Solution

1. Preparation

Tools Required:
- Clean rag or paper towel
- Funnel (if adding fluid)
- Transmission fluid (specifically for Volvo XC90; refer to owner's manual for specifications)
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Access the Dipstick

Sub-steps:
1. Open the hood and locate the transmission fluid dipstick (usually near the back of the engine).
2. Remove the dipstick and wipe it clean with a rag or paper towel.

3. Check Fluid Level

Sub-steps:
1. Reinsert the dipstick fully and remove it again.
2. Check the fluid level against the markings on the dipstick; it should be within the "Full" and "Add" marks.
3. If the fluid is low, proceed to the next step to add fluid.

4. Add Transmission Fluid

Sub-steps:
1. Use a funnel to avoid spills and add the appropriate transmission fluid through the dipstick tube.
2. Add fluid in small increments (1/4 quart), checking the level after each addition until it reaches the correct level.
3. Recheck the dipstick again to ensure the fluid level is correct.

5. Final Check

Sub-steps:
1. Start the engine and let it run for a few minutes.
2. Shift through all gears, allowing the transmission fluid to circulate.
3. Recheck the dipstick for fluid level again, ensuring it remains within the proper range.
