Why safety belts?
Frontal co11isions and the law of physics
Front al crashes create very strong forces for pe ople rid ing
in vehicles.
Fi g. 185 U nbel ted
o cc up ants in a ve hicle
he ading for a wa ll
F ig . 18 6 The vehi cle
c ras hes in to the wa ll
The physical principles are simple. Both the vehicle and the passen­
gers possess energy which varies with vehicle speed and body
we ight. Engineers cal l this energy "kinetic energy ."
T he higher the speed of the vehicle and the greater the vehic le's
we ight, the more energy that has to be "absorbed" in the crash .
Vehicle speed is the most significan t factor. If the speed doubles
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 times! .,

Safety belts protect
People think it's possible to use the hands to brace the
body in a minor collision. It's simply not true!
Fi g. 189 Driver is
co rrec tly res trai ned in
a sudden braking
m an euver
Safety belts used properly can make a big difference . Safety belts
help to keep passengers in their seats, gradually reduce energy
levels applied to the body in an accident , and help prevent the
uncontrolled
movement that can cause serious injuries. In addition,
safety be lts reduce the danger of being thrown out of the vehic le.
Safety belts attach passengers to the car and g ive them the benefit
of being s lowed down more gently or "softly" through the "give" in
the safety belts, crush zones and other safety features engineered
into today's vehicles . By "absorbing" the kinetic energy
over a
longer period of time, the safety belts make the forces on the body
more "tolerable" and less like ly to cause injury.
Although these examples are based on a frontal collision , safety
belts can also substantially reduce the risk of injury in other kinds
of crashes. So, whether you're on a long trip or just going to the
corner store, always buckle up and make sure others do, too. Acci ­
dent statistics show that vehicle occupants proper ly wearing safety
bel ts have a lower risk of being injured and a much better chance o f
surviving an accident . Proper ly using safety belts also greatly
increases the abi lity of the supplementa l airbags to do their job in a
collision. For this reason, wearing a safety be lt is legally required in
most countries including much of the United States and Canada . Although your Audi is equipped with airbags, you sti
ll have to wear
the safety belts provided . Fron t airbags, for example, are activated
only in some frontal collisions . T he front airbags are not activated in
all frontal col lisions, in side and rear collisions, in roll overs or in
cases where there is not enough dece leration through impact to the
front of the vehicle . The same goes for the other airbag systems in
your Audi . So, always wear your safety belt and make sure
every ­
body in your vehic le is properly restrained! •
Important safety instructions about safety
belts
Safety belts must always be correctly positioned across
t he strongest bones of your body.
Always wear safety belts as illustrated and described in
this chapter.
Make sure tha t your safe ty belts are a lways ready for use

The system operates across the entire speed range in combination
with the ABS system. If the Anti -Lock Brake System (ABS) ma lfunc­
tions, the ESP wil l also shut down .
How the system works
The Anti -Lock Brake System (ABS), Electronic Differential Lock (EDU
and the Anti -Slip Regulation System (ASR) are integrated in the elec­
tronic stabilization program. In addition to the data provided by
th ese functions, the ESP control unit requires additional measure ­
ment data provided by high performance sensors . The rotational
speed of the vehicle about its vertica l axis, vehicle acceleration in
the 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 continua lly
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehicle starts hydrop laning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the prob lem.
The vehicle is then stabi lized by the forces acting on the whee l
during braking. If the vehicle is
oversteering (the vehicle turns too
sharply and the rear wheels slide toward th e ou tside of a curve), the
brakes are main ly app lied on the wheel that is on the outside of the
curve . In the case of a vehicle that is
understeering (the vehicle does
not turn sharply enough and pushes out of a curve), the brakes are
applied as needed on the wheel that is on the inside of the curve or
additional ly on the other wheels. An acoustic signal indicates when
ESP brake app lication cuts in=>&.
T he system operates across the entire speed range in combination
with the ABS system =>
page 238. 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 automatica lly be activated
and will perform a se lf-test. As soon as the test is comp leted, the
system is in norma l operating mode.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
You
can activate a deactivated ESP or deactivated ESP/ASR if
required by pressing the::::>
page 234, fig. 215 ::::> page 234, fig. 214
button . When they are activated, the message
ESP /ASR on appears
briefly in the display .
Deactivating
The ESP should normally be activated al l the time. If necessary, you
can deactivate Anti -Slip Regu lation (ASR) or the Electronic Stabiliza­
tion Program (ESP) by pressing the button=>
page 234, fig. 215.
• Deactivating ASR: Tap the button . In certain exceptional situa­
tions (e .g. driving with tire chains), the Anti-Slip Regulation (ASR)
can be deactivated =>
page 236. The message ASR off appears in the
display as we ll.
• Deact ivating ESP/ASR Press the button for more than 3 seconds.
With the ESP/ASR deactivated, the indicator light comes on, see
=>
page 13. The message ESP switched off appears in the disp lay as
we ll.
& 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 Elec­
tronic 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 (EDU helps the car to start moving,
acc elerate and c limb a gradient on surfaces providing poor or
Vehicle care Do-it-yourself service Technical data

