2015 AUDI A5 CABRIOLET brake rotor

Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Effect of water and road salt
In certain situat ions, for example after driving
through water, in heavy ra in, after overn ight con­
densat ion 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 carefu l brake applications.
At higher speeds and with the w indshie ld w ipers
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 accumulated salt coating from brake discs
and pads with a few cautious applications of the
brake ¢.& .
Corrosion
There may be a tendency for dirt to build 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 advisab le to
clean off the pads and discs by braking firmly a
few t imes from a moderately high speed¢.&.
Faults in the brake system
If you should notice a sudden increase in brake
pedal trave l, then one of the two brake circuits
may have failed

Low brake fluid level
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid leve l is
~ monitored e lectronically.

Brake booster
T he brake booster increases the pressure that you
generate w ith the brake pedal.

Brake lining wear status
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
through the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c:> page 230, Replacing wheels.
_8 WARNING "'---
-New brake pads don't have the best stop­
pin g power and must be "broken-in" during
the initial 250 miles (400 kilometers). You
can compensate for this by press ing the
brake pedal more firmly. This also applies
later when new pads are installed.
-
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system
only if road conditions permit. Other road
users must not be put at r isk -you may
cause an acciden t!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or
too often . This could cause the brakes to get
hot and diminish braking efficiency.
- Do not "ride the brakes" 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
p in g distance.
- Under certain cl imatic and operat ing condi­
tions such as passing through water, dr iv ing
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced. In winter, ice can accumulate on the
b rak e pads, linings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of time on
salt -covered roads wi thout using your
brakes can a lso affect braking efficiency .

Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 600 miles (1,000 kilometers ):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than
2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
"' Speeds can gradually be increased to the maxi­
mum perm issible road or engine speed.
During and after break-in period
"'Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break-in period
"'Do not exceed maximum engine speed under
any circumstances.
"'U pshift into the next higher gear
before reach­
ing the red area at the end of the tachometer
scale
c=> page 10.
During the first few hours of driving, the engine's
internal friction is higher than later when all the
moving parts have been broken in. How well this
break-in process is done depends to a considera­
ble extent on the way the vehicle is driven during
the first 1,000 miles (1,500 kilometers).
(D Note
Extremely high engine speeds are automati­
cally reduced. However, these rpm limits are
p rog rammed for an engine wel l run- in, not a
new engine.
@) For the sake of the environment
Do not dr ive with unnecessarily high eng ine
speeds -upshifting early saves fuel, reduces
noise and protects the environment.
Driving and the environment
New tires
If your vehicle is running on new tires, drive very
carefully for the fi rst 350 m iles (500 kilometers)
after fitting .
New tires tend to be slippery and must also
be "broken-in". Be sure to remember this dur­
ing the first
350 miles (500 kilometers).
Brake gently. Avoid following closely behind
other vehicles or other situations that might
require sudden, hard brak ing .
Avoid damaging the
vehicle
When you are d riving on poor roads, or over
curbs, steep ramps, etc., ma ke certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
T his is espec ially true for veh icles with low-s lung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on
roads
Note the following to avoid vehicle damage when
driving through water, for example on f looded
roads:
- The water must not be any higher than the bot­
tom of the vehicle body.
- Do not drive faster than walking speed.
A WARNING
= -
After driving through water, mud, slush, etc.,
the brakes may be s low to take effect because
of wet brake rotors and pads. Dry the brakes
first by braking carefully to restore the full braking effect.
(D Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water . ""

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 braking effect
may be delayed due to moisture on the
brake rotors or ice in the w inter. The brakes
must be dried first w ith a few careful brake
applications.
- If you wash the vehicle in an automatic car
wash, you must fold the exterior m irrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be fo lded in and out us ing the power folding
funct ion.
- To prevent pa int damage, do not wash the
vehicle i n direct sunlight.
- To reduce the risk of damage, do not wash
the power top with a pressure washer.
Care and cleaning
-To reduce the risk of damage to the sur face,
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 polishing agents or hard
wax.
- Never use protect ive wax. It can destroy
the matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted w ith matte
f inish paint. The pa int could be damaged
when the stickers or magnets are re­
moved .
@ For the sake of the environment
Only wash the vehicle in facilities spec ially de­
s igned for that purpose. This w ill reduce the
r isk of di rty water contaminated w ith oil from
entering the sewe r system.

After you have loosened all wheel bolts and
ra ised the veh icle off the ground, remove and re­
p la ce the whee l as follows:
Removing the wheel
"' Remove the topmost wheel bolt completely
with the
hexagonal socket in the screwdriver
handle (vehicle tool kit)
r=;, fig. 191 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 bo lt
hole
r=;, fig . 192.
"' Then remove the other wheel bo lts as described
above.
"' Take off the wheel leaving the alignment pin in
the bolt hole
r=;,(I).

Putting on the spare tire
"'Push the spare tire over the alignment pin.
"' Screw on the wheel bolts and tighten them
slightly using the hexagona l socket .
"' Remove the alignment pin and insert and tight­
en the remaining wheel bolt slightly like the
rest.
"' Turn the jack hand le counter-clockwise to lower
the vehicle until the jack is fully released .
"' Use the wheel bolt wrench to tighten all wheel
bolts firmly
r=;, page 232. Tighten them in a
crisscross pattern,
from one bolt to the (ap­
proximately) opposite one, to keep the wheel
centered.
"' Perform the steps required after changing the
wheel
r=;, page 231, A~er changing a wheel .
The hexagonal socket makes it easie r to remove
the wheel bolts from the rim. Care should be tak­
en when removing the reversib le blade .
(D Note
When removing or installing the wheel, the
rim could hit the brake rotor and damage the
rotor. Work carefully and have a second per­
son to he lp you.
(D Tips
- When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way
r=;, page 235.
- 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 dirt from these surfaces be­
fore remounting the wheel.
- Do not use the hexagonal socket in the
screwdriver handle to loosen or tighten the
wheel bolts.
