NOTICE Do not use alcohol type antifreeze or plain water alone. When it is extremely cold, we recommend to use 60% solution for your Lexus, to provide protection down to about −50_C (−58_F). Do not use more than 70% solution for better coolant performance. Check the condition of the battery and cables.
