Hyundai Ioniq (AE): Electronic Stability Control (ESC) / ESC OFF usage

Hyundai Ioniq (AE) 2017-2022 Owner's Manual / Driving your vehicle / Braking System / 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 parking 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.
  • When operating the vehicle on a dynamometer, make sure the ESC is turned off (ESC OFF light illuminated).

Information

Turning the ESC off does not affect ABS or standard brake system operation.

    When the Engine Start/Stop button is placed to the ON position, the ESC indicator light illuminates, then goes off if the ESC system is operating normally.

    The Vehicle Stability Management (VSM) is a function of the Electronic Stability Control (ESC) system. It helps ensure the vehicle stays stable when accelerating or braking suddenly on wet, slippery and rough roads where traction over the four tires can suddenly become uneven.
