-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much . This increases the
risk of an accident because it
can cause the tire to burst and result in loss of vehicle con­
trol.
-Incorrect tire pressure in­
creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident .
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­ ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side B­
pillar, always follow the specifica­
tion on the B -pillar label

'® For the sake of the environment
-Tire pressure that is too low
increases fuel consumption.
-Fuel consumption may also in­
crease when driving with the
comfort tire pressure is se­
lected.
Audi recommends using the
tire pressure specified for a
normal load
¢ table on
page 346
or for a full load
when the vehicle is partially
loaded.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.
The following table lists recom­ mended tire pressures in cold
tires according to the load and

Please note the important safe­
ty precautions regarding tire
pressure
¢ page 344 and load
limits
¢ page 347 .
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­ sengers also depends on making
sure that load limits are not ex ­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories , a full tank of
fuel, oil, coolant and other fluids
Wheels
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­ ed as part of the vehicle load .
The
Gross Axle Weight Rating
( " GAWR ") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle 's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.

the risk of a n acc ident beca use it can cause
the tire to burst.
- Always adapt your driving to the road and
traff ic conditions. Drive carefully and red uce
yo ur speed on icy or slippery roads. Even
winter tires can lose traction on b lack ice.
@ For the sake of the environment
Reinstall summe r tires at the approp riate
time, because they provide better hand ling
when roads are free of snow and ice. S ummer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
w inter t ires. Please note that in some coun­
tries w here w inte r ti res are req uired, only
w inter t ires with the
& symbol may be per ­
m itted.
Snow chains
Snow ch ains not only i mprove the d riving in win ­
t er ro ad cond itions, b ut also the brak ing.
... Only insta ll snow chains o n the front wheels .
T h is applies also to ve hicles w ith all wheel
drive* .
... Check an d cor rect the sea ting of the snow
c h ains a fte r dr iv ing a few feet, i f necessary. Fo l­
l ow the instructions from the manufacturer .
... Note the maximum permitted speed when d riv ­
ing with snow chains . Do not exceed 30 mp h
(SO km/h).
Use of snow chains is on ly pe rmitted with certain
rim/t ire combinations due to technical reasons.
Check with an authorized Audi dealer o r autho r­
ized Aud i Service Fac ility to see if yo u may use
snow chains.
Use
fine -mesh snow chains . They must not add
more t han 0.53 in (13.5 mm) in height, includ ing
the chain lock .
You must remove the snow c hains on roads wit h­
out snow. Othe rw ise, you could impa ir dr iv ing
ab ility and damage the tires.

A WARNING ~
Using incorrect snow chains or installing snow
cha ins i ncor rectly can result in loss of veh icle
con trol, which increases the risk of a n acci­
d ent.
(D Note
Snow chains can damage the rims/whee l cov­
e rs* if the chains come into direct contact
wi th them . Remove the whee l covers* first.

Low-profile tires
Applies to: vehicles with low-profile tires
Your vehicle is equip ped wi th low -profi le t ires* at
t h e factory. Compa re d t o o ther tire/r im com bina ­
tions, low -profi le tires offer a w ider tread surface
and a larger rim diameter with shorter tire side­
walls . This results in an agile dr iv ing style. How­
ever, it may reduce the leve l of com fort and in­
crease road noise whe n driving on roads in poor
cond it ion.
Low-p rofile ti res can become damaged mo re
q uick ly than standard tires when dr iv ing ove r
l a rge bumps, potholes, manhole covers, speed
bumps and curbs . Therefore, it is particularly im­
po rtan t to maintain the correct tire pressure
<:;> page 344.
To reduce the risk of damage to the tires and
rims, drive very caref ully on poor roads.
Check your wheels regu larly eve ry 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims .
After a heavy impact o r damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dea ler or authorized Audi
Service Facility .

Wheels
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire
inflation pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure tell­
tale when one or more of your 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
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability.
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 .
352
· If the tire pressure monitoring 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.
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires. If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
[I] and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
c:> page 353. The tire pressure moni­
toring system only monitors the tire pressure you
have stored . Refer to the tire pressure label for
the recommended tire pressure for your vehicle
c:> page 344, fig . 2 77.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low
- the tires have structural damage
- the tire was replaced or the tire pressure was
changed and it was not stored

- tires that are only partially used are replaced
with new tires
