TOWING TRAILERS

WARNING

Towing trailers beyond the maximum recommended trailer weight which exceeds the limit of the vehicle’s GCWR, GVWR, GAWR(s) or tire ratings could result in engine damage, transmission damage, structural damage, loss of vehicle control, vehicle rollover and personal injury.

Definitions:

GAWR (Gross Axle Weight Rating) — is the maximum allowable weight that can be carried by a single axle (front or rear). These numbers are shown on the Simplified Final-stage Vehicle Certification Label that can be found on the inside of the driver’s door or the door frame. The total load on each axle must never exceed its GAWR.

GCWR (Gross Combined Weight Rating) — is the maximum allowable weight of the vehicle and the loaded trailer — including all cargo and passengers — that the vehicle can handle without risking damage (Important: The towing vehicle's braking system is rated for operation at GVWR, not at GCWR). Separate functional brakes should be used for safe control of towed vehicles and for trailers where the GCW (Gross Combined Weight) of the towing vehicle plus the trailer exceed the

GVWR of the towing vehicle. The GCW must never exceed the GCWR.

GVWR (Gross Vehicle Weight Rating) — is the maximum allowable weight of the fully loaded vehicle (including all options, equipment, passengers, and cargo).

CAUTION

Exceeding the Tire Rating or Simplified Finalstage Vehicle Certification Label vehicle weight rating limits could result in substandard vehicle handling or performance, engine, transmission and/or structural damage, serious damage to the vehicle, loss of control and personal injury.

EGR SYSTEM OPERATION

WARNING

Do not carelessly touch the EGR system components (EGR valves, EGR adapter, EGR piping, EGR cooler, coolant piping, etc.) when the engine is hot, such as during operation and immediately after driving. These components are hot and touching them could cause burns, therefore touching them is very dangerous.

CAUTION

Do not rest your feet, etc., on the EGR system components. Doing so could damage the EGR system components.

Overheating of the engine could damage the EGR system components, so have them inspected and serviced by the nearest authorized UD Trucks dealer.

When a certain amount of soot accumulates in the aftertreatment DPF, the DPF automatically goes into the regeneration mode to burn the collected soot. To obtain the expected DPF performance, please observe the following precautions. The frequency of the occurrence of the aftertreatment DPF regeneration mode differs according to how you drive the vehicle.

UD TRUCKS, US2010

EMISSIONS SOLUTION

The exhaust aftertreatment system virtually eliminates exhaust smoke. White exhaust vapor (water condensation) may be visible during a cold start. If black exhaust smoke visible during engine operation, this indicates a problem with the exhaust aftertreatment system. Take the vehicle to an authorized UD Trucks dealer immediately.

Vehicles equipped with a 2010 emission compliant engine have an exhaust aftertreatment system which includes an aftertreatment Selective Catalytic Reduction (SCR) system and a Catalyzed aftertreatment Diesel Particulate Filter (DPF). The Aftertreatment DPF takes the place of the standard muffler, and it reduces soot and particulate emissions into the atmosphere.

Soot and other particulate matter are collected by a filter where it is eventually oxidized.

Vehicles equipped with an aftertreatment DPF require the use of UDXtra (or VDS-4) specification high perfor-

Precautions on handling the DPF

When a certain amount of soot that is included in the exhaust gas accumulates in the aftertreatment DPF, the DPF automatically burns (regenerates) the collected soot.

This prevents the excessive accumulation of soot and keeps the cleaning function of the DPF in good condition.

The DPF automatically burns (regenerates) the collected soot.

WARNING

Immediately after the vehicle is stopped or while the system is in the regeneration, the area around the muffler and exhaust gas are extremely hot. Do not stop the vehicle in a location where there are flammable materials such as dried grass or paper waste.

3 - 13

BEFORE DRIVING YOUR VEHICLE

If there are flammable materials around the vehicle, a fire may occur. This could cause burns from the heated exhaust gas.

NOTE:

Depending on the driving conditions, the burning (DPF regeneration) of the soot collected in the DPF may not be completed. When both the DPF clogging warning light and the indicator light that is built in the manual forced regeneration switch blink, press the exhaust gas cleaning device switch to manually clean the soot.

While operating the aftertreatment DPF, the engine speed at idle may increase under the following conditions. This is due to a temperature increase of the exhaust gas in order to burn (regenerate) the collected soot. This does not indicate a malfunction.

The engine exhaust gas temperature is low for a long

period of time. (For example, the engine idles too long.)

If a gear is engaged to drive the vehicle, the operation of the device will stop. However, if the processing time is not sufficient to satisfy a specified duration, the operation of the device will resume after stopping the vehicle.

The cleaning mode automatically turns on while driving.

When the DPF clogging warning light blinks, perform the DPF regeneration manually.

When both the DPF clogging warning light that is located in the combination meter and the indicator light that is built in the manual forced regeneration switch blink, immediately perform manual cleaning of the aftertreatment DPF to burn (regenerate) the soot that has collected.

WARNING

Do not perform manual cleaning in a location with poor ventilation. Exhaust gas may cause carbon monoxide poisoning especially in an enclosed location, such as in a garage, indoors, etc.

Do not perform manual cleaning in a location where there are flammable materials such as dried grass or paper waste. The temperature of the exhaust gas and the area around the exhaust pipe and muffler become high during cleaning. Therefore, if there are flammable materials nearby, a fire may occur.

In addition, never allow your body to contact exhaust gas and the area around the exhaust pipe and muffler. Doing so may cause burn injuries.

If the vehicle is stopped over a road surface that is painted, the road surface may be discolored.

3 - 14

BEFORE DRIVING YOUR VEHICLE

CAUTION

If driving is continued, clogging in the DPF or a system malfunction may occur.

NOTE:

The engine speed increases while performing manual DPF regeneration. This is due to a temperature increase of the exhaust gas in order to burn (regenerate) the collected soot. This does not indicate a malfunction.

While performing manual aftertreatment DPF regeneration, the aftertreatment hydrocarbon doser system supports the manual DPF regeneration by injecting fuel in the exhaust pipe.

Handling of the aftertreatment diesel exhaust fluid (DEF) dosing system

The DEF dosing system (DEF pump, DEF dosing valve) continues to operate for approximately 120 seconds after the ignition key is turned to OFF position. Therefore, wait for at least 120 seconds before disconnecting the battery cable or electrical system connectors when servicing the vehicle, etc.

Handling of the muffler

The muffler that is equipped with the aftertreatment DPF for the PM reduction device needs to be cleaned regularly to maintain its performance (either 155,000 miles [250,000 km] or 4,500 hours, whichever comes first). This is because unburnable ash that is different from burnable soot will accumulate in the DPF.

For details about cleaning of the muffler equipped with the DPF,

contact your nearest authorized UD dealer.

For the muffler that is equipped with the SCR catalyst system, no inspections and maintenance are basically required.

If they must be replaced by necessity because they are damaged, use UD Trucks genuine parts.
