Tire Pressure Monitor System
(CTS-V)
The Tire Pressure Monitor (TPM) System uses radio
and sensor technology to check tire pressure levels.
If your vehicle has this feature, sensors are mounted
on each run-flat tire and wheel assembly. The TPM
sensors transmit tire pressure readings to a receiver
located in the vehicle once every 60 seconds while the
vehicle is being driven, and once every 60 minutes
if the vehicle is stationary for more than 15 minutes.
Using the Message Center, tire pressure levels can be
viewed by the driver. For additional information about
the message center operation and displays, see
Message Center (CTS-V) on page 3-52.
When a low tire pressure condition is detected, a low
tire warning light, on the instrument panel cluster,
comes on to warn the driver.
When the tire pressure
monitoring system warning
light is lit, one or more
of your tires is significantly
under-inflated.
You should stop and check your tires as soon as
possible, and inflate them to the proper pressure as
indicated on the vehicle’s tire information placard.
Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability. Each
tire, should be checked monthly when cold and set to the
recommended inflation pressure as specified in the
vehicle placard and owner’s manual.
The Tire and Loading Information label (tire information
placard) is attached, to either, the center pillar near
the driver’s door latch post or on the rear edge of the
driver’s side rear passenger door. The label shows
the size of your vehicle’s original tires and the correct
inflation pressure for your vehicle’s tires when they
are cold. See
Inflation - Tire Pressure on page 5-62 and
Loading Your Vehicle on page 4-33 for additional
information.
