CHANGING THE OIL AND FILTER (DIESEL ENGINE)
The engine oil and filter should be changed at
those intervals specified in the maintenance schedule in Section 5. If the car is being drivenin severe conditions, more frequent oil and filterchanges are required.
The procedure for changing the oil and filter is
as follows:
1. Park the car on level ground and set the parking brake. Start the engine and let it warm up until the needle on the coolanttemperature gauge moves above the lowestmark. Turn the engine off and place the gearselector lever in "P" (automatic) or reversegear (manual transaxle).
2. Open the hood and remove the engine oil filler cap. 3. Slide underneath the car and loosen the oil
pan drain plug by turning it counterclockwiseoil pan with a wrench of the proper size. Besure that a drain pan is in position to catch theoil as it drains out, then remove the drain plug.
WARNING: Be very careful when draining the engine oil
as it may be hot enough to burn you!
4. When the oil has stopped draining, replace the drain plug using a new washer and retighten by turning it clockwise. Oil pan drain plug tightening torque: 3.5 ~ 4.5 kgf.m
6. Install a new oil filter in accordance with the
instructions on the carton or on the filter itself. Do not over-tighten. Tightening torque : 1.2~1.6 kgf.mBe sure that the mounting surface on the engine is clean and that the old gasket isremoved completely. Lubricate the new gas-ket on the filter with clean engine oil beforeinstallation.
7. Refill the crankcase with the recommended engine oil. Refer to the specification in chap-ter 9 for engine oil capacity.
8. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
NOTE: Always dispose of used engine oil in an
environmentally acceptable manner. It is sug- gested that it be placed in a sealed containerand taken to a service station for maybereclaimation. Do not pour the oil on theground or put it in with the household trash.
WARNING: Used motor oil may cause irritation or can-
cer of the skin if left in contact with the skin for prolonged periods of time. Wash yourhands thoroughly with soap and warm wa-ter as soon as possible after handling usedoil. 5. Loosen the oil filter drain plug by turning it
counterclockwise with a wrench of the propersize and drain out some oil in the oil filter. Be surethat a drain pan is in position to catch the oil.

4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This relieves any pressure remaining in the cool-ing system. And remove the radiator cap bypushing down and turning counterclockwise. Now fill the radiator with clean demineralized or distilled water. Continue to add clean deminer-alized or distilled water in small quantities untilthe fluid level stays up in the radiator neck.

REPLACING THE SPARK PLUGS The spark plugs should be changed at theintervals specified in the vehicle maintenancesschedule in Section 5 or whenever engine per-formance indicates they should be changed.Symptoms that suggest poor spark plug perfor-mance include engine misfiring under load, lossof fuel economy, poor acceleration, etc. Whenspark plugs are replaced, always use sparkplugs recommended by Hyundai. The use ofother spark plugs can result in loss of perfor-mance, radio interference or engine damage. NOTE: When replacing the spark plugs, genuine Hyundai replacement parts are recom-mended. Recommended Spark Plugs:
SSA6060A
Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)
G050D01FC
5. Start the engine, top off the radiator with
water and then add engine coolant to the reservoir until the level is between "LOW"and "FULL".
6. Replace the radiator and reservoir caps and check to be sure the drain cocks are fullyclosed and not leaking.
WARNING: The cooling fan is controlled by engine cool- ant temperature and may sometimes oper-ate even when the engine is not running.Use extreme caution when working near theblades of the cooling fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition.

CHECKING AND REPLACING FUSES Replacing a Fusible Link
A fusible link will melt if the electrical circuits
from the battery are ever overloaded, thus pre- venting damage to the entire wiring harness.(This could be caused by a short in the systemdrawing too much current.) If this ever happens,have a Hyundai dealer determine the cause,repair the system and replace the fusible link.The fusible links are located in a fuse box foreasy inspection.
CAUTION: When replacing a fusible link, never use
anything but a new fusible link with the same or lower amperage rating. Never use apiece of wire or a higher-rated fusible link.This could result in serious damage andcreate a fire hazard.

Replacing Accessory Fuse The fuse box for the lights and other electrical accessories will be found in the backside of multibox located in the left side of driver. Inside the boxyou will find a list showing the circuits protectedby each fuse. If any of your car’s lights or other electrical
accessories stop working, a blown fuse couldbe the reason. If the fuse has burned out, youwill see that the metal strip inside the fuse hasburned through. If you suspect a blown fuse,follow this procedure:
1. Turn off the ignition and all other switches.
2. Open the fuse box and examine each fuse. Remove each fuse by pulling it toward you (a small "fuse puller" tool is contained in thefuse box to simplify this operation).
3. Be sure to check all other fuses even if you find one that appears to have burned out.

EMISSION CONTROL SYSTEMS 7-1
7. EMISSION CON-TROL SYSTEMS
H010A01A-GAT
EMISSION CONTROL SYSTEMS (If Installed)
Your Hyundai is equipped with an emission
control system to meet all requirements of the Emission prohibition rules of your province. There are three emission control systems which
are as follows.
(1) Crankcase emission control system (2) Evaporative emission control system(3) Exhaust emission control system In order to assure the proper function of the
emission control systems, it is recommended that you have your car inspected and main-tained by an authorized Hyundai dealer in ac-cordance with the maintenance schedule in thismanual. H010D01A-AAT
3. Exhaust Emission Control System
The Exhaust Emission Control System is a
highly effective system which controls exhaustemissions while maintaining good vehicle per-formance.
H010C01E-GAT
2. Evaporative Emission Control
System
The Evaporative Emission Control System is
designed to prevent fuel vapors from escapinginto the atmosphere. Canister
While the engine is inoperative, fuel vapors
generated inside the fuel tank are absorbed and stored in the canister. When the engine isrunning, the fuel vapors absorbed in the canis-ter are drawn into the induction system through
the purge control solenoid valve.
Purge Control Solenoid Valve (PCSV) The purge control solenoid valve is controlled
by the Engine Control Module (ECM); when theengine coolant temperature is low during idling,the PCSV closes so that evaporated fuel is nottaken into the engine. After the engine warms-up during ordinary driving, the PCSV opens soas to introduce evaporated fuel to the engine. H010B01A-AAT
1. Crankcase Emission Control
System
The Positive Crankcase Ventilation System is
employed to prevent air pollution caused byblow-by gases being emitted from the crank-case. This system supplies fresh filtered air tothe crankcase through the air intake hose.Inside the crankcase, the fresh air mixes withblow-by gases, then passes through the PCVvalve into the induction system.
The catalytic converter is part of the exhaust
emission control system. Its purpose is to re-move certain engine emission products fromthe engine's exhaust. It looks something like amuffler and is located underneath the car in the
exhaust system.
