DRIVING TIPS WINTER DRIVING TIPS Make sure your coolant is properly protected against freezing. 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 559 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). 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 601 tells you how to visually inspect the battery. Your Lexus dealer and most service stations will be pleased to check the battery charge level. Make sure the engine oil viscosity is suitable for the cold weather. See page 558 for recommended viscosity. Leaving a heavy summer oil in your vehicle during winter months may cause harder starting. If you are not sure about which oil to use, call your Lexus dealer - they will be pleased to help. Check the electronic ignition connections or obvious damage. Keep the door locks from freezing.
