Under certain circumstances, weekly washing may be necessary .
Under other conditions, a monthly washing and waxing may be
adequate.
After the winter, the underside of the vehicle shou ld be thoroughly
washed, p referably in a profess ional car wash.
& WARNING
Always read and heed all WARNINGS and other information
~page 256. •
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
Th e vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash . However, the
effect on the paint depends to a lar ge exten t on the design of the
facility, the filtering of the wash water, the type of wash and care material, etc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash.
Before going thro ugh a car wash, be sure to take the usual precau­
tions such as closing the windows and the roof. Factory installed
antennas must not be removed.
If you have installed additional accessories on the vehicle -such as
spoilers, roof rack, etc. - it is best to ask the car wash operator if these
should be removed.
& WARNING
Always read and heed all WARNINGS and other information

Appli es to veh icl es: wit h nat ura l leather
Natural leather
A udi makes gre at e ffo rts t o m ain tain the prop ert ies,
n a tu ra l loo k and fee l of inte rio r leat her .
General
We offe r many differen t types o f leat he r on our vehi cles. Most are
different types of nappa leather, wh ich has a smooth s urface and
comes in va rious co lo rs . _,,,

____________________________________________ C_l_e _a_ n_ i n--= g,___ a_n_ d----' p,___ r_o _t_ e_ c_ t_ i _o_ n __ _
The intensity of the color determines the visual characteristics and
appea rance. If the s urface of the leather has a typical natu ral look,
then the leather is a nappa leather that has been left in a relatively
natura l condition. This leather offers partic ularly good comfort and
breathes well. Fine veins, closed grains, insect b ites, sk in folds, and
subtle var iations in co lor remain visible. These character istics demon­
st rate that the mater ia l is nat ura l.
Natural nap pa leather is not covered by a color fin ish. It is therefore
mo re sensitive to soiling and we ar, which is some thi ng you need to
consider if children, animals or other factors mig ht prove to be partic­
ularly hard on the leather.
By contrast, leather types that a re cove red by a colo red fi nish layer
are more durab le . This has a positive effect on the leather's resistance
to wear and so ilin g in daily use. On the othe r hand, the typical charac­
teristics of natura l leather are barely or not apparent . However, this
does not mean that the leathe r itse lf is of inferio r quali ty.
Care and handling
Be cause of the exclusive na ture of t he types of leat her t ha t Audi uses
and their unique properties (such as sensitivity to oils, grease, soiling,
e tc. ), yo u will need to be somewhat c arefu l with these leat hers , a nd
a certain type of care is requ ired. For example, dark clothing mate­
r ia ls can dis co lor leather seats (especially if s uch cloth ing is damp and
was not dyed correctly). Dust and dirt particles in pores, folds, and
seams can have an ab rasive effect and can damage the leathe r
surface as well as weaken seams.
T he leather s ho ul d be cleaned regularly as needed . After having been
used for a relatively long time, your leather seats will a cquire a rich
aged f in ish. This is a characterist ic of natura l leather and a s ign of
t rue quality.
In order to maintain the value of this natural product over the life of
yo ur vehicle, you sho uld fo llow the recommendations below :
Safety first
0 Note
• To keep you r leat he r from b leach ing out, do not a llow it to be
exposed to bright s unlight for long periods of time . If yo u have to
leave t he veh icle parked o utside for long pe riods, cover the leather to
protect it from direct exposure to sunlight.
• Sharp objects on clot hing, such as z ippers, rivets or sha rp pieces
on belts can leave permanent scratches or scrape mar ks on the
surfa ce of the leathe r.
(I] Tips
• After ea ch t ime you clean the le athe r and at regular inte rvals, use
a leather preservat ive cream that contains UV-blockers and that
works into the leather . This cream will nourish and moistu rize the
leather, helping it to breathe and stay supp le. It also he lps to build up
a protect ive coa ting on the surface .
• Clean the leather every 2 -3 months, and clean any areas t hat get
so ile d.
• Remove fresh marks made by ballpoint pens, ink, lipstick, shoe
polish, etc. as soon as poss ible.
• Preserve the color of the leather as needed by using a special
c o lored leat he r car e cream to touch up a reas of uneven color. •

