Solution

1. Preparation

Ensure the vehicle is on a level surface.
Gather necessary tools: gloves, a clean rag, and a funnel if adding fluid.

2. Access the Dipstick

Open the hood of the vehicle.
Locate the transmission dipstick, usually marked with a bright handle near the back of the engine compartment.

3. Check Fluid Level

Pull out the dipstick and wipe it clean with a rag.
Reinsert the dipstick fully and remove it again.
Check the fluid level against the markings on the dipstick; it should be within the "full" range.

4. Add Transmission Fluid (if necessary)

If the fluid level is low, use a funnel to add the recommended type of transmission fluid (Toyota ATF WS).
Add fluid in small increments and recheck the level until it is within the proper range.

5. Final Steps

Reinsert the dipstick securely.
Close the hood of the vehicle.
