What does exclamation mark mean in Lexus RX 350?
The exclamation mark inside a triangle on the Lexus RX 350 is the Master Warning Light, a general alert that something in the vehicle needs attention.

Master Warning Light: What it signals
This section explains the purpose of the light and the kinds of situations that can trigger it.
- General alert: The triangle with an exclamation point indicates a fault that may not have its own dedicated symbol. The onboard display will show a specific message describing what needs attention.
- Multiple potential causes: Brake system issues, low tire pressure (TPMS), stability/traction control alerts, or other engine-related warnings can trigger the Master Warning Light.
- Driver action recommended: When the light comes on, review the vehicle information display for the exact message. If the light is flashing or accompanied by other warning lights, treat it as urgent and seek service promptly.
In short, the Master Warning Light serves as a catch‑all prompt to check vehicle systems and follow the displayed guidance to determine the necessary action.
What to do when the light comes on
Follow these steps to identify the issue and decide how to respond safely.
- Check the information display for the exact message or code. Use the steering wheel controls or touch screen to read the warning text.
- Assess urgency: If the message relates to brakes, tires, or steering, pull over safely and inspect or call for assistance. If it indicates engine trouble, monitor performance and plan a service visit.
- Check tire pressures and TPMS: If a tire is underinflated, inflate to the recommended pressure listed on the door jamb placard. If TPMS indicates a problem with a tire, inspect for damage or leaks.
- Check fluid levels: Ensure brake fluid, engine oil, and coolant are at the proper levels. Top up only as recommended by the owner’s manual; seek service if levels are low or unclear.
- Observe other warning lights: If the engine check light, ABS, or traction control lights are also illuminated, a service diagnosis is warranted.
- Seek professional help: If you cannot determine the cause or if the vehicle feels unsafe to drive, contact a Lexus dealer or qualified mechanic for a diagnostic check.
These steps help you isolate whether the issue is tire-related, braking-related, or engine-related, while prioritizing safety.
