2006 KIA Optima engine

4-41
TCS ON/OFF MODEIn the TCS ON mode, the indicator in the
instrument cluster will not be illuminated.
The indicator will illuminate when the
ignition key is turned to the “ON”
position, but it should go off after 3
seconds. It means the TCS is in the stand-
by status and at the moment of the actual
operation of the TCS, the indicator will
blink.
To switch to TCS OFF mode, press the
TCS switch. System will be deactivated
and the TCS indicator in the instrument
cluster will illuminate.
If the TCS indicator stays on in the TCS
ON mode, take your car to your
Authorized Kia Dealer and have the
system checked.
✻
NOTICE
• The TCS ON mode is activated
automatically when the engine is
started.
 When the TCS is operating
properly, you may feel a slight
pulsation in the vehicle. This is
only the effect of brake control
and is not unusual.
 When the engine starts, your
may hear a “click” sound from
the engine compartment. This is
only the sound of the TCS being
checked.
 When moving out of mud or
fresh snow with the TCS ON,
pressing the accelerator pedal
may not cause the engine speed
to increase.

5. If dehumidified heating is desired,
turn the air conditioning system (if
equipped) ON.
• If cool air is desired at face level for
bi-level operation, set the mode
selection switch to the position.
• If the windshield fogs up, set the mode
selection switch to the position.
AIR CONDITIONING
SYSTEM OPERATING
TIPS:• If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time to
let hot air inside the vehicle escape.
• To help reduce moisture on the inside
of windows on rainy, humid days,
decrease the humidity inside the
vehicle by operating the air
conditioning system.
• During air conditioning system
operation, you may occasionally
notice a slight change in engine
speed at idle as the A/C compressor
cycles ON. This is a normal system
operating characteristic.
• Use the air conditioning system every
month if only for a few minutes.
• After air conditioning system use,
you may notice clear water dripping
(or even puddling) on the ground
under the passenger side of the
vehicle. This is a normal system
operating characteristic.
CAUTION
Continued climate control system
operation in the recirculated air
position may allow humidity to
increase inside the vehicle which
may fog the glass and obscure visi-
bility.

• The air conditioning system includes
a function that will automatically turn
the A/C compressor OFF if engine
coolant temperature approaches an
overheating level. A/C compressor
operation will resume once engine
coolant temperature returns to the
“normal” range. Also, the A/C
compressor is automatically turned
off for a few seconds when the
accelerator is fully depressed.
• When operating the air conditioning
system use the outside (fresh) air
position.
• Operating the air conditioning system
in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.

AIR CONDITIONING
(IF EQUIPPED)All Kia Air Conditioning Systems are
filled with environmentally friendly
R134a refrigerant which is not damaging
to the ozone layer.
1. Start the engine. Depress the air
conditioning switch.
2. Set the mode selection switch to the
face position.
3. Set the air intake control switch to
the outside air or the recirculated air
position (switch indicator ON).
4. Set the temperature control knob (or
switch) to the desired position.
5. Set the fan speed control knob (or
switch) to the desired speed.
6. Adjust the fan speed control knob (or
switch) and temperature control knob
to maintain maximum comfort.• If warmer air is desired at floor level
for bi-level operation, set the mode
selection switch to the position
and adjust the temperature control
knob (or switch) to maintain maximum
comfort.
• When maximum cooling is desired,
set the temperature control knob (or
switch)to the extreme left position
and set the air intake control switch
to the recirculated air position
(switch indicator ON), then set the
fan speed control knob to the highest
speed.
✻
NOTICE
When using the air conditioning
system with high outside air tem-
peratures, monitor the temperature
gauge closely while driving up long
hills or in heavy traffic. Air condi-
tioning system operation may cause
engine overheating. Continue to use
the blower fan but turn the air con-
ditioning system off if the tempera-
ture gauge indicates engine over-
heating.

If you don’t want the outside (fresh) air
position when operating in either of these
modes, you can turn off the system
operation by performing the following:
1. Make sure the engine is running or
the ignition switch is in the ON
position.
2. Turn the fan speed control knob to
the “0” position.
3. Turn the mode selection knob to the
defrost ( ) position.
4. Push the air intake control button
( ) at least 5 times within 3
seconds.
5. Then the indicator light on the air
intake control button ( ) will blink
3 times with 0.5 second intervals
between blinks.
If you want to return to the outside
(fresh) air position, repeat the procedure
above.

CAUTION
Do not use defrost position
during cooling operation in
extremely humid weather. The dif-
ference between the temperature of
the outside air and that of the
windshield could cause the outer
surface of the windshield to fog up,
causing loss of visibility. In this
case, set the mode selection knob to
the position and fan speed con-
trol knob to the lower speed.

DRIVING TIPS
5-2FUEL REQUIREMENTSYour new Kia Vehicle must use only
UNLEADED FUEL having an octane
rating of 87 or higher. Your new Kia is
designed to obtain maximum performance
with unleaded fuel. Unleaded fuel will
minimize exhaust emissions and spark
plug fouling.
GASOLINE CONTAINING
ALCOHOL AND METHANOLEthanol (also known as grain alcohol) is
a mixture of ethanol and gasoline
marketed as gasohol. Do not use gasohol
containing more than 10% ethanol.
Methanol (also known as wood alcohol)
is a mixture of gasoline and methanol
marketed as gasohol. Do not use gasoline
or gasohol containing methanol.
Either of these fuels may cause
driveability problems and damage to the
fuel system.
Discontinue using gasohol of any kind if
driveability problems occur.
Vehicle damage or driveability problems
may not be covered by the manufacturer’s
warranty if they result from the use of:
 Gasohol containing more than 10%
ethanol,
 Gasoline or gasohol containing
methanol, or
 Leaded fuel or leaded gasohol
✻
NOTICE
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter. Never add
any fuel system cleaning agents to
the fuel tank other than what Kia
has specified or the equivalent.
(Consult an Authorized Kia Dealer
for details.)
Leaded fuel will damage the engine
control system’s oxygen sensor and
affect the emission control system.
✻
NOTICE
Never use gashol which contains
methanol. Discontinue use of any
gashohol product which impairs
driveability.
