mount a run- at tire. Let only an authorized

and mount run- at tires.
The valve stems on your run- at tires have sensors that
are part of the Tire Pressure Monitor System (TPMS).
These sensors contain batteries which are designed
to last for 10 years under normal driving conditions. See
your dealer if you ever need to have a wheel replaced,
or if the sensors ever need replacement.Notice:Using liquid sealants can damage the
tire valves and tire pressure monitor sensors in your
run- at tires. This damage would not be covered
by warranty. Don’t use liquid sealants in your
run- at tires.
In ation - Tire Pressure

effectively.

you can get the following:
