Use the Specified Fuels
All the time only use lower amount of sulphured diesel fuel (50 ppm amount or less of sulphur)
or with super low sulphured dieselfuel (10ppm amount or lesssulphur). The useof poor quality
diesel fuel, any addition of an additional substance such as a fuel cleaner in the tank with
gasoline, kerosene or an alcohol-based fuel or a mixture of diesel fuels can damage the fuel
filter and cause injectors to have a lubrication problem onthe fuel lubricated components. Apart
from all, this could damage the exhaust emission system of the engine and DPD, which could
cause the malfunction of engine-related systems. Drain all the fuel from the system in case
where an unsuitable fuel is accidently filled in. If the caution is not applied, when the engine
starts it could result in a fire or permanent damage. If a low sulphur or super sulphur diesel fuel
is used in the vehicle with DPD, any occurring accidents will be considered outside of the scope
of warranty.
Diesel fuel specifications vary by season and region.
Refuelling at Fuel Stations
When refuelling your vehicle;
Stop the engine, close the doors and windows of the vehicle.
Do not approach the vehicle with cigarettes and other flammable substances.
Before opening the fuel filler cap, touch something metal to discharge static electricity from
your body. If a static charge has accumulated in your body while refuelling, a spark
generated by discharging can ignite fuel and cause burning.
When refuelling the vehicle, fully insert the fuel nozzle into the filler neck. It is dangerous to
try to fill more fuel by pumping fuel with a partially pulled out nozzle. Because the automatic
stop mechanism may not work thus may cause fuel to overflow. All stages of the refuelling
procedure (from opening the fuel filler cap to the completion of filling and closing the fuel
filler cap) must be performed by the same person. Others may carry static electricity. Do
not allow others to approach the fuel tank. The person refuelling should not return to their
seat in the cabin in the middle of the procedure. They may collect static electricity by doing
that.
Do not use any fuel filler cap that is not an original Isuzu item.
Follow all the warnings at filling stations.

8
Do not keep fuel cans and spray cans in the cabin.
Keeping a fuel can and spray can in the cabin is extremely
dangerous. Ignition or cracking of a container such as these
items may cause a fire or explosion.
Usage of Curtains
Keep the curtains in a way not to interfere with your vision and driving.
Keep the Surrounding of the Driver’s Seat Clean and Tidy
It is extremely dangerous to have empty boxes rolling on
the floor, empty bottles and other items. Because these
items can get stuck under the brake pedal and prevent
the usage of brake pedal. It is also very important that
the floor mats are properly placed for suitable pedal use.
Improperly placed floor mats will prevent the pedals from
moving smoothly.
Do not use the front panel space or the top of that space as a place to put rolling items that
could interfere with your drive.
Correct Driving Position
Before driving, be sure to set the seat, steering wheel and mirrors are in the correct driving
position for you. Make sure that the seat is firmly in place by moving forward and backward
while seated, then fasten your seatbelt.
Seat Adjustment;
Adjusting the seat for the correct driving position is the most important part of safe driving.
Seat adjustment recommendations
Adjust the steering wheel in a way that your elbows are slightly bent so that you can
easily turn the wheel whenever you want.
Always position the backrest in a way that it touches your shoulders.
Make sure you can press each pedal.

9
Adjusting the steering wheel position;
You can adjust the steering wheel position in up and down and back andforth directions. When
you have adjusted the steering wheel, try pulling it up and down to check if its securely locked
before driving.
Fastening the seatbelts;
Make sure you fasten your seat belts
2.DRIVING
Check the Area Around the Vehicle Before Starting the Engine
Before moving, carry out a thoroughly done safety check, make sure that there are no
children or any obstacles around the vehicle.
Make sure that there are no flammable substances under or around the vehicle before
starting the engine.
Pay Attention to Exhaust Emissions
Exhaust emissions contain carbon monoxide which is colourless, odourless and toxic.
Inhaling exhaust emissions may cause carbon monoxide poisoning.
Do not leave the engine running for some time in a poorly ventilated place. It is particularly
dangerous to run the engine in a garage or other confined space where it can easily fill the
space with exhaust gases which can cause carbon monoxide poisoning.
Check the exhaust pipe time to time. If you see any damage (for example a damaged
connection piece with a wear or a hole or crack), visit the nearest Isuzu service for control
and maintenance. It will be dangerous to continue driving without repairing the damage.
Because exhaust gases can enter the cabin thus cause carbon monoxide poisoning.
Seatbelt buckle warnings.
Place the seatbelts on your hip level.
Wear the shoulder strap over the shoulder. (Make sure
that it does not touch your face)
Make sure that the seatbelts are not
twisted when you fasten.

