2014 AUDI RS7 SPORTBACK width

94 Audi side assist
Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
(D Vehicles that are approaching
I n certain cases, a vehicle will be classified as
cr itica l for a lane change even if it is still
somewhat far away . The faster a vehicle ap­
proaches, the sooner the display in the exteri ­
or mirror will turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior m irror if they are classified as critica l
for a lane change. All vehicles detected by
side assist are indicated by the time they en­
ter your "blind spot", at the latest.
@ Vehicles left behind
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the
vehicle and your vehicle is less than 9 mph or
15 km/h), the disp lay in the exterior mirror
turns on as soon as the vehicle enters your blind spot.
The display will not turn on if you quickly pass
a vehicle that side assist has detected (the dif­
ference in speed between the vehicle and your
vehicle is greater than 9 mph or 15 km/h).
Functional limitations
The radar sensors are designed to detect the
left and right adjacent lanes when the road
lanes are the normal width. In certain situa­
tions, the display in the exterior mirror may
turn on even though there is no vehicle locat­
ed in the area that is critical for a lane change.
For example:
- if the lanes are narrow or if your are driving
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 are driving through a curve. Side assist
may react to a veh icle that is one lane over
from the adjacent lane.
- if side assist reacts to other objects (such as
high or displaced guard ra ils). -
In poor weather conditions . The side assist
functions are limited.
Do not cover the rada r senso rs
~ fig. 104 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the funct ion . For
information on cleaning, refer to
~ page 203.
A WARNING
-
- Always pay attention to traffic and to the
area around your vehicle. Side assist can­
not replace a driver's attention. The driv­
er alone is always responsible for lane
changes and similar dr iving maneuvers .
- Improper reliance on the side assist sys­
tem can cause coll is ions and serious per­
sonal injury:
- Never rely on ly on side assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der all conditions -danger of accident!
- Please note that side assist indicates
there are approaching vehicles, or
vehicles in your blind spot, only after
your vehicle has reached a driving speed
of at least 19 mph (30 km/h).
- In certain sit uations, the system may not
function or its function may be limited.
For example:
- if vehicles are approaching or being left
behind very quickly. The disp lay may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow o r heavy mist.
- on very wide lanes, in tight curves or if
there is a rise in the road surface.
Vehicles in the adjacent lane may not
be detected because they are outside
of the sensor range .
([) Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
u nderbody. This can affect the system. .,..

dealer. They are familiar with recommended procedures and have the necessary special
tools and spare parts as well as the proper fa­
cilities for disposing of the old t ires.
Authorized Audi dea lers have the necessary
information about technical requirements for
i nstalling or changing tires and rims .
Replacing tires and wheels
Tires should be replaced at least in pa irs and
not individually (for examp le both front tires
or both rear tires together) .

Tire specifications
Knowledge of tire specifications makes it eas­
ier to choose the correct tires. Radial tires
have the tire spec ifications marked on the
sidewall, for example:
275/35 R 20 102 Y XL
This contains the follow ing informat ion :
P Indicates the tire is for passenger cars
(where applicable)
275 Nominal tire width in mm of the tire
from sidewall edge to sidewall edge. In
general, the larger the number, the w ider
the tire
35 Height/width ratio in percent (aspect ra-
tio)
R Tire construction: Radia l
20 Rim diameter code (in inches)
102 Load rating code
Y Speed rat ing letter code
XL (or "xl", "EXTRA LOAD" or "RF") Indicates
that the tire is a "Reinforced " or an " Extra
L oad" tire
M+S (or "M/S") Indicates that the tire has
some mud and snow capability
The tires could also have the information of
d irection of rotation¢ page 228.
Tire manufacturing date
The manufacturing date is also indicated on
the tire s idewall (possibly only on the inner
side of the wheel):
"DO T ... 2213 ... " means, for examp le, the tire
was produced in the 22nd week of 2013.
Speed rating (letter code)
The speed rating letter code on the wheels in ­
dicates the maximum permissib le road speeds

U.S. DOT Tire Identification Number (TIN)
and tire manufacture date
This is the tire's "serial number". It begins
with the letters "DOT" and ind icates that the
t ir e meets all federal standards . The next two
numbers or l etters ind icate the plant where it
was manufactu red, and the last four numbers
represent the week and year of man ufacture.
For example, the numbers 2213 mean the tire
was produced in the 22nd week of 2013. The
other numbers are marketing codes that may
or may not be used by the tire manufacturer.
This information is used to contact consumers
if a tire defect requires a recall.
Audi Original tire
Tires w ith the identification "AO" or "RO" have
been specially matched with your Audi. We
recommend using only these tires because
they meet the highest standards regarding
safety and driving characterist ics when used
correctly. Your authorized Audi dealer will
gladly provide you with more inf ormation.
Tire ply composition and materials used
The number of plies indicates the number of
layers of rubber-coated fabric in the tire. In
genera l, the greater the number of pl ies, the
more weight a tire can support. T ire

