3. Exhaust emission control
system
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could affect
its performance, safety or durability and
may even violate governmental safety
and emissions regulations.
In addition, damage or performance
problems resulting from any modification
may not be covered under warranty.
Engine exhaust gas precautions (car-
bon monoxide)
Carbon monoxide can be present with other exhaust fumes. Therefore, if you
smell exhaust fumes of any kind inside
your vehicle, have it inspected and
repaired immediately. If you ever sus-
pect exhaust fumes are coming into
your vehicle, drive it only with all the
windows fully open. Have your vehicle
checked and repaired immediately. Do not operate the engine in confined
or closed areas (such as garages) any
more than what is necessary to move
the vehicle in or out of the area.
When the vehicle is stopped in an open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.
Never sit in a parked or stopped vehi- cle for any extended time with the
engine running.
When the engine stalls or fails to start, excessive attempts to restart the
engine may cause damage to the
emission control system.
WARNING- Exhaust
Engine exhaust gases contain car-
bon monoxide (CO). Though color-
less and odorless, it is dangerous
and could be lethal if inhaled.
Follow the instructions on this
page to avoid CO poisoning.

CALIFORNIA PROPOSI-
TION 65 WARNING
Engine exhaust and a wide variety
of automobile components and
parts, including components found
in the interior furnishings in a vehi-
cle, contain or emit chemicals
known to the State of California to
cause cancer and birth defects and
reproductive harm. In addition, cer-
tain fluids contained in vehicles
and certain products of component
wear contain or emit chemicals
known to the State of California to
cause cancer and birth defects or
other reproductive harm.

Operating precautions for catalyt-
ic converters (if equipped)
Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
Use only UNLEADED FUEL for gaso-line engine.
Do not operate the vehicle when there are signs of engine malfunction, such
as misfire or a noticeable loss of per-
formance.
Do not misuse or abuse the engine. Examples of misuse are coasting with
the ignition off and descending steep
grades in gear with the ignition off. Do not operate the engine at high idle
speed for extended periods (5 minutes
or more).
Do not modify or tamper with any part of the engine or emission control sys-
tem. All inspections and adjustments
must be made by an authorized
Hyundai dealer.
Avoid driving with a very low fuel level. If you run out of gasoline, it could
cause the engine to misfire and result
in excessive loading of the catalytic
converter.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void your
warranties. Perchlorate Material-special handling
may apply, See www.dtsc.ca.gov/haz-
ardouswaste/perchlorate.
Notice to California Vehicle Dismantlers:
Perchlorate containing materials, such as
airbag inflators, seatbelt pretensioners
and keyless remote entry batteries, must
be disposed of according to Title 22
California Code of Regulations Section
67384.10 (a).
WARNING- Fire
A hot exhaust system can ignite
flammable items under your vehi-
cle. Do not park, idle, or drive the
vehicle over or near flammable
objects, such as dry grass, paper,
leaves, etc.

RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality. The correct
lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.
*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econo my by reducing the amount of fuel nec-
essary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s time , they can offer significant cost and
energy savings.
*
3If the API service SM engine oil is not available in your country, you are able to use API service SL.
Lubricant Volume Classification
4.23 US qt. (4.0 l)
Manual transaxle fluid 2.11 US qt. (2.0 l) API Service GL-4 (SAE 75W-85, fill for-life)
HYUNDAI GENUINE ATF SP-III, DIAMOND ATF SP-III,
Automatic transaxle fluid 6.97 US qt. (6.6 l) SK ATF SP-III or other brands metting the SP-III specification
approved by Hyundai Motor Co.
Coolant 6.97 US qt. (6.6 l) MIXTURE, Antifreeze with water
(Ethylene glycol base coolant for aluminum radiator)
Brake/Clutch fluid 0.7~0.8 US qt. (0.7~0.8 l) FMVSS116 DOT-3 or DOT-4
Fuel 14 US gal. (53 l) Dump octane number ((R+M)/2) : 87 or higher
Engine oil *1 *2
(drain and refill)
API Service SM*3,
ILSAC GF-4 or above

Recommended SAE viscosity
number Engine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operation (engine start and engine oil
flowability). Lower viscosity engine oils
can provide better fuel economy and cold
weather performance, however, higher
viscosity engine oils are required for sat-
isfactory lubrication in hot weather. Using
oils of any viscosity other than those rec-
ommended could result in engine dam-
age.When choosing an oil, consider the range
of temperature your vehicle will be oper-
ated in before the next oil change.
Proceed to select the recommended oil
viscosity from the chart.
CAUTION
Always be sure to clean the area
around any filler plug, drain plug, ordipstick before checking or drain-ing any lubricant. This is especially important in dusty or sandy areasand when the vehicle is used onunpaved roads. Cleaning the plug and dipstick areas will prevent dirtand grit from entering the engineand other mechanisms that couldbe damaged.

*1. For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE 5W-
20 (API SM / ILSAC GF-4). However, if the engine oil is not available in your country, select
the proper engine oil using the engine oil viscosity chart.

Tire specification/pressure label
The tires supplied on your new vehicle
are chosen to provide the best perform-
ance for normal driving.
The tire label located on the driver's side
of the center pillar outer panel gives the
tire pressures recommended for your car.
Engine number
The engine number is stamped on the
engine block as shown in the drawing.
