@) For the sake of the environment
- Under no circumstances can the oil come
in contact with the sewage network o r
the soil.
- Observe and follow lega l regu lations
when disposing of empty oil containers .
Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv­
ice station.
Before you check anything in the engine com­
partment,
a lw ays rea d an d h eed all WARN­
INGS c::> .& in Working in the engine compart­
ment on page 214.
The engine oil must be changed accord ing to
the intervals specified in your Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di­
minish gradua lly during normal vehicle use .
Under some ci rcumstances the engine oi l
should be changed more frequently. Change
oil more often if you drive most ly short dis­
tances, operate the vehicle in dusty areas or under predominantly stop-and-go traffic con­
ditions, or have your vehicle where tempera­
tures remain below freezing for extended pe ­
riods .
Detergent addit ives in the oil w ill make fresh
oil look dark after the engine has been run­ n ing for a short time. This is normal and is not
a reason to change the oil more often than recommended.
Because of the problem of proper disposal,
along w ith the special tools and necessary ex ­
pertise required , we strongly recommend that
you have your o il changed by an authorized
Audi de ale r or a qual ified servi ce station.
If you choo se to c hang e y our oi l y our self,
please note the followi ng important informa­
tion :
A WARNING
To reduce the risk of personal injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protect ion.
- To reduce the risk of burns from hot en- gine oil, let the engine cool down to the
touch.
- When removing the o il dra in plug with
your fingers, stay as far away as possible.
Always keep your forearm parallel to the
ground to help prevent hot oil from run­n ing down you r arm.
- Dra in the oil into a container designed
for this purpose, one large enough to
hold at least the total amount of oil in
your engine.
- Engine oil is poisonous. Keep it we ll out
of the rea ch of childre n.
- Continuous contact with used eng ine o il
is harmfu l to your sk in. Always protect
your skin by washing oil off tho roughly
with soap and wate r.
@ Note
Never mix oil additives with your engine
oi l. These additives can damage your en­
g ine and adversely affect you r A ud i Limit­
ed New Veh icle War ranty.
@ For the sake of the environment
- Before changing your oil, first make su re
you know where you can prope rly dispose
o f the used oil.
- Always dispose of used eng ine oi l proper­
ly. Do not dump it on garden soil, wood­
ed areas, into open streams or down
sewage drains.
- Recycle used engi ne oil by taking it to a
used engine oil collection facility in you r
area, or contact a service station.

@ For the sake of the environment
Because of the pr oblem of proper d isposa l
of brake flu id as we ll as the special tools
requ ired and the necessary expert ise, we
recommend that you have the brake fluid
changed by your author ized Audi dealer .
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by an authorized
Aud i dealer or qualified workshop . The elec­
trolyte leve l should also be checked each time
the battery is charged ¢
page 22 7.
H ave the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a battery that is older than 5 yea rs .
W ith certa in types of a irbag deployment, t he
b attery is d isconnected from the vehicle elec­
tr ica l system for safety reasons¢.&.
in Re ­
pair, care and disposal of the airbags on
page 159.
Disconnecting the battery terminals
Some vehicle functions (power w indow regu­
lators , for example) are lost if the battery ter­
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
connected agai n. T o prevent this , the bat tery
should only be d isconnec ted from the vehicle
e lec tric al system when absolu tely necessa ry
for repairs .
Vehicles not driven for long periods
If you do not drive you r vehicle over a period
of severa l days or weeks, elec trical compo­
nen ts are gr adually cut b ack o r swi tched off .

turn o n the ign ition and start the engine.
Winter operation
D ur ing the w inte r mon ths, bat tery capa city
tends to dec rease as tempera tures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear window de­
fogge r, etc., are used more often.
Avoid unnecessary powe r consumpt ion, pa r­
ticular ly in city traffic or when traveling only
sho rt distances. Let yo ur authorized A udi
dealer check the capacity of the vehicle bat ­
tery before w inter sets in
¢ page 227. A well
charged battery will no t on ly prevent star tin g
problems w hen the weather is cold, but w ill
also last longer .
@ Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery s hou ld be removed and
stored where it will not freeze . This will
p revent it from be ing damaged and having
to be repla ced .
Working on the battery
Be especially careful when working on or near
the bat tery.
The battery is located in the luggage compar t­
ment under the floor . B efo re you che ck any­
thi ng in the luggage compartment,
read and
heed all WARNINGS

