" Press the button again to switch it off. The di-
ode in the button will go out .
Hill descent ass ist brakes all four wheels auto
matically in order to limit speed when driving ei
ther forwa rd o r reverse on hills with a grad e up to
approximately 50%.
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 app roxi
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 In addition, vehicle steerability is in
creased due to the braking distribution when
driving in reverse .

- the incline is 10%.
& WARNING
-Always adapt your speed to the weather,
road and traffic cond itions. Do not let the
increased safety provided tempt you into
taking risks.
-
-The hill descent assist system cannot over
come the laws of phys ics. Your driving style
must always be adapted to the current road
and traffic conditions.
- The hill descent assist may not be ab le to
hold your vehicle at a constant speed under
all cond itions wh ile driving on an incline (for

loose).
Braking
What affects braking efficiency?
New brake pads
Du ring the first 2 50 miles (400 km), new brake
pads do not possess their full braking effect, they
have to be "broken in" first
c:> &. ..,_

,....,
The brakes on today 's au tomobiles a re still s ub
ject to wea r, depend ing la rgely on ope rating con
ditions and driving habits¢.&. . On vehicles that
ar e e ither driv en most ly in stop-and -go city traf
f ic or are driven ha rd, the brake pads should be
checked by your authorized Aud i dealer more of
ten than specified in the
Warranty & Mainte
n ance boo klet .
Failure to have your brake pads
inspected can resu lt in reduced brake perform
ance.
On steep slopes, you should use the braking ef
fect of the eng ine . This way, you prevent unnec
essary wear on the brake system . If you must use
your b rakes , do not ho ld the brakes down con tin
uously. Pump t he b rakes at intervals.
Operating noise
Noises may occur when braking depend ing on the
speed , braking force and outs ide cond itions such
as tempe rature and humidity .
Effect of water and road sa lt
In certain situations, for example a fter driving
t hrough water, in heavy ra in , after overnight con
densat ion or after washing your car, the braking
effect can be reduced by moisture or ice on the
b rake rotors and b rake pads . T he brakes must be
d ried first w ith a few careful b rake applica tions.
At highe r speeds and with the windsh ie ld w ipers
turned on, the bra ke pads press aga inst the brake
rotors for a short amount of time . Thi s occ urs at
r egular intervals wit hout the d river noticing and
p rovides for be tter br ak e response time u nder
wet conditions.
The eff ectiv eness of the brakes can be reduced
when the vehi cle is dr iven on a salt-covered road
and the brakes are not used. L ikewise, you clean
off acc umu la ted salt coat ing from b rake discs
and pads with a few ca utious applications of the
b rake ¢.&. .
Corrosion
There may be a tende ncy for d irt to b uild up on
the brake pads an d cor ros io n t o fo rm on the discs
if the ca r is not driven regular ly or only fo r sho rt
trips with little use of the brakes .
Intelligent Technology
If
the brakes are not used frequent ly, or i f co rro
sio n has formed on the discs , it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed ¢ .&, .
Faults in the brake system
If you shou ld notice a sudden inc rease in brake
peda l travel, t hen one of t he two brake circ uits
may have fai led ¢
&..
Low brake fluid level
Malfunctions ca n occur i n the b rake system if the
br ak e fluid level is too low . T he brake f lu id leve l
is moni tored elect ronically .
Brake booster
The brake booster increases the press ure that
yo u generate with the b rake peda l.
It only oper
ates while the eng ine is r unning or w it h t he igni
tio n sw itched on (hybr id drive*) ¢.&, .
Brake lining wear status
Brake lining wear may be chec ked by visual in

.&_ WARNING
--
-New brake pads don't have the bes t stop
p ing power an d m ust be " broken-in" d uring
the initial 250 miles (400 km). You can compensate for this by pressing the brake
pedal more firmly. This also applies later
when new pads are insta lled.
- You sho uld perform braking maneuvers for
the purpose of cleaning t he brake system
only if road condit io n s pe rmit . O ther road
users m ust not be put at r is k - you may
cause an accident!
- Before descending a steep g rade, reduce
speed and sh ift transmission into a lower
gea r or l ower dr iv ing ra nge. Do not r ide the
b rakes or hold the ped al down too long or
too often. This co uld cause t he b rakes to ge t
hot and dimi nish braking eff ic ien cy .
- Do no t "ride the br akes" by res ting you r foot
on the pedal when you do no t intend to ...,

Intelligent Technology
brake. This may cause the brakes to over
heat, premature wear and increased stop
ping distance.
- Under certain climatic and operating condi
tions such as passing through water, driving
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re duced . In winter, ice can accumulate on the
brake 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 without using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few carefu l
brake app lications .
-If you damage the front spoiler, or if you in
stall a different spoiler, be sure the air flow
to the front brakes is not obstructed. Other
wise the brake system could overheat reduc ing the effectiveness of the entire brake sys
tem .
- Failure of one brake circuit will impair the
braking capability resulting in an increased
stopping distance. Avoid driving the vehicle and have it towed to the nearest author ized
Audi dealer or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considerably
harder to make up for the lack of booster
assista nee.

