Tire pressure monitoring system
90
The TPMS may issue a warning if the under-
inflation becomes significant. When driving
through variable climatic conditions, the TPMS
warnings may be intermittent.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly.
Always check the TPMS malfunction telltale
after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.
A supplementary text message will accompany
the system indicator and will display TIRE
PRESSURE MONITORING SYSTEM FAULT.
TEMPORARY USE SPARE WHEEL
AND TIRE CHANGE
If the temporary use spare wheel is fitted the
system will automatically recognize the change
in wheel positions. Then after approximately
ten minutes of driving above 18 mph (25
km/h), a message detailing which tire is
affected (e.g. FRONT LEFT) and TIRE
PRESSURE NOT MONITORED will be displayed
accompanied by illumination of the warning
telltale and the corresponding block in the
vehicle graphic.
The warning telltale will initially flash and will
subsequently revert to continuous illumination.
Extended use of the temporary use spare wheel
will produce an additional text message TIRE
PRESSURE MONITORING SYSTEM FAULT.
This TPMS display sequence will be activated
at every ignition cycle until the temporary use
spare wheel is replaced by a fully operational
full size wheel and tire assembly.
Always replace the temporary use wheel before
having TPMS faults investigated. The fault may
well be rectified with the fitment of a fully
operational full size running tire in lieu of the
temporary use spare wheel assembly.
TIRE CHANGING
Always have your tires serviced or changed by
a qualified technician.
Care must be taken to avoid contact between
the bead of the tire and the sensor during
removal and refitting of the tire, or the sensor
may become damaged and or inoperable.
