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.

7Recommended engine coolant• When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
• The engine in your vehicle has aluminum engine parts and must be protected by
an ethylene-glycol-based coolant to pre-
vent corrosion and freezing.
• DO NOT USE alcohol or methanol coolant or mix them with the specified
coolant.
• Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixture percentage, refer to the fol-
lowing table.
Changing the coolantHave coolant changed by an authorized
HYUNDAI dealer according to the
Maintenance Schedule at the beginning
of this section.
WARNING -
Radiator cap
Do not remove the radiator cap
when the engine and radiator are
hot. Scalding hot coolant and
steam may blow out under pres-
sure causing serious injury.
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.

Maintenance
Replace the filter according to the
Maintenance Schedule.If the vehicle is operated in extremelydusty 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 dirtdoes not enter the air intake, ordamage may result.
• Use a HYUNDAI genuine part. Use of non-genuine parts could dam-age the air flow sensor.

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.)
