OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized 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 deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the coolant level in thecoolant reservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires. Check if the front of the radiator
and condenser are clean and not
blocked with leaves, dirt or insects
etc. If any of the above parts are
extremely dirty or you are not sure
of their condition, take your vehicle
to an authorized Kia dealer.
While operating your vehicle:
Check for vibrations in the steeringwheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly turns slightly or “pulls” to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the operation of your transaxle occurs,
check the transaxle fluid level.
Check the reduction gear P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).

At least monthly:
Check the coolant level in thecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flash-
ers.
Check the inflation pressures of all tires including the spare.
At least twice a year
(i.e., every Spring and Fall):
Check the radiator, heater and air conditioning hoses for leaks or
damage.
Check the windshield washer spray and wiper operation. Clean
the wiper blades with clean cloth
dampened with washer fluid.
Check the headlight alignment.
Check the muffler, exhaust pipes, shields and clamps.
Check the lap/shoulder belts for wear and function.
Check for worn tires and loose wheel lug nuts.
At least once a year:
Clean the body and door drainholes.
Lubricate the door hinges and checks, and hood hinges.
Lubricate the door and hood locks and latches.
Lubricate the door rubber weather- strips.
Check the air conditioning system.
Inspect and lubricate the reduction gear linkage and controls.
Clean the battery and terminals.
Check the brake fluid level.

NORMAL MAINTENANCE SCHEDULE
The following maintenance services must be performed to ensure good emission control and performance. Keep
receipts for all vehicle emission services to protect your warranty. Where both mileage and time are shown, the fre-
quency of service is determined by whichever occurs first.
*1: When adding coolant, use only deionized water or soft water for your vehicle and never mix hard water in the coolant filled atthe factory. An improper coolant mixture can result in serious malfunction or motor compartment damage.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Cooling system
Check the cooling system compo-
nents, such as the radiator, coolant
reservoir, hoses and connections ,
coolant 3way valve, chiller for leak-
age and damage. Replace any dam-
aged parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
✽ ✽NOTICE - NHTSA Safety
Corrosion Alert
NHTSA has warned all vehicle own-
ers of all brands that they must main-
tain their vehicles in a manner which
will prevent brake hose and brake line
failures due to corrosion when such
vehicles are exposed to winter road
salt and related chemicals. While seri-
ous corrosion conditions typically only
manifest themselves as safety issues
after 7 years of vehicle use, the corro-
sion process starts immediately and
thus underbody cleaning maintenance
must commence from your vehicle's
first exposure to road salts and chem-
icals. NHTSA urges vehicle owners to
take the following steps to prevent
corrosion:
(Continued)(Continued)
1. Wash the undercarriage of your
vehicle regularly throughout the
winter and do a thorough washing
in the spring to remove road salt
and other de-icing chemicals.
2. Monitor the brake system for signs of corrosion by having regu-
lar professional inspections and
watching for signs of problems,
including loss of brake fluid,
unusual leaks and soft or spongy
feel in the brake pedal.
3. Replace the entire brake pipe assembly if you find severe corro-
sion that causes scaling or flaking
of brake components.

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 levelTurn the vehicle 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 con-
tinue turning counterclockwise to
remove it.
WARNING
Removing radiator
cap
Never attempt to remove the
radiator cap while the motor
compartment is operating or
hot. Doing so might lead to
cooling system damage and
could result in serious personal
injury from escaping hot
coolant or steam.
CAUTION - Radiator
/Inverter cap
Never attempt to remove theradiator or inverter cap whilethe motor is operating or hot.Doing so might lead to coolingsystem and motor damage.

Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F and L marks on the side
of the coolant reservoir when the
motor room is cool.
If the coolant level is low, add enough
specified coolant to provide protec-
tion against freezing and corrosion.
Bring the level to F, but do not over-
fill. If frequent additions are required,
see an authorized Kia dealer for a
cooling system inspection.
Recommended coolant
When adding coolant, use only
deionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
damage.
DO NOT USE alcohol or methanol coolant or mix them with the spec-
ified 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.
The cooling circuit of a vehicle equipped with a heat pump system
may freeze in extremely low tem-
perature when the concentration of
the antifreezing liquid is below
45%.
OPSE074002
WARNING- Cooling fan
Use caution when
working near the
blade of the cooling
fan. The electric
motor (cooling fan) is
controlled by coolant tempera-
ture, refrigerant pressure and
vehicle speed. it may some-
times operate even when the
vehicle is not running.

Maintenance
For mixture percentage, refer to the
following table.Changing the coolant
Have the coolant changed by an
authorized Kia dealer according to
the Maintenance Schedule at the
beginning of this chapter.
Put a thick cloth around the radiator
cap before refilling the coolant in
order to prevent the coolant from
overflowing into motor compartment.
