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

Manual and Maintenance

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

, and in the Pre- and Post-Trip Inspections

chapter in this manual, in order to

Electrical System

Electrical Power Distribution

Electrical power distribution provides battery power to the electrical and electronic systems. See power distribution component locations.

The following components make up the power distribution system:

•

MEGA Fuse Junction Block (MFJB), EPA07 only

•

Powertrain Power Distribution Module (PT-PDM)

•

Powernet Distribution Box (PNDB), EPA10 and newer

•

Cab Load Disconnect Switch

•

Auxiliary PDM

MEGA Fuse Junction Block, EPA07

On EPA07 vehicles, the MFJB distributes battery power to the alternator, SAM cab, SAM chassis, and powertrain PDM. Battery power may also be routed to an inverter and a trailer PDM. The MFJB houses up to ﬁve MEGA fuses, and is located on the left frame rail in front of the batteries. See

Powernet Distribution Box, EPA10 and Newer

The PNDB distributes battery power to the SAM cab, SAM chassis, powertrain PDM, and other keep-alive circuits.

The PNDB is mounted in the engine compartment on the frontwall near the steering column. The label on the PNDB fuse cover identiﬁes typical circuits. See

Fig. 3.3.

Power Distribution Modules

Powertrain PDM

The powertrain PDM contains fuses and relays that provide battery and ignition power to the engine, aftertreatment device, transmission, and other powertrain-related circuits. It is mounted in the engine compartment, above the driver-side inner fender.

Fig. 3.1 for

Fig. 3.2.

Auxiliary PDM

The optional auxiliary PDM is used when additional circuit protection is needed for optional features. For example, if a beacon light is added to the Cascadia, it may require an auxiliary PDM. The auxiliary PDM may contain fuses and relays for these devices. It is mounted in the cab, behind the doghouse cover.

Trailer PDM

The optional trailer PDM, mounted on the frame rail, is used to supply trailer power to the chassismounted trailer receptacles. The SAM chassis supplies control signals to the relays in the trailer PDM.

Circuit Protection Features

The SAM chassis and SAM cab may be equipped with self-resetting circuit breakers instead of fuses. Self-resetting circuit breakers are tripped when they reach 170°F (77°C), then self-reset once the temperature drops sufficiently. When the circuit overload is removed, this circuit protection will self-reset. Some of these circuits require the ignition switch to be cycled off then back on again for the self-reset to occur.

Some ECU’s are equipped with a self-resetting circuit breaker removal tool.

WARNING

Turning the cab load disconnect switch (CLDS) 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.

IMPORTANT: The ignition should be turned off before turning the CLDS to on or off.

The CLDS is used to avoid excessive draw on the battery when the vehicle is parked for an extended period of time by disconnecting (or opening) the connection between the battery and the most of the vehicle electrical system.

The CLDS may be mounted:

•

inside the cab on the outboard side of the driver’s seat;

•

at the battery box;

•

outboard on the left frame rail.

Emergency Power Supply

The Cascadia electrical system has an emergency power circuit that supplies battery power for exterior lighting. This assists vehicle visibility in the event a MEGA fuse is open circuit. The emergency power circuit is live even when the CLDS is turned off.

The emergency power supply feature allows for the vehicle to be driven off the highway and for the exterior lighting to remain on in the event of a SAM Cab or SAM Chassis failure. The emergency power supply will cause certain exterior lamps to ﬂash (depending on if it is the SAM Cab or SAM Chassis that failed), indicating that the vehicle is disabled.

Engine Protection System

WARNING

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.

See Fig. 4.5 for an explanation of the aftertreatment 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 derate the engine, allowing it to run at lower rpm and slower vehicle speed. Drive the vehicle to a safe location or to a service facility.

IMPORTANT: Safely bring the vehicle to a stop 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.

Some vehicles may have a shutdown-override switch, which may be used to momentarily override the shutdown sequence. See information regarding the shutdown process.

