Introduction
Gasoline engine
Unleaded
For Europe
For the optimal vehicle performance, we
recommend you to use unleaded gaso-
line with an octane rating of RON(Research Octane Number) 95 / AKI
(Anti Knock Index) 91 or higher.
You may use unleaded gasoline with an
octane rating of RON 91~94 / AKI 87~90
but it may result in slight performance
reduction of the vehicle.
Except Europe
Your new HYUNDAI vehicle is designed
to use only unleaded fuel having an
Octane Rating of RON (Research
Octane Number) 91 / AKI (Anti-Knock
Index) 87 or higher.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.
Leaded (if equipped)
For some countries, your vehicle is
designed to use leaded gasoline. When
you are going to use leaded gasoline,
ask an authorized HYUNDAI dealer
whether leaded gasoline in your vehicle
is available or not. Octane Rating of leaded gasoline is
same with unleaded one.
FUEL REQUIREMENTS
WARNING
• Do not "top off" after the nozzle automatically shuts off when refueling.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-dent.
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and willdamage the engine control sys-tem’s oxygen sensor and affect emission control.
Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (Consultan authorized HYUNDAI dealer for
details.)

WARNING - ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the win-
dows immediately.
• Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxia- tion.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you hear
a change in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, we recom-
mend that the system be checked by an authorized HYUNDAI dealer.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine in your
garage any longer than it takes to start the engine and back the car out.
If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area
with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior.
If you must drive with the trunk lid open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at " " or " " and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshie ld are
kept clear of snow, ice, leaves or other obstructions.

WARNING - Driving under
the influence of alcohol or drugs
Drinking and driving is dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Drivingwhile under the influence of drugs
is as dangerous or more dangerousthan driving drunk.
You are much more likely to have a
serious accident if you drink or
take drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-er who has been drinking or taking
drugs. Choose a designated driveror call a cab.WARNING
When you intend to park or stop the vehicle with the engine on, be careful not to depress the accel-
erator pedal for a long period of
time. It may overheat the engine
or exhaust system and cause fire.
When you make a sudden stop or turn the steering wheel rapidly,
loose objects may drop on the
floor and it could interfere with
the operation of the foot pedals,
possibly causing an accident.
Keep all things in the vehicle
safely stored.
If you do not focus on driving, it may cause an accident. Be care-
ful when operating what may dis-
turb driving such as audio or
heater. It is the responsibility of
the driver to always drive safely.

Maintenance
While operating your vehicle:
Note any changes in the sound of theexhaust or any smell of exhaust fumes
in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-aheadposition.
Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
eling on smooth, level road.
When stopping, listen and check for unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
If any slipping or changes in the oper- ation of your transmission occurs,
check the transmission fluid level.
Check automatic transmission P (Park) function.
Check parking brake.
Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-mal).
At least monthly:
Check the coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
Check the inflation pressures of all tires including the spare.
At least twice a year
(i.e., every Spring and Fall):
Check the radiator, heater and air con- ditioning hoses for leaks or damage.
Check the windshield washer spray and wiper operation. Clean the wiper
blades with clean cloth dampened with
washer fluid.
Check the headlight alignment.
Check the muffler, exhaust pipes, shields and clamps.
Check the lap/shoulder belts for wear and function.
Check for worn tires and loose wheel lug nuts.

Maintenance
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
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 fre-quent oil and filter changes are required. Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if 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 exces-
sive amount of foreign matter accumu-
lates 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. We recommend that
the fuel filter be replaced by an author-
ized HYUNDAI dealer.
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. We
recommend that the fuel lines, fuel hoses
and connectionsr be replaced by an
authorized HYUNDAI dealer.Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap iscorrectly replaced.
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold. Inspect the hose routing to assure that the hoses do not come in contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.

Bright-metal maintenance
To remove road tar and insects, use a
tar remover, not a scraper or other
sharp object.
To protect the surfaces of bright-metal parts from corrosion, apply a coating of
wax or chrome preservative and rub to
a high luster.
During winter weather or in coastal areas, cover the bright metal parts with
a heavier coating of wax or preserva-
tive. If necessary, coat the parts with
non-corrosive petroleum jelly or other
protective compound.
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may col-
lect on the underbody. If these materials
are not removed, accelerated rusting can
occur on underbody parts such as the
fuel lines, frame, floor pan and exhaust
system, even though they have been
treated with rust protection.
Thoroughly flush the vehicle underbody
and wheel openings with lukewarm or
cold water once a month, after off-road
driving and at the end of each winter. Payspecial attention to these areas because
it is difficult to see all the mud and dirt. It
will do more harm than good to wet down
the road grime without removing it. The
lower edges of doors, rocker panels, and
frame members have drain holes that
should not be allowed to clog with dirt;
trapped water in these areas can cause
rusting.
Aluminum or chrome wheel mainte-
nance
The aluminum or chrome wheels are
coated with a clear protective finish.
Do not use any abrasive cleaner, pol- ishing compound, solvent, or wire
brushes on aluminum or chrome
wheels. They may scratch or damagethe finish.
Clean the wheel when it has cooled.
Use only a mild soap or neutral deter- gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
Avoid washing the wheels with high- speed car wash brushes.
Do not use any alkaline or acid deter- gent. It may damage and corrode the
aluminum or chrome wheels coated
with a clear protective finish.
WARNING
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.

EMISSION CONTROL SYSTEM (IF EQUIPPED)
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Service Passport
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 Program (ESP) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability
Program (ESP) system off by press-
ing the ESP switch.
After dynamometer testing is com- pleted, turn the ESP system back on
by pressing the ESP switch again. 1. Crankcase emission control
system
The 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 valveinto the induction system.
2. Evaporative emission control system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.

797
Maintenance
Canister
Fuel vapors generated inside the fuel tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in the
canister are drawn into the surge tank
through the purge control solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es so that evaporated fuel is not taken
into the engine. After the engine warms-
up during ordinary driving, the PCSV
opens to introduce evaporated fuel to the
engine.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.
If you use unauthorized electric devices, it may cause the vehicle to
operate abnormally, wire damage, bat-
tery discharge and fire. For your safety,
do not use unauthorized electric
devices.
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.
WARNING - Exhaust
Engine exhaust gases contain car-
bon monoxide (CO). Though color-
less and odorless, it is dangerousand could be lethal if inhaled.
Follow the instructions on this
page to avoid CO poisoning.

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 theemission control system.Operating precautions for catalytic
converters (if equipped)Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
Make sure to refuel your vehicle according to the “Fuel requirements”suggested in section 1.
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 withthe 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 minutesor more).
Do not modify or tamper with any part of the engine or emission control sys-
tem. We recommend that the system
be inspected by an authorized
HYUNDAI dealer.
Avoid driving with a very low fuel level. If you run out of gasoline, it couldcause the engine to misfire and result
in excessive loading of the catalytic
converter.
Failure to observe these precautionscould result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void your
warranties.
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 grass, vegeta-
tion, paper, leaves, etc.
The exhaust system and catalytic system are very hot while the
engine is running or immediately
after the engine is turned off.
Keep away from the exhaust sys-
tem and catalytic, you may get
burned.
Also, do not remove the heat sink
around the exhaust system, do
not seal the bottom of the vehicle
or do not coat the vehicle for cor-
rosion control. It may present a
fire risk under certain conditions.
