Instruments and warning/indicator lights 19
The ABS warning light and the brake warn­ ing light come on together. The ABS will not
work and you will notice a change in braking response and performance.
Malfunction in the brake system
If the brake warning light <=>page 19 and
the ABS warning illuminate
together there
may be a malfunction in the ABS, and there
may also be a malfunction in the brake system
itself <=>,&. .
In the event of a
malfunction in the brake
system
the warning/indicator light 1111
(USA models);III (Canada models) in the in­
strument cluster flashes. By pressing the
ICHECKI button, you can bring up a driver
message which explains the malfunction in
more detail. Please note
<=>pag e 32.
Malfunction in the electronic differential
lock (EDL)
The EDL works together with the ABS. The
ABS warning light will come on if there is a
malfunction in the EDL system
<=> page 224.
See your authorized Audi dealer as soon as
possible.
.&, WARNING
-
- If the f!B (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 Audi dealer as
soon as possible.
- If the
1111 (USA models)/ . (Canada
models) brake system indicator light
turns on together with the ABS and ESC
indicator lights, the ABS/ESC regulating
function may have failed. Functions 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 indicator light must go out when the
parking brake is released.
BRAKE/CCDl 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 illuminates when the ignition is turned
on.
It goes out after the engine has been
started . This indicates that the brake warning
light is functioning properly.
If the brake warning light does not light up
when the engine is cranking, there may be a malfunction in the electrical system. In this
case, contact your Audi dealer.
If the brake system warning/indicator light
flashes, there is a brake system malfunction .

It maintains
a constant target speed specified by the driv­
er.

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 113 .
If the vehicle in front accelerates, adaptive
cru ise control also accelerates up to the speed
t ha t you have set.
I f the vehicle ahead slows to a stop , ACC will
slow yo ur vehicle down and to a complete
s top 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" .
Depressing the brake pedal turns
off ACC.
When the vehicle ahead accelerates yo u can
reactivate ACC
¢ page 118, 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 ¢

Adapti ve crui se control 115
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 istance
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 control
The hill descent control is switched on in off­
road mode. When slowly descending steep
gradients on loose ground or when the axles
are articulated, h ill 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 trave lling less than 12 mph
(20 km/h),
- a steep gradient is detected,
-wheel behavio r indicates loose ground or
conditions with poor adhesion (e .g. also ax le
articulation) .
H ill descent control operates both driving for ­
ward and in reverse . Active hill descent con­
trol is deactivated by pressing the accelerator
pedal until the conditions for activation al ­
ready listed are met again.
A WARNING
You should only switch offroad mode on if
your dr iving abilities and road cond itions
permit.
- The stabilization function is limited

Brake system
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing conditions and driving habits
c> Li::,. . On
vehicles that are either driven most ly in stop­
and-go city traffic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dealer more often than specified in
the Warranty & Maintenance booklet . Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you should 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 continuously. Pump the brakes at inter­
vals.
Noises may occur when braking depending on
the speed, b raking force and outs ide cond i­
tions such as temperature and humidity.
Moisture or road salt
Under certain conditions, for example, when
driv ing through water or very heavy rain, or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the bra ke pads. A
f ew careful brake applications should dry off
the brake pads or remove any ice coatings.
jll,,

When you are driving at higher speeds wit h
the windshield wipers on, the brake pads will briefly touch the brake d iscs in regular inter­
vals so as to improve reaction t ime when brak­
ing on wet surfaces. You, the driver, will not
notice anything .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered
road and the brakes are not used . Here too,
you should clean
off accumulated salt coat ing
from brake discs and pads with a few careful
applications of the brake ¢ & .
Cor ro sion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for sho rt trips with little use of the
b rakes .
If the brakes are not used frequently, or if cor­ rosion has formed on the discs, it is advisable
to clean
off the pads and discs by b rak ing
fi rm ly a few times from a mode rately h igh
speed ¢.& .
Faults in the brake system
If you should notice a sudden increase in
brake peda l travel, t hen one of the two brake
circu its may have failed¢& .
Low brake flu id le vel
Malfunct ions can occur in the brake system if
the brake fl uid level is too low . T he brake fluid
level is monitored electronically .
Brake booste r
The brake booster increases the pressure t hat
you generate w ith the bra ke pedal. It on ly op­
erates while the eng ine is running¢ &.
Brake lining wear statu s
Brake lining wea r may be c hecked by vis ual in­
spection of the condition of the brake pads
through the openings in the whee l. If neces ­
sary, the whee l may be removed for this in­
spection ¢

A WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Othe r road use rs must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed a nd s hift transmission into a lower
gea r o r l ower dr iving range. Do not ride
the br akes or ho ld t he pedal down too
long o r too often. This could cause the
brakes to get hot and diminish braking
efficiency .
- Do not " ride the brakes" by rest ing you r
foot on the pedal when you do not intend
to brake. This may ca use the brakes to
overheat, premature wear and increased
stopping distance .
- Under certain cl imatic and ope rat ing
conditions such as passing thro ugh wa­
ter , dr iv ing in heavy rain o r after washing
the vehicle , the effectiveness of the
brakes can be reduced . In winte r, ice can
accumu late on the bra ke pads, lin ings,
d iscs a nd drum s. Carefu lly app ly bra ke s
for a test. Brakes w ill dry and ice co at­
ings w ill be cleaned
off after a few care­
fu l brake applicat ions.
- Driving for an exten ded period o f time o n
salt -cove red roads without using your
brakes can a lso affect braking efficiency .
C lean
off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.
- I f you damage the front spoiler, o r if you
install a different spoiler, be sure the air
f low to the front brakes is not obstruct­
ed. Otherw ise the brak e system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one b rake circuit will impai r
the braking capab ility result ing in an in­
creased s topping distance. Avoid driving
the vehicle a nd have it towed to the ne ar­
est a uthorized Audi dea le r or qu alified
wo rkshop.

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
l ater when new pads are installed.

If the vehicle threaten s to tip o ver when
d riv ing across a slope , you mu st imm ediate­
ly steer downhill in the di rection of the
slope.
D o not park your vehicle on steep slopes or
grades .
To reduce the risk of t ipping over, dr ive on
slopes in the d irection o f the downward slope
(fa ll line) -
not cro sswi se.
~ WARNING
After driving through water, m ud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
-
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through water.
{l) Tips
- Check the depth of the wate r before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t h rough water.
- Keep in mind that oncoming vehicles may create waves that raise the water
leve l and make it too deep for your vehi­
cle to drive through safely.
- Avoid dr iving through sa lt water because
i t can cause corrosion.
