\.J ' intervals and ensures a better reaction time fo r
the brakes in wet weather.
The braki ng effect can also be red uced if you are
driving on salted roads and you do not apply the b rakes for long periods of time . The layer of salt
on the brake rotors and pads must be worn off
f irst when the brakes are app lied.
Due to its surface, the ceramic bra ke rotor* ab­
sorbs moisture in certa in situations. There fore,
there will temporarily be less braking force than
when the brakes are dry . You can compensate for
this by pressing the brake pedal harder.
Cor rosion
L eaving the vehicle parked fo r long periods of
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads.
I f you usually avo id heavy braking or if there is
corrosion present , occasional heavy braking at
high speeds is recommended to clean the brake
rotors and pads
q ,& .
Brak e system malfunct ion
if you notice that the brake pedal travel has sud­
denly increased, then a brake c ircui t in the dual­
circuit brake system may have malfunctioned. Drive to an authorized Audi dea ler or a uthorized
Aud i Service Facility immediately to have the
problem corrected. On the way there, drive with
reduced speed and keep in mind that you w ill
need a longer distance to stop and you w ill need
to p ress the b rake pedal harde r.
L ow brake fluid level
When the brake fl uid level is low, malfunct ions in
the brake system may occur . The brake f lu id level
is electronically monitored.
Br ak e boost er
The brake booster amplifies the pressure you ap­
p ly to the brake peda l. It only works when the en­
g ine is running.
A WARNING
- Only apply the brakes for the purpose of
cleaning the brake system whe n road and

traffic conditions permit. You must not en­
danger other road users. This increases the
risk of an accident.
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
- New brake pads do not ach ieve the ir full
braking effect during the first 250 m i
(400 km). They m ust be "broken in" first.
The break-in per iod ca n be cons iderably lon­
ge r fo r vehicles with ceram ic brake rotors* .
H owever, you can compensate fo r the
slightly reduced braking force by pressi ng
fi rm ly on the brake pedal. Avo id heavy b rak­
ing du ring the break -in pe riod.
- Ce rtain weathe r and ope rating condi tions
such as driving through water, dr iv ing in
heavy rain o r driv ing after was hing your ve­
hicle can impa ir the effect iveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums . Check
these components by braking carefully. Ap­
p lyi ng the brakes carefully several times
d ries the b rakes and removes ice build-up .
- The efficiency of the brakes can also be im­
pa ired by dr iv ing for long stretches on roads
covered with sa lt without using the bra kes .
You can remove salt deposits from the
b rake rotors and pads by carefully applying
t he brakes several times .
- I f the fron t spoiler is damaged o r yo u install
another spoi ler, make su re the front wheel
b rakes are ven tilated properly . Othe rw ise,
the brake system co uld overheat, which re­
duces their effectiveness .
- Fa ilure of a brake circuit impairs brak ing
pe rformance, which increases b raking dis­
tance. Avo id driving the vehicle and have it
towed it to the nearest a uthorized Audi
deale r or authorized Aud i Serv ice Facility.
- I f the brake booster is not working, yo u w ill
have to p ress much harder on the brake
pedal to compensate fo r the lack of the
booster.
Q) Note
- Never let the brakes "rub" by pressing the
peda l lightly when braking is not actually

necessary. This causes the brakes to over ­
heat and increases bra king distance and
causes wear .
- Befo re driving downhi ll a long distance on a
steep hill, decrease your speed and select a
l ower gear. This makes use of the engine
braking effect and relieves the brakes. If
you need to brake additionally, b rake in in­
t e rvals a nd not continuously .
(D Tips
-If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit you r vehicle with a front spoil­
e r, whee l covers o r similar items , make sure
that the a ir flow to t he fron t wheels is not
i nte rr u pted . Othe rw ise the brake sys tem
ca n become too hot .

Glossary of tire and loading
terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto­ matic t ransmission, power steer ­
ing, power brakes, power win­
dows , powe r seats, radio, and
heater, to the extent tha t these

Maximum (permissible )
inflat ion pressure
means the maximum cold infla­
tion pressure to wh ich a t ire may
be inflated. Also called "maxi­
mum inflation pressure ."
Normal occupant weight
means 150 lbs . (68 kilograms)
times the number of occupants
seated in the veh icle up to the to­
tal seating capacity of your vehi­
c le .
Occupant distribution
means distribution of occupants
in a vehicle.
Oute r diameter
means the overall diameter of an
inflated new tire .
Overall width
means the linear distance be­
tween the exteriors of the side­
walls of an inflated tire, including
elevations due to labeling, deco­
rations, or protective bands or
ribs.
Ply
means a layer of rubber-coated
parallel cords.
Wheels
Production options weight
means the combined weight of
those installed regular production
options weighing over 5 lbs. (2.3
kg) in excess of those standard
items which they replace, not pre­
viously considered in curb weight
or accessory weight, including
heavy duty brakes, ride levelers,
roof rack, heavy duty battery, and
special trim .
Radial ply tire
means a pneumatic tire in which
the ply cords that extend to the
beads are laid at substantially 90
degrees to the centerline of the
tread.
Recommended inflation
pressure

tion pressure.
Reinforced tire
means a tire designed to operate
at higher loads and at higher in ­
flation pressures than the corre­
sponding standard tire. Rein­
forced tires may be identified as
"X L", "xl", "EXTRA LOAD", or "RF"

plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle . If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load .
The
Gross A xle Weight Rating
("GAWR") is the maximum load
that can be appl ied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi ­
c le Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a tra iler hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.

_& WAR NING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal in jury, and even death.
-Carrying more weight than
your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
- The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to­
tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer - does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating .

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 acci­
dents.
- 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 braking effect
may be delayed due to mo isture on the
brake rotors or ice in the winter . This in­
creases the risk of an acc ident. The brakes
must be d ried first w ith a few careful b rake
applications.
(D Note
- If yo u wash the ve hicle in an automatic car
wash, yo u m ust retract the rear spoiler if
necessary, and fold the exte rior mi rrors in
to reduce the risk of da mage. Power fo ld ing
ex ter ior mirro rs* m ust only be folded in and
out using the power folding func tion.
-
- To red uce the risk of pa int damage, do not
wash the vehicle in direct sun light .
- T o reduce the risk of damage to the s urface,
do not use insect removing sponges, kitchen
sponges o r similar items .
- Matte finish painted vehicle components:
-To reduce the risk of damage to the sur-
face, do not use polis hing 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 could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment
Only wash the veh icle in facili ties spec ially de­
s igned for that pu rpose . This will reduce the
r isk of dirty wate r contam inated with o il from
ente ring the sewe r system.
