238 Tires and wheels
-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 nearest service sta­
t ion to check the tire pressure and add
air as required.
(D Note
Driving without valve stem caps can cause
damage to the tire va lves. To prevent this,
always make sure that facto ry installed
valve stem caps on all wheels are securely mounted on the valve.
@ For the sake of the environment
Underinflated tires will also increase the
fuel consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any tire can carry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overloading
can not only lead to loss of vehicle control,
but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the vehicle to crash .
Your safety and that of your passengers a lso
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle . These
load limits are techn ically 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 , oi l, coolant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
intended to carry ("seating capacity") with an
assumed weight of 150 lbs . (68 kg) for each
passenger at a designated seating position
and the tota l weight of any luggage in the ve- hide.
If you tow a trai ler, the weight of the
trailer hitch and the tongue weight of the loaded trailer must be included as part of the
vehicle load.
T he
Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles .
T he Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance sticker label located on the
driver's side B-pillar.Your Audi has 5 seating
positions, 2 in the front and 3 in the rear for
total seating capacity of 5. Each seating posi­
tion has a seat belt <=>
page 136, Safety belts .
The fact that there is an upper limit to yo ur
vehicle's Gross Vehicle Weight Rating means
that the to tal weight of wha tever is being car­
ried in the vehicle ( including the weight of a
tra iler hitch and the tongue weight of the
loaded trailer) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mean that less we ight can be carried as lug­
gage.
T he tire pressure label on your Audi also lists
the maximum combined weight of all of the
occupants and luggage or other cargo that
the vehicle can carry. For the location of the
label <=>page234 , fig.174.
A WARNING
-Overloading a vehicle can cause loss of ve-
hicle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more we ight than your vehicle
was des igned to carry will prevent the
veh icle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle with in a safe distance .
- Tires on a vehicle that has been overload­
ed can fail suddenly, incl uding a blowout
and sudden deflation, causing loss of
con trol and a crash .

When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­
ment or alternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct io ni ng
p roperly . Always check the T PMS malfunct ion
tellta le afte r replacing one or more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly .
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
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. 179 Display : underinflatio n warning
Using the ABS sensors, the tire pressure moni­
toring system compares the t ire tread circum­
ference and vibration characteristics of the in­
d iv idual tires . If the pressure decreases in one
or mo re tires, th is is indicated in the instru­
ment clus ter with a
IE warning symbol and a
message ¢
fig. 179. The driver message in the
display goes out after 5 seconds. The driver message can be displayed again by pressing
the
! SET ! button. If only one tire is affected,
the display will indicate its pos ition.
The tire pressure monitoring system must be reset via radio or MMI* each time the pres­
sures are adjusted (e.g . when switching be ­
tween partia l and full load pressure) or after
changing or replacing a t ire on your vehicle
¢

Tire tread circum ference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the t ire p ress ure in one or more tires is too
low,
- t he t ire has structural damage,
- the t ire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset

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.
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your vehicle or accidents
could also result.
@ Tips
- The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- 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 241. We recom­
mend using these tires.
Reset tire pressure monitoring system
Applies to vehicles: with tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
radio or MMI*.
11> Before resetting the TPMS, the current pres­
sures of all four tires must correspond to
the specified values. Adjust the tire pressure and reset the pressure in the tire pressure
monitoring system according to the load
you are carrying

-To he lp prevent the vehicle from moving
sudden ly and possibly slipping off the
jack, always fully set the parking brake and block the whee l diagona lly opposite
the wheel being cha nged with the fold­
ing chocks o r othe r objects. When one
front whee l is lifted off the g ro und, plac­
ing the A utomat ic Transm iss ion in "P"
(Park) wi ll
not prevent the vehi cle from
moving .
- Before you change a wheel, be su re the
ground is level and f irm . If necessa ry,
use a sturdy board under the jack.
- After installing the spare tire, make s ure
that you replace the flat ti re/wheel in its
storage area proper ly and tighten the
knur led retain ing screw securely .
Q;) Note
If you are changing the wheel on a steep
incline, use a rock or similar object to
block the opposite wheel to prevent the
veh icle from mov ing.
Obey all laws .

.,. Have the flat tire replaced as soon as possi­
ble .
(D Tips
-If you notice that the wheel bo lts a re
corroded and difficult to turn while
chang ing a tire, they should be replaced
before you check the tightening torque.
- Dr ive at reduced speed until you have the
tightening torques checked. •

@ Tips
-Never use the hexagonal socket in the
handle of the screwdriver to loosen or
tighten the wheel bolts.
- If a whee l bolt is very tight, you may find
it easier to loosen by carefully pushing
down on the end of the wheel bolt
wrench w ith
one foot only. As you do so,
hold on to the car to keep your ba lance
and take ca re not to slip.

t h e wheel bo lts .
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire w ith a t read patte rn
i ntended for use in a specific direction, please
n ot e th e follow ing:
- The direction of rotation is ma rked by an
ar­
row on the s ide of the t ire .
-If the spare t i re has to be installed in the in­
correct di rection, use the spare tire only
temporar ily since the t ire will not be able to
achieve its optimum perfo rma nce character­
ist ics with r ega rd to aquaplani ng, noise and
wea r.
- We recommend that you pay particular at ­
tent io n t o this fact du ring wet weathe r and
t h at you adjus t your spee d to matc h road
cond itio ns.
- Replace th e flat tire w ith a n ew one and
have it ins talled o n your ve hicle as soon as
poss ible to re st ore the hand ling advant ages
of a uni direct io na l t ire .
Notes on wheel changing
Please rea d the information ¢ page 241, New
tires and replacing tires and wheels
if you are
going to use a spare t ire which is different
from the tires on your ve hicle.
Afte r you change a tire :
-Check the tire pressure on the spare imme­
diately after installation . What do I do now? 257
- Have the wheel bolt tightening torque
checked with a torque wrench as soon a s
possible by your authorized Audi dealer or
a qualified workshop .
- With steel and alloy wheel rims , the wheel
bolts are cor rectly tightened at a torque of
90 ft lbs. (120 Nm ).
- If you notice that the wheel bolts are cor·
roded and difficult to turn while changing
a tire, they should be replaced before you
check the tightening torque .
- Replace the flat tire with a new one and
have it installed on your veh icle as soon as
possible. Remount the wheel cover.
Until then , drive with extra care and at re·
duced speeds.
