service AUDI RS7 SPORTBACK 2016 Service Manual

Wheels
-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 6 years old when abso­
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on your vehicle. Using them when
not permitted can lead to ve­
hicle damage or accidents.
-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
Fig. 191 Tire profile : treadwear indica­
tor
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.
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear
more quickly.
Treadwear indicator
The original tires on your vehicle have 1/16 inch (1.6 mm) high
"wear indicators" ¢fig.
191 ...

... N oi '-' ":
running across the tread. Marks
on the tire sidewall (for example "TWI" or other symbols) indicate
the positions of the tread wear in­
dicators.
The tires have reached the mini­ mum tread depth
l ) when they
have worn down to the treadwear
indicators . Replace the tires with
new ones
¢ ,1,. .
Wheel rotation
Rotating the wheels regularly is
recommended to ensure the tires
wear evenly. To rotate wheels, in­
stall the wheels from the rear
axle on the front axle and vice
versa. This will allow the tires to
have approximately the same
length of service life.
For unidirectiona l tires, make
sure the tires are installed accord ­
ing to the running direction indi­
cated on the tire sidewall
¢page 247 .
Hidden damage
Damage to tires and rims can of ­
ten occur in locations that are hidden. Unusual vibrations in the
vehicle or pulling to one side may
~ l) Obey any applicable regulations in your
~ country . ...
Wheels
indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed.
&_ WARNING
-
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can especially have a nega­ tive effect on handling, on the
risk aquaplaning when driving
through water, when driving
through curves and when brak­ ing, which increases the risk of
an accident.

NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
¢page 228, fig. 192.
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 sticker
¢ page 228, fig. 192.
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
be five 150 lbs. passengers in
your vehicle, the amount of available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 X 150) = 650
lbs.)
5. Determine the combined
weight of luggage and cargo being loaded on the vehicle.
That weight may not safely ex­ ceed the available cargo and
luggage load capacity calculat­
ed in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer
232
will be transferred to your ve­
hicle. Consult this manual to
determine how this reduces
the available cargo and lug­
gage load capacity of your vehi­
cle.
~check the tire sidewall
(¢page 218, fig. 190) to deter­
mine the designated load rating
for a specific tire.
Wheel bolts and rims '
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
disassemble them
9 &. .
_&. WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi­
cation, refer to
9 page 244, After changing a
wheel .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease .
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.

Winter tires
Winte r ti res s ignificantly improve the veh icle's
handling when driving in winter condit ions. Be­
cause of the ir construction (width, compound,
tread pattern), summer tires provide less trac­
tion o n ice and snow.
,.. Use w inter t ires on all fo ur wheels.
,.. Only use winter t ires that are approved for your
vehicle.
,.. Please note that the maximum permitted
speed may be lower with winter tires
9 &, . An
authorized Audi dealer or authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires.
,.. Check the tire press ure after installing wheels
9page 228.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .1 57 inch (4 mm). The character istics of winter
tires a lso dec rease great ly as the tire ages, re­
ga rdless of the remaining tread.
_& WARNING
- Never drive faster than the maxim um per­
mitted speed for your tires. This cou ld cause
the tires to heat up too much . Th is increases
the risk of an accident because it can cause
the tire to burst.
- Always adapt your dr iv ing to the road and
traff ic conditions. Drive carefully and reduce
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.
You ca n also use all season tires instead of
w inter t ires. Please note that in some coun­
tries where w inter t ires are required, only
w inter t ires with the
& symbol may be per­
m itted.

Wh eel s
Snow chains
Snow chains improve traction in the snow .
,.. On ly install snow chains on the front wheels.
,.. Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instruct ions from the manufacturer.
,.. Note the maximum permitted speed when dr iv­
ing wit h snow chains. Do not exceed 30 mph
(SO km/h) .
Snow cha ins not o nly improve the
driving in win­
te r road condit ions, but also the
braking.
Use of snow chains is only permitted with certa in
rim/tire comb inat ions due to technical reasons.
Check with an authorized Audi dealer or author­
ized Audi Service Facili ty to see if you may use
snow c ha ins.
You must remove the chains when driving on roads that are
free of snow . When roads are free
of snow, snow chai ns can impa ir handling and
damage the tires, and the chains will qu ic kl y be
dest royed.
_& WARNING ~
Using incorrect snow chains or ins tall ing snow
chains incorrect ly 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
covers* if the chains come into direct con ­
tact with them . Remove the wheel covers*
first. Use coated snow chains.
- Using snow c hains that add more than 0.4
inch ( 10.5 mm) of height can severely dam­
age the whee l housings and other vehicle
components.
- Do not insta ll and use snow chains if there is
a malfunction in the adapt ive a ir suspen­
sion*, because the vehicle he ight will be
very low. If you drive with snow chains any­
way, the wheel housings and other vehicle
components can be seve rely damaged.

