What is the Triangle with Exclamation Point – Triangle with exclamation point is a catch‑all warning symbol used by many automakers (Toyota, Honda, BMW, Hyundai, Nissan, etc.). It doesn’t point to one specific fault but alerts you to check the instrument panel for more details.
How It Works
- Triggered by sensors: The car’s diagnostic system detects irregularities.
- Appears with other alerts: Often accompanied by text messages or additional icons.
- Color matters:
- Amber/Yellow – Minor issue (e.g., low washer fluid, loose fuel cap, low tire pressure).
- Red – Serious fault (e.g., brake system, overheating, charging system).
- Flashing – Active system response (e.g., traction control working).
Common Causes
- Low tire pressure
- Loose fuel cap
- Door ajar while driving
- Low washer fluid
- Brake or stability control issue
- Engine or cooling system fault

What to Do When You See It

- Red light: Stop safely and do not continue driving until the issue is diagnosed.
- Flashing light: Note when it flashes; it may indicate traction or stability control is active.
- Scan codes: Use an OBD‑II scanner or visit a mechanic to read fault codes.