Chapter 11 for detailed

IMPORTANT: Do not attempt to restart the engine while the vehicle is moving. Bring the vehicle to a safe stop, then restart the engine.

To restart the engine, turn the ignition to OFF, leave it there a few seconds, then turn the ignition to START. The engine will run for a short period and shut down again if the condition does not improve.

Instruments

Standard instruments are present on every vehicle. They are listed here in alphabetical order to make the information easier to ﬁnd.

Optional instruments, typically located on the auxiliary dash panel or right-hand control panel, are not found on every vehicle. They are listed here in alphabetical order, to make the information easier to ﬁnd.

For engines that are EPA10-compliant or newer, the fuel and DEF levels are measured in a dual purpose fuel/DEF level gauge. See

The diesel fuel level is indicated at the top of the gauge, with a low-fuel warning lamp that illuminates amber when the diesel fuel level registers 1/8th of capacity.

The DEF level is indicated in the lightbar on the lower portion of the gauge. There is a low DEF level warning lamp that illuminates amber when the DEF level reaches 10% of capacity. See Chapter 12 for details of the DEF gauge functions.

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 light and audible alert, connected to both the primary and secondary systems, activate when air pressure in either system drops below approximately 70 psi (483 kPa).

4.10

Instruments

When the engine is started, the warning light and audible warning remain on until air pressure in both systems exceeds minimum pressure.

Speedometer

Two speedometer 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.

Transmission Fluid Temperature Gauge

The transmission ﬂuid temperature gauge indicates the transmission lubricant operating temperature. Temperatures vary by application, but the transmission ﬂuid temperature gauge reading should not exceed 250°F (121°C).

Voltmeter

The voltmeter indicates the vehicle charging system voltage when the engine is running and the battery voltage when the engine is off. 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. Cascadia vehicles are equipped with either a voltmeter gauge, or a digital voltmeter readout located on the bottom line of the dash message center.

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 off. Battery voltage under 12.0 volts is considered a low battery, and a completely discharged battery will produce only about 11.0 volts.

If the voltmeter shows an undercharged or overcharged condition for an extended period, have the charging system and batteries checked at an authorized Freightliner service 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 off, the voltmeter shows only the isolated battery voltage and does not indicate the voltage of the engine-starting batteries.

NOTICE

A sudden increase in transmission ﬂuid 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.

Turbocharger Boost Pressure Gauge

A turbocharger boost pressure gauge indicates the pressure in the intake manifold, in excess of atmospheric pressure, being created by the turbocharger.

Cruise Control

WARNING

Do not use the cruise control system when driving conditions do not permit maintaining a constant speed, such as in heavy traffic or on roads that are winding, icy, snow-covered, slippery, or roads with a loose driving surface. Failure to follow this precaution could cause a collision or loss of vehicle control, possibly resulting in personal injury or property damage.

NOTICE

When the cruise control is engaged, do not attempt to shift gears without using the clutch pedal. Failure to follow this precaution will result in a temporarily uncontrolled increase in engine speed. Transmission damage and gear stripping could result.

IMPORTANT: On vehicles equipped with VORAD Collision Warning System with SmartCruise, see cruise control.

NOTE: If the vehicle is equipped with a Detroit multifunction control, setting the cruise control with the engine brake on will activate Descent Control Mode. Moving the lever to the top position will resume the set cruise speed. Moving the lever down to engage the engine brake after the cruise control has been set will activate Deceleration Mode. See "Descent Control and Deceleration Modes, Detroit™Automated Transmissions" in this chapter.

