run flat tires. If run flat tire s
are u sed , they mu st be in­
stalled on all four wheel s.
Mixing tire types is not per­
mitted.
@) Note
-For technical reasons, it is
not generally possible to
use the wheel rims from
other 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 vehicle
(for example winter tires or
wide prof ile tires), then use
the spare tire for a short pe­
riod of time only and drive
with extra care. Replace the
flat tire with the tire match­ ing the others on your vehi­
cle 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 accord­
ance w ith the local require­
ments.
Uniform tire quality grading

- Traction AA A B C
- Temperature ABC
Quality g rades can be foun d where applicab le
on the t ire s ide wall between t read sho ulder

For example: Tread wear 200 , Traction AA,
Temperature A.
All passenger car t ires must con fo rm to Feder ­
al Safety Req uirements in ad dition to these
grades.
Tread wear
T he tread we ar g rade is a c omp arative r ati ng
based on the wea r ra te of the t ire when tes ted
u nder con tro lled cond itions o n a specifie d
government test course .
F or example, a tire gr aded 1S 0 wo uld wear

government course as a ti re g raded 100.
T he re lative per formance of tires depends

ever, and m ay depart s ignificantly from the
no rm due to va ria tions i n driving hab its, se rv ­
ice p ractices and differences in road character­
ist ics and cl imate.
Traction
T he trac tio n gr ad es, fro m highest to lowest,
are AA, A, Ban d

ti re 's ability to stop on wet pavement as
measured under cont rolled conditions on
specified government test surfaces of aspha lt
and concrete. A t ire mar ked C may have poor

Temperature
The temperature grades are A (the highest),

272 Tires and wheels -Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor
indicator may be delayed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle.
- 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
c:> page 260. 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
adapt the pressures to the current load <=>page 247.
• Switch on the ignition.
• Select in the MMI: !CAR !function button>
(Car)* systems control button > Servicing &
checks > Tire pressure monitoring > Store
tire pressures> Yes, store now.
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 hov e 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 onl y be li~ed at the lif ting
points illu stra ted.
