use a spare tire that has the same
circumference as the regular
tires.
&,_ WARNING
-Do not use steel rims that are 17 inches or larger. Other­
wise, damage to the vehicle
and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than six years old when abso-
Wheels
lutely necessary and drive
carefully when doing so.
-Run-flat tires* may only be used on vehicles that were
equipped with them at the
factory
¢ page 3 52.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.

This can increase the risk of an accident because it has a nega­
tive effect on handling, driving
through curves, and braking, and because it increases the risk of hydroplaning when driv­
ing through deep puddles.

A WARNING
Always adapt the tire pressure
to your driving style and vehicle
load.
-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read and follow the important safe­
ty precautions in¢
page 346,
Tires and vehicle load limits .

Wheels
-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.

(i} 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

lected .
(D Tips
Audi recommends using the
tire pressure specified for a
normal load

page 345
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.

&_ WARNING
Please note the important safe ­
ty precautions regarding tire
pressure¢
page 343 and load
limits¢
page 346.
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 deflat ion 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 a re
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 tan k of
fuel, oil, coolant and other fluids
3 4 6
plus maximum load. The maxi­
mum load includes the number of
passengers that the veh icle is in­
tended to carry ("seating capaci­
ty") with an assumed weight o f
150 lbs (68 kg) for each passen­
ger at a designated seat ing pos i­
tion and the total weight of any luggage in the veh icle. If you tow
a trailer, the weight of the trailer
hitch and the tongue we ight 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 (inc luding
the weight of a trailer h itch 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 .

are listed on the safety compli­
ance sticker label located on the
driver's side 8-pillar.
.&_ WARNING
Overloading a vehicle can cause loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than
your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to­
tal load being transported - incl uding the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle heavier than the vehicle's
Gross Vehicle Weight Rating.
Wheels
Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload­
ed.
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS" on your vehicle's placard
(tire inflation pressure label)
¢ page 343, fig. 2 76.
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the stick­
er ¢
page 343, fig. 2 76.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex­
ample, if the
"XXX" amount
equals 1400 lbs. and there will.,,.

:E: ' th e risk of an accident because it can cause
the tire t o burst.
- Always adapt yo ur drivi ng to the road and
traff ic conditions. Drive carefully and red uce
your speed on icy or slippery roads. Even
winter tires can lose traction on black ice.
@ For the sake of the environment
Reinstall summer ti res at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, t ire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
w inter tires . Please note that in some coun­
tries where w inter t ires are required, only
w inter t ires with the
die. symbol may be per­
m itted.
Snow chains
Snow chains no t only imp rove the driving in wi n·
t er roa d cond itions, but a lso the brak ing.
" Only insta ll snow chains o n the
front wheels .
" Check and cor rect the sea ting of the snow
chains after dr iv ing a few feet, if necess ary. Fo l­
low the ins truc tions from the ma nufa cturer .
" Note the maximum pe rmit ted speed w hen driv ­
ing with snow chains . Do not exce ed 30 mph
(SO km/h).
Use of snow chains is only pe rm itted with certain
rim/ti re combinations due to tec hnical reasons .
Chec k with an authorized A udi d ealer or author­
ized A udi Service F acili ty to see if yo u may use
snow chains.
Use
fine-mesh snow chain s. They must not add
mo re t han 0.53 in (13 .5 mm) in height , including
the chain lock .
You mus t remove the snow c hains on roads with ­
out snow . Otherw ise, you could impair dr iving
abi lity and damage the tir es .

A WARNING
Using incorrect snow chains or install ing snow
cha ins incorrectly can resu lt in loss of veh icle
control, which increases the risk of a n acci­
dent.
(D Note
- Snow chains can damage the rims/wheel
cove rs* if the chains come into direct con ­
t act with them . Remove the wheel covers*
first . Use coa ted snow cha ins .
- Do not install and use snow c hains if the re is

Low-profile tires
Applies to: vehicles with low-profile tires
Your vehicle is equipped with low -profi le tires* at
the factory . Compared to other tire/rim combina­
tions, low-prof ile 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 level of comfort and in ­
c rease road noise when driving on roads in poo r
cond it ion.
Low-profile t ires can become damaged more
quickly than standard tires when dr iving over
la rge bumps, potholes , manhole covers, speed
bumps and curbs. Therefo re, it is particularly im­
po rtant to mainta in the co rrect ti re pressure
q poge 343.
To reduce the risk of damage to the tires and
r ims, drive very caref ully on poor roads.
Check your wheels regu larly every 2,000 mi
(3,000 km) for damage . For example, chec k for
bulges/cracks on the tires or deformations/
c racks on the rims . .,..

:E: ' Tire pressure monitoring system
UJ General notes
Each tire, including t he spare (if provided),
should be checked monthly when cold and inflat­
e d to the inflation pressure recommended by the
veh icle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a different size than the size indicated on
the veh icle placard or t ire inflation pressure la­
be l, you shou ld determine the prope r ti re infla­
tion pressure fo r those t ires) .
As an added safety feature , your veh icle has been
equ ipped w ith a t ire pressure monitoring system
(TPMS) that illuminates a low tire p ress ure te ll­
tale whe n one or more of yo ur t ires is significant­
l y under- infla ted . Accordingly, when the low tire
p ressure tellta le ill uminates, yo u should stop and
check your tires as soon as possible, and inflate
them to the proper press ure. Driving on a s ignifi ­
cantly under-inflated tire causes the tire to over­
heat and can lead to t ire failure. Under-inflation
also reduces fuel efficiency and tire 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 ility to ma inta in correct tire p ressure,
even if u nder-inflation has not reached t he leve l
to tr igger illum inat io n of the TPMS 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 indicator is combined w ith the low tire
p ressure tellta le. Whe n the system de tects a
mal function, the te lltale will flash fo r approxi ­
mate ly one min ute and then remain continuo usly
illum inated. This sequence will continue upon
subseq uent veh icle start-ups as long as the ma l­
function ex ists .
When the malfunction indicator is ill uminated,
the system may not be ab le to detect or signa l
low tire press ure as intended. TPMS ma lfunctions
may occur for a var iety of reasons, including the
Wh eel s
insta llation o f replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning p roper ly . Always check the
TPMS ma lfunction te lltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the rep lacement or a lternate tires a nd
wheels allow the TPMS to continue to fu nction
prope rly .
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 mo/function .
Using the ABS se nsors, the t ire pressu re moni to r­
i ng system compares the tire tread circumfer ­
en ce and vibr ation character ist ics of the ind ividu­
al tires . If the press ure changes in one o r more
t ires , th is is indicated in the instrument cluster
display with an indicato r light
[I] and a message.
If only one tire is affected, the location of that
t ire will be indicated.
T he tire press ures must be stored in the Infotain ­
ment system again each time the p ressures
change (switching between partial and full load
pressure) or after changing or replac ing a tire on
your vehicle
