possib le.
.&, WARNING
-
- If the ml (USA models) ;tlJ (Canada
models) warning light does not go out,
or if it comes on while driving, the ABS
system is not working properly. The vehi­
cle can then be stopped only with the
standard brakes (without ABS). You will
not have the protection ABS provides.
Contact your authorized Aud i dealer as
soon as poss ible.
- If the
1111 (USA models)/ . (Canada
models) brake system indicator light
tu rns on together with the ABS and ESC
indicator ligh ts, the ABS/ESC regu lating
f unction may have failed. F unctions that
stabilize the vehicle are no longer availa­
ble. This could cause the vehicle to
swerve and increase the risk of sliding.
Drive carefully to the nearest authorized
Audi dealer or other qualified workshop and have the malfunction corrected.
:l~ /(® ) Parking brake
The indicator light monitors the parking
brake.
When the parking brake is applied and the ig­
nition is switched on, the. (USA models) /
• (Canada models) indicator light comes on .
The ind icator light must go out when the
parking b rake is released.
BRAKE/CC Dl Brake system
The warning/indicator light flashes if brake
fluid level is low, if there is an
ABS system
ma/function or a parking brake ma/function.
The 1111 (USA models)/ . (Canada models)
light illum inates when the ignition is turned
on.
It goes out after the eng ine has been
started . This indicates that the bra ke warning
l ight is functioning properly.

has been made. If a measurement is not pos ­
sib le, the system cannot respond and wi ll not
react to a vehicle or someth ing else up ahead .
Open road
When the road is clear , the adaptive cru ise
control wo rks like cruise control.
It maintains
a constant target speed specified by the driv­
er.
Driving in traff ic
If a slower vehicle d riving ahead is detected,
the adaptive cru ise contro l decelerates (wi thin
the limits of the system) ¢
page 126, Driver
intervention prompt
and ¢ page 127, System
limitations
to its speed and after adjusting,
tr ies to maintain the set distance from the ve­
h icle ahead. The vehicle may temporarily drive
slower than the set speed while adjusting
¢ .&. in Description on page 115 .
If the vehicle in front accelerates, adaptive
cru ise control also accelerates up to the speed
that you have set.
I f the vehicle ahead slows to a stop, ACC will
slow yo ur vehicle down and to a complete
stop if this is possible w ith in the system's lim­
its and capabilities. ACC will not make an
emergency stop . The text message
ACC off:
manual control! appears in the instrument
cluster display. Once the veh icle stops, you
must dep ress the brake pedal to prevent the
veh icle from mov ing forward or "creeping" .
D epressing the brake pedal turns
off ACC.
When the vehicle ahead accelerates yo u can
reactivate ACC
¢ page 120, as soon as your
vehicle has reached a speed of 1 mph (2 km/
h) .
Situat ion s requiring dri ver int ervention
In some situations you wi ll have to use the
footbrake to s low the vehicle down in order to
k eep a safe distance from vehicle in front of
you or to avo id a rear -end coll is ion. In this sit­
uation, a symbol appears and a warning tone
sounds ¢
page 126 .
Adapti ve crui se control 117
Passing another vehicle
If you move into the passing lane and no ve hi­
cle is detected ahead , the adapt ive cr uise con­
trol acce le rates to the speed you have set and
maintains it.
Overr iding ACC
You can in cr ease yo ur speed at a ny time by
stepping on the accelera tor ped al. A fter you
release the accelerator peda l, the system ad­
justs back down to the speed you prev ious ly
set .
Reducing stopp ing distance
If the radar sensor detects that the d istan ce
to the vehicle a head is less than de fined m ini­
mum distance, the brakes are automatically
prepared fo r emergency braking by the d river .
The brake pads are moved very close to the brake d iscs without actually braking the vehi­
cle. This brake assistant feature reacts more
quick ly to the dr ive r's brak ing, and also works
when adapt ive cruise control is
off . The stop­
ping distance is reduced as a result of th is ad­
vance brake p reparation . Th is fun ction does
not perform any emergency b rak ing mane u­
vers by itse lf; the dr iver mus t always apply the
brakes.
A WARNING
If ACC initiates a braking maneuver, the brake pedal w ill be retracted. Inter ference
with the brake peda l can prevent ACC from
slowing the veh icle down and cause a
crash and serious personal injury.
- Never put anything in the driver's foot­
well or let anyth ing fall into it. An object
in the driver's footwe ll can inte rfe re with
the peda ls and prevent the acce le rator
from being used to override ACC or pre­
vent ACC from being switched
off when
the brake pedal is depressed and also
prevent the vehicle from being slowed
down or stopped .
- Onl y use floor mats that keep the area
aroun d the peda ls free and that can be
securely fastened to the footwell .

