Understanding the Importance of Dashboard Lights
Dashboard lights are not mere decorations; they are crucial indicators of your vehicle’s health and safety. They alert you to potential problems, ranging from minor inconveniences to critical mechanical failures that could compromise your safety or damage your vehicle. Ignoring these lights can lead to costly repairs and, in worst-case scenarios, dangerous driving conditions.

Decoding the Common Lexus LS 460 Dashboard Lights
Here’s a breakdown of the most common dashboard lights you’ll encounter in your Lexus LS 460, categorized for easy understanding:
1. Warning Lights (Immediate Action Required)
These lights indicate a serious issue requiring immediate attention. Ignoring these can be dangerous.
- Brake System Warning Light ( ! in a circle or “BRAKE” illuminated): Indicates a problem with the braking system. This could be low brake fluid, a parking brake engagement, or a more serious issue. Immediately pull over safely and check the brake fluid level. If the light remains on or the brakes feel spongy, do not drive the vehicle. Have it towed to a qualified mechanic.
- Engine Coolant Temperature Warning Light (Thermometer in a liquid): Indicates the engine is overheating. Pull over immediately, turn off the engine, and allow it to cool down. Check the coolant level and consult your owner’s manual or a mechanic. Continuing to drive can cause severe engine damage.
- Oil Pressure Warning Light (Oil can): Indicates low oil pressure. Stop driving immediately and turn off the engine. Check the oil level. If low, add oil. If the light persists, have the vehicle inspected by a mechanic. Low oil pressure can cause catastrophic engine failure.
- Charging System Warning Light (Battery icon): Indicates a problem with the charging system, such as a faulty alternator or battery. The battery may not be charging. Drive to a safe location and have the vehicle inspected. Avoid turning off the engine, as it may not restart.

- Check Engine Light (Engine icon): Indicates a problem with the engine or emissions system. Have the vehicle inspected by a mechanic as soon as possible. This light can indicate a wide range of issues, from a loose gas cap to serious engine problems.
2. Caution Lights (Requires Prompt Attention)
These lights signal a problem that requires attention, but not necessarily immediate action.
