What to do in an emergency
7. Connect the other end of the sec-
ond jumper cable to the black,
negative (-) chassis ground of
your vehicle (4).
Do not allow the jumper cables to
contact anything except the cor-
rect battery or jumper terminals or
the correct ground. Do not lean
over the battery when making
connections.
8. Start the engine of the assisting
vehicle and let it run at approxi-
mately 2,000 rpm for a few min-
utes. Then start your vehicle.
If your vehicle will not start after a
few attempts, it probably requires
servicing. In this event please seek
qualified assistance. If the cause of
your battery discharging is not
apparent, have your vehicle checked
by an authorized HYUNDAI dealer.Disconnect the jumper cables in the
exact reverse order you connected
them:
1. Disconnect the jumper cable from
the black, negative (-) chassis
ground of your vehicle (4).
2. Disconnect the other end of the
jumper cable from the black, neg-
ative (-) battery/chassis ground of
the assisting vehicle (3).
3. Disconnect the second jumper
cable from the red, positive (+)
battery/jumper terminal of the
assisting vehicle (2).
4. Disconnect the other end of the
jumper cable from the red, positive
(+) jumper terminal of your vehicle
(1).If your temperature gage 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)
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
call the nearest authorized
HYUNDAI dealer for assistance.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,
call an authorized HYUNDAI deal-
er for assistance.
Serious loss of coolant indi-
cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury.
WARNING
Your vehicle is
equipped with a
pressurized
coolant reserve
tank. NEVER
remove the
engine coolant
reservoir
tank/radiator cap or the drain
plug while the engine and radia-
tor are HOT. Hot coolant and
steam may blow out under pres-
sure, causing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the engine coolant reservoir
tank/radiator cap. Wrap a towel
or thick rag around it, and turn it
counterclockwise slowly to
release some of the pressure
from the system. Step back
while the pressure is released.
When you are sure all the pres-
sure has been released, contin-
ue turning the cap counter-
clockwise to remove it.

Maintenance
Owner Maintenance Schedule
When you stop for fuel:
• Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windshield washer fluid
level.
Check the 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 posi-
tion.
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 transmission
occurs, check the transmission
fluid level.
Check the intelligent variable trans-
mission (IVT) P (Park) function.
Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning 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 brake lights,
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.
At least twice a year:
(i.e., every Spring and Autumn)
Check radiator, heater and air con-
ditioning hoses for leaks or dam-
age.
Check windshield washer spray
and wiper operation. Clean wiper
blades with a clean cloth damp-
ened with washer a fluid.
Check headlamp alignment.
Check muffler, exhaust pipes,
shields and clamps.
Check the seat belts for wear and
function. 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.

Maintenance
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.
Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Intelligent Variable
Transmission (IVT) Fluid
(if equipped)
Intelligent Variable Transmission
(IVT) Fluid should not be checked
under normal usage conditions. But,
the Intelligent Variable Transmission
(IVT) Fluid should be changed under
severe usage conditions. We recom-
mend that the Intelligent Variable
Transmission (IVT) Fluid changed by
an authorized HYUNDAI dealer
according to the maintenance sched-
ule.
(Refer to "Maintenance Under
Severe Usage Conditions" in this
chapter.)
Intelligent variable transmission
(IVT) fluid color is basically light
amber.
As the vehicle is driven, the intelli-
gent variable transmission (IVT)
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.
NOTICE
The use of non-specified fluid
(even marked as compatible
with genuine) could result in
shift quality deterioration and
vibrations, and eventual trans-
mission failure.
Use only specified Intelligent
Variable Transmission (IVT)
fluid. (Refer to "Recommended
lubricants and capacities" in
chapter 8.)

The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season
and before traveling to a colder cli-
mate.Checking the Engine Coolant
Level
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between the F and the L marks on
the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring the
level to the F mark, but do not overfill.
If frequent additions are required, see
an authorized HYUNDAI dealer for a
cooling system inspection.
Recommended engine coolant
When adding coolant, use only dis-
tilled (deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory.
An improper coolant mixture can
result in severe malfunction or
engine damage.
The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent corrosion and freezing.
Do not use alcohol or methanol
coolant or mix them with the spec-
ified coolant.
