Why safety belts?
Frontal collisions and the Law of physics
Frontal crashes c reate very s trong f orces for people
riding in vehicles.

c ra she s into the wall
The p hys ica l pr inc iples are simple. Both the vehicle and the passen ­
gers possess energy wh ich var ies wit h veh icle speed and body weight.
Enginee rs call th is ene rgy "kinetic energy."
The higher the speed of the veh icle and the greater the vehicle's
we igh t, the more e ne rgy tha t has to be "abso rbed" in t he crash.
Vehicle speed is the most sign ificant factor.
If the speed doubles
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 t imes!
Because the passenge rs of this vehicle a re not using safety belts
=> fig. 168, they w ill keep moving at the same speed the vehicle was
moving j ust before the crash, unt il some thing stops them· here, the
wall => fig . 169 .
Th e same principles apply to people sitting in a vehi cle that is
involved in a frontal collision . Even at city speeds of 20 to 30 mph (30
to 50 km/h), the forces acting on the body ca n reach one ton (2,000
lbs . or 1,000 kg) or mo re . At greate r speeds, these forces are eve n
higher.
People who do not use safety bel ts are also not at ta ched to their
vehicle . In a frontal collision they will also keep moving forward at
t he speed the ir veh icle w as t ravelling just befo re the crash. O f course,
the laws of p hys ics don 't just apply to frontal collis ions, they deter ­
mine wha t happens in a ll kinds of accidents and collisions .•

The system operates across the entire speed range in combination
w ith the ABS sys tem. If the A nti-L o ck Brak e System (A BS) mal fun c­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Elect ronic D ifferential Lock (EDL)
and the Anti-Slip Regul ation System (AS R) are in teg rated in the e lec ­
tronic stab ilizat ion program . In addition to the data prov ided by
th ese fun ctions, the ESP control unit re quires addi tional meas ure ­
ment data provided by hig h pe rformance senso rs . The ro tat ional
speed of the vehicle about its vertical axis, veh icle acceleration in the
fore-and-a ft and lateral d irect ions, the brake pressure , a nd the
steerin g ang le are all measured .
Th e d irec tion in whi ch the driver w ishes to tra ve l is d ete rm ined wi th
the a id of the steering a ngle and ve hicle speed and is con tinually
c omp ared wi th the a ctu al b ehavior o f the ve hicl e. If t he two do no t
match, for example, when the vehicle starts hydroplani ng on a wet
roa d, E SP w ill automatica lly bra ke the approp riate whee l to correct
the problem.
Th e ve hicle is t hen stab ilized by the fo rces acting on the whee l during
bra king .
If the ve hicl e is oversteering (the vehicle tu rns too s harp ly
and the rear whee ls slide toward the outside of a curve), the brakes
a re mainly a pplied on the whee l tha t is o n the o uts ide of t he curve. In
the case of a vehicle that is
understeering (the vehicle does not turn
shar ply enough and push es out o f a curve), the b rakes are ap plied as
needed on the whee l th at is on the inside of the curve or additionally
on the ot her wheels . An acoustic s ignal indicates w hen ESP bra ke
applica tion cuts in=> &.
T he system operates across the entire speed range in combination

& WARNING
The Electronic Stabilization Program is nevertheless subje ct 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 elec tronic differen tial lock monitors the rotational
speed of the drive wheels.
G en era l not es
The electronic differentia l lock (EDL) helps the ca r to sta rt moving,
accelerate and climb a gradient on surfaces provid ing poor or almost
no grip . W ithout ED L, this would be d iff icu lt, if not impossible.
How the sy stem works
The EDL operates automatically. It mo nitors the rota tional speed of
wheels with the help of the ABS sensors~
page 241. If a not iceab le
slip is detected at the wheels (e.g . on slippery g round on one side),
the spinn ing 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).
No ises from the brake system signal that wheel sp in is being
controlled.
Driv ing off
When d riving off, always be s ure 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.
O verheating of bra kes
To prevent the disc b rake of the bra ked wheel from ove rhea ting if
subjected to excessive loads on this wheel, the EDL cuts out tempo­
ra rily. The vehicle remains operat io nal and be haves in the same way
as a veh icle without EDL.
As soon as the brake has coo led down, EDL switches on again auto ­
matically.
& WARNING
• When ac ce le rating on s lippery surfa ce s, su ch as on ic e or snow,
alwa ys be ca reful when depre ssing the accele rator pedal. Even
& W ARNING (continue d)
with the EDL working , the dri ve wheels c an spin and reduce your
ability to contr ol your car . Ri sk of cra sh!
• The inc reased s afety afforded by E DL does not me an that you
can take safety ri sks. Alwa ys adapt your d rivin g style to the r oad
conditions and t raffic situation .
[ i ] Tips
If a fau lt occurs in the ABS, the EDL is also not funct ion ing. This is
ind ic a ted by the ABS warn ing light ~
page 17. •
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-Sl ip Regu lation System (ASR) is integrated in the electronic
stabiliza tion prog ram ( ESP) . When the ve hicle s tarts up and acceler­
ates, the wheels are prevented from sp inning by adjusting the engine
powe r to match the amount of g rip available from the road surface .
How the system works
ASR performs au toma tic a lly, i.e. witho ut the dr ive r's intervent ion.
With the aid of the ABS sensors~
page 241, ASR monitors the speed
of the driven wheels. If the whee ls start to spi n, eng ine torq ue is
reduced automatically unti l the tires find enough grip to lock onto
t he road s urface . The system is active across the en tire spee d range.
Th e ASR works in con ju nction with the ABS .
If a malfunction shou ld
occur in the ABS, the ASR wi ll also be out of action.
Act ivating
T he ESP is automatica lly activated when the engine is started and it
performs a self-test . You can act ivate a deact ivated ASR if required by _,,

