Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new
brake pads do not possess their fu ll braking
effect, they have to be "broken in" first
c> .&. .
You can compensate for this slightly reduced
braking power by push ing harder on the brake pedal. Avoid heavy brak
ing loads dur ing the
break -in period.
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving hab its
c> .&. . On
vehicles that are either driven mostly in stop­ and-go city traff ic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often than specified in
the
Warranty & Maintenance booklet. Failure
to have you r brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
effect of the engine . This way, you prevent un ­
necessary wear on the brake system.
If you
must use your brakes, do not hold the brakes
down continuous ly . Pump the brakes at inter­
vals.
Operating noise
Noises may occur when braking depending on
the speed, b rak ing force and outside cond i­
t ions such as temperature and humidity .
Effect of water and road salt
In certain situations, for example after driv in g
t hr ough water, in heavy rain, after overnight
condensation or after washing you r car, the
braking effec t can be reduced by mois ture or
ice on the brake rotors and brake pads. The
brakes must be dried first with a few careful
brake applications .

At higher speeds and with the windshield wip ­
ers turned on, the brake pads press against
the brake rotors for a short amount of time.
This occurs at regular intervals without the
driver noticing and provides for better brake
response time under wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered
road and the brakes are not used . Likewise,
you clean
off accumulated sa lt coating from
brake discs and pads with a few cautious ap­
plications of the brake~&. .
Cor ro sion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for short trips with little use of the
brakes .
If the brakes are not used frequently, or if cor­
rosion has formed on the discs, it is advisable
to clean
off the pads and discs by brak ing
firm ly a few times from a moderately h igh
speed
¢ .Li). .
Fa ults in the brake system
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circu its may have failed~&,. .
Low brake flu id le vel
Malfunct ions can occur in the brake system if
the brake fluid level is too low . T he brake fluid
level is monitored electronically .
Brake boo ste r
The brake booster increases the pressure th at
you generate w ith the bra ke pedal. It works
only when the engine is running
. ¢ &.
Brake lining w ear statu s
Brake lining wea r may be c hecked by vis ual in­
spection of the condition of the brake pads
through the openings in the whee l. If neces ­
sary, the whee l may be removed for this in­
spection

A WARNING
-New brake pads don't have the best stop­
ping power and must be "b roken-in" dur­
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal c ity dr iving .
You can compensate for this by pressing the brake pedal more firmly. This also
applies la ter when new pads are instal­
led.
- You should perform braking m aneuvers
for the purpose of cleaning the brake
system only if road conditions permit .
Other road users must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gea r or lower dr iving range. Do not ride
the brakes or hold the pedal down too
long or too often . Th is could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing your
foot on the pedal when you do not intend
to b rake. This may cause the brakes to
overheat, p remature wear and increased
s topping distance.
- Unde r ce rtain cl imatic and ope rat ing
conditions such as passing thro ugh wa ­
ter, dr iv ing in heavy rain o r after washing
the vehicle, the effectiveness of the
brakes can be reduced. In winter, ice can
accumu late on the brake pads, linings,
discs and drums. Carefully app ly brakes
for a test. Brakes w ill dry and ice coat­
ings w ill be cleaned
off after a few care­
fu l brake applicat ions .
- Driving for an extended period of time o n
salt-cove red roads without using your
brakes can a lso affect braking efficiency.

- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­ est author ized Audi dealer or qualified
workshop .
- Never let the vehicle roll to a stop w ith
the engine shut off .
- If the brake booster is not working, the
brake pedal must be pressed conside ra ­
bly harder to make up for the lac k of

Driving with your
quattro
App lies to vehicles: wi th all-w hee l drive
With a/I-wheel drive , all four wheels are driv­
en .
General information
With a ll-wheel d rive, power is distr ib uted to
all four wheels. This happens automatically
depending on your driving style and the road
co ndit ions at the time . See also ¢ page 179 .
A center d ifferential distributes the driving
power variably to the front and rear axle. It

t ia l* , pow er d istr ibut ion to the rea r wheels is
variable a nd can be adjusted w ith drive se lect
Q page 106. .,..

