In case of an emergency
4. The coolant level should then bechecked. If the level in the reservoir is
low, look for leaks at the radiator hoses
and connections, heater hoses and
connections, radiator, and water
pump. If you find a major leak or anoth-
er problem that may have caused the
engine to overheat, do not operate the
engine until it has been corrected. Call
an authorized Kia dealer for assis-
tance. If you do not find a leak or other
problem, carefully add coolant to the
reservoir.If the engine frequently overheats, havethe cooling system checked and repairedby an authorized Kia dealer.
Jump starting Jump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting proce-
dures. If in doubt, we strongly recom-
mend that you have a competent techni-
cian or towing service jump start your
vehicle.✽ ✽ NOTICEUse only a 12-volt jumper system. You
can damage a 12-volt starting motor,
ignition system, and other electrical
parts beyond repair by use of a 24-volt
power supply (either two 12-volt batter-
ies in series or a 24-volt motor generator
set).
WARNING
- Removing
radiator cap
Do not remove the radiator cap
when the engine and radiator are
hot. Scalding hot coolant and steam
may blow out under pressure. This
could cause serious injury.
EMERGENCY STARTING
WARNING
- Battery
• Keep all flames or sparks away
from the battery. The battery pro-
duces hydrogen gas which may
explode if exposed to flame or
sparks.
 Do not attempt to jump start the vehicle if the discharged battery
is frozen or if the electrolyte level
is low; the battery may rupture or
explode.
WARNING
- Battery
Never attempt to check the elec-
trolyte level of the battery as this
may cause the battery to rupture or
explode causing serious injury.

Maintenance
OWNER MAINTENANCE Owner maintenance schedule The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized Kia dealer at
the frequencies indicated to help ensure
safe, dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labor, parts and
lubricants used.When you stop for fuel: Check the engine oil level.
 Check coolant level in coolant reser-voir.
 Check the windshield washer fluid level.
 Look 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 any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
 Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
eling on smooth, level road.
 When stopping, listen and check for strange sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
 If any slipping or changes in the oper- ation of your transaxle occurs, check
the transaxle fluid level.
 Check automatic transaxle P (Park) function.
 Check parking brake.
 Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-
mal).
At least monthly: Check coolant level in the coolantrecovery reservoir.
 Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
 Check the inflation pressures of all tires including the spare.At least twice a year (i.e., every Spring and Fall) : Check radiator, heater and air condi- tioning hoses for leaks or damage.
 Check windshield washer spray and wiper operation. Clean wiper blades
with clean cloth dampened with wash-
er fluid.
 Check headlight alignment.
 Check muffler, exhaust pipes, shields and clamps.
 Check the lap/shoulder belts for wear and function.
 Check for worn tires and loose wheel lug nuts.
WARNING
- Radiationcoolant
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns or
other serious injury.

7ENGINE COOLING SYSTEM The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
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 climate.Checking the coolant level
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine is
cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorized
Kia dealer for a cooling system inspec-
tion.
WARNING
- Removing
radiator cap
 Never attempt to remove the radi-
ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.
(Continued)
(Continued)
 Turn the engine off and wait untilit cools down. Use extreme care
when removing 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 counterclockwise to
remove it.
 Even if the engine is not operat- ing, do not remove the radiator
cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.

Maintenance
New automatic transaxle fluid should
be red. The red dye is added so the
assembly plant can identify it as auto-
matic transaxle fluid and distinguish it
from engine oil or antifreeze. The red
dye, which is not an indicator of fluid
quality, is not permanent. As the vehi-
cle is driven, the automatic transaxle
fluid will begin to look darker. The
color may eventually appear light
brown.✽ ✽NOTICEHave an Authorized Kia dealer inspect
or change the automatic transaxle fluid
according to the Scheduled
Maintenance at the beginning of this
section.Changing automatic transaxle
fluidHave automatic transaxle fluid changed
by an authorized Kia dealer according to
the Maintenance Schedule at the begin-
ning of this section.
Use only the specified automatic
transaxle fluid. (Refer to "Recommended
Lubricants" later in this section.)
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.
Body lubrication All moving points of the body, such as
door hinges, hood hinges, and locks,
should be lubricated each time the
engine oil is changed. Use a non-freez-
ing lubricant on locks during cold weath-
er.
Make sure the engine hood secondary
latch keeps the hood from opening when
the primary latch is released.
LUBRICANTS AND FLUIDS
WARNING
- Coolant
 Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
(Continued)
(Continued)
 Radiator coolant can severelyobscure 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 it's occupants could occur.
 Windshield washer fluid is poi- sonous to humans and animals.
Do not drink and avoid contacting
windshield washer fluid. Serious
injury or death could occur.
