2006 KIA Optima check engine

POWER STEERING Power steering uses energy from the
engine to assist you in steering the
vehicle. If the engine is off or if the
power steering system becomes
inoperative, the vehicle may still be
steered, but it will require increased
steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power
steering system checked by an
Authorized Kia Dealer.
TILT STEERINGA tilt steering wheel allows you to adjust
the steering wheel before you drive. You
can also raise it to the highest level to
give your legs more room when you exit
and enter the vehicle.
To tilt the wheel, hold the steering wheel
and pull the lock release lever.
Move the steering wheel to a comfortable
level.

NOTICE
Never hold the steering wheel
against a stop (extreme right or left
turn) for more than five seconds
with the engine running. Holding
the steering wheel for more than
five seconds in either position may
cause damage to the power steering
pump.
If the power steering drive belt
breaks or if the power steering
pump malfunctions, the steering
effort will become greatly
increased.

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.
