Noises may occur when braking depend ing on the
speed, braking force and outside conditions such
as temperature and humidity.
Eff ect of wat er and road salt
In ce rtain situations, for example after dr iving
through water, in heavy ra in, afte r ove rnig ht con
densat io n or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
dried first with a few careful brake applications .
At highe r speeds and with the windsh ie ld wipers
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 driven on a salt-covered road and the brakes are not used . Likewise, you clean
off accumu lated salt coating from brake discs
and pads with a few cautious applications of the
brake ~,&. .
Cor ro sion
There may be a tendency for dirt to b uild up on
the brake pads and corros ion to form on the discs
if the car is not driven regularly or only for short
tr ips with little use of the brakes .
If the brakes are not used frequently, or if corro
sion has formed on the discs, it is adv isable to
clean off the pads and discs by braking firmly a
few t imes from a moderately high speed

Fa ults in the brake sy stem
If you should notice a sudden increase in brake
pedal travel, then one of the two brake circuits
may have failed

Low brak e fluid level
M alfunct ions can occur in the brake system if the
b rake fluid leve l is too low . The brake fluid level
is monitored e lectronically .
Intelligent Technology

Brake lining wear status
B rake lining wea r may be chec ked by visua l in
spe ct ion of the condi tion of the brake pads
t hr ough the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c:> page 2 26, Replacing wheels .
_8 WARNING "'---
-New brake pads don't have the best stop
ping power and m ust be "broken-in" during
the initial 250 miles (400 kilometers). You can compensate for this by p ressing the
brake pedal more firmly . This also app lies
later when new pads are installed.
-
- You shou ld pe rform braking maneuvers for
the purpose of cleaning the brake system
only i f road condit ions pe rmit . Other road
users m ust not be put at r is k -you may
cause an ac ciden t!
- Before descending a s teep g rade , reduce
speed and sh ift tr ansmi ssion into a lower
gear or lower dr iving range. Do not r ide the
brakes or hold the pedal down too long or
too often. This co uld cause the brakes to get
hot and dimin ish braking eff ic iency.
- Do not "ride the bra kes" by resting your foot
on the pedal when you do not intend to brake. This may cause the brakes to over
heat, premature wear and increased stop
ping distance.
- Unde r ce rtain climatic and operating condi
tions such as passing through water, driving in heavy rain or after wash ing the veh icle,
the effectiveness o f the brakes ca n be re
duced. In winter, ice can accumu late on the
brake pads, lin ings , d is c s and dr ums . Care
fu lly apply br akes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful bra ke applications .
- Driving for an extended period of time on
salt -covered roads without using your
brakes can also affect braking eff iciency .
173

Intelligent Technology
Clean off accumulated salt coating from
brake discs and pads with a few caref ul
brake app lications.
- If you damage the front spoiler, or if yo u in
stall a d ifferent spoiler, be sure the air flow
to the front brakes is not obstructed. Other
wise the brake system could overheat reduc
ing the effectiveness of the entire b rake sys
tem.
- Failure of one brake c ircuit will impair the
bra king capability res ult in g in an increased
stopp ing distance. Avoid driving the vehicle
and h ave i t towe d to the ne arest author ized

Winter t ire s
When driving in the winter, your vehicle with a ll
wheel drive has an advantage, even with regular
tires. In winter road conditions it may be adv isa
ble to mount w inter tires (or all-season tires) for
i mproved driveab ility and brak ing : these tires
must be mounted on
all four wheels . See also

Tire chains
Where tire chains are mandatory on certain
roads, this normally also applies to vehicles w it h
all -wheel drive <=>

Replacing wheels /tires
Vehicles with all-whee l dr ive must always have
tires of the same size. A lso avoid tires with differ
ent tread depths. For details see page
<=>
page 212, New tires or wheels.
Off-Road dri ving ?
Your Aud i does not have enough ground clear
ance to be used as an off-road vehicle.
It is there
fore best to avoid rough tracks and uneven ter rain as much as possible . Also refer to

A WARNING
Always adjust your driving to road and t raff ic
conditions. Do not let the extra safety affo rd
ed by all-wheel drive temp t yo u into ta king
extra risks.
- Although the all-whee l drive is very effec
t ive, a lways remember th at br akin g capac ity
is limited by tire traction. Yo u should t here
f ore not drive at excess ive speeds on icy or
slippery road surfaces.
- On wet road surfaces, be caref ul no t to drive
too fast because the front wheels co uld be

Trailer mode notes
Important to know
Your vehicle handles different ly when tow ing a
trailer because of the additional weight and d if
ferent weight distr ibution. Safety, perfo rmance
and economy will greatly depend on how careful
ly you load your trailer and operate your rig .
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traffic. Keep practicing until you have be
come completely familiar with the way your vehi
cle-trailer combination behaves and responds.
Backing up is difficult and requires pract ice.
Backing up with a trailer generally requires steer
ing action opposite 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 will need more
room to stop. To compensate for the trailer, you
will need a larger than normal turning radius.
When pass ing, 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 trai ler before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D 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
c::> page 244.
Parking on a slope
Do not pork on a slope with a trailer. If it cannot
be avoided, do so only ofter doing the following:
When parking:
;::; .. Apply the foot brake.
0 ~ .. Have someone place chocks under both the ve-
~ hicle and the trailer wheels. Lil ,...., v:, ,....,
Trailer mode
.. 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.
.. Place an automatic transmission* in P, respec
tively a manual transmission in first or reverse
gear .
When restarting after parking:
.. App ly the foot brake.
.. Start the engine .
.. Move the selector lever to D/S, respectively a
manual transmission in first gear .
.. Release the parking brake and slowly pull out
and away from the wheel chocks.
.. Stop and have someone retrieve the wheel
chocks.
(D Tips
If you move the selector leve r of the automat
ic transmission* to P before applying the
parking brake and before blocking the wheels,
you may have to use more force later to move
the lever out of the P position.

- 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 . The brakes
must be dried first w ith a few careful brake
applica tions .
- If you wash the vehicle in an automatic car
wash, yo u m ust fold the exterior m irrors i n
to reduce the risk of damage to the mirrors.
Power folding exte rior m irrors* must on ly
be fo lded in a nd out using the power folding
funct ion.
- To p revent paint damage, do not wash the
vehicle i n direct sunlight.
- To reduce the risk of damage to the surface,
do no t use insect remov ing s ponges, kit chen
spo nge s or similar i tems .
- M atte fi nish pa inted vehicle components :
- To red uce the risk of damage to the s ur-
face, do not use polishing agents or hard
wax.
- Never use protect ive wax .
It can dest roy

- Do not place any stickers o r magnet ic
signs on vehicle pa rts pa inted with matte
fin is h pa int. The paint could be damaged
when the stickers or magnets are re moved .
@ For the sake of the environment
Only wash the vehicle in facilities specially de
signed for that purpose. This will reduce the r isk of dirty water contaminated with oil from
entering the sewer system .
