2013 AUDI S8 check transmission fluid

Effect of w ate r and ro ad sa lt
In certain situa tions, for example after driving
through water, in heavy rain, after overnight
condensation 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 wit h 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 w ithout the
driver noticing and provides for better brake response time under wet condit ions.
The effectiveness of the brakes can be reduced
when the vehicle is dr iven o n 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 caut ious ap­
p lications of the brake¢&. -
Due to their surface characteristics, ceram ic
brake roto rs* absorb mo isture in such condi­
tions. This can cause a temporary reduction in
b rak ing fo rce compared to d ry brakes. You can
compensate for this by pressing the brake pedal harder .
Corrosion
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
on ly for short t rips with little use of the
brakes.
I f t he b rakes are not used frequently, or if co r­
rosion has formed on the dis cs, it is advisable
to clean
off the pads and discs by brak ing
firm ly a few times from a moderately high
speed ¢.&. .
Faults in the brake system
If you should notice a sudden increase in
b rake peda l travel, then o ne of the two bra ke
circuits may have failed~ .&..

Low br ake fluid level
Malfunctions can occu r in the bra ke system if
the b rake fluid level is too low. The brake fluid
level is monitored electronica lly.
Brake lining wear status
B rake lining wear may be checked by visual in­
spe ct ion of the condition of the brake pads
through the open ings in the wheel. If neces­
sary, the whee l may be removed for this in­
spection

_& WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range . Do not ride
the brakes or hold t he pedal down too
long o r too often. Th is could cause the
brakes to get hot and diminish braking
efficiency .
- Do not "ride the brakes" by rest ing you r
foo t on the pedal when you do not intend
to b rake . This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing thro ugh wa­
ter, dr iv ing in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumu late on the brake pads, lin ings,
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 on
salt- cove red roads without using your
brakes can a lso affect braking efficiency .
Clean
off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.

-Always make sure the transmission se­
lector lever (automatic transmiss ion) is
in "P" (Park position) and the park brake
