LEXUS WARNING LIGHTS

Lexus features numerous sensors and systems to ensure optimum performance of your vehicle. From time to time, some mechanical and electrical components may develop a fault or malfunction and this guide serves to help you understand what the warning light indicates, and the recommended next step to take.

The key Lexus warning lights are either Red or Amber, typically requiring some sort of action to be taken. Informational warning lights are either green or white and typically indicate a system is in use.

Red means stop as soon as it’s safe.
Amber means that action is required.

If you’re unsure about what course of action to take, or have any questions regarding the warning lights, please contact our 24/7 Lexus on Wheels service at 6631-1388 or 9672-6972.
