An i40 warning light needs a quick decision: should you stop now, or arrange a check soon? This guide follows the official 2018 Hyundai i40 VF warning-light and symbol data. Year, trim, engine and cluster type can change the lights shown on your car.
This page uses Hyundai’s verified official English warning-light route. Compare the exact symbol and the message shown in your own cluster before acting.

Quick color guide
- Red: stop safely and inspect oil, brakes, coolant, charging or steering first.
- Amber: find the cause and arrange service for engine, ABS, TPMS, EPB, ESC or safety warnings.
- Green or blue: usually an operating-state indicator, unless it flashes unexpectedly or stays on.
- This guide is for the 2018 gasoline VF baseline; diesel-specific warnings need their own manual.
14 i40 signals worth checking first
Some lights appear briefly during the normal start-up check. A light that remains on or returns while driving deserves the action in the last column.
| Type | Light | Meaning | Action |
|---|---|---|---|
| Stop | Low oil level or pressure | Stop, check oil, and do not continue if it remains | |
| Immediate | Drive belt or charging-system fault | Arrange inspection before discharge or overheating | |
| Braking | Parking brake, low fluid or brake fault | Slow down smoothly, stop and check braking | |
| Stop | Engine temperature is too high | Stop driving, let it cool and arrange service | |
| Safety | Airbag or pretensioner fault | Inspect it if it remains after 3–6 seconds | |
| Service | Engine control or fuel-supply fault | Have it checked soon; tow if it will not start | |
| Braking | Anti-lock braking-system fault | Restart safely; arrange service if it returns | |
| Tires | Low pressure or TPMS fault | Slow down and inspect all four tires | |
| Parking | Electronic parking-brake fault | Inspect it if it stays on after start-up | |
| Stability | Flashing can mean intervention; steady can mean a fault | Slow down on slippery roads and service a steady light | |
| Combined | One or more vehicle or assistance issues | Read the detailed cluster message first | |
| Safety assist | Feature disabled, sensor blocked or faulted | Clean the camera or radar area and recheck | |
| Steering | Steering assistance may be reduced | Stop safely if the wheel feels heavy | |
| Steering safety | Safety-steering status or fault | Check sensors and service a persistent light |

Red lights mean stop before troubleshooting
Oil pressure, charging, brake, coolant-temperature, airbag and steering warnings can have safety or mechanical consequences. If braking, steering or temperature changes, use roadside assistance or a tow.
Read engine, tire and brake warnings together
Engine, TPMS, ABS, EPB and ESC warnings describe different systems, but they all change the next drive. A recurring light, new vibration or changed pedal feel matters more than the amber color alone.
