tire failure and loss of
control.
-Excessive speed and/over­ loading can cause heat
build -up, sudden tire failure
and loss of control.
-If the tire pressure is too low or too high, the tires
will wear prematurely and
the vehicle will not handle
well.
-If the tire is not flat and you do not have to change a
wheel immediately, drive at
reduced speed to the near­
est service station to check
the tire pressure and add air as required.
(D Note
Driving without valve stem
caps can cause damage to
the tire valves. To prevent
this, always make sure that
factory installed valve stem caps on all wheels are secure­
ly mounted on the valve.
@ For the sake of the environment
Underinflated tires will also
increase the fuel consump­
tion.

Tires and vehicle load limits
'
There are limits to the amount of load or weight that any vehi­
cle and any tire can carry. Ave­
hicle that is overloaded will not
handle well and is more diffi­
cult to stop. Overloading can
not only lead to loss of vehicle
control, but can also damage important parts of the vehicle
and can lead to sudden tire fail­
ure, including a blowout and
sudden deflation that can cause
the vehicle to crash.
Your safety and that of your passengers also depends on
making sure that load limits are
not exceeded. Vehicle load in­
cludes everybody and every­
thing in and on the vehicle .
These load limits are technical­ ly referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the
weight of the basic vehicle, all
factory installed accessories, a
full tank of fuel, oil, coolant and other fluids plus maximum ""

Tire pressure indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig. 205 Display: underinflation warning
Fig. 206 Display: System malfunction
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­ ference and vibration characteristics of the in­
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the instru­
ment cluster with a warning symbol
rD] and a
message
c:> fig . 205.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­
justed (e.g. when switching between partial
and fu ll load pressure) or after changing or re­
placing a tire on your vehicle
c:> page272 . The
TPMS indicator only monitors the tire pres­
sure that you have previously stored. You can
find the recommended tire pressures for your
vehicle on the label on driver's side 8-pillar
c:>page247.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,

- the tire has structural damage,
- the tire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset

Ifljl appears
after switching the ignition on or while driving
¢
fig. 206 and the indicator light rD] in the in­
strument cluster blinks for approximately one
minute and then stays on, there is a system
malfunction. Attempt to store the correct tire
pressure
c:> page 272. If the indicator light
does not turn off or if it turns on shortly
thereafter, immediately drive your vehicle to
an authorized Audi dealer or authorized repair
facility to have the malfunction corrected.
_& 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 247 . Driving on a
significantly 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.
.

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.

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction .
Using a sp are t ire wi th a tread pattern
int ended fo r use in a specific dir ect ion
When us ing a spare tire w ith a tread patte rn
intended for use in a specific direction, please
note the following:
- The direction of rotation is marked by an ar­
row on the side of the tire.
- If the spare t ire has to be installed in the in­
correct direction, use the spare tire only
temporarily since the t ire will not be able to
achieve its optimum performance character­
ist ics with rega rd to aquaplaning, noise and
wea r.
- We recommend that you pay particular at­
tent ion to this fact du ring wet weather and
that you adjust your speed to matc h road
conditions.
- Replace the flat tire w ith a new one and
have it installed on your vehicle as soon as
possible to restore the handling advantages
of a unidirectiona l tire .