10
If exhaust gases get inside the cabin, open all windows completely and switch AC’s
interior/exterior air selector mode on exterior. Make sure you bring your vehicle to the nearest
Isuzu service for control and maintenance. It will be dangerous to continue driving without
repairing the damage. Because exhaust gases can enter the cabin thus cause carbon
monoxide poisoning.
Starting the Engine
Make sure the handbrake is pulled safely. Make sure
to check that the gear selector is in the “N” position
before starting the engine then hold the clutch pedal
fully pressed.
Engine Heating
When the engine coolant temperature indicator hand starts to move, it shows that the engine
is sufficiently warm.
Do not increase the engine speed or accelerate the engine immediately before the engine
has heated sufficiently. A malfunction occurs if either parts do not reach and cannot be
lubricated enough.
The exhaust pipe overheats when the engine is idling. Make surethat there is no flammable
material (For example dry grass, rubbish paper or old tires) near the exhaust pipe before
heating the engine.
Do Not Start the Engine in the Garage
Running the engine in an insufficiently ventilated place may lead to carbon monoxide
poisoning. Choose a well-ventilated place to start and heat the engine. Also do not perform
manual DPD regeneration on a model with a diesel particle dispenser (DPD). DPD
regeneration process emits white smoke during combustion of particulate matter (PM).
Pulling the Handbrake
Start gently in 2nd or lower gear. (1St gear on hills)
Starting on a high gear, too quickly or clutching too long when starting will damage the clutch.

11
Downshifting
Downshifting is done for two reasons:
- For engine braking on steep slopes and/or long downhill slopes
- Quick solutions and economical easiness while driving uphill
and downshifting
Over-speeding the engine may cause engine failure. Do not over-speed the engine
during downshifting.
Uphill driving; perform downshifting to avoid heavy engine load.
Downhill driving; you should use the gear you used while diving uphill. Drive the vehicle at
such speed that it does not cause the engine to over-speed thus make the tachometer enter
the red zone.
Drive at a speed that will not cause the tachometer to not to show that it has entered the
red zone. The green zone is a good router for economic driving.
Do Not Stop the Engine While Driving
Do not turn the ignition key to any position other than “ON” (OPEN) while driving.
Stopping the engine while driving can be quite dangerous because;
Brakes do not work properly. Using the clutch pedal and the steering wheel will be
more compelling and stiffer. It may also damage the engine.
Operation of the hydraulic steering wheel will make turning the wheel difficult.
The warning lights and other electrical circuits will stop working completely.
Steering wheel can be locked.
Do Not Continue Driving with Flat Tires
If you feel something unusual in a tire while driving, stop immediately in a safe place. If you
continue driving with a flat tire, excessive force may be applied to the wheel studs thus may
cause the bolts to break and tire to fall off.
If the Bottom of the Vehicle Gets a Hard Blow
If the bottom of the vehicle receives a hard blow, stop in a safe place and check if there is any
brake fluid leak, fuel leak and component malfunction. If any part of the vehicle fails or breaks,
have the vehicle inspected and repaired immediately by the nearest Isuzu service.

