Hyundai Elantra (CN7): Electronic Parking Brake (EPB) / Parking brake warning light
Check the parking brake warning light by placing the ignition switch to the ON position (do not start the engine).
This light will be illuminated when the parking brake is applied with the ignition switch in the START or ON position. If the parking brake warning light remains on after the parking brake is released while engine is running, there may be a malfunction in the brake system. Immediate attention is necessary.
If at all possible, cease driving the vehicle immediately. If that is not possible, use extreme caution while operating the vehicle and only continue to drive the vehicle until you can reach a safe location.
This warning light illuminates if the ignition switch is set to the ON position and goes off in approximately 3 seconds if the system is operating normally.
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.
