How the TPMS Works on Vehicles

Model: (Various brands) Various
Part: Tire pressure warning light

Video tutorial

In this video, see how the TPMS system works: explained by a major name in the tyre industry, such as Continental. The contact with the ground of a car is delegated to the tyres, and if one of the tyres has too low pressure, it deforms, reducing the contact area with the ground in the centre.

Properly inflated tyres distribute the weight of the vehicle evenly, positively affecting fuel consumption; technical studies have shown that over 25% of drivers operate with inadequate tyre pressure. Since November 2014, all M1 category vehicles (up to 8 seats + driver) in the EU must be equipped with a tyre pressure monitoring system to improve driving stability and braking safety.

There is an indirect system that relies on tyre rotation via the ABS control unit, and once all tyres are checked, it is necessary to reset the system. The direct system uses sensors to inform the driver which tyre has lost pressure, also providing current pressure readings for immediate resolution.

Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat.
