Tyre pressure monitoring system

Tyre pressure monitoring system TYRE PRESSURE MONITORING
SYSTEM (TPMS)
The TPM system provides a low
pressure warning and does not
re-inflate your tyres. Tyre pressures
should be checked regularly using an
accurate pressure gauge when cold.
The TPM system can NOT register
damage to a tyre. Regularly check the
condition of your tyres, especially if
the vehicle is driven off-road.
When inflating tyres, care should be
taken to avoid bending or damaging the
TPM system valves. Always ensure
correct alignment of the inflation head
to the valve stem.
Note: Non-approved accessories may interfere
with the system. If this occurs, TYRE
PRESSURE MONITORING SYSTEM FAULT is
displayed in the message centre.
Wheels fitted with a TPM system can be
visually identified by the external metal lock nut
and valve (1). All Jaguar non-TPM system
wheels have a rubber valve fitted (2).
TPMS OPERATION
The TPM system monitors pressure of the
tyres via sensors located in each wheel and a
receiver located within the vehicle.
Communication between sensor and receiver
is via Radio Frequency (RF) signals.
If the telltale light illuminates, you should stop
and check your tyres as soon as possible and
inflate them to the recommended pressure as
stated on the tyre pressure placard. If low
pressure warnings occur frequently, the cause
must be determined and rectified.
When driving through variable climatic
conditions the TPM system warnings may be
intermittent.
Your vehicle will also indicate a TPM system
malfunction by initially flashing and
subsequent continuous illumination of the
warning telltale. A text message will
accompany the system malfunction and will
display TYRE PRESSURE MONITORING
SYSTEM FAULT. The TPM system fault
sequence will be activated at every ignition
cycle until the fault is rectified. When a
malfunction occurs, the system may not be
able to detect or signal low tyre pressure as
intended.
TPM system malfunctions may occur for a
variety of reasons which may include other
radio frequency systems that could cause
interference or the installation of incompatible
replacement tyres on the vehicle.
The tyre pressure warning
comprises a yellow warning
telltale within the instrument panel
and the associated messages
within the message centre.
