IMPORTANT INFORMATION ON
VEHICLE LOADING
OVERLOADING
Your dealer can advise you of the proper loading conditions for your
vehicle. Using selected heavier suspension components for added
durability may not increase any of the weight ratings shown on the
Vehicle Identification Number (VIN) and Weight Rating Plate.
CAUTION: The components of your truck are designed to provide
satisfactory service if the vehicle is not loaded in excess of either
the gross vehicle weight rating (GVWR) or the maximum front and
rear gross axle weight ratings (GAWRs). These ratings are listed
on the Vehicle Identification Number (VIN) plate, which is located
on the left side rear pillar panel below the striker.
Overloading can result in loss of vehicle control and personal
injury, either by causing component failures or by affecting vehicle
handling. It can also shorten the service life of your vehicle.
55702_Sec00_'08 08.2.12 9:41 AM Page 4
0-5
MAXIMUM FRONT AND REAR AXLE WEIGHTS
The weight of the cargo load must be properly distributed over both
the front and rear axles. The VIN and Weight Rating Plate show the
maximum weight that the front axle can carry (front GAWR). It also
shows the maximum weight that the rear axle can carry (rear GAWR).
The GVWR is the maximum permissible loaded weight of the vehicle
and takes into account the capabilities of the engine, transmission,
frame, springs, brakes, axles and tires. Actual loads at the front and
the rear axles can only be determined by weighing the vehicle. This
can be done at highway weigh stations or other such places. See your
dealer for help. The cargo load should be distributed on both sides of
the center line as equally as possible.
EFFECT ON WARRANTY
Your new vehicle limited warranty does not cover any part or
component of your vehicle which has been subject to misuse or abuse.
Any part or component which malfunctions because of overloading will
be deemed to have been subject to misuse and/or abuse.
55702_Sec00_'08 08.2.12 9:41 AM Page 5
0-6
Your VIN and Weight Rating Plate will specify the following:
TIRES
The tires on your truck must be of the proper size and properly
inflated for the load that you are carrying. The VIN and Weight Rating
Plate shows the originally equipped tire size and recommended
inflation pressures.
The tire inflation tables in Section 6 show the load limits for various
size tires at various inflation pressures.
VEHICLE IDENTIFICATION NUMBER
(VIN) AND WEIGHT RATING PLATE
Your VIN and Weight Rating Plate shows the GVWR (Gross Vehicle
Weight Rating) and the front and rear GAWRs for your vehicle.
Gross Vehicle Weight (GVW) is the weight of the originally equipped
vehicle and all items added to it after it has left the factory. This would
include bodies, liftgates, refrigeration systems, etc., winches, booms,
etc., the driver and all occupants, and the load the vehicle is carrying.
The GVW must not exceed the GVWR. Also, gross weight on each of
the front and rear axles must not exceed the front and rear GAWRs
respectively.

SECTION 1
BEFORE DRIVING YOUR VEHICLE
DRIVER DAILY CHECKLIST
Be sure you know how to use your truck and its equipment before
operating it.
BEFORE ENTERING THE TRUCK
1. See that windows, mirrors, lights and reflectors are undamaged,
clean and unobstructed.
2. Check tires for damage and proper air pressure. Check that all
wheel nuts are in place.
3. Look for fluid leaks.
4. Be sure that the tilt cab is securely locked in the lowered position.
5. Inspect the exhaust system, checking that the tailpipe is clear.
START-UP
1. Check that all warning lights work (and that the brake alarm
buzzer works as described under that topic in this manual) when
the key is turned to “ON”, and hold until the glow plug indicator
light goes off, then “START”. The “BRAKE” system warning light
should stay on when the parking brake is applied.
2. Check all gauges (including the fuel gauge) and indicator lights.
3. Adjust the seat.
4. Be sure that the adjustable steering column is in the locked
position.
5. Check and adjust mirrors.
FINAL WALK-AROUND CHECK
Set the parking brake.
1. Look for leaks, now that the engine is running.
2. Check that all lights work.
3. Check that doors and covers are in place; and any emergency
equipment is complete.
4. Be sure everything is properly stowed.
5. Check the area under the truck, and behind it if you are about to
back up.
BEFORE DRIVING OFF
Do not drive the truck until the engine has had sufficient time to
circulate the lubricant oil. This usually requires 30 sec. to 2 minutes
depending on ambient conditions.
NOTICE: This will help reduce white start-up smoke.
55702_Sec01_'08 08.2.12 9:43 AM Page 1

