4-3. Do-it-yourself maintenance NOTICE n When recharging the battery Never recharge the battery while the engine is running. Also, be sure all accessories are turned off. n When replacing the battery Replace the battery with a battery of the same size. Installing a battery of a different size will prevent the cover from being properly installed over the battery. This may cause water to enter the engine compartment when it rains or the vehicle is washed, resulting in a malfunction. For more information about replacing the battery, contact your Lexus dealer. Washer fluid If any washer does not work or the warning message appears on the multi-information display, the washer tank may be empty. Add washer fluid. NOTICE n Do not use any fluid other than washer fluid Do not use soapy water or engine antifreeze instead of washer fluid. Doing so may cause streaking on the vehicle's painted surfaces. n Diluting washer fluid Dilute washer fluid with water as necessary. Refer to the freezing temperatures listed on the washer fluid tank. 510
