may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . 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.
Description
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the tem -
perature and pressure in the tires . The data is
sent from these sensors to the control module by
radio frequency.
The tire pressure monitoring system shows the
current pressures and temperatures
of the tires
in the Infotainment
system while driving
¢
page 253. It
also compares the current tire
pressures with the stored tire pressures and
gives a warning if the tire pressure is different
from what is stored ¢
page 254.
The system does not detect if the stored tire
pressures match the recommended tire pres-
sures. You must store the tire pressures again
¢ page
254:
- every time the tire pressures change, for exam-
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new wheel sensors are used .
A
WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in-
flated to the correct pressure.
- Do not change the tire pressure when the
temperature
of the tire is high. This could
result in serious damage to the tire and
even cause the tire to burst, increasing the
risk of an accident.
-A tire with low pressure flexes more. This
heats the tire up too much. This could cause
Wheels
the tread to separate and even cause the
tire to burst, increasing the risk of an acci-
dent.
- The tire pressure monitoring system does
not warn about damage or defects in the
tire construction that could cause the tire to
burst, for example . Inspect your tires regu -
larly.
(D
Tips
- If tires are replaced, the sensors/valves
do
not need to be removed or replaced . Just re-
placed the valve stem and, if necessary, the
valve and the wheel electronics. If you have
questions , see your authorized Audi dealer
or authorized Audi Service Facility .
-An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors replaced by an authorized Audi
dealer or authorized Audi Service Facility.

The current tire pressures are shown in green or
as yellow numbers in the Infotainment
system:
- Green:
the current tire pressure and the speci-
fied tire pressure are approximately the same.
- Yellow:
the current tire pressure is too low
compared to the specified tire pressure .
The specified tire pressure is the last tire pres-
sure that was stored ¢
page 2 54 .
Note that the tire pressure also depends on the
temperature
of the tire. The tire pressure in-
creases as the engine becomes warmer while
driving .
