Hyundai Sonata: Electronic Stability Control (ESC) / ESC OFF usage
When Driving
The ESC OFF mode should only be used briefly to help free the vehicle if stuck in snow or mud by temporarily stopping operation of the ESC to maintain wheel torque.
To turn ESC off while driving, press the ESC OFF button while driving on a flat road surface.
NOTICE
To prevent damage to the transmission:
- Do not allow wheel(s) of one axle to spin excessively while the ESC, ABS, and brake warning lights are displayed. The repairs would not be covered by the vehicle warranty. Reduce engine power and do not spin the wheel(s) excessively while these lights are displayed.
