Side assist functions at speeds above approx i
mately 19 mph (30 km/h).
@ Vehicl es th at ar e approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still
somewhat far away. The fas ter a vehicle ap
p roaches, the sooner the display in the exteri
or m irror will t urn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr itical
for a lane change. All vehicles detec ted by
side assist are indicated by the time they en
ter your "blind spot", at the latest.
Audi side assist 103
@ Veh icle s left behind
If you s low ly pass a vehi cle that s ide assist has
detected (the difference in speed between the
vehicle and you r vehicle is less than 9 mph
(15 km/h)), the display in the exterior mirror
turns on as soon as the vehicle enters your blind spot.
T he disp lay will not t urn on if you quickly pass
a vehicle that side assist has detected (the dif
ference in speed between the veh icle and your
vehicle is greater than 9 mph (15 km/h)).
Functional limitations
The radar senso rs are designed to detect the
left and right adjacent lanes when the road
lanes are the normal width. In certain situa
tions, the disp lay in the exterior mirror may
turn on even though there is no vehicle locat
ed in the area that is cr itical for a la ne change.
For example:
- if the lanes are narrow or if your are dr iving
on the edge of your lane.
If this is the case,
the system may have detected the vehicle in
another lane that is
not adjacent to your
current lane .
- if you a re driving through a curve. Side assist
may react to a vehicle that is one lane ove r
from the adjacent lane.
- if side assist reacts to other objects (such as
high or d isp laced guard rails) .
- In poor weather conditions. The side assist
functions are l imited .
Do not cover the radar sensors <=>
fig. 117 with
stickers, depos its, bicycle wheels or other ob
jects, because this will affect the funct ion. Do
not use s ide ass ist when towing a trailer. For
i nformation on cleaning, refer to<=>
page 195.
_&. WARNING
- Always pay attention to traffic and to t he
area a round your ve hicl e. S ide assist can
not repla ce a driver's attention. T he driv
er a lone is always responsible for lane
changes and similar driving mane uvers.
-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al
ways stop as soon as it is safe to do so
and check the wheels and tires for dam
age .

of the same size, construction and tread type.
For details see~
page 184 .
.8_ WARNING
Sudden tire failure can lead to loss of con
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning" and toss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds .
- Never mount used tires on your vehicle if
you are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.

contribution to good road ho lding and safe
handling when in good condition and properly
inflated
¢ ,& .
We recommend that all work on tires and
wheels be perfo rmed by an authorized Audi
dea ler. They are familiar with recommended
proced ures and have the necessary spec ial
too ls and spare parts as well as the proper fa
cilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about techn ica l requ irements for
installing or changing tires and r ims.
Re placing t ires and whe els
Tires sho uld be rep laced at least in pairs and
not individua lly (for examp le both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitoring system*
¢page 240.
A lways buy rep lacement radial tires that have
the same specifications as the tires approved
for your vehicle by Audi. Replacement t ires
must always have the same load rating speci
fication as the original equipment or approved
optional tires listed in the table
c:> page 226.
Aud i-approved specification ti res are specially
matched to your vehicle and its load limits,
and can contribute to the important road ho ld
ing, driving characteristics, and safety of the
vehicle. The table (c:>page 226) lists spec ifica
tions of the tires approved for the Audi mod
els covered by your Owner's Literature .
The tire pressure labe l located on driver's side
B-pillar (c:>page 226, fig. 183) lists the speci
f ications of the orig inal equipment tires in
stalled on your veh icle at the time it was man
ufactured.
Federal law requires t ire manufacturers to
p lace standard ized information on the s ide
wall of all tires c:>fig. 186. This information
i dent ifies and describes the fundamental
characterist ics, the quality grade of the tire
and a lso provides a tire ident ificat ion number f
or sa fety standard ce rtification and in case of
a reca ll.
Tire specifications
Knowledge of ti re specificat ions makes it eas
ier to choose the correct tires. Radial ti res
have the tire specifications marked on the
sidewa ll, for examp le:
P255 / 35 R1 9 96Y XL
This co nta ins the following information:
P Indicates the t ire is for passenger cars
(where app licab le)
2 55 Nominal tire width in mm of the tire
from sidewall edge to sidewa ll edge. In
general, the larger the number, the wider
the tire
35 Height/w idth ratio in percent (aspect ra-
t io)
R Tire construction: Radial
1 9 Rim diameter code (in inches)
9 6 Load rating code
Y Speed rat ing letter code
X L (or "xl", "EXTRA LOAD", or "RF" Indicates
t h at the t ire is a"Re inforced" or an " Extra
Load " tir e
M+S (or "M/S") Indicates that the tire has
some mud and snow capabi lity
The tires could also have the information of
direction of rotat io n
c:> page 222 .