The cruise control is operated by four buttons mounted in the left-hand button pod of the steering wheel. See

Run Smart Predictive Cruise

Predictive Cruise Control (PCC) is an optional fuel savings application that adjusts vehicle speed predictively, based on the approaching road. Using 3D digital map technology and GPS, PCC evaluates the upcoming road grade about a mile in advance to determine the most fuel-efficient vehicle speed. Vehicles equipped with PCC have a sticker on the dash. See

04/15/2009 f100149

Fig. 5.23, Run Smart Predictive Cruise Control Sticker

The 3D digital map database contains proﬁle information for over 200,000 highway miles (322,000 km) in the 48 contiguous United States. PCC will vary the set cruise speed by up to 6% depending on the approaching road grade. If the engine brake is enabled, PCC will automatically engage the engine brake when actual vehicle speed exceeds the cruise set speed by 6%. This is different from conventional cruise control, which maintains the speed set by the driver.

Fig. 5.23.

™

WARNING

Apply the brakes and downshift as necessary when driving on downhill grades. PCC does not adequately control vehicle speed on steep downhill grades. Failure to use normal braking techniques when PCC is active could result in personal injury and vehicle damage.

IMPORTANT: PCC adjusts the vehicle set speed to achieve maximum fuel economy, but it does

5.12

Driver Controls

not account for traffic ﬂows or surrounding vehicles.

Driver interaction with PCC is the same as conventional cruise control, using the standard cruise control buttons. In the event of a problem with PCC, or when driving on a road with no proﬁle information available, the system reverts to conventional cruise control.

Cruise Control ("CC") Limiter

On vehicles equipped with a CC Limiter (or CC Band) switch (see control limiter allows the vehicle to exceed the set cruise control speed before engine braking is applied. The CC limiter switch provides more ﬂexibility to the existing cruise control limit function, allowing the driver to tune the cruise function to better suit driving preferences and conditions. To select a limit, use the three-position CC Limiter switch on the dash.

Descent Control and Deceleration Modes, Detroit™Automated Transmissions

On vehicles equipped with a Detroit multifunction control ( tions for engine brake control change when cruise control is set. Two distinct modes can be activated:

Descent Control Mode

Descent Control Mode keeps the vehicle speed below the set cruise speed on a downhill.

To activate Descent Control Mode, set the cruise control speed with the engine brake on ( positions 1, 2, or 3). In this mode, all three levels of engine braking will be employed to to keep the speed below the set cruise speed. This mode will not keep the speed above the lower limit of the set speed, so it is possible to eventually coast to a stop, unless the lever is moved to "engine brake off" (position 0), or throttle is applied. After throttle application, the Descent Control Mode is resumed.

Moving the lever to "engine brake off" (position 0) cancels Descent Control Mode and resumes cruise speed. To reactivate Descent Control Mode, reset the cruise control speed with the lever in position 1, 2, or

VORAD VS-400 System

WARNING

The VORAD VS-400 System is intended solely as an aid for an alert and conscientious professional driver. It is not intended to be relied upon to operate a vehicle. Use the system in conjunction with rearview mirrors and other instruments to safely operate the vehicle. Operate a vehicle equipped with the VS-400 System in the same safe manner as if the CWS were not present.

The VS-400 System is not a substitute for safe, normal driving procedures, nor will it compensate for any driver impairment such as drugs, alcohol, or fatigue.

The VS-400 System may provide little or no warning of hazards such as pedestrians, animals, oncoming vehicles, or cross traffic.

Failure to drive safely and use the system properly could result in personal injury and/or death and severe property damage.

The VORAD VS-400 system is an on-board radar system that monitors traffic conditions, warning the driver of potentially hazardous driving situations.

The collision warning system (CWS) tracks objects ahead of the vehicle, warning the driver with visual and audible indicators whenever following distances become unsafe.

SmartCruise® adjusts the vehicle’s cruise speed in order to match the speed of traffic ahead, allowing the driver to maintain a safe following distance while cruise control is engaged.

The optional side object detection system warns of unsafe lane changes by detecting vehicles that may be difficult to see in adjacent lanes.

The VORAD VS-400 system performs in fog, rain, snow, dust, smoke, and darkness. The VS-400 system becomes active whenever the ignition key is switched to ON.

