How to Check and Add Transmission Fluid

Checking and adding transmission fluid to your 2012 Hyundai Sonata Hybrid is a relatively simple process. Here are the steps you need to follow:

  1. Make sure your vehicle is parked on a level surface and the engine is turned off.
  2. Locate the transmission fluid dipstick, which is usually labeled and located near the engine bay.
  3. Remove the dipstick and wipe it clean with a lint-free cloth or paper towel.
  4. Reinsert the dipstick fully and then remove it again to check the fluid level. The dipstick will have markings indicating the proper fluid level range.
  5. If the fluid level is below the recommended range, you will need to add transmission fluid. Use a funnel to avoid spills and carefully pour the fluid into the transmission fluid filler tube.
