RAW system description
WARNING: This page is about a different car, the 2009 MINI Cooper and 2008 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.
RAW measures the wheel speeds on all four wheels, using the wheel speed sensors of the ABS/ASC or ABS/DSC system. It compares the wheel speeds of the diagonally opposite wheels and of the average speed.
In the event of a drop in tire pressure, the dynamic diameter of a wheel will change, leading to a changed wheel speed.
A drop in tire pressure of 30 ± 10 % can be detected on all wheels from about 15 km/h (10 mph) up to the vehicle's top speed.
If this value is exceeded, the driver will be warned via the instrument cluster as follows:
WARNING CHART
| Loss of tire pressure | Warning |
|---|---|
| Loss of tire pressure of 30 ± 10 % | Red LED Text: "Tyre failure" Gong: yes The vehicle is not to be driven faster than 80 km/h (50 mph).
NOTE:
A cautious driving style with moderate forward and transverse acceleration will help to prolong the service life of the defective tire.