ll}JI Intelligent technology
---""'------------ ....::....:...:~---------------------------
almost no grip. Without EDL, this would be difficult, if not impos­
sible.
How the system works
The EDL operates automatically. It monitors the rotational speed of
wheels with the help of the ABS sensors=:,
page 238 . If a noticeable
slip is detected at the wheels (e.g. on slippery ground on one side),
the spinning wheels are braked and power is transferred to the
other wheels. 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, apply
plenty of throttle until the car starts to move.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads on this wheel, the EDL cuts out tempo­ rarily. 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 15. •
Anti-Slip Regulation 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 238, ASR monitors the
speed of the driven wheels. If the wheels start to spin, 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.
The 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 234, fig. 215 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 234, fig. 215. 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 can be deactivated at any
speed.
The ASR should normally be activated all the time . Only in certain
exceptional situations when some s lip 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 ] Tips
To ensure that the ASR works properly, al l four wheels must be fitted
with identical tires. Any differences in rol ling radius of the tires 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 automobiles are still subject to wear,
depending large ly 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-
Intelligent technology
rized Audi dealer more often than specified in the Warranty & Main­
tenance booklet.
Fai lure to have your brake pads inspected can
resu lt in reduced brake performance .
On steep slopes, you shou ld use the braking 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 continuous ly.
Pump the brakes at intervals.
Moisture or road salt
If you are driving faster than 31 mph (50 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, wil l not notice anything.
Under certain conditions, for example, when driving th rough 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 ef fectiveness 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 sa lt coating from brake discs and
pads with a few carefu l 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 drive n regularly or
only for short trips with litt le use of the brakes .
I f 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
firm ly a few times from a moderately high speed:::::>& .
Faults in the brake system
If you shou ld notice a sudden increase in brake pedal travel, then
one of the two brake circuits may have failed:::::>&. ..,

