SCHEDULEA qualified service technician should
perform these vehicle inspections at the
indicated intervals to ensure safe and
dependable operation.
Bring any problem to the attention of an
Authorized Kia Dealer as soon as
possible.WHEN REFUELING, CHECK:• Engine oil level
• Engine coolant level
• Brake and clutch fluid level
• Washer fluid level
AT LEAST MONTHLY• Tire inflation pressuresEVERY 6 MONTHS, CHECK:• Power steering fluid level
• Automatic transaxle fluid level
You can do the following scheduled
maintenance items if you have some
mechanical ability, a few basic tools and
if you closely follow the directions in
this manual.OWNER MAINTENANCE
PRECAUTIONSImproper 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, several
procedures can be done only by a qualified
service technician with special tools.
Improper owner maintenance during the
warranty period may affect warranty
coverage. For details, read the separate
Kia Warranty and Consumer Information
Manual provided with the vehicle. If
you’re unsure about any servicing or
maintenance procedure, have it done by
an Authorized Kia Dealer.
CAUTION
Be careful when checking your
engine coolant level. The engine
compartment will be hot and you
could be burned.
WARNING - Maintenance
Work
Performing maintenance work
on a vehicle can be dangerous.
You can be seriously injured
while performing some
maintenance procedures. If you
lack sufficient knowledge,
experience or the proper tools
and equipment to do the work,
have it done by a qualified
technician.

WARNING - Loose
Clothing/Jewelry
Working under the hood with
the engine running is
dangerous. It is even more
dangerous when you wear
jewelry, long hair or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while
working under the hood, make
certain that you pull hair back,
remove all jewelry (especially
rings, bracelets, watches, and
necklaces) and all neckties,
scarves, and similar loose
clothing before getting near the
engine or cooling fans.
WARNING - Engine
Cooling Fans
Because your engine cooling
fans are electrically controlled,
they will run if the ignition
switch is on, even if the engine
is not running. This could cause
serious injury. To prevent this,
be sure the ignition is off, unless
you must run the engine while
performing maintenance or an
inspection.

7-12ENGINE OIL AND OIL
FILTERChecking 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 a few
minutes for the oil to return to the oil
pan.
4. Pull out the dipstick, 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.
The distance between L and F on the
dipstick represents 0.85 US qt. (0.7 liter).
Use only the specified engine oil.(Refer to “Recommended Lubricants”
later in this section)
CHANGING THE ENGINE
OIL AND FILTERChange engine oil and filter according to
the Scheduled Maintenance earlier in this
section.
1. Warm the engine up for a few
minutes and then turn it off. Remove
the oil filler cap.
2. Drain the oil into a suitable container
after removing the oil filler cap and
drain plug.

WARNING - Engine Oil
 Continuous contact with
USED engine oil has caused
skin cancer in laboratory
mice. Protect your skin by
washing with soap and
water.
 Keep all engine oil out of the
reach of children.

3. Remove the engine oil filter with an
oil filter wrench.
4. Use a clean rag to clean the oil filter
mounting surface on the engine.
5. Apply a small amount of engine oil
to the new oil filter O-ring seal.6. Install the oil filter and tighten it.
(Refer to the oil filter caution label
for tightening instructions.)
7. Replace the drain plug tightly after
the oil has thoroughly drained.
8. Refill the engine with new oil to the
F mark on the dipstick. Do not
overfill.
9. Re-install the oil filler cap securely.
10. Start the engine and inspect around
the oil filter seal for leaks.
Stop the engine.
Check the oil level and fill to the F
mark, if necessary.
OIL CAPACITY
2400cc Engine
- Without filter change : 4.0 liters
- With filter change : 4.3 liters

2700cc Engine
- Without filter change : 4.5 liters
- With filter change : 4.8 liters
Use only the specified engine oil. (Refer
to “Recommended Lubricants” later in
this section)
CAUTION
Both the oil and engine are hot. Do
not burn yourself.✻
NOTICE
When installing the replacement oil
filter, do not allow the oil filter
gasket to remain on the oil filter
mounting surface. This will cause
oil leakage and engine damage.
Remove the old gasket completely
so that a new gasket will properly
seat and seal.
✻
NOTICE
• Follow these instructions
carefully. An improper oil filter
installation can cause oil leakage
and engine damage.
• Although oil filters may have the
same external appearance, their
internal designs differ
significantly. These filters are not
interchangeable. To avoid
potential engine damage, use only
the specified filter. Consult an
Authorized Kia Dealer.

MAINTENANCE
7-14ENGINE COOLING
SYSTEMThe cooling system is a high-pressure
type with a reservoir and is filled with
year-round antifreeze coolant 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
WARNING - Removing
Radiator Cap
 Never attempt to remove the
radiator cap while the engine
is operating. Doing so might
lead to cooling system
and/or engine damage and
could result in serious
personal injury from
escaping hot coolant or
steam.
 Turn the engine off and wait
until it has cooled. Even then,
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
operating, 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
serious injury.
