available in both parked and driving modes.

The blank screen mode is to allow for minimized screen content, while still maintaining some of the more permanent screen elements such as the odometer, outside air temperature, warning cue, etc. This is different from the Display OFF Mode where the entire display shuts off.

The blank screen mode is selected through the rotary MCS knob. The Display OFF Mode is selected by pressing the button above the MCS knob for more than 2 seconds.

(04/13) Y53-1200-1B1 3-23

The virtual gauges function is selected through the rotary MCS knob and is available in both parked and driving modes.

Virtual gauges provide dynamic information about the vehicle's performance. Spin the MCS button to scroll through the available gauges and push to select the desired gauge to view.

Ignition Timer

This function allows the driver to set a timer to shut off the truck. This feature is only available when the vehicle is parked. After the timer is set, the ignition key may be turned to the off position and removed. The engine will continue to run for the programmed time, then will shut off automatically.

Fuel Economy

This function displays the dynamic fuel economy performance of the vehicle. It shows Average Speed, Average Fuel Economy, and a dynamic instantaneous indication of fuel economy above or below the current average. The screen is available when driving. Average fuel economy is computed by the fuel consumed during the trip (see the next section for Trip information). The fuel economy for a trip will be reset when that trip odometer is reset.

Trip Information

This function allows you to keep trip information data on up to 4 separate trips – labeled A, B, C, and D. Trips are also selectable as “Active” or “Inactive” so you can use the data logging function to treat trips separate from each other, or as segments of a combined trip. When driving, the screen only allows you to toggle which trip is viewed in the trip odometer and set the active/inactive status. When parked you can select and view a variety of data collected for each trip, as seen in the list below:

3-24

4. ABS Information a. ABS Make b. ABS Model c. ABS Software Version #

The display has a message alerting function that overrides the normal viewing and navigation of functions when an issue occurs on the truck. These alert messages are called “pop-ups” because they take over the screen. Some messages are low enough priority that they can be “suppressed”, which is done by pushing the MCS button. There will be a screen indicator showing which messages are suppressible. If multiple pop-ups are present at the same time, they are viewed in a stack format, and

By selecting “Review Warnings” the pop-up messages are recalled, and if multiple are active, the stack can be navigated by spinning the MCS knob. The warning description can be viewed when driving or when parked, but

3-26 Y53-1200-1B1 (04/13)

the fault details are visible only when parked. The menu selection shown in the image above simply won’t be there if the truck is driving, though the warnings and tell-tale indicators on the cluster will still be available as indicators if the problem is serious. Fault details screens include:

1. how many faults, shown in a scrollable stack format

2. which ECU the fault is being generated from

3. a text description of the issue

4. it’s actual fault code

5. action instructions telling you what to do (e.g. seek service soon vs. correct at next scheduled service visit)

An example of a Fault Details screen is shown below:

Fault Details Example

Settings

This function is available only when the vehicle is parked.

Various settings may be changed using this function. The operator can change the time format (12hr/24hr), the time of day, alarm settings, units of measure for the display (mile/kilometer), and the language being displayed. Changing settings functions are typically done one of two ways. Items can be toggled straight from the highlighted selection (at the branch level); these cases use dark blue text that changes to the set value. Others are menu selections that bring up new “leaf level” screens. The following shows examples of turning the alarm on/off vs. screens that are navigated to in order to set the clock time.

WARNING SYMBOLS

Guide to the Warning Symbols

The warning lights and audible alarm may indicate a system malfunction. Check the lights frequently, and respond properly as soon as you see one go on. These lights could save you from a serious accident.

When multiple warning icons are shown on the instrument cluster, they will appear at rst and then minimize. When minimized they will be represented in the active warnings area of the display (see Driver Performance Center on page 3-14 for details). A triangle represents a warning registered and a diamond represents a check message.

WARNING!

Do not ignore a warning light or audible alarm. These signals tell you some thing is wrong with your vehicle. It could be a failure in an important sys tem, such as the brakes, which could lead to an accident causing death or injury. Have the appropriate system checked immediately.

Check messages are provided to give the operator additional information regarding systems that require attention due to a system malfunction and/or operating conditions that may hinder safe and proper performance for the vehicle. The system will emit a chime to alert the operator that a message is appearing on the cluster. Some messages can be managed by the operator while others may require an authorized dealer repair.

The following is a list of Warning Light/Indicator Symbols that appear

in the instrument cluster and Driver Performance Center.

• the Symbol Name

• the appearance of the Symbol

• the Symbol Color when it is

illuminated

• whether the symbol is standard

(Std) or optional (Opt)
