2006 KIA Optima fuel

4. While holding the accelerator fully
depressed, turn the ignition switch to
the START position and hold it (a
maximum of 10 seconds) to discharge
the excess fuel.
If the engine starts, the engine speed
will increase suddenly; immediately
release the ignition key and the
accelerator.
If the engine has not yet started,
release the accelerator after cranking
the engine.
5. Without depressing the accelerator,
crank the engine until it starts (a max-
imum of 10 seconds).
If the engine fails to start when the
engine is warm:If the engine is unusually difficult to
restart when it is warm (fails to start
after repeated attempts without
depressing the accelerator):
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. While depressing the accelerator
pedal about halfway down, turn the
ignition switch to the START
position and hold it (a maximum of
10 seconds).
4. After the engine has started, let it idle
for about 10 seconds before driving.In some models, the starter may not
operate if:
• In an automatic transaxle, the shift lever
is NOT in P (Park) or N (Neutral).
• In a manual transaxle, the clutch
pedal is not fully depressed.
Excessive engine noise (from valve
tappets) may occur if the engine has not
been operated for an extended period.
The noise should stop after the engine has
reached normal operating temperature.
If the noise does not stop, have the vehicle
inspected by an Authorized Kia Dealer.

NORMAL OPERATIONP (Park)This position locks the transaxle and
prevents the front wheels from rotating.
Always come to a complete stop before
shifting into this position.
R (Reverse)Use this position to drive the vehicle
backward.N (Neutral)In this position, the wheels and transaxle
are not locked. The vehicle will roll
freely even on the slightest incline unless
the parking brake or service brakes are
applied.D (Drive)This is the normal forward driving
position. The transaxle will auto-
matically shift through a four-gear
sequence, providing the best fuel
economy and power.
4-9
WARNING
Shifting into P (Park) while the
vehicle is in motion will cause
the front wheels to lock and you
will lose driving control of the
vehicle.✻
NOTICE
The transaxle may be damaged if
you shift into P (Park) while the
vehicle is in motion.
WARNING
Do not use the P (Park)
position in place of the
parking brake when leaving
the vehicle. Always make
sure the shift lever is latched
in the P (Park) position so
that it cannot be moved
unless the lock release
button is pushed in AND the
parking brake is fully set.
Turn the ignition switch OFF
whenever you leave the
vehicle unattended. Never
leave the vehicle unattended
while the engine is running.
Unexpected and sudden
vehicle movement may occur
if these precautions are not
taken.
Never leave a child
unattended in a vehicle.
CAUTION
Always come to a complete stop
before shifting into or out of R
(Reverse). You may damage the
transaxle if you shift into R while
the vehicle is in motion, except as
explained in “Rocking the Vehicle”.

The tachometer pointer may move
slightly when the ignition switch is in the
ACC or ON position with the engine
OFF. This movement is normal and will
not affect the accuracy of the tachometer
once the engine is running.
FUEL GAUGEThe fuel gauge indicates the approximate
amount of fuel remaining in the fuel tank.
Fuel tank capacity: 65L (17 us gal.)
The fuel gauge is supplemented by a low
fuel warning light located in the

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.
