252 Tir es and whe els
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 veh icle -
for example with winter tires - only use
the spare tire for a short period of time
and dr ive with extra care . Refit the nor­
ma l road wheel as soon as safely possi­
ble.
- Never drive faster than the maximum
speed for which the tires on your veh icle
are rated because ti res that a re driven
faster than their rated speed can fail
sudden ly .
- Overloading t ires cause heat build- up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- T emperature grades app ly to tires that
are properly inflated and not over o r un ­
derinflated .
- For technical reasons it is not a lways
possible to use wheels from other vehi­
cles -in some cases not even whee ls
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle whee ls, make sure that the air f low
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 t ires may only be used on vehi­
cles that were equipped with them at the
factory . The vehicle must have a chassis
designed for run flat tires . Incorrect use
of run flat tires can lead to vehicle dam­
age or acc idents. Check with an a uthor­
ized Audi dea le r or tire specialist to see if
yo ur vehicle can be equipped with run
flat tires. If run f lat tires are used, they
must be insta lled on all four wheels. Mix­
ing t ire types is not permitted .
- Fo r technical reasons , it is not genera lly
possib le to use the whee l rims from oth­
er vehicles. This can ho ld true for wheels
of the same veh icle type. - If the spare tire is different from the
tires that yo u 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 w ith
extra care. Replace the flat tire w ith the
tire matching the others on your vehicle
as soon as possib le .
- Never drive without the valve stern cap .
The valves cou ld get damaged .
@) For the sake of the environment
Dispose of o ld tires in accordance with the
local requirements .
Uniform tire quality grading
-Tread wear
- Traction AA AB C
- Tempe ra tu re ABC
Quality grades can be found whe re applicab le
on the tire sid e wall betw een tr ead shou ld er
a nd maximum section width
c> page 249,
fig. 188 .
For ex ample: Tread wear 200 , Tract ion AA ,
Temperatur e A.
All passenger car t ires must conform to Feder­
al Safety Requirements in add ition to these
grades.
Tread wear
T he tread wear grade is a comparative rating
based on the wear rate of the t ire when tes ted
u nder contro lled cond itions on a specified
government test course .
For example, a tire graded 150 would wear
one and one ha lf (11/2) times as well on the
government course as a tire graded 100.
T he relative performance of tires depends
upon the actual conditions of thei r use, how­
ever, and may depa rt s ignificantly from the
norm due to va riations in driving hab its, se rv­
ice practices and differences in road character -
istics and cl imat e. ..,.

Space-saving spare tire (compact spare
tire)*
A pplies to vehicles: with space-sav ing spa re tire
The spare tire/wheel is located in the luggage
compartment under the cargo floor cover. It
is intended for short-term use only.
F ig . 195 Spare t ire
Tak ing ou t the sp ar e whee l

Using the spare tire (compact spare tir e)
The compact spare tire is only intended for
emergenc ies until you can reach a repair shop .
Replace it as quickly as poss ible with a stand­
ard wheel and t ire.
There are some restrictions on the use of the
compact spare t ire . The compact spare t ire
has been des igned specifically fo r your type of
ve hicl e. It must not be swapped with a com­
pact spare t ire from another type of veh icle.
What do I d o now ? 261
Snow chains
For technical reasons, the use of snow cha ins
o n the compact spare tire is
not permitted .
If you do have to drive with snow chains and a
front tire fails, moun t the spare wheel wi th
ti re i nste ad of a rear tire. Install the snow
chains on the rear tire and use it to replace
the defective front tire .
A WARNING
-Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dicators.
- If the spare tire is more than 6 years old,
use it only in an emergency and with ex­
treme caution and careful driv ing.
- The spare tire is intended only for tem­
porary and short-term use. It s hould be
replaced as soon as poss ible with the
normal whee l and tire .
- After mounting the compact spare tire,
the t ire pressure must be checked as
soon as possible . T he tire pressu re of the
compact spare t ire must be
4.2 ba r; oth­
erwise, you risk having an a ccident.
- Do not dr ive faste r than
SO mph (80 km/
h). You ris k having a n accide nt.
- Avoid full-throttle acceleration, heavy
brak ing, and fast corne ring . You risk hav­
i n g an accident .
- Never d rive using more than one spare
wheel and t ire. You r is k having an acci­
dent.
- Normal summer or winter t ires must not
be mou nted on the compact spare w heel
nm.
- For t echnical reasons, the use of tir e
chains on the spa re tire is not permit ted .
I f it is ne cessary to drive with t ire chains,
the spare wheel must be mounte d on the
fro nt ax le in the event of a flat in a rear
tire. The newly available front whee l
must then be insta lled in place of the
rear whee l w ith the flat tire . Installing
the t ire cha in before mounting the whee l
and tire is recomme nded .

262 What do I do now ?
-Loose items in the passenger compar t­
ment can cause serious personal inj ury
during hard braking or in an acc ident.
- Never store the inflatable spa re tire or
jack and tools in the passenger com­
partment .
- Always s to re a ll jack ing equipmen t,
too ls, and the inflatab le spa re tire in
the l uggage compa rtment .
- Tighten the kn ur led retaining screw for
the inflatable spare tire sec urely.

Changing a wheel
Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang­
ing a wheel.
.,. After you experience a t ire failur e, pull the
car we ll away from mov ing traffic and try to
re ach
level ground before you stop ¢ .&,.
.. All passengers should lea ve th e car and
move to a safe location (for instance, b ehind
the guardrail) ¢

A WARNING
You o r your passengers could be i nju red
while changing a wheel if you do not fo l­
l ow these sa fety precaut ions:
- If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the eme rgency flashers on and use
-

other warning devices to alert other mo­
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed. When one
front wheel is lifted off the ground, plac­
ing the Automatic Transmission in "P"
(Park) will
not prevent the vehicle from
moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- After installing the spare wheel, make
sure that you replace the flat tire/wheel
in its storage area properly and tighten
the knurled retaining screw securely.
@ Tips
Before changing the wheel, you must acti·
vate the jacking mode, so that the auto­
matic controls for the Adaptive Air Sus­
pension do not make it more difficult to
lift the vehicle with the jack ¢
page 265.

A WARNING
Always read and follow all WARNINGS and
information¢ .&
in Raising the vehicle on
page 265
and ¢ page 267.
After changing a wheel
A wheel change is not complete without the
doing the following.
.. Store and secure the wheel you replaced in
the spare wheel well.
.. Replace the tools and the jack in their prop­
er location.
.. Check the
tire pressure on the spare wheel
immediately after mounting it.
.. As soon as possible, have the
tightening
torques
on all wheel bolts checked with a
torque wrench. The correct tightening tor­
que is 90
ft lb (120 Nm).
.. Have the flat tire
replaced as soon as possi­
ble .
(D Tips
-If you notice that the wheel bolts a re
corroded and difficult to turn while
changing a tire, they should be replaced
before you check the tightening torque.
- Drive at reduced speed until you have the
tightening torques checked.
