Hill descent assist brakes a ll four wheels auto­
matically in order to limit speed when d riving ei­
ther forward or reverse on hills with a grade from
approximately 6 to 60%. The wheels will not lock
u p because the ABS remains activated.
When hill descent assist is on, the speed your ve ­
hicle was traveling when it entered the hill is
maintained. It is only possib le to sw itch on the
ass ist when driving slower tha n 37 mph (60 km/
h) . The ass ist beg ins shortly af ter you start dr iv­
i ng and cont inues up to app roxima tely 19 mph
(30 km/h). The d rive r ca n in crease o r de crease

_& WARNING
-Always adapt yo ur speed to the weather,
road and traffic conditions. Do not let the
increased safety provided tempt you into
tak ing risks, because this increases the risk
of an accident.
-
-T he hill descent assist system cannot over­
come the laws of physics. Your driving style
must a lways be adapted to the current road
and traffic conditions.
- Hill descent assist may not be able to hold your vehicle at a constant speed under a ll
condit ions while driving on a hill (for exam­
ple if ground under the veh icle is loose) .
Brakes
New brake p ads
New brake pads do not ach ieve the ir full braking
effect during the first 250 mi (400 km). They
must be "broken
in" first. However, you can com­
pensate for the slightly reduced brak ing fo rce by
p ressing firmly o n the brake pedal. Avoid heavy
b raking during t he b reak-in per iod.
Wear
B rake pad
wear depends largely on the way the
veh icle is driven a nd on operat ing cond itions.
This is especia lly true if you are d riving frequently
in t he c ity and on c urves or wi th a sporty driving
style.
Operating noise
Noises may occur when braking depend ing on the
speed, braking force and outs ide cond itions such
as temperature and humidity .
Wet conditions or road salt
In certain situations, for example after driving
through water, in heavy ra in or after washing
your car, the brak ing effect may be reduced due
to moisture or ice on the brake rotors and brake
Intellig ent Technology
pads. The brakes m ust be "dried" first with a few
carefu l brake app lications.
At higher speeds and w ith the win dshield wipe rs
tu rned on, the brake pads press agains t the b rake
roto rs fo r a short amount of time. This action,
which is not felt by the driver, happens at regu lar
i nterva ls and ensures a better reaction t ime for
the b rakes in wet weather.
T he brak ing effec t can a lso be reduced if yo u are
driving on salted roads and yo u do not app ly the
brakes for long per iods of t ime. The layer of sa lt
on the brake rotors and pads m ust be worn off
first whe n the brakes are applied.
Corrosion
Leaving the vehi cle parked for long periods o f
time, low mileage and avoiding heavy b raking
can contrib ute to corros ion on the brake rotors
and to dirty brake pads.
If you usu a lly avoid heavy bra king or if there is
corrosion present, occasiona l heavy braking at
high speeds is recommended to clean the brake
roto rs and
pads ¢~ -
Brake system malfunction
If you notice that the bra ke pedal trave l has sud­
denly increased, then a brake circuit in the dua l­
ci rcuit brake system may have malfunctioned.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immed iate ly to have the
problem corrected. On the way there, drive w ith
reduced speed and keep in mind t hat you will
need a longer distance to stop and you will need
to press the bra ke ped al ha rder.
Low brake fluid level
When the bra ke fluid level is low, malfunctions in
the brake system may occur. The brake fluid level is elec tronically monitored.
Brake booster
The brake booster ampli fies the p ressure you ap-
ply to the brake pedal.