12
Economic Driving
Driving at very high engine speed, driving at low engine speed making sounds at the engine,
when the exhaust brake is always engaged, when exhaust brake is always open and adjusting
to the speed are often result in low levels of fuel economy. Drive at a constant speed as much
as possible. While speeding up, accelerate gently, slowly and shift the gear beforehand.
Heating the engine longer than necessary and using the engine on high speed is wasting fuel.
Driving with an overloaded vehicle also means wasting fuel. Check the tire pressures
frequently.
Safe Driving
1.Cautions While Driving
Concentrate on safely driving by following traffic signs and traffic lights to all legally set
speed limits.
Do not turn the ignition key to any position other than “ON” (OPEN) while driving. Operation
of the hydraulic steering wheel will make turning the wheel difficult. Also, brakes will not
work properly and will endanger you.
If you notice any abnormal sound, smell or vibration from any part of the vehicle, stop right
away in a safe place and check immediately.
If a warning lamp comes on or an audible signal comes on while driving, stop the vehicle in
a safe place immediately and check.
Do not place your foot on the clutch pedal when you are not using the shift lever. Doing so
may cause early abrasion of the clutch.
Slow down whenapproaching a turning point. Pressing onthe brakes orturning thesteering
wheel sharply when turning a corner may cause wheels to slip and the vehicle to fall.
Do not put your hand on the gear level unless you are changing the gears while driving.
Doing so may cause the transmission to malfunction.
Avoid rubbing the sidewall of the tires with paving stones or avoid driving over pits and
ledges on the road surface. You may damage the tires and cause the tires to explode or
come down.
Usage of Brakes
The stopping distance of the vehicle consists of a response distance (from the point where the
driver senses danger to the point when the brakes operate) and a braking distance (from where
the brakes began operating) to the point when the vehicle stops. Take the stopping distance
in consideration while driving. Maintain a speed and travel distance that allows you to stop
safely even if there is a dangerous situation.
If the Windshield is Misted
Use the heater to blow warm air to the windshield or dehumidify the cabinet using the air
conditioner and turn the air ventilator to “ ” or “ ” option.
Put interior/exterior option on exterior. Also use an anti-mist spray.

13
Night-time Vision
If there is an oil layer on the windshield, the approaching traffic lights may be reflected in many
directions, making it difficult for you to see your way. Use a window cleaner to clean the
windshield and wiper blades.
Night Drive
Driving at night is more dangerous than driving at daytime. Because the field of vision is
narrower. Keep your speed low and maintain a safe amount of distance while driving.
Driving in Foggy Weather
Switch on the fog lights and drive slowly under the guidance of the central road line. It is
dangerous to follow only the lights of the vehicle ahead. Because it can mislead the driver.
Drive carefully.
Driving on Snowy or Icy Roads
Never accelerate suddenly on slippery roads, do not brake hard, do not speed up
quickly or take sharp turns with the steering wheel.
There is a danger of reduced grip and increased braking distance between tires and road
surface. The danger of icy road surfaces are particularly high in dark places on bridges and
in puddles. Keep your speed low on snow or frozen road surfaces and remember to use tire
chains or snow tires.
Driving on Surfaces in Bad Condition (Muddy or Sandy roads)
If the vehicle gets stuck in the sludge, pressing the accelerator pedal too far will simply push
the sludge deeper and make it more difficult to remove. In order to gain traction, put stones,
tree branches, or a cover under the tires or drive the vehicle back and forth to use the speed
of the vehicle.
Using the tire chains is an effective way to prevent being stuck if you have to drive deep in the
mug.
Avoid sudden braking when driving on a muddy or sandy road, avoid acceleration and turn
steering wheels and taking sudden turns. Such movements can cause the vehicle to sink and
will result in moving the vehicle impossible.
After driving in deep mud, the mud sticking on the vehicle can damage the steering brakes and
the power connection mechanisms. Wash the vehicle and remove all sludge and other
coatings.
Cleaning snow from window and from bottom of the vehicle
Use a plastic scraper to clean snowy and frostedglass surfaces to maintainadequate visibility.
By using a plastic rubber scraper, you can clean the snowy and frosted parts. This time, check
is the wiper blades are frozen on the windshield. Also look under the vehicle and remove any
ice particles stuck under it. Be careful not to damage the vehicle.

14
2. Be Careful While Parking, Parking in
Cold Weather
Do not use the handbrakes. If you pull the handbrake, the cables and brake pads may freeze
which makes it impossible to lower handbrakes down again. Park the vehicle in gear.
Do not forget to put wedges against tires. If possible, park the car in garage to prevent freezing
of parts and facilitate starting the engine.
3.Winter Tires
Use winter tires that are of the same size as standard tires. The tread grooves of a winter tire
have reached the wear limit when opened to half of the tire depth. During abrasion period, the
flats indicating that the condition of the tire which can no longer perform well on the snow
become visible in the cavities. Change the tires with new ones.
Usage of the Tire Chains
Before winter comes, make preparations for the use of tire chains by adjusting the length and
by checking for any damage.
Tire chains cannot be attached to the front wheels. Attach the appropriate tire chains to the
tires on the back.
Putting on the tire chains.
1. Make sure that the tire chain is not twisted and place it on the tire with bent edges faces
outwards (the parts where it touches the surface).
2. Pull the both sides of the tire chain as far possible. Assemble the inner hooks first and
then the outer hooks.
3. Fasten the excess part of the chain with the cable to prevent it from striking the
vehicle’s body part or brake pipes.
4. Hook the lashing rings on the chain strap (lashing rings outwards) with the lashing rings
around the strap.
5. After installing the tire chains and driving for a while, check that the chains are loose or
untied.