Intelligent technology
--------------------------------------------------' '----'----
pressing the=> page 236, fig. 198 button. When it is activated, the
message
ESP/ASR on appears briefly in the display.
Deactivating
You can deactivate the ASR if req uired by press ing the button (for less
than 3 seconds) =>
page 236, fig. 198. With the ASR deactivated, the
ESP check light comes on, see=>
page 15. 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 slip is desirable does it make sense
to deactivate the ASR. Examp les:
• 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 sho uld 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 tir es . Any differences in rolling radius of the tir es can
cause the system to reduce eng ine 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 la rgely on ope rating 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
Audi dealer more often than specified in the
Warranty & Mainte ­
nance booklet.
Failure to have your b rake 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 must
use your brakes, do not hold the brakes down continuously. Pump the
brakes at intervals.
Noises may occur when b rak ing depending on the speed, braking
force and outside cond itions such as temperatu re and humid ity.
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
regula r interva ls so as to improve reaction time when braking on wet
surfaces. You, the driver, will not not ice anything.
Under certain condit ions, for example, when driving through water or
very heavy rai n, or even after washing your vehicle, the braking effect
can be reduced due to moisture (o r in free zing conditions ice) on the
bra ke pads. A few careful brake applications should dry off the brake
pads or remove any ice coatings.
Th e effectiveness of the brakes can be reduced when the vehicle is
dr iven on a salt-covered road and the brakes are not used. H ere too,
you should clean off accumu lated salt coating from brake discs and
pads with a few careful applications of the brake=>&,.
Vehicle care Do-it-yourself service Technical data

Intelligent technology
'-------------------------------------------------
Corrosion
T he re may be a te ndency fo r d irt to build u p on the bra ke pads and
co rrosion to form on the d iscs if the car is not dr iven reg ularly o r only
for short trips with litt le use of the bra kes .
If the brakes a re not used freq uen tly, or if co rrosion has formed o n
the discs, it is advisable to clean off the pads and discs by braking
fir mly a few times from a mode rat ely h igh spee d~ & .
Faults in the brake system
If yo u sh ou ld noti ce a sudden increase in b rake peda l trave l, then one
of the two brake circu its may have failed~& .
Low brake fluid level
Ma lfunctions can occ ur in t he brake system if the brake fluid level is
t oo low. The bra ke f lu id level is moni tore d elec tron ically.
Brake lin ing wear status
Brake lin ing wear may be checked by v isua l inspect ion of the condi­
tion of the brake pads throu gh the open ings in the whee l.
If neces­
sary, the whe el may be removed fo r thi s insp ection~
page 3 16,
"Changing a w hee l".
& 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 cau se 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 condition s such as
passing through water , driving in heavy rain or after washing the
& WARNING (co ntinued )
vehicle, the effectiveness of the brakes can be reduced . In winter,
ice can ac cumulate on the brake pads, linings, dis cs and drums.
Carefully apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few careful brake appli cations.
• Driving for an extended period of time on salt-covered roads
without u sing your brakes can also affect braking efficiency . Clean
off accumulated salt coating from b rake discs and pads with a few
careful brake applic ations.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes i s 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 di stance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified workshop.

& 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 mu st be pressed considerably harder to
make up for the lack of booster assistance. •
