MAINTENANCE Power steering fluid level Check the level on the dipstick. The level should be in the "HOT" or "COLD" range depending on the fluid temperature. See page 173 for additional information. Exhaust system Look for cracks, holes and loose supports. If you notice any change in the sound of the exhaust or smell exhaust fumes, have the cause located and corrected immediately. (See engine exhaust cautions in Section 3-1.) DOES YOUR VEHICLE NEED REPAIRING? Be on the alert for changes in performances and sounds, and visual tip-offs that indicate service is needed. Some important clues are: S Engine missing, stumbling, or pinging S Appreciable loss of power S Strange engine noises S A fluid leak under the vehicle (However, water dripping from the air conditioning after use is normal.) S Change in exhaust sound (This may indicate a dangerous carbon monoxide leak. Drive with the windows open and have the exhaust system checked immediately.) S Flat-looking tires, excessive tire squeal when cornering, uneven tire wear S Vehicle pulls to one side when driving straight on a level road S Strange noises related to suspension movement S Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches floors, vehicle pulls to one side when braking S Engine coolant temperature continually higher than normal 150
