Locate the dipstick and check the level in the same manner as described above. In this case, the hash marks on the stick indicate one pint. On most vehicles transmission fluid should be changed about every 30,000 miles. Check the belts. Check the wiper blades.
Good visibility is especially important for highway driving.
If the blades are badly worn, replace them before taking a long trip. Wipers should usually be replaced once a year. Don't forget to check the rear wiper if you have one. Top off the wiper fluid if necessary. Check the tire pressure.
