used today are underinflated just by looking
at them.
Therefore, be sure to check tire pressures at l eas t once a mon th and always before going
on a long trip. Make sure to take the number
of people and the amount of luggage into ac­
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long." See ¢
page 220, Tires and vehicle
load limits
for more important information .
A lways use an accurate tire pressure gauge
when check ing and adjusting inflation pres­
sures . Check all of the tires and be sure not to
forget the spare t ire . If the pressure in any tire
is too high when the tire is "cold," let air out
of the tire slowly with the edge of the t ire
gauge and keep checking the pressure until
you reach the p ress ure th at is cor rect for the
l oad (passengers and luggage) and kind of
driving you plan to do .
I f the p ressu re in any tire is too low , note the
d ifference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your vehicle as listed on the on
your veh icle and in this manual and the kind
of dr iving you p lan to do.
Never e xceed the m aximum inflation pre s­
su re li sted on th e tir e side wall for any rea ­
son.
Remember that the vehicle manufacturer, not
the tire manufacturer, determines the co rrect
tire p ressure for the tires on your vehicle .
It is important to check the tire pressure when
the tires are cold .
- Read the requ ired ti re p ressu re from the tire
pressure label. On USA veh icles, the t ire
pressure label is located on driver's side 8-
pillar . On Canada vehicles, the tire pressure
label is located either on the driver's side 8-
pillar or inside the fuel fi ller flap.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure ga uge on the valve.
Tire s an d wheel s 219
- The tire pressures should only be checked
and adj usted when the tires are co ld . The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reinstall the valve stem cap on the va lve.
When should I check the tir e pressu re?
T he co rrect tire pressu re is especially impor ­
tant a t high speeds. The pressure should
therefore be checked at least once a month
and always before starting a jo urney . Do not
forget to check the tire pressure for the spare
whee l
¢page 234.
When should I adjust the tire pres sur es?
Adjus t the t ire press ure to the load you a re
carrying . After changing a whee l
or rep lacing
whee ls you have to adjust the tire pressu res
on all whee ls. In addition, yo u m ust then initi­
ali ze the new t ire pressures in the tire pres­
sure monitoring system*¢
page 230.
A WARNING
...---
Incorrect tire pressures and/or underinfla-
tion can lead sudden tire fa ilure, loss of
control, collision, serio us personal injury
or even death.
- When the warning symbol
ti] appears in
the instrument cluster, stop and inspect
the t ires.
- Inco rrect tire pressure and/or underinfla­
tion can cause increased tire wea r and
can affect the hand ling of the vehicle and
s topping abi lity.
- I nco rrect tire pressures and/or unde rin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and sudden de­
flation, ca using loss of vehicle contro l.
- The driver is responsib le for the correc t
tire pressures for all tires on the veh icle.
The applicable pressure values are locat­
ed on a sticker on the dr iver's side 8-pil­
lar or on the ins ide of the fuel filler flap. •

226 Tires and wheels
and drive with extra care. Refit the nor­
mal road wheel as soon as safely possi­
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that are properly inflated and not over or un­
derinflated .
- For technical reasons it is not always
possible to use wheels from other vehi­
cles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle wheels , make sure that the air flow
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 tires 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 and a factory­
installed tire pressure monitoring sys­
tem* that indicates a loss of tire pres­
sure . Incorrect use of run flat tires can
lead to vehicle damage or accidents .
Check with an authorized Audi dealer or
tire specialist to see if your vehicle can be
equipped with run flat tires . If run flat
tires are used, they must be installed on
all four wheels. Mixing tire types is not
permitted .
(D Note
-For technical reasons, it is not generally
possible to use the wheel rims from oth­
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare ti re is different from the
tires that you 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 with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- If you put different wheels and tires on
your vehicle (e .g. winter wheels and
tires), you must be certain that the
wheels and tires are compatible with the
tire pressure monitoring system* . Other ­
wise the system will register a malfunc­
tion and a fault message will be dis­
played. For more information, contact
your authorized Audi dealer.
- Never drive without the valve stem cap .
The valves could get damaged .
@ For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
¢ page 223,
fig. 171 .
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder­
al Safety Requirements in addition to these
grades .
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
For example, a tire graded 150 would wear
one and one half (11/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart significantly from the
ll-

