Only use refill bottles that are approved for
your veh icle. Us ing other systems can cause
Ad Blue to leak.
-You can obta in refill bottles from an author­
i zed Audi dealer or author ized Audi Service
Fac ility.
- A perm itted refill bottle contains approxi­
mately 0.5 gallon ( 1.9 liters) of Ad B lue.

After filling
The vehicle must be driven so that the system
recognizes t hat the Ad Bl ue was refilled. This can
take severa l min utes .
• If there was no Ad Blue left in the tank and a
range of O mi (0 km) was shown in the display ,
switch the ign ition on for about 3 0 seconds be­
f ore star ting the engine .
(D Tips
Ad Blue in the tank can free ze at very low tem­
pe ra tures. If this happens, the system will
no t detect t hat the Ad Bl ue was refilled and i t
wi ll continue to inform you of the low Ad Blue

level. The message t urns off as soon as the
tank thaws out again .
Emissions control
systems
Catalytic con verter
Applies to: vehicles with gasoline engines
T he vehicle may only be driven with un leaded
gasoline, otherwise the catalytic converter will be
destroyed.
Never drive until the tank is compl ete ly empty .
The irregu lar supply of fuel that resu lts from that
can cause eng ine misfires. Uncombusted fuel will
enter the exhaust system, which can cause over­
heating and damage to the catalytic converter .
Diesel particulate filt er
Applies to: vehicles with diesel engines
The diese l particu late filter filters near ly all of
the soot particles out of the exhaust. The filter
cleans itself automatically under norma l driving
condit ions. If the filter cannot clean itself (for ex­
ample, because you are only driving short distan ­
ces), the filter becomes clogged with soot and

_& WARNING
The tempera ture of the exhaus t sys tem is
high, bot h when driv ing and a fter stoppi ng
the engine.
- Never tou ch the e xhaust tail pipes once they
have become hot. This cou ld res ult in burns .
- Do not par k your veh icle over flamm ab le
materia ls such as grass or leaves because
the high temperature of the emissions con­ trol system (catalytic converter or diesel particu late filter) cou ld start a fire.
-Do not app ly underbody protectant in the
exhaust system area, beca use this increases
the risk of f ire.

Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.

Wheel s
Bead separation
means a breakdown of the bond
between components in the bead .
Cord
means the strands forming the
plies in the t ire.
Cold tire inflation pressure
means the tire pressure recom­
mended by the vehicle manufac­
turer for a tire of a designated
size that has not been driven for more than a couple of miles (kilo­
meters) at low speeds in the
three hour period before the tire
pressure is measured or adjusted.
Curb weight
means the weight of a motor ve­
hicle with standard equipment in­
cluding the maximum capacity of
fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
E x tra load tire
means a tire designed to operate
at higher loads and at higher in­
flation pressures than the corre­ sponding standard tire . Extra load
tires may be identified as
"XL",
"xl", "EXTRA LOAD", or "RF" on
the sidewal l.
344
Gross Axle Weight Rating
("GAWR ")
means the load-carrying capacity
of a single axle system, measured
at the tire -ground interfaces .
Gross Vehicle Weight Rating
(" GVWR ")
means the maximum total loaded
weight of the vehicle .
Groove
means the space between two ad­
jacent tread ribs .
Load rating (code )
means the maximum load that a
tire is rated to carry for a given in ­
flation pressure. You may not find
this information on all tires be­
cause it is not required by law.
Ma ximum load rating
means the load rating for a tire at
the maximum permissible infla­ tion pressure for that tire.
Ma ximum loaded vehicle
weight
means the sum of :
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity weight, and
(d) Production options we ight

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.
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 8-
pillar, always follow the specifica­
tion on the 8-pillar label
¢ page 351, fig. 284.
352
(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
comfort tire pressure is se­
lected .
(D Tips
Audi recommends using the
tire pressure specified for a
normal load
¢ table on
page 353
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
the size of the tires installed.

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
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-
Wheels
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 Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compli­ ance sticker on the front end of
the driver's door.