Hill descent c ontrol
The hill descent control is sw itched on in off­
road mode. When slowly descending steep
gradients on loose ground or when the axles
are articulated, hi ll descent control provides
assistance by automatically applying the
brakes to keep vehicle speed constant. The ve­
h icle is also rendered easier to steer by selec­
tive distribution of braking force . Hill descent
control intervenes when:
- the accelerator pedal is not pressed,
- the vehicle is travelling less than 12 mph
(20 km/h),
- a steep gradient is detected,
- wheel behavior indicates loose ground or
conditions with poor adhesion (e .g. also ax le
articulation) .
H ill descent control operates both dr iv ing for­
ward and in reverse. Active hill descent con ­
trol is deactivated by pressing the acce lerator
pedal until the conditions for act ivation al­
ready listed are met again.
A WARNING
You should only switch offroad mode on if
your dr iving abilities and road conditions
permit .
- The stabilization function is limited
when offroad mode is switched on. The
dr iv ing wheels could spin and the vehicle
cou ld swe rve, especia lly on slick or slip­
pery road surfaces.
- You should on ly sw itch offroad mode on
when d riving offroad .
(D Tips
Offroad mode cannot be switched on when
adaptive cru ise control* is sw itched on.
Brake system
Operating condit ions and d riving hab it s
The brakes on today's automob iles are st ill
subject to wear, depending largely on operat­
i ng conditions and dr iv ing habits ~& . On
vehicles that are e ither driven mostly in stop-
Int ellig ent technolog y 225
and-go city t raff ic or are driven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often than specif ied in
the
Warranty & Mainten ance boo klet . Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you sho uld use the braking
effect of the engine . This way, you prevent un ­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down cont inuously . Pump the brakes at inter­
vals.
Noises may occur when braking depending on
the speed, braking force and outside condi ­
t ions such as temperature and humid ity .
Mo is ture or ro ad s alt
Under certa in conditions, for example, when
driv ing through water or very heavy ra in, or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads . A
few carefu l brake applications should dry off
the b rake pads or remove any ice coatings.
When you are drivi ng at higher speeds with
the windshield w ipers on, the brake pads wi ll
briefly touch the brake discs in regu la r i nter­
vals so as to improve react ion time when brak­
ing on wet sur faces. You, the drive r, wi ll no t
notice anything .
T he effect iveness of the brakes can be reduced
whe n the vehicle is d riven on a sa lt-cove red
road and the b ra kes are not used. He re too,
you should clean off accumulated sa lt coa ting
from brake discs and pads with a few caref ul
applications of the brake~& .
Corrosion
The re may be a tendency for di rt to b uild up
o n the br ake pads and corros io n to fo rm on
the d iscs i f the car is not driven regularly or
o nly for short trips with litt le use of the
brakes.
If t he brakes a re not used frequently, o r if cor­
ros ion has formed on the discs, it is adv isable
to clean off the pads and d iscs by braking .,.

Faults in the brake system
If you should notice a sudden increase in
brake peda l travel, t hen one of the two bra ke
circ uits may have failed ¢.&. .
Low brak e flu id le vel
Malfunct ions can occur in the brake system if
the brake fluid level is too low . T he brake fluid
l eve l is monitored electronically .
Bra ke boo ster
The brake booster increases the pressure that
you generate w ith the brake pedal. It only op­
erates while the eng ine is running ¢,&. .
Brake lining we ar sta tu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the wheel. If neces­
sary, the wheel may be removed for this in­
spection ¢
page 307, Changing a wheel.
A WARNING
- You should perfo rm bra king maneuve rs
for the p urpose of clean ing the b rake
system on ly if road condit ions permit.
Other road users must not be put at risk -
you may cause an accident!
- Be fore descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too long or too often. This could cause the
brakes to get hot and dimin ish braking
efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Th is may cause the brakes to
overheat, premature wear and inc reased
stopping distance.
- Under certain climat ic and operating
condit ions such as passing through wa­
ter, driving in heavy ra in or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced . In winter, ice can accumu
late on the brake pads, linings,
discs and drums. Carefully app ly brakes
for a test. Brakes will dry and ice coat­ ings w ill be cleaned off after a few care­
ful brake applicat ions .
- 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
b rake discs and pads with a few ca reful
brake applications.
- If you damage the front spoiler, or if you
i n stall a diffe rent spoiler, be s ure the a ir
f low to the front brakes is not obs truct­
ed . Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system .
- Fai lure of one brake circuit will impai r
the braking capability resulting in an in­
creased stopping distance . Avoid driving
the vehicle and have it towed to the near­
est authorized Audi dea ler or qualified
workshop .
- Never let the ve hicle roll to a stop with
the engine shut off.
- If the brake booster is not working, the
brake peda l must be pressed cons idera­
b ly harder to make up for the lack of
booster assistance.
Servotronic - advanced power steering system
The power steering systems uses the power of
the running engine to allow precise steering
with Little effort.
T he advanced Servotronic power steer ing sys ­
tem senses the road speed and electronica lly
adjusts power assistance to provide comforta­
ble and safe steering response exactly match­
ed to the vehicle speed.
Power s teer ing will not work if the engine is
off. As a result, the steering wheel will be hard
to turn.
T he powe r steering fluid level is checked d ur-
ing the sched uled maintenance services . ..,.

