Hyundai Tucson: Electronic Stability Control (ESC) / ESC operation

ESC ON condition

When the ignition switch is in the ON position, ESC and the ESC OFF indicator lights illuminate for about three seconds. After both lights go off, ESC is enabled.

When operating

When ESC is operating, the ESC indicator light blinks:

• When you apply your brakes under conditions that may lock the wheels, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal.
• If Cruise Control has been used when ESC activates, Cruise Control automatically disengages. Refer to the “Cruise Control (CC)” section in Chapter 7 (if equipped).
• When moving out of the mud or driving on a slippery road, the engine RPM (revolutions per minute) may not increase even if you depress the accelerator pedal all the way. This is to maintain the stability and traction of the vehicle and does not indicate a problem.
