Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires -only use
the spare tire for a short period of time and drive with extra care. Refit the nor­
mal road wheel as soon as safely possi­
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un­
deri nflated.
- For technical reasons it is not always
possible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle wheels, make sure that the air flow
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 with them at the factory . The vehicle must have a
chassis designed for run flat tires. Incor­
rect use of run flat tires can lead to vehi­
cle damage or accidents. Check with an
authorized Audi dealer or tire specialist
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. Mixing tire types is not permit­
ted.
(D Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth-
Tires and wheels 259
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged .
(® For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
-Tread wear
- Tract ion AA A B C
- Temperature AB C
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
c;, page 256,
fig. 212.
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder­
al Safety Requirements in addition to these
grades.
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
government test course.
For example, a tire graded ISO would wear
one and one half (11/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of their use, how­
ever, and may depart significantly from the
norm due to variations in driving habits, serv­
ice practices and differences in road character-
istics and climate.

A WARNING ,~
- If the tire pressure indicator appears in
the instrument cluster display, one or
more of your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
pressure label¢
page 249. Driving on a
signif icantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to impair the vehicle's handling and stop­
ping ability .
- The driver is responsible for maintaining the correct tire pressures. You must check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi­
cator may be delayed.
-Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle.
.
(0 Tips
- The tire pressure monitoring system may
stop working when there is an ESC mal­
function.
- Using snow chains may result in a system
malfunction .
- The tire pressure monitoring system on your Audi was developed using tires with
the "AO" or "RO" identification on the
tire sidewall
¢page 256. We recom­
mend using these tires.
Reset tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
MMI.
.,. Before storing the new tire pressures, check
that the current pressures on all four tires
correspond to the specified values and
Tires and wheels 265
adapt the pressures to the current load
¢page 249 .
.,. Switch on the ignition.
.,. Select in the MMI:
ICARI function button >
Car systems control button > Servicing &
checks > Tire pressure monitoring > Store
tire pressures > Yes, store now.
(D Tips
Do not store the tire pressure if there are
snow chains on the tire. Otherwise, a sys ­
tem malfunction may occur .

@ Tips
Check carefully to make sure the hook-up
is secure before moving the car up the flat­
bed truck ramp.
Vehicle transport
Whenever you hove your vehicle transported,
be sure to note the following:
(D Note
Mount the tie-down chains/cables over the
running surface (circumference) of the
tires. Never secure the vehicle by the axle,
the suspension struts or the front or rear
towline eye. For technical reasons, the
pressure in the suspension struts may
change du ring the transport and this will
adve rsely affect vehicle handling.
Lifting vehicle
Lifting with workshop hoist and with
floor jack
The vehicle may only be li~ed at the lifting
points illustrated.

• Read and heed WARNING Q ,&. .
Emergenc y situ ation s 285
• Activate the vehicle jack mode in the MMI :
!CAR I function button > Ca r system s control
button>
Ser vici ng & ch ecks > Air su sp. :
jack mo de > On .
• Locate lifting points Q fig. 242 and
¢fig. 243.
• Adjust lifting arms of wo rkshop hoist o r
floor jack to match veh icle lifting points.
• Insert a rubber pad be tween the floo r jack/
workshop hoist and the lift ing po ints .
The vehicle jack mode must be activated so
that the automat ic adjustment of the Adap­
tive Ai r Suspens ion does not make it more dif­
fic ult to raise the vehicle with the floor ja ck.
If you mu st l ift your vehicle with a fl oor jack
t o wo rk underneath , be sure the vehi cle i s
s af ely s upported on stand s intended for thi s
purpose.
Front lifting point
The lifting point is located on the floor pan re­
i nforcement about at the same leve l as the
jac k mounting point
Q fig . 242. Do not lift
t h e v ehi cle at the verti cal sill reinf orcement .
Rear lifting point
The lifting point is located o n the vert ical rein ­
forcement of the lower sill for the on-board
jack ¢
fig. 243 .
Lifting with vehicle jack
Refer to ¢ page 2 72 .
&_ WARNING ,-~
-To reduce the risk of serious injury and
vehicle damage .
- Always lift the vehicle only at the spe­
c ia l workshop ho ist and floor jack lift
points illustrated
¢fig . 242 and
¢ fig. 243 .
- Fail ure to lift the vehicle at these
po ints co uld cause the vehicle to tilt or
fall from a lift if there is a change in ve­
hicle weight distribution and balance.
This might happen, for example, when h eavy components such as the eng ine
block or transmission are removed.
