1. Park the vehicle on a level surface.
2. Turn off the engine and allow it to cool down.
3. Locate the transmission fluid fill plug on the side of the transmission.
4. Remove the fill plug using a 17mm hex wrench.
5. Insert the funnel into the fill hole.
6. Pour the transmission fluid into the funnel, adding enough fluid to bring the level up to the full mark on the dipstick.
7. Remove the funnel and replace the fill plug.
8. Start the engine and allow it to run for a few minutes.
9. Check the transmission fluid level again and add more fluid if necessary.
