Driver’s Manual
Foreword
This manual provides information needed to operate and understand the vehicle and its components. More detailed information is contained in the Owner’s Warranty Information for North America booklet, and in the vehicle’s workshop and maintenance manuals.
Custom-built Freightliner vehicles are equipped with various chassis and cab components. Not all of the information contained in this manual applies to every vehicle. For details about components in your ve­hicle, refer to the chassis specification pages in­cluded in all new vehicles and to the vehicle specifi­cation decal, located inside the vehicle.
For your reference, keep this manual in the vehicle at all times.
IMPORTANT: Descriptions and specifications in this manual were in effect at the time of printing. Freightliner Trucks reserves the right to discon­tinue models and to change specifications or design at any time without notice and without incurring obligation. Descriptions and specifica­tions contained in this publication provide no warranty, expressed or implied, and are subject to revisions and editions without notice.
Environmental Concerns and Recommendations
Whenever you see instructions in this manual to dis­card materials, you should first attempt to reclaim and recycle them. To preserve our environment, fol­low appropriate environmental rules and regulations when disposing of materials.
Event Data Recorder
This vehicle is equipped with one or more devices that record specific vehicle data. The type and amount of data recorded varies depending on how the vehicle is equipped (such as the brand of engine, if an air bag is installed, or if the vehicle features a collision avoidance system, etc.).
This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record data in certain crash or near-crash situations, such as air bag deployment or hitting a road obstacle, that will assist in understanding how a vehicle’s systems
performed. The EDR is designed to record data re­lated to vehicle dynamics and safety systems for ap­proximately 60 seconds. This data can help provide a better understanding of the circumstances in which crashes and injuries occur. Data recorded includes the following items:
how various systems in the vehicle were oper­ating
engine system information
how far (if at all) the driver was depressing the accelerator
if the driver was depressing the brake pedal
how fast the vehicle was traveling
NOTE: Data is not recorded by the EDR under normal driving conditions. Personal data such as name, gender, age, and crash location are not recorded. However, other parties such as law enforcement could combine the EDR data with the type of personally identifying data rou­tinely acquired during a crash investigation.
To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties that have the special equipment, such as law enforcement, can read the information if they have access to the vehicle or the EDR.
Emissions and Fuel Efficiency Compliance
This vehicle must be regularly inspected and main­tained as indicated in the 122SD and Coronado 132
Maintenance Manual, and in the Pre- and Post-Trip Inspections and Maintenance chapter in this manual,
in order to continue satisfactory performance and ensure coverage of the vehicle under the manufac­turer’s warranty. Many maintenance procedures en­sure that the vehicle and engine continue to comply with applicable emissions standards. Maintenance procedures, using components engineered to comply with greenhouse gas emissions and fuel efficiency regulations, may be performed by an authorized Daimler Trucks North America dealer, an indepen­dent outlet, or the vehicle owner or operator.
The vehicle owner is responsible for determining the suitability of replacement components to maintain

Federal Motor Vehicle Safety Standard Labels
NOTE: Due to the variety of Federal Motor Ve­hicle Safety Standard (FMVSS) certification re­quirements, not all of the labels shown will apply to your vehicle.
Tractors with or without fifth wheels purchased in the U.S. are marked as certified by means of an FMVSS certification label. See to the driver-side B-pillar, as shown in
Fig. 1.3. This label is attached
Fig. 1.4.
The tire and rim portion of the FMVSS certification label certifies suitable tire and rim combinations that can be installed on the vehicle, for the given gross axle weight rating. Tires and rims installed on the 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.
Trucks built without a cargo body that are intended for service in the U.S. have an incomplete vehicle certification label attached by the final-stage manu­facturer. See the incomplete vehicle document included with the vehicle, and certifies that the vehicle conforms to all applicable FMVSS regulations in effect on the date of completion.

