330 SAFETY
NOTE:
It is particularly important for you to check the
tire pressure in all of the tires on your vehicle
monthly and to maintain the proper pressure.
The TPIS consists of the following components:

Receiver module

Four TPMS sensors (Single Rear Wheel
(SRW) applications)

Six TPMS sensors (Dual Rear Wheel (DRW)
applications)

Pressure display in the instrument cluster
The TPIS will display all four (Single Rear Wheel
(SRW) applications) or six (Dual Rear Wheel
(DRW) applications) tire pressure values in the
instrument cluster display.
If a system fault is detected, the instrument
cluster will display a "SERVICE TPM SYSTEM"
message for a minimum of five seconds and
then display dashes (- -) in place of the pressure
value to indicate which sensor is not being
received.
If the ignition switch is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the "SERVICE
TPM SYSTEM" message will no longer be
displayed, and a pressure value will display in
place of the dashes. A system fault can occur
due to any of the following:

Signal interference due to electronic devices
or driving next to facilities emitting the same
radio frequencies as the TPMS sensors.

Installing aftermarket window tinting that
contains materials that may block radio wave
signals.

Accumulation of snow or ice around the
wheels or wheel housings.

Using tire chains on the vehicle.

Using wheels/tires not equipped with TPMS
sensors.
