ther fo rward or reverse on hills with a grade up to
approximately 50%.
When the h ill descent assist is on, the current
d riving speed, when your vehicle entered the in­
cline is maintained.
It is only possible to switch
on the ass ist when d riving slower than 37 mph
(60 km/h). The assist works between app rox i­
mately 2 and 19 mp h (4 and 30 km/h). The driver
can increase or decrease the vehicle speed within
these limits by depressing the acce lerator or
brake pedal In addition , vehicle steerability is in­
creased due to the braking distribution when

- the incline is 10% .
A WARNING
-
-Always adapt your speed to the weather,
road and traffic conditions. Do not let the in ­
creased safety provided tempt you into tak­ ing risks.
- The hill descent assist system cannot over­
come the laws of physics . Your driving style
must always be adapted to the current road

- The hill descent assist may not be ab le to
hold your vehicle at a constant speed under
all conditions w hile driving on an incl ine (for
example if ground under the vehicle is loose) .
Braking
What affects broking efficiency?
New brake p ad s
During the first 250 miles (400 km), new brake
pads do not possess their full braking effect, they
have to be "broken in" first¢ &. .,,.
193

Smart Technolog y
Operating c ondit ion s and drivin g hab it s
The brakes on today 's automobi les are st ill 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
f ic or are driven hard, the brake pads should be
checked by your authori zed Audi dealer more of­
ten than specified in the
Wa rra nty & Mainte­
n an ce boo kle t .
Fa ilure to have your brake pads
inspected can result in reduced brake perform­
ance.
On steep slopes, you should use the brak ing ef­
fect of the eng ine . Th is way, you prevent unnec ­
essary wear on the brake system. If you must use
your brakes, do not ho ld the brakes down contin­
uously. Pump the brakes at inte rva ls.
Operat ing no ise
Noises may occur when braking depending on the
speed, brak ing force and outside conditions such
as temperature and humid ity .
Effect of w ate r an d r oad sal t
In certain situations, for example after driving
through water, in heavy rain, after overn ight con­
densat ion or after washing your car, the braking
effect can be reduced by mo isture or ice on the
brake rotors and brake pads . The brakes must be
d ried first with a few carefu l brake applications.
At h igher speeds and with the w indshield wipers
turned on, the brake pads press against the brake rotors for a short amount of t ime . This occurs at
regular intervals without the d river noticing and
p rov ides for better brake response t ime unde r
wet conditions .
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered road
a nd the brakes are not used . L ikew ise, you clean
off accumulated sa lt coating from brake discs
and pads with a few cautious applications of the brake ¢.&. .
Corros ion
There may be a tendency for dirt to bui ld up on
the brake pads and corros ion to fo rm on the discs
if the car is not driven regularly or on ly for short
trips with litt le use of the brakes.
194
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisable to clean off the pads and d iscs by braking firmly a
few times from a moderate ly high speed¢.&. .
Fault s in the brak e system
If you shou ld notice a sudden increase in bra ke
pedal travel, then one of the two brake circuits
may have failed
¢ .&. .
Lo w b rake fluid l evel
Malfunctions can occur in the brake system if the
brake flu id leve l is too low. The brake fl uid level is
monitored electronica lly.
Brake boos ter
The brake booster increases the pressure that you
generate w ith the brake pedal. It on ly operates
whi le the engine is runn ing o r with the ig nit ion
switched on (hybrid drive*)
¢ ,& .
Brake lining we ar status
Brake lining wear 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 inspec tion
¢ page 260, Replacing wheels .
& WARNING -
- New brake pads don't have the best stop­
ping power and m ust be "broken-in" during
the initial 250 miles (400 km) . You can com­
pensate for this by pressing the brake pedal
more f irm ly. This also applies later when
new pads are installed.
- 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 r isk -you may
cause 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
bra kes or ho ld the peda l down too long or
too often . This could cause the bra kes 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

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 wate r, driving
in heavy rain o r after washing the vehicle,
the effectiveness of the brakes can be re­ duced. In w inter, ice can accumulate on the
brake pads, linings, discs and drums . Care­
fully apply b rakes for a test. B rakes wi ll dry
and ice coatings wi ll be cleaned off after a
f ew caref ul bra ke applications .
- Dr iv ing for an extended period of time on
salt-covered roads w ithout using you r
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads w ith a few caref ul
brake applicat ions.
- If you damage the front spoiler, or if you in­
stall a different spoi ler, 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 ent ire brake sys­
tem .
- Failure of one brake c ircuit will impair the
braking capab ility result ing in an increased
stopp ing distance. Avoid driv ing the veh icle
and have it towed to the nearest authori zed
Audi dealer or qu alified workshop.
- Never let the vehicle roll to a stop w ith the
eng ine shut off.
- If the brake booster is not work ing, the
brake pedal must be pressed conside rably
harder to make up fo r the lack of booste r as­
sist ance.

