  • Locate the oil dipstick usually marked with a bright colored handle.
  • Pull out the dipstick, wipe it clean, reinsert it fully, and then pull it out again.
  • Check the oil level on the dipstick. It should fall between the “min” and “max” marks.
  • If it is below the “min” mark you need to add oil.

Remember, to use the recommended type and viscosity of oil for your vehicle as specified in your owner’s manual.

To perform a check of your coolant level, follow these steps:


  • Ensure that your engine has cooled down before attempting to open the radiator or coolant reservoir cap.
