Maintenance
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labor, parts and
lubricants used.
Owner maintenance schedule
When you stop for fuel:
 Check the engine oil level.
 Check coolant level in coolant reser-
voir.
 Check the windshield washer fluid
level.
 Look for low or under-inflated tires.
WARNING
- Maintenance
work
 Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorized HYUNDAI dealer.
 Working under the hood with the
engine running is dangerous. It
becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while work-
ing under the hood, make certain
that you remove all jewelry (espe-
cially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose cloth-
ing before getting near the
engine or cooling fans.
OWNER MAINTENANCE
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns
or other serious injury.

Maintenance

While operating your vehicle:
 Note any changes in the sound of the
exhaust 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-ahead
position.
 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 transaxle occurs, check
the transaxle fluid level.
 Check automatic transaxle 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 coolant level in the engine
coolant 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 radiator, heater and air condi-
tioning hoses for leaks or damage.
 Check windshield washer spray and
wiper operation. Clean wiper blades
with clean cloth dampened with wash-
er fluid.
 Check headlight alignment.
 Check muffler, exhaust pipes, shields
and clamps.
 Check the lap/shoulder belts for wear
and function.
 Check for worn tires and loose wheel
lug nuts.
At least once a year:
 Clean body and door drain holes.
 Lubricate door hinges and checks, and
hood hinges.
 Lubricate door and hood locks and
latches.
 Lubricate door rubber weatherstrips.
 Check the air conditioning system.
 Inspect and lubricate automatic
transaxle linkage and controls.
 Clean battery and terminals.
 Check the brake fluid level.

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.
Valve clearance
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI dealer should
perform the operation.
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 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.
✽
✽
NOTICE
Automatic 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 lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake/clutch fluid
Check 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.)

The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.
Checking the coolant level
(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.
ENGINE COOLANT
WARNING
Removing radiator
cap
 Never attempt to remove the radi-
ator cap while the engine is oper-
ating or hot. Doing so might lead
to 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 cool-
ing system. When you are sure all
the pressure has been released,
press down on the cap, using a
thick towel, and continue turning
counterclockwise to remove it.
(Continued)
WARNING
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use extreme
caution when working near the
blades of the cooling fan so that
you are not injured by a rotating fan
blades. As the engine coolant tem-
perature decreases, the electric
motor will automatically shut off.
This is a normal condition. If your
vehicle is equipped with GDI, the
electric motor (cooling fan) may
operate until you disconnect the
negative battery cable.
