Here's why:
* Compatibility: Using the wrong fluid can damage your power steering system. Different fluids have different chemical compositions, and using an incompatible one could lead to leaks, corrosion, or even failure of the power steering pump.
* Performance: The correct fluid ensures optimal performance and longevity of your power steering system.
How to find the right fluid:
1. Consult your owner's manual: This will specify the exact type of power steering fluid required for your specific Highlander model and year.
2. Contact your Toyota dealer: They can advise you on the correct fluid and provide genuine Toyota parts.
3. Check the power steering reservoir: Often, the reservoir itself will indicate the type of fluid required.
Remember: Always use the manufacturer's recommended fluids for your vehicle. It's the best way to ensure the longevity and performance of your car's systems.
