Deflation Detection System; Tyre Pressure Monitoring - Vauxhall ASTRA Owner's Manual

Deflation Detection System

(DDS)
3
The deflation detection system
continuously monitors the speed of all
wheels while driving. If a tyre loses
pressure, it grows smaller and therefore
rotates more quickly than the other wheels.
If the system detects a difference in speed,
the control indicator w illuminates in red.
After tyre pressure is corrected or a tyre or
wheel is changed, the system must be
initialised by pressing the DDS button.

Tyre pressure monitoring

system
3
The tyre pressure monitoring system
continually checks the pressure and speed
of all four wheels while driving.
A pressure sensor is installed in each wheel.
The inflation pressures of the individual
wheels are transmitted to a controller,
where they are compared.
The current tyre pressures can be
displayed on the graphical information
display or the colour information display 3.
Deviating tyre pressures are displayed in
the form of messages on the information
display whilst driving.
