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 transported to an emergency facil-
ity, 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 deter-
mine 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 illustration. 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 con-
nect 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 dis-
charged battery using the normal starting
procedure. After the engine starts, leave the
jumper cables connected 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.
D020A03A-AAT
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.

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 seri-
ous 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 fur-
ther 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 overheat-
ing, 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" (auto-
matic) 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 damaged in towing. Also, profes-
sionals are generally aware of local laws gov-
erning 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.

CAUTION:
o Automatic Transaxle:
Be sure to use a towing dolly under the front
wheels.
A vehicle with an automatic transaxle should
never be towed from the rear with the front
wheels on the ground. This can cause se-
rious damage to the transaxle.
3) It is recommended that your vehicle be
towed with all the wheels off the ground.
EMERGENCY TOWINGD080D01NF-AAT
!
D080D02NF-A
For emergency towing when no commercial
tow vehicle is available, attach a tow cable,
chain or strap to the towing hook under the front
of your car. Do not attempt to tow your vehicle
in this manner on any unpaved surface. This
could result in serious damage to your car.
Nor should towing be attempted if the wheels,
drive train, axles, steering or brakes are dam-
aged. Before towing, be sure the transaxle is in
neutral and the key is in "ACC" (with the engine
off) or in the "ON" position (with the engine
running). A driver must be in the towed car to
steer it and operate the brakes.
CAUTION:
If the car is being towed with all four wheels
on the ground, it can be towed only from the
front. Be sure that the transaxle is in neutral.
Do not tow at speeds greater than 30 mph
(50 km/h) and for more than 15 miles (25
km). Be sure the steering is unlocked by
placing the key in the "ACC" position. A
driver must be in the towed vehicle to
operate the steering and brakes.NOTE:Before towing, check the level of the auto-
matic transaxle fluid. If it is below the "HOT"
range on the dipstick, add fluid. If you
cannot add fluid, a towing dolly must be
used.

CORROSION PREVENTION AND APPEARANCE CARE4
If you find any nicks or scratches in the paint,
use touch-up paint to cover them to prevent
corrosion. To protect the paintwork of the car
against corrosion, you must clean your Hyundai
(at least once a month). Give special attention
to the removal of salt, mud and other sub-
stances on the underside of the splashboards
of the car. Make sure that the outlets and the
underside of the doors are open. Paint damage
can be caused by small accumulation of tar,
industrial precipitation, tree resin, insects and
bird droppings, when not removed immediately.
If water alone is not strong enough to remove the
accumulated dirt, use a mild car washing solu-
tion. Be sure to rinse the surface after washing
to remove the solution. Never allow the solution
to dry on the painted surfaces. To clean whitewall tires, use a stiff brush or
soapy steel-wool scouring pad.
To clean plastic wheel covers, use a clean
sponge or soft cloth and water.
To clean cast aluminum alloy wheels, use a mild
soap or neutral detergent. Do not use abrasive
cleaners. Protect the bare-metal surfaces by
cleaning, polishing and waxing. Because alumi-
num is subject to corrosion, be sure to give
aluminum alloy wheels special attention in win-
ter. If you drive on salted roads, clean the
wheels thoroughly afterwards.
After washing, be sure to rinse thoroughly. If
soapy water dries on the finish, streaking will
result.
When the weather is warm and the humidity low,
you may find it necessary to rinse each section
immediately after washing to avoid streaking.
After rinsing, dry the car using a damp chamois
or soft, absorbent cloth. The reason for drying
the car is to remove water from the car so it will
dry without water spots. Don't rub, this can
damage the finish.
CAUTION:
!
OJB037800
o Water washing in the engine compart-
ment including high pressure water
washing may cause the failure of electri-
cal circuits located in the engine com-
partment.
o Never allow water or other liquids to
come in contact with electrical/electronic
components inside the vehicle as this
may damage them.

F060D01A-AATo Fuel Lines, Fuel Hoses and Connec-
tionsCheck the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
technician replace any damaged or leaking
parts immediately.F060B01NF-GATo Drive BeltsInspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation and
replace if necessary. Drive belts should be
checked periodically for proper tension.
F060M01A-AATo Engine Oil and FilterThe engine oil and filter should be changed at the
intervals specified in the maintenance sched-
ule. If the car is being driven in severe condi-
tions, more frequent oil and filter changes are
required.F060C01A-AATo Fuel FilterA clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an exces-
sive 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.
