brake AUDI RS7 SPORTBACK 2016 Workshop 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 ...

that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle 's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­ sengers in the vehicle or passen ­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver 's side 8-pillar
¢ page 228,
fig. 192.
& WARNING
-
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than
your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
Wheels
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to­
tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer - does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload­ ed.
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCU-
PANTS AND CARGO SHOULD .,.

Preliminary steps
Some preliminary steps are necessary for tire re­
pair.
• If you have a flat tire, park the vehicle as far as
poss ible from moving traffic.
• Apply the
parking brake firmly .
• Move the
selector lever to the P position .
• Check whether a repair using the Tire Mobility
System is possible ¢
page 239, General and
safety pointers.
• Have all passengers leave the vehicle and stay
away from the danger zone
~ _& .
• Take the sealant bottle and the electric air
pump from the luggage compartment under
the floor
¢page 239, fig. 197 .
• Remove the "max . SO mph" (80 km/h) sticker
from the sealant bottle and affix it to the in ­
strument cluster in the dr iver's view .
..&, 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 protect your­
self and other road users.
