NORMAL MAINTENANCE SCHEDULE
The following maintenance services must be performed to ensure good emission control and performance. Keep
receipts for all vehicle emission services to protect your warranty. Where both mileage and time are shown, the fre-
quency of service is determined by whichever occurs first.
*
1: Check the engine oil level and leak every 350 miles
(500 km) or before starting a long trip.
*
2: The drive belt should be replaced when cracks occur
or tension is reduced excessively.
*
3: If TOP TIER Detergent Gasoline is not available, one
bottle of additive is recommended. Additives are
available from your authorized HYUNDAI dealer
along with information on how to use them. Do not
mix other additives.
*
4: Rear differential oil should be changed anytime they
have been submerged in water.
*
5: Fuel filter & Fuel tank air filter are considered to be
maintenance free but periodic inspection is recom-
mended for this maintenance schedule depends on
fuel quality. If there are some important safety matters
like fuel flow restriction, surging, loss of power, hard
starting problem etc, replace the fuel filter immediately
regardless of maintenance schedule and consult an
authorized HYUNDAI dealer for details.*
6: When adding coolant, use only deionized water or
soft water for your vehicle and never mix hard water
in the coolant filled at the factory. An improper coolant
mixture can result in serious malfunction or engine
damage.
*
7: Inspect for excessive valve noise and/or engine vibra-
tion and adjust if necessary. We recommend that the
system be checked by an authorized HYUNDAI dealer.

If any electrolyte gets
into your eyes, flush your
eyes with clean water for
at least 15 minutes and
get immediate medical
attention.
If electrolyte gets on your
skin, thoroughly wash
the contacted area. If you
feel a pain or a burning
sensation, get medical
attention immediately.
Wear eye protection
when charging or work-
ing near a battery.
Always provide ventila-
tion when working in an
enclosed space.
An inappropriately dis-
posed battery can be
harmful to the environ-
ment and human health.
Dispose the battery
according to your local
law(s) or regulation.
(Continued)
For best battery service
Keep the battery securely mount-
ed.
Keep the battery top clean and dry.
Keep the terminals and connec-
tions clean, tight, and coated with
petroleum jelly or terminal grease.
Rinse any spilled electrolyte from
the battery immediately with a
solution of water and baking soda.
If the vehicle is not going to be
used for an extended time, discon-
nect the battery cables.

WARNING- Battery
dangers
Always read the follow-
ing instructions carefully
when handling a battery.
Keep lighted cigarettes
and all other flames or
sparks away from the
battery.
Hydrogen, a highly com-
bustible gas, is always
present in battery cells
and may explode if ignit-
ed.
Keep batteries out of the
reach of children
because batteries con-
tain highly corrosive
SULFURIC ACID. Do not
allow battery acid to
contact your skin, eyes,
clothing or paint finish.

4. Tire ply composition and mate-
rial
The number of layers or plies of rub-
ber-coated fabric in the tire. Tire manu-
facturers also must indicate the materi-
als in the tire, which include steel,
nylon, polyester, and others. The letter
"R" means radial ply construction; the
letter "D" means diagonal or bias ply
construction; and the letter "B" means
belted-bias ply construction.
5. Maximum permissible inflation
pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREAD wear 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.WARNING - Tire age
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tires generally be replaced after
six (6) years of normal service.
Heat caused by hot climates or
frequent high loading condi-
tions can accelerate the aging
process. Failure to follow this
warning can result in sudden
tire failure, which could lead to
a loss of control and an acci-
dent involving serious injury or
death.

✽ ✽
NOTICE
HID lamps have superior perform-
ance vs. halogen bulbs. HID lamps
are estimated by the manufacturer to
last twice as long or longer than halo-
gen bulbs depending on their fre-
quency of use. They will probably
require replacement at some point in
the life of the vehicle. Cycling the
headlamps on and off more than typ-
ical use will shorten HID lamps life.
HID lamps do not fail in the same
manner as halogen incandescent
lamps. If a headlamp goes out after a
period of operation but will immedi-
ately relight when the headlamp
switch is cycled it is likely the HID
lamp needs to be replaced. HID light-
ing components are more complex
than conventional halogen bulbs thus
have higher replacement cost.
If the light bulb is not operating, have
the vehicle checked by an authorized
HYUNDAI dealer.
Front fog light bulb replacement
(if equipped)
1. Turn the steering wheel fully. (If
you want to replace driver side fog
lamp, turn the steering wheel to
the front passenger side.)
2. Open the hood.
3. Disconnect the negative battery
cable.
4. Loosen the retaining bolt on the
service cover. And then pull down
the service cover.
5. Remove the fog light bulb cover by
turning it counter clockwise.6. Remove the socket from the
assembly by turning the socket
counterclockwise until the tabs on
the socket align with the slots on
the assembly
7. Pull the bulb out of the socket.
8. Insert a new bulb into the socket.
9. Install the socket in the assembly
by aligning the tabs on the socket
with the slots in the assembly.
Push the socket into the assembly
and turn the socket clockwise.
10. Install the fog light bulb cover by
turning it clockwise. And then
assemble the service cover.
