Engine Oil and Oil FilterChecking the Engine Oil Level1. 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.Maintenance7-14
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.
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.

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.
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.
RIO ENG CNA 7-1.qxd 7/29/05 5:16 PM Page 15

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
Without filter change : 3.2 L (3.38 US qt.)
With filter change : 3.4 L (3.59 US qt.)
Use only the specified engine oil. (Refer to
“Recommended Lubricants’’ later in this section.)
Engine 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.
Maintenance7-16
✻ ✻
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.

Checking the 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 full in the radiator
and between F (Full) and L (Low) on the coolant
reservoir dipstick when the engine is cool.
Check the coolant level using the dipstick attached to
the reservoir cap.
7-17
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.

If the coolant level is low, add enough specified
coolant to provide protection against freezing and
corrosion and to bring the level to F in the coolant
reservoir. Do not overfill. If frequent additions are
required, see an Authorized Kia Dealer for a cooling
system inspection.Changing CoolantChange coolant according to the Scheduled
Maintenance.
 Use only soft (de-mineralized) water in the coolant
mixture.
 The engine in your vehicle has aluminum engine
parts and must be protected by an ethylene glycol-
based coolant to prevent corrosion and freezing.
 DO NOT USE alcohol or methanol coolant and do
not 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 percentages, refer to the following table.Maintenance7-18

1. Turn the radiator cap counterclockwise and remove
it.
2. Loosen the radiator drain plug and drain the coolant
into a suitable container.
3. With the drain plug loose, flush the system with
running water.
4. Drain the system completely and retighten the drain
plug. Add the necessary amount of ethylene glycol-
based coolant and water to provide the required
protection against freezing and corrosion.
In extremely cold climates, add the necessary
amount of ethylene glycol-based coolant in
accordance with the instructions of the coolant
manufacturer.
5. Run the engine at idle with the radiator cap off.
Slowly add additional coolant if necessary.
6. At this point, wait until the engine reaches normal
operating temperature. Depress the accelerator two
or three times; then add coolant if required. Be
careful not to burn yourself.
7. Install the radiator cap. Inspect all connections for
leaks and recheck the coolant level in the reservoir.
Recheck again after a few days of driving and add
coolant as necessary.

Brakes and ClutchChecking Brake/Clutch Fluid LevelBrake Fluid Reservoir
Before adding fluid, thoroughly clean the area around
the reservoir cap to prevent brake fluid contamination.
If you add brake/clutch fluid, fill the brake/clutch fluid
reservoir to the MAX line. The brake/clutch fluid level
will drop with accumulated mileage. This is a normal
condition associated with brake/clutch lining wear.
Check the fluid level in the reservoir periodically; it
should be between MAX and MIN on the side of the
reservoir.
If the fluid level is excessively low, have the
brake/clutch system checked by an Authorized Kia
Dealer.
Use only the specified brake/clutch fluid. (Refer to
“Recommended Lubricants’’ later in this section.)
Do not mix different types of fluid.
Maintenance7-20
✻ ✻
NOTICE
In the event the brake/clutch system requires
frequent additions of fluid, the vehicle should be
inspected by an Authorized Kia Dealer.
