Driving Your Vehicle
4-30
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 sys-
tem components. Generally, the vehicle will continue
to be driveable but it should be checked by an autho-
rized 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 immedi-
ately apparent. Malfunction Indicator
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 con-
firm 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 specifica-
tion, the CHECK ENGINE light will illuminate contin-
uously or flash.
