Intelligent Technology
When the hill descent assist is on, the current
driving speed, when your vehicle entered the in
cline is maintained. It is only possible to switch
on the assist when driving slower than 37 mph (60 km/h). The assist works between approxi
mately 2 and 19 mph (4 and 30 km/h). The driver
can increase or decrease the vehicle speed within
these limits by depressing the accelerator or brake pedal.
There must be however sufficient ground adhe
sion . The hill descent assist
cannot do its job if
the incline is icy or if the incline ground is loose
¢ ,&.
Active assistance at a specific speed up to about 19 mph (30 km/h) is shown in the instrument
cluster through a blinking indicator light •. The
indicator light shines continuously when in the
ready mode.
The system does not work at speeds between 19
and 37 mph (30 and 60 km/h) . The system is
then in the ready-mode. This is shown through
the LED turned on in the button . The system au
tomatically switched off when you drive faster
than 37 mph (60 km/h). The LED will also go out
in this scenario.
Hill descent assist is automatically activated un
der the following conditions:
- The LED in the button turns on ,
- the vehicle speed is lower than 19 mph (30 km/
h) ,
-the incline angle is at least around 10% .
A WARNING
-Always adapt your speed to the weather ,
road and traffic conditions . Do not let the
increased safety provided tempt you into
taking risks, because this increases the risk
of an accident.
- The hill descent assist system cannot over
come the laws of physics. Your driving style
must always be adapted to the current road
and traffic conditions.
- The hill descent assist may not be able to
hold your vehicle at a constant speed under
all conditions while driving on an incline (for
154
example if ground under the vehicle is
loose).
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first
250 mi (400 km). They
must be "broken in" first¢& . However, you can
compensate for the slightly reduced braking
force by pressing firmly on the brake pedal. Avoid heavy braking during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still sub
ject to wear, depending largely on operating con
ditions and driving habits¢,& . On vehicles that
are either driven mostly in stop-and-go city traf
fic or are driven hard, the brake pads should be checked by your authorized Audi dealer more of
ten than specified in the
Warranty & Mainte
nance booklet.
Failure to have your brake pads
inspected can result in reduced brake perform
ance.
On steep slopes, you should use the braking ef
fect of the engine. This way, you prevent unnec
essary wear on the brake system. If you must use
your brakes, do not hold the brakes down contin
uously. Pump the brakes at intervals.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Effect of water or road salt
In certain situations, for example after driving
through water, in heavy rain, after overnight con densation 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 applica
tions.
At higher speeds and with the windshield wipers
turned on, the brake pads press against the brake
rotors for a short amount of time. This action
which is not felt by the driver happens at regular .,.
intervals and fac ilitat es a better reaction time for
the brak es 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 th e brake rotors and brake pads must be worn
off first when the brakes are applied~&, .
Cor ro sion
Leaving the vehicle par ked for long periods of
time, low m ileage and avo iding heavy brak ing
can contribute to corros ion on the brake rotors
and dirty brake pads.
If you usually avo id heavy b raking or if there is
cor ros io n present , occasional heavy braking at
high speeds is recommended to clean the brake
rotors and pads~&, .
Brake system malfunct ion
if you notice that the bra ke pedal travel has sud
denly
go tten larger , the n a brake circu it may have
failed ~&. .
Low brake fluid level
When the brake flu id level is low , malfunct ions in
the brake system may occ ur. The brake flu id leve l
i s elect ronically mo nitored .
Brake booster
The brake booster amplifies the pressure you ap
p ly to the brake pedal.
It only works when the en
g ine is running ~&, .
Brak e lining we ar status
Brake lining wea r may be checked by visual in
spection of the condition of the brake pads
through the open ings in the wheel. If necessary,
the wheel may be removed for this inspection
~ page 213, Replacing wheels .
.8, WARNING
-New bra ke pads don 't have the best stop
ping power and must be "bro ken- in" dur ing
the init ial 250 m iles ( 400 km). Yo u can
compensate for this by p ressing the brake
peda l more firm ly . T his also applies later
when new pads are installed .
Intelligent Technology
- You shou ld pe rform braking maneuvers for
the purpose of cleaning the brake system
only if road condit ions permit . Other road
users must not be put at r isk -you may
cause an accident!
- Before descending a steep grade, reduce
speed and sh ift tra nsmission in to a lower
gea r or lower dr iving range . Do not r ide the
b rakes or hold the pedal down too long or
too often. Th is co uld cause t he b rakes to ge t
hot and dim inish b raking effic ien cy.
- D o not " ride the bra kes " by rest ing you r foot
on the ped al when you do no t intend to
brake . T his may ca use the brakes to ove r
heat, premature wear and increased stop
ping distance .
- Under cer tain clima tic and ope rating condi
tions such as passing t hrough water, driving
in heavy rain o r after washing the vehicle,
the effectiveness of the brakes can be re
duced. In winter, ice can accumu late on the
brake pads, lin ings, discs and drums . Care
fully apply brakes for a test . Brakes will d ry
and ice coat ings will be cleaned off after a
few ca refu l bra ke applications .
- Driving for an extended period of t ime on
salt-covered roads without using your b rakes can also affect braking eff icien cy.
Clea n off acc umulated salt coat ing fr om
b rake discs an d pads w ith a few careful
brake applicat ions .
- If you damage the front s poile r, or if you in
s t all a different spoiler, be s ure the a ir flow
to the front brakes is not obstructed. Other
wise the brake system could overheat reduc
ing the effectiveness of the ent ire brake sys
tem.
- Fai lu re of one brake circ uit w ill impa ir the
braking capability resulting in an increased
stopping distance . Avoid driving the vehicle
and have it towed to the nearest authorized
Aud i deale r or qualified worksho p.
- Never let the ve hicle roll to a stop with the
e ngine shut off.
- If the brake booster is not working, the
brake pedal must be pressed cons iderab ly
harder to make up for the lack of booster
assis tance .

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 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.
Ca re and cleaning
- To re duce the risk of damage to the surface,
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 po lishing 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 cou ld be damaged
when the stickers or magnets are re
moved .
@ For the sake of the environment
Only wash the vehicle in facili ties s pec ia lly de
s igned for that pu rpose. This will reduce the
r isk of dir ty wate r contam ina ted with o il from
