2. Use your finger to feel inside the hole. The oil level should be at its bottom edge. If it isnot, check for leaks before adding oil. Torefill the transaxle or bring the oil level up,add oil slowly until it reaches the properlevel. Do not overfill.
2. If the level is correct, lubricant should begin
to drip from the plug orifice. In this case theplug should be replaced. If the level is incor-rect, lubricant should be added until it beginsto drip from the plug orifice at which time theplug should be replaced.

DO-IT-YOURSELF MAINTENANCE 6-11
While the engine is idling, apply the brakes and move the gear selector lever from "P" to each
of its other positions — "R", "N", "D", "2", "L" —and then return to "N". With the engine stillidling:
1. Open the hood, being careful to keep hands, long hair and clothing clear of any movingparts.
2. Remove the transaxle dipstick, wipe it clean, reinsert the dipstick as far as it will go, thenremove it again. Now check the fluid level on
the dipstick. It should be in the "HOT" rangeon the dipstick.
Fluid level must be within this range
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through the dipsticktube until the level reaches the "HOT" range.
Do not overfill.

G120A01A-AAT CHECKING THE BRAKES CAUTION: Because brakes are essential to the safe oper- ation of the car, it is suggested that they bechecked and inspected by your Hyundai dealer.The brakes should be checked and inspectedfor wear at those intervals specified in thevehicle maintenance schedule in Section 5. G120B01A-AAT
Checking the Brake Fluid Level WARNING:
Use caution when handling brake fluid. It
can damage your vision if it gets into your eyes. It will also damage your vehicle’s paint
if spilled on it and not removed immediately.
G120C02A-AAT
Recommended Brake Fluid Use only hydraulic brake fluid conforming to
DOT 3 or DOT 4 specifications in your brakingsystem. Follow the instructions printed on thecontainer.
G120D01A-AAT
To Check the Fluid Level The fluid level in the brake fluid reservoir should
be checked periodically. The level should bebetween the "MIN" and "MAX" marks on theside of the reservoir. If the level is at or below
the "MIN" mark, carefully add fluid to bring it upto "MAX". Do not overfill.
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. NOTE:
Only lint free cloth should be used for wip-
ing the dipstick. The presence of lint within the transaxle may cause problems with thenormal function of the transaxle.

EMISSION CONTROL SYSTEMS 7-1
H010A01A-GAT EMISSION CONTROL SYSTEM (Not all models) 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. ZH000A1-A
7. EMISSION
CONTROL SYSTEMS
H010B01A-AAT
1. Crankcase Emission Control Sys-
tem
The Positive Crankcase Ventilation System is
employed to prevent air pollution caused by blow-by gases being emitted from the crank- case. This system supplies fresh filtered air to
the crankcase through the air intake hose.Inside the crankcase, the fresh air mixes with
blow-by gases, which then pass through thePCV valve and into the induction system.
H010D01A-AAT
3. Exhaust Emission Control SystemThe Exhaust Emission Control System is a
highly effective system which controls exhaust
emission while maintaining good vehicle perfor-mance.
H010C02A-GAT
2. Evaporative Emission
Control System (Not all models)
The Evaporative Emission Control System is
designed to prevent fuel vapors from escapinginto the atmosphere.
Canister While the engine is inoperative, fuel vapours
generated inside the fuel tank are absorbed and stored in the onboard canister. When the en-gine is running, the fuel vapors absorbed in thecanister are drawn into the induction systemthrough the purge control solenoid valve.
Purge Control Solenoid Valve The purge control solenoid valve is controlled
by the ECM; when the engine coolant temper- ature is low, and during idling, it closes, so that
evaporated fuel is not taken into the engine.
After engine warm-up, during ordinary driving, itopens so as to introduce evaporated fuel to theengine.
H020A01ACatalytic Converter
H020A01A-GAT CATALYTIC CONVERTER (Not all models) The catalytic converter is part of the exhaust
emission control system. Its purpose is to re- move certain engine emission products from
the engine’s exhaust. It looks something like amuffler and is located underneath the car in theexhaust system.
