To direct the driver's attention to a pedestrian,
the headlights can flash on the pedestrian three
times in a row when there is a pedestrian warn­
ing.
This occurs at speeds above approximately 35 mph (60 km/h) if you are outside of illuminat­
ed areas and no detected vehicles are shown. The
high beam assistant* controls the marking light*

The following situations may affect the function
of the night vision assist system:
- Poor visibility such as snow, rain, fog or heavy
spray
- Dirty lens on the night vision assist camera
Make sure the night vision assist camera
c::>fig. 127 is not covered by stickers, deposits or
any other obstructions because that can affect
the camera function . For information on clean­
ing , refer to
c::> page 306 .
The pedestrian and wild anima l recogn it ion de­
pends on the temperature difference between
the person/wild anima l and the background . Peo ­
ple/wild animals may not be detected if the dif­
ference is too small. The pedestrian/wild animal marking and the marking light* deactivate at
Assist
temperatures above approximately 77 °F (25 °C)
and during daylight. If the night vision assist im­
age is selected in the instrument cluster display,
then the
II symbol appears at the top on the
right side.
A WARNING
-Pay attention to traffic and the area around
your vehicle when night vision assist is switch­
ed on. The driver is always responsible for as­
sessing the traffic situation.
- Night vision assist can only warn about peo­
ple and wild animals located within the visu­
al range of the infrared camera. The visual
range corresponds to the image in the in­
strument cluster display.
- Night vision assist may not detect people or
wild animals and mark them if
- they are not in an upright position, for ex­
amp le if they are sitting or lying down
and/or
- the silhouette in the display appears in­
complete or interrupted, for example be­
cause the person is partially covered by a
vehicle or an animal by tall grass. This
could increase the risk of an accident.
- Never try to swerve around animals if doing
so will endanger you or other road users, be­
cause this increases the risk of an accident.
(l'} Tips
- Even though the system evaluates the
shape and heat given off by all detected ob­
jects, there are limits to the system . There
may be false warnings.
- For technical reasons, the image pauses in
split second intervals.

Electronic Stabilization
Control (ESC)
Description
The ESC increases driving safety . It reduces the
risk of s lipping and improves driving stabi lity.
ESC detects critical situations such as when the
veh icle is oversteer ing and understeering or the
wheels are spinning. The vehicle is stabilized by
apply ing the brakes or reducing eng ine torque .
When ESC engages, the
Ji] ind icator light blinks
in the inst rument cluste r.
The fo llow ing systems are integrated in the ESC:
Anti -lock b raking system (ABS)
ABS prevents the whee ls from locking when brak­
i n g . The vehicle can sti ll be steered even d uring
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in the
brake pedal indicates that the system is acting to
stabilize the vehicle.
Brake a ssi st sy stem
The brake assist system can dec rease braking dis­
tance. It increases brak ing power when the driver
presses the brake pedal quick ly in emergency sit­
uations . You must press and hold the brake pedal
until the dangerous situat io n is over . In veh icles
w ith adapt ive c ruise control*, the bra ke assis t
system is more sensitive if the distance detected
to the veh icle dr iv ing ahead is too small. On
ve hicles w ith act ivated and functi oni ng night vi­
sion assist*, the brake assist system can respond
more sensit ively if there is a warning .
Anti-slip regulation (ASR)
A SR red uces eng ine power when the d rive wheels
begin s pinning and ad apts the force to the road
conditions. This makes it easier to sta rt, acceler ­
ate and dr ive up hi lls.
Electronic differential lock (EDL )
EDL applies the brakes to a wheel that sta rts
sp inning and t ransfe rs t he d rive powe r to t he
o ther d riving w heels. This f unct ion is not av aila ­
b le at higher speeds .
126
In extreme cases, ED L automat ically switches off
to keep the b rake on the braked whee l from over­
heating. The veh icle is still working correct ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Steering recommendat ion
The E SC he lps to stabili ze the vehicle by changing
the steering torque.
I n veh icles with dyna mic steer ing*, ESC a lso
helps to sta bilize the s teer ing in cr it ica l situa ­
tions.
Selective wheel torque control
Se lective wheel to rque cont rol is used when d riv­
i ng on curves.
The fro nt wheel on the ins ide of the curve or bo th
whee ls on the inside of the curve are braked se­
l ectively as needed. This allows more pre cise d riv­
i ng in cu rves. The applicab le system may no t ac ti­
vate when dr iv ing in we t or snowy condi tio ns.
Automatic post -collision braking system
The "automat ic post-coll is io n braking system"
can help to reduce the risk of sl iding and of addi­
tiona l co llisions after an acc iden t. If the a irbag
c ontro l modu le detects a collision above a cer tain
vehicle speed, the ve hicle is braked by the ESC.
The veh icle does not b rake automatically if:
- the drive r presses the acce lerator pedal, or
- the bra king force generate d by the pressed
brake pedal is greater than the b raking force
that would be in itiated by the system, or
- the ESC, the bra ke system or the vehicle electri­
cal system are not functioning.
A WARNING
- The ESC and its integ rated systems can not
overcome the lim its imposed by natura l
p hys ica l laws. Th is is es pec ially impor tan t
on s lippery or wet roads. If the system s be­
g in a cting to stabilize yo ur vehicle, you
should immedi ately alte r your speed to
match the road and tra ffi c conditions. Do
not let t he i ncreased safety provi ded tempt

0 co .... N ,..... N .... 0 0 :c ' you into taking risks. This could increase
your risk of a co llision.
- Please note the risk of a co llision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre­
vent collisions - there is still a r is k of acci­
dents!
- Press the accelerator pedal carefully whe n
accele rating on even, s lippery surfaces such
as ice and snow. The d rive wheels can spin

Intellig ent Technology
even when these control systems a re insta l­
led and this can affect driving stability and
increase the risk of a collision.
@ Tips
- The ABS and ASR only function correct ly
when a ll four wheels have a simi la r wear
condition. Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine .

