Chassis controls
Four different driving modes can be set by the driver.
The automatic control processes are speed- and time-dependent. For
example, it is not possible to raise the suspension to the lift mode
above certain speeds.

Select the automatic mode if you prefer suspens ion and damping
sett ings emphasizing comfort .
• Lowering : When a speed of about 75 mph (120 km/h) is exceeded
for more than 30 seconds, the vehicle is automatically lowered by
about 0 .6 inch (15 mm) to the dynamic level which is more suitable
for highway speeds. Road holding is optimized as a result of the lower
center of gravity and fuel consumption is reduced as a result of
reduced wind resistance.
• Raising: The vehicle is automatically raised again if the speed falls
below about 44 mph (70 km/h) for a period of 2 minutes. The veh icle
is raised immediately when speed falls below about 22 mph (35
km/h).
Comfort
Select the comfort mode if you desire a suspension setting with a
special emphasis on comfort. In the standard mode there is
no
lowering of the suspension. Even at high speeds, the vehicle stays at
the same level. Damping characteristics with a decided emphasis on
comfort are se lected in this mode .

Dynamic
Select the dynamic mode if you prefer a sporty suspension setting . In
this mode, the vehicle is lowered while it is st ill stationary and sporty
damping characteristics are se lected. The wa rning light
cw in the
instrument cluster will come on for a few seconds just to remind you
of the reduced ground clearance.
If you switch off the engine wh ile the vehicle is in the dynamic mode
and then switch on the ignition once again, the
cw warning light will
also come on again for a few seconds as a reminder.
Lift
Select the lift mode when you have to travel over poor sections of
road (e.g. trails) . In the lift mode, the vehicle is raised by 0.6 inch (15
mm) compared to normal level w hile it is still stationary and damping
characteristics are adjusted to emphasize comfort.
Th e lift mode can be activated only at speeds below 50 mph (80
km/h) . When a speed of about 62 mph (100 km/h) is exceeded, the
system automatically leaves lift mode and the mode set previously
(standard, automatic, dynamic) is activated again.•

The Homelink ® feature can learn the up to three radio
frequency codes for most current transmitters used for
operating garage doors, estate gates, home or outdoor
lighting systems, and other devices.
You must first program the Homelink ® transm itter before you can
use the system=>
page 170, "Programming the Home link® trans­
mitter".
I n order to program the Homelink ® transmitter for devices utilizing
rolling code, a second person on a ladder who can safe ly reach the
garage door opener motor is recommended. It is also necessary to
locate the "learn" button on your garage door opener motor. Refer to
the operating instructions for the opener, as the location and color of
this button may vary by manufacturer.
You can still use the original remote control for the device at any
time.

Safety belts protect
People think it's possible to use the hands to brace the
body in a minor collision . It's simply n ot true!
F ig. 175 Driver is
correct ly re str ain ed in
a s udden b rakin g
m ane uver
Safe ty belts used properly can make a big d ifference. Safe ty belts
help to keep passengers in their seats, gradually reduce energy levels
applied to the body in an accident, an d help prevent the uncon trolled
movement that can cause serious injuries. In add it ion, safety belts
red uce the danger of be ing t hrown ou t of the vehicle .
Safety be lts attach passengers to the car and give them the benefit of
being slowed down more gently or "softly" through the "give" in the
safety belts, crush zones and othe r saf ety features engine ered into
today's vehicles. By "absorb ing" the kinetic energy over a longer
per iod of time , the safety belts m ake the forces on the body more
"tolerable" and less likely to cause injury.
Altho ugh these examples are based on a fronta l collision, safety belts
can also s ubstant ially red uce the risk of injury in other ki nds of
crashes. So, whether you're on a long trip or just going to the corner
sto re, always buckle up and make sure others do, too. Acc ident statis­
tics show that vehicle occupants properly wear ing safety belts have a
lower ris k of bei ng inj ured and a mu ch better cha nce of s urviv ing an
acc ident . Properly using safety belts also greatly increases the ability
of the supp lemen tal air bags to do the ir job in a coll is ion. For this
reason, wearing a safety bel t is lega lly requ ired in most coun tries
including muc h of the Un ited States and Canada. Altho
ugh your Audi is equ ipped with a irbags, you still have to wear
t he safe ty belts provided. Fron t air bags, for ex ample, are a ctiv ate d
only in some frontal collisions . T he front a irbags are not act ivated in
all frontal co llisions, in s ide and rear coll isio ns, in roll overs or in cases
where there is not enough decelerat ion thro ugh impact to the front
of the vehicle . The same goes for the other airbag systems in yo ur
Audi. So, always wea r your safety be lt and make su re everybody in
your vehicle is properly restrained!
Important safety Instructions about safety
belts
Safety b elts must always be correctly positioned across
the strongest bones of your body .
-Always wear safety belts as illustrated and described in
this chapter .
- Make sure that your safety belts are always ready for use and are not damaged .
& WARNING
Not wearing safety belts o r wearing them improperly inc reases
the risk of s eriou s personal injury and death . Safety belts can work
only when u sed correctl y.
• Alway s fasten your safety belts correctly bef ore driving off and
make sure all passengers are corre ctly restrained.
• For ma ximum protection , safety belts must alw ays be posi ­
ti oned properly on the body.
• Never strap more than one person , including small children ,
into any belt .
• Never place a safety belt o ver a ch ild sitting on you r lap .
• Alway s keep feet in the footwell in front of the seat while the
vehicle is being driven.

Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieva l after an accident or crash event. ED R's are
sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by ED R's that were installed 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 w ith
a number of electronic control modu les for various vehicle systems
such as, for example, engine function, emission control, as well as for
the airbags and safety belts.
T hese electronic contro l modules also record vehicle-re lated data
during normal vehicle operation for diagnostic and repair purposes .
Th e recording capacity of the e lectronic control modu les is limited to
data (no sound is recorded) and only a sma ll amount of data is actu­
ally 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 well as restraint system use and performance in the event of a
crash or other condition. Stored data can only be read and down­
loaded with special equipment.
Electronic Stabilization Program
(ESP)
General information
The ESP improves the vehicle stability.
l, I
Fig. 201 Center
console with ESP
switch
ESP is des igned to help you maintain vehicle control in s ituations
where the car approaches the limits of "grip", especia lly when accel­
erat ing and cornering. ESP reduces the risk of skidd ing and imp roves
stability under all road conditions.
Th e system operates across the entire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDL)
and the Anti-Slip Regulation System (ASR) are integrated in the elec­
tronic stabilizatio n pro gram. In addition to the data provided by
these funct ions, the ESP control unit requires additional measure­
ment data provided by high performance sensors. The rotational
speed of the vehicle about its vertical axis, veh icle acceleration in the ...

Intelligent technology
--------------------------------------------------' '----'----
fore-and-aft and lateral directions, the brake pressure and the
steering angle are all measured.
The direction in which the driver wishes to travel is determined with
the aid of the steering angle and vehicle speed and is continually
compared with the actual behavior of the vehicle. If the two do not
match, for example , when the vehicle starts hydroplaning on a wet
road, ESP will automatically brake the appropriate wheel to correct
the problem.
The vehicle is then stabilized by the forces acting on the wheel during
braking. If the vehicle is
oversteering (rear tends to skid out of the
turn), the brakes are mainly applied on the wheel that is on the
outside of the curve. In the case of a vehicle that is
understeering
(tendency to slide out of the curve), the brakes are applied at the rear
wheel that is on the inside of the curve. An acoustic signal indicates
when ESP brake application cuts in =>
&.
The system operates across the entire speed range in combination
with the ABS system =>
page 244. If the Anti-Lock Brake System
(ABS) malfunctions, the ESP will be out of action as well.
Activating
When you turn on the engine, ESP will automatically be activated and
will perform a self-test . As soon as the test is completed, the system
is in normal operating mode.
You can activate a deactivated ESP or deactivated ESP/ ASR if required
by pressing the=>
page 240, fig. 201 button. When they are acti­
vated, the message
ESP/ASR on appears briefly in the display .
Deactivating
The ESP should normally be activated all the time. If necessary , you
can deactivate Anti-Slip Regulation (ASR) or the Electronic Stabiliza­
tion Program (ESP) by pressing the button =>
page 240, fig. 201.
• Deactivating ASR: Tap the but ton . In certain excep tional situa­
tions (e.g. driving with tire chains) , the Anti-Slip Regulation (ASR) can
be deactivated=>
page 242 . The message ASR off appears in the
display as well.
Controls and equip­ ment Safety first Vehicle operation •
Deactivating ESP/ASR
Press the button for more than 3 seconds .
With the ESP/ASR deactivated, the ESP check light comes on, see
=>
page 14. The message ESP switched off appears in the display as
well.
& WARNING
The Electronic Stabilization Program is nevertheless subject to the laws of physics. It is particularly important to pay attention to
this fact on wet and slippery roads. It is therefore important that
you always adapt your driving to the condition of the road and traffic conditions. Do not allow the increased safety provided by
the Electronic Stabilization Program system to lull you into
accepting additional safety risks. •
Electronic differential lock (EDL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differential lock (EDL) helps the car to start moving,
accelerate and climb a gradient on surfaces providing poor or almost
no grip . Without EDL, this would be difficult, if not impossible .
How the system works
The EDL operates automatically . It monitors the rotational speed of
the drive wheels on an axle with the help of the ABS sensors
=>
page 244 . If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground
on
one side),
the spinning wheel is braked, thereby transferring power to
the othe r drive wheel or wheels (all-wheel drive). This is done up to a
speed of about 60 mph (100 km/h) . Noises from the brake system
signal that wheel spin is being controlled.

