Solution

1. Preparation

Tools Needed: Funnel, clean rag, transmission fluid (specific to Toyota RAV4), gloves.
Safety Warnings: Ensure the vehicle is on a flat surface and the engine is off before checking fluid levels.

2. Check Fluid Level

Warm Up the Engine: Start the engine and let it idle for a few minutes to warm up the transmission fluid.
Locate the Dipstick: Open the hood and find the transmission fluid dipstick, typically labeled and near the rear of the engine bay.
Remove and Clean: Pull out the dipstick and wipe it with a clean rag to remove any fluid.
Reinsert and Remove Dipstick: Fully insert the dipstick back into the tube and then remove it again to check the fluid level.
Assess Fluid Level: The fluid level should be within the “full” or “hot” markings on the dipstick.

3. Add Fluid if Necessary

Select Correct Fluid: Use the recommended transmission fluid for your RAV4 (check the owner's manual).
Add Fluid: If the fluid is low, use a funnel to add the transmission fluid slowly through the dipstick tube, checking the level frequently.
Recheck Level: After adding fluid, recheck the level to ensure it is within the correct range.
