Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. Sensors are mounted on each tire and
wheel assembly, except the spare tire. The TPMS
sensors monitor the air pressure in your vehicle’s
tires and transmit tire pressure readings to a
receiver located in the vehicle.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol located on the instrument panel
cluster. A Driver Information Center (DIC) message
to check the pressure in a specific tire will also
appear on the DIC display. The low tire pressure
warning symbol on the instrument panel cluster
and the CHECK TIRE PRESSURE message
on the DIC display will appear at each ignition
cycle until the tires are inflated to the correct
inflation pressure. For additional information and
details about the DIC operation and displays
see
DIC Controls and Displays on page 233 and
DIC Warnings and Messages on page 239 .
You may notice, during cooler weather conditions,
that the low tire pressure warning symbol and
the CHECK TIRE PRESSURE message will
display when the vehicle is first started and then
turn off as you start to drive the vehicle. This could
be an early indicator that the tire pressures are
getting low and need to be checked and inflated
to the proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and inflated to
the inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on
the vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
As an added
safety feature, your
vehicle has been
equipped with a tire
pressure monitoring
system (TPMS) that
illuminates a low tire
pressure telltale when
one or more of your
tires is significantly
under-inflated.
