Low tyre-pressure warning system
Zoom
Already present on the C5 and the C8, the low tyre-pressure warning function enhances the range of safety equipment present on the C4. This system measures the pressure of all four tyres. Each tyre is fitted with an emitter and a pressure sensor, which sends information to the central control unit.
When one of the tyres drops below its preset pressure level, a message immediately flashes up on the multifunction screen to warn the driver. At the same time, a buzzer sounds. In the event of a puncture, the “Stop” indicator will also come on. In this way, this feature detects any under-inflation that could have an adverse impact on the car’s stability and on the safety of the occupants.
In addition to enhancing safety, this function also encourages the driver to check tyres regularly and to correct inflation levels. These checks bring gains in terms of reduced road noise, fuel consumption and tyre wear.
