FUEL SUPPLY SYSTEM

According to input signals from various sensors, engine ECU calculates driver’s demand (position of the accelerator
pedal) and then controls overall operating performance of engine and vehicle on that time.

ECU receives signals from sensors via data line and then performs effective engine air-fuel ratio controls based on those
signals. Engine speed is measured by crankshaft speed (position) sensor and camshaft speed (position) sensor deter-
mines injection order and ECU detects driver’s pedal position (driver’s demand) through electrical signal that is gener-
ated by variable resistance changes in accelerator pedal sensor. Air flow (hot film) sensor detects intake air volume and
sends the signals to ECU. Especially, the engine ECU controls the air-fuel ratio by recognizing instant air volume
changes from air flow sensor to decrease the emissions (EGR valve control). Furthermore, ECU uses signals from
coolant temperature sensor and air temperature sensor, booster pressure sensor and barometric sensor as compensa-
tion signal to respond to injection starting, pilot injection set values, various operations and variables.

MAINTENANCE AND LUBRICATION

Normal Vehicle Use

The maintenance instructions contained in the maintenance
schedule are based on the assumption that the vehicle
will be used for the following reasons:

• To carry passengers and cargo within the limitation of

the tire inflation prassure. Refer to “Wheels and Tire”
in section 4H.

• To be driven on reasonable road surfaces and within

legal operating limits.

Explanation of Scheduled
Maintenance Services

The services listed in the maintenance schedule are fur-
ther explained below. When the following maintenance
services are performed, make sure all the parts are re-
placed and all the necessary repairs are done before driv-
ing the vehicle. Always use the proper fluid and lubricants.

Engine Oil and Oil Filter Change

Always use above the API SH grade or recommended en-
gine oil.

Engine Oil Viscosity

Engine oil viscosity (thickness) has an effect on fuel
economy and cold weather operation. Lower viscosity en-
gine oils can provide better fuel economy and cold weather
performance; however, higher temperature weather condi-
tions require higher viscosity engine oils for satisfactory
lubrication. Using oils of any viscosity other than those
viscosities recommended could result in engine damage.

Cooling System Service

Drain, flush and refill the system with new coolant. Refer
to “Recommended Fluids And Lubricants” in this section.

Air Cleaner Element Replacement

Clean the air cleaner element every.

• Gasoline Engine : 15,000 km (10,000 miles)

• Diesel Engine : 10,000 km (6,000 miles)

Replace the air cleaner element every.

• Gasoline Engine : 60,000 km (36,000 miles)

• Diesel Engine : 30,000 km (18,000 miles)

Replace the air cleaner more often under dusty conditions.

MAINTENANCE AND REPAIR

Fuel Filter Replacement

Replace the engine fuel filter every.

• Gasoline Engine : 60,000 km (36,000 miles)

• Diesel Engine : 30,000 km (18,000 miles)

Spark Plug Replacement

Replace spark plugs with same type.

• Type : BOSCH : F8DC4

BERU : 14F-8DU4
Champion : C11YCC

• Gap : 0.8 ± 0.1 mm

Spark Plug Wire Replacement

Clean wires and inspect them for burns, cracks or other
damage. Check the wire boot fit at the Distributor and at
the spark plugs. Replace the wires as needed.

Brake System Service

Check the disc brake pads or the drum brake linings. Check
the pad and the lining thickness carefully.

Tire and Wheel Inspection and Rotation

Check the tires for abnormal wear or damage. To equalize
wear and obtain maximum tire life, rotate the tires. If ir-
regular or premature wear exists, check the wheel align-
ment and check for damaged wheels. While the tires and
wheels are removed, inspect the brakes.

GUIDELINES FOR SERVICE WORK SAFETY

General

Notice

Notice means precautions on tool/device or part
damages or personal injuries that can occur during
service works.

To maintain and operate the vehicle under optimum state
by performing safe service works, the service works should
be done by following correct methods and procedures.

Accordingly, the purpose of this manual is to prevent dif-
ferences that can be caused by personal working method,
skill, ways and service procedures and to allow prompt/
correct service works.

Note, Notice

While using this manual, there are a lot of Note or Notice
having below meaning.

Note

Note means detailed description of supplementary
information on work procedure or skill.

However, above references and cautions cannot be inclu-
sive measures, so should have habits of taking concerns
and cautions based on common senses.

Cautions on Inspection/Service

Notice

During service works, be sure to observe below general
items for your safety.

•

For service works, be sure to disconnect battery
negative (-) terminal if not starting and inspection.

•

While inspecting vehicle and replacing various
consumable parts, be sure to take caution not to
damage vehicle and injure people.

•

Engine and transmission may be hot enough to
burn you. So inspect related locations when they
cooled down enough.

•

If engine is running, keep your clothing, tools, hair
and hands away from moving parts.

•

Even when the ignition key is turned off and
positioned to LOCK, electrical fan can be operated
while working on near around electrical fan or
radiator grille if air conditioner or coolant
temperature rises.

•

Every oil can cause skin trouble. Immediately wash
out with soap if contacted.

•

Painted surface of the body can be damaged if
spilled over with oil or anti-freeze.

•

Never go under vehicle if supported only with jack.

•

Never near the battery and fuel related system to
flames that can cause fire like cigarette.

•

Never disconnect or connect battery terminal or other
electrical equipment if ignition key is turned on.

•

While connecting the battery terminals, be cautious
of polarities (+, –) not to be confused.

•

There are high voltage and currency on the battery
and vehicle wires. So there can be fire if short-
circuited.

•

Do not park while running the engine in an
enclosed area like garage. There can be toxication
with CO, so make sufficient ventilation.

•

The electrical fan works electrically. So the fan can
be operated unexpectedly during working causing
injuries if the ignition key is not in LOCK position.
Be sure to check whether ignition key is in LOCK
position before work.

•

Be careful not to touch hot components like
catalytic converter, muffler and exhaust pipe when
the engine is running or just stopped. They may
burn you badly.
