Tires. They’re your vehicle’s connection to the road. Under-inflated tires lower fuel economy, can affect handling, and can be a safety concern. The Acura RDX continuously monitors air pressure in each tire. With a push of a button, you can check real-time tire pressure anytime to maintain optimum performance. For optimal tire wear and performance, tire pressure should be checked regularly with a gauge. If the system detects a tire with significantly low pressure, it alerts you. And even allows you to see which tire is under inflated The Acura RDX helps you stay on top of tire pressure-- automatically.
