7Air cleaner filterA Genuine HYUNDAI air cleaner filter is
recommended when the filter is
replaced.Spark plugsMake sure to install new spark plugs of
the correct heat range.Valve clearance Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI dealer should
perform the operation.Cooling systemCheck cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
CoolantThe coolant should be changed at the
intervals specified in the maintenance
schedule.Manual transaxle fluid
(if equipped)Inspect the manual transaxle fluid
according to the maintenance schedule.Automatic transaxle fluid
(if equipped)Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, the fluid should
be changed at an authorized HYUNDAI
dealer in accordance to the scheduled
maintenance at the beginning of this
chapter.✽ ✽
NOTICEAutomatic transaxle fluid color is basi-
cally red.
As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.
Brake hoses and linesVisually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.Brake/clutch fluidCheck brake fluid level in the brake fluid
reservoir. The level should be between
“MIN” and “MAX” marks on the side of
the reservoir. Use only hydraulic brake
fluid conforming to DOT 3 or DOT 4
specification.
CAUTION
The use of a non-specified fluid
could result in transaxle malfunc- tion and failure.
Use only specified automatic trans -
axle fluid. (Refer to “Recommended lubricants and capacities” in sec-tion 8.)

AIR CLEANER Filter replacement It must be replaced when necessary, and
should not be cleaned and reused.
You can clean the filter when inspecting
the air cleaner element.
Clean the filter by using compressed air.1. Loosen the air cleaner cover attaching

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 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.

2. With the glove box open, remove thestoppers by turning them counter-
clockwise on both sides. 3. Remove the climate control air filter
cover while pressing the lock on the
right of the cover. 4. Replace the climate control air filter.
5. Reassemble in the reverse order of
disassembly.
✽ ✽NOTICEWhen replacing the climate control air
filter install it properly. Otherwise, the

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.)
