2018 AUDI A8 fuel pressure

u. co .... N
" N .... 0 0 :c ' 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: 58 plus
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 Infota inment system
c:> page 303 . It also
compa res the current tire pressures with the
stored tire press ures and gives a warning in the
driver information system if the tire pressure is
different from what is stored
c:> page 304.
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures.
- Every time the tire pressures change, for exam-
ple when the load in the vehicle changes,
- after replac ing a tire, or
- if wheels with new wheel sensors are used,
you must store the tire pressures again
c:> page 304.
A WARNING
-The tire pressure mon itor ing system assists
the driver in monitoring tire pressures. The
dr iver 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.
T his cou ld result in serious damage to the
t ir e and even cause the tire to burst, in­
creasing the risk of an accide nt.
Wheels
-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 you of damage or defects in the
tire construct ion that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
@ For the sake of the environment
Low tire pressure increases fuel consumption
and tire wear.
(D Tips
-The pressure of the spare t ire* is not mon i­
tored.
- If tires are replaced, the sensors/va lves do
not need to be removed or replaced. Just re­
placed the valve stem and, if necessary, the
valve and the whee l electronics . If you have
questions, see an authorized Audi dealer or
authorized Audi Service Facility.
Displaying tire pressures/temperatures
Applies to: 58 plus
Requirement: the ignition must be switched on.
.. Select: the I CAR! funct ion button > Car systems
> Service & control > Tire pressure monitor >
Display tire pressure .
The current tire pressures are shown in green and
yellow numbers in the Infotainment system:
-Green: the current tire pressure and the spec i­
fied tire pressure are approx imately 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
c:> page 304 .
Note that the tire pressure also depends on the
temperature of the tire . The tire pressure in­
creases as the engine becomes warmer while
driv ing.