The first 1,000 miles
(1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the fir st 600 miles (1,000
kilometers ):
.,. Do not use full throttle.
... Do not d rive at engine speeds that are more
than 2/3 of the max imum permitted RPM.
From 600 to 1,000 miles (1 ,000 to
1,500 kilomete rs):
.,. Speeds can gradually be increased to the
max imum pe rm iss ible road or eng ine speed .
During and after break-in per iod
... Do not rev the eng ine up to high speeds
when it is cold. Th is app lies whether the
transmission is in N (Neutra l) or in gear.
After the brea k-in period
... Do not exceed max imum engine speed un­
der any circumstances.
... Upshift into the next higher gear before
reaching the red area at the end of the tach­
ometer scale¢ page 10.
During the first few hours of driving, the en­
g ine's inter na l friction is higher than later
when all the moving parts have been broken
i n. How well this break- in process is done de­
pends to a conside rable extent on the way the
ve hicle is driven du ring the first 1,000 miles
(1, 500 kilome ters).
(D Note
E xtremely high engi ne speeds are auto­
mat ica lly r educed. However, these rpm
lim its are programmed for a n engine well
r u n- in, not a new eng ine.
{® For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds - upshifting ear ly saves fuel,
reduces no ise and protects the environ­
ment.
, New tires
If your vehicle is runni ng on new tires, drive
part icularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing.
A WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be s ure to remember
this dur ing the fi rst 350 mi les (500 kilo ­
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
braking.
New brake pads
Remember that new brake pads do not have a
full bra king effect dur ing the fi rst 250 m iles
(400 kilomete rs) afte r they a re insta lled.
New brake pads have to be "burnished in" be­
fo re t hey have optima l grab¢
A .
During the break- in period, you should avoid
putting severe loads on the brakes. Severe
l oads include, for example, sudden hard brak­
i ng, in particular at very high speeds or, for
example, on mounta in passes .
A WARNING
New b rake pa ds don't have t he bes t stop­
pi ng power and mus t be "broke n-in " dur­
i ng the in iti al 1 00 to 150 mi les (150 to
20 0 kilometers) of no rma l city driving . You
can compensate for this by pressing the
br ake peda l mo re f irm ly . This also applies

Driving tips
On poor road and offroad, there is always on­
ly one motto : Plan ahead and drive slowly!
P lease obse rve the following when dr iving
away from paved road s:
• Drive only on roads and offroad sections
which match the design of your vehicle and
your abilities as a driver. Never take risks!
• Drive slowly and plan ahead!
• Take in to consideration the
g round cl ea r­
a nc e
of your vehicle .
• Activate the
offroad m ode Q page 223 as
needed.
• Use the
hill desce nt control ~ page 225
when driving down steep sect ions on hills.
Unp aved road s and offroad
Drive slowly on unfamiliar roads and unknown
offroad sections, and look out for unexpected
obstacles (e.g. potho les, rocks , tree stumps ,
etc .).
To prevent the vehicle from bottom ing and
avoid damage to the underbody, you should
d rive st ra ight ac ross severe bumps in the
g round with on ly one s ide of the vehicle so
that on ly two of your wheels cross the bumps. Drive brisk
ly through sandy or marshy offroad
sections and do not stop , if at all possible .
Driving through w ater
Note the following to avoid veh icle damage
when d riving through wate r, for example on
flooded roads :
- The water must not be any higher than the
bottom of the vehicle body.
- Do not dr ive faster than walk ing speed .
Driving on a slope
If you ever find you rself not able to climb a
s lope, do not try to turn around, drive back
down in
r e v erse . Otherwise, you run the r isk
of tipp ing over .
If the veh icle th re at en s to t ip ov er whe n
dr ivin g a cross a slop e, you mus t immediate ­
ly ste er downhill in the dir ection of th e
s lop e.
Do not park your vehicle on steep slopes or
grades .
To reduce the risk of t ipping over, drive on
s lopes in th e direction of the downward s lope
(fall line) -
not c ross wise.
A WARNING
-After driv ing through water, mud, slush,
etc ., the brakes may be s low to take effect
because of wet brake rotors and pads . D ry
the brakes first by brak ing carefully to re­
store t he fu ll braking effect.
(D Note
Vehicle components such as the eng ine,
transmission, suspension or e lectrica l sys­
tem can be severe ly damaged by dr iv ing
th rough water .
(D Tips
-Check the depth of the water before d riv­
ing through it .
- Do not stop the vehicle, drive in reverse or switch the engine off when driving
through water.
