@ For the sake of the environment
Be cause of the problem of proper disposa l
of brake flu id as we ll as the special tools
req uired and the necessary expert ise, we
recommend that you have the b rake fluid
changed by your author ized Audi dealer.
Battery
General information
Unde r normal operating conditions, the bat
tery in your A udi does not need any mainte
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the elect ro lyte level checked by an authorized
Aud i dea ler o r qualified workshop . The elec
trolyte leve l sho uld a lso be c hecked each t ime
the battery is c harged ¢
page 244.
Have the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a bat tery that is older tha n 5 yea rs .
W ith certa in types of a irbag deployment, t he
battery is d isconnected from the vehicle elec
tr ica l system fo r safety reasons ¢

page 171.
Hybr id d rive *: you can find important i nforma
tion about the high voltage battery under
¢ page 97.
Disconnecting the battery terminals
Some veh icle functions (power w indow regu
lators, for example) are lost if the battery ter
minals a re discon nected. These functions have
to be re learned after the ba tte ry term inals a re
connect ed aga in. To prevent this , the battery
should only be d isconnected from the vehicle
e lec tric al sys te m whe n absolu tely necessa ry
for rep airs.
Vehicles not driven for long periods
If yo u do not dr ive you r vehicle over a pe riod
of severa l days or w eeks, ele ct rical com po
n e nt s are gr adually cu t ba ck o r swi tched off .

Take i nto consi deratio n that whe n you unl ock
yo ur vehicle, some conven ien ce f un ctions ,
s u ch as the inte rior ligh ts or the powe r sea t
adjustment, may not be availab le. T he con
venience functions will be avai lab le aga in
when you tu rn on the ign ition and start t he
engine.
Winter operation
Du ring the winte r mon ths, bat tery ca pac ity
tends to dec rease as tem peratures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear wi ndow de
fogger, etc ., are used more often.
Avoid unnecessary powe r consum ption, pa r
t icu lar ly in city traffic or when traveling only
sho rt distances. Let your authori zed Aud i
dealer check the capacity of the vehicle bat
te ry before winter sets in ¢
page 244. A well
c h arged battery will not on ly preven t starti ng
problems when the wea ther is cold, but w ill
also last lo nger.
Working on the battery
Be especially careful when working on or near
the ba ttery.
The battery is located in the luggage compart
me nt under the floor . B efo re you c hec k any
t hi ng in the luggage compartmen t,
read and
heed all WARNINGS

Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correc t tire pressure and driv
ing style .

Tread Wear Indicator (TWI)
The o rigina l tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c::;, fig. 207 running across the tread . Depend
ing on the make, there will be six to eight of
them evenly p laced around the t ire. Marks on
the t ire s idewa ll (for example " TWI" or other
symbols) indicate the positions of the tread
wear ind icators. Wo rn t ires must be r ep laced .
Tires and wheels 25 7
Different figures may app ly in other countries
c::;, .&. .
Tire pressure
Incor rect tire press ure ca uses premature wear
and can c ause sudden tire blow-out. For this
reason , tire pressure m ust be checked at least
once a month
c::;, page 2 53.
Driving style
Driving fast around curves, h eavy acce le rat ion
and har d bra king increase tire wear .
Rotating tires for more even wear
For all four tires on your ve hicle to have the
same service life, we recommend that the
front and rear t ires a re rotated according to
the tire manufact urer's suggested tire ro ta
tion intervals. Please remembe r the follow
ing:
- Tire rotation intervals may differ from the
veh icle service inte rva ls o utlined in your
Ma intenance and Warranty Boo klet .
- The longer one tire is used in one location
on the vehi cle, the more it wears at cer tain
points ; the refore, we recommend that you
follow t he tire manu fact urer's suggested
tire rotation intervals .
- Ve hicl es w ith front-wheel dr ive exper ience
more tread wear on the front w heels com
pared to a ll-wheel drive (quattro) .
- Please rot ate tires as shown
c::;, fig . 208.
- Extra care mus t be taken whe n rota ting di-
rection-spec ific tires
c::;, page 277 .
Wheel balancing
The wheels on new veh icles are balanced .
However, various s ituations during eve ryday
driv ing ca n cause them to become unba l
anced, re su lting in vib rat io ns you ca n usually
feel t hrough the s teer ing whee l.
Unbalanced wheels must be rebalanced to
avo id excessive wear on steering, s uspension
and t ires. A whee l m ust also be reba la n ced
whe n a new tire is insta lled.
