1. Understanding Tire Pressure Monitoring Systems (TPMS)

What are Tire Pressure Monitoring Systems (TPMS), and why are they essential for modern vehicles? Tire Pressure Monitoring Systems (TPMS) are electronic systems that monitor the air pressure inside vehicle tires, ensuring they are within the manufacturer’s recommended range. According to the National Highway Traffic Safety Administration (NHTSA), TPMS helps prevent accidents caused by underinflated tires, which can lead to blowouts and reduced vehicle control. These systems use sensors to measure tire pressure and temperature, transmitting this data to the vehicle’s central control unit. There are two main types of TPMS: direct and indirect. Direct TPMS uses physical pressure sensors inside each tire, while indirect TPMS uses the vehicle’s anti-lock braking system (ABS) to estimate tire pressure. Monitoring your Mercedes-Benz’s tire pressure not only enhances safety but also improves fuel efficiency and extends tire life.

• Direct TPMS: Uses pressure sensors in each tire to measure pressure and temperature.
