tive cruise control* is switched on.
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.

188 Driving and en vironm ent
8_ WARNING
After driving through water, mud, slush,
etc ., the brakes may be slow to take effect
because of wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it .
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t hr ough water .
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
-
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con­
trol system (catalytic conv ert er) is function ­
ing properly to ensure that your vehicle is run­
ning in on env ironm entally sound manner.
,,. Always use lead-free gaso line Q page 201,
Fuel supply .
,,. Never run the tank down a ll th e way to emp ­
ty.
,,. Never put too much moto r oil in your engine
Q page 211 , ~ Adding engine oil .
,,. Never try to push -or tow -start your ve hicle .
T he cata lytic converter is an eff ic ient "clean­
up" device built in to the exhaust system of
the vehicle . The catalytic converter burns
many of the polluta nts in the exhaust gas be ­
fore they are released into the atmosphe re . The exclus
ive use of unleaded f uel is critica lly
important for the life of the catalytic conv ert­
er and p roper funct ion ing of the eng ine .
A WARNING
=
-The temperature of the exhaust system
is high, both when driving and after stop­
p ing the eng ine .
- Never touch the exhaust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle i n
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ver ter or he at s hields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
CI) Note
- Be aware tha t just o ne tank filling with
leaded fu el w ill alre ady ser io usly de ­
grade the performance of the cata lytic
converter .
- Do not exceed the cor rect engine oil level
Q poge 211.
-Do not drive until the fuel t ank becomes
comple tely empty . The engine cou ld mis ­
fire . Unburned fuel could also get into
the exhaust system and th is co uld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is mov ing.
- Do not contin ue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
co uld result in overheating of the con­
verter, requir ing its replacement.

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.

After you have loosened a ll wheel bolts and
raised the vehicle off the ground, remove and
replace the wheel as follows:
Removing the wheel
.. Remove the topmost wheel bolt completely
with the
hexagonal socket in the screwdr iv­
er hand le (vehicle tool kit)
c::>fig. 195 and
set it aside on a
clean surface.
.. Screw the threaded end of the
alignment
pin
from the tool kit hand -tight into the
empty bolt hole
c::> fig . 196.
.. Then remove the other wheel bo lts as de­
scribed above. ..
Take off the wheel leaving the alignment pin
in the bolt hole
c::> (D.
Putting on the spare tire
.. Push the spare tire over the alignment pin.
.. Screw on the wheel bolts and tighten them
slightly using the hexagonal socket .
.. Remove the alignment pin and insert and
tighten the remaining wheel bolt slightly
like the rest.
.. Turn the jack handle counter-clockwise to
lower the vehicle until the jack is fully re­
leased .
.. Use the wheel bolt wrench to tighten all
wheel bo lts firm ly
c::> page 246 . Tighten
them
in a crisscross pattern, from one bolt
to the (approximately) opposite one, to keep
the wheel centered .
.. Perform the steps required after changing
the wheel
c::> page 245, After changing a
wheel.
The hexagonal socket makes it easier to re­
move the wheel bolts from the rim. Care
should be taken when removing the reversible
blade .
(D Note
When removing or installing the wheel,
the rim cou ld hit the brake rotor and dam­
age the rotor. Work carefu lly and have a
second person to help you.
(@ Tips
- When mounting tires with
unidirectional
tread design
make sure the tread pat­
tern is po inted the right way
c::> page 249.
- The wheel bolts should be clean and easy
to turn. Check for dirt and corrosion on
the mating surfaces of both the wheel
and the hub. Remove all d irt from these
surfaces before remounting the wheel.
- Do not use the hexagonal socket in the
screwdriver handle to loosen or t ighten
the whee l bolts .
