The tether anchors for the rear seating positions are located on the
backside of the rear seatbacks
~ fig. 155.
A tether is a straight or V-shaped strap that attaches the top part of
a child restraint to special anchorage points in the vehicle.
The purpose of the tether is to reduce the forward movement of the child res traint in a crash , in order to help reduce the risk of head
injury that could be caused by striking the vehicle interior.
Forward facing child restraints manufactured after September 1,
1999, are required by U.S. federal regulations to comply with new ..

& WARNING
Improper installation of child restraints will increase the risk of
injury and death in a crash .
• Always follow the instructions provided by the manufacturer of
the child restraint you intend to install in your Audi.
• Improper use of child restraint anchors (including tether
anchors) can lead to injury in a collision . The anchors are designed
to withstand only those loads imposed by correctly fitted child
restraints.
• Never mount two child restraint systems on one LATCH lower
anchor point .
• Never attach two child restraint systems to one tether strap or
tether anchorage .
• Never attach a tether strap to a tie-down hook in the luggage
compartment.
• Never use child restraint tether anchorages to secure safety
belts or other kinds of occupant restraints .
• Never secure or attach any luggage or other items to the LATCH
lower anchorages or to the tether anchors .
• If a tether or other strap is used to attach a child restraint to the
front passenger seat , make sure that it is not so tight , that it
causes the weight -sensing mat to measure more weight than is
actually on the seat .
• The heavier weight registered can make the Advanced Airbag
System work as though an adult were on the seat and deploy the
Advanced Airbag when it must be suppres sed causing serious or
even fatal injury to the child.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on ,
& WARNING (continued)
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer . •

- Depress the spring catch on the hook and release it from
the anchorage.
0 Note
If you leave the child restraint with the tether strap firmly installed
for several days, this could leave a mark on the upholstery on the
seat cushion and backrest in the area where the tether strap was
installed. The upholstery would also be permanently stretched
around the tether strap. This applies especially to leather seats. •
Using tether straps on rearward-facing child
restraints
Currently, few rear-facing child restraint systems come with a tether.
P lease read and heed the child restraint system manufacturer's
instructions carefully to determine how to properly install the
tether.
Controls and equip­ ment Safety first Vehicle operation
& WARNING
A
child in a rearward-facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates -even with an Advanced Airbag System .
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center armrest, or door.
• A tight tether or other strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure
on the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered can make
the system work as though an adult were on the seat and deploy
the Advanced Airbag when it must be suppressed causing serious
or even fatal injury to the child.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
immediately install the rear -facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer. •

actual vehicle behavior. If the two do not match, for example when
th e vehicle begins to skid, ESP brakes the appropriate wheel auto­
matical ly .
The vehicle is stabilized again by the forces acting on the wheel
during braking. With an oversteering vehicle (tendency for the rear
end to skid out of the curve), the brake application is mainly at the
front wheel on the outside of the curve, with an
understeering
vehicle (tendency to run wide in the curve) at the rear wheel on the
inside of the curve or additionally at the other wheels as needed.
This brake application is accompanied by noises.
ESP works in conjunction with ABS=>
page 192. If there is malfunc ­
tion in the ABS, ESP is also inoperative.
Activating
The ESP is automatica lly activated when the engine is started, and
it performs a self-test. As soon as the test is completed, the system
is in normal operating mode. With ASR deactivated, or with ESP/ASR
deactivated, pressing the button=>
page 188, fig. 158 returns the
system to normal operation.
Deactivating
ESP should normally be activated at all times because this ensures
optimum vehicle stability. Only in certain exceptional cases it does
make sense to deactivate Anti-Slip Regulation (ASR) or the Elec­
tronic Stability Program (ESP) by pressing the button =>
page 188,
fig. 158. Both deactivation stages can only be activated from normal
mode .
Deactivating ASR
Tap the switch. Deactivation is indicated by slow flashing of the ESP
lamp in the instrument cluster. In certain situations (e .g. driving
with snow chains, in deep snow or on loose ground, or when
rocking the car free), it may be necessary to deactivate ASR.
Deactivating ESP/ASR
Press the button for more than 3 seconds. Deactivation is indicated
by the ESP lamp in the ins trument cluster staying on permanently.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
This
deactivates the Electronic Stability Program (ESP) in addition to
ASR. No Elec tronic Stability System operation and no Anti -Slip
Regulation is available across the entire speed range; ASR and ESP
are activated only when the brakes are used for the duration of the
braking action and remain active until a stable vehicle condition has
been reached. There is no driving situation which requires ESP to be
deactivated, so this should only be done if the driver's skill and the
traffic situation permit.
& WARNING
• The limits of physics cannot be suspended by ESP. Even in vehi­
cles with ESP. you should always adapt your driving to road and
traffic conditions. This is particularly true on a slippery and wet
road . Do not be tempted by the increased safety provided to take
risks -danger of an accident!
• Please note that when ASR or ESP /ASR is deactivated , the drive
wheels can spin on icy and slippery roads and the vehicle can
break away -danger of skidding!
Electronic differential lock CED1
.)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The elect ronic differential lock (EDU helps the car to start moving,
accelerate and c limb a gradient on surfaces providing poor or
a lmost no grip. Without EDL, this would be difficult, if not impos ­
s ible.
How the system works
The EDL operates automatical ly. It monitors the rotationa l speed of
the drive wheels on an axle with the help of the ABS sensors
=>
page 192. 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 other drive wheel or wheels (all-whee l drivel. 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.
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface
with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move. The wheel less able to transfer
power spins .
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily. The
vehicle remains operational and behaves in the same way as a
vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, 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 risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning. This is
indicated by the ABS warning light=>
page 16. •
Anti-Slip Regulat ion System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP) . When the vehicle starts up and acceler­
ates, the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface.
How the system works
ASR performs automatically, i.e. without the driver's intervention.
With the aid of the ABS sensors=>
page 192, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque is reduced automatically until the tires find enough grip to
lock onto the road surface. The system is active across the entire
speed range.
Th e ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
Activating
The ESP is automatically activated when the engine is started and it
performs a self -test. You can activate a deactivated ASR if required
by pressing the=>
page 188, fig. 158 button. When it is activated,
the message
ESP/ASR on appears briefly in the display.
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=>
page 188, fig . 158. With the ASR deactivated,
the ESP check light comes on, see=>
page 13. The message ASR off
appears in the display as well.
The ASR should normally be activated all the time . Only in certain
exceptional 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 situation 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 J Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when this is not desired.

