(Continued) The vehicle can easily roll off
the jack causing serious
injury or death. No person
should place any portion of
their body under a vehicle that
is supported only by a jack;
use vehicle support stands.
Do not start or run the engine
while the vehicle is on the
jack.
Do not allow anyone to remain
in the vehicle while it is on the
jack.
Make sure any children pres-
ent are in a secure place away
from the road and from the
vehicle to be raised with the
jack.

What to do in an emergency
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 cor-
rect pressure. If it is too high, adjust
it until 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 pos-
sible.
After you have changed wheels,
always secure the flat tire in its place
and return the jack and tools to their
proper storage locations.To prevent the jack, jack handle,
wheel lug nut wrench and spare tire
from rattling while the vehicle is in
motion, store them properly.
CAUTION
Your vehicle has metric threads
on the wheel studs and nuts.
Make certain during wheel
removal that the same nuts that
were removed are reinstalled -
or, if replaced, that nuts with
metric threads and the same
chamfer configuration are used.
Installation of a non-metric
thread nut on a metric stud or
vice-versa will not secure the
wheel to the hub properly and
will damage the stud so that it
must be replaced.
Note that most lug nuts do not
have metric threads. Be sure to
use extreme care in checking
for thread style before installing
aftermarket lug nuts or wheels.
If in doubt, consult an author-
ized Hyundai dealer.
WARNING
- Wheel studs
If the studs are damaged, they
may lose their ability to retain
the wheel. This could lead to the
loss of the wheel and a collision
resulting in serious injuries.
WARNING -
Inadequate
spare tire pressure
Check the inflation pressures as
soon as possible after installing
the spare tire. Adjust it to the
specified pressure, if necessary.
Refer to Section 9,
Specifications.

What to do in an emergency
When towing your vehicle in an emer-
gency without wheel dollies :
1. Set the ignition switch in the ACC posi-
tion.
2. Place the transaxle shift lever in N
(Neutral).
3. Release the parking brake.
Emergency towingIf towing is necessary, we recommend
you to have it done by an authorized
Hyundai dealer or a commercial tow
truck service.
If towing service is not available in an
emergency, your vehicle may be tem-
porarily towed using a cable or chain
secured to the emergency towing hook
under the front (or rear) of the vehicle.Use extreme caution when towing the
vehicle. A driver must be in the vehicle to
steer it and operate the brakes.
Towing in this manner may be done only
on hard-surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, power train, steering and
brakes must all be in good condition.
Do not use the tow hooks to pull a vehi-
cle out of mud, sand or other condi-
tions from which the vehicle cannot be
driven out under its own power.
Avoid towing a vehicle heavier than the
vehicle doing the towing.
The drivers of both vehicles should
communicate with each other frequent-
ly.
CAUTION
Failure to place the transaxle shift
lever in N (Neutral) may cause inter-
nal damage to the transaxle.

What to do in an emergency22 6 Before emergency towing, check that
the hook is not broken or damaged.
Fasten the towing cable or chain
securely to the hook.
Do not jerk the hook. Apply steady and
even force.
To avoid damaging the hook, do not
pull from the side or at a vertical angle.
Always pull straight ahead. Use a towing strap less than 16 feet (5
m) long. Attach a white or red cloth
(about 12 inches (30 cm) wide) in the
middle of the strap for easy visibility.
Drive carefully so that the towing strap
is not loosened during towing.
CAUTION
Attach a towing strap to the tow
hook.
Using a portion of the vehicle
other than the tow hooks for tow-
ing may damage the body of your
vehicle.
Use only a cable or chain specifi-
cally intended for use in towing
vehicles. Securely fasten the
cable or chain to the towing hook
provided.
WARNING
Use extreme caution when towing
the vehicle.

driving maneuvers which would
place excessive stress on the
emergency towing hook and tow-
ing cable or chain. The hook and
towing cable or chain may break
and cause serious injury or dam-
age.
If the disabled vehicle is unable
to be moved, do not forcibly con-
tinue the towing. Contact an
authorized Hyundai dealer or a
commercial tow truck service for
assistance.
Tow the vehicle as straight ahead
as possible.
Keep away from the vehicle dur-
ing towing.

Maintenance
Timing beltInspect all parts related to the timing belt
for damage and deformation. Replace
any damaged parts immediately.Vapor hose and fuel filler capThe vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap is
correctly replaced.
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 indi-
cate 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 dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, 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.
Air cleaner filterA Genuine Hyundai air cleaner filter is
recommended when the filter is
replaced.Spark plugsMake sure to install new spark plugs of
the correct heat range.Valve clearanceInspect excessive valve noise and/or
engine vibration and adjust if necessary.
A qualified technician should perform the
operation.Cooling systemCheck the cooling system parts, such as
radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.CoolantThe coolant should be changed at the
intervals specified in the maintenance
schedule.

Maintenance22 7WASHER FLUIDChecking the washer fluid level The reservoir is translucent so that you
can check the level with a quick visual
inspection.
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the parking brake Check the stroke of the parking brake by
counting the number of “clicks’’ heard
while fully applying it from the released
position. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly steep grade. If the stroke is more or
less than specified, have the parking
brake adjusted by an authorized Hyundai
dealer.
Stroke : 7 “clicks’’ at a force of
44 lbs (20 kg, 196 N).
WARNING -
Coolant
Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
Radiator coolant can severely
obscure visibility when sprayed
on the windshield and may cause
loss of vehicle control or damage
to paint and body trim.
Windshield Washer fluid agents
contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allow
sparks or flame to contact the
washer fluid or the washer fluid
reservoir. Damage to the vehicle
or occupants could occur.
Windshield washer fluid is poi-
sonous to humans and animals.
Do not drink and avoid contact-
ing windshield washer fluid.
Serious injury or death could
occur.