Electrical System
Vehicle Power Supply
WARNING
Do not attempt to modify, add, splice, or remove electrical wiring on this vehicle. Doing so could damage the electrical system and result in a fire that could cause serious personal injury or prop­erty damage.
Power Distribution
There are four power distribution modules in the ve­hicle: the main power distribution module (PDM), the auxiliary PDM, the powertrain PDM, and the power­net distribution box (PNDB).
The main PDM contains the circuit breakers and fuses required to protect the vehicle. It is located in the top of the right-hand dash, and is accessed by removing the four fasteners in the top of the dash panel.
The auxiliary PDM is located on the B-pillar access door, behind the driver’s seat. It controls power to the HVAC system, the sleeper, and anti-lock braking.
The powertrain PDM is mounted off the driver’s-side frontwall in the engine compartment. It controls power to the engine, aftertreatment system, transmis­sion, and other powertrain-related circuits.
The PNDB is mounted on the cab frontwall near the steering column. It supplies power to the powertrain PDM, the main PDM and other cab functions, includ­ing the clock.
Load Disconnect Switch
WARNING
Turning the load disconnect switch to the OFF position does not disconnect the connection be­tween the battery and the starter. To work on the vehicle safely, the negative leads must be discon­nected from the battery.
The load disconnect switch is used to avoid exces­sive draw on the battery when the vehicle is parked for an extended period of time. See the load disconnect switch is set to OFF, it signals the PNDB to disconnect battery power to powertrain and accessory loads. The power to the
Fig. 3.1. When
05/13/2009 f545527
Fig. 3.1, Load Disconnect Switch
aftertreatment-system control module is disconnected after the DEF purge function is completed.
The load disconnect switch is mounted in one of two locations:
inside the cab on the left side of the driver’s seat (left-hand-drive vehicle);
on the battery box
IMPORTANT: The ignition should be turned OFF before turning the load disconnect switch to ON or OFF.
Low Voltage Disconnect, Optional
The optional Sure Power Low Voltage Disconnect (LVD) system monitors battery power when accesso­ries are being used while the engine is shut down. The system automatically turns off cab and sleeper accessories when voltage drops to 12.3 volts, to en­sure that there is enough battery power to start the vehicle. An alarm sounds for one minute before ac­cessories are turned off. If no action is taken within that minute, the LVD module will shut off power to predetermined cab and sleeper circuits. These cir­cuits will remain off until the LVD measures 13.0 volts applied to the system, which can be achieved by starting the engine. After the engine is started, the system will reset.
Vehicles are equipped with an LVD label on the drivers-side sun visor, indicating the presence of the system.

Instrumentation Control Units
The instrument control unit (ICU) provides the driver with engine and vehicle information. It is comprised of standard and optional gauges, an audible warning, a driver message center, and a lightbar containing warning and indicator lamps (also known as tell­tales). Warning and indicator lamps illuminate in red (danger), amber (caution), green (status advisory), or blue (high-beam headlights active).
122SD and Coronado vehicles are equipped with an ICU4, ICU4M, or ICU4Me. See Fig. 4.1, Fig. 4.2, and
Fig. 4.3 for typical ICU layouts.
The following headings in this chapter provide addi­tional information and operating instructions for ICU components:
"Warning and Indicator Lights"
"Standard Instruments"
"Optional Instruments"
"Driver Message Center"
Ignition Sequence
When the ignition is turned on, the ICU runs a self­check. Observing the ignition sequence is a good way to ensure the ICU is functioning properly.
IMPORTANT: Do not crank the engine until the ICU self-check is complete.
NOTE: Air gauges do not complete a sweep of their dials during the ignition sequence.
When the ignition is turned on, the following actions should occur:
electronic gauges complete a full sweep of their dials
warning and indicator lamps illuminate, then are extinguished
audible alert sounds for approximately four seconds or until sufficient air pressure builds up in the primary and secondary air systems
DEF level indicator illuminates all segments green, then turns them off one at a time before turning the leftmost segment amber and then red
Freightliner logo displays on the ICU4Me driver message center for two seconds.
software revision level of the ICU is displayed under the Freightliner logo on the driver mes­sage center, followed by any active faults
NOTE: If active faults are present, take the ve­hicle to an authorized Freightliner service facility as soon as possible.
If the ICU receives active fault codes, it displays them one after the other until the parking brake is released or the ignition is turned off. Once the park­ing brake is completely released, the ICU displays the odometer. If there are no active faults, the ICU displays the odometer after the self-check completes.
When the self-check is complete on an ICU4M, the fasten seat belt screen displays if the engine is off. If the engine is running, the idle hours screen displays.
Audible Alerts
An audible alert sounds during the ignition sequence and whenever one of the following conditions exists:
Engine oil pressure falls below the minimum preset value.
Coolant temperature rises above the maximum preset value.
Air pressure falls below approximately 70 psi (483 kPa).
Parking brake is set with the vehicle moving faster than two miles per hour.
System voltage falls below 12 volts.
Door is open with the parking brake off.
Headlights are on with the door open and the ignition off.
Occupied seat belts are not fastened and the parking brake is not set (optional).
Outside temperature falls below 35°F (1.7°C) (optional).
Warning and Indicator Lights
The ICU lightbar has three to four rows of warning and indicator lights with icon symbols (also known as telltales). The positions of the lights may vary for the different ICUs, but the symbols are standard for all applications. See and commonly used warning and indicator lamps.

