2013 AUDI RS5 CABRIOLET width

102 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
(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 (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. 117 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the function . For
information on cleaning, refer to~
page 193.
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
s ur e that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
de r 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 approach ing or being left
behind very quickly. The disp lay may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow or 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. .,..

190 Cleaning and protection
Automatic car wash
Th e ve hicl e can be washed in almost any
modern automatic car wash .
The vehicle paint is so du rable that t he ve hicle
can normally be washed without problems in
an automatic car wash . However, the effect on
the paint depends to a large extent on the de­
sig n of the facility, the filte ring of the wash
wate r, the type of wash and care mater ia l, etc.
If th e p aint ha s a dull appearance afte r go ing
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately.
If necessary, use a different car wash.
Th e power top does no t require special pre ­
cautions be fore passing through a car wash.
However , the car mu st not be treated with
hot wa x after the wash cycle!
The wax could
adversely affect the power top and even dam­
age the fabric ove r a period of time.
The power top does not have to be washed ev­
e ry time you use a car wash . The power top
can be spared if the car wash facility is equ ip­
ped with manually adjustable roof brushes or
rollers.
Before going through a car wash, be sure to
take the usual precaut ions such as clos ing the
windows . Remove antenna if applicable.
I f yo u have installed additional accessories on
the vehicle - such as spoilers, etc. - it is best to
ask the car wash operator i f these should be
removed.
On ly use car washes where the vehi cle re ­
mains stationary and the cleaning equipment
moves around the vehicle wh ile washing and
drying. It is not recommended to use car
washes where the vehicle is moved forward on
a conveyer.
A WARNING
- Always read and heed all WAR NIN GS and
ot he r i nforma tio n
¢ page 189.
(D Note
- Before wash ing the ve hicle in an auto­
matic ca r wash, please make su re to re­
tract the exter ior mir rors to prevent
them from be ing damaged .
- Compare the w idth of yo ur vehicle with
the width of the tunne l at the facility.
- Compa re the track of yo ur vehicle with
the distance between the g uide rails of
the facility -there is a risk of damage to
the whee ls and tires.
Washing the vehicle by hand
A lot of water is needed when washing a vehi­
cle by hand.
.,. Before yo u start washing, ma ke s ure you
have read a nd understood the WARNINGS
¢ .&, .
.,. First soak all dried d irt unt il it is soft, then
r inse it off .
.,. As you clean yo ur vehicle, start w ith t he roof
and wo rk your way down to t he bo ttom, us­
ing a sponge, a s ponge g love or a clean
br ush .
.,. Rinse the s ponge o r th e sponge g love o ften,
flushi ng it clean eac h time .
.,. Use spec ia l car shampoo only for very persis ­
tent dirt .
.,. Rinse the car t ho roughly with water.
.,. Use a chamo is leather to gently wipe the ex-
t er ior d ry .
U se a separate sponge for cleaning the
whee ls, door s ills and othe r regions exposed
to road dirt . In this way, yo u w ill not scratch
t h e pa int w ith coarse pa rticles imb edded in
t h e sponge the next time you wash t he ca r.
A WARNING
- W ash your vehicl e only when the ign ition
is swi tched o ff to re duce the r isk o f a
crash .
- Always re ad and heed a ll WA RNIN GS and

224 Tires and wheels
Groove
means the space between two adjacent tread
ribs .
Load rating (code)
means the maximum load that a tire is rated
to carry for a given inflation pressure. You
may not find this informat ion on all tires be­
cause it is not req uired by law.
Maximum load rating
means the load rating for a t ire at the max i­
mum permissible inflation pressure for that
tire.
Maximum loaded vehicle weight
means the sum of:
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity we ight, and
(d) Production options weight
Maximum (permissible) inflation pressure
means the maximum cold inflation pressure
to which a tire may be inflated. Also called
"maximum inflation pressure ."
Normal occupant weight
means 150 lbs. (68 kilograms) times the
number of occupants seated in the vehicle up
to the total seating capacity of your vehicle .
Occupant distribution
means distribution of occupants in a vehicle.
Outer diameter
means the overa ll diameter of an inflated new
tire.
Overall width
means the linear distance between the exteri­
ors of the sidewalls of an inflated tire, includ ­
ing elevations due to labeling, decorations, or
protective bands o r ribs .
Ply
means a layer of rubber-coated parallel cords.
Production options weight
means the combined weight of those insta lled
regular production options weighing over 5
lb s. (2 .3 kg) in excess of those standard items
which they replace, not previously considered
in curb weight or accessory we ight, including
heavy duty brakes, ride levelers, heavy duty
battery, and special trim.
Radial ply tire
means a pneumat ic tire in which the ply cords
that extend to the beads are laid at substan­
t ia lly 90 degrees to the center line of the
tread .
Recommended inflation pressure
see<=> page 223, Cold tire inflation pressure.
Reinforced tire
means a t ire design to operate at higher loads
and at h igher inflation pressures than the cor­
responding standa rd tire. Reinforced tires
may be identified as "XL" "xl" "EXTRA LOAD"
' ' '
or "RF" on the sidewa ll.
Rim
means a metal support for a tire or a tire and
tube assembly upon which the tire beads are
seated.

