Kia Optima: Electronic stability control (ESC) / ESC OFF usage

When driving

• ESC should be turned on for daily driving whenever possible.
• To turn ESC off while driving, press the ESC OFF button while driving on a flat road surface.

WARNING - Operating ESC

Never press the ESC OFF button while ESC is operating (ESC indicator light blinks).

If ESC is turned off while ESC is operating, the vehicle may slip out of control.

✽ NOTICE

• When operating the vehicle on a dynamometer, ensure that the ESC is turned off (ESC OFF light illuminated). If the ESC is left on, it may prevent the vehicle speed from increasing, and result in false diagnosis.
• Turning the ESC off does not affect ABS or brake system operation.
