SymbolWarning Description and Action
Hyundai i30 Airbag Warning Light
Airbag
When the ignition or the engine start/stop button is switched to ON, the Hyundai i30 airbag warning light illuminates for approximately 6 seconds then goes off. A fault with the SRS (Supplemental Restraint System) is indicated by the light remain on. This may be a fault with the airbag or seat belt pretensioner system. Occasionally cables become loose under the passenger seat due to objects becoming lodged and pushed. Check all cables are firmly connected.
Hyundai i30 Brake Warning Light
Brake
When the ignition or the engine start/stop button is switched to ON, the Hyundai i30 brake warning light illuminates for approximately 3 seconds then goes off. The light remains on if the parking brake is applied. If the parking brake is fully released, it indicates that brake fluid levels are low.
Low brake fluid level
It's normal for brake fluid levels to fall over time as brake pads wear.
1. Find a safe place to stop and switch off the engine.
2. Check the brake fluid level in the brake fluid reservoir. On the side of the tank, the level should fall between the 'MIN' and 'MAX' marks.
3. Use only hydraulic brake fluid conforming to DOT 3 or DOT 4 specification.
4. Before removing the reservoir cap, clean the area around the cap. If debris falls into the reservoir tank, it will contaminate the fluid.
5. Add fluid ensuring you do not exceed the MAX mark.
6. Check for any leak. If the system is leaking fluid or if the warning light remains on, do not continue driving. Frequent additions of fluid may indicate a leak.

For the first generation of the Hyundai i30, the above issue is indicated by the following warning light:
Hyundai i30 Low brake fluid Warning Light
Hyundai i30 ABS Warning Light
ABS
When the ignition or the engine start/stop button is switched to ON, the Hyundai i30 ABS warning light illuminates for approximately 3 seconds then goes off. If the ABS (anti-lock braking system) warning light stays on, there is a fault in the system. This is often a sensor related malfunction. ABS is an addition to normal brake and the system detects when the wheels are beginning to lock. ABS pulsates the brakes very quickly and constantly adjusts pressure to apply the most brake force possible without locking the wheels. The normal braking system will still be operational without the assistance of the anti-lock brake system. Be warned however, there is a greater possibility of the wheels locking when under emergency braking.
Hyundai i30 EBD Warning Light
EBD
The illumination of both the ABS and BRAKE warning lights together indicate a fault with the Electronic Brake Force Distribution (EBD). EBD is an additional braking aid that regulates brake pressure on a per-wheel basis.
What to do
This is potentially a dangerous situation as brakes may not work as expected during sudden braking. Avoid high speed driving and abrupt braking and make your way immediately to a Hyundai workshop.
Note
With the ABS and BRAKE warning light on, along with EBD failure, other systems may fail to operate. these include:
• ABS (Anti-lock brakes)
• EPS (Power steering)
• Speedometer
• Odometer
• Tripmeter




Hyundai i30 Electronic Parking Brake (EPB) Warning Light
EPB
The Hyundai i30 EPB warning light comes on for around 3 seconds when the ignition switch of engine start/stop button are set to ON. If the warning light does not go off, there is a fault with the Electronic Parking Brake.
