Solution

1. Preparation

Gather necessary tools and materials:
- Clean rag or paper towel to wipe the reservoir
- Funnel (if adding fluid)
Ensure the vehicle is on a flat surface.

2. Locate the Power Steering Fluid Reservoir

Open the hood and secure it.
Identify the power steering fluid reservoir; it is typically located near the front of the engine bay, on the driver’s side.
The reservoir cap is usually labeled with a steering wheel icon.

3. Check Fluid Level

Wipe the area around the reservoir cap with a clean rag to remove any dirt or debris.
Carefully unscrew the cap and set it aside.
Look inside the reservoir; the fluid should be between the minimum and maximum marks on the side of the reservoir.
If the fluid is low, proceed to the next step.

4. Add Power Steering Fluid (if necessary)

Use the recommended power steering fluid specified in the owner’s manual.
Using a funnel, carefully add fluid until it reaches the maximum level mark.
Do not overfill, as this can lead to foaming or leakage.

5. Replace Cap and Clean Up

Reinstall the reservoir cap securely.
Wipe any spilled fluid off the engine bay to prevent slipping and contamination.
Close the hood of the vehicle.
