illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
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.
General information
Applies to: vehicles with tire pressure monitoring system
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 MMI while driving ® page 276. It also com-
pares the current tire pressures with the stored
tire pressures and gives a warning in the driver
information system if the tire pressure is differ-
ent from what is stored @ page 277.
The system does not detect if the stored tire
pressures match the recommended tire pres-
sures. You must store the tire pressures again in
each of the following situations > page 277:
— Each time the tire pressures change, for exam-
ple when the load in the vehicle changes
— After replacing a tire
~ If wheels with new wheel sensors are used
~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 extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, increas-
ing the risk of an accident.
—A tire with low pressure flexes more. This
heats the tire up too much. This could cause
the tread to separate and even cause the tire
to burst, increasing the risk of an accident.
~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.
— If tires are replaced, the sensors and valves
do not need to be removed or replaced. Only
replace the valve stem and, if necessary, the
valve and the wheel electronics. If you have
questions, see an 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 system complies with United States FCC
regulations and ISED regulations
> page 313.
Displaying tire pressures and temperatures
Applies to: vehicles with tire pressure monitoring system
Requirement: you must be driving the vehicle.
> Applies to MMI: Select on the home screen: VE-
HICLE > Settings & Service > Tire pressure
monitoring > Display tire pressure.
The current tire pressures are shown in green,
yellow, or red numbers:
— Green: the current tire pressure and the speci-
fied tire pressure are approximately the same.
~ Yellow: the current tire pressure is lower than
the specified tire pressure.
~ Red: the current tire pressure is much lower
than the specified tire pressure.
