Air cleaner filter
A Genuine Kia air cleaner filter is recom-
mended when the filter is replaced.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
Valve clearance (if equipped)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized Kia dealer should perform
the operation.
Cooling system
Check the cooling system components,
such as the radiator, coolant reservoir,
hoses and connections for leakage and
damage. Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transaxle fluid
(if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
Automatic transaxle fluid
(if equipped)
Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, the fluid should
be changed at an authorized Kia dealer
in accordance to the scheduled mainte-
nance at the beginning of this chapter.
✽ ✽
NOTICE
Automatic transaxle fluid color is basi-
cally red.
As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.
This is a normal condition and you
should not judge the need to replace the
fluid based upon the changed color.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake/Clutch (if equipped) fluid
Check the brake fluid level in the brake
fluid reservoir. The level should be
between “MIN” and “MAX” marks on the
side of the reservoir. Use only hydraulic
brake fluid conforming to DOT 3 or DOT
4 specification.
Parking brake
Inspect the parking brake system includ-
ing the parking brake lever and cables.
CAUTION - Specified fluid
The use of a non-specified fluid
could result in transaxle malfunc-tion and failure.
Use only specified automatictransaxle fluid. (Refer to“Recommended lubricants andcapacities” in section 8.)

ENGINE COOLANT
The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. 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 (MAX) and L (MIN) 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 (MAX), but do not overfill. If fre-
quent coolant addition is required, see an
authorized Kia dealer for a cooling sys-
tem inspection.
Recommended engine coolant
When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
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.
WARNING - Cooling fan
Use caution when work-
ing near the blade of the
cooling fan. The electric
motor (cooling fan) is
controlled by engine
coolant temperature, refrigerant
pressure and vehicle speed. It may
sometimes operate even when the
engine is not running.

Maintenance
For mixture percentage, refer to the fol-
lowing table.Turn the engine off and wait until it cools
down. Use care when removing the radi-
ator 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 counter-
clockwise to remove it.

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 pres-
sure.

CAUTION- Removing radi-
ator cap
Never attempt to remove
the radiator cap while the engine is operatingor hot. Doing so mightlead to cooling systemand engine damage.