238 Tire s and whee ls
- Adjust the tire pressure to the load you are
carrying.
- Reinsta ll the va lve stem cap on the valve .
When should I ch eck the tire pres sur e?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and a lways before starting a journey. Do not
forget to check the tire pressure for the spare
wheel.
When should I adj ust the tire p re ss ures?
Adjust the tire pressure to the load you are
carry ing . After changing a wheel
o r replacing
wheels you have to adjust the tire pressures
on all wheels . In addition, you must then initi­
alize the new tire pressures in the tire pres­
sure monitoring system*~
page 249.
A WARNING
Incorrect tire pressures and/or underinf la­
tion can lead sudden tire failure, loss of
control, collision, ser ious personal injury
or even death.
- When the
RI] warning symbol appears in
the instrument cluster, stop and inspect
the tires .
- Incorrect tire pressure and/or underinfla­
t ion can cause increased t ire wear and
can affect the handling of the veh icle and
stopp ing ability.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
t ire pressures fo r all tires on the vehicle .
T he applicable p ressure va lues are locat­
ed on a sticker on the driver's side B-pil ­
lar.
- Only when a ll ti res on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring system* can work cor­
rect ly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified t
ire pressure values
for the tires and the correct pressures for
the function of the ti re pressure monitor­ing system*.
- Always inflate tires to the recommended
and correct t ire pressure before dr iv ing
off.
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire failure
and loss of cont rol.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have
to change a wh eel immediately, drive at
reduced speed to the nearest service sta­
tion to check the t ire p ressure and add
air as required.
Q) Note
D riving without valve stem caps can cause
damage to the tire valves. To prevent this,
a lways make sure tha t factory insta lled
valve stem caps on all whee ls are sec urely
mounted on the valve.
@ For the sake of the environment
U nderinflated tires w ill also incre ase the
fuel consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any tire can carry.
A vehicle that is over loaded will not handle
well and is more d iff icult to stop. Overloading
can not only lead to loss of vehicle control,
but can also damage important parts of the
vehicle and can lead to sudden tire fa ilure, in­
clud ing a b lowout and sudden deflation tha t
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are .,..

2. Determine the combined
weight of the driver and pas­ sengers that will be riding in
your vehicle.
3. Subtract the combined
weight of the driver and pas­ sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
¢ page 234, fig. 189.
4. The resulting figure equals
the available amount of car­
go and luggage load capaci­
ty. For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five 150
lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­
pacity is 650 lbs. (1400-750
(5
X 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle .
That weight may not safely exceed the available cargo
and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing
a trailer, load from your trail­
er will be transferred to your vehicle
. Consult this manual
to determine how this re­ duces the available cargo
and luggage load capacity of
your vehicle .
... check the tire sidewall
(¢ page 242, fig. 193) to de­
termine the designated load rating for a specific tire.
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.
Fig. 191 T ire tread: tread wear ind icato rs (TWI)

Fig. 192 Rotating tires for more even wear
Tread Wear Indicator (TWI)
The original tires on you r vehicle have
1/16 inch (1.6 mm) high "wear indicators"
cf> fig. 191 running across the tread. Depend-
ing on the make, there will be six to eight of
them evenly placed around the tire. Marks on
the tire sidewall (for example "TWI" or other ..,.

symbols) indicate the positions of the tread
wear indicators. Worn tires must be replaced.
Different fig ures may apply in other co untries
c:> .&. .
Tir e pres sure
Incorrect tire pressure causes premature wear
and can cause sudden tire blow -out. For this
reason, tire pressure must be checked at least
once a month
<=:> page 237.
Driving sty le
Driving fast around curves , heavy acceleration
and hard braking increase tire wear .
Rotating tires for mo re even wear
For all four t ires on your vehicle to have the
same se rvice life, we recommend that the
fro nt and rea r tires are rotated according to
the t ire manufacture r's suggested tire rota­
tion intervals. Please remember the follow ­
ing:
- T ire rotat ion inte rva ls may differ from the
vehicle service intervals outlined in your
Maintenance and Wa rranty Booklet .
- T he longer one tire is used in one location
on the vehicle, the more it wears at certa in
points; therefore, we recommend that you
fo llow the t ire manufacturer's suggested
t ire rotation intervals .
- Vehicles with front -wheel drive experience
more tread wear on the front wheels com­
pared to all whee l drive (quattro).
- Please rotate tires as shown
<=:> fig. 192.
-Extra care must be taken when rotating di-
rection-specific tires
c:> page 259 .
Wheel balancing
The wheels on new vehicles are balanced .
H oweve r, va rio us situations d uring eve ryday
driving can cause them to be come unbal­
anced, resu lting in vibrations you can us ually
feel through the steering wheel.
Unba lanced whee ls must be rebalanced to
avoid excessive wea r on s teer ing , suspens ion
and tires. A wheel must a lso be rebalanced
when a new tire is installed.
Tire s an d wheel s 241
Incorrect wh eel alignment
Incor rect wheel alignment can cause exces­
sive tire wear, impairing the sa fety of the vehi ­
cle . If tires show excessive wear, have the
whee l alignment checked by an authorized
Audi dealer or qualified workshop.
All wheel drive
Vehicles wi th quattro must always have tires
of the same size, construction and tread type.
For details see
<=:> page 192.
_8 WARNING
Sudden tire fa ilure can lead to loss o f con­
trol, a crash and serio us personal in jury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn ti res are a safety hazard, they do
not grip well on wet roads and increase
your r isk of "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, o il, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail sudden ly, especially at high
speeds. T ires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at lower
speeds.
- Never mount used tires on your veh icle if
you are not sure of thei r "previo us histo­
ry ." O ld used tires may have been dam­
aged even thoug h the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control. •
