TEMPORARY USE SPARE WHEEL
AND TYRE CHANGE
If the temporary use spare wheel is fitted the
system will automatically recognise the change
in wheel positions. The n after approximately
ten minutes of drivin g above 25 km/h (18
mph), a message deta iling which tyre is
affected (e.g. FRONT LEFT) and TYRE 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 TYRE
PRESSURE MONITORING SYSTEM FAULT .
This TPM system 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 tyre
assembly. Always replace the temporary use
wheel before having TPM system faults
investigated. The fault may well be rectified
with the fitment of a fu lly operational full size
running tyre in lieu of the temporary use spare
wheel assembly.
TYRE PRESSURE MONITORING
UNAVAILABLE
If all four running wheels and tyres are changed
for a set that are not fitted with TPM system
sensors (e.g. a set of winter wheels and tyres),
the message TYRE PRESSURE MONITORING
UNAVAILABLE is displayed. TPM system
sensors must be fitted to the wheels and tyres
for the system to be able to warn of low tyre
pressures.
When sensors are fitted to the replacement
wheel and tyre set, the vehicle needs to be
driven until the TPM system recognizes the
sensors before TPM will be available ( TYRE
PRESSURE MONITORING AVAILABLE is
displayed).
TYRE CHANGING
Always have your tyres serviced or changed by
a qualified technician.
Care must be taken to avoid contact between
the bead of the tyre and the sensor during
removal and refitting of the tyre, otherwise the
sensor may become damaged and or
inoperable.
Valve stem seal, washer, nut, valve core
and cap should be repl aced at every tyre
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 torque
figures and associated 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 va lve retention nut.

the wheel:
Always adhere to the instructions
given on the temporary use spare
wheel warning label. Failure to
comply can be dangerous.
When a temporary use spare wheel is
fitted, drive with caution and replace
with the specified wheel and tyre as
soon as possible.
Do not fit more than one temporary
use spare wheel and ty re assembly at
one time.
The temporary use spare wheel must
be inflated to 4.2 bar (60 psi, 420 kPa)
and cannot be repaired.
Temporary use spare wheel,
maximum speed is 80 km/h (50 mph).
DSC must be on when the temporary
use spare wheel is in use.
LOCKING WHEEL NUTS
Note: A code number is stam ped on the side of
the locking nut. Ensure the number is recorded
on the Security Card supplied with the
literature pack. Quot e this number if a
replacement is require d. Do not keep the
Security Card in the vehicle.
TIGHTENING THE WHEEL NUTS
Using the wheel nut wrench, lightly tighten the
wheel nuts alternately using the sequence
shown in the illustration.
Lower the jack, then tighten the wheel nuts
fully, in the same se quence shown. Do not
overtighten by using foot pressure or extension
bars on the wheel nut wrench.
At the earliest opportunity have the wheel nuts
tightened with a torque wrench to 125 Nm
(92 lb.ft).
This torque must not be exceeded.
