2018 AUDI A7 flat tire

a co .... N
" N .... 0 00 \,;J ' Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale .
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
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.
Description
Applies to: vehicles with tire pressure monitor ing system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
T he 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.
T he Tire Pressure Monitoring System shows the
current pressures and temperatures of the tires
in the Infotainment system
¢page 226. It also
compares the current tire pressures with the
stored tire pressures and gives a warning in the
driver information system if the tire pressure is
different from what is
stored ¢ page 226 .
Wheels
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
¢ page 226:
- 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.
_& 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 extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, in­
creasing 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 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 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 authori zed Audi Service Facility.
- For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see
