tire pressure AUDI A7 2018 Owner's Manual

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

The current tire pressures are shown in green and
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
9 page 226 .
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.
A WARNING

.,. Correct the tire pressure if necessary. Refer to
the tire pressure Label for the recommended
tire pressure for your vehicle
c> page 215,
fig . 190 .
Only correct the pressure in tires
whose temperature is approximately the same
as the ambient temperature. If the tempera­
ture of the tire is higher than the ambient air
temperature, the tire pressure must be in­
creased approximately 3 PSI (0,2 bar) above
the value on the sticker .

Malfunctions
Applies to: vehicles with tire pressure monitoring syste m
-
If the Tire Pressure Monitoring System is not
avai lable, the
mm indicator light appears in the
driver information system. The
IE indicator light
also blinks for approximately one minutes each
time the ignition is switched on . The tire pressure
monitoring system cannot be selected in the In­
fotainment system. The fol lowing are examples
of situat ions that could cause a malfunction:
-If the message appears at the end of the adap­
tation phase, the system cannot detect the
wheels installed on the vehicle. This may resu lt
from one or more wheels being installed with­
out wheel sensors or with incompatible wheel
sensors.
-A wheel sensor or another component has
failed.
-Using snow cha ins can affect the function of
the system because of the shield ing effect of
the chains .
-The tire pressure monitoring system is not
available due to a malfunction.
-T ransmitters with the same frequency, such as
headphones or remote-control led dev ices, may
cause a temporary system malfunction due to
the strong electromagnetic field.

Notes on wheel changing
Please read the information ~ page 212, New
tires or wheels
if you are going to use a spare tire
which is different from the tires on your vehicle.
After you change a tire:
- Check the tire pressure on the spare tire im­
mediately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
ft lbs (120 Nm).
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire ,
they should be replaced before you check the
tightening torque.
Emergency assistance
- Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover.
Until then , drive with extra care and at reduced
speeds.
A WARNING
- If you are going to equip your vehicle with
tires or rims which differ from those which

Emerg enc y assis tance
There are some restrictions on the use of the
spare tire. The spare tire has been designed spe ­
cifically for your type of vehicle. Do not replace it
with the spare tire from another type of vehicle.
S pac e-s av ing sp are tir e*
The tire pressure must be 61 PSI (4.2 bar).
Remov ing th e spar e tire
.,. Fold the cargo floor up to the rear bench seat .
.,. Turn the handwheel counter-clockw ise and re-
move it .
.,. Remove the spare t ire.
Snow chains
Using snow chains on the spare tire is not perm it ­
ted due to technical reasons .
If you have to drive with snow chains and a front
tire fa ils, mount the spare t ire in place of a rear
tire . Install the snow cha ins on the rear tire that
you removed, and install that in place of the
front tire that failed.
A WARNING
-
- After installing a spa re t ire, the tire p res­
s u re must be checked as quickly as poss ible.
- Do not drive faster than SO mph (80 km/h)
with a spare tire. Driv ing faster than that in­
creases the risk of an a ccident.
- Avoid full-throttle accelerat ion, heavy b rak­
ing, and fast cornering, because this in­
creases the risk of an accident.
- Never dr ive using more than one spa re t ire,
because th is increases the r isk of an acci­
dent.
- Norma l tires o r winter tires m ust not be
mounted on the spare tire rim .
- Only use the co llapsible spare tire in emer­
gencies and dr ive very carefu lly, especially if
it is more than 6 years o ld .

Emergency situations
-Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity of
the hoist.
-Before driving over a workshop hoist, en­
sure that there is sufficient clearance be­
tween the hoist and low parts of the ve­ hicle.
Vehicle transport
Applies to: vehicles with air suspension
~ Note
When transporting the vehicle on a car carri­
er, train , ship or by other means, only tie the
vehicle down at the running surface of the
tires, which is the outer circumference. Secur­
ing the vehicle at the axle components, sus­
pension struts or towing eyes is not permitted
because the pressure in the air suspension
struts can change during transport. The vehi­
cle may not be secured sufficiently if this hap­
pens.