228 Tires and wheels
The speed rating letter code( ¢ page 224) is
on the side wall of the tire
¢ page 223.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off. Never drive faster
than the speed permitted for your specific
winter tires. This will cause damage to the
tires leading to an accident and serious
personal injury to you and your passen­
gers.
A WARNING I>=
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire failure in­
cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks . Al­
ways remember :
- When braking , an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes . Ask your
authorized Audi dealer on which tire sizes snow chains can be used.
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.53 inch
(13 .5 mm) , including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
¢ (!) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A WARNING
=
Using the wrong snow chains for your vehi-
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions provided by the snow chain manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
(D Note
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily .
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so. ..,.

b ac k in pl ace under nea th t he floo r pan el in
t he luggag e comp artmen t.
Note: some of the on -board items listed
above are provided on certain mode ls only or
are optiona l extras.
A WARNING
-Improper use of the vehicle jack can cause
serious personal injuries.
- Using a bumper jack to raise the vehicle
will damage the bumper system. The
jack may slip, caus ing injury.
- Never support your vehicle on c inder
b locks, br icks or other objects. These
may not be able to support the load and
could cause injury when they fail.
- Never start or run the eng ine while the
veh icle is supported by the jack.
- If you must work under the veh icle, al­
ways use safety stands specifically de­ signed fo r th is purpose.
- Never try and use the hexagonal socket
in the handle of the screwdriver to loos­
en or tighten the whee l bolts.
- Always make sure the spare tire and even
a flat tire are secured in place and not
loose, otherwise they cou ld fly forward,
causing pe rsonal i njury to passengers in
the vehicle in an accident or sudden ma­
neuver.
- Neve r use the ja ck supplied with your Au­
d i on another vehicle, particularly on a
heav ier one. The jack is only s uitable for
use on the vehicle it came with.
Compact spare wheel
Applies to veh icles: w ith compact spare whee l
The compact spare wheel is only intended to
be used for a short time.
Fig . 180 Compact spare wheel in the wheel well

236 What do I do now?
-After installing the compact spare wheel,
the tire inflation pressure should be
checked and, if necessary, increased to
60 psi (4.2 bar).
- The load carrying capacity is marked on
the tire sidewalls and must not be ex ­
ceeded.
- After installing the compact spare wheel,
make sure that you remount the flat tire
in its storage area properly.
- The compact spare tire should be proper­
ly remounted in its storage area as soon
as the standard road tire can be re­ placed .
- Because the compact spare tire was spe­
cifically designed for your vehicle, it must not be used on any other vehicle .
Likewise, compact spare wheels from
other vehicles must not be used on your
vehicle.
- The compact spare tire must not be
mounted on any other wheels, nor must
standard tires, snow tires, wheel covers
or trim rings be used with the compact
spare wheel. If such use is attempted,
damage to these items or other vehicle
components may occur .
(D Tips
Check the inflation pressure of the com­
pact spare tire (60 psi/4.2 bar) periodically
to keep the tire ready for use.
Wheel change
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 tire failure, pull the
car well away from moving traffic and try to
reach
level ground before you stop c:> ,&. .
.. All passengers should leave the car and
move to a safe location (for instance, behind
the guardrail)
c:> _&. .
.. Apply the parking brake firmly c:> _&. .
.. Move selector lever to position Pon an au­
tomatic transmission ; put manual transmis­
sion in
first gear c:> _&..
.. If you are towing a trailer : unhitch the trail­
e r from your vehicle.
.. Take the
tool and the spare tire c:> page 234
out of the luggage compartment .
.&, WARNING
You or your passengers could be injured
while changing a wheel if you do not fol­
low these safety precautions:
- If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the emergency flasher 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 roadway 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) , or engaging a gear in a manual
transmission 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 remount the flat tire/wheel
in its storage area properly and tighten
the knurled retaining screw securely.
