WHAT TO DO IN AN EMERGENCY
7
Have the system checked by an autho-
rized Hyundai dealer as soon as pos-
sible to determine the cause of the
problem.
NOTE:
o The TPMS malfunction indicator
may be illuminated if the vehicle
is operated in areas close to elec-
tric power supply cables or radio
transmitters such as near police
stations, government and public
offices, broadcasting stations,
military installations, airports, or
transmitting towers, etc. which can
interfere with normal operation of
the Tire Pressure Monitoring Sys-
tem (TPMS).
o The TPMS malfunction indicator
may be illuminated if snow chains
or some electronic devices, such
as notebook computers, are used
in the vehicle. This can interfere
with normal operation of the Tire
Pressure Monitoring System
(TPMS).o If there is a failed tire sensor, it is
possible for the TPMS to tempo-
rarily learn a replacement sensor
if closely driven to another vehicle
that is also equipped with TPMS.
In rare cases, this may tempo-
rarily delay the TPMS malfunction
indicator from turning on.
Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure telltale will turn on. Have the
flat tire repaired by an authorized Hyundai
dealer as soon as possible or replace
the flat tire with the temporary spare
tire. NEVER use a puncture-repairing
agent to repair and/or inflate a low
pressure tire. If used, you will have to
replace the tire pressure sensor.
Each wheel is equipped with a tire
pressure sensor mounted inside the tire
behind the valve stem. You must use
TPMS specific wheels. It is recom-
mended that you always have your tires
serviced by an authorized Hyundai
dealer.After you replace the low pressure tire
with the spare tire, the TPMS malfunc-
tion indicator or the Low Tire Pressure
telltale may illuminate after restarting
and driving for about 20 minutes.
Once the low pressure tire is re-inflated
to the recommended pressure and in-
stalled on the vehicle, the TPMS mal-
function indicator and the low tire pres-
sure telltale will extinguish. If the low
pressure and TPMS malfunction indi-
cators are not extinguished after about
20 minutes of continuous driving, please
visit an authorized Hyundai dealer.
You may not be able to identify a low tire
by simply looking at it. Always use a
good quality tire pressure gauge to
measure the tire's inflation pressure.
Please note that a tire that is hot (from
being driven) will have a higher pres-
sure measurement than a tire that is
cold (from sitting stationary for at least
3 hours and driven less than 1 mile
during that 3 hour period). Allow the tire
to cool before measuring the inflation
pressure.

D060J02O-AATAfter Changing Wheels
If you have a tire gauge, remove the
valve cap and check the air pressure. If
the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the correct
pressure. If it is too high, adjust it until Wheel nut tightening torque:
Steel wheel & aluminium alloy wheel:
65-80 lb.ft (900-1,100 kg.cm)
HNF5016-A
it is correct. Always reinstall the valve
cap after checking or adjusting tire
pressure. If the cap is not replaced, air
may leak from the tire. If you lose a
valve cap, buy another and install it as
soon as possible.
After you have changed wheels, al-
ways secure the flat tire in its place and
return the jack and tools to their proper
storage locations.
IF YOUR VEHICLE MUST BE
TOWEDD080A01O-GATIf your vehicle has to be towed, it should be
done by your Hyundai dealer or a
commercial tow truck service. This will
help assure that your vehicle is not dam-
aged in towing. Also, professionals are
generally aware of local laws governing
towing. In any case, rather than risk damage
to your car, it is suggested that you show
this information to the tow truck operator.
Be sure that a safety chain system is used
and that all local laws are observed.
It is recommended that your vehicle be
towed with a wheel lift and dollies or flatbed
equipment with all the wheels off the
ground.!
CAUTION:
o Your vehicle can be damaged if towed
incorrectly!
o Be sure the transaxle is in neutral.
o When the engine will not start, be sure
the steering is unlocked by placing
the key in the "ACC" position.