Driver Interface Unit

The driver interface unit (DIU) provides visual and audible alerts, along with system status information. The DIU also provides an interface for changing system settings. Menu selections are made by pressing

the up and down arrow buttons, and the OK button.

SmartCruise

When approaching slower moving traffic with the vehicle’s cruise control engaged, SmartCruise adapts the engine cruise speed to that of the closest vehicle ahead, allowing the vehicle to maintain a safe following distance without disengaging the cruise control. The DIU will display the SmartCruise status screen indicating the vehicle’s current set cruise speed.

Once the speed of traffic ahead increases beyond the adapted engine cruise speed, the original cruise control set speed re-engages.

When SmartCruise is engaged, depressing the accelerator pedal will override the SmartCruise and will cause the vehicle to accelerate. Depressing the brake or clutch pedals will deactivate SmartCruise.

When approaching a slow moving or stopped vehicle ahead, SmartCruise will attempt to maintain the minimum following distance by reducing the engine cruise speed and engaging the engine brake, if necessary. If SmartCruise is unable to maintain the minimum following distance, the driver will be alerted by the CWS headway alerts until the driver takes control or conditions clear.

Side Object Detection

The optional side object detection system may be installed on one or both sides of the vehicle. The radar sensor(s) are located on the side of the vehicle, while the sensor display unit is mounted on the A-pillar. See

The side sensor display unit uses two lights to display the status of the side sensor(s). The yellow light indicates the system is active, but no objects are detected. The red light indicates that the side sensor detects an object. If the vehicles turn signal is active

Driver Assistance Features

•

On approaching a steep hill, objects above the beam cannot be detected. Generally, the beam hitting the road surface does not cause an alarm.

•

The side sensor only detects objects within its ﬁeld of view, next to the tractor. A vehicle behind the ﬁeld of view will not be detected.

•

The side sensor range is set to detect average-sized vehicles 2 to 10 feet (0.5 to 3 meters) away in the adjacent lane.

•

The radar beam will detect near range cut-ins of approximately 30 feet (9 meters) or less, depending on the angle of entrance into the lane in front of your vehicle.

•

A continuous ﬁxed object on the right side of the vehicle such as a guard rail, wall, tunnel, or bridge may cause the side sensor alert light to stay on.

WARNING

Special Road Situations

Certain road situations may affect the system’s ability to detect objects. These situations include the effects of curves, dips, and hills which can provide an unexpected result.

NOTE: A warning may sound when an object is detected in front of the vehicle even though the driver intends to turn away or stop before reaching the object.

•

When an object is detected in a very sharp right- or left-hand turn, the audible alarm will not sound.

•

When approaching a curve, alarms may sound and lights illuminate, because of an object off the road directly in line with your vehicle. This will not occur when the brakes are applied.

•

When approaching a roadway descending to a lower elevation, elevated obstacles such as overpasses and overhead signs may be detected.

•

Vehicles cannot be detected on the other side of a hill. An alarm will not sound until the object is within the antenna assembly’s ﬁeld of view.

Heavy rain or water spray at the side sensor may cause both the yellow and red lights on the side sensor display to illuminate at the same time. Under these conditions the system is temporarily unable to provide adequate warnings.

Failure to drive safely and use the system properly could result in personal injury and/or death and severe property damage.

Maintenance

Keep the antenna and side sensor free of buildup of mud, dirt, ice, or other debris that might reduce the system’s range.

Failure Display Mode/Fault Codes

The VS-400 performs internal diagnostics at powerup, then continuously monitors system components thereafter.

If a failure is detected, depending on what features are affected, the DIU displays a screen similar to

Fig. 6.15, blinks the orange fault light, and sounds a

tone. Press the OK button to acknowledge the fault.

