DRIVING TIPS D Always perform a maintenance inspection after each day of off−road driving that has taken you through rough terrain, sand, mud, or water. For scheduled maintenance information, refer to the "Owner's Manual Supplement / Scheduled Maintenance". WINTER DRIVING TIPS Make sure you have a proper freeze protection for engine coolant. Only use "Toyota Super Long Life Coolant" or similar high quality ethylene glycol based non −silicate, non −amine, non−nitrite, and non−borate coolant with long−life hybrid organic acid technology. (Coolant with long−life hybrid organic acid technology is a combination of low phosphates and organic acids.) See "Checking the engine coolant level" on page 413 for details of coolant type selection. For the U.S.A.-"Toyota Super Long Life Coolant" is a mixture of 50% coolant and 50% deionized water. This coolant provides protection down to about −35_C (−31_F). For Canada-"Toyota Super Long Life Coolant" is a mixture of 55% coolant and 45% deionized water. This coolant provides protection down to about −42_C (−44_F). NOTICE Do not use plain water alone. Check the condition of the battery and cables. Cold temperatures reduce the capacity of any battery, so it must be in top shape to provide enough power for winter starting. Page 450 tells you how to visually inspect the battery. Your Lexus dealer and most service stations will be pleased to check the battery charge level. 315