1. Lock all doors.
2. Always properly fasten your seat belt. Check that the seat belt for
any other occupant is fastened properly. Never let anyone ride any
place in or on this vehicle where there is no lap belt or lapshoulder belt.
3. Push down on the brake pedal, release the parking brake, and
check that the “BRAKE” system warning light goes out. If the light
stays on, the vehicle should not be driven until the condition is
corrected.
These checks are in addition to, not instead of, the Bureau of Motor
Carrier Safety requirements. See related topics under “Maintenance
Schedule” in Section 5, especially if problems are found.
One key can operate all the locks on the vehicle. Keep one of the
two keys provided as a spare. The key code is stamped on the tag.
For vehicle security:
• Record the key code numbers.
• Keep the key code plate in a safe place (such as your wallet), NOT
IN THE VEHICLE.
• Be sure to include the key code plate when the vehicle is transferred.
If the original keys are lost, duplicates can be made using the key
codes stamped on key code plate. Contact any authorized Isuzu dealer
or a locksmith.

SEATBACK LATCH (DRIVER)
The seatback latch of the driver seat is designed to limit forward
movement of the seatback during a sudden slowing of the vehicle. Tilt
the seatback to gain access to the area behind it.
The seatback latch release lever is located at the outboard side of
the seat at the base of the cushion. Raise the lever, adjust the
seatback, and release the lever.
After adjusting the seatback, push it back and forth to be sure it is
locked. Take the vehicle to your dealer for servicing if your seatback
does not lock.
Seatback Position When Moving
CAUTION: To reduce the risk of sliding under the lap belt during a
collision, an occupied reclining seat should not be reclined any
more than needed for comfort. The seatback and seat belts provide
best restraint only when the rider is sitting well back and straight
up in the seat. (The lap belt is designed to spread the force of a
collision over the hipbone. If you are reclined, the lap belt may slide
past your hips and apply restraint forces directly to the abdomen.
Therefore, in the event of a collision, the risk of personal injury will
increase with increasing recline of the seatback.)
Do not adjust the reclining seatback on the driver’s seat while the
vehicle is moving. The seatback could jerk and cause a loss of control.

SEAT BELT SYSTEMS
NEVER:
• Put the lap portion of a seat belt over any armrest.
• Wear a shoulder belt under your arm nearest the door.
• Use a belt for more than one person at a time.
• Wear the belts twisted or with a buckle release button facing
downward or inward.
• Let the belt system become damaged by the door or seat.
• Put anything into the opening where the seat belt passes through the
trim panel. (This may jam the retractor or damage the belt.)
Twisted Belt
Do not let the belt twist while it is rewinding: it may cause the
retractor to jam so it will not rewind further. If it is not fully rewound,
the belt cannot be pulled out. Should the belt jam, you may be able to
release it by working the belt in and out until the belt rewinds far
enough to unlock. However, if the belt remains jammed or other parts
of the restraint system do not work properly, have your dealer service
it.
CAUTION: To help reduce the risk of personal injury in collisions or
sudden maneuvers, use the seat belts following these instructions
on their proper use, maintenance, and use with child restraint
systems. This applies to pregnant women. Pregnant women should
use a lap-shoulder belt whenever possible; the lap portion should
continue to be worn low and snug throughout the pregnancy.
Children small enough for child restraints (as indicated on the
label of such restraints), including booster seats, should always be
transported in them.
Children who have outgrown child restraint systems should use
the vehicle’s seat belts.
55702_Sec01_'08 08.2.12 9:43 AM Page 10
1-11
LAP-SHOULDER BELT
1. Adjust the driver’s seat as needed and sit well back and straight up.
(The passenger seat does not adjust.) Grasp the latch plate and:
• Pull the belt as far as it will reach across your lap.
• Hold the latch plate at an angle to the webbing and slide it
further (toward the front of the truck).
• Then pull it slowly across your lap and push it into the buckle
until it clicks. If the retractor locks before the latch plate reaches
the buckle, let the belt retract slightly, then withdraw it slower
than before.
2. To reduce the risk of sliding under the belt during a collision,
position the belt across your lap as low on your hips as possible
and adjust it to a snug fit by pulling the “shoulder” portion upward
through the latch plate.
The lap-shoulder belt is designed to lock during a sudden stop or
impact. At other times it should move freely.
CAUTION: To help reduce the risk of personal injury or death in an
accident, if a child is using the vehicle’s seat belts because the
child has outgrown child restraints, including booster seats, and if
the shoulder belt is on or very close to the child’s face or neck,
move the child toward the center of the seat, away from the
shoulder belts.