After the fault has been acknowledged, the DIU will attempt to return to normal operations. The orange LED is continuously illuminated while the fault persists. If the fault disappears, the VS-400 transmits a

OnGuard™Collision Safety System

Meritor WABCO OnGuard is a forward-looking radarbased adaptive cruise control and collision safety system with active braking. The system includes a collision warning system (CWS), adaptive cruise control (ACC) with active braking, and a collision mitigation system (CMS).

The system performs in fog, rain, snow, dust, smoke, and darkness. To be detected, objects must be within the radar ﬁeld of view and provide a surface area that can reﬂect the radar.

Standby

When no object is detected, the display shows that the CWS is on and the radar is searching. See

Fig. 6.17.

Object Detected

When an object is detected in the lane ahead, the display shows that the CWS is on and the radar is tracking an object at the speed shown. See

Fig. 6.18.

If the following distance between the vehicle and the object is too close, the CWS will emit an audible alert and the display background will turn yellow. The alert will end when vehicle speed drops below the object speed and the following distance is increased.

Collision Warning

If the object is traveling slower than the driver’s vehicle, the CWS warns of an impending collision by emitting an urgent audible alert and displaying the collision warning symbol with a red background. See

Adaptive Cruise Control (ACC)

ACC is a radar-based system that works in conjunction with conventional cruise control to maintain the set cruise speed when no vehicle is being tracked, and maintains a minimum following distance when an object is being tracked. The minimum following distance is maintained by automatically decelerating the vehicle using throttle, engine, and service brakes without driver intervention. When the object is no longer being tracked, the set cruise control speed resumes automatically.

Standby

When no object is detected, OnGuard ACC operates similarly to conventional cruise control. The cruise control set speed is shown on the OnGuard display unit. See

Object Detected

When an object is detected in the lane ahead, the display shows that ACC is on and the radar is tracking an object at the speed shown. See

Lane Departure Warning Controls

The Lane Guidance lane departure warning system monitors the vehicle’s position within the roadway lane markings and sounds a warning in the cab when the vehicle is about to stray outside its lane, provided the turn signal is not on and the vehicle is traveling at least 37 mph (60 km/h). The system includes a digital camera mounted high near the center of the windshield inside the cab and speakers that emit a sound similar to a rumble strip. The sound is made on the side of the vehicle it’s straying toward, prompting the driver to respond and steer away from the sound and back into the center of the correct lane.

6.10

Driver Assistance Features

WARNING

The lane departure warning system is intended only as an aid for a conscientious and alert driver. The system may not indicate lane departures under certain conditions. Read carefully the information in this manual to understand the circumstances under which this system may not provide adequate lane departure warnings. Do not rely solely on the system to safely operate the vehicle. The system does not warn of all possible hazards. For example, the system cannot prevent an accident if the driver is impaired or not driving safely.

The lane departure warning system is not a substitute for safe driving procedures.

Failure to drive safely and use the system properly could result in personal injury and/or death and severe property damage.

The lane departure warning system powers up each time the ignition is turned to ON. The system conducts a self test, and initiates test tones from the left speaker and then the right speaker. Once the vehicle is started and the system is ready, the LED in the switch illuminates.

Press the LANE ALERT switch to temporarily disable the lane departure warning system. See Some vehicles are equipped with a timer that automatically re-enables the warning system after 15 minutes. On all other vehicles, the warning system will remain disabled until the driver enables the system by pressing the LANE ALERT switch again, or the ignition is cycled off and then on.

Fig. 6.26.

When the vehicle approaches the lane markings on either side, the system sense the activation of a turn signal. If a turn signal has not been activated, the system initiates the audible warning to alert the driver that the vehicle is departing its current lane of travel.

The LANE SRCHNG warning light illuminates to indicate the system is not fully functional. When the warning light is on, the system audible alert may not indicate a lane departure. Conditions that can cause the warning light to illuminate include:

•

The system is unable to detect lane markings.

•

Vehicle speed is less than 37 mph (60 km/h).

