What to do in an emergency
To prevent compact spare tire
failure and loss of control pos-
sibly resulting in an accident:
•Use the compact spare tire
only in an emergency.
•NEVER operate your vehicle
over 80 km/h (50 mph).
•Do not exceed the vehicle’s
maximum load rating or the
load carrying capacity shown
on the sidewall of the com-
pact spare tire.
•Do not use the compact spare
tire continuously. Repair or
replace the original tire as
soon as possible to avoid fail-
ure of the compact spare tire.
WARNING
If you have a tire gauge, check the
tire pressure (see "Tires and
Wheels" in chapter 8 for tire pressure
instructions.). If the pressure is lower
or higher than recommended, drive
slowly to the nearest service station
and adjust it to the recommended
pressure. 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 changing
tires, secure the flat tire and return
the jack and tools to their proper stor-
age locations.
Check the tire pressure as soon
as possible after installing a spare
tire. Adjust it to the recommended
pressure.If any of the equipment such as the
jack, lug nuts, studs, or other equip-
ment is damaged or in poor condi-
tion, do not attempt to change the
tire and call for assistance.
Check and tighten the tire wheel lug
nuts after driving over 50km if tires
are replaced. Re-check the tire
wheel lug nuts after driving over
1,000km.Use of compact spare tires
(if equipped)
Compact spare tires are designed for
emergency use only. Drive carefully
on the compact spare tire and
always follow the safety precautions.
NOTICE
Your vehicle has metric threads
on the studs and lug nuts. Make
certain during tire changing
that the same nuts that were
removed are reinstalled. If you
have to replace your lug nuts
make sure they have metric
threads to avoid damaging the
studs and ensure the wheel is
properly secured to the hub. We
recommend that you consult an
authorized HYUNDAI dealer for
assistance.

What to do in an emergency
5. Unscrew the valve cap from the
valve of the flat tire and screw the
filling hose (3) of the sealant bottle
onto the valve.
6. Ensure that the compressor is
switched OFF.7. Plug the compressor power cord
(4) into the vehicle power outlet.
8. With the vehicle ON ( indica-
tor ON), switch on the compressor
and let it run for approximately
5~7 minutes to fill the sealant up
to proper pressure.(Refer to the
Tire and Wheels, chapter 8).The
inflation pressure of the tire after
filling is unimportant and will be
checked/corrected later.
Be careful not to overinflate the
tire and stay away from the tire
when filling it.
Securely install the sealant fill-
ing hose to the valve. If not,
sealant may flow backward,
possibly clogging the filling
hose.

What to do in an emergency
When towing your vehicle in an
emergency without wheel dollies:
1. Place the ignition switch in the
ACC position.
2. Place the shift lever in N (Neutral).
3. Release the parking brake.
Removable towing hook
1. Open the tailgate, and remove the
towing hook from the tool case.
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. Failure to place the shift lever in
N (Neutral) may cause internal
damage to the transmission.

Emergency towing
If towing is necessary, we recom-
mend you have it done by an author-
ized HYUNDAI dealer or a commer-
cial tow truck service.If a 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 at the front (or rear) of the
vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. 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 distance and at low speeds.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.Always follow these emergency tow-
ing precautions:
• Place the ignition switch in the ACC
position so the steering wheel is
not locked.
• Place the shift lever in N (Neutral).
• Release the parking brake.
• Depress the brake pedal with more
force than normal since you will
have reduced braking perform-
ance.
• More steering effort will be required
because the power steering system
will be disabled.
• Use a vehicle heavier than your
own to tow your vehicle.
• 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.

MaintenanceThe electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. As the engine coolant
temperature decreases, the electric
motor will automatically shut off. This
is a normal condition. If your vehicle
is equipped with GDI, the electric
motor for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable.The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan blades
of the cooling fan.
WARNING
Make sure the coolant cap is
properly closed after refilling
coolant. Otherwise the engine
could be overheated while driv-
ing.
1. Check if the coolant cap label
is straight In front.

Maintenance
Checking the parking brake
Foot type (if equipped)
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 20 kg (44 lb,
196 N) of force. 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 : 4~5 notch
Filter replacement
The air cleaner filter can be cleaned
for inspection using compressed air.
Do not attempt to wash or to rinse it,
as water will damage the filter.
If soiled, the air cleaner filter must be
replaced.OAE056014
PARKING BRAKE
To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:
•Do not use engine coolant or
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility
when sprayed on the wind-
shield and may cause loss of
vehicle control resulting in an
accident or damage to paint
and body trim.
•Do not allow sparks or flames
to contact the washer fluid or
the washer fluid reservoir.
Washer fluid may contain
alcohol and can be flamma-
ble.
•Do not drink washer fluid and
avoid contact with skin.
Washer fluid is poisonous to
humans and animals.
•Keep washer fluid away from
children and animals.

Maintenance
For best battery service
• Keep the battery securely mounted.
• Keep the battery top clean and dry.
• Keep the terminals and connec-
tions clean, tight, and coated with
petroleum jelly or terminal grease.
• Rinse any spilled acid from the bat-
tery immediately with a solution of
water and baking soda.
Information - For batteries
marked with UPPER and
LOWER
If your vehicle is equipped with a bat-
tery marked with LOWER (MIN) and
UPPER (MAX) on the side, you
should check the electrolyte level.
The electrolyte level should be
between LOWER (MIN) and UPPER
(MAX). When the electrolyte level is
low, add distilled (or de-mineralized)
water. (Never add sulfuric acids or
other electrolyte).
(continued)(continued)
Be careful not to spill distilled (or de-
mineralized) water over the battery
surface or other adjacent components.
Also, do not overfill the battery cells.
If not, it may corrode the battery or
other components. Finally, securely
close the cell cap. However, we recom-
mend you to contact an authorized
HYUNDAI dealer for better battery
service. i
