1996 Toyota Camry Owners Manual - Page 154

S S Keep the bottom of your vehicle free from mud, etc. This not only lessens weight but also helps prevent corrosion. Keep your vehicle tuned-up and in top shape. A dirty air cleaner, improper valve clearance, dirty plugs, dirty oil and grease, brakes not adjusted, etc. all lower engine performance and contribute to poor fuel economy. For longer life of all parts and lower operating costs, keep all maintenance work on schedule, and if you often drive under severe conditions, see that your vehicle receives more frequent maintenance (For scheduled maintenance information, please refer to the separate "Owner's Manual Supplement/Maintenance Schedule"). ! CAUTION Never turn off the engine to coast down hills. Your power steering and brake booster will not function without the engine running. Also, the emission control system operates properly only when the engine is running. 148
