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.

Air cleaner filter
We recommend that the air cleaner filter
be replaced by an authorized HYUNDAI
dealer. Spark plugs
Make 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.
We recommend that the system be
checked by an authorized HYUNDAI
dealer. Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts. Coolant The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transmission fluid (if equipped)
Inspect the manual transmission fluid
according to the maintenance schedule.Automatic transmission fluid (if equipped)
Automatic transmission fluid should not
be checked under normal usage condi-
tions.
We recommend that the automatic trans-
mission fluid be replaced by an author-
ized HYUNDAI dealer.
CAUTION
The use of a non-specified fluid
could result in transmission mal-function and failure.
Use only specified manual trans-mission fluid. (Refer to “Recommended lubricants and
capacities” in section 8.)

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach normal operating temperature.
3. Turn the engine off and wait for a few minutes (about 5 minutes) for the oil to
return to the oil pan. 4. Pull the dipstick out, wipe it clean, and
re-insert it fully.
5. Pull the dipstick out again and check the level. The level should be betweenF and L.
If it is near or at L, add enough oil to bring
the level to F.Do not overfill.
WARNING - Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may be
hot enough to burn you.

CAUTION
Do not overfill with engine oil. Engine damage may result.
Do not spill engine oil, when adding or changing engine oil. Ifyou drop the engine oil on the engine room, wipe it off immedi-ately.

ENGINE COOLANT
The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level at least once a year, at thebeginning of the winter season, and
before traveling to a colder climate. Checking the coolant level
WARNING
Removing radiatorcap
Never attempt to remove the radi- ator cap while the engine is oper-
ating or hot. Doing so might leadto cooling system and engine
damage and could result in seri-
ous personal injury from escap-ing hot coolant or steam.
Turn the engine off and wait until it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the
cooling system. When you aresure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
(Continued)
(Continued)
Even if the engine is not operat-ing, do not remove the radiator cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.

Recommended 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 alu- minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-ing.
DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
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 coolant
We recommend that the coolant be
replaced by an authorized HYUNDAI
dealer.
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.
CAUTION
Put a thick cloth around the radiator cap before refilling the coolant in order to prevent the coolant fromoverflowing into engine parts such
as the generator.
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.

WASHER FLUID
Checking the washer fluid level
The reservoir is translucent so that you
can check the level with a quick visualinspection.
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold cli-
mates to prevent freezing. Checking the parking brake
Check the stroke of the parking brake by
counting the number of “clicks’’ heardwhile fully applying it from the released
position. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly steep grade. If the stroke is more or
less than specified, we recommend that
the system be serviced by an authorized
HYUNDAI dealer.
Stroke : 5 notch at a force of 20 kg
(44 lbs, 196 N).
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.
Windshield Washer fluid agents contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allowsparks or flame to contact thewasher fluid or the washer fluid
reservoir. Damage to the vehicle
or occupants could occur.
Windshield washer fluid is poi- sonous to humans and animals.
Do not drink and avoid contacting
windshield washer fluid. Serious
injury or death could occur.

Specifications & Consumer information
*1
: Refer to the recommended SAE viscosity numbers on the next page.
* 2
: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy by reducing
the amount of fuel necessary 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.
