If there is a problem with the brake pedal while driving, emergency braking is possible by pulling up and holding the EPB switch. Braking is possible only while you are holding the EPB switch. However, braking distance will be longer than normal.
WARNING
Do not operate the parking brake while the vehicle is moving except in an emergency situation. It could damage the brake system and lead to a severe accident.
NOTICE
During emergency braking the Parking Brake Warning Light will illuminate to indicate that the system is operating.
NOTICE
If there is a noise or burning smell after using the emergency brake, have your vehicle checked by an authorized HYUNDAI dealer as soon as possible.
