2011 KIA Optima air conditioning

What to do in an emergency
66
IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you will experience a loss of
power, or hear loud pinging or knocking,
the engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as itis safe to do so.
2. Place the shift lever in P (automatic 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 coming 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 cooling
fan is operating. If the fan is not run-
ning, 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 leaking from the radiator,
hoses or under the vehicle. (If the air
conditioning 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 broken
or engine coolant is leaking out, 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 tem-
perature has returned to normal. Then,
if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-
heating happens again, call an author-
ized KIA dealer for assistance.
CAUTION
Serious loss of coolant indicates
there is a leak in the cooling systemand this should be checked as soonas possible by an authorized KIAdealer.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
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.

Maintenance
67
At least monthly:
Check the coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
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 con- ditioning 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 drain holes.
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.
Check the power steering fluid level.
Inspect and lubricate automatic transaxle linkage and controls.
Clean the battery and terminals.
Check the brake/clutch fluid level.

Parking brake
Inspect the parking brake system includ-
ing the parking brake pedal and cables.
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.
