Solution

1. Preparation

Gather necessary tools: gloves, lint-free cloth, funnel (if needed).
Ensure the vehicle is parked on a level surface and the engine is running to warm up the transmission fluid.

2. Check Fluid Level

Locate the Dipstick:
- Open the hood and find the transmission fluid dipstick, typically near the rear of the engine bay.
Remove and Clean the Dipstick:
- Pull the dipstick out slowly.
- Wipe the dipstick clean with a lint-free cloth to remove any fluid.
Reinsert and Check:
- Insert the dipstick back fully into its tube.
- Remove it again to observe the fluid level.
- The fluid level should be between the “Full” and “Add” marks.
Add Fluid if Necessary:
- If the fluid is low, use a funnel to add the recommended transmission fluid type (typically Toyota ATF WS).
- Add fluid gradually, checking the level frequently to avoid overfilling.
Finalize:
- Once the fluid is at the correct level, securely reinsert the dipstick.
- Close the hood of the vehicle.
