Solution

1. Preparation

Tools Required: Clean rag, funnel (optional), gloves
Ensure the vehicle is on a level surface and the engine is cool.
Wear gloves to protect your hands from fluid.

2. Locate Power Steering Fluid Reservoir

Open the hood and secure it with the hood prop.
Find the power steering fluid reservoir, typically located near the engine on the driver's side.
Clean the area around the reservoir cap with a clean rag to prevent contamination.

3. Check Fluid Level

Remove the reservoir cap or dipstick (if applicable) and wipe it clean with a rag.
Reinsert the cap/dipstick fully, then remove it again to check the fluid level.
Compare the fluid level against the "MIN" and "MAX" markings on the reservoir.

4. Refill Power Steering Fluid

If the fluid level is below the "MIN" mark, refill the reservoir with the specified power steering fluid (often Pentosin CHF 202 or similar).
Use a funnel if necessary to avoid spills.
Fill the reservoir to the "MAX" mark, but do not overfill.

5. Final Steps

Replace the reservoir cap securely.
Start the engine and turn the steering wheel from lock to lock to circulate the fluid and remove air bubbles.
Recheck the fluid level and top off if necessary.
