Power Steering Fluid
The power steering fluid reservoir usually has a small dipstick attached to the cap or a full line. Remove the cap and check the fluid level. The level should not change more than the normal range on the stick. If you have to add fluid more than once or twice a year, then have the system checked for leaks. These systems are easily damaged if you drive while the fluid is very low. Another warning of low power steering fluid is a buzzing noise when you turn the steering wheel at slow speeds.