3. To unfasten the belt, push the button on the buckle. The belt
should retract when the buckle is unlatched, but hold the latch
plate while the belt is retracting, to keep it from hitting people or
nearby objects. To help prevent damage to the seat belt and
interior trim before closing the door, be sure the belt is fully
retracted and the latch plate is out of the way.

1-13
CENTER LAP BELT
1 . The center seat lap belt has no retractor, but should be positioned,
worn and released as described above. The belt is adjusted to
snug fit by pulling on the free end of the webbing coming from the
latch plate.
2. To lengthen the center seat lap belt, place the latch plate at an
angle to the belt webbing and pull on the latch plate; the belt
should then slide easily through the latch plate adjustment feature.
SEAT BELT INSPECTION
Now and then check that the belts, buckles, latch plates, retractors,
anchorages and guide loops work properly; look for loose parts or
damage (without disassembly) that could keep the restraint system
from doing its job. Have a belt assembly replaced if the webbing has
been cut or otherwise damaged. Replace belts, retractors, and
hardware used in all but a minor collision. Also, restraint systems
should be replaced and anchorages properly repaired if they were in
areas damaged by a collision, whether the belt was in use or not. If
there is any question, replace the belt system. Damage, whether
visible or not, could result in a serious personal injury in the event of
an accident.

CHILD RESTRAINT
Be sure to follow all installation and use instructions that come with
any child restraint system.
Child restraint systems are designed to be secured in vehicle seats
either by the lap belt, or the lap portion of the lap-shoulder belt at that
seating position. The child must also be secured within the restraint by
the means provided by the child restraint manufacturer. If the child or
the child restraint is not properly secured, the child risks personal
injury in the event of a collision.
Using a Lap Belt That Has No Retractor
When securing a child restraint with the center seat lap belt, pull the
excess webbing through the belt’s adjustment feature, then take these
steps:
• Once installed, push and pull the child restraint in all directions to be
sure it is secure. If it comes loose, flip the end of the belt with the
adjustment feature over before rebuckling.
• If the child restraint is still not secure, use the outboard seating
position in the vehicle and contact your dealer and the child restraint
manufacturer for help.
• Secure the child in the restraint in accordance with the child restraint
manufacturer’s instructions.
CAUTION: Children small enough for child restraints (as indicated
on the label of such restraints), including booster seats, should
always be transported in them. Children who have outgrown child
restraint systems should wear seat belts. The lap belt should be
snug and positioned low on the abdomen so that it is below the
top of the hipbone. Otherwise, the belt could intrude into the
child’s abdomen during an accident and cause personal injury.
When a child has grown enough so that the shoulder belt can be
worn, a seating position with a shoulder belt should be chosen
whenever possible. If the shoulder belt is on or very close to the
child’s face or neck, move the child toward the center of the seat,
away from the shoulder belt.
Any unrestrained child could be injured by striking the vehicle’s
interior or by ejection from the vehicle during an accident or
driving maneuver. Never allow a child to be held by another
occupant instead of being properly restrained. If not properly
restrained, the child could strike the vehicle interior or be crushed
by the person holding the child, or by other occupants.

