brake AUDI RS7 SPORTBACK 2014 Workshop Manual

236 Tire s and whee ls
including a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passenge rs a lso
depends on making s ure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle. These
load limits are techn ically referred to as the
vehicle's
Gr oss Veh icl e W eight R ating
("GVWR").
The "GVWR" includes the weight of the basic
ve hicle, all factory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
i ntended to carry ("seating capacity") with a n
assumed weight of 150 lbs (68 kg) for each
passenger at a des ignated seat ing pos ition
and the tota l we ight of any luggage in the ve­
h icle.
The
Gro ss Axle Weight Rating ("GAWR") is
the maximum load that can be app lied at each
of the vehicle's two axles .
The G ross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance st icker labe l located on the
driver 's side B-p illar. Your A udi has 4 seating
positions, 2 in the front and 2 in the rear for
total seating capacity of 4. Each seating posi­
tion has a safety belt
9 page 133, Safety
belts.
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the tota l weight of whatever is being car­
ried in the vehicle is limited. The more passen­
gers in the veh icle or passengers who are
heav ier than the standard weights assumed
mean that less weight can be carried as lug­
gage.
The tire pressure label on your Audi also lists
the maximum combined weight of all of the
occupants and luggage or other cargo that
the veh icle can carry . For the location of the
l abe l

A WARNING
Overloading a vehicle can cause loss of ve­
h icle contro l, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash.
- Always make sure that the total lo ad be­
ing transpor ted does not make the veh i­
cle heavier than the vehicle's Gross Vehi ­
cle Weight Rating.
Determining correct load limit

Steps for Determining
Correct Load Limit

238 Tires and wheels
symbols) indicate the positions of the tread
wear indicators. Worn tires must be replaced. Different figures may apply in other countries
c::> & .
Tire pressure
Incorrect tire p ressure causes premature wear
and can cause sudden tire blow-out. For this
reason, tire pressure must be checked at least
once a month
c::> page 234.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For all four tir es on your vehicle to have the
same se rv ice life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing:
- T ire rotation inte rva ls may differ from the
vehicle serv ice intervals outlined in your
Warranty
& Maintenance booklet.
- T he longer one tire is used in one location
on the vehicle, the more it wears at certa in
points; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals.
- Vehicles with front-wheel drive experience
more tread wear on the front whee ls com­
pared to all-whee l drive (quattro).
- Please rotate ti res as shown
c::> fig. 198.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 2 59.
Wheel balancing
The wheels on new vehicles are balanced .
Ho wever, various situations during everyday
driving can cause them to become unbal­
anced, resu lting in vibrations you can usually
feel through the steering wheel.
Unba lanced wheels must be rebalanced to
avoid excessive wea r on steering, suspension
and tires . A wheel must a lso be rebalanced
when a new tire is installed. Incorrect wheel alignment
Incorrect
wheel alignment can cause exces­
sive tire wear, impairing the safety of the vehi ­
cle. If tires show excessive wear, have the
wheel alignment checked by an a uthorized
Audi dealer or qualified workshop.
All-wheel drive
Vehicles with quattro must always have tires
of the same size, construction and tread type.
For details see
c::>page 195.
_8 WARNING
-Sudden tire fa ilure 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 t ires 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, o il, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fai l suddenly, especially at high
speeds. Tires that are more than 6 yea rs
old can only be used in an emergency
and then w ith specia l care and at lower
speeds.
- Never mount used tires on your veh icle if
you are not sure of their "previous histo­
ry." O ld used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control.

manufacturers also must indicate the materi­
als in the tire, which include steel, nylon, pol­
yester, and others.

under normal driving conditions.
_& WARNING ,...__._
- Using incorrect or unmatched tires and/
or whee ls or improper tire and whee l
combinations can lead to loss of contro l,
co llision and serious persona l injury.
- Always use tires, rims and wheel bo lts
that meet the specifications of original
factory-installed tires or other combina­ t ions that have been spec ifically ap­
proved by the vehicle manufacturer.
- 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 su re of their "previous histo­
ry." Old used ti res may have been dam­
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss of vehicle control.
- All four wheels must be fitted with radia l
tires of the same type, size (rolling cir­ c u mference) and the same tread pattern.
Driving with different tires red uces veh i­
cle handling and can lead to a loss of
control.
Tire s an d wheel s 241
-If the replacement tire is not the same as
the t ires that are mounted on the veh icle
- for example with winter tires - only use
the replacement tire for a short per iod of
time and drive with extra care . Refit the
normal road whee l as soon as safely pos­
sible.
- Never drive faster than the max imum
speed for which the tires on you r vehicle
a re rated because tires that are dr iven
faster than thei r rated speed ca n fa il
suddenly .
- Ove rloading tires ca use heat build-up,
sudden tire fa ilure, including a blowou t
and sudden deflation and loss of cont ro l.
- Temperature grades apply to ti res that
are properly inflated and not over or un ­
derinf lated .
- F or technical reasons it is not always
possible to use whee ls from other
vehicles -in some cases not even whee ls
from the same veh icle mode l.
- If you install wheel trim discs on the ve ­
hicle wheels, make sure that the air flow
to the brakes is not b locked. Reduced air­
flow to the brakes can them to overheat, increas ing stopping d istances and caus­
ing a co llision.
- Run flat tires may only be used on
veh icles that were equipped with them
at the factory . The veh icle must have a
chassis designed for run flat tires . Incor­
rect use of ru n flat ti res can lead to vehi­
cle damage or accide nts. Che ck with an
author ized Audi dealer or tire spe cialist
to see if your vehicle can be eq uipped
with run flat tires . If run flat tires are
used, they must be installed on all four
wheels. Mixing tire types is not permit­
ted.
@ Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth­
er veh icles. Th is can hold tr ue for wheels
of the same vehicle type. .,..

252 What do I do now?
(D Note
Do not use commerc ia lly available tire
sealants . The electrical components of the
tire pressure mon itoring system will no
longer work properly.
@ For the sake of the environment
Used sealant bottles can be dropped off at
a recycl ing facility.
@ Tips
- If sealant has run out, allow it to dry.
Then you can peel it off.
- Have the tire sealant replaced every 4
years at a dea lership.
Preliminary steps
Some preliminary steps ore necessary for tire
repair.
.,. If you have a fla t t ire, park the veh icle as far
as possible from moving traffic.

parking brake firmly .
.,. Move the
selector lever to the P position .
.,. Check whether a repair using the Tire Mobili­
ty System is possible Q page 251, General
and safety pointers .
.,. Have all passengers leave the vehicle and
stay away from the danger zone
q ,& .
.,. Take the s ealant bottle and the electric air
pump
from the luggage compartment un­
der the floor.
.,. Remove the "max . SO mph" (80 km/h) stick­
er from the sealant bottle and aff ix it to the
instrument cluster in the driver's view .
A WARNING
-Turn the hazard flashers on and set up
the warning triangle* if you have a flat
tire in moving traffic. In this way you pro­
tect you rs elf and other road users .
- Make sure that all passengers are in a
safe place, out of the danger zone (for
example, behind a guard ra il).

@ Tips
The disc harged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charg ing the
battery, never connect the negative
ground cable to the batte ry negat ive post
because the ba tte ry manager system must
be ab le to detect the battery's state of
charge. Always connect the negative
g round cab le to the negative ground pos t
of t he battery manager cont ro l unit.
Use of jumper cables
Make sure to connect the jumper coble
clomps in exactly the order described b elow!