Driv ing off
When driving off, always be sure to keep road conditions in mind as
you acce lerate. If one d rive w heel spins because it is on a surface with
less grip, gradua lly inc rease the press ure on the accelerator pedal
un til the car sta rts to move .
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads o n this whee l, t he EDL cuts out tem po­
ra rily. The vehicle rema ins operat iona l a nd be haves in the same way
as a ve hicle wit hout EDL.
As soon as the bra ke has coo le d down , ED L swit ches on again au to­
matically.
& WARNING
• When accelerating on slippery surfaces , such as on i ce or snow ,
alway s be careful when depre ssing the accelerator pedal. Even
with the EDL work ing , the drive wheels can spin and reduce your
ability to control your car. Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety ri sks . Always adapt your driving style to the road
conditions and traffic situation.
(I) Tips
If a fa ult occurs i n the ABS, the EDL is also not f unct io ni ng . This is
indic ated by t he A BS war ning ligh t=>
page 17.
Anti-Slip Regulation System (ASR)
The Anti- S lip Re gula tio n Sy stem preven ts the dr iven
w heels from spin ning w hen t he car is accelerating .
General notes
The Anti-S lip Reg ulation Sys tem (AS R) is in tegr ate d in the ele ctroni c
stabilization program (ESP) . When the ve hicle starts up and acceler­
at es, the whee ls are p reven ted from sp inning by adjust ing t he engine
power to match the amount of grip avai lable from the road surface.
How the system works
ASR performs automatically, i.e. witho ut the driver 's intervent ion.

Th e ASR works in conjunction with the ABS. If a malfunction sho uld
occ ur in th e ABS, th e AS R w ill also be out of action.
Activating
The ESP is automatically activated whe n the engine is started and it

deactivation is possible only up to 30 mph (SO km/h) for safety
reas ons. Vehi cles w ith all -w heel drive: the AS R can be deac tivated at
any speed. ..

Intelligent technology
--------------------------------------------------' '----'----
The ASR should normally be activated all the time . Only in certain
except ional situations when some slip is desirable does it make sense
to deactivate the ASR. Examples:
• when driving with tire chains
• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck.
When the abnormal s ituation is over, you should activate the ASR
again .
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[I] Tips
To ensure that the ASR works properly, all four whee ls must be fitted
with ident ical tires . Any differences in rolling radius of the tir es can
cause the system to reduce engine power when this is not desired.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automob iles are still subject to wear ,
depending largely on operating conditions and driving habits=>& .
On vehicles that are either driven mostly in stop-and-go city traffic or
are driven hard, the brake pads should be checked by your authorized
Aud i dealer more often than specified in the
Warranty & Mainte-
Controls and equip­ ment Safety first Vehicle operation nance booklet.
Failure to have your brake pads
inspected can result
in reduced brake performance .
On steep slopes, you should use the brak ing effect of the engine . This
way, you prevent unnecessary wear on the brake system. If you must
use your brakes, do not hold the brakes down continuously. Pump the
brakes at intervals.
Noises may occur when brak ing depending on the speed , braking
force and outside cond it ions such as temperature and humidity.
Moisture or road salt
If you are driving faster than 50 mph (80 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regular intervals so as to improve reaction t ime when braking on wet
surfaces. You, the driver, will not notice anything.
Under certain cond it ions, for example , when driving through water or
very heavy rain, or even after washing your vehicle, the braking effect
can be reduced due to moisture (or in freezing conditions ice) on the
brake pads. A few careful brake applications should dry off the brake
pads or remove any ice coatings.
The effectiveness of the brakes can be reduced when the vehicle is driven on a sa lt-covered road and the brakes are not used. Here too,
you should clean off accumulated salt coating from brake discs and
pads with a few careful applications of the brake=>& .
Corrosion
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 short trips with little use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
fi rm ly a few times from a moderately high speed=>& .
Faults in the brake system
If you should notice a sudden increase in brake pedal travel, then one
of the two brake circuits may have failed=>& . .,
