Fi g. 106 Disp lay: Se lected speed
• Pull t he lever to posi tion (D ¢ fig . 105 to
switch the sys tem on.
• Drive at the speed you wish to set .
• Press b utton @ to set that speed .
The display
¢fig. 106 will show the set s peed .
The display may v ary depending on t he type o f
display in yo ur vehicle. The indicator
light
[ifj11 )~1~ (US mode l) I. (Canadian mode l)
will also light up in the instrument cluster.
A WARNING
- Always pay attention to traffic even when
the cruise control is switched on . You are
always responsible for your speed and
the distance between yo ur vehicle and
othe r vehicles .
- For safety reasons, the c ruise control
sho uld not be used in the city, in stop­
and -go traff ic, on twist ing roads an d
when ro ad conditions are poo r (such as ice,
fog, gravel, heavy rain and hydro­
plan ing) -risk of accident.
- Turn off the cruise contro l temporarily
when enter ing turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "resting"
your foot on the accelerator pedal causes
the cruise co ntrol not to brake. This is
because the cruise control is over ridden
by the dr ive r's acceleration.
(D Tips
- Veh icles with man ual transmiss ion: You
can attai n the set speed only if the cur­
rently engaged gear allows it and the en­
gine is not stressed . Sh ifting to a highe r
o r low er gea r promptly will a llow the en­
gine to r un smooth ly.
- The cr uise control can not mainta in a
constant speed when driv ing downhi ll.
T he vehi cle w il l accele rate under i ts own
we ight. Dow nshift to a lower ge ar or use
the brakes to slow down .
Changing speed
• Press lever in the 0 or 0 direct io n
¢ page 94, fig. 105 to increase or decrease
your speed.
• Release the lever to save that speed .
Change speed in increments of 1 mph (1 km/
h) by lightly pressing the lever. I f you keep the
lever pressed down, you will alter your speed
in S mph (10 km/h) increments.
You can also press t he accelerator pedal down
to increase your speed, e.g. if you want to
pass someone. The speed you saved earlier
will resume as soon as you release the acceler­
ator pedal.
If, however , you exceed yo ur saved speed by
5 mph (10 km/h) for longer than 5 minutes,
the cru ise control will turn off temporari ly.
T he symbo l will go out but the saved speed
will be reta ined .

Audi magnetic ride
Applies to vehicles: with magnetic ride
Damping can be adjusted to the driver's pref­
erence and it adapts automatically to the cur­
rent driving situation .
Fig. 107 Center console: Sw itch for Aud i magnet ic ride
.,. Press the switch c:> fig. 10 7 to turn sport
sett ing on or off.
Audi magnet ic r ide is an electronically con­
trolled damping system . This chassis system
ass ists the driver by adapting to the particular
s ituat ion through imperceptible control proc­
esses. The
damping provides individual modu­
lation of damping forces. For example, with
damping characteristics set to provide greater
comfort, damping is set somewhat harder for
a brief period on ly as required, when rounding
a curve and when braking.

A WARNING
- Never p lace the selector lever in the R or
P posit ion while the veh icle is moving -
risk of an accident!
- With the engine running, it is necessary
to hold the vehicle with the foot brake in all se lector lever positions (except P and
N), because even at idle speed the trans­
fe r of power is never completely inter­
rupted -the vehicle "creeps". If the vehi­
cle is stationary and the transm ission is
engaged, the engine should never be
speeded up unintentionally (e .g. manual­
ly from under the hood). Otherwise the
veh icle w ill immediately start to move -
sometimes even if the park ing brake is
firmly applied -risk of an accident!
- Before you or other persons open the
hood and work on a running engine, the
selecto r lever must be moved to P and
the park ing brake applied f irmly - risk of
an accident! Follow the warning sticke rs
c::> page 187, Engine compartment.
(D Tips
If you have inadvertently shift ing into N
while the vehicle is moving, you shou ld re­
move you r foot from the accelerator and
wait unt il the engine speed has dropped to
idle before shifting back to Dor S .

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Program (ESP)
Description
ESP helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESP detects
Intelligent technology 161
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G] in the instrument cluster
blinks when ESP is taking action to help you
control the vehicle.
ESP has limitations. It is important to remem­
ber that ESP cannot overcome the laws of
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESP may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered with water,
slush or snow, ESP cannot perform the same
way it would on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESP will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESP cannot always deal as effectively
with difficult driving situations as at lower
speeds. When towing a trailer, ESP is not able
to help you regain control as it would if you
were not tow ing a trailer.
A lways adjust your speed and driving style to
road, traffic; and weather conditions. ESP can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
driver inattention. Instead, ESP improves the
poss ibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection. If you are traveling at a speed that
causes you to run off the road before ESP can
provide any assistance, you may not experi­
ence the benefits of ESP .
•