Braking
Generat information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles 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 autho­
rized Audi dealer more often than specified in the
Warranty & Main­
tenance 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 unnecessary wear on the brake system. If you
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
must use your brakes, do not hold the brakes down continuously.
Pump the
brakes at intervals.
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 time when braking on
wet surfaces. You, the driver, will not notice anything .
Under certain conditions, 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 cautious 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 salt-covered road and the brakes are not used . Likewise,
you clean off accumulated salt coating from brake discs and pads
with a few cautious 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 driven 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
firmly 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~ &.
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is
too low. The brake fluid level is monitored electronically.

Brake lining wear status
Brake lining wear may be checked by visual inspection of the condi­
tion of the brake pads through the openings in the wheel. If neces­ sary, the wheel may be removed for this inspection=> page
270,
"Wheel change" .
L1}. WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road conditions permit. Other
road users must not be put at risk -you may cause an accident!
• Before descending a steep grade, reduce speed and shift trans­
mission 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 diminish braking efficiency.
• Do not "ride the brakes" by resting your foot on the pedal when
you do not intend to brake. This may cause the brakes to overheat,
premature wear and increased stopping distance.
• Under certain climatic and operating conditions such as
passing through water, driving in heavy rain or after washing the
vehicle, the effectiveness of the brakes can be reduced. In winter,
ice can accumulate on the brake pads, linings, discs and drums.
Carefully apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few careful brake applications.
• 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 brake discs and pads with a few
careful brake applications.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes is not obstructed.
Otherwise the brake system could overheat reducing the effective ­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping distance. Avoid driving the
& WARNING (continued)
vehicle and have it towed to the nearest authorized Audi dealer or
qualified workshop. •
Brake booster
The brake booster adds extra braking power.
The brake booster works with vacuum pressure which is created
only when the engine is running=>& .
L1}. WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake booster is not working, for example when towing
your vehicle, or because the brake booster has somehow been
damaged, the brake pedal must be pressed considerably harder to
make up for the lack of booster assistance. •
Func ... ion=ng of Anti-Lock Brake System (ABS)
ABS prevents the wheels from locking up under braking.
The ABS contributes effectively to vehicle control since it prevents
the wheels from locking when the brakes are applied. This means
that the vehicle remains steerable and is less likely to skid.
With ABS you do not need to pump the brake. Just hold the brake
pedal down.
However, do not expect that the ABS shortens braking distance
under
all circumstances . When driving on gravel 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 drive slowly and with great care. .,_

How the ABS system works
An aut omatic check is made whe n a speed of ab out 4 mph (6 km/h)
is reached. When this happens, a pumping noise can be heard.
I f an individua l wheel begins to rotate too slowly in relation to
ve hicle speed and ten ds to lock, the A BS automatical ly reduces
brake pressure to prevent that wheel from locking.
T his auto matic adjust ment p rocess wil l cause a
slight vibration o f
the brake peda l and some noises to alert you that veh ic le speed
must be ada pted to e xisting roa d and traff ic c onditions.
& WARNING
Although the ABS is very effective , always remember that braking
c apability is limited by tire tra ction . Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking e xtra risks .
The ABS cannot overcome the laws of physics.
[ i ) Tips
• I f ABS is not functioning properly, a warning light wil l come on.
See

Brake assistant
The brake a ssi st ant is de sig ned to a chieve th e opti mum
b ra kin g eff ec t.
The brake assistant helps to increase the effective braking power
and thus to ac hieve a s horte r stop ping dis tance. If the drive r
presses the brake pedal very quick ly, the brake assistant automati ­
ca lly b oosts the braki ng force to the maximu m level, up to th e point
where the anti -loc k brake function (A BS) intervenes to stop the
whee ls from loc king. You should then keep the brake pedal pressed

& WARNING
Please remember that the accident risk always increases if you
drive too fast , espe cially in corners or on a slippery road , or if you
follow the vehicle ahead of you too closely . An increased accident
risk cannot be compensated even by the brake assistant , so
always maintain a safe speed. •