0 Note
• Before w inter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if yo u live in a region where
the winter is extremely cold.
If necessary, increase the proportion of
coolant additive to 60% .
• When adding coolant additive to your cooling system, remember :
- We recommend using only coolant additive G12++ (check the
label) for your vehicle. This coolant additive is available at autho­
r iz ed Audi dealers. Other types of antifreeze can s ignificantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle 's
engine coolant. Adding radiator repair flu id may adversely affect the
function and performance of your cooling system and cou ld result in
damage not covered by your New Vehicle Limited Warranty .•
Checking the engine coolant Level
The engine coolant level can be checked with a quick
glance.
Fig. 208 Engine
co mpartment : Coolant
expansion tank
Before you check anything in the engine compartment,
always read and heed all WARNINGS~ & in "Working in
the engine compartment" on
page 275.
-Turn off the ignition.
- Read the engine coolant level from the coolant expansion
tank~ fig. 208 . With a cold engine, the coolant level
should be between the "MIN" and "MAX" markings. When
the engine is warm, the level may be slightly above the
"MAX" marking.
The locat io n of the coolant expansion tank can be seen in the engine
compartment illustration~
page 276.
To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehicle is equipped with an electric coolant level sensor.
When the coolant level is too low, the warning light in the Auto-Check
System =>
page 34 will blink until you add coolant and the level has
been resto red to normal. Even though there is an electric coolant
level sensor, we still recommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the coo ling system. In the event of
coolant loss, the cooling system should be inspected immediately by
your authorized Audi dealer. It is not enough merely to add coolant.
In a
sealed system, losses can occur only if the boiling point of the
coo lant is exceeded as a result of overheating .
& WARNING
The cooling system is under pressure and can get very hot. Reduce
the risk of scalding from hot coolant by following these steps.
• Turn off the engine and allow it to cool down.

___________________________________________ C_ h_e _c _k_ i_n ~g_ a_n_ d_ f_ i_ll _i_n _g __ _
The fluid level may drop slightly after some time due to the auto­
matic adjustment of the brake pads. This is not cause for alarm.
If the brake flu id level falls considerably below the "MIN " mark, the
brake warning/indicator light (U.S. models:
BRAKE , Canadian mode ls:
{(j)) ) will come on=> page 18 and=> page 33. Do not continue to
ope rate the vehicle. The complete brake system should be thorough ly
checked by an authorized Audi dealer or qualified workshop and the
cause corrected. If the brake fluid level is too low, the brake
wa rning/ind icator light will illuminate. Contact an authorized Aud i
dealer
immediately .
[I] Tips
The brake fluid reservoir is located undernea th the cover. •
Changing brake fluid
Hove the broke fluid changed by on experienced techni­
Clon.
Brake fluid absorbs moisture from the air. If the water content in the
brake fl uid is too high, corrosion in the brake system may result after
a period of time. The boiling point of the brake fluid will also decrease
considerably and decrease braking performance.
Therefore, the brake flu id must be changed
every two years. Always
use new brake fluid which conforms to Federal Motor Vehicle Stan­
dard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to reach, therefore, we
recommend that you have the brake fluid changed by your authorized
Audi dealer. Your dealer has the correct tools, the right brake fluid
and the know-how to do this for you .
& WARNING
• Brake fluid is poi sonous. It must be stored only in the closed
original container out of the reach of children!
Safety first
& WARNING (continued )
• Brake failure can result from old or inappropriate brake fluid.
Observe these precautions:
-Use only brake fluid that meets SAE specification
J 1703 and
conforms to Federal Motor Vehicle Standard 116. Always check
with your authorized Audi dealer to make sure you are using
the correct brake fluid . The correct type of brake fluid is also
indicated on the brake fluid reservoir.
- The brake fluid must be new. Heavy use of the brakes can
cause a vapor lock if the brake fluid is left in the system too
long. This can seriously affect the efficiency of the brakes as
well as your safety. This could result in an accident .
0 Note
Brake fluid will damage the paint of your vehicle.
ffi For the sake of the environment
Because of the prob lem of proper disposal of brake fluid as well as
th e special tools required and the necessary expertise, we recom­
mend that you have the brake fluid changed by your author ized Audi
dealer. •
Battery
General information
Under normal operating conditions, the battery in your Audi does not
need any maintenance . With high outside temperatures or long daily
drives we recommend that you have the electro lyte level checked by
an authorized Audi dealer or qualified workshop . The electrolyte leve l
should also be checked each t ime the battery is charged=> page 288.

