Wheels
and a special procedure. You must not repair or
disassemble them¢&. .
A WARNING
Wheel bolts that are tightened or repaired in
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi
cation, refer to ¢
page 22 7, After changing a
wheel .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Aud i
Service Facility . Never repair or disassemble
rims yourself, because this inc reases the risk
of an accident.
Winter tires
Winter tires s ignificantly improve the vehicle's
handling when driving in winter conditions . Be
cause of their construction (width, compound,
tread pattern), summer tires provide l ess trac
tion on ice and snow.
.,. Use winter tires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
q .&,. . An
authori zed Audi dealer or authori zed Audi Serv
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after install ing wheels
q page 215.
The effectiveness of winter tires is reduced great
ly when the tread is worn down to a depth of
0 .157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re
gardless of the remaining tread.
A WARNING
- Never drive faster than the maximum per
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
220
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun
tries where winter tires are required, only
winter tires w ith the ~ symbol may be per
mitted.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when dr iv
ing with snow chains. Do not exceed 30 mph (SO km/h).
Snow cha ins not only improve the
driving in win
ter road conditions, but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinat ions due to technical reasons .
Check with an author ized Audi dealer or author
ized Audi Service Facility to see if you may use
snow chains.
Use
fine-mesh snow chains. They must not add
more than 0.53 inch (13.5 mm) in height, includ
ing the chain lock.
You must remove the chains when driving on
roads that are
free of snow . When roads are free ..,.

damage the t ires, and t he chains will quickly b e
destroyed.
A WARNING
Using incorrect snow chains or installing snow
chains incorrect ly can result in loss of vehicle
co ntrol, which increases the risk of an acc i
dent .
Snow chains can damage the r ims/wheel cov
ers* if the chains come into d irect contact
w ith them . Remove the wheel covers* first.
Use coated snow chains .
@ Tips
When driving with snow cha ins, it may help to
switch on sport mode¢

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra
t io ti res. These t ires have been tho rough ly tested
a n d been se lected specifically fo r yo ur model for
t he ir superb performance, road feel and handling
under a variety o f driving conditions. Ask your au
thor ized Audi dealer for more details .
The low aspect ratio of these t ires is indicated by
a numera l of
55 or l ess in the tire 's size designa
tion . The numera l represents the rat io o f the
tire's sidewall height in relat ion to its tread width
expressed in pe rc e ntage. Conventional t ir e s hav e
a height/w idth rat io of 60 or more.
The performan ce of low- aspect- ratio tire s is par
ticularl y sensiti ve to imp roper inflat ion pres
sure . It is therefore import ant that low a spect
ratio tires are infl ated to the specified pressure
and that the inflation pre ssure is regularl y
checked and mainta ined . Tire pre ssure s shoul d
be checked at least once a month and alwa ys
befor e a long t rip
¢ page 215.
What you can do to avoid tire and rim
damag e
Low aspect rat io tires can be damaged more easi
ly by impact with potho les, curbs, gull ies or
Wh eel s
ridges on the road, particular ly if the tire is un
deri nflated.
In orde r to min imi ze the occurrence of imp act
damage to the tires of yo ur vehicle , we recom
mend that you observe the following preca u
tions:
- Always ma intain recommended inflat io n pres
sures. Check yo ur ti re pressure every 2,000
miles (3,000 km) and add air if necessary .
- Dr ive ca refully on roads w ith po tholes, deep
gullies or ridges . The impac t from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immediate ly inspect your
tires or have th em inspected by th e nearest au
thorized Audi dealer. Replace a damaged tire as
soon as possible.
- Inspect you r tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see . Damage can lead to loss of air and
underinflation, wh ic h could eventually cause
tire fa ilure. If you believe that a tire may have
been damaged , replace the tire as soon as pos
sib le.
- These tires may wear more quickly than others .
- Please also remember that, while these tires
delive r responsive ha ndling, they may ride less
comfortably a nd make more noise than other
choi ces.
Reduced perfo rmance in winter /cold se ason
conditions
All tires are des igned for certai n purposes. The
low aspect ratio, ultra high performance tires
o rigi na lly installed o n your veh icle are intended
f or maximum dry and wet road per formance and
handling . They are not suitable for co ld, snowy or
icy weather conditions . If you drive under those
c ircumstances, you should equip your vehicle
with all-season or winter tires, which offer better
tract ion under those condi tions. We suggest you
use the recommended snow or all-season tires
spec ified for your veh icle, or their equiva lent .

Maintenance
General '
Your vehicle has been designed to help keep
maintenance requirements to a minimum. How
ever, a certain amount of regular maintenance is
still necessary to assure your vehicle's safety,
economy and reliability . For detailed vehicle
maintenance consult your Warranty & Mainte
nance booklet .
Under difficult operating conditions, for exam
ple at extremely low outside temperatures, in
very dusty regions, when towing a trailer very fre
quently, etc., some service work should be per
formed between the intervals specified. This ap
plies particularly to:
- oil changes, and
- cleaning or replac ing the a ir filter .
'
@) For the sake of the environment
By regularly maintain ing your vehicle, you
help make sure that em iss ion standards are
maintained, thus minimizing adverse effects
on the environment .

scope of maintenance and repairs which can be
carried out by vehicle owners.
Also, safety and
environmental
concerns place very strict limits
on the nature of repairs and adjustments to en
gine and transmission parts which an owner can perform .
Maintenance, adjustments and repairs usually re
quire special tools, testing devices and other
equipment available to specially trained work
shop personnel in order to assure proper per
formance, reliability and safety of the vehicle and its many systems.
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of servicing in accordance with
the maintenance schedule may be a condition for upholding a possible warranty claim made within
the warranty period.
Above all , operational safety can be adversely af
fected, creating unnecessary risks for you and
your passengers.
If in doubt about any servicing, have it done by
your authorized Audi dealer or any properly equipped and qualified workshop. We strongly urge you to give your authorized Audi dealer the
opportunity to perform all scheduled mainte nance and necessary repairs. Your dealer has the
facilities, original parts and trained specialists to keep your vehicle running properly .
Performing limited maintenance yourself
The following pages describe a limited number of
procedures which can be performed on your vehi
cle with ordinary tools, should the need arise and
trained personnel be unavailable. Before per
forming any of these procedures, always thor
oughly read all of the applicab le text and careful
ly follow the instructions given . Always rigorously
observe the
WARNINGS provided .
Before you check anything in the engine com
partment, always read and heed all WARNINGS

- The engine compartment of any motor vehi
cle is a potentially hazardous area. Never
reach into the area around or touch the radi
ator fan. It is temperature controlled and
can switch on suddenly - even when the en
gine is off and the ignition key has been re
moved. The radiator fan switches on auto
matically when the coolant reaches a certain
temperature and will continue to run until
the coolant temperature drops.
- Always remove the ignition key before any
one gets under the vehicle.
-Always support your vehicle with safety
stands if it is necessary to work underneath
the vehicle . The jack supplied with the vehi
cle is not adequate for this purpose and
