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 towing
If 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 shiftlever in N (Neutral) may cause inter-nal damage to the transaxle.

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 yourvehicle.
Use only a cable or chain specifi- cally intended for use in towingvehicles. Securely fasten thecable 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 cannot be moved, do not forcibly continue
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 belt
Inspect all parts related to the timing belt
for damage and deformation. Replace
any damaged parts immediately.
Vapor hose and fuel filler cap
The 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
hoses
Inspect 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 filter
A Genuine Hyundai air cleaner filter is
recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
Valve clearance
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
A qualified technician should perform the
operation.
Cooling system
Check the cooling system parts, 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 maintenance
schedule.

WASHER FLUID
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 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.
