To Check the Coolant Level
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "LOW" and "FULL"
lines on the reservoir when the engine is cold.
If the level is below the "LOW" mark, add
engine coolant to bring it up between "LOW"
and "FULL". If the level is low, inspect for
coolant leaks and recheck the fluid level fre-
quently. If the level drops again, visit your
Hyundai dealer for an inspection and diagnosis
of the reason.
G050D02A-AATTo Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
CAUTION:Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park-
ing brake and remove the radiator cap when
cool.
2. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow
all the engine coolant to drain from the
cooling system, then securely close the drain
cock.
3. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer’s directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
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 by
pushing down and turning counterclockwise.
Now fill the radiator with clean demineral-
ized or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.5. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed 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 the
blades of the coolant fan so that you are not
injured by a rotating fan blade. As the en-
gine coolant temperature decreases, the fan
will automatically shut off. This is a normal
condition.

G120C02A-AATRecommended Brake Fluid
Use only hydraulic brake fluid conforming to
DOT 3 or DOT 4 specifications in your braking
system. Follow the instructions printed on the
container.
G120D01A-AAT
To Check the Fluid LevelThe fluid level in the brake fluid reservoir should
be checked periodically. The level should be
between the "MIN" and "MAX" marks on the
side of the reservoir. If the level is at or below
the "MIN" mark, carefully add fluid to bring it up
to "MAX". Do not overfill.
G120E02A-AAT
Adding Brake FluidWARNING:
Handle brake fluid carefully. It can damage
your vision if it gets into your eyes. Use only
DOT 3 or DOT 4 specification fluid from a
sealed container. Do not allow the fluid can
or reservoir to remain open any longer than
required. This will prevent entry of dirt and
moisture which can damage the brake sys-
tem and cause improper operation.
To add brake fluid, first wipe away any dirt then
unscrew the fluid reservoir cap. Slowly pour the
recommended fluid into the reservoir. Do not
overfill. Carefully replace the cap on the reser-
voir and tighten.

CAUTION:
Because brakes are essential to the safe
operation of the car, it is suggested that
they be checked and inspected by your
Hyundai dealer. The brakes should be
checked and inspected for wear at those
intervals specified in the vehicle mainte-
nance schedule in Section 5.

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.
WARNING:The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper-
ate even when the engine is not running.

area.
o Do not permit flames, sparks or smoking in
the area.
o Keep children away from the area.
G220B01A-AATChecking Engine Cooling Fan
The engine cooling fan should come on auto-
matically if the engine coolant temperature is
high.

Checking the BatteryKeep the battery clean. Any evidence of corro-
sion around the battery posts or terminals should
be removed using a solution of household bak-
ing soda and warm water. After the battery
terminals are dry, cover them with a light coat-
ing of grease.

G210A01A-AATCHECKING THE BATTERY
WARNING:
Batteries can be dangerous! When working
with batteries, carefully observe the follow-
ing precautions to avoid serious injuries.
The fluid in the battery contains a strong solu-
tion of sulfuric acid, which is poisonous and
highly corrosive. Be careful not to spill it on
yourself or the car. If you do spill battery fluid on
yourself, immediately do the following:
o If battery fluid is on your skin, flush the
affected areas with water for at least 15
minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your
eyes with water and get medical assistance
as soon as possible. While you are being
driven to get medical assistance, continue
to rinse your eyes by using a sponge or soft
cloth saturated with water.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk of
magnesia, eat a raw egg or drink vegetable
oil. Get medical assistance as soon as
possible.
While batteries are being charged (either by a
battery charger or by the vehicle’s generator),
they produce explosive gases. Always observe
these warnings to prevent injuries from occur-

7. EMISSION CON-
TROL SYSTEMSH010B01A-AAT1. Crankcase Emission Control
System
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 the
PCV valve and into the induction system.
H010C01S-AAT2. Evaporative Emission Control (In-
cluding ORVR: Onboard Refueling
Vapor Recovery) System
The Evaporative Emission Control System is
designed to prevent fuel vapors from escaping
into the atmosphere.
(The ORVR system is designed to allow the
vapors from the fuel tank to be loaded into
a canister while refueling at the gas station,
preventing the escape of fuel vapors into
the atmosphere.)
Canister
Fuel vapors generated inside the fuel tank are
absorbed and stored in the onboard canister.
When the engine is running, the fuel vapors
absorbed in the canister are drawn into the
induction system through the purge control so-
lenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is controlled
by the Engine Control Module (ECM); when the
engine coolant temperature is low during idling,
the PCSV closes so that evaporated fuel is not
taken into the engine. After the engine warms-
up during ordinary driving, the PCSV opens to
introduce evaporated fuel to the engine.
H010D01A-AAT
3. Exhaust Emission Control System
The Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle per-
formance.
H010A01GK-AAT
EMISSION CONTROL SYSTEM
Your Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air Resources Board.
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 ensure 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 this
manual.
Caution for Inspection and Maintenance Test
(Vehicle with Traction Control System)
o To prevent the vehicle from misfiring
during dynamometer testing, disconnect
the ABS connector located inside of the
wheel guard (driver side).
o For more information, see shop manual
(BR Group, Wheel Speed Sensor).