Rim width
means nominal distance between rim flanges.
Sidewall
means that portion of a tire between the
t read and bead.

A 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 loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es 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.

234 Tire s and wheel s
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. 186) 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. 189. 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:
P2 65 / 35 R1 9 98Y XL
This co nta ins the following information:
P Indicates the t ire is for passenger cars
(where app licab le)
2 65 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)
98 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 ... 2212 ... "means, for examp le, that
the tire was produced in the 22nd week of 2012.
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
vehicle handling and can lead to a loss of
control.
- If the replacement tire is not the same as
the tires that are mounted on the vehicle
- for example with winter tires - only use
the replacement t ire for a short period of
t ime and dr ive with extra care . Refit the
normal road wheel as soon as safely pos­
sible.
- Never drive faste r than the maximum
speed for which the tires on your veh icle
are rated because ti res that are driven
faster than their rated speed can fail
sudden ly.
- Overloading t ires cause heat build-up,
sudden tire failure, including a blowo ut
and sudden deflation and loss of control.
- T emperature grades app ly to tires that
are properly inflated and not over or un­
derinflated.
- For technical reasons it is not a lways
possible to use wheels from othe r
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­ hicle whee ls, make sure that the air f low
to the brakes is not blocked . Reduced air­
flow to the brakes can them to overheat, increasing stopping distances and caus­
ing a collision .
- Run flat tires may only be used on
vehicles that were equipped w ith them
at the factory . The vehicle must have a
chassis des igned for run flat t ires and a
factory-installed t ire pressure monitor­
ing system* that indicates a loss of ti re
pressure. Incorrec t use of run flat tires
can lead to vehicle damage or accidents .
Check with an authorized Audi dea ler or
tire spec ialist to see if your vehicle can be
equipped with run flat tires . If run flat
tires are used, they must be installed on
all four wheels. M ixing tire types is not
permitted .
(D Note
-For technica l reasons, it is not genera lly
possible to use the wheel r ims from oth- er vehicles.
This can hold true for wheels
of the same vehicle type.
- If a rep lacement tire is different from
the tires that you have mounted on your
vehicle (for example winter tires or wide profile tires), then use the rep lacement
tire for a short period of time only and dr ive with extra care. Replace the flat tire
w ith the tire match ing the others on your
vehicle as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged .

local requirements .
Uniform tire quality grading
-Tread wear
- Traction AA A B C
- Tempe rature ABC
Quality grades can be found where applicab le
on the t ire s ide wall between tread shou ld er
and maximum section width c> page 233,
fig. 189 .
For exampl e: Tread wear 200 , Traction AA,
Temperature A.
All passenger car t ires must conform to Feder­
al Safety Requirements in addition to these
grades.
Tread wear
T he tread wear grade is a comparative rating
based on the wear rate of the t ire when tested
u nder controlled conditions on a specified
government test course .
For example, a tire graded 1S0 would wear
one and one ha lf (11/2) times as well on the
gover nment course as a t ire graded 100 .
The relative performance of tires depends upon the actual conditions of their use, how­
ever, and may depa rt s ignificantly from the
norm due to va ria tions in d riving hab its, serv­
ice practices and differences in road character-
istics and climate.

Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If differen t rims are fit­
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -eve n if it
i s the same model
¢ page 266.
_&. WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the threads in the wheel hubs clean so the
whee l bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose wh ile driving if greased or
o iled, even if tightened to the specif ied
torque .
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
-Always maintain the correct tighten ing
torque for the wheel bo lts to reduce the
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
cl e is moving.
If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
Q;) Note
The spec ified torque fo r the wheel bo lts is
90 ft lbs. (120 Nm) with a tolerance of
± 7,4 ft lbs.(± 10 Nm). Torque wheel bo lts

Low aspect ratio tires
Your Aud i is factory -equ ipped w ith low aspect
ratio tires . These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and hand ling under a var iety o f driving cond i­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numeral of
55 or l ess in the tire's s ize
designation. The numera l rep resents the ra tio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
T he performance of low-a spe ct- ra tio tire s is
p ar tic ul ar ly se nsi tiv e to i mprop er i nfl ation
pre ssure. It is the refo re important that low
a spect ratio t ires are inflated to the specified
pr ess ure and that th e inflation pr essur e is
r e gula rly ch ecked and maintain ed. Tir e pre s­
s ure s should b e check ed at l east once a
m onth and alwa ys befo re a long trip
¢ page 228, Checking tire pressure.
What you c an do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, g ull ies
o r ridges on the road, pa rticularly if the tire is
u nderinflated.
In orde r to minimize the occurrence of impact
damage to the tires of your vehicle, we recom ­
mend that you observe the following p reca u­
tions:
- Always ma inta in recommended inflation
pressu res. Check your tire pressure eve ry
2,000 miles (3,000 km) and add air if neces-
sary . .., •