Tread wear
The
tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov­
ernment test course.
F or example, a t ire graded 150 would wear one
and one half (11/2) times as well on the govern­
ment course as a tire graded 100 .
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate .
Traction
The
traction grades, from highest to lowest, are
AA, A, Band
C. Those grades represent the tire's
ability to stop on wet pavement as measured un ­
der controlled conditions on specified govern­ ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
¢ .&, .
Temperatur e
The
temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­ rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure
c:> .&, .
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard No. 109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING
-
The traction grade ass igned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
Wheels
A WARNING
The temperature grade for this tire is estab­ lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
i n comb inat ion, can cause heat buildu p and
possible tire failure.
A WARNING
-
-
Temperature grades apply to tires that are
properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
ill General notes
Each tire, including the spare (if provided),
shou ld be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla ­
t ion pressure for those tires).
As an added safety feature, your vehicle has been equipped with a tire pressure monitor ing system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­ ly under -inf lated. Accordingly, when the low t ire
pressure telltale illuminates, you should stop and
check your tires as soon as possib le, and inflate
them to the proper pressure . Driving on a signifi­
cant ly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fue l efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure telltale . .,.
235

Wheels
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operat ing properly . The TPMS mal­
function indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi ­
mately one minute and then remain cont inuously
illum inated . This sequence will continue upon
subsequent veh icle start-ups as long as the ma l­
function ex ists .
When the malfunct io n indicator is illuminated,
the system may not be able to detect or signal low tire pressu re as intended . TP MS ma lfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate ti res or
wheels on the vehicle that prevent the TPMS
from functioning properly. A lways check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
t hat the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Description
The tire pressure monitoring system monitors
the pressure in the four tires when driving .
The system uses sensors that measure the tem­
perature and pressure in the tires. The data is
sent from these sensors to the control module by
radio frequency .
The tire pressure monitoring system shows the current pressures and temperatures of the tires in the Infotainment system
c.>page 236. It also
compares the current t ire pressures with the
stored tire pressures and gives a warning in the
driver information system if the tire pressure is
d ifferent from what is stored¢
page 237.
The system does not detect if the stored t i re
pressures match the recommended tire pres­
sures. You must resave the tire pressures
c.> page 23 7:
-every time the tir e pressures change, for exam­
ple when the load in the vehicle changes,
- after replac ing a tire, or
- if wheels with new wheel sensors are used .
236
A WARNING ,_
- The tire pressure monitoring system ass ists
the dr iver in monitoring tire pressures. The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the t ire pressure when the
temperature of the tire is high . This could
result in serious damage to the tire and
even cause the tire to burst, increasing the
ris k of an accident.
- A tire with low pressure flexes more. This
heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent .
- The tire pressure monitoring system does
not warn about damage or defects in the
tire construction that could cause the tire to burst, for example. Inspect your t ires regu­
larly.
@ Tips
- If tires are replaced, the sensors/va lves do
not need to be removed or replaced. Just re­
placed the va lve stem and, if necessary, the
valve and the wheel electronics. If you have
questions, see your authorized Audi dealer
or authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors rep laced by an authorized Audi
dealer or authorized Audi Service Facility.
Display tire pressures/temperatures
Requirement: the ignition must be switched off.
.,. Select: the
I CARI funct ion button > Car systems
> Service & control > Tire pressure monitor >
Display tire pre ssure .
The current tire pressures are shown in green and
yellow numbers in the Infotainment system:
-green: the current tire pressure and the spec i­
fied tire pressure are approx imately the same .
-yellow: the current tire pressure is too low
compared to the spec ified t ire pressure .

The specified tire pressure is the last tire pres­
sure that was stored
¢ page 2 3 7 .
Note that the tire p ressure also depends on the
temperature of the t ire . Every 10 °C increase in
tire temperature results in the tire pressure in ­
creasing by approximate ly 0 .1 bar. The tire pres­
sure increases as the eng ine becomes warmer
while driving.
