CALIFORNIA
PROPOSI-
TION 65 WARNING
Engine oil contains chemicals
known to the State of California to
cause cancer, birth defects, and
reproductive harm.
Used engine oil may cause irrita-
tion or cancer of the skin if left in
contact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory ani-
mals. Always protect your skin by
washing your hands thoroughly
with soap and warm water as soon
as possible after handling used oil.

Maintenance26 7
Changing the coolantHave coolant changed by an authorized
HYUNDAI dealer according to the
Maintenance Schedule at the beginning
of this section.
Checking the brake/clutch fluid
level Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap and
adding brake/clutch fluid, clean the area
around the reservoir cap thoroughly to
prevent brake/clutch fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings.
If the fluid level is excessively low, have
the brake system or clutch (if equipped)
checked by an authorized HYUNDAI
dealer.

BRAKE/CLUTCH FLUID
WARNING -
Coolant
 Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
 Radiator coolant can severely
obscure visibility when sprayed
on the windshield and may cause
loss of vehicle control or damage
to paint and body trim.
CAUTION
Put a thick cloth or fabric around
the radiator cap before refilling the
coolant in order to prevent the
coolant from overflowing into
engine parts such as generator.
WARNING
The cooling fan is controlled by
engine coolant temperature and
may sometimes operate 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 engine coolant tem-
perature decreases, the fan will
automatically shut off. This is a nor-
mal condition.

Maintenance30 7Replace the filter according to the
Maintenance Schedule.If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-
ment more often than the usual recom-
mended intervals. (Refer to
“Maintenance under severe usage condi-
tions” in this section.)
Filter inspectionThe climate control air filter should be
replaced according to the Maintenance
Schedule. If the vehicle is operated in
severely air-polluted cities or on dusty
rough roads for a long period, it should
be inspected more frequently and
replaced earlier. When you replace the
climate control air filter, replace it per-
forming the following procedure, and be
careful to avoid damaging other compo-
nents.
Filter replacement1. Open the glove box and remove the
support strap (1).
CAUTION
 Do not drive with the air cleaner
removed; this will result in exces-
sive engine wear.
 When removing the air cleaner fil-
ter, be careful that dust or dirt
does not enter the air intake, or
damage may result.
 Use a HYUNDAI genuine part. Use
of non-genuine parts could dam-
age the air flow sensor.

Maintenance
EMISSION CONTROL SYSTEMThe emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Owner’s
Handbook & Warranty Information book-
let in your vehicle.
Your vehicle is equipped with an emis-
sion control system to meet all applicable
emission regulations.
There are three emission control sys-
tems, 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 rec-
ommended that you have your car
inspected and maintained by an author-
ized HYUNDAI dealer in accordance with
the maintenance schedule in this manu-
al.Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
 To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability Control
(ESC) system off by pressing the
ESC switch.
 After dynamometer testing is com-
pleted, turn the ESC system back on
by pressing the ESC switch again.
1. Crankcase emission control
systemThe positive crankcase ventilation sys-
tem is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. 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
into the induction system.2. Evaporative emission control
(including ORVR: Onboard
Refueling Vapor Recovery)
systemThe Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
(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.)
