0B-12 GENERAL INFORMATIONOWNER INSPECTIONS AND SERVICES
WHILE OPERATING THE VEHICLE Horn Operation Blow the horn occasionally to make sure it works. Check all the button locations. Brake System Operation Be alert for abnormal sounds, increased brake pedal travel or repeated puling to one side when braking. Also, if the brake warning light goes on, or flashes, something may be wrong with part of the brake system. Exhaust System Operation Be alert to any changes in the sound of the system or the smell of the fumes. These are signs that the system may be leaking or overheating. Have the system
inspected and repaired immediately. Tires, Wheels and Alignment Operation Be alert to any vibration of the steering wheel or the seats at normal highway speeds. This may mean a wheelneeds to be balanced. Also, a pull right or left on a straight, level road may show the need for a tire pressure adjustment or a wheel alignment. Steering System Operation Be alert to changes in the steering action. An inspection is needed when the steering wheel is hard to turn or
has too much free play, or is unusual sounds are noticedwhen turning or parking. Headlight Aim
Take note of the light pattern occasionally. Adjust the headlights if the beams seem improperly aimed.
AT EACH FUEL FILL A fluid loss in any (except windshield washer) system may indicate a problem. Have the system inspected and
repaired immediately. Engine Oil Level
Check the oil level and add oil if necessary. The best time to check the engine oil level is when the oil is warm.
1. After stopping the engine, wait a few minutes for the oil to drain back to the oil pan.
2. Pull out the oil level indicator (dip stick).
3. Wipe it clean, and push the oil level indicator back down all the way.
4. Pull out the oil level indicator and look at the oil level on it. 5. Add oil, if needed, to keep the oil level above the
lower mark. Avoid overfilling the engine, since this may cause engine damage.
6. Push the indicator all the way back down into the engine after taking the reading.
If you check the oil level when the oil is cold, do not runthe engine first. The cold oil will not drain back to the pan fast enough to give a true oil level reading. Engine Coolant Level and Condition Check the coolant level in the coolant reservoir tank
and add coolant if necessary. Inspect the coolant. Replace dirty or rusty coolant.
Windshield Washer Fluid Level
Check the washer fluid level in the reservoir. Add fluid if
necessary.
AT LEAST TWICE A MONTH Tire And Wheel Inspection and Pressure Check Check the tire for abnormal wear or damage. Also check for damaged wheels. Check the tire pressure when the tires are cold ( check the spare also, unless it is astowaway). Maintain the recommended pressures. Refer
to “Tire and Wheel” is in section 0B.
AT LEAST MONTHLY Light Operation Check the operation of the license plate light, the headlights (including the high beams), the parking lights,the fog lights, the taillight, the brake lights, the turn
signals, the backup lights and the hazard warning flasher. Fluid Leak Check Periodically inspect the surface beneath the vehicle for
water, oil, fuel or other fluids, after the vehicle has been
parked for a while. Water dripping from the air conditioning system after use is normal. If you notice fuel leaks or fumes, find the cause and correct it at once.
AT LEAST TWICE A YEAR Power Steering System Reservoir Level Check the power steering fluid level. Keep the power steering fluid at the proper level. Refer to Section 6A,
Power Steering System. Brake Master Cylinder Reservoir Level Check the fluid and keep it at the proper level. A low fluid level can indicate worn disc brake pads which mayneed to be serviced. Check the breather hole in the reservoir cover to be free from dirt and check for an open passage.

16. Remove the power steering pump lines.Notice Completely drain the fluid.
17. Disconnect the fuel feed line with prefilter from the feed pump on injection pump.
18. Vehicle with automatic transmission. Remove the hydraulic lines (19, 20) from oil cooler (2).
19. Disconnect the engine harness.
20. Disconnect the preheating time relay cable.

27. Disconnect the preheating time relay sensor plug.
28. Disconnect the coolant temperature sensor plug.
29. Disconnect the accelerator cable from the control linkage.Installation Notice
Tightening Torque 8 - 18 Nm
30. Loosen the connection of control pressure cable (an arrow) used in auto transmission.

Replacement Procedure
1. Drill a hole into the ring gear (1) (arrow) and snap
with a chisel.
2. Thoroughly clean the collar surfaces of ring gear.
3. Measure diameter (a) of centering collar.
Notice If out of standard, replace the flywheel.
4. Heat up the new ring gear up to 220 °C by using a
heating device. Notice Use temperature measuring chalk.
5. Install the new ring gear (1) onto the flywheel by using a drift.

1. Preheating time - control relay.Control relay functions as followings :
Switching of preheating current.
Indication of preheating finish.
Control of preheating sequence.
Indication of fault.
2. Coolant temperature sensor. Coolant temperature sensor senses coolant ’s temperature
and signals it to the preheating relay continuously.
3. Glow plug The glow plug parts are housing with M12 ´ 1.25 thread
and heating pin in housing. It is connected in a parallel circuit
with the specified voltage of 11.5V. The heating element has a heating coil and a control coil and they are connected in series.
1. Control Coil 2. Heater Coil
4. Current and temperature of glow plug Current of glow plug While the preheating system operates, current of about
30A flows in each glow plug and temperature of heating coil rises very fast.
Due to the rise of temperature, the resistance of control
coil increases therefore the current is controlled to
about 8~15A and that protects the glow plug from over-
heating.
Temperature of glow plug The temperature of the glow plug reaches up to 900 °C
after about 9 seconds and up to 1,050 °C after 30
seconds.

Preheating System Operation
1. Preheating before start.Preheating time is different by coolant temperature and it is on until the glow indicator light goes off.
2. Preheating after start. Preheating continues for max. 60 seconds to rise in characteristic of warming-up on engine after starting too.
3. Monitoring on glow plug. Glow plugs are monitored by low current by the microprocessor in control relay respectively while running theengine. If glow indicator comes on after starting for about one minute,
it indicates on or several plugs are faulty.
Possible Cause
- One or several glow are faulty
Problem
Glow indicator does not come on in preheating time and comes on after starting the engine. Glow indicator does not come on while preheating and after starting engine. Glow indicator does not come on and engine
’s
starting is difficult or does not start at all. Glow indicator comes on after starting for about one minute.1 2 3 4 - Faulty glow indicator
- Faulty circuit of glow indicator
- Faulty control relay
- Circuits short in one or several glow plugs
- Faulty preheating circuits
- Faulty control relay
- One or several glow plugs are faulty
