Fa ults in the brake system
If yo u should notice a sudden increase i n brake
pedal travel, then one of the two brake circuits
may have failed
¢ .&. .
Low brake fluid level
Malf unct ions can occur in the bra ke system if the
b rake fl uid leve l is too low. The brake fluid level
i s monitored e lectronica lly .
Bra ke booste r
The brake booster increases the pressure that
you generate with the brake pedal.
It works on ly
when the engine is run ning
.¢ .&.
Bra ke lining we ar status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the open ings in the wheel. If necessary,
the wheel may be removed for this inspection
¢ page 228, Replacing wheels.
A WARNING
- New bra ke pads don't have the best stop­
ping power and must be "bro ken- in" dur ing
the init ia l 250 m iles (400 kilometers). Yo u
can compensate for th is by press ing the
brake pedal more firmly. This a lso applies
later when new pads are installed.
- Yo u should perfo rm braking maneuvers for
the p urpose of clean ing the brake system
only if road conditions permit. Other road
users must not be put at risk -you may
cause an accident!
- Before descending a steep grade, reduce
speed and shift t ransm iss ion into a lower
gear or lowe r driving range. Do not ride the
brakes or hold the pedal down too long or
too often. This could ca use the brakes to get
hot and diminish brak ing efficie ncy.
- Do not "r ide t he b rakes" by resting your foot
on the pe dal when yo u do not inten d to
bra ke. This may cause the bra kes to over­
heat, premat ure wear and increased stop ­
ping distance.
- Under certa in climatic and operating condi­
tio ns such as passing thro ugh water, driving
in heavy rain or after washing the vehicle,
Intellig ent Technology
the effectiveness o f the brakes can be re­
duced. In winter, ice can accum ulate on the
brake pads, lin ings, d iscs and drums . Care­
fu lly apply brakes for a test . Brakes will dry
and ice coat ings will be cleaned off after a
few ca refu l brake applications .
- Driving for an extended period of t ime on
salt-covered roads without usi ng your
b rakes can also affect braking eff iciency.
Clea n off acc umul ated salt coat ing from
b rake discs an d pa ds w ith a few careful
b rake appli cat ions .
- I f you d amage the front spoile r, or if you in­
s t all a different spoiler, be s ure the a ir flow
to the front brakes is not obstruc ted. Other­
wise the brake system could overheat reduc­ ing the effectiveness of t he ent ire bra ke sys­
tem.
- Fai lure of one brake circuit w ill impa ir the
braking capability resulting in an increased
stopping distance . Avoid driving the vehicle
and have it towed to the nearest authorized
Aud i dealer or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed cons iderab ly
ha rder to make up fo r the lack of booste r
assis tance .

Winter tires
When dr iving in the winter, yo ur vehicle with all­
whee l dr ive has a n advantage, even with regu la r
t ir es. In w inte r road cond it ions i t may be advisa­
ble to mo unt win ter tires (o r all-se ason tires) for
i mproved driveability an d braking: these ti res
must be mo unted on
all four whee ls. See also