Wheels
@ For the sake of the environment
Reinstall su mmer tires at the appropriate
time, because they pro vide better handling
when roads are free of snow and ice. Summer tires cause less road noise, tire wear and fuel
consumption.
@ Tips
You can also use all season tires instead of
w inter t ires. Please note that in some coun­
tries where w inter tires are required, only
w inter t ires with the
& symbol may be per­
m itted.
Snow chains
Snow chains not only imp rove the dr iving in w in ­
ter ro ad conditions, b ut also the brak ing .
.,. Only install snow chains o n the front wheels .
.,. Check and cor rect the seating of the snow
c h ains after dr iv ing a few feet, if ne cessa ry . Fo l­
low the ins tructions from the m anufactu rer.
.,. Note the maximum permit ted speed when driv ­
ing with snow chains. Do not exceed 30 mp h
(SO km/h) .
Use of snow chains is o nly pe rmitted with certain
rim/tire combinations due to technical reasons .
Check with an authorized A udi dealer or author­
ized Audi Service Fac ility to see if you may use
snow chains.
Use fine-mesh snow chain s. They must not add
more t han 0.53 in (13 .5 mm) in height, includ ing
the chain lock .
You mus t remove the snow chains on roads w it h­
out snow . Otherwise, you could impai r dr iving
abi lity and damage the tires .
A WARNING
Us ing inco rrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
control, which increases t he risk of an acc i­
dent .
358
(D Note
Snow chains can damage the rims/whee l cov ­
ers * if the c ha ins come into direct contact
with them . Remove the whee l cove rs* first.
Use coated snow chains.
(D Tips
When using snow chains, it may be usefu l to
switch on sport mode

Low-profile tires
App lies to: vehicles with low-profi le tires
Your vehicle is equipped with low-profile t ires* at
the factory. Compared to other tire/r im combina­
t ions, low-profi le tires offer a w ider t read surface
and a la rger r im diamete r with shorter tire side­
walls. This results in an agile dr iv ing style. How­
ever, i t may reduce the leve l of com fort and in ­
crease road noise whe n driving on roads in poo r
condition .
Low-p rofile ti res ca n become damaged mo re
q uickl y than st andar d tires when dr iv ing ove r
l a rge bumps, potholes, manhole covers, speed
b u mps and curbs . Therefore, it is particularly im ­
portant to maintain the correct tire pressure
r::> page 3 51.
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 m i
( 3 ,00 0 km) for d amage. For ex am ple, c heck for
bulges/crac ks on the tires or deformations/
c racks on the rims.
Af ter a heavy imp act o r damage, have the tires
and rims i nspected or replaced immedia tely by
an a uthorized Audi dea le r or authorized Audi
Service Facility .
Low-p rofile ti res c an wear out f aster than stand­
a rd tires.
Summer tires are not suitable fo r cold weather,
snow or black ice. If yo u are d rivi ng in these con­
d it ions, use wi nter or a ll season tires
r=> page 357.

Wheels
check you r 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 t ire failure. Under-inflation
also reduces fuel efficiency and t ire tread life,
a nd may affect the veh icle's handling and stop ­
p ing ability .
Please note that the TPMS is not a substit ute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma inta in correct tire pressure,
even if under-inflation has not reached the level
to tr igger illum inat io n of the TPMS low tire p res­
sure tellta le.
Your veh icle has also bee n eq uipped w ith a TPMS
malfunct ion i nd icator to indicate when the sys­
t e m is not operat ing properly. The TPMS ma l­
f u nction indicator is comb ined w ith the low tire
p ress ure tellt ale. Whe n the system dete cts a
malfunct ion, the te lltale will flash for approxi­
mate ly one min ute and then remain continuo usly
i l luminated. This sequence will continue upon
subseq uent veh icle start- ups as long as the ma l­
function ex ists .
When the malf unctio n indicator is ill uminated,
the system may not be able to detect or signa l
low tire pressure as intended . TPMS ma lf u nctions
may occur for a variety of reasons, including the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS from functioning prope rly . Always c heck the
TPMS malfunct ion tellta le afte r replacing one o r
mo re t ires o r whee ls on your ve hicle to e nsu re
t hat the repla cement or altern ate t ires and
wheels a llow the TPM S to con tinue to function
p roperly.
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 mon itor­
ing system compares the tire tread circ umfer­
ence and vibration cha racteristics of the individu­
a l tires. If the pressure changes in one or more
tires, this is ind icated i n the instrument cluste r
