318 SAFETY
The TPMS consists of the following
components:
Receiver module
Four Tire Pressure Monitoring System
sensors
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster
Tire Pressure Monitoring Warning Light
Tire Pressure Monitoring Low Pressure Warn-
ings
The TPMS Warning Light will
illuminate in the instrument cluster
a
n
d a chime will sound when tire
pressure is low in one or more of the
four active road tires. In addition, the
instrument cluster will display a "Tire Low"
message for a minimum of five seconds, an
"Inflate to XX" message and a graphic showing
the pressure values of each tire with the low tire
pressure values in a different color.
Tire Pressure Monitoring Low Pressure Warning
Should this occur, you should stop as soon as
po
ssible and inflate the tires with low pressure
(those in a different color in the instrument
cluster graphic) to the vehicle’s recommended
cold placard pressure value as shown in the
"Inflate to XX" message. Once the system
receives the updated tire pressures, the system
will automatically update, the pressure values
in the graphic display in the instrument cluster
will return to their original color, and the TPMS
Warning Light will turn off.
NOTE:
When filling warm tires, the tire pressure may
ne
ed to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off.
The vehicle may need to be driven for up to
20
minutes above 15 mph (24 km/h) in order
fo
r the TPMS to receive this information.
Service TPMS Warning
When a system fault is detected, the TPMS
Wa
rning Light will flash on and off for 75 seconds
and then remain on solid. The system fault will
also sound a chime. In addition, the instrument
cluster will display a "SERVICE TIRE PRESSURE
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 is cycled, this sequence will
re
peat, providing the system fault still exists. If
the system fault no longer exists, the TPMS
Warning Light will no longer flash, and the
“SERVICE TIRE PRESSURE SYSTEM” message
will no longer display, and a pressure value will
display in place of the dashes. A system fault
can occur due to any of the following:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors.
Installing some form of aftermarket window
tinting that affects radio wave signals.
