2006 KIA Optima coolant temperature

STARTING THE ENGINE1. Make sure the parking brake is applied.
2.Manual Transaxle- Depress the
clutch pedal fully and shift the
transaxle into NEUTRAL. Keep the
clutch pedal depressed while
cranking the engine.
(For safety, the engine will not start if
the clutch pedal is not depressed fully
on manual transaxle equipped
models.)
Automatic Transaxle- Place the
transaxle shift lever in P (Park).
Depress the brake pedal fully.
You can also start the engine if the
shift lever is in the N (Neutral)
position.
3. Turn the ignition switch to START
and hold it until the engine starts (a
maximum of 10 seconds), then
release the key.In extremely cold weather, below 0ºF
(minus 18ºC), or after the vehicle has not
been operated for several days, let it
warm up without depressing the
accelerator.
Whether the engine is cold or warm, it
should be started without depressing the
accelerator.If the engine fails to start using this
procedure, attempt the following.
The engine fails to start when the engine
is cold (engine coolant temperature is
below 32ºF/0ºC):
A no start condition may be caused by an
engine that has become flooded (has
excessive fuel in the cylinders). If this is
the case, follow the starting procedure
below.
1. Make sure the parking brake is applied.
2.Manual Transaxle- Depress the
clutch pedal fully and shift the
transaxle into N (Neutral). Keep the
clutch pedal depressed while
cranking the engine.
Automatic Transaxle- Place the
transaxle shift lever in P (Park) or N
(Neutral). Depress the brake pedal
fully.
3. Depress the accelerator fully and
hold it.

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.

• 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.

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

 If you believe you may have gottenyour brakes wet, apply them lightly
while driving until normal braking
operation returns.WINTER DRIVING We recommend that you carryemergency equipment. Some things
you might include are tire chains, a
window scraper, windshield de-icer,
a bag of sand or salt, flares, a small
shovel and jumper cables.
 Make sure you have sufficient ethylene glycol coolant in the
radiator.
 Check the battery condition and cables. Cold temperatures reduce the
capacity of any battery, so it must be
in top shape to provide enough
winter starting power.
 Make sure the engine oil viscosity is suitable for cold weather.
 Check the ignition system for loose connections and damage.  Use antifreeze-formulated windshield
washer fluid and make sure you have
sufficient fluid for your trip. (Do not
use engine coolant antifreeze.)
 Do not use the parking brake if it might freeze. This is most likely to
happen after driving in slushy or wet
conditions and temperatures drop into
the freezing range. When parking,
shift to P (Park) with automatic
transaxle, or to 1 (First) or R
(Reverse) with a manual transaxle
and block the rear wheels.
SNOW TIRESWhen snow tires are used, select the size
and construction specified on the Tire
Pressure Label. It is strongly
recommended that snow tires be used on
all four wheels, or poor handling may
result. Snow tires should not be operated
at speeds exceeding 120 km/h (75 mph).
These tires should be inflated 4 psi (28
kPa, 0.3 kg/cm
2) above the recommended pressures shown on the Tire
Specification/Pressure Label, but inflation
should never exceed the maximum cold-
tire pressure shown on the tire sidewalls.
Do not install studded tires without first
checking local, provincial and municipal
regulations for possible restrictions
against their use.
WARNING - Snow Tire
Size
Snow tires should be
equivalent in size and type to
the vehicle’s standard tires.
Otherwise, the safety and
handling of your vehicle may be
adversely affected.

ROAD WARNINGHAZARD WARNING FLASHERThe hazard warning flasher serves as a
warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle. It
should be used whenever emergency
repairs are being made or when the vehicle
is stopped near the edge of a roadway.Depress the flasher switch with the
ignition switch in any position.
All turn signal lights will flash
simultaneously.
• The hazard warning flasher will
operate whether your vehicle is
running or not.
 The turn signals do not operate when
the hazard flasher is on.
 Care must be taken when using the
hazard warning flasher while the
vehicle is being towed. Local
regulations may prohibit using it in
this manner.
OVERHEATINGIf your temperature gauge indicates
overheating, if you experience a loss of
power, or if you hear a loud knocking or
pinging noise, the engine has probably
overheated. You should follow these
procedures if you experience any of
these symptoms.
1. Turn the hazard warning flasher on,
then drive to the nearest safe location
and stop your vehicle; set the
automatic transaxle in P (Park), or
shift the manual transaxle to neutral
and apply the parking brake.
2. Make sure the air conditioner is off.
3. If coolant or steam is boiling out of
the radiator, stop the engine, then
turn the ignition switch to the ON
position. Do not restart the engine.
The radiator cooling fan will
automatically operate with the
ignition switch in the ON position. If
the cooling fan does not operate, call
an Authorized Kia Dealer for
IN CASE OF EMERGENCY

assistance. If coolant is not boiling
out, allow the engine to idle and open
the hood to permit the engine to cool
gradually. If the temperature does not
go down with the engine idling, stop
the engine and allow sufficient time
for it to cool.
4. The coolant level should then be
checked. If the level in the reservoir
is low, look for leaks at the radiator
hoses and connections, heater hoses
and connections, radiator, and water
pump. If you find a major leak or
another problem that may have
caused the engine to overheat, do not
operate the engine until the problem
has been corrected. Call an
Authorized Kia Dealer for assistance.
If you do not find a leak or other
problem, carefully add coolant to the
reservoir.If the engine frequently overheats, have
the cooling system checked and repaired.
EMERGENCY STARTINGJUMP STARTINGJump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting
procedures on the next page. If in doubt,
we strongly recommend that you have a
competent technician or towing service
jump start your vehicle.

WARNING - Removing
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. This could cause
serious injury.
✻
NOTICE
Use only a 12volt jumper system.
You can damage a 12volt starting
motor, ignition system, and other
electrical parts by using a 24-volt
power supply (two 12-volt batteries
in series or a 24-volt motor
generator set).

7-15
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or
deteriorated hoses.
The coolant level should be full in the
radiator and between F (Full) and L
(Low) on the coolant reservoir tank
when the engine is cool.If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion and to
bring the level to F in the coolant
reservoir. Do not overfill. If frequent
additions are required, see an Authorized
Kia Dealer for a cooling system
inspection.
CHANGING COOLANTChange coolant according to the
Scheduled Maintenance.
• Use only soft (de-mineralized) water
in the coolant mixture.
• The engine in your vehicle has
aluminum engine parts and must be
protected by an ethylene glycol-
based coolant to prevent corrosion
and freezing.
• DO NOT USE alcohol or methanol
coolant and do not mix them with the
specified coolant.•Do not use a solution that contains
more than 60% coolant or less than
35% coolaut, which would reduce
the effectiveness of the solution.
For mixture percen-tages, refer to the
following table.
1. Turn the radiator cap counterclockwise
and remove it.
2. Loosen the radiator drain plug and
drain the coolant into a suitable
container.
