DRIVING TIPS D Do not rest your foot on the brake pedal while driving. It can cause dangerous overheating, needless wear, and poor fuel economy. D To drive down a long or steep hill, reduce your speed and downshift. Remember, if you ride the brakes excessively, they may overheat and not work properly. See page 234. D Be careful when accelerating, upshifting, downshifting or braking on a slippery surface. The abrupt change in engine speed, such as sudden acceleration or engine braking, could cause the vehicle to spin or skid. D Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do not drive over 140 km/h (85 mph) unless your vehicle has high-speed capability tires. Driving over 140 km/h (85 mph) may result in tire failure, loss of control and possible injury. Be sure to consult a tire dealer to determine whether the tires on your vehicle are high-speed capability tires or not before driving at such speeds. D Do not continue normal driving when the brakes are wet. If they are wet, your vehicle will require a longer stopping distance, and it may pull to one side when the brakes are applied. Also, the parking brake will not hold the vehicle securely. WINTER DRIVING TIPS Make sure you have a proper freeze protection of engine coolant. Your coolant must contain ethylene-glycol type coolant for a proper corrosion protection of aluminum components. Use "Toyota Long Life Coolant" or equivalent. See "Checking the engine coolant level" on page 347 for instructions. 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. Cold temperatures reduce the capacity of any battery, so it must be in top shape to provide enough power for winter starting. Page 380 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 346 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 260
