What to do in an emergency
To prevent the jack, jack handle,
wheel lug nut wrench and spare tire
from rattling while the vehicle is in
motion, store them properly.
Important - use of temporary
compact spare tire
If your vehicle is equipped with a com-
pact spare tire, it will take up less
space than a regular-size tire. This tire
is smaller than a conventional tire and
is designed for temporary use only.
CAUTION
Your vehicle has metric threadson the wheel studs and nuts.Make certain during wheelremoval that the same nuts thatwere removed are reinstalled -or, if replaced, that nuts withmetric threads and the samechamfer configuration are used.Installation of a non-metricthread nut on a metric stud orvice-versa will not secure thewheel to the hub properly andwill damage the stud so that itmust be replaced.
Note that most lug nuts do nothave metric threads. Be sure touse extreme care in checkingfor thread style before installingaftermarket 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 “Tires and
wheels” section 8.
CAUTION
You should drive carefully when the compact spare is inuse. The compact spareshould be replaced by theproper conventional tire andrim at the first opportunity.
Do not use more than one compact spare tire at a time.

What to do in an emergency
When towing your vehicle in an
emergency without wheel dollies :
1. Set the ignition switch in the ACCposition.
2. Place the shift lever in N (Neutral).
3. Release the parking brake.
Removable towing hook
(if equipped)
1. Open the tailgate, and remove the towing hook from the tool case
which is stored under the cargo
area floorboard.
2. Remove the hole cover pressing the lower part of the cover on the
bumper.
3. Install the towing hook by turning it clockwise into the hole until it is
fully secured.
4. Remove the towing hook and install the cover after use.
Emergency towing (if equipped)
If towing is necessary, we recom-
mend you to have it done by an
authorized Hyundai dealer or a
commercial tow truck service.
CAUTION
Failure to place the transaxleshift lever in N (Neutral) maycause internal damage to thetransaxle.

If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook attached to the front (or
under the rear) of the vehicle.
Use extreme caution when towing the
vehicle. A driver must be in the vehi-
cle to steer it and operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a
short distance 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
vehicle out of mud, sand or other
conditions 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 fre-
quently. Before emergency towing, check
that the hook is not broken or dam-
aged.
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.CAUTION
Attach a towing strap to the tow hook.
Using a portion of the vehicle other than the tow hooks fortowing may damage the bodyof your vehicle.
Use only a cable or chain specifically intended for usein towing vehicles. Securelyfasten the cable or chain tothe towing hook provided.
WARNING
Use extreme caution when tow-
ing the vehicle.
Avoid sudden starts or erratic driving maneuvers which
would place excessive stress
on the emergency towing hook
and towing cable or chain. The
hook and towing cable or
chain may break and cause
serious injury or damage.
If the disabled vehicle cannot be moved, do not forcibly con-
tinue the towing. Contact an
authorized Hyundai dealer or
a commercial tow truck serv-
ice for assistance.
Tow the vehicle as straight ahead as possible.
Keep away from the vehicle during towing.

Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. 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 con-
tact 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 pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
A Genuine HYUNDAI air cleaner fil-
ter is recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transaxle fluid
(if equipped)
Automatic transaxle fluid should not
be checked under normal usage
conditions.
But in severe conditions, the fluid
should be changed at an authorized
HYUNDAI dealer in accordance with
the scheduled maintenance at the
beginning of this chapter.
✽ ✽
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 condition and you
should not judge the need to replace
the fluid based upon the changed
color.

Maintenance
Checking 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 neces-
sary. 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 fairly steep
grade. If the stroke is more or less
than specified, have the parking
brake adjusted by an authorized
HYUNDAI dealer.
Stroke : 6~8 “clicks’’ at a force of 44 lbs (20 kg, 196 N).
WASHER FLUID
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 flamma-
ble under certain circum-
stances. Do not allow sparks
or flame to contact the washer
fluid or the washer fluid reser-
voir. Damage to the vehicle or
occupants could occur.
Windshield washer fluid is poisonous to humans and
animals. Do not drink and
avoid contacting windshield
washer fluid. Serious injury or
death could occur.

water for at least 15 min-
utes and get immediate
medical attention. If elec-
trolyte gets on your skin,
thoroughly wash the
contacted area. If you
feel a pain or a burning
sensation, get medical
attention immediately.
Wear eye protectionwhen charging or work-
ing near a battery.
Always provide ventila-
tion when working in an
