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.
Automatic
Select the automatic mode if yo u prefer suspens ion and damping
settings 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 aga in 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 be low about 22 mph (35
km/h).
Comfort
Select the comfort mode if you desire a suspension sett ing with a
special emphasis on comfort. In the standard mode there is
no
lower ing of the suspens ion. Even at high speeds, the veh icle stays at
the same level. Damp ing characteristics with a decided emphasis on
comfort are selected in this mode.
Dynamic
Select the dynam ic mode if you prefer a sporty suspension sett ing. In
this mode, the vehicle is lowered while it is still stationary and sporty
damping characteristics are selected. The warning light
c.::> in the
instrument cluster will come on for a few seconds just to remind you
of the reduced ground clearance.
Controls and equip
ment Safety first
If you switch off the engine while the vehicle is in the dynamic mode
and then switch on the
ignition once again, the
c.::> 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 while it is still stationary and damping
characteristics are adjusted to emphasize comfort.
The 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 automatica lly leaves lift mode and the mode set previously
(standard, automatic, dynamic) is activated again .•

Other things that can affect Advanced
Airbag performance
Chang ing the vehicle's suspension system can change the way that
t h e Advan ced Airbag System pe rforms in a cr ash . For e xamp le, usi ng
tire-rim combinations not app roved by Audi, lowering the vehicle,
c hang ing the stiffness o f th e suspension, incl uding the sp rings,
suspension struts, shock absorbers etc. can change the forces that
are meas ured by the a irbag sensors and sent to the ele ct ronic contro l
unit . Some suspension changes can, fo r exam ple, increase the force
levels measured by the senso rs and make the airbag system deploy in
crashes in which i t would not deploy if the changes had no t been
ma de . Other kinds of changes may reduce the force levels meas ured
by the sensors and p revent the airbag from dep loying when it should.
T he sensors in the safety belt b uckle for the drive r and front

and for the different models of the same kind of child restraint
offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of ch ild
restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typical infants and typical 1 year
old child have been stored in the control unit of the Advanced Airbag
System. When a child restraint is being used on the front passenger
seat with a typical 1 year-old chi ld, the Advanced Airbag System
compares the weight meas ured by the weight sensing mat with the
information stored in the electronic control unit .
The electronic contro l unit a lso registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using the
safety belt as compared to the tension on the belt when it is used to
attach a child restraint to the seat . The sensor below the latch for the
safety belt for the front seat passenger measures the tension on the
belt. The input from this sensor is then used with the weight to
"decide", whether there is a child restraint with a typical 1 year-old
child on the front passenger seat and whether or not the airbag must
be turned off .•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, ma ke sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been ce rtified by its manufacturer for use with an
airbag . Always be sure that the child restraint is properly installed at
one of the rear seating positions. If in exceptional circumstances you
must use it on the front passenger seat, carefully read all of the infor
mation on ch ild safety and Advanced Airbags and heed all of the
app licab le WARNINGS. Make certain that the child restra int is
correctly recognized by the weight-sensing mat inside the front
passenger seat, that the front passenger airbag is turned off and that
the airbag status is always correctly signaled by the
PASSENGER AIR
BAG OFF
light.
Controls and equip ment Safety first Vehicle operation
Many types and models of child restra
ints have been available over
t he years, new models are introduced reg ularly incorpo rating new
and improved designs and older models are taken out of product ion.
Chi ld restraints are not standardized. Child restraints of the same
type typ ically have d ifferent weights and sizes and differe nt 'foot
prints,' the size and shape of the bottom of the child restraint that
sits on the seat, when they are installed on a vehicle seat . These
differences make it virtually impossib le to certify compliance with
t he requirements for advanced airbags with each and every chil d
restra int that has ever been sold in the past or will be sold over the
course of the useful life of your vehicle.
For this reason, the United States Nationa l Highway Traffic Safety

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 246. 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 242, 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 242, 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 244 . 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 246 . 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.
Vehicle care Do-it-yourself service Technical data
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=>& . .,
