What to do in an emergency
TPMS malfunctions may occur for a
variety of reasons, including theinstallation of replacement or alter-
nate tires or wheels on the vehicle
that prevent the TPMS from function-
ing properly. Always check the TPMSmalfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replace-
ment or alternate tires and wheels
allow the TPMS to continue to func-
tion properly.
✽✽NOTICE
If the TPMS Low Tire Pressure
Telltale does not illuminate for three
seconds when the ignition switch is
in the ON position or when the
engine starts, or if it remains illumi-
nated after coming on for approxi-
mately three seconds, take your
vehicle to your nearest authorized
HYUNDAI dealer and have the sys-
tem checked.
Low Tire Pressure
Telltale
The TPMS is not a substitute for
manually checking tire pressure with
a tire pressure gauge. Changes in
temperature affect tire pressure. See
“Tires and Wheels” in chapter 7 forproper tire inflating and tire pressure
measurement procedures.
Immediately reduce your speed,
avoid hard cornering and anticipate
increased stopping distances. You
should stop and check your tires as
soon as possible. Inflate the tires tothe proper pressure as indicated on
the vehicle’s placard or tire inflation
pressure label located on the driver’s
side door jamb. If you cannot reach a
service station or if the tire cannot
hold the newly added air, replace the
low pressure tire with the compact
spare tire. The Low Tire Pressure Telltale will
remain on and the TPMS Malfunction
Indicator may blink for one minuteand then remain illuminated if the
vehicle is driven approximately 20
minutes at speed above 15.5 mph(25 km/h).
✽✽
NOTICE
The compact spare tire is not
equipped with a tire pressure sensor.

The following lists are vehicle checks and inspections that should be per-
formed by the owner or an author-
ized HYUNDAI dealer at the frequen-
cies indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
warranties and you may be charged
for labor, parts and lubricants used.
Performing maintenance work
on a vehicle can be dangerous.
If you lack sufficient knowledge
and experience or the propertools and equipment to do the
work, have it done by an author-
ized HYUNDAI dealer. ALWAYS
follow these precautions for
performing maintenance work:
Park your vehicle on level
ground, move the shift lever
into the P (Park, for automatic
transaxle vehicle) position or
neutral (for manual transaxle
vehicle, apply the parking
brake, place the ignition
switch in the OFF position.
Block the tires (front and
back) to prevent the vehicle
from moving.
Remove loose clothing or jew-
elry that can become entan-
gled in moving parts.
(Continued)
WARNING (Continued)
If you must run the engine
during maintenance, do so
out doors or in an area withplenty of ventilation.
Keep flames, sparks, or smok-
ing materials away from the
battery and fuel-related parts.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-tion.
Notice if your vehicle constantly turns slightly or “pulls” to one side
when traveling on smooth, levelroad.
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 operation of your transaxle occurs,
check the transaxle fluid level.
Check the automatic transaxle P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flash-
ers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,or are damaged.
Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of theopening and cause serious
burns and other injuries.

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 frequent oil and filter changesare required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as 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 excessive amount of
foreign matter accumulates 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. Fuel filters
should be installed by an authorized
HYUNDAI dealer.
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized HYUNDAI
dealer replace any damaged or leak-
ing parts immediately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vaporhose or fuel filler cap is correctlyreplaced.
Air cleaner filter
A genuine HYUNDAI air cleaner filter is recommended when the filter isreplaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.

authorized HYUNDAI dealer inaccordance to the scheduled mainte-nance at the beginning of this chap-
ter.
✽✽NOTICE
Automatic transaxle fluid color is
basically red.
As the vehicle is driven, the auto-
matic transaxle fluid will begin to
look darker. This is a normal condi-
tion and you should not judge the
need to replace the fluid based upon
the changed color.
The use of a non-specified fluid could result in transmission
malfunction and failure. Use
only the specified automatic
transaxle fluid (refer to“Recommended Lubricants and
Capacities” in chapter 8).