Driving tips
On poor road and offroad, there is always only
one motto: Plan ahead and drive slowly!
P lease observe the followin g when driving away
from paved roads :
~ Drive only on roads and off road sections which
match the des ign of your veh icle and yo ur abili ­
t ies as a driver . Never take risks!
~ Drive slowly and plan ahead!
~ Take into consideration the gr ou nd cle aran ce of
your vehicle.
~ Activate the offroad mode c> page 191 as need­
ed .
~ Use the hill des cent a ssi st <=:> page 193 when
dr iv ing down steep sections on hi lls.
Unp aved roads and offroad
Drive s low ly on unfami liar roads and unknown
offroad sections, and look out for unexpected ob­
stacles (e.g . potho les, rocks, tree stumps, etc .) .
T o prevent the vehicle from bottoming and avoid
damage to the underbody, you should drive
straight across severe bumps in the ground with
only one side of the vehicle so that only two of
your wheels cross t he bumps.
Drive briskly through sandy or marshy offroad
sections and do not stop, if at all poss ible.
Driving through water
Note the following to avoid vehicle damage when
driving through water, for example on flooded roads:
- The water must not be any higher than the bot-
tom of the vehicle body .
- Do no t d rive fas ter than wa lking speed.
Driving on a slope
If you ever find yourself not ab le to climb a s lope,
do not try to turn around, drive back down in
re­
ver se.
Othe rwise, you ru n the r isk of tipp ing ove r.
O ffro ad dri vin g
If the vehicle th reaten s to tip over when driving
acro ss a slope, you must immediately stee r
downhill in the direction of the slope.
Do not park you r vehi cle on steep s lopes or
grades.
T o reduce the risk of tipp ing ove r, d rive on s lopes
i n the d irection of t he downwa rd s lope (fall li ne) -
not cro sswi se .
& WARNING ~ -
After driving th rough water, mud, s lush, etc.,
the bra kes may be s low to take effect because
of wet bra ke rotors and pads. Dry the brakes
f irst by brak ing carefully to restore the full
braking effect.
(D Note
- Veh icle components s uch as the engine,
transm ission, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Always switch off the Start-Stop-System *
when drivi ng throug h water
r=> page 94.
(D Tips
- Check t he depth of the water before driving
through it.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driv ing through
water.
- Keep i n mind that oncoming veh icles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely .
-Avo id driving through salt wate r because it
can cause corrosion .

Checking and F ill in g
The brake fluid reservoir is located at the rear
partition of the engine compartment on t he left
side ¢
page 223.
The fl uid level may drop slightly after some time
due to the automatic adjustment of the brake
pads. This is not cause for alarm.
If the b ra ke fluid level fal ls considerably below
the "MIN" mark, the brake warn ing/indicator
light (U.S. models:
1111 , Canadian models: . )
will come on¢
page 18 and ¢ page 28 . Do not
continue to operate the vehicle . The complete
brake system shou ld be thoroughly checked by an
author ized Audi dealer or qualif ied workshop and
the cause corrected. If the brake fluid level is too low, the brake warning/indicator light will illum i­
nate. Contact an authorized Aud i dealer
immedi ­
a tel y.
Changing brake fluid
Have the brake fluid changed by an experienced technician.
Brake flu id abso rbs moisture from the a ir . If the
water content in the brake fluid is too high, cor­ rosion in the b rake system may result after a pe ri­
od of time. The boiling point of the bra ke fluid
will also decrease conside rably and decrease
b ra ki ng per fo rmance .
Therefore, th e brake flu id must be changed
ev ery
tw o years .
Always use new b rake fluid w hich con­
forms to Fede ra l Motor Vehicle Standa rd " FMVSS
1 16 DOT 4".
The brake fluid rese rvoir can be difficult to reach,
therefo re, we recommend that yo u have the
b rake fluid changed by your authori zed
Audi
dealer .
Your dealer has the cor rect too ls, the
right brake f luid and the know -how to do t his for
you.
A WARNING
- Brake fluid is po isonous. It must be stored
only in the closed orig inal container out of
the reach of children!
- Brake fai lure can result from old or inappro­
pr iate brake fluid . Observe these precau­
t ions:
230
- Use only brake fluid that meets SAE spec i­
ficat io n
J 1703 and conforms to Federal
Motor Vehicle Sta ndard 116 . Always check
with your aut horized Aud i dea ler to make
su re you are using the correct brake fl uid .
The co rrect type of brake f lu id is also ind i­
cated on t he b rake fluid reservoir.
- The brake fl uid must be new. Heavy use of
the b rakes can cause a vapor lock if the
brake fluid is left in t he system too long.
This can se riou sly affec t the efficiency of
the b rakes as well as yo ur sa fety. This
could result in an acc ident .
(D Note
Bra ke fluid will damage the pai nt of you r vehi­
cle.
@ For the sake of the environment
B ecause of the prob lem of prope r disposal of
b rake fluid as well as the spe cial tools re­
q ui red and the necessary ex pert ise, we rec ­
ommend that you have the brake f lu id
cha nged by yo ur autho rize d Aud i dea le r.
Battery