cation or to a service facility.
IMPORTANT: Safely bring the vehicle to a stop
When the red STOP engine lamp illuminates, most engines are programmed to shut down au­tomatically within 30 seconds. The driver must immediately move the vehicle to a safe location at the side of the road to prevent causing a haz­ardous situation that could cause bodily injury, property damage, or severe damage to the en­gine.
Fig. 4.4 for an explanation of the aftertreatment
See system (ATS) warning indicators, and actions re­quired to avoid further engine protection steps.
The STOP engine lamp illuminates when the engine protection system is activated in one of two ways. On some engines, the engine protection system will der-
on the side of the road and shut down the en­gine as soon as the red light is seen. If the en­gine shuts down while the vehicle is in a haz­ardous location, turn the key to the OFF position for a few seconds, then restart the engine and move the vehicle to a safer location.
On other engines, the engine protection system will shut down the engine. It will first derate the engine, then shut it down completely 30 to 60 seconds after the indicator illuminates (depending on the critical fault type) if the condition does not improve. Bring the vehicle to a stop on the side of the road before the engine shuts down.

Primary and Secondary Air Pressure Gauges
WARNING
If air pressure falls below minimum pressure, the braking ability of the vehicle will be limited. Slow the vehicle down and bring it to a gradual stop. Do not attempt to move the vehicle until air pres­sure has risen above the minimum level. Moving a vehicle without adequate braking power could cause an accident resulting in property damage, personal injury, or death.
Air pressure gauges register the pressure in the pri­mary and secondary air systems. Normal pressure with the engine running is 100 to 120 psi (689 to 827 kPa) in both systems.
A low air pressure warning lamp and audible warn­ing, connected to both the primary and secondary systems, activate when air pressure in either system drops below a minimum pressure of 64 to 76 psi (441 to 524 kPa).
When the engine is started, the warning light and buzzer remain on until air pressure in both systems exceeds minimum pressure.

Instruments
Speedometer
Two speedometer face options are available. The U.S. version of the speedometer registers speed in both miles per hour (mph) and kilometers per hour (km/h), with mph in larger numbers.
The metric version of the speedometer face reverses this arrangement, with km/h in larger numbers.
Tachometer
The tachometer indicates engine speed in revolutions per minute (rpm) and serves as a guide for shifting the transmission and keeping the engine in the ap­propriate rpm range. For low idle and rated rpm, see the engine identification plate.
Voltmeter
The voltmeter indicates the vehicle charging system voltage when the engine is running and the battery voltage when the engine is stopped. By monitoring the voltmeter, the driver can stay aware of potential battery charging problems and have them fixed be­fore the batteries discharge enough to create starting difficulties.
The voltmeter will normally show approximately 13.7 to 14.1 volts when the engine is running. The voltage of a fully charged battery is 12.7 to 12.8 volts when the engine is stopped. A completely discharged bat­tery will produce only about 12.0 volts. The voltmeter will indicate lower voltage as the vehicle is being started or when electrical devices in the vehicle are being used.
If the voltmeter shows an undercharged or over­charged condition for an extended period, have the charging system and batteries checked at a repair facility.
On a vehicle equipped with a battery isolator system, the voltmeter measures the average voltage of all the batteries when the engine is running. When the en­gine is stopped, the voltmeter shows only the gel cell battery voltage and does not indicate the voltage of the engine-starting batteries.
the battery becomes fully discharged. If an exter­nal charger is needed, disconnect the gel cell battery and use only an external battery charger that has been approved for gel cell batteries.
Optional Instruments
Optional instruments are not found on every vehicle. They are listed here in alphabetical order, to make the information easier to find.
Air Restriction Gauge
The air intake restriction gauge measures the vacuum on the engine side of the air cleaner. On standard installations, it is mounted on the air intake duct in the engine compartment. As an option for easier viewing, an air intake restriction gauge may be located in the ICU.
NOTE: Rain or snow can wet the air filter, caus­ing a temporarily higher than normal reading.
Air intake restriction vacuum is measured in inches of water (inH graduated indicator (see gauge on the dash, check the gauge with the engine off. If the air restriction value equals or exceeds the value shown in needs to be replaced.

Brake Application Air Pressure Gauge
The application air pressure gauge registers the air pressure being used to apply the brakes, and should be used for reference only. The gauge will not regis­ter until the foot pedal is depressed or the hand brake lever is applied.
Drive Axle Oil Temperature Gauges
NOTICE
A sudden increase in oil temperature that is not caused by a load increase may indicate mechani­cal failure. Bring the vehicle to a safe stop and investigate the cause to prevent further damage. Do not operate the vehicle until the cause has been determined and corrected.
During normal operation, drive axle oil temperature gauges should read as follows:
160 to 220°F (71 to 104°C) for Detroit™and Meritor
180 to 200°F (82 to 93°C) for Dana Spicer® drive axles
Under heavy loads, such as when climbing steep grades, temperatures that exceed the normal oil tem­perature range for a short period are not unusual. If the temperature returns to normal when the load de­creases, there is no problem.