The all-wheel drive concept is designed fo r
high engine power. Your vehicle is exception ­
ally powerful and has exce llent dr iving charac­
ter istics both under normal driving conditions
and on snow and ice . Always read and follow
safety precautions
c> & .
Winte r tires
When driving in the winter, your ve hicle with
all-wheel drive has an advantage, even with
regular t ires. In winter road conditions it may
be adv isable to mount winter tires (or all-sea­
son t ires) for imp roved driveability and brak­
i ng: these tires must be mounted on
a ll four
w heel s.
See also c> page 23 7, Winter tires.
Tire chain s
Where tire cha ins are mandatory on certain
roads, th is normally also applies to vehicles
with all-wheel drive
c> page 238, Snow
chains.
R eplacing wheel s/tire s
Vehicles with all-wheel drive must a lways
have tires of the same size. Also avoid t ires
with d ifferent tread depths . For details see
page ~
page 233, New tires and replacing
tires and wheels.
Off-Ro ad dri ving ?
Your Audi does not have enough ground clear­
ance to be used as an off-road veh icle. It is
therefore best to avoid rough tracks and un­
even terrain as much as possible . Also refer to
c> page 187.
A WARNING
Always adjust your driving to road and traf­
fic condit ions . Do not let the ext ra safety
afforded by all-wheel drive tempt you into
taking extra risks .
- Although the all-whee l dr ive is very ef­
fective, a lways remember that b raking
capacity is limited by tire traction. Yo u
sho uld therefore not drive at excessive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
dr ive too fast because the front wheels
Int ellig ent technolog y 185
could begin to slide on top of the water
(aquaplaning). If th is should occur, you
will have no warning from a sudden in­ crease in engine speed as w it h a front­
wheel drive veh icle . Always drive at
speeds which are su ited to the road con­
ditions - risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle with a conventiona l energy system
is not driven for a long period of time, the bat­
tery is discharged by idling current consumers (e .g. immobilizer). In certain circumstances it
can resu lt in there being insuffic ient energy
available to start the eng ine .
Intelligent energy management in your vehi­
cle handles the distribution of e lectr ica l ener­
gy. Start ing ability is markedly improved and
the life of the battery is extended .
Basically, energy management consists of
battery diagnosis , idling current manage­
ment
and dynamic ene rgy management .
Batte ry diagnos is
Battery diagnosis continuously determines
the state of the batte ry . Sensors determine
battery voltage, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumption while the vehicle is standing.
With the ign ition switched off, it controls the
energy supply to the various electrical compo­
nents. Data from battery d iagnos is is cons id­
ered .
Depend ing on the battery's state of charge,
individual consumers are gradually turned
off .,_ •

194 Trailer towing
Trailer towing tips
Important to know
Your vehicle hand les different ly w hen tow ing
a tr ailer because of the addit ional weight and
different weight distribution . Safety, perform­
ance and economy wi ll greatly depend on how
carefully you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turning, stopp ing and backing up in an area
away from traffic. Keep practicing until you have become comp letely familiar with the way
your veh icle-trailer combination behaves and
responds.
Backing up is difficult and requires practice.
Backing up with a trai ler genera lly requires
steering action opposite to that when backing
up your veh icle without a trailer.
Maintain a greater distance between your ve­
hicle and the one in front of you . You will need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius .
When passing, remember that you cannot ac­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your tra iler before chang­
in g lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
{Dl Tips
- Do not tow a tra iler dur ing the break-in
period of your vehicle.
- If you tow a trailer, your A udi may re­
quire more frequent maintenance due to
the extra load
q page 264.
Parking on a slope
Do not park on a slope with a trailer . If it can­
not be avoided, do so only after doing the fol­ lowing :
When parking:
.. App ly the foot brake.
.. Have someone place chocks under both the
veh icle and the trailer wheels .
.,. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load.
.. Turn the whee ls towards the curb.
.. App ly the parking brake.
.. Move the selector lever to P.
When restarting after parking:
.. App ly the foot brake .
.. Start the engine.
.. Move the selector lever to D/S .
.. Release the parking brake and s lowly pull
out and away from the wheel chocks .
.. Stop and have someone retrieve the wheel
chocks .
(D Tips
If you move the selector lever of the auto ­
matic transmission to P before applying
the parking brake and before blocking the
whee ls, you may have to use more force
later to move the lever out of the P posi­
tion.

196 Vehicle care and cleaning
A WARNING
-Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk
of accidents .
- To reduce the risk of cuts, protect your­
self from sharp metal components when
washing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef­
fect may be delayed due to moisture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applications.
(!;) Note
- If you wash the vehicle in an automatic
car wash, you must fold the exterior mir­
rors in to reduce the risk of damage to
the mirrors. Power folding exterior mir­
rors* must only be folded in and out us­
ing the power folding function.
- To prevent paint damage, do not wash
the vehicle in direct sunlight.
- To reduce the risk of damage, do not wash the power top with a pressure
washer. -
To reduce the risk of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:
- To reduce the risk of damage to the
surface, do not use polishing agents or
hard wax.
- Never use car wash cycles that apply
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 could be
damaged when the stickers or magnets
are removed.
@ For the sake of the environment
Only wash the vehicle in facilities specially
designed for that purpose. This will reduce
the risk of dirty water contaminated with
oil from entering the sewer system.

Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tive ly small patch of rubber on each tire that
assures that a ll-impo rtant contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separat ion and blowouts.
Avoiding damage I f you have to drive over a curb or similar ob­
stacle, drive very s low ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chem ica ls includ ing gre ase, o il,
gasoline and b rake fluid off the ti res .
Inspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
install t hem.
When removed, the whee ls or t ires should be
stored in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on r ims, in a horizontal pos it ion if
they are mounted on rims. New tire
s
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is ofte n not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one s ide, th is may ind icate
t h at one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au ­
tho rized Aud i dea le r or q uali fied wor ks hop.
Unidirectional t ires
A un idirectional tire can be identified by ar­
rows on the s id ewa ll, that po int in the direc­
t ion the t ire is desig ned to rotate. You mus t
f ol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characterist ics regarding grip,
road no ise, wear and hyd rop laning resistance.
For more information
¢ page 249.
A WARNING
-New tires or tires that are o ld, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
also be broken-in. To reduce t he risk of
losing control, a collision and se rious
pe rsonal injuries, drive w it h specia l care
for the first 350 miles (560 km).
- Driving with worn or damaged tires can
le ad to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
fl ation, c rashes and seriou s personal in­
juries . Have wo rn or damaged t ires re­
p laced immediate ly .
- T ires age even if they are not being used
an d can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.
