Engine Oil and Filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive Belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel Filter
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently. After
installing a new filter, run the engine
for several minutes, and check for
leaks at the connections. Fuel filters
should be installed by an authorized
HYUNDAI dealer.
Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized HYUNDAI
dealer replace any damaged or leak-
ing parts immediately.
Vapor Hose and Fuel Filler
Cap
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vapor
hose or fuel filler cap is correctly
replaced.
Air Cleaner Filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark Plugs
Make sure to install new spark plugs
of the correct heat range.

7-22
Maintenance
Valve Clearance (if equipped)
Inspect for excessive valve noise
and/or engine vibration and adjust if
necessary. Have an authorized
HYUNDAI dealer perform the opera-
tion.
Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic Transmission Fluid
Automatic transmission fluid should
not be checked under normal usage
conditions. But in severe conditions,
the fluid should be changed at an
authorized HYUNDAI dealer in accor-
dance to the scheduled maintenance
at the beginning of this chapter.
Automatic transmission fluid
color is basically red.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker. This is a normal
condition and you should not
judge the need to replace the fluid
based upon the changed color.
Ecoshift dual clutch transmis-
sion Fluid
Inspect the Ecoshift dual clutch
transmission fluid according to the
maintenance schedule.
NOTICE
The use of a non-specified fluid
could result in transmission
malfunction and failure. Use
only the specified automatic
transmission fluid (refer to
"Recommended Lubricants and
Capacities" in chapter 8).
CAUTION

Checking the Engine Oil and
Filter
Have engine oil and filter changed by
an authorized HYUNDAI dealer
according to the Maintenance
Schedule at the beginning of this
chapter.

WARNING
Engine oil contains chemicals
known to the State of California
to cause cancer, birth defects
and reproductive harm. Used
engine oil may cause irritation
or cancer of the skin if left in
contact with the skin for pro-
longed periods of time. Always
protect your skin by washing
your hands thoroughly with
soap and warm water as soon
as possible after handling used
oil.

Maintenance
For mixing percentage, refer to the
following table:
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of -
31°F and higher.
Changing Engine Coolant
Have coolant changed by an author-
ized HYUNDAI dealer according to
the Maintenance Schedule at the
beginning of this chapter.To prevent damage to engine
parts, put a thick towel around the
radiator cap before refilling the
coolant to prevent the coolant
from overflowing into engine
parts, such as the generator.

Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
Engine coolant can severely
obscure visibility when sprayed
on the windshield and may
cause loss of vehicle control
resulting in an accident.
Engine coolant may also cause
damage to paint and body trim.

Filter Inspection
The 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 performing the fol-
lowing procedure, and be careful to
avoid damaging other components.
1. With the glove box open, removethe stoppers on both sides to allow
the glove box to hang freely on the
hinges. 2. Remove the support rod (1).

The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Owner’s
Handbook & Warranty Information
booklet in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
applicable emission regulations.
There are three emission control
systems, as follows.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control sys- tem
(3) Exhaust emission control system
In order to assure the proper function
of the emission control systems, it is
recommended that you have your
vehicle inspected and maintained by
an authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.1. Crankcase Emission Control System
The positive crankcase ventilation
system 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 ControlSystem Including Onboard
Refueling Vapor Recovery
(ORVR)
The 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 can-
ister while refueling at the gas sta-
tion, preventing the escape of fuel
vapors into the atmosphere.
For the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
To prevent the vehicle from
misfiring during dynamome-
ter testing, turn the Electronic
Stability Control (ESC) sys-
tem off by pressing the ESC
switch (ESC OFF light illumi-
nated).
After dynamometer testing is
completed, turn the ESC sys-
tem back on by pressing the
ESC switch again.
CAUTION
