Tire pressure monitoring system

Tire pressure monitoring system TIRE PRESSURE MONITORING
SYSTEM
TPMS provides a low pressure warning and
does not re-inflate your tires. Tire pressures
should be checked regularly, when cold,
using an accurate pressure gauge.
TPMS can NOT register damage to a tire.
Regularly check the condition of your tires,
especially if the vehicle is driven off-road.
When inflating tires, care should be taken to
avoid bending or damaging the TPMS 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, TIRE
PRESSURE MONITORING SYSTEM FAULT is
displayed in the message center.
Wheels fitted with TPMS 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 TPMS monitors pressure of the tires via
sensors located in each wheel and a receiver
located within the vehicle. Communication
between sensor and receiver is via Radio
Frequency (RF) signals.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label (if your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires).
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitoring
System (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires
is significantly under-inflated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. 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.
Please note that the TPMS is not a substitute
for proper tire maintenance and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
The tire pressure warning
comprises a yellow warning
telltale within the instrument panel
and the associated messages
within the message center.
