  1. CHECK FLUID LEVEL 
    1. Keep the vehicle level.
    2. With the engine stopped, check the fluid level in the oil reservoir.

      If necessary, add fluid.

      Fluid: ATF DEXRON® II or III 

      NOTE: Check that the fluid level is within the HOT LEVEL range on the reservoir/reservoir cap dipstick.

      If the fluid is cold, check that it is within the COLD LEVEL range.

    3. Start the engine and run it at idle.
    4. Turn the steering wheel from the lock position to the other side of lock position several times to boost fluid temperature.

      Fluid temperature: 80°C (176°F) 

    5. Check for foaming or emulsification.

      If there is foaming or emulsification, bleed the air in the power steering system (See BLEEDING ).
