&_ WARNING
"
-Do not use steel rims that are
17 inches or larger. Other­
wise, damage to the vehicle
and an accident could result.
-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 six 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.
Wheels
-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

tor
Tire wear
Check the tires regularly for wear.
-Inflat ion 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

The correct tire pressure for tires
installed at the factory is listed on
a
label ¢ fig. 284. The sticker is
located on the door pillar (driver's
side)¢ fig. 285. The location may
vary depending on the model.
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially loaded
¢ table
on page 353.
If driving the vehi­
cle when fully loaded, you must increase the tire pressure to the
maximum specified
pressure ¢,&. .
Checking/correcting tire
pressure
Wheels
.. Check the tire pressure at least
once per month and also check it before every long drive .
.. Always check the tire pressure
when the tires are
cold. Do not
reduce the pressure if it increas­
es when the tires are warm.
.. Check the label¢ fig. 285 for
the correct tire pressure based on vehicle load .
.. correct the tire pressure if nec ­
essary .
.. store the new tire pressure in
the Infotainment system
¢ page 361 .
.. Check the pressure in the spare
tire (compact spare tire)*. Al­
ways maintain the maximum
temperature that is specified for
the tire.
A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read and follow the important safe­
ty precautions
in¢ page 355,
Tires and vehicle load limits.
351

Wheels
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­
ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8-
pillar, always follow the specifica­
tion on the 8-pillar label
¢ page 351, fig. 284.
352
(i} For the sake of the environment
-Tire pressure that is too low
increases fuel consumption.
-Fuel consumption may also in­
crease when driving with the
comfort tire pressure is se­
lected .
(D Tips
Audi recommends using the
tire pressure specified for a
normal load
¢ table on
page 353
or for a full load
when the vehicle is partially loaded.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.
The following table lists recom­ mended tire pressures in cold
tires according to the load and
the size of the tires installed.

A 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.
-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
-
includ ing 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 -
356
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. Locat e the statement "THE
COMBINED WEIGHT OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS" on your vehicle's placard
(tire inflation pressure label)
Q page 351, fig. 285.
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 stick­
erQ page 351, fig. 285.
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.
