Winter tires
Winter tires significantly improve the vehicle 's
handling when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern), summer tires provide less 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
9 .&, in
General information on page 244.
An author­
ized Audi dea ler or authorized Audi Service Fa­
cility can inform you about the maximum per­
mitt ed sp eed for your tires .
.. Check the tire pressure after installing wheels
9page 254.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .1S7 in (4 mm) . The chara cteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread .
@.l For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
w inter tires . Please note that in some coun­
tries where w inter tire s are required, only
w int er tires with
the£ symbol may be per­
mitted.
Snow chains
Snow chains not only improve the driving in win­
ter road conditions, but also the braking.
Wheels
.. Only install snow chains on the front wheels.
This applies a lso to vehicles with all wheel
drive* .
.. Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer .
.. Note the maximum speed of 30 mph (SO km/
h) . Note the local regulations .
Use of snow chains is only permitted with certa in
rim/tire comb inat 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 .
You must remove the snow chains on roads with­
out snow . Otherwise, you could impair driving
ability and damage the tires .
.8, WARNING
Using incorrect snow chains or install ing snow
chains inc orrectly can resu lt in loss of veh icle
control, which increases the risk of an acci­
dent.
(W) Note
- Snow chains can damage the rims/wheel
covers* if the chains come into direct con­
tact with them. Remove the wheel covers*
first. Use coated snow chains.
- Using snow chains that add more than O.S3
in (13,S mm) of height can severe ly damage
the whee l housings and other vehicle com ­
ponents .
(D Tips
When using snow chains, it may be usefu l to
switch on sport mode
~ page 87.
Low-profile tires
App lies to: vehicles wi th low- pro fil e tir es
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls .
This results in an ag ile driving style . However, it
may reduce the level of comfort and increase
r oad noise when driving on roads in poor condi-
tion.

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, etc., some service work shou ld be performed between the intervals speci ­
fied. This applies particularly to:
- oil changes , and
- cleaning or replac ing the a ir filter .
@) For the sake of the environment
By regularly maintaining your vehicle, you
help make sure that em iss ion standards are
maintained, thus min imizing adverse effects
on the environment .
Important considerations for you and your
vehicle
The increasing use of electronics, soph isticated
fuel injection and emission control systems, and
the genera lly increasing technica l complexity of
today's automobiles, have steadily reduced the

scope of maintenance and repairs which can be
carried out by vehicle owners.
Al so, sa fety a nd
en vir onment al
concerns place very strict limits
on the nature of repairs and adjustments to en­
g ine and transm ission parts wh ich an owner can
perform .
Maintenance, adjustments and repairs usually re­
qu ire special tools, test ing devices and other
equ ipment available to specially trained work­
shop personnel in order to assure proper per ­
formance, rel iability and safety of the veh icle and
its many systems .
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
veh icle and even void your vehicle warranty .
Therefore, proof of servicing in accordance with
the ma intenance sc hedule may be a condition for
upho ld ing a possib le wa rranty claim made within
the warranty period.
Above all, operational safety can be adversely af­
fected, creating unnecessa ry risks fo r you and
your passenger.
If i n doubt about any servicing, have it done by
your author ized Audi dealer or any other properly
equ ipped and qua lified workshop. We strongly
urge yo u to g ive your author ized Audi dealer the
opportunity to perform a ll scheduled ma inte­
nance and necessary repairs. Your dealer has the
facilities, origina l parts and trained specialists to
keep your vehicle running properly .

A WARNING
--
- Ser ious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs .
- Always be extremely careful when work ing
on the vehicle . Always follow commonly ac­
cepted safety practices and general com­ mon sense. Never risk pe rsonal inj ury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fu lly famil iar with these
or other proced ures with respect to the ve­
h icle, or are uncerta in how to pro ceed.
- Do not do any work without the proper tools
and eq uipment. Have the necessary wo rk
done by your authorized Audi dealer or an­
other proper ly equipped and qualified work­
shop.
- 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
g ine is off . The radiator fan switches on au­
tomatically when the coolant reaches a cer­
tain tempe rature and will cont inue to run
until the coolant temperature d rops.
- Always sw itch off the ignition before anyone
gets under the vehicle.
- Always support your veh icle with safety
stands if it is necessary to work underneath
the vehicle. The jack suppl ied with the veh i­
cle is no t adequate for this pu rpose and
could collapse caus ing serious personal in­
jury.
- I f you must wor k unde rneath the vehicle
with the wheels on the ground, always make
sure the vehicle is on level ground, that the
wheels are always securely blocked and that
the engine cannot be started.
- Always make sure the transmission se lector
lever (automatic transmiss ion) is in P (Park
position) and the park brake is applied.

Technical Modifications
Our guidelines must be complied with when tech­
nical modifications are made .
Always consult an authorized Audi dealer before
starting work on any mod ificat ions.
This will help ensure that vehicle function, per­
formance and safety are not impaired
c> ,&.
Attempting to work on e lectronic components
and the software used with them can cause mal­
functions. Because of the way electronic compo­ nents are interconnected with each other, such
malfunct ions can also have an adverse effect on
other systems that are not directly involved. This
means that you risk both a substantial reduct ion
in the operational safety of your veh icle and an
in creased wea r of ve hicle pa rts

Author ized Audi dealers w ill perform this work in
a profess ional and competent manner or, in spe ­
cial cases, refer you to a professional company
that spec ializes in such modifications.
.&_ WARNING
Improper repairs and modifications can
change the way vehicle systems work and
cause damage to the vehicle and serious per­
sonal injury.
{Q) Note
If emergency repa irs must be performed else ­
where, have the vehicle examined by an au­
t horized A udi dealer as soon as possible.