Intelligent Technology
Brakes
New brake p ads
New b rake pads do no t achieve the ir full b raking
effect during the firs t 250 mi (400 km) . They
m ust be "broken in" first . The b reak -in period can
be considerably longe r for vehicles with ceram ic
brake rotors* . However, you can compensate for
the slightly reduced braking force by pressing
firm ly on the brake pedal. Avo id heavy braking
during the break-in period .
Wear
Brake pad wear depends largely on the way the
veh icle is driven and on operat ing cond itions.
This is especially true if you are driving frequently
in the c ity and on curves or with 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.
Noises may become more appare nt at lowe r
speeds due to the nature of the materia ls in the
ceramic brake rotors*.
Effect of water and road salt
I n cer tain s ituations, for example a fter driving
through water, in heavy rain, afte r ove rnig ht con ­
densation or after washing your car, the braking
effect can be red uced by moisture or ice on the
brake rotors and b rake pads . The brakes must be
"dr ied" first w ith a few care ful b rake applica­
tions .
At higher speeds and with the windshie ld wipers
turned on, the brake pads press aga inst the brake
rotors for a short amount of time. T his action,
which is no t felt by the driver, happens at regular
i n tervals a nd ensu res a better react ion time for
the bra kes in wet weather.
The braking effect can also be reduced if you are
driving on salted roads a nd you do not apply the
brakes fo r long pe riods of time. The laye r of salt
o n th e brake roto rs and pads mus t be wo rn off
fi rs t when the brakes are app lied.
128
D ue to its s urface, the ce ram ic brake rotor * ab ­
sorbs moisture in ce rtain situations. The refore,
there will tempora rily be less brak ing fo rce than
whe n the brakes are d ry . You can compensate for
th is by press ing the brake pedal harder.
Corrosion
Leav ing the ve hicl e pa rked for long periods of
time , low mileage and avoiding heavy b raking
can contrib ute to corros ion on the b rake roto rs
and to dirty brake pads.
If you usua lly avoid heavy bra king or if there is
cor rosion p resent, occasiona l heavy brak ing at
high speeds is recommended to clean the brake
rotors and pads
c> ,& .
Brake system malfunction
if you no tic e th at the b rake peda l t ravel has sud­
denly

c ir cuit b rake system may have malfunctioned.
D rive to an authorized A udi dealer or authorized
Audi Service Facility immed iate ly to have the
problem corrected . On the way there, drive w ith
reduced sp eed and keep in m ind that you wilt
need a longe r distance to stop and you will need
to press the b rake peda l ha rder.
Low b rake fluid level
When the brake fluid level is low, malfunctions in
the b rake system may occur . The brake fl uid level
i s e lec tronically moni to red.
Brake booster
The brake booster amp lifies the pressure you ap­
ply to the brake pedal. It only wor ks when the en­
gine is running.
A WARNING

was successful.
(D Tips
- If the. or
1;:r- ij ind icator light only stays on
for a short time, you may continue driving.

All wheel drive (quattro)
In all wheel drive, all four wheels are powered .
General information
In a ll wheel drive, the driving power is divided be­
tween a ll four wheels . T his happens automatical ­
ly depending on your driving behavior as well as
t he current road cond itions. Also see
c> page 126, Electronic Stabilization Control
(ESC) .
With the sport differential*, power distri­
bution to the rear whee ls is variable and can be
ad ju sted using the dr ive select
c> page 110.
The all wheel drive concept is designed for h igh
eng ine power. Your ve hicle is exceptionally pow­
erful and has excellent driving characterist ics
both under norma l dr iv ing condit ions and on
snow a nd ice. Always read and fo llow safety pre­
cautions
c> .&. .
Winter tires
By us ing all w heel d rive , yo ur vehicle has good
forward mot ion w ith standa rd t ires in winter con­
d itions . However, in winter we recommend us ing
w in ter o r all season t ires o n all fo ur wheels, be ­
cause this will improve the b raking effect .
Snow chains
If there are snow chai n laws, snow chains must
a lso be used on vehicles with all w heel d rive
c> page 298, Snow chains .
130 Replacing tires
Fo
r vehicles wi th a ll wheel d rive, o nly wheels with
the same ro ll ing circ umfe rence sho uld be used .
Avo id using tires with different tread depths
c> page 290, New tires or wheels .
Offroad vehicle?
You r A udi is not an off road vehicle -there is not
enough ground clearance. For th is reason, avoid
difficult terrain .
A WARNING
- Also, in ve hicles with all wheel drive, adapt
your driving sty le to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking r isks,
because this increases the risk of an acc i­
dent.
- The braking ab ility of your vehicle is limited
to the traction of the wheels . In this way, it
is not different from a two wheel d rive vehi­
cle. Do not be tempted to accelerate to a high speed when the road is s lippery, be ­
c a use th is i ncreases the r is k of an accident.
- Note that on wet st reets, the front wheels
c a n " hydroplane " if driv ing at speed s tha t
are too high. Unlike front wheel drive
vehicles, t he engine does not rev higher sud ­
de nly when the vehicle begins hydroplan ing.
For this reason, adapt yo ur speed to the
road conditions to reduce the risk of an acci­
dent.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventiona l energy sys­
tem is no t drive n for a long t ime, the veh icle bat­
te ry is drained by equ ipment (fo r example, the
i mmob ilizer). In certa in circ umstances, there
could may not be enough energy to start the en ­
gine.
