What to do in an emergency
Notes on the safe use of the
Tire Mobility Kit
Park your car at the side of theroad so that you can work with the
Tire Mobility Kit away from moving
traffic.
To be sure your vehicle will not move, even when you're on fairly
level ground, always set your park-
ing brake.
Only use the Tire Mobility Kit for sealing/inflation passenger car
tires. Only punctured areas located
within the tread region of the tire
can be sealed using the tire mobil-
ity kit.
Do not use on motorcycles, bicy- cles or any other type of tires.
When the tire and wheel are dam- aged, do not use Tire Mobility Kit
for your safety.
Use of the Tire Mobility Kit may not be effective for tire damage larger
than approximately 6 mm (0.24 in).
If the tire cannot be made roadwor-
thy with the Tire Mobility Kit, we
recommend that you contact an
authorized HYUNDAI dealer. Do not use the Tire Mobility Kit if a
tire is severely damaged by driving
run flat or with insufficient air pres-
sure.
Do not remove any foreign objects such as nails or screws that have
penetrated the tire.
Provided the car is outdoors, leave the engine running. Otherwise
operating the compressor may
eventually drain the car battery.
Never leave the Tire Mobility Kit unattended while it is being used.
Do not leave the compressor run- ning for more than 10 min. at a time
or it may overheat.
Do not use the Tire Mobility Kit if the ambient temperature is below
-30°C (-22°F).
In case of skin contact with the sealant, wash the area thoroughly
with plenty of water. If the irritation
persists, seek medical attention.
In case of eye contact with the sealant, flush your eyes for at least
15 minutes. If the irritation persists,
seek medical attention. In case of swallowing the sealant,
rinse the mouth and drink plenty of
water. However, never give any-
thing to an unconscious person
and seek medical attention imme-
diately.
Long time exposure to the sealant may cause damage to bodily tissue
such as kidney, etc.

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 proper
tools 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
transmission vehicle) posi-
tion, apply the parking brake,
place the ignition switch in
the LOCK/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 with
plenty 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, 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 operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission /ecoshift dual clutch transmission
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 flashers.
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 the
opening and cause serious
burns and other injuries.