15
Removal of tire chains
1. Remove all cables and chain bands, open the outer hooks and finally the inner hooks.
2. Move the vehicle and remove the tire chain.
3.STOPPING AND PARKING
Select a location where stopping and parking is prohibited and the vehicle is not obstructing
traffic. Pull the handbrake.
Remove all the dirt from the headlight lenses and reflectors so that the vehicle can be seen
by other vehicles.
Do not pull the handbrake until the vehicle has come to a complete stop, except in case of
an emergency. Pulling the handbrake before the vehicle stops may cause malfunctions.
If the vehicle is to be parked on a slope, apply additional measures after pulling the
handbrake and chock the wheels or leave the vehicle in gear. Leave the steering wheel in
a direction where it can hit an obstacle and stop in case of vehicle moving.
Keep the Flammable Materials Away from the Vehicle
The exhaust pipe is extremely hot immediately after driving. Before parking, make sure that
there are no flammable substances around (for example dry grass, paper waste, oil or old
tires). Be extra careful while parking in a garage.
• Observe exhaust gas warning when operating engine on idle. Pay extra attention when
regenerating the diesel particle dispensator DPD in case of engine idling (If your vehicle is
equipped with DPD).
Stopping and Parking the Vehicle with the Engine Running
Put the gear shift level on “N” and pull the handbrake. If you do not follow these steps, any
unwanted pressure on the accelerator pedal may cause an accident.
In diesel particle dispensator (DPD) model, the engine will start the renewal automatically
in DPD when the vehicle is stopped and when the engine is running. Make sure that there
are no flammable material near the muffler DPD and the exhaust pipe to prevent a fire.

16
Exiting the Vehicle
Make sure that you pull the handbrake, stop the engine and lock the doors when you exit
the vehicle. Do not leave your valuable items in places where they can be seen.
If you are driving with a child, don’t leave them alone in the vehicle. A child can play with
the equipment in the vehicle, which can result in an accident. (For example, the vehicle may
move or a fire may start) Also, the interior cabin can become dangerously hot.
Do not leave a lighter or glasses in the vehicle. If the temperature rises dangerously in the
cabin, the lighter could explode and any plastic glasses can get deformed.
4. SAFETY CONDITION
When the Engine Coolant is Hot
Do not loosen or remove the radiator cap when the engine coolant is hot.
When the Muffler and Exhaust Pipe are Hot
The diesel particle dispensator (DPD), muffler and exhaust pipe are extremely hot when the
engine is running and when right after a drive. Be careful not to accidentally touch them when
working near them (for example tipping the container or operating an intermediate part).
Do not install accessories on the windshield or windows
Do not install decorative films or other accessories on the windshield or windows. Any plastic
glass suction cups used to attach accessories can also cause fire or other accidents such as
windows.
Use of the Jack
Make sure you lift the vehicle with a jack on from a hard levelled surface.
Adjust the jack in the correct position. Pull the handbrake first then chock the wheels.
When one of the rear wheels is jacked up, the parking brake has no effect. It may be
dangerous not to chock the wheels in the right places before lifting because the vehicle
may move.
Do not look under or enter the vehicle when its jacked up.
5. PREVENTION OF MALFUNCTIONS
Do not leave the steering wheel fully turned for a long time
If you leave the steering wheel full turned for a long time, oil pumping in the hydraulic steering
will overheat. This may lead to hydraulic steering wheel damage, hydraulic steering wheel unit
damage and hydraulic steering wheel air way damage which are the results of insufficient
lubrication and disruption of sealing ring. In result, it will be very difficult to turn the steering
wheel and this may lead to fire or other incidents to occur.
