2006 KIA Optima overheating

ENGINE TEMPERATURE
GAUGEThis gauge shows the temperature of the
engine coolant when the ignition switch
is ON.
If the gauge pointer moves beyond the
normal range area toward the H position,
it indicates overheating that may damage
the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to “Overheating” in the
Index.
WARNINGS AND
INDICATORSWARNING LIGHTS/
AUDIBLE INDICATORSCHECKING OPERATIONAll the warning lights, except the brake
warning light, are checked by turning the
ignition switch ON (you do not need to
start the engine). Any light that does not
come ON should be checked by an
Authorized Kia Dealer.
If the brake system warning light does
not come ON when the ignition switch is
in the START position, have the system
checked by an Authorized Kia Dealer.
After starting the engine, check to make
sure that all warning lights are OFF. If
any are still ON, this indicates a situation
that needs attention. When releasing the
parking brake, the brake system warning
light should go OFF.
PARKING BRAKE AND
BRAKE FLUID WARNINGPARKING BRAKE WARNINGThis light comes on when the parking
brake is applied with the ignition switch
in the START or ON position. The
warning light should go OFF when the
parking brake is released.LOW BRAKE FLUID LEVEL
WARNINGIf the warning light remains ON when
the parking brake is released, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains ON:
1. Drive to the nearest safe location and
carefully stop your vehicle.
2. With the engine stopped, check the
brake fluid level immediately and
add fluid as required.
All brake components should also be
checked immediately for fluid leaks.

MALFUNCTION
INDICATOR LIGHT
(IF EQUIPPED)The CHECK ENGINE or malfunction
indicator light is installed in your
vehicle’s instrument panel and responds
to signals from the vehicle’s On Board
Diagnostic (OBD -II) System. The OBD-
II System monitors the performance of the
vehicle’s Emission Control System
(ECS), which is designed to reduce the
amount of air pollutants in engine exhaust
to the levels required by government
regulations.
When you first start the engine, the check
engine light will illuminate briefly as a
system check to confirm that the OBD-II
System is operating properly. As the
engine starts, this light turns off.
However, if at any time the OBD-II
system detects a faulty signal or
determines that the ECS is not performing
to specification, the CHECK ENGINE
light will illuminate continuously or flash.
Continuously ON :If the CHECK ENGINE light comes ON
while driving and illuminates continuously,
a potential problem has been discovered in
the ECS or one of the exhaust system
components. Generally, the vehicle will
continue to be driveablebut it should
be checked by an Authorized Kia Dealer
as soon as possible. This condition is
unlikely to lead to engine damage unless
a decrease in vehicle power or poor
running conditions is immediately
apparent.
Flashing ON and OFF :If the CHECK ENGINE light begins to
flash ON and OFF, a more serious
problem with the ECS or exhaust system
component has been detected. If this
happens, and there is no degradation
to performance, the vehicle is still
driveable(avoid high speeds) but should
be checked by an Authorized Kia Dealer
at your earliest possible convenience. If
the flashing CHECK ENGINE light is
accompanied by a decrease in power or
poor running conditions, safely stop the
vehicle and immediately contact Kia
Roadside Assistance.
Note that the CHECK ENGINE light
will illuminate for a problem like a loose
or missing gas cap, but will not
illuminate as a result of low engine oil or
coolant, low automatic transaxle fluid or
engine overheating. The driver will be
alerted to these conditions by other
indicators on the instrument panel.

• If you have to use to the electri-
cal accessories that draw higher
power (vacuum cleaner, lights,
cooler, etc.) only use the power
outlet intermittently and with
greater caution.
• Long periods of the vehicle not
being started (with electrical
accessories plugged in) will dis-
charge the vehicle’s battery and
degrade the battery life.
• Cap the cover of power outlet
when not in use.
• Some electronic devices can
cause electronic interference
when plugged into a vehicle’s
power outlet. These devices may
cause excessive audio static and
malfunctions in other electronic
systems or devices used in your
vehicle.
✻
NOTICE
• Do not hold the lighter in
because it will overheat.
• Only a genuine Kia lighter
should be used in the cigarette
lighter socket. The use of plug-in
accessories (shavers, hand-held
vacuums and coffee pots, for
example) may damage the socket
or cause electrical failure.
• If the lighter does not pop out
within 30 seconds, remove it to
prevent overheating.

• 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.

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.

DRIVING YOUR VEHICLE
4-52AIR 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.• 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.

SPECIAL DRIVING
CONDITIONSHAZARDOUS DRIVINGWhen hazardous driving is encountered
because of water, snow, ice, mud, sand, or
similar hazard, follow these suggestions:
 Drive cautiously and allow extra
distance for braking.
 Avoid sudden movements in braking
or steering.
 When braking in vehicles without
anti-lock brakes, depress the brake
pedal with a controlled up-and- down
motion until the vehicle is stopped.
 When starting from a stop in snow,
mud, or sand, use second gear and
accelerate slowly to avoid spinning
the front wheels. Low gear may be
used, if necessary.
 Use sand, rock salt, tire chains, or
other non-slip material under the
front wheels to provide traction when
stalled on ice, snow, or mud.
ROCKING THE VEHICLEIf it is necessary to rock the vehicle to
free it from snow, sand, or mud, move
the shift lever of an automatic transaxle
from D (Drive) to R (Reverse) in a
repeat pattern while depressing the
accelerator gently. With a manual
transaxle, move the shift lever back and
forth from 1 (First) to R (Reverse).
Do not race the engine. If you are still
stuck after a couple minutes of rocking,
have the vehicle pulled out by a tow
vehicle to avoid engine overheating and
possible damage to the transaxle.
5-7
WARNING -
Downshifting
Downshifting into first gear with
a manual transaxle or into low
with an automatic transaxle
while driving on slippery
surfaces can cause an
accident. The sudden change in
tire speed could cause the tires
to skid. Be careful when
downshifting on slippery
surfaces.
✻
NOTICE
Prolonged rocking may cause
engine overheating, transaxle
damage or failure, and tire
damage.
