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 transmission occurs,
check the transmission fluid level.
• Check automatic transmission 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).
WARNING
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.

Owner maintenance precautions
Improper or incomplete service may
result in problems. This section gives
instructions only for the maintenance
items that are easy to perform.
As explained earlier in this section, sev-
eral procedures can be done only by an
Authorized Kia Dealer with special tools.
✽
NOTICE
Improper owner maintenance during
the warranty period may affect warran-
ty coverage. For details, read the sepa-
rate Kia Warranty & Consumer
Information Manual provided with the
vehicle. If you're unsure about any serv-
icing or maintenance procedure, have it
done by an Authorized Kia Dealer.
WARNING- Maintenance
work
• Performing maintenance work on
a vehicle can be dangerous.You
can be seriously injured while per-
forming some maintenance pro-
cedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
Authorized Kia Dealer.
• Working under the hood with the
engine running is dangerous.It
becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Always remove all
loose or hanging clothing and all
jewelry before working on the
engine.

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach
normal operating temperature.
3. Turn the engine off and wait for a few
minutes (about 5 minutes) for the oil to
return to the oil pan.4. Pull the dipstick out, wipe it clean, and
re-insert it fully.
5. Pull the dipstick out again and check
the level. The level should be between
F and L.If it is near or at L, add enough oil to bring
the level to F.Do not overfill.
Use only the specified engine oil. (Refer
to “Recommended Lubricants” later in
this section.)
Have engine oil and filter changed by an
Authorized Kia Dealer according to the
Maintenance Schedule at the beginning
of this section.
WARNING - Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may be
hot enough to burn you.

ENGINE COOLING SYSTEM
The high-pressure cooling system has a
reservoir filled with a mixture of
antifreeze and water. 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 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 until
it 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
Changing coolant
Have coolant changed by an Authorized
Kia Dealer according to the Maintenance
Schedule at the beginning of this section.
• Use only soft (de-mineralized) water in
the coolant mixture.
• The engine in your vehicle has alu-
minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-
ing.
• DO NOT USE alcohol or methanol
coolant or mix them with the specified
coolant.
• Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.For mixture percentage, refer to the fol-
lowing table.
WARNING - 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 caus-
ing serious injury.