Low brake fluid level
Ma lfu ncti ons can occ ur in th e brake system if the bra ke flu id leve l is
too low. The brake fluid leve l is monitored e lectronically.
Brake lining wear status Bra ke lining wear may be checked by visual inspection of the condi ­
t ion of the brake pa ds through the o pen in g s in t he wheel. If neces ­
sary, the wheel may be removed for this inspection=>
page 312,
" C hanging a whee l" .
& WARNING
• You should perform braking maneuver s for the purpose of
cleaning the brake system only if road cond itions permit . Other
road u sers must not be put at risk -you may cause an accident !
• Before des cending a steep grade , reduce speed and shift trans ­
mission into a lower gear or lower driving range. Do not ride the
brake s or hold the pedal down too long or too often . This could
c ause 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, p rem ature wear and in creased stopping distance .
• Under certain climatic and operating conditions such as
passing through water , driv ing 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 afte r a few careful b rake appli cations .
• Driving for an extended period of time on salt -covered roads
without using your brakes can also affe ct braking effic ien cy. 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 obstru cted .
Otherwise the brake system could overheat reducing the effe ctive­
ness of the entire brake system .
& WARNING (continued )
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping distance . Avoid driv ing the
vehicle and have it towed to the nearest authorized Audi dealer or
qu alified workshop. •
Brake booster
The bra ke boos ter adds e xtra bra king pow er.
Th e brake boost er wo rks wit h vacuum p ressu re wh ich is created
only when the engine is running=>& .
& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake booster is not working , for e xample 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 . •
Functioning of Anti-Lock Brake System (ABS}
A BS p revents t he wheels from lockin g up unde r braking.
The ABS co ntrib utes effectively to ve hic le c ont ro l since it preven ts
the whee ls from locking when the bra kes are app lied. Th is means
that the vehicle remains stee rable and is less l ikely to skid .
With ABS you do not need to
pump the brake. Just hold the brake
pedal down .
Ho wever , do not e xpect the AB S to sho rten braking d istance under
all circumstances. When driving o n grave l or on newly fallen snow
o n t op of icy su rfaces, b raking distance may be even lo nger, there ­
f ore, unde r these circumsta nces, it is especially impo rtan t th at you
drive slow ly and with great ca re. ._

• Be aware of the different than usual steering response and
adjust your steering force accordingly.
• Have the problem checked and set right by an Audi dealer as
soon as possible.
[ i] Tips
• When the engine is running, never hold the steering wheel
turned all the way to the right or to the left for longer than 15
seconds. The power steering pump will overheat the hydraulic fluid
if you keep holding the steering wheel turned all the way. This is
likely to damage the power steering system.
• If the power steering system should fail en tirely, or if the engine
is not running (for example, while being towed), you will still be able
to steer the vehicle . However,
considerably more effort will be
required to do so.
• If the power steering system should have a leak, or is not func­
tioning properly, contact your authorized Audi dealer immediately.
• The power steering system requires a specially formulated
hydraulic fluid. The power steering reservoir is the one located
farthest to the rear on the left side of the engine compartment
=>
page 272. The correct fluid level in the reservoir is important for
proper functioning of the power steering .•
Driving with your quattro®
With all wheel drive, all four wheels are driven.
General information
With all wheel drive, power is distributed to all four wheels. This
happens automatically depending on your driving style and the
road conditions at the time. See also=>
page 235, "Electronic differ­
ential lock (EDU".
The all wheel drive concept is designed for high engine power. Your
vehicle is exceptionally powerful and has excellent driving charac -teristics both under normal driving conditions and on snow and ice.
Always read and
follow safety precautions =>& .
Winter tires
When driving in the winter, your vehicle with all wheel drive has an
advantage, even with regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-season tires) for improved
driveability and braking : these tires must be mounted on
all four
wheels.
See also => page 304, "Winter tires".
Tire chains
Where tire chains are mandatory on certain roads, this normally
also applies to vehicles with all wheel drive =>
page 305, "Snow
chains".
Replacing vvheels/tires
Vehicles with all wheel drive must always have tires of the same
si ze . Also avoid tires with different tread depths. For details see
page =>
page 299, "New tires and replacing tires and wheels".
Off-Road driving?
Your Audi does not have enough ground clearance to be used as an
off-road vehicle. It is therefore best to avoid rough tracks and
uneven terrain as much as possible. Also refer to=>
page 244.
& WARNING
Always adjust your driving to road and traffic conditions. Do not
let the extra safety afforded by all wheel drive tempt you into
taking extra risks.
• Although the all wheel drive is very effective, always remember
that braking capacity is limited by tire traction. You should there ­
fore not drive at excessive speeds on icy or slippery road surfaces.
• On wet road surfaces, be careful not to drive too fast because
the front wheels could begin to slide on top of the water (aqua­
planing). If this should occur, you will have no warning from a
sudden increase in engine speed as with a front-wheel drive
