Maintenance
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving components which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
A Genuine Kia air cleaner filter is
recommended 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 compo-
nents, 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 mainte-
nance schedule.

Manual transaxle fluid
(if equipped)
Inspect the manual transaxle fluid
according to the maintenance sched-
ule.
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 maintenance at the begin-
ning of this section.
✽ ✽
NOTICE
Automatic transaxle fluid color is
basically red.
As the vehicle is driven, the auto-
matic transaxle fluid will begin to
look darker.
It is the normal condition and you
should not judge the need to replace
the fluid based upon the changed
color.
Dual clutch transmission Fluid
Inspect the dual clutch transmission
fluid according to the maintenance
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:

CAUTION- Transaxle fluids
The use of a non-specified fluid
could result in transaxle mal-function and failure.
Use only specified automatictransaxle fluid. (Refer to"Recommended lubricants andcapacities" in chapter 9.)

conditions” in this chapter.)
CAUTION- Air filter main-
tenance
Do not drive with the air clean- er removed; this will result inexcessive engine wear.
When removing the air cleaner filter, be careful that dust ordirt does not enter the airintake, or damage may result.

cities or on dusty rough roads for a
long period, it should be inspected
more frequently and replaced earlier.
When you replace the climate control
air filter, replace it performing the fol-
lowing procedure, and be careful to
avoid damaging other components.
