Tire Monitor - Introduction - Volvo S60 Owner's Manual

CAUTION
•
After inflating the tires, always reinstall
the valve cap to help avoid damage to
the valve from dirt, gravel, etc.
•
Use plastic valve caps only. Metal
caps could corrode and become diffi-
cult to remove.
WARNING
•
Incorrect inflation pressure could lead
to tire failure, resulting in a loss of con-
trol of the vehicle.
•
Tire monitoring systems cannot indi-
cate sudden tire damage caused by
external factors (e.g., a blowout) in
advance.

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
the following messages in the text window,
Tire pressure low Check rear

If two or more tires have low pressure or if the
system cannot determine which tire has low
pressure, a general text ( Tire pressure low
Check tires
) will be displayed.

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 pressure
table (see Tire inflation – pressure table
(p. 297)), the tire inflation pressure placard
located on the driver's side B-pillar (the
structural member at the side of the vehi-
cle, at the rear of the driver's door open-
ing) or consult your Volvo retailer.
