BEFORE DRIVING YOUR VEHICLE
TOWING TRAILERS
WARNING
Towing trailers beyond the maximum recom-
mended 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 Final-
stage 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 OPERA TION
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-
3 - 11
BEFORE DRIVING YOUR VEHICLE
mance diesel engine oil and Ultra
Low Sulfur Diesel (ULSD) fuel.
HANDLING OF THE EXHAUST EMISSION CONTROL SYSTEM
The exhaust emission control sys-
tem reduces PM (Particulate Matter) and NOx by collecting PM
through the filter that is installed in
the PM reduction device and by
dissolving NOx into water and
nitrogen using the aftertreatment
SCR system.
When a certain amount of soot
accumulates in the DPF, the DPF
system automatically switches into
the cleaning mode to burn (regenerate) the collected soot. The frequency of the occurrence of the
aftertreatment DPF regeneration
differs according to the manner in
which the vehicle is driven.
The aftertreatment SCR system
reduces NOx by adding a mixture
of air and diesel exhaust fluid
(DEF) in the exhaust muffler to
make NOx that is included in
exhaust gas and is dissolved into
water and nitrogen.
The following must be observed to
prevent malfunctioning of this system.

BEFORE DRIVING YOUR VEHICLE
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
NOTE:
If there are flammable materi-
als around the vehicle, a fire
may occur. This could cause
burns from the heated exhaust
gas.
Depending on the driving condi-
tions, 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 aftertreat-
ment 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 clean-
ing 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 clean-
ing 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
NOTE:
CAUTION
If driving is continued, clog-
ging in the DPF or a system
malfunction may occur.
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 after-
treatment 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 neces-
sity because they are damaged,
use UD Trucks genuine parts.