•

A system problem is detected.

Roll Stability System

The roll stability system may include the roll stability advisor (RSA) only, or it may also include the roll stability control (RSC).

Driver Assistance Features

Roll Stability Advisor

IMPORTANT: This is not an advance warning system. The roll stability advisor displays a message only after the driving maneuver is completed.

The roll stability system uses a lateral-acceleration sensor that monitors rollover risk. Shortly after a curve, lane change, or other driving maneuver that results in a rollover-risk detection, a dash warning light illuminates, an audible tone sounds, and a driver advisory message is displayed in the driver message center. The purpose is to advise the driver that the previous maneuver produced a rollover risk.

The roll stability advisor displays different text messages depending on the severity of the risk of each occurrence of risky driving. From the highest risk level to the lowest risk level, the system will sound an audible alert, and display a message, as shown in

Fig. 6.29.

NOTE: The system will calculate and recommend a speed reduction value. It may be different than the values shown here.

Bring the vehicle to an authorized service facility if a system failure message is displayed.

Roll Stability Control

WARNING

The Roll Stability Control system is intended only as an aid for a conscientious and alert driver. Carefully read the information in this manual to understand this system and its limitations. The Roll Stability Control system is not a substitute for safe driving procedures. Failure to drive safely, and use the system properly, could result in personal injury and/or death and property damage.

The roll stability control system automatically reduces engine power, applies the engine brake, and/or applies the tractor and trailer brakes when the acceleration sensor detects that the vehicle is at risk of rolling over. The control can intervene even before an advisory message is displayed.

The dash indicator light illuminates whenever the roll stability control system intervenes.

Hard-Braking Advisor

The hard-braking advisor uses the information from the ABS wheel speed sensors to determine when braking is severe enough to produce lockup at one or more wheels on the tractor, and/or very rapid vehicle deceleration. Shortly after a hard-braking event occurs, an advisory message is displayed in the driver message center, indicating that the braking behavior was too aggressive for the current road surface conditions. This system is not a replacement for a driver’s good judgment. Sometimes it is necessary to brake hard.

From the highest risk level to the lowest risk level, the system will sound an audible alert, and display a message, as shown in

Enhanced Stability Control

WARNING

Enhance Stability Control (ESC) is intended only as an aid for a conscientious and alert driver. Carefully read the information in this manual to understand this system and its limitations. ESC is not a substitute for safe driving procedures. Failure to drive safely, and use the system properly, could result in personal injury and/or death and property damage.

ESC offers the full capability of RSC (shown above) with the added capability of complete directional stability (yaw control) in oversteer and understeer conditions to reduce the likelihood of drift-out or jackknife. The system determines where the driver is attempting to steer the vehicle and how much brake demand is required in order to more precisely control the vehicle in an emergency situation.

6.13

ESC works by constantly comparing the driver’s intention with the vehicle’s actual behavior. The system does this by monitoring systems such as wheel speed, steering angle, yaw rate, lateral acceleration, throttle position, and brake application. A central microcomputer analyzes the collected data and triggers a response to keep the vehicle on course when an unstable condition is detected.

When the system detects that the vehicle is at risk of oversteering or understeering, it applies individual tractor wheel end brakes and trailer brakes, activates the engine retarder (if equipped), and/or cuts engine power, depending on the severity. As a result, the driver has full control over the vehicle until the system detects a potential risk and intervenes accordingly. ESC operates automatically; the driver does not monitor or activate the system.

Seats, General Information

Unless otherwise noted, all seat adjustments should be made while seated and before the engine is started.

Due to the high degree of 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 back wall. Use care when adjusting the seat to prevent damage to the seat and the cab interior.

WARNING

Keep hands, tools, and other objects away from the scissor points under the seats. Failure to do so could cause personal injury.

The following is a description of adjustments that can be made to various Freightliner-installed seats. Not all seats have all of the adjustments listed below. See

Fig. 7.1.

