Tire Monitor - introduction
Tire Monitor uses the rotational speed of the tires in combination with signal analysis of the ABS sensor signals to determine if they are properly inflated.
When a tire is under-inflated, its diameter (and consequently also its rotational speed) changes. By comparing the individual tires with each other it is possible to determine if one or more tires are under inflated.
When low inflation pressure is detected or if the system is not functioning properly, Tire Monitor will light up the tire pressure warning light (
) (also referred to as a telltale) in the instrument panel and will display one of several messages in the text window, for example: Tire pressure low Check tires. Adjust the inflation pressure and recalibrate if necessary.
Note
If a malfunction occurs in the system, the tire pressure warning light will flash for approximately 1 minute and then remain illuminated. Tire press. syst Service required will be displayed.
Note
The system indicates low tire pressure but does not replace normal tire maintenance. For information on correct tire pressure, please refer to the tire inflation decal on the driver's door opening or consult your Volvo retailer.