162 Intelligent technology
ESP includes and/or works together with the
anti-lock brake system (ABS), brake assist sys­
tem and anti-slip regulation (ASR). ESP is
switched on all the time. In certain situations
when you need less tract ion, you ca n sw itch
off ESP by pressing the button [g] _ Be sure to
switch ESP on again when you no longer need l ess traction .
Anti-lock b raking system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even during hard braking. Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the b rake pedal ind icates that
the system is he lp ing you to b ra ke the vehicle.
Br ake a ssist system
The brake assist system can decrease braking
d istance. It increases braking power when the
d river presses the brake pedal quick ly in eme r­
gency situations. You must press and hold the
brake peda l until the si tuation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the fo rce to
the road co ndit io ns. This makes it easier to
start, ac celerate and drive up hills.
Electronic differential loc k (EDL )
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
a ll-wheel d rive*. This funct ion is available up
to abo ut 60 mph (100 km/h).
In extreme cases, EDL automat ically switches
off to help keep the brake on the braked whee l
from ove rheating . EDL w il l switch on aga in au­
tomatically when conditions have returned to
n o rmal.
& WARNING
- ESP, A BS, ASR an d EDL cannot ove rcome
the laws of physics . This is espec ially im ­
portant on slippery or wet roads. If the
systems begin act ing to stab ilize your ve­
hicle, you should immediately cha nge your speed to matc
h the road and t raffic
conditions. Do not let the increased safe­
ty provided by these systems tempt you
to take risks. Do ing so w ill increase the
ris k of a loss of veh icle control , co llision
and serious pe rsonal inj uries .
- Always adapt your speed to road, traffic and weather conditions. The risk of los­
ing control of the vehicle inc reases when
d riving too fast, espec ially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESP, ABS, the brake assist system, EDL an d ASR cannot prevent collisions.
- Always accelera te with special care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve­
h icle control.
(D Tips
- ABS and ASR only work correct ly when
all four wheels are equipped with identi­
cal tires. Diffe rent tire sizes can lead to a
reduction in engine powe r.
- You may hear noises when the systems
descr ibed are working .
- If the indicator light
D] or m (USA
mode ls)/ KC] (Canada models) appears,
t here may be a malfunction~

As soon as the test is completed, the system
is in normal operating mode.
Switching off
E SP should normally be activated at all times
because this ensures optimum vehicle stabil i­
ty. In certa in situations, it might make sense
to a llow some slip . For example:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driving with snow cha ins
Press the
[!I button . The ESP indicator light I)
turns on and S tabil isat ion prog ram off ap­
pears in the d isp lay. ASR deact ivates com­
pletely and the stab ilizat ion effects from the
ESP system are lim ited.
S wi tc hing on
Press the [!I button again. The message S tab i·
li sa tion p rogram on
appears briefly in the dis­
play.
A WARNING
You should only sw itch the ESP off if your
driving ability and the traffic s ituation per­
m it. Please note that when ESP/ASR is de­
act ivated, the drive whee ls can sp in on icy
and slippe ry roads and the vehi cle can
break away - danger of skidding!
(j) Tips
If A udi magnetic ride* is malfunctioning,
the ESP may not switch off or it may
sw itch off automatically.
Braking
General information
What affects braking efficiency?
Operating condit ions and d riving habit s
The brakes on today's automobi les are st ill
subject to wear, depending largely on operat­
ing cond itions and dr iving habits
q .&. . On ve ­
hicles that are either driven mostly in stop­
and -go city traffic or are driven hard, the
brake pads should be checked by your author-
Int ellig ent technolog y 163
ized Audi dea ler more often than specified in
the
W arra nty & M aintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you sho uld use the b raking
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
speed, braking force and outs ide cond it ions
such as temperature and humidity.
Mo isture o r road sal t
If you are driving faster than SO mph (80 km/
h) and the windshield wipers are on, the brake
pads will briefly touch the brake discs in regu­
lar intervals so as to improve react ion time
when brak ing on wet surfaces. You, the driver,
will not not ice anything.
Under certain 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 cautious brake applications should dry off
the b ra ke pads or remove any ice coatings.
The effectiveness of the brakes ca n be reduced
when the vehicle is driven on a salt-cove red
road and the brakes are not used. l ikewise,
you clean off accumulated salt coating from brake d iscs and pads w ith a few cautio us ap­
plications o f the b ra ke
¢ .&, .
Corrosion
T here may be a tendency for di rt to b uild up
o n the brake pads and corros ion to fo rm on
the d iscs if the car is not d riven regu larly or
o nly for short tr ips w ith litt le use of the
brakes.
If the brakes a re not used frequently, o r if cor­
ros ion has formed on the discs, it is adv isable
to clean off t he pads and d iscs by braking
firmly a few times from a moderately high
speed ~.&. . .,.
•
•

However, do not expect that the ABS shortens
braking distance under
all circumstances.
When driving on grave l or on newly fallen
snow on top of icy surfaces, braking distance may be even longer, therefore, under these
circumstances, it is especially important that
you dr ive slowly and with great care .
How th e ABS syste m work s
An automatic check is made when a speed of
about 4 mph (6 km/h) is reached. When this
happens, a pumping noise can be heard .
If an individua l wheel begins to rotate too
slowly in relation to vehicle speed and tends
to lock, the ABS automatically reduces brake
pressure to prevent that wheel from locking.
This automatic adjustment process will cause
a
s light vib ration of the brake pedal and some
noises to alert you that vehicle speed must be
adapted to existing road and traff ic condi­
tions .
A WARNING
Although the ABS is very effective, always
remember that bra king capability is limit­
ed by t ire traction. Always adjust your dr iv­
ing speed according to the road and traffic
conditions . Do not let the extra sa fe ty af ­
forded bytheABStemptyou into taking
extra r isks. The ABS cannot overcome the
laws of physics.
(D Tips
- If ABS is not functioning properly, a
warning light will come on. See
¢ page 18.
- If a fault occurs in the ABS, the EDL is al ­
so not functioning . This is indicated by
the ABS warning light.
Brake assistant
The broke assistant is designed to achieve the
optimum broking effect .
The brake assistan t helps to increase the ef­
fective
b raking power and thus to achieve a
shorter stopping distance . If the driver
Int ellig ent technolog y 165
presses the brake peda l very quick ly, the brake
assistant automatically boosts the braking
force to the max imum level, up to the po int
where the anti-lock brake function (ABS) inter­
venes to stop the whee ls from locking. You
shou ld then keep the brake peda l pressed un ­
