WHAT TO DO IN AN EMERGENCY
3
JUMP STARTING!
o If you should accidentally get acid on
your skin or in your eyes, immediately
remove any contaminated clothing and
flush the area with clean water for at
least 15 minutes. Then promptly obtain
medical attention. If you must be trans-
ported to an emergency facility, continue
to apply water to the affected area with
a sponge or cloth.
o The gas produced by the battery during
the jump-start operation is highly
explosive. Do not smoke or allow a
spark or an open flame in the vicinity.
o The battery being used to provide the
jump start must be 12-volt. If you cannot
determine that it is a 12-volt battery, do
not attempt to use it for the jump start.
o To jump start a car with a discharged
battery, follow this procedure exactly:
1. If the booster battery is installed in
another vehicle, be sure the two vehicles
are not touching.
2. Turn off all unnecessary lights and
acces-sories in both vehicles.
3. Attach the clamps of the jumper cable in
the exact location shown on the illustra-
tion. First, attach one clamp of the jumper
cable to the positive (+) post or cable of
the discharged battery.Then attach the other end of the same
cable to the positive (+) post or cable of
the booster battery. Next, using the other
cable, attach one clamp to the negative
(-) post or cable of the booster battery.
Then attach the other end of that cable
to a solid metal part of the engine of the
vehicle with the discharged battery
away from the battery. Do not connect
the cable to any moving part.
4. Start the engine in the car with the
booster battery and let it run for a few
minutes. This will help to assure that the
booster battery is fully charged. During
the jumping operation, run the engine
in this vehicle at about 2,000 rpm.
5. Start the engine in the car with the
discharged battery using the normal
starting procedure. After the engine
starts, leave the jumper cables con-
nected and let the engine run at fast idle
or about 2,000 rpm for several minutes.
6. Carefully remove the jumper cables in
the reverse order of attachment.
If you do not know why your battery became
discharged (because the lights were left
on, etc.), have the charging system checked
by your Hyundai dealer.

WARNING:
The gas produced by the battery during
the jump-start operation is highly
explosive. If these instructions are not
followed exactly, serious personal injury
and damage to the vehicle may occur! If
you are not sure how to follow this
procedure, seek qualified assistance.
Automobile batteries contain sulfuric
acid. This is poisonous and highly
corrosive. When jump starting, wear pro-
tective glasses and be careful not to get
acid on yourself, your clothing or on the
car.

34WHAT TO DO IN AN EMERGENCY
IF THE ENGINE OVERHEATS
!!
!
WARNING:
While the engine is running, keep hair,
hands and clothing away from moving
parts such as the fan and drive belts to
prevent injury.
5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the
engine immediately and call the nearest
Hyundai dealer for assistance.
WARNING:
Do not remove the radiator cap when the
engine is hot. This can allow coolant to be
blown out of the opening and cause se-
rious burns.6. If you cannot find the cause of the
overheat-ing, wait until the engine
temperature has returned to normal.
Then, if coolant has been lost, carefully
add coolant to the reservoir (page 6-9)
to bring the fluid level in the reservoir up
to the halfway mark.
7. Proceed with caution, keeping alert for
further signs of overheating. If
overheating happens again, call a
Hyundai dealer for assistance.
CAUTION:
Serious loss of coolant indicates there is
a leak in the cooling system and this
should be checked as soon as possible
by a Hyundai dealer.
D030A02A-AATIf your temperature gauge indicates over-
heating, you experience a loss of power, or
hear loud pinging or knocking, the engine
is probably too hot. If this happens, you
should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the gear selector lever in "P"
(automatic) or neutral (manual
transaxle) and set the parking brake. If
the air conditioning is on, turn it off.
3. If engine coolant is running out under
the car or steam is coming out from the
hood, stop the engine. Do not open the
hood until the coolant has stopped
running or the steaming has stopped. If
there is no visible loss of engine coolant
and no steam, leave the engine running
and check to be sure the engine cooling
fan is operating. If the fan is not running,
turn the engine off.
4. Check to see if the water pump drive belt
is missing. If it is not missing, check to
see that it is tight. If the drive belt seems
to be satisfactory, check for coolant
leaking from the radiator, hoses or under
the car. (If the air conditioning had been
in use, it is normal for cold water to be
draining from it when you stop).

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

the vehicle may be driven, damage the
emission system and cause 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 trained technicians.
F060F01A-AATo Vacuum, Crankcase Ventilation
HosesInspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indicate
deterioration. Particular attention should
be paid to examine those hose surfaces
nearest to high heat sources, such as the
exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving component
which might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are secure,
and that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
