Maintenance
Engine compartment precautions (Diesel engine)
The piezo injector operates at highvoltage (maximum 200v). Therefore,
the following accidents may occur.
- Direct contact with the injector or
injector wiring may cause electric
shock or damage your muscle or
nerve system.
- The electromagnetic wave from the operating injector may cause the arti-
ficial heart pacemaker to malfunction.
Follow the safety tips provided below, when you are checking the engine
room while the engine is running.
- Do not touch the injector, injector
wirings, and the engine computer
while the engine is running.
- Do not remove the injector connector while the engine is running.
- People using pacemakers must not go near the engine while the engine
is starting or running.
WARNING - Maintenance
work
Performing maintenance work on a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorized KIA dealer.
Working under the hood with the engine running is dangerous. It
becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while work-
ing under the hood, make certain
that you remove all jewelry (espe-
cially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose cloth-
ing before getting near theengine or cooling fans.WARNING - Diesel Engine
Never work on the injection system with the engine running or within30 seconds after shutting off the
engine. High-pressure pump, rail,
injectors and high-pressure pipes
are subject to high pressure even
after the engine stopped. The fuel
jet produced by fuel leaks may
cause serious injury, if it touches
the body. People using pacemakers
should not move more than 30cm
closer to the ECU or wiring harness
within the engine room while the
engine is running, since the high
currents in the electronic engine
control system produce consider-
able magnetic fields.

Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap iscorrectly replaced.
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. 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 contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage. Air cleaner filter
A Genuine KIA air cleaner filter is recom- mended when the filter is replaced.
Spark plugs (for gasoline engine)
Make sure to install new spark plugs of
the correct heat range.
Valve clearance
(for gasoline engine)
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 dealerin 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.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.
CAUTION
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.)

Maintenance
Changing the engine oil and filter
Have engine oil and filter changed by an
authorized KIA dealer according to theMaintenance Schedule at the beginningof this section.The high-pressure cooling system has a
reservoir filled with year round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level at least once a year, at thebeginning of the winter season, and
before traveling to a colder climate.
Checking the coolant level
WARNING
Used engine oil may cause skin irri- tation or cancer if left in contact
with the skin for prolonged periods
of time. Used engine oil contains
chemicals that have caused cancer
in laboratory animals. Always pro-
tect your skin by washing your
hands thoroughly with soap and
warm water as soon as possibleafter handling used oil.
ENGINE COOLANT
WARNING - Removing
radiator cap
Never attempt to remove the radi- ator cap while the engine is oper-
ating or hot. Doing so might leadto cooling system and engine
damage. Also, hot coolant orsteam could cause serious per-
sonal injury.
(Continued)
(Continued)
Turn the engine off and wait untilit 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 aresure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
Even if the engine is not operat- ing, do not remove the radiatorcap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.

Maintenance

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 and L marks on the side of the
coolant reservoir when the engine iscool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorized
KIA dealer for a cooling system inspec-tion.
Recommended engine coolant
Use only soft (distilled) water in the
coolant mixture.
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 specifiedcoolant.
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 percentage, refer to the fol-
lowing table.