& WARNING
- Only apply the brakes for the purpose of
cleaning the brake system whe n road and
t raffic conditions perm it . You must not en­
dange r othe r road users . This increases the
risk of an accide nt.
- Never let the vehicle roll while the e ng ine is
stopped because this increases the risk of a n
a cci den t.
([) Note
- Neve r let the brakes " rub" by pressing the
pedal lightly when braki ng is not actually
necessa ry . T his ca uses the bra kes to over­
h ea t an d inc reases br akin g d istance an d
c a uses wear .
- B efo re driv ing downhill a long distance on a
steep hi ll, decre ase your spee d an d se lec t a
l ower gear . This makes use of t he engine
b raking effe ct and re lieves the brakes . If
you nee d to b rake additionally, b rake in in­
tervals and not continuously .
(D Tips
- If the brake booste r is no t working, yo u
must press the brake pedal with much more
fo rce than normal.
- If you retrofit you r vehicle with a front spoil­
er, whee l covers o r similar items, ma ke sure
that the a ir flow to the front whee ls is not
i nte rr u pted. Othe rw ise the brake system
ca n become too hot.

ALL-wheel drive (quattro)
App lies to: vehicles wi th all wheel drive
General information
In all whee l dr ive, the dr iv ing power is dis trib ut-
ed between all fo ur whee ls when needed. This
happens automatically depending on your driving
behavior as we ll as the c urrent road conditions.

Intelligent Technology
Idling current management
The idling c urrent management dec reases the
energy used w hile pa rked. With the engine
sw itched off, it manages the energy distribution
to the different elect rical components . Data from
the battery diagnosis is taken into account for
this .
Depending on the vehicle battery charge level,
e lectrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from
draining and to maintain the starting ability.
Dynamic energy manag em ent
W hil e driving, dynamic energy management dis ­
tr ibutes the appropriate amount of energy to the
electrical equipment. It controls the battery
charge level so that the amount of energy is not
greater than the amount being generated in or­
der to mai nta in a n optimal vehicle battery charge
level.
(D Tips
- Energy management cannot overcome the
l aws of phys ics . Note that the charge leve l
and leng th of the vehicle battery life a re
li mi ted .
- When the starting ability is endanger ed, the
(•) ind icator light turns on~ page 30.
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the vehicle battery
when dr iv ing short d istances, dur ing c ity dr iv ing,
and at cold times of the year . A lot of energy is
used but little is gene rated . It is a lso cri tical
wh en the engine is not runn ing but e lectr ica l
e qui pment is swi tc h ed o n. In this case, energy is
u sed bu t none is ge nera te d.
In s ituatio ns l ike this, energy management will
actively regu late the d ist ribu tion of ene rgy.
Long pe riods without use
If you do not drive your vehicle for several days or
weeks, electrica l equipment is gradually scaled
back or swi tched off . This reduces energy use and
152 ensures
the vehicle will be ab le to s tart a fter long
periods of time. Some conven ience f unctions,
such as interior lig hting or power seat ad just ­
ment, may not be avai lab le under ce rtain circum­
stances. These conven ience functions will be
available again once you switch the ignit ion on
and sta rt the eng ine.
With the engine switched off
The vehicle battery will drain if you use Infotain ­
ment functions such as listening to the radio
whi le the engine is switched off.
If the vehicle's ability to start may be impaired by
the energy use, a message will appear i n the In­
fota inment system display. The message indi­
cates that the system will switc h off automatical­
l y soon. If yo u wou ld like to continue using the
funct io ns, you must s tart the engine .
With the engine running
Although electr ica l energy is generated w hile
driv ing, the veh icle battery can d ra in. This can
happe n if litt le ene rgy is generated but much is
used, and the charge level of the vehicle battery
is not optimal.
To resto re t he ba lance of energy, components
that require large amounts of energy are tempo­ rarily scaled back or sw itched off. Heat ing sys ­
te ms in pa rticula r r equir e a great deal of e nergy .
I f you notice, fo r example, t hat the seat heati ng*
o r r ear window defogger is not wor king, then it
h as been tempor arily reduce d or switched off.
These sys tems are avai lab le aga in as soon as t he
energy supp ly has been restored.
I n add it ion, yo u may notice tha t the idle speed
h as slig htly incre ase d. Tha t is normal and no
ca use for concer n. By in creasing the idling spee d,
the addit io na l required energy will be gene rated
and t he vehicle battery w ill be charged.
