Tire pressure monitoring system
(J_) General notes
Each tire, incl uding the spare (if provided),
should be checked month ly when co ld and inflat­
ed to the inf lation pressure recommended by the
ve hicle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a d ifferent s ize tha n the s ize indicated on
the veh icle placa rd or t ire inflation pressure la­
be l, you s hou ld determine the prope r tir e infla­
tion pressure fo r th ose tires).
As an added safety feature, your ve hicle has been
equ ipped w ith a t ire pressu re monito ring system
(TPMS) that ill uminates a low tire p ress ure tell­
tale whe n one or more of yo ur t ires is sign ificant ­
l y unde r-infla ted. Accord ingly, whe n the low tire
p ressure tellta le illuminates, yo u should stop and
check your tires as soon as possible, and inflate
them to the proper press ure. D riving on a signifi ­
cantly under-inflated tire causes the tire to ove r­
h eat and can lead to t ire failure. Under-inflation
a lso reduces fuel efficiency and ti re tread life,
and may affect the veh icle's handling and stop­
p ing ability .
P lease note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib il ity to ma inta in correct tire pressure,
even if u nder-inflation has not reached t he leve l
to tr igger illum inat io n of t he TPM S low tire p res ­
sure telltale.
Your veh icle has also been equ ipped w ith a TPMS
malfunct ion ind icator to indicate when the sys­
tem is not operat ing properly. The TPMS ma l­
f u nction ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system det ects a
mal function, the te lltale wi ll flash fo r approxi ­
mate ly one mi nute and then remain continuous ly
illum inated. This sequence will continue upon
subseq uent ve hicle start-ups as long as the ma l­
function ex ists .
W hen t he malfunctio n indicator is ill uminated,
the system may not be ab le to detect or signa l
low t ire press ure as intended. TPMS ma lfunctions
may occur for a var iety of reasons, including the
Wheels
insta llation o f replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning p roperly . Always check the
TPMS ma lfunction te lltale after replac ing one or
more tires or wheels on you r vehicle to ensure
t h at the rep lacement or a lternate tires a nd
wheels allow t he TPMS to continue to function
prope rly.
If the Tire Pressure Monitoring System
indicator appears

The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
U sing the ABS se nsors, the t ire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and v ibration characterist ics of the ind ividu­
al tires. If the pressu re changes in one o r more

Tire pressure monitoring
system
ill General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tir e inflation pr essure la­
bel, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
( T PMS) that illuminates a low tire pressure tell­
tale when one or more of you r tires is significant­
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi­
cant ly under-inflated t ire causes the tire to over­
heat and can lead to tire failur e. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping ability.
..,.

Cl 00 .-< N r-­N .-< 0 r-­Vl 00
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 while driving
¢ page 264. 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 264 .
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 264:
- 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

Emergency assistance
{QJ Note
When removing or installing the wheel, the
rim could hit the brake rotor and damage the
rotor. Work carefully and have a second per­
son help you.
(D Tips
- When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way
¢ page 278.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Unidirectional tires
A unidirectional tire profile is identified by arrows
that point in the running direction on the tire
sidewall. You must always adhere to the speci­
fied running direction. This is necessary ensure
the tire 's optimum performance in regard to ad­
hesion, running noise, friction and hydroplaning .
To benefit fully from the advantages of the uni­
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
Finishing
.,. Reinstall the caps on the wheel bolts if neces­
sary .
.,. Store the vehicle tool kit in its designated
place .
.,. If the removed wheel does not fit in the spare
wheel well, store it securely in the luggage
compartment
¢ page 183.
.,. Check the tire pressure on the installed wheel
as soon as possible.
.,. Check the tire pressure and store it in the Info­
tainment system.
.,. The wheel bol t tightening specification must be
90 ft lbs (120 Nm) . Check it as soon as possible
with a torque wrench. Drive carefully until then.
.,. Have the faulty wheel replaced as quickly as
possible.
278
(D Tips
- If you notice that the wheel bolts are cor­
roded and difficult to turn while changing a
tire, they should be replaced before you check the tightening torque.
- Drive at reduced speed until you have the
tightening torques checked.
Notes on wheel changing
Please read the information ¢ page 251 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 immedi­
ately 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.
- 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
were factory installed, then be sure to read
the information
¢page 251.
-Always make sure the damaged wheel or
even a flat tire and the jack and tool kit are
properly secured in the luggage compart­
ment and are not loose in the passenger
compartment.
- In an accident or sudden maneuver they
could fly forward, injuring anyone in the ve­
hicle.