Off-Road driving?
Your Aud i does not have enough g ro und clear­
ance to be used as an off -road vehicle. It is there ­
fore best to avoid roug h tracks and uneven ter­
rain as much as possible. A lso refer to
¢ page 175.
_&. WARNING
Always adjust you r driving to road and t raff ic
conditions. Do not let the extra safety afford­
ed by all-wheel drive tempt you into tak ing
extra risks.
-Although the all-whee l dr ive is very effec­
t ive, a lways remember that bra king capac ity
is limited by tire traction . Yo u should there­
fore not d rive a t exc ess ive speeds on icy or
slippery road su rfaces.
- On wet ro ad surfaces, be caref ul not to drive
too f ast be cause the fro nt wheels co uld be­
gin to slide on top of the w ater ( aquaplan ­
ing). If this sho uld o ccu r, you w ill have no
warning from a sud den increase in eng ine
speed as with a front-whee l dr ive vehicle .
Always drive at speeds wh ich are su ited to
the road cond it ions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa­
bility of electrical energy for s tarting the engine.
If a veh icle wit h a conventional energy system is
not driven for a long per iod of t ime, the battery is
d ischa rged by idling current consumers (e.g. im­
mo bilizer). In cert ain cir cums tan ces it c an result
i n there be ing insuff ic ient ene rgy available to
start the engine.
I ntell igen t energy management in your veh icle
h andles the distr ib ution of ele ct ric al ene rgy.
S tarting ab ility is mar ked ly imp roved an d the l ife
of the batte ry is extended.
B asically, e nergy management consis ts of
bat­
tery diagno sis, idling curr ent management
and
dynamic energy management .
Intelligent Technology
Battery diagnosis
Battery diagnos is con tinuously dete rmi nes the
state o f the bat tery . Sensors determine battery
vo ltage, battery c urrent and batte ry tempera­
tu re. This determines t he current state of charge
and the power of the battery.
Idling current management
Id ling cur rent management reduces ene rgy con­
s u mption whi le the vehicle is standing . With the
ignition switched off, it contro ls the energy sup­
ply to the vario us electrical components . Data
from battery d iagnosis is cons idered.
Depend ing on the ba ttery's s tate of charge, indi ­
vidual consumers are gradually turned off to pre­
vent excess ive discharge of t he battery and thus
mainta in starting capab ility.
Dynamic energy management
While t he vehi cle is being d riven, dynami c energy
management dis trib utes the energy generate d
according to the needs of the individual compo­
nents. It regulates consumption, so that more
electrical e nergy is not being used than is being
generated and ensures an opt imal state of
charge for the battery .
(i) Tips
-But even ene rgy management cannot neg­
ate the lim its of physics. Consider that the
powe r and life of a battery are lim ited.
- If starting ab ility is threatened, the indica ­
to r li ght (•) appears¢
page 14.
What you should know
The highest priority is given to maintaining start­
ing capability.
The battery is severe ly taxed in short-distance
driv ing, in city traffic and dur ing the cold time of
year. Abundant e lectrica l energy is required, but
o n ly a little is generated. It is also c ritical if the
engi ne is not running and electrical components
are tu rned on . In this instance energy is being
co nsumed bu t no ne is being ge nerated. .,,.

Backing up is difficult and requires practice.
Backing up with a trailer generally requires steer­
ing action oppos ite to that when backing up your
vehicle without a trailer.
Maintain a greater distance between your vehicle
and the one in front of you. You wi ll need more
room to stop. To compensate for the tra iler, you
will need a larger than normal turning radius.
When passing, remember that you cannot accel­
erate as fast as you normally would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
@ Tips
- Do not tow a trailer during the break-in peri­
od of your vehicle.
- If you tow a trailer, your Audi may require
more frequent maintenance due to the ex ­
tra load
~ page 246.
Parking on a slope
Do not pork on o slope with o trailer. If it cannot
be avoided, do so only ofter doing the following:
When parking:
" Apply the foot brake.
"Have someone place chocks under both the ve­
hicle and the trailer wheels.
" With chocks in place, slowly release the brakes
until the wheel chocks absorb the load.
" Turn the wheels towards the curb.
" Apply the parking brake.
" Move the selector lever to P .
When restarting after parking:
" Apply the foot brake.
" Start the engine .
" Move the selector lever to D/S.
" Release the parking brake and slowly pull out
and away from the wheel chocks.

wash operator to reduce the risk of acc idents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings .
- After washing the vehicle, the brak ing effect
may be delayed due to mo isture on the
brake rotors or ice in the w inter . This in­
c reases the risk of an acc ident. The bra kes
must be d ried fi rst w ith a few careful b rake
applications.
(D Note
- If you wash t he vehicle in an automatic car
wash, yo u m ust fold the exte rior m irrors in
to reduce the risk of damage. Power fo ld ing
exter ior mir ro rs* m ust only be folded in and
out using t he power folding fu nction .
- To reduce the risk of paint damage, do not
wash the vehicle in d irect sunlig ht.
- To reduce the risk of damage, do not wash
th e power top wit h a press ure washe r.
Ca re and cleaning
- To re duce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or s imilar items .
- Matte finish painted veh icle components:
- To reduce the risk of damage to the sur-
face, do not use po lishing agents or hard
wax.
- Never use protective wax . It can destroy
the matte finish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint . The paint cou ld be damaged
when the stickers or magnets are re­
moved .
@ For the sake of the environment
Only wash the vehicle in facili ties s pec ia lly de­
s igned for that pu rpose. This will reduce the
r isk of dir ty wate r contam ina ted with o il from
en te ring the sewe r sys tem.

General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.M ark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction

and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.