Driving tips
On poor rood ond offroad, there is always only
one motto: Plan ahead and drive slowly!
Pl ease observe the following when driv ing away
from paved roads:
.,. Drive only on roads and off road sections which
ma tch the des ign of your vehicle and yo ur abili
ties as a driver . Neve r take risks!
... Drive slowly and p lan ahead!
... Take into consideratio n the
ground clearan ce
of your veh icle.
.,. Activate the
offro ad mode Q page 190 as need
ed .
.,. Use the
hill desc ent a ssis t Q page 192 when
driv ing down steep sections on hills .
Unpaved roads and offroad
Drive s low ly on unfam iliar roads and unknown
offroad sections, and look out for unexpected ob
stacles (e .g. potholes, rocks, tree stumps, etc .) .
To prevent the veh icle from bottoming and avoid
damage to the underbody, you should d rive
stra ight across severe bumps in the ground with
only one side of the vehicle so that only two of
your wheels cross the b umps.
Drive briskly through sandy or marshy offroad
sections and do not stop , if at all possible .
Driving through water
Note the following to avoid vehicle damage when
driving throug h water, fo r example on flooded
roads:
- T he wate r must no t be any higher than the bot-
tom of the vehicle body .
- Do no t drive fas ter than wa lking spee d.
Driving on a slope
If you ever find yo urself not able to cl imb a s lope,
do not try to turn around, d rive back down in
re
verse .
Otherw ise, you run the risk of tipping over.
202 If the vehicle thre
atens to tip o ver when dr iving
across a slope, you must immediately stee r
downhill in the direction of the slope.
Do no t pa rk you r vehi cle on steep s lopes or
grades .
To reduce the risk of tipping over, drive on slopes
i n the d irect io n of the downwa rd slope (fa ll line) -
not cros swi se .
& WARNING
After driving thro ugh water, mud, slush, etc.,
the brakes may be slow to take effect beca use
of wet brake rotors and pads. Dry the brakes
f irst by braking carefu lly to restore the full
braking effect .
(D Note
- Vehicle components such as the engine,
transmiss ion, suspension or electrical sys
tem can be seve rely damaged by driving
throug h water.
-Always switch off the Start-Stop-System *
when driving through water Qpage 93.
(D Tips
-Check the de pth of the water before driving
through it.
- Do not stop the vehicle, drive in reverse or
switch the engine of f whe n driving through
water.
- Keep in mind that oncom ing vehicles may
create waves that raise the water level and
make it too deep fo r your vehicle to drive
t h roug h safe ly.
-Avoid driv ing through salt water beca use it
can cause corrosion.

Changing brake fluid
Have the brake fluid changed by an experienced technician.
Brake fluid absorbs mo isture from the air. If the
water conte nt in the brake fluid is too h igh, cor
ros ion in the brake system may resu lt after ape
riod of time. The boiling poi nt of the brake flu id
will also dec rease cons iderably and decrease
braking pe rformance.
Therefore, the b rake fluid must be changed
e ve ry
two year s.
Always use new b rake fluid wh ich con
forms to Fede ral Motor Veh icle St andard "FMVSS
116 DOT 4".
The brake fluid reservoir can be diff icult to reach,
therefore, we re commend that yo u have the
b rake fl uid changed by yo ur autho rized
Audi
deal er.
Your dealer has the cor rect too ls, the
right brake fluid and the know -how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of chi ldren!
- B rake failure can resu lt from old or inappro
pr iate brake flu id. Observe these precau
t io ns:
Ch eck ing and Filling
-Use only brake fluid that meets SAE speci
ficat ion
J 1703 and conforms to Federal
Motor Vehicle Standard 116. Always check
with your authorized Aud i dealer to make
sure you are us ing the correct brake fluid .
The co rrect type of brake flu id is also i ndi
cated on the b rake fluid reservoir.
- The brake flu id must be new. Heavy use of
the b rakes can cause a vapo r lock if the
bra ke fluid is left in the system too long.
T his can se riously affe ct the efficiency of
t h e b rakes as we ll as you r safety . This
could resu lt in an accident.
(D Note
B rake flu id will damage the paint of your ve h i
cle.
@) For the sake of the environment
Because of the p roblem of proper d isposa l of
brake fluid as well as the spec ial too ls re
q uire d and the necessary expertise, we rec
ommend that yo u have the bra ke fluid
c hanged by yo ur authorize d Au di dealer.