•

Backrest Tilt enables the backrest to pivot forward or backward.

•

Lumbar Support changes the shape of the backrest to give more or less support to the occupant’s lumbar (lower back) area. This adjustment is either mechanical or air controlled, depending on the seat model.

•

Fore/Aft Isolator feature reduces the amount of road shock by isolating the occupant from the motion of the vehicle, and allowing the upper seat to move in a simple pendulum motion. A lockout feature is used whenever the isolator is not desired.

•

Height Adjustment moves the entire seat up or down. The adjustment is either manually- or air-controlled, depending on the seat model.

•

Bottom Cushion Angle (fore-and-aft bottom cushion height)

enables the occupant to raise or lower the front or back of the bottom cushion. This adjustment is easier to perform when all weight is removed from the seat.

Seat Belts and Tether Belts

Seat belt assemblies are designed to secure persons in the vehicle to help reduce the chance of injury, or the amount of injury, resulting from accidents or sudden stops. For this reason, Daimler Trucks North America LLC (DTNA) urges that the driver and all passengers, regardless of age or physical condition, use seat belts when riding in the vehicle.

7.5

Seats and Restraints

WARNING

Always use the vehicle’s seat belt system when operating the vehicle. Failure to do so can result in severe personal injury or death.

Seat belt assemblies in DTNA vehicles meet Federal Motor Vehicle Safety Standard 209, "Type 1" and "Type 2" requirements.

When transporting a child, always use a child restraint system or the vehicle seat belts as appropriate. To determine whether a child restraint system is required, review and comply with applicable state and local laws. Any child restraint used must comply with Federal Motor Vehicle Safety Standard 213, "Child Restraint Systems." When providing a child restraint system, always 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 Inspection

WARNING

Inspect and maintain seat belts. When any part of a seat belt system needs replacement, the entire seat belt must be replaced, both retractor and buckle side. Any time a vehicle is involved in an accident, and the seat belt system was in use, the entire vehicle seat belt system must be replaced before operating the vehicle. Do not attempt to modify the seat belt system; doing so could change the effectiveness of the system. Failure to replace worn or damaged seat belts, or making any modiﬁcations to the system, may result in personal injury or death.

Inspect the seat belts and tether belts (if so equipped).

Check the web for fraying, cuts, extreme dirt and dust, or for severe fading from exposure to sunlight, especially near the buckle latch plate and in the D-loop guide area.

Check operation of the buckle, latch, Komfort Latch or Sliding Komfort Latch (if equipped), web retractor, and upper seat belt mount on the door pillar. Check all visible components for wear or damage.

Check the seat belt and tether belt connection points and tighten any that are loose.

Seat Belt Operation

WARNING

Wear three-point seat belts only as described below. Three-point seat belts are designed to be worn by one person at a time. In case of an accident or sudden stop, personal injury or death could result from misuse.

Fasten the seat belts before driving. Fastening a three-point seat belt while driving creates a hazard.

When engaged and used properly, the Komfort Latch

Fig. 7.7) and the Sliding Komfort Latch (Fig. 7.8)

( introduce a small amount of slack into the seat belt, resulting in a more comfortable ride.

Slowly pull the link end of the 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. See

Fasten the seat belt by pushing the latch into the buckle. Listen for an audible click.

for approximately 1 inch (2.5 cm) of slack between your chest and the shoulder harness. Once engaged, the latch will allow you to lean forward about 5 inches (13 cm) without having to reset the latch. Leaning forward more than 5 inches (13 cm) will disengage the Sliding Komfort Latch, requiring it to be reset.

If equipped with a Komfort Latch, pull on the shoulder strap to lessen the pressure of the strap on your shoulder and chest. Allow no more than 1 inch (2.5 cm) of slack between your chest and the shoulder harness. More slack can signiﬁcantly reduce the seat belt effectiveness in an accident or a sudden stop. While holding the belt slack, press the Komfort Latch lever up, clamping the seat belt webbing (

Steering Wheel Air Bag

Operation

NOTE: Only vehicles with the letters "SRS" molded into the steering wheel center pad are equipped with a steering wheel air bag.

