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
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized Kia dealer should perform
the operation.
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The engine and inverter coolant should
be changed at the intervals specified in
the maintenance schedule.
Automatic transaxle fluid
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 fluid
Check 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 pedal and cables.

721
Maintenance
Brake discs, pads, calipers and
rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for fluid
leakage.
Exhaust pipe and muffler
Visually inspect the exhaust pipes, muf-
fler and hangers for cracks, deterioration,
or damage. Start the engine and listen
carefully for any exhaust gas leakage.
Tighten connections or replace parts as
necessary.
Suspension mounting bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine off,
check for excessive free-play in the
steering wheel.
Check the linkage for bends or damage.
Check the dust boots and ball joints for
deterioration, cracks, or damage.
Replace any damaged parts.
Drive shafts and boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if nec-
essary, repack the grease.
Air conditioning refrigerant
Check the air conditioning lines and con-
nections for leakage and damage.

BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination. If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings
and/or clutch disc (if equipped). If the
fluid level is excessively low, have the
brake system checked by an authorized
Kia dealer.
Use only the specified brake fluid. (Refer
to “Recommended lubricants and capac-ities” in section 8.)
Never mix different types of fluid.
In the event the brake system requires
frequent additions of fluid, the vehicle
should be inspected by an authorized Kia
dealer. When changing and adding brake fluid,
handle it carefully. Do not let it come in
contact with your eyes. If brake fluid
should come in contact with your eyes,
immediately flush them with a large
quantity of fresh tap water. Have your
eyes examined by a doctor as soon as
possible.
Brake fluid, which has been exposed to
open air for an extended time should
never be used as its quality cannot be
guaranteed. It should be disposed of
properly.
CAUTION - Brake fluid
Do not allow brake fluid to contact
the vehicle's body paint, as paintdamage will result.
CAUTION - Proper fluid
Only use brake fluid in brake sys- tem. Small amounts of improper flu-ids (such as engine oil) can causedamage to the brake system.

Maintenance
Checking the washer fluid level
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the parking brake
Check whether the stroke is within spec-
ification when the parking brake pedal is
depressed with 20 kg (44 lb, 196 N) of
force. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly steep grade.
WARNING - Windshield
fluid
Do not drink the windshield washer
fluid. The windshield washer fluid is
poisonous to humans and animals.
WARNING - Flammable
fluid
Do not allow the washer fluid to
come in contact with open flames
or sparks. The windshield washer
fluid clan is flammable under cer-
tain circumstances. This can result
in a fire.

RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality. The correct
lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.
*
1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econ-
omy by reducing the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure
in everyday driving, but in a year’s time, they can offer significant cost and energy savings.
*
3If the API service SM engine oil is not available in your country, you are able to use API service SL.