Tire manufacturing date
The manufact uring date is also indicated on
the tire sidewall (possibly on ly on the inner
s ide of the wheel) :
"DOT ... 2213 ... "means, for example, that
the tire was produced in the 22nd week of 2013.
Speed rating (letter c ode)
The speed rating letter code on the whee ls in
dicates the maximum permissible road speeds
c:> & in Winter tires on page 238 .
P up to 93 mph (150 km/h)
Q u p to 99 mp h (158 km/h)
R up to 106 mph ( 170 km/h)
236 Tire s and whee ls
- All four wheels must be fitted with radia l
t ires of th e same ty pe, size (r olling c ir
cumfe rence) and the same tread pattern.
Dr iv in g with different tires reduces veh i
cle handling and can lead to a loss of
c o ntrol.
- If the spare tire is not the same as the
t ires that are mounted on the veh icle -
for example with winter tires - on ly use
the spare tire for a short period of time
and dr ive with extra care. Refit the no r
ma l road whee l as soon as safely possi
ble.
- Never drive faster than the maxim um
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
sudden ly.
- Overloading ti res cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades app ly to tires that
are properly inflated and not over or un
derinflated.
- For technical reasons it is not a lways
poss ible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel tr im discs on the ve
hicle whee ls, make sure that the air flow
to the brakes is not blocked . Reduced air
flow to the brakes can them to overheat,
increasing stopping d istances and caus
ing a collision.
- Run flat t ires may on ly be used on
vehicles that we re eq uipped w ith them
at the factory. The vehicle must have a
chassis des igned for r un flat t ires and a
factory-installed tire press ure monito r
ing system * that indicates a loss of tire
pressure. Incorrect use of run flat tires
can lead to vehicle damage or accidents.
Check with an authorized Audi dea ler or
t ire spec ialist to see if you r vehicle can be
equipped with run flat tires .
If run flat
t ires a re used, they must be insta lled on
all four wheels. M ixing tire types is not
permitted.
(D Note
- For technical reasons, it is not generally
poss ible to use the wheel rims from oth
er veh icles. T his can hold tr ue for wheels
of the same vehicle type.
- If the spare tire is different from the tires that you have mounted on your ve
hicle (for example winter tires or wide
profi le tires), then use the spare tire for a
short period of time only and drive w ith
extra care. Replace the flat tire w it h the
ti re mat ching the othe rs on your vehicle
as soon as possi ble.
- Never d rive without the valve stem cap.
The v alves co uld get damaged.
@ For the sake of the environment
Dispose of o ld tires in accordance w ith the
l ocal requirements.
Uniform tire quality grading
- Tread wear
- Tra ction AA A B (
- Temperature ABC
Quality grades can be found where applicable
on the t ire s ide wall between tread shoulder
and maximum section width
c> page 233,
fig . 186.
For e xample: Tread wear 200 , Traction AA ,
Temperature A .
All passenger car ti res must conform to Feder
al Safety Requirements in add ition to these
grades .
Tread w ear
The tread wear g rade is a comparative rating
based on the wear rate of the tire when tested
u nder contro lled conditions on a specified
government test course.
F o r example, a tire graded 1S0 wo uld wear
one and one ha lf (11/2) times as well on the
government course as a ti re graded 100. ..,_
driving a few yards and correct if neces
sary . Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer
tain roads, this norma lly also applies to
veh icles with all wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory insta lled r ims . If different rims are fit
ted, the correct wheel bo lts wit h the right
l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
is the same model<=>
page 266.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
cont ro l, a co llision and serious persona l in
Jury .
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
w hee l bolts can t urn easily and be p rop
erly t igh tened.
- Never grease or oil the wheel bolts and
the threads in the wheel h ubs. They can
become loose wh ile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- Only use whee l bo lts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Alw ays m ain ta in the co rrec t tig hten ing
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor
que of the wheel bo lts is too low, they
can loosen and come out when the vehi-
Tire s an d wheel s 239
cle is mov ing. If the tightening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) w ith a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque whee l bolts
diagonally . After changi ng a wheel, the
torque m ust be checked as soon as poss i
ble with a to rque wrench -preferably by an
a uthorized Aud i dea le r or qualified wor k
shop .
Low aspect ratio tires
Your A udi is fac tory -eq uipped w ith low aspect
ratio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi
tions . Ask your authorized Aud i dealer for
more details .
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation. The numera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width exp ressed in percentage. Conven
tiona l tires have a he ight/w idth ratio of 60 or
more.
The performance of low-a spect-r atio tire s is
particularly sensit ive to improper inflation
pre ssure. It is therefor e important that low
a spect ratio tire s are inflated to the specified
pres sure and that th e inflation pr essure i s
regularly checked and maintained. Tire pre s
sure s should be chec ked at lea st once a
month and always before a long trip
<=> page 228 , Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gull ies
or ridges on the road, particularly if the tire is
under inflated . ..,.
