Here's a more specific breakdown:
1. Open the hood.
2. Look for a small, rectangular or cylindrical container with a cap on top. It will typically be made of plastic and have a sticker indicating "Power Steering Fluid".
3. The reservoir is usually positioned near the firewall, on the driver's side. It might be close to the master cylinder for the brakes, or near the battery.
Note: This is a general location and might vary slightly depending on the specific model and year of your MR2. If you're having trouble finding it, you can always consult your owner's manual or a repair manual for your specific car.