Installation on Outboard Seat
A seat belt locking clip is required for installation of a child restraint
system on the outboard seat of this vehicle. A locking clip may usually
be obtained where child restraints are sold, or by contacting your
dealer for assistance. Make sure the locking clip is identical to the one
shown on page 1-16. Until you have the clip, use the child restraint
system only in the center seat.
CAUTION: To help avoid personal injury or death during a collision
or sudden maneuver, always thread both the lap and shoulder belt
through the locking clip when securing a child restraint on the
outboard seat. If the clip is not used or installed properly, the child
restraint may move or tip over when your vehicle turns or stops
abruptly.
Secure the child restraint with the lap belt portion of the seat belt in
accordance with the restraint manufacturer’s instructions. Then thread
both the lap and shoulder belt portions through the locking clip. Push
and pull the child restraint in all directions to be sure it is secure.
When your child restraint is not installed, remove the locking clip to
permit normal use of the lap-shoulder belt. Keep the locking clip in the
glove box to help prevent its loss.
Child Restraint With Top Strap
CAUTION: We do not recommend using a child restraint that
requires the use of a top strap. There is no appropriate place to
attach a top strap anchor behind the seat in this vehicle.

SEAT BELT EXTENDER
If the vehicle’s seat belt will fasten around you, you should use it.
But if a seat belt isn’t long enough to fasten, your dealer will order you
an extender. When you go in to order it, take the heaviest coat you will
wear, so the extender will be long enough for you. The extender will be
just for you, and just for the seat in your vehicle that you choose. Do
not let someone else use it, and use it only for the seat it is made to fit.
To wear it, just attach it to the regular seat belt.

DIESEL PARTICULATE FILTER (DPF)
The DPF is the system which traps Particulate Matter (PM) in
exhaust gas. This collects PM into the DPF and regenerates the filter
(burns PM) automatically. To prevent DPF failure, take the following
precautions.
CAUTION:
• Exhaust gas from the DPF, muffler, exhaust pipe and tailpipe is
extremely hot when the engine is running, during regeneration
(burning), or immediately after driving.
Nearby flammable materials such as dried grass and wastepaper
may catch fire.
Be very careful not to touch them by accident. You may get
burned.
When you service the vehicle, stop the engine to prevent burns.
• Always use diesel fuel. Use of low quality fuel may adversely
affect the engine parts, and cause failure.
• Use of other than specified fuel may adversely affect the engine
or emission control system and cause failure. Especially for
common rail type engines, always use ultra low sulfur diesel fuel
(15 ppm or less of sulfur content).
• If other than specified diesel fuel is used on a vehicle with DPF,
the vehicle may not conform to specifications.
• Do not modify the DPF or exhaust pipe.
Modification of the direction, length or diameter of the exhaust
pipe will adversely affect the exhaust gas purification system. If
modification is needed according to equipment type, contact
your Isuzu dealer.

NOTICE:
• For engine oil, use low ash engine oil. Use of others than those
designated by Isuzu that support the DPF may shorten the
cleaning intervals of the DPF and may lower fuel efficiency.
• The DPF automatically regenerates when a certain amount of PM
(Particulate Matter) accumulates in the filter. However, this may
not complete depending on driving conditions. In this situation,
the DPF indicator (amber) will come on. Perform manual
regeneration according to the procedure. This is not a system
failure, but is to restore the DPF function.
• The exhaust brake valve is activated while the vehicle is idling in
the DPF regeneration (burning) mode. Sound occurs when the
exhaust brake valve is activated and deactivated. This is not a
failure.
• A small amount of white smoke may be emitted from the exhaust
pipe with Particulate Matter (PM) burned during DPF
regeneration. This is not a failure. Also, do not perform the
emergency regeneration indoors with poor ventilation.
• White smoke may be emitted during the DPF regeneration after
the new vehicle runs for a certain distance.
This is not a failure. White smoke may not necessarily be emitted
when the vehicle is new.
• Because of the exhaust gas purification system, the gas from the
exhaust pipe smells differently from that of conventional diesel
vehicles.
• With long continuous idling, the exhaust brake valve may be
activated to prevent white smoke after a certain period of time.
• Use of low ash oil lengthens the maintenance interval of the DPF.

