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.

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.

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.

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

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.

Power Steering (If Equipped)Checking the Power Steering Fluid LevelThe power steering fluid level should be checked
periodically.
With the engine off and the vehicle on level ground,
check the fluid level in the power steering reservoir; it
should be between the MAX and MIN reservoir
indicators.
MAXMIN
Before adding power steering fluid, thoroughly clean
the area around the reservoir cap to prevent power
steering fluid contamination.
If the level is low, add fluid to the MAX level.
In the event the power steering system requires
frequent addition of fluid, the vehicle should be
inspected by an Authorized Kia Dealer.
Use only the specified power steering fluid. (Refer to
“Recommended Lubricants’’ later in this section.)

✻ ✻
NOTICE
To avoid damage to the power steering pump, do
not operate the vehicle for prolonged periods with
a low power steering fluid level.
