Opening the fuel filler lid
The fuel filler lid must be opened
from inside the vehicle by pulling up
the fuel filler lid opener.
If the fuel filler lid does not open
because ice has formed around it,
tap lightly or push on the lid to break
the ice and release the lid. Do not pry
on the lid. If necessary, spray around
the lid with an approved de-icer fluid
(do not use radiator anti-freeze) or
move the vehicle to a warm place
and allow the ice to melt. 1.Stop the engine.
2.To open the fuel filler lid, pull the
fuel filler lid opener up.
3.Pull open the fuel filler lid (1).
4.To remove the cap (2), turn the fuel filler cap counterclockwise.
5.Refuel as needed.
Closing the fuel filler lid
1.To install the cap, turn it clockwise until it “clicks” one time. This indi-
cates that the cap is securely one
time tightened.
2.Close the fuel filler lid and push it in lightly and make sure that it is
securely closed.
✽ ✽

NOTICE
Tighten the cap until it clicks one
time, otherwise the fuel cap open
warning indicator light will illu-
minate.

WARNING - Refueling
Always remove the fuel cap
carefully and slowly. If the cap
is venting fuel or if you hear a
hissing sound, wait until the
condition stops before com-
pletely removing the cap.
If pressurized fuel sprays out, it
can cover your clothes or skin
and subject you to the risk of
fire and burns.OUB041024OUB041025

What to do in an emergency
86
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a
loss of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, you should:
1.Pull off the road and stop as soonas it is safe to do so.
2.Place the shift lever in P (automat- ic transaxle) or neutral (manual
transaxle) and set the parking
brake. If the air conditioning is on,
turn it off.
3.If engine coolant is running out under the vehicle or steam is com-
ing out from underneath the hood,
stop the engine. Do not open the
hood until the coolant has stopped
running or the steaming has
stopped. If there is no visible loss
of engine coolant and no steam,
leave the engine running and
check to be sure the engine cool-
ing fan is operating. If the fan is not
running, turn the engine off. 4.Check to see if the water pump
drive belt is missing. If it is not
missing, check to see that it is
tight. If the drive belt seems to be
satisfactory, check for coolant leak-
ing from the radiator, hoses or
under the vehicle. (If the air condi-
tioning had been in use, it is nor-
mal for cold water to be draining
from it when you stop).
5. If the water pump drive belt is bro- ken or engine coolant leaks, stop
the engine immediately and call
the nearest authorized Kia dealer
for assistance. 6.If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.
7.Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized Kia dealer for
assistance.
Serious loss of coolant indicates
there is a leak in the cooling system
and this should be checked as soon
as possible by an authorized Kia
dealer.
WARNING - Under the hood
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts.
WARNING - Radiatorcap
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of
the opening and cause serious
burns.

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 chapter.
✽ ✽
NOTICE
Automatic transaxle fluid color is
basically red.
As the vehicle is driven, the auto-
matic 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.
CAUTION - Specified
fluid
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 section 8.)

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level
ground.
2. Start the engine and allow it to reach normal operating tempera-
ture.
3. Turn the engine off and wait for a few minutes (about 5 minutes) for
the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and reinsert it fully. 5. Pull the dipstick out again and
check the level. The level should
be between F and L.
If it is near or at L, add enough oil to
bring the level to F.Do not overfill.
Use a funnel to help prevent oil
from being spilled on engine com-
ponents.
Use only the specified engine oil. (Refer to “Recommended lubricantsand capacities” in section 8.)
WARNING - Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.
CAUTION - Replace engine oil
Do not overfill with engine oil.
Engine damage may result.

If the coolant level is low, add enough
specified coolant to provide protec-
tion against freezing and corrosion.
Bring the level to F (MAX), but do not
overfill. If frequent coolant addition is
required, see an authorized Kia deal-
er for a cooling system inspection.
Recommended engine 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
engine damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol-
based coolant to prevent corrosion
and freezing.
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. For mixture percentage, refer to the
following table.

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
pressure.

Maintenance
Turn the engine off and wait until it
cools down. Use care when remov-
ing the radiator cap. Wrap a thick
towel around it, and turn it counter-
clockwise 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.
Changing the coolant
Have the coolant changed by an
authorized Kia dealer according to
the Maintenance Schedule at the
beginning of this section.
Put a thick cloth or fabric around the
radiator cap before refilling the
coolant in order to prevent the
coolant from overflowing into engine
parts such as the alternator.CAUTION- Removingradiator cap
Never attempt to
remove the radiator cap while the engineis operating or hot.Doing so might leadto cooling system andengine damage.
