196 Tires and wheels
wheels you have to adjust the tire pressures
on all wheels.
A WARNING
Incorrect tire pressures and/or underinfla
tion can lead sudden tire failure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
RI] appears in
the instrument cluster, stop and inspect
the tires .
- Incorrect tire pressure and/or underinfla
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping ability .
- Incorrect tire pressures and/or underin flation can also lead to sudden tire fail
ure, including a blowout and sudden de
flation, causing loss of vehicle control.
- The driver is responsible for the correct
tire pressures for all tires on the vehicle .
The applicable pressure values are locat
ed on a sticker on the driver's side 8-pil
lar.
- Only when all tires on the vehicle are fil
led to the correct pressure, the tire pres
sure monitoring system can work cor
rectly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver
observe the specified tire pressure values
for the tires and the correct pressures for
the function of the tire pressure monitor
ing system .
- Always inflate tires to the recommended
and correct tire pressure before driving
off .
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading 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 nearest service sta
tion 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 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 will not handle
well and is more difficult 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 failure, in cluding 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 includes everybody
and everything in and on the vehicle . These
load limits are technically 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 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 total weight of any luggage in the ve-
hicle. ..,_

208 Tir es and whee ls
- The tire pressure monitoring system
helps the driver to keep an eye on tire
pressures. But the driver st ill has the re
sponsibility for maintaining the correct
tire pressure.
- Tire pressure must only be adjusted
when the temperature of the tires is
about the same as ambient air tempera
ture.
- When tires are replaced, the sensors and
valves should not be exchanged . The
valve core, nut, valve sealing and seal
washer (rep lacement kit) needs to be re
placed. If necessary, the valve and the
whee l electronics have to be rep laced.
- The tire pressure monitoring system on
your Audi was calibrated us ing tires w ith
"RO" identification. We recommend us
i ng these tires.
- If you should put different whee ls and
ti res on yo ur vehicle (e.g. w inter wheels
and tires), yo u m ust be certain that the
whee ls and tires are compatible with the
tire pressure monitoring system . Other
wise the system w ill reg ister a ma lfunc
tion and a fault message will be d is
played . For more information, contact
your authorized Audi dealer .

Programming a new set of tires
App lies to vehicles: with tire pressure monitor ing system
When driving with a new set of ti res, you can
p rogram them to the t ire pres sure monitoring
system using the menu disp lay.
"' Turn the ign ition on .
"' Se lect the menu :
Set > Tir e pr ess ure >
Wheel chang e.
"' Confirm that you wo uld like to begin the
programming p rocess. The message
Wheel
s ens ors are being in it iali sed. Thi s m ay ta ke
a fe w minute s .. .
appears in the instrument
cluster disp lay. You can switch between programmed tire sets
at any time without reinitializing the system .
(D Tips
If the programming process was not com
pleted successfully, the message
Wheel

appea rs in
the disp lay and the
11118' indicator light
turns on. If this happens, repeat the pro
cedure .

Tightening wheel bolts
.,. Fit the wh eel b olt wrench ove r the wheel
bolt and push it down as far as it will go
1l.
.,. Close your grip around the
end of the
wrenc h handle fo r maximum torque and
turn each wheel bolt
clockwi se u nti l it sits
t ight.
H ave the
tightening torque of the whee l bolts
checked as soon as possible with a torque
wrench . It shou ld be 120 Nm.
Chec k the
tire pre ssure as soon as possible.
Return the vehicle tool kit to its proper place.
A WARNING
Loose ning t he wheel bo lts is prohib ited;
da nger of an accident!
@ Tips
- Never try and use the hexagona l socke t
i n the handle of the screwdr iver to loos
en or tighten the w heel bolts.
- If yo u have dete rm ined t hat wheel bolts
a re cor roded and difficult to t urn, the
bo lts must be rep laced befo re checking
the to rque.
- Unti l the tig hte ning torque is checked,
d rive at redu ced speeds as a pre caution.
Notes on wheel change
Pl ease read the information¢ page 199, New
tires and replacing tires and wheels,
if you are
going to use a spare tire which is different
from the tires on your veh icle.
Afte r you change a tire:
- Check the tire pressure on the spare imme
dia tely after mounting.
- Have the whee l bolt t ightening torque
chec ked w ith a torq ue wrench as soon as
poss ible by your author ized A udi dealer or a
qu alified service sta tion.
1 ) You need th e appropr iate adapter to tighte n the a nti
t h eft wheel bolts
c:, page 216.
What do I do now? 219
- With stee l and alloy whee l rims, the whee l
bolts are correctly tightened at a torque of
90 ft lb (120 Nm) .
- If you notice while changing a tire that the
wheel bo lts are corroded and difficu lt to
turn, then they should be rep laced before
you check the tightening torque.
- Replace the flat tire with a new one and
have it installed on your vehicle as soon as
possible. Remount the wheel cover.
Until then , d riv e with e xtra care and at re
duced speeds.
A WARNING
- If you are going to equ ip your vehicle
with tires or rims which differ from those
which were facto ry installed, then be
sure to read the information ¢
page 199,

wheels.
- Always sto re the tools secu rely in lug