24 2 T ire s and wheel s
-If a replacement tire is different from
the tires that you have mounted on your
vehicle (for example winter tires or wide profile tires), then use the replacement
tire for a short period of time only and
drive w ith extra care. Replace the flat tire
with the tire matching the others on your
vehicle as soon as poss ible.
- Never dr ive without the valve stem cap .
The valves could get damaged.
@ For the sake of the environment
Dispose of old t ires in accordance with the
local requ irements.
Uniform tire quality grading
- Tread wear
- Traction AA A BC
- Temperature ABC
Quality grades can be found where applicable
on the tire side wa ll between tread shou lder
and max imum section width
¢ page 239,
fig. 199.
For example: Tread wear 200 , Traction AA,
Temperature A.
All passenge r car tires must confo rm to Feder ­
a l Safety Requirements in addition to these
grades .
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
u nder cont rolled conditions on a spec ified
government test course .
For example, a t ire graded 1S0 wou ld wear
one and one half (11/ 2) t imes as well on the
gove rnment course as a tire graded 100.
The relat ive perfo rmance of t ires depends
upon the a ctua l conditions of their use, how ­
ever, and may depart sign ifican tly from the
n orm due to var iat ions in dr iving habits, serv­
ice practices and differences in road cha racte r­
istics and climate .
Traction
The traction grades, from highest to lowest,
are AA, A, Band
C. Those grades represent the
ti re's ability to stop on wet pavement as
measured under contro lled conditions on
specified government test surfaces of aspha lt
and concrete. A t ire marked C may have poor
traction performance ¢.&,. .
Temperature
The temperature grades are A (the highest),
B, and C, representing the tire's resistance to
the generation of heat and its ab ility to dissi­
pate heat when tested under controlled condi­
t ions on a specif ied indoo r laboratory test
wheel.
Sustained h igh temperature can cause the
mater ial of the tire to degenerate and reduce
t ire life, and excessive temperature ca n lead
to sudden tire failure
~ .&,. .
The grade C corresponds to a level of perform ­
ance which all passenger car tires must meet
under the Federal Motor Vehicle Safety Stand­
ard No. 109 . Grades Band A represent h igher
levels of performance on the laborato ry test
whee l than the minimum requ ired by law.
_& WARNING
The t raction grade assigned to t his tire is
based on s traight-ahead braking trac tion
tests, and does not include accelerat ion,
cornering, hydroplaning or peak t raction
cha racte rist i cs.
A WARNING "--
The temperature grade for this tire is es-
tablished for a tire that is properly inflated
and not overloaded. Excess ive speed, un­
derinflation, or excess ive load ing, either
separately or in combinat ion, can cause
heat bui ldup and possib le tire failure.

risk of a wheel loss . If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving. If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
c ome loose.
(D Note
The spec ified torque for the wheel bo lts is
90 ft lb (120 Nm) w ith a tolerance of ± 7,4
ft lb(± 10 Nm) . Torque wheel bo lts d iago­
na lly . After chang ing a wheel, the torque

Low aspect ratio tires
Your Audi is factory-equipp ed with low aspect
ratio t ires. These t ires have been thorough ly
tested and been selected spec ifically for your
model for the ir superb performance, road feel
and handling unde r a va riety of driving condi­
tions. Ask your a uthorized Aud i dea le r fo r
mo re deta ils.
T he low aspect ratio of these tires is indicated
by a nume ral of
55 or less in the tire's size
des ignation . T he numeral represents the rat io
of the ti re's sidewall height in relat io n t o its
tread wid th expressed in per cen tage . C o nven­
tional t ires have a height/width ra tio of 60 or
mo re.
Th e performan ce of low -aspe ct-ratio tir es is
parti cularl y se nsitive to improper inflation
pressure . It is therefore impor tant that low
a s pect ratio tire s are inflated to the specified
pressure and that the inflation pre ssure is
regularly checked and maintained. Ti re pres­
sures should be checked at least once a
month and always before a long trip
c::> page 234, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
eas ily by impact with potho les, curbs, gu llies
Tire s an d wheel s 245
or r idges on the road, partic ularly if the tire is
u nderinflated.
In orde r to minimize t he occ urren ce of impact
dam age to the tires o f your vehi cle, we recom ­
mend that you observe the following p reca u­
tions:
- Always ma int ain re commended inflation
pressu res . Check your tire pressu re eve ry
2,000 miles ( 3,000 km) and add air if neces ­
sary.
- Dr ive ca re fu lly on roads with potholes, deep
gullies o r ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires .
- After any impact, immed iate ly inspect your
tires or have them inspected by the nearest
au thor ized Audi dealer. Replace a damaged
tire as soon as possible .
- Inspect your tires every 2,000 m iles (3,000
km) for damage and wear. Damage is no t al­
ways easy to see . Damage can lead to loss of
air a nd under inflat ion, which could eventu­
ally cause tire failure .
If you believe that a
t ire may have been damaged, rep lace the
t ire as soon as possib le.
- These tires may wear more quickly tha n oth­
ers.
- Please also remember that, while these tires
de live r respon sive handling, they may ride
less comfo rtably and m ake more noise tha n
other choi ces .
Reduced performance in winter /cold
season conditions
A ll ti res are designed for cer ta in p urposes.
T he low aspect ratio, ult ra h igh performance
tires originally installed on your vehicle are i n­
tended for maxim um dry and wet road per­
f ormance and handling. They are not suitable
for cold , snowy or icy weather condi tions. If
you drive under those circumstances, you
shou ld equ ip your vehicle w it h all -season or
winter tires, which offer bette r traction under
those conditions. We suggest you use the rec­
ommended snow o r all-season t ires specified
f o r yo ur vehicle , or t hei r equivalent . .,..