VEHICLE MAINTENANCE REQUIREMENTS2
F010C01A-AATSpecified Scheduled ProceduresThese are the procedures such as
inspections, adjustments and
replacements that are listed in the
maintenance charts starting on page 5-4.
These procedures must be performed at
the intervals shown in the maintenance
schedule to assure that your warranty
remains in effect. Although it is strongly
recommended that they be performed by
the trained technicians at your Hyundai
dealer, these procedures may be per-
formed at any qualified service facility.
It is suggested that genuine Hyundai
service parts be used for any required
repairs or replacements. Other parts of
equivalent quality such as engine oil,
engine coolant, manual or auto transaxle
oil, brake fluid and so on which are not
supplied by Hyundai Motor Company or its
distributor may be used without affecting
your warranty coverage but you should
always be sure these are equivalent to the
quality of the original Hyundai parts. Your
Owner's Handbook provides further
information about your warranty coverage.
F010A01A-AATService RequirementsTo ensure that you receive the greatest
number of miles of satisfying operation
from your Hyundai, certain maintenance
procedures must be performed. Although
careful design and engineering have
reduced these to a minimum, those that
are required are of the utmost importance.
It is your responsibility to have these main-
tenance procedures performed to comply
with the terms of the warranties covering
your new Hyundai. The Owner's Handbook
supplied with your new vehicle provides
further information about these warranties.
F010B01A-AATMaintenance RequirementsThe maintenance required for your
Hyundai can be divided into three main
areas:
o Specified scheduled procedures
o General checks
o Do-it-yourself maintenance

SCHEDULED MAINTENANCE
REQUIREMENTSF020A02Y-AATo Inspection should be performed any
time a malfunction is experienced or
suspected.
o Receipts for all emission control system
services should be retained to
demonstrate compliance with
conditions of the emissions system
warranty.
o After 120 months or 150,000 miles
(240,000 km), continue to follow the
prescribed maintenance intervals.
o For severe usage maintenance require-
ments, see page 5-6 of this section.
F010D02A-AATGeneral ChecksThese are the regular checks you should
perform when you drive your Hyundai or
you fill the fuel tank. A list of these items will
be found on page 6-4.F010E01A-AATDo-It-Yourself MaintenanceIf you are mechanically inclined, own a few
tools that are required and want to take the
time to do so, you can inspect and service
a number of items. For more information
about doing it yourself, see Section 6.
F010F01A-AATA Few Tipso Whenever you have your Hyundai
serviced, keep copies of the service
records in your glove box. This will help
ensure that you can document that the
required procedures have been
performed to keep your warranties in
effect. This is especially important when
service is not performed by an authorized
Hyundai dealer.
o If you choose to do your own
maintenance and repairs, you may find
it helpful to have an official Hyundai
Shop Manual. A copy of this publication
may be purchased at your Hyundai
dealer's parts department.

CHECKING AND CHANGING THE
ENGINE COOLANT!
G050A01A-AAT
WARNING:
Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and
may erupt through the opening if the cap
is removed. You could be seriously
burned if you do not observe this
precaution. Do not remove the radiator
cap until the radiator is cool to the touch.
!
5. Remove the oil filter by turning it counter-
clockwise with a oil filter wrench of the
proper size. A certain amount of oil will
come out when you remove the filter. So be
sure to have your drain pan in place
underneath it.
6. Install a new oil filter in accordance with the
instructions on the carton or on the filter
itself. Do not over-tighten.
Tightening torque:
8.7 ~ 11.6 lb.ft (1.2 ~ 1.6 kgf.m)
Be sure that the mounting surface on the
engine is clean and that the old gasket is
removed completely. Lubricate the new
gasket on the filter with clean engine oil
before installation.
7. Remove the engine oil level dipstick.
8. Refill the crankcase with the recommended
engine oil. Refer to the specification in
chapter 9 for engine oil capacity.
CAUTION:
Slowly pour the recommended oil into a
funnel. Do not overfill to avoid damage to
the engine.
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It
is suggested that it be placed in a sealed
container and taken to a service station
for reclamation. Do not pour the oil on the
ground or put it into the household trash.
