Solution

1. Preparation

Tools Required:
- Clean cloth or paper towel
- Funnel (if needed for fluid top-up)
Check that the vehicle is parked on a level surface and the engine is running.

2. Check Fluid Level

Remove the dipstick from the transmission (if equipped).
Wipe the dipstick clean with a cloth or paper towel.
Reinsert the dipstick fully into the tube and remove it again.
Check the fluid level against the markings on the dipstick. The level should be within the "Hot" range if the transmission is at operating temperature.

3. Add Fluid (if necessary)

If the fluid level is low, locate the transmission fluid fill plug.
Using a funnel, add the recommended transmission fluid (check the owner's manual for the specific type) through the fill plug until the fluid reaches the correct level.
Replace the dipstick or fill plug securely.
