Wheels and Tires
R
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 SYSTEM
FAULT.
Temporary use spare wheel and tire
change
Should it be necessary to change a wheel
and tire with the temporary use spare,
then the system will automatically
recognise the change in wheel positions.
Then after approximately ten minutes of
driving above 25 km/h (18 mph) , a text
message TIRE 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 SYSTEM FAULT.
The 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 spare
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 wheel and tire
assembly.
If a tire needs to be changed
It is recommended that you should always
have your tires serviced by a Jaguar
Dealer.
If a TPMS is fitted, each wheel and tire
assembly, with the exception of a
temporary use spare is equipped with a
tire pressure sensor connected to the tire
valve stem.
In order to avoid damage to the sensor
the tires must be removed and refitted to
the road wheel in a specific manner. Care
must be taken to avoid contact between
the bead of the tire and the sensor during
removal and refitting of the tire, otherwise
the sensor may become damaged and or
inoperable.
Caution: Valve stem seal, washer, nut,
valve core and cap should be replaced
at every tire change. Valve stem seal,
washer and nut must be replaced if
valve retention nut is loosened. Sensor
units and nuts must be refitted using
correct torques and associated torque
profile. Damage to the vehicle may
result if these precautions are not
taken.
Sensors can be removed from the wheel
by the unscrewing of the valve retention
nut.
Replacement sensor fitment
procedure
A replacement sensor must be fitted to a
running wheel in order to be recognised
by the system. Recognition only occurs
when the vehicle is driven above 25 km/h
(18 mph) for approximately ten minutes.
