Hyundai Tucson: Electronic Stability Control (ESC) / Indicator lights
When the ignition switch is placed to the ON position, the ESC indicator light illuminates, then goes off if the ESC system is operating normally.
The ESC indicator light blinks whenever the ESC is operating.
If ESC indicator light stays on, your vehicle may have a malfunction with the ESC system. When this warning light illuminates have your vehicle checked by an authorized HYUNDAI dealer as soon as possible.
The ESC OFF indicator light comes on when the ESC is turned off with the button.
WARNING
When the ESC is blinking, this indicates the ESC is active: Drive slowly and NEVER attempt to accelerate. NEVER press the ESC OFF button while the ESC indicator light is blinking or you may lose control of the vehicle resulting in an accident.
CAUTION
Driving with varying tire or wheel sizes may cause the ESC system to malfunction. When replacing tires, make sure they are the same size as your original tires for this vehicle.
