What to do in an emergency
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1. Pull off the road and stop as soon
as it is safe to do so.
2. Place the shift lever in P (Park, for
automatic transaxle vehicle) or
neutral (for manual transaxle vehi-
cle) and set the parking brake. If
the air conditioning is ON, turn it
OFF.
3. If engine coolant is running out
under the vehicle or steam is com-
ing 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 for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop.)
5. If engine coolant is leaking out,
stop the engine immediately and
we recommend that you call an
authorized HYUNDAI dealer for
assistance.
IF THE ENGINE OVERHEATS
While the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING
NEVER remove the
radiator cap or the
drain plug while the
engine and radiator
are hot. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the
first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.

6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
7. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call an
authorized HYUNDAI dealer for
assistance.
•Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked by an
authorized HYUNDAI dealer.
•When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
CAUTION
IF YOU HAVE A FLAT TIRE
Changing a tire can be danger-
ous. Follow the instructions in
this section when changing a
tire to reduce the risk of serious
injury or death.

Maintenance
Owner maintenance schedule
When you stop for fuel:
•Check the engine oil level.
•Check coolant level in the engine
coolant reservoir.
•Check the windshield washer fluid
level.
•Check for low or under-inflated
tires.
While operating your vehicle:
•Note any changes in the sound of
the exhaust or any smell of exhaust
fumes in the vehicle.
•Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
•Notice if your vehicle constantly
turns slightly or “pulls” to one side
when traveling on smooth, level
road.
•When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or
“hard-to-push” brake pedal.
•If any slipping or changes in the
operation of your transaxle occurs,
check the transaxle fluid level.
•Check the automatic transaxle
P (Park) function.
•Check the parking brake.
•Check for fluid leaks under your vehi-
cle (water dripping from the air con-
ditioning system during or after use
is normal).
At least monthly:
•Check coolant level in the engine
coolant reservoir.
•Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
•Check the inflation pressures of all
tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
•Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