CAUTION: In a place with poor ventilation, carbon monoxide
poisoning may occur. Starting or warming-up the engine should be
performed in a well-ventilated place. White smoke may be
temporarily emitted due to PM combustion during the DPF manual
regeneration. Do not perform DPF manual regeneration indoors
with poor ventilation.
CAUTION:
• Before starting the engine, make sure that there are no
flammable materials around the vehicle and dried grass does not
wind around the exhaust pipe. Be careful that the hot exhaust
pipe and hot exhaust gas does not catch fire after engine racing,
or engine running at high speed for long periods of time.
• Pay close attention to the heat of the exhaust gas during idling
especially when using the PTO (POWER TAKE-OFF) or
afterburning on the vehicle equipped with the DPF.
CAUTION: Always use diesel fuel.
Use of low quality fuel may adversely affect the engine parts, and
cause failure.
Use of other than specified fuel may adversely affect the engine
or emission control system and cause failure. Especially for the
common rail type engine, always use ultra low sulfur diesel fuel (15
ppm or less of sulfur content).
If other than specified diesel fuel is used on the vehicle with the
DPF, the vehicle may not conform to specifications.
BEFORE DRIVING
Use the specified fuel (ultra low sulfur diesel fuel only)
Do not keep the engine running indoors
Be careful with flammable materials

SECTION 2
STARTING AND OPERATING
Engine Exhaust Gas Caution
(Carbon Monoxide)
CAUTION: Do not breathe exhaust gas because it contains carbon
monoxide, which by itself has no color or odor. Carbon monoxide is
a dangerous gas. It can cause unconsciousness and can be lethal.
If at any time you think exhaust fumes are entering the cab, have
the cause determined and corrected as soon as possible. If you must
drive under these conditions, drive only with all windows fully open.
Prevent carbon monoxide from entering the cab. The best way is
to keep the engine exhaust system, cab and cab ventilation system
properly maintained.
We recommend that the exhaust system and cab be inspected by
a competent technician:
•
Each time the vehicle has an oil change.
•
Whenever a change is noticed in the sound of the exhaust system.
•
Whenever the exhaust system, underbody or cab is damaged or
becomes corroded.
See “Maintenance Schedule” in Section 5 of this manual for parts
requiring inspection.
To allow proper operation of your vehicle’s ventilation system, keep
the air inlet grille clear of snow, leaves or other obstructions at all times.
Do not park with the engine running or idle this vehicle for more than
10 minutes with the ventilation system control switch in the “OFF”
position. Even with the ventilation system on, running the engine while
parked or stopped for longer periods of time is not recommended. Entry
of carbon monoxide into the cab is possible with a poorly repaired,
damaged, or corroded exhaust system or cab.
Do not run the engine in confined areas (such as garages or next to a
building) any more than needed to move the vehicle. When the vehicle
has to be stopped in an unconfined area with the engine running for any
more than a few minutes, take the following steps:
A. Adjust the heating or cooling system to force outside air into
the cab. With temperature and select levers in any position:
•
Set the air source lever to the fresh air position.
•
Set the fan blower to the “3” or “4” position.
•
See “Heating and Ventilation System Controls” later in this
section of the manual.
B. Keep the exhaust tailpipe area clear of snow and other material
to help reduce the buildup of exhaust gases under the vehicle.
This is particularly important when parked in blizzard conditions.

NEW VEHICLE BREAK-IN
Good vehicle care begins with proper break-in. While every new
vehicle goes through rigid factory and dealer inspection and tests
before delivery, the care you give your vehicle during the initial breakin period can pay off in longer life, better performance and more
economical operation. Follow the recommendations listed below:
•
Warm up the engine by driving easily for the first few minutes before
placing it under load.
•
Keep speeds below 50 MPH (80 km/h) for the first 500 miles (800
kilometers).
•
Do not drive for extended periods at any one constant speed, either
fast or slow, during the first 500 miles (800 kilometers).
•
Use the lowest gear ratio available when starting a loaded vehicle
and when climbing slopes to avoid lugging the engine.
•
Use the correct gear to maintain the desired road speed without
lugging the engine.
•
Avoid racing the engine, full-throttle starts and aggressive application
of brakes when stopping.
•
Keep tires properly inflated for the load carried.
•
Check lubricant levels in the engine and transmission frequently (at
least weekly).
MECHANICAL DRIVESHAFT BRAKE
BURNISH PROCEDURE
It is recommended that the driveshaft mounted parking brake be
burnished as part of the new vehicle break-in procedure. Increased
parking brake performance will result when the parking brake is
burnished according as specified below:
•
Make 10 moderate stops, using the hand brake, from 10 MPH (16
km/h) while spacing the stops a minimum of 2.5 miles (4 km) apart.
•
Operate the vehicle at 20 MPH (32 km/h) between stops.
