If these two warning lights illuminate at the same time while driving, your vehicle may have a malfunction with the ABS and EBD system.
In this case, your ABS and regular brake system may not work normally. Have the vehicle checked by an authorized HYUNDAI dealer as soon as possible.
WARNING
If both ABS and brake warning lights are on and stay on, your vehicle’s brake system will not work normally. So you may experience an unexpected and dangerous situation during sudden braking. In this case, avoid high speed driving and abrupt braking. Have your vehicle checked by an authorized HYUNDAI dealer as soon as possible.
✽ NOTICE
If the ABS warning light or EBD warning light is on and stays on, the speedometer or odometer/tripmeter may not work. Also, the EPS warning light may illuminate and the steering effort may increase or decrease. In this case, have your vehicle checked by an authorized HYUNDAI dealer as soon as possible.