Tires
General notes
Tires may be the least appreciated and most abused
parts of a motor vehicle.
T ir es may be the least appreciated and most abused pa rts of a motor
vehicle . Tires are, however, one of the most important parts of a
vehicle , pa rticul arly conside ring the comparat ive ly small patch of
rubber on eac h tire that assures that all-important contact between
you, your veh icle and the road.
Maintai ning t he cor rect tire pressu re, mak ing su re that your veh icle
and i ts tires do not have to carry more weight t han they can safely
hand le, avoid ing damage from road ha za rds and regularly inspecting
tires for damage includ ing cuts, s lashes irregular wea r and ove rall
condi tion a re the mos t important th ings that you can do to help avoid
sudden t ire failure including tread separation and blowouts.
Avoiding damage
If you have to d rive ove r a cur b or sim ilar obstacle, d rive very slowly
and as close as possible at a rig ht angle to the curb .
Always keep chemicals incl ud ing grease, oil, gaso line and brake f luid
o ff t he t ires .
Ins pect the ti res regularly for damage (cu ts, cracks o r blisters, e tc.) .
Remove any foreign bodies embe dded in the treads.
Storing tires
M ark tires w hen yo u remove t hem to indica te t he d ire ct io n of rota ­
tion . This ensures you to be ab le to mount them correctly when you
re insta ll them.
Whe n removed, t he wheels or tires should be sto red in a cool, dry and
preferably da rk p lace.
Safety first
Store tires in a v ertica l pos it io n if they a re not mount ed on rims, in a
hor izonta l posit ion if they are mounted on r ims.
New tires
N ew tires have to be broken in~ & .
Th e tre ad d epth of new ti res may v ary, accor ding t o th e type an d

Hidden damage
Damage to tires and rims is often not readi ly visible. If yo u notice
unu sual vib ra ti on o r the ve hicle pulls to one side, t his may in dica te
that one of the t ires has been damaged. The tires must be checked
im media tely by an auth oriz ed A ud i d eale r or qual ifie d wor ks hop.
Unidirectional tires
A un id irectional tire can be identified by arrows o n th e sidewall , th at

Tire pressure
Incorrect tire pressure causes premature wea r a nd can cause sudden
t ire blow-out. For this reason, ti re p ressure must be checked at least
once a month ~
page 297.
Driving style
Driving fast around curves, heavy acce le ra tion and hard brak ing
increase tire wear .
Rotating tires for more even wear
For all four tires on your veh icle to have the same service life, we
re commend that the fron t and re a r tires are rotate d according to the
tire manufact urer's suggested tire rotation interva ls . Please
remember the fo llow ing:
• Tir e rotat ion inte rvals may differ from t he ve hicl e service intervals
outlined in your Maintenance and War ranty Booklet .
• T he longer one tire is used in one location on the veh icle, the more
it wears at certa in points; therefore, we recommend that you follow
t he t ire m anufac ture r's suggested tire rotation in terva ls.
• V ehicles with front-whee l drive expe rience mo re tread wea r on t he
fron t wheels compa red to all-whee l drive (quattro
® ).
• Please rotate tires as s hown ~fig. 215.
• Extra care must be taken when rotating d irection-specific tires
~ page 321.
Wheel balancing
The w heels on new vehicles are balanced. Howeve r, va rious sit uat io ns
dur ing eve ryday dr iv ing can cause them to become unbalanced,
re su lt ing in v ibr ations yo u can usually fee l throug h the steering
wheel.
Unbalanced wheels must be rebalanced to avoid excessive wea r on
steeri ng, suspension and t ires . A wheel must also be rebalanced
w hen a new tire is installed.
Incorrect wheel alignment
Incorrec t whee l alignment can ca use excessive tire wear, impai ring
t he sa fety of the veh icle . If tires show excess ive wear, have the wheel
alignment checked by an authorized A udi dealer or qualified wo rk­
shop .
All wheel drive
Vehicles w ith q uattro ® must always have ti res of the same size,
const ructio n and trea d type. For details see~
page 242 .
& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wea r ind icato rs.
• Worn tire s are a safety hazard, they do not grip well on wet
roads and in crease your risk of "hydroplaning" and lo ss of control.
• Always keep chemicals that can cause tire damage, such as
grease , oil , gasoline and brake fluid away from tires.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tire s on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •
