Spare wheel or compact spare wheel
The spare wheel or compact spare wheel has no tire pressure sen-
sor. When the spare or compact spare wheel is mounted on the vehi-
cle, the Tire Pressure Monitoring System (TPMS) indicator light will
flash in the instrument cluster display. The TPMS continues to moni-
tor the other 3 wheels.
Tire storage
If the tires do not move for an extended period of time, the sensors
will not transmit tire pressures to the system. This saves sensor bat-
tery life. When the ignition is switched on, the sensors transmit sig-
nals to the Tire Pressure Monitoring System.
WARNING
Incorrect tire pressure can cause sudden tire failure, loss of
vehicle control and serious personal injury.
Always check and correct air pressure in all 4 tires, particu-
larly after changing, exchanging, or repairing tires.
After that, always make sure that all 4 tires are inflated to the
correct tire pressure for the tires installed on the vehicle.
See the tire pressure label ⇒ Tire inflation pressure and the
Owner's Literature for recommended cold tire inflation pressure
and other important information.
When replacing tires or wheel rims on vehicles equipped with
TPMS, always read and heed all of the information and WARN-
INGS ⇒ Tires and wheels.
NOTICE
The wheel electronics are attached to special aluminum valves
on the wheels. These valves are screwed on rigidly. Never bend
the valves “into position” when checking and adjusting tire
pressure.
Missing tire air valve caps could result in damage to the
valves, as well as to the sensors on the Tire Pressure Monitoring
System. Therefore, make sure your valve caps conform to the
specifications of those originally installed on the vehicle and
that they are always tightly and properly screwed on to the
valves. Do not use metallic valve caps.
Do not use “comfort valve caps”, as these do not seal proper-
ly and could therefore cause damage to the sensors.
When changing or rotating the tires, be careful not to damage
the valves or sensors.
The aluminum valves that are installed should be replaced
after about 6 years of use because of aging in the rubber seals.
The valves can be replaced when a tire is changed. Do not reuse
aluminum valves after they are removed. They must be replaced.
The tire pressure sensor can be reused.
