your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue
to function properly.
Spare wheel or compact spare wheel
The spare wheel or compact spare wheel has no tire pressure sensor. When the spare or compact
spare wheel is mounted on the vehicle, the Tire Pressure Monitoring System (TPMS) indicator light will
flash in the instrument cluster display. The TPMS continues to monitor 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 battery life. The sensors are reactivated by driving the vehicle again.
WARNING
Incorrect tire pressure can cause sudden tire failure, loss of vehicle control and serious
personal injury.
x
Always check and correct air pressure in all 4 tires, particularly after changing,
exchanging, or repairing tires.
x
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.
x
When replacing tires or wheel rims on vehicles equipped with TPMS, always read and
heed all of the information and WARNINGS,
Tires and wheels
.
NOTICE
x
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.
x
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
x
Do not use “comfort valve caps.” They do not seal properly and can damage the sensors.
x
When changing or rotating the tires, be careful not to damage the valves or sensors.
x
The aluminum valves that are installed should be replaced after about 6 years of use due to
aging of 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 sensors can
be reused.