The air bag, when used with seat belts, provides additional protection to the driver in severe frontal collisions. Steering wheel air bags are designed to inﬂate only in severe frontal collisions. The driver and the

7.8

Seats and Restraints

passenger should always wear seat belts. The steering wheel air bag will activate during a collision even if the seat belts are not fastened, but the system is designed to provide protection to the occupant only when the seat belts are fastened.

WARNING

Keep all heavy objects in the cab secured. Do not place objects on the steering wheel or between you and the steering wheel. Any such objects may cause harm during an accident. Keep your hands on the sides and lower portion of the steering wheel. Failure to follow these instructions may result in death or personal injury.

For maximum protection in a collision, always be in a normal seated position with your back against the seat back and your head upright. Fasten your seat belt and ensure that it is properly positioned on your body as described under the "Seat Belt Operation" heading. Since the air bag inﬂates with considerable speed and force, a proper seat position will help keep you a safe distance from the inﬂating air bag.

Inspection and Service

WARNING

Do not attempt to service or modify the air bag system. Unintentional or improper air bag deployment could cause severe bodily injury or death. Contact an authorized Freightliner service facility for all service and maintenance.

The air bag system contains components that use combustible chemicals. Do not cut, drill, braze, solder, weld, strike, or probe the air bag components. Keep all liquids and chemicals away from air bag components.

The surface of the deployed air bag may contain small amounts of sodium hydroxide (which is a by-product of the gas generant combustion) and metallic sodium. Sodium hydroxide may be irritating to the skin and eyes. Immediately wash your hands and exposed skin areas with a mild soap and water. Flush your eyes immediately if exposed to sodium hydroxide.

The operational readiness of the air bag system is indicated by the supplemental restraint system (SRS) indicator on the dash. The SRS indicator illuminates

for several seconds when the ignition is turned on, and then it goes off. The indicator will remain on if there is a problem with the air bag system. The vehicle should be serviced if the SRS indicator does not illuminate when the ignition is turned on, or if the SRS indicator remains on.

The air bag module may contain perchlorate material; for information, see

RollTek Rollover Protection System

Identiﬁcation

Only seats with the RollTek module under the seat and the molded side-roll air bag cover on the upper side of the seat back are equipped with the RollTek rollover protection system; see may be installed in one of the following conﬁgurations:

•

driver seat only or driver and passenger seats

•

driver seat only, with an optional steering wheel frontal air bag

•

driver and passenger seats, with an optional steering wheel frontal air bag

Operation

The RollTek system, when used with seat belts, provides additional protection to the driver and passenger (if equipped with a passenger-side system) in rollover accidents. The RollTek system provides a signiﬁcant increase in seat stability during a rollover. Vehicles equipped with RollTek rollover protection have a sensor mounted in the seat base that activates the side-roll air bag and seat pull-down device during a rollover.

When the RollTek module senses a rollover, the module triggers gas cylinders mounted in the base of the seat. The gas cylinders activate the power cinches that then tighten the lap and shoulder belts against the occupant of the seat and lower the seat suspension, moving the occupant down and away from the steering wheel and ceiling. The side-roll air

or block the side-roll air bag. Objects that block the side-roll air bag may prevent proper inﬂation and could result in serious injury or death.

The RollTek system will activate during a rollover even if the seat belts are not fastened, but the RollTek system is only designed to provide protection to the occupant when the seat belts are fastened.

For vehicles with the RollTek system(s) only, device(s) deploy as follows:

•

Rollover Crash—occupant seat belt pretensioning, seat pretensioning, and side-roll air bag at the proper time

•

Frontal Crash—no devices deployed
