Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles.
F ig. 11 8 Unbelted occ upants in a ve hicle h eading for a
wall
Fig. 1 19 Th e vehicle c rash es into t he wall
The physical principles are simple. Both the
vehicle and the passengers possess energy
which varies w ith veh icle speed and body
weight . Engineers call this energy "kinetic en­
e rgy ."
T he higher the speed of the vehicle and the
g reater the vehicle's we ight, the more energy
that has to be "absorbed" in the 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 passengers of this veh icle are not
using safety belts
c::;, fig. 118, they w ill keep
mov ing at the same speed the vehicle was
mov ing just before the c rash, unt il something
stops them - here, the wall ¢
fig. 119 .
The same principles apply to people sitting in
a vehicle that is involved in a frontal collision .
Even at c ity speeds of 20 to 30 mph (30 to
50 km/h), the forces acting on the body can
reach one ton (2,000 lbs , or 1,000 kg) or
more . At greater speeds, these forces are even
highe r.
Peop le who do not use safety belts are also
not attached to their vehicle. In a frontal colli­
s io n they will also keep moving forward at the
speed their veh icle was t ravell ing just before
the crash . Of co urse, the laws of physics don't
just app ly to frontal collisions, they determine
what happens i n all kinds of acc idents and col­
lisions .
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!

occupant will slam violently into the steering
wheel, instrument panel, w indshield , or what­
ever else is in the way
c::> fig. 120. This impact
with the vehicle interior has all the energy
they had just before the crash.
Never rely on airbags alone for protection.
Even when they deploy, airbags provide only
additional protection. Airbags are not sup­
posed to deploy in all kinds of accidents. Al­
though your Audi is equipped with airbags, all
vehicle occupants, including the driver, must
wear safety belts correctly in order to mini­ mize the risk of severe injury or death in a
crash.
Remember too, that airbags will deploy only
once and that your safety belts are always
there to offer protection in those accidents in
which airbags are not supposed to deploy or
when they have already deployed. Unbelted
occupants can also be thrown out of the vehi­
cle where even more severe or fatal injur ies
can occur.
It is also important for the rear passengers to
wear safety belts correctly. Unbelted passen­
gers in the rear seats endanger not only them­
selves but also the driver and other passen­
gers
c::> fig. 121. In a frontal collision they will
be thrown forward violently, where they can
hit and injure the driver and/or front seat pas ­
senger.
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!

Safety belts 13 7
Safety belts used properly can make a big dif­
ference. 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 belts
reduce the danger of being thrown out of the
vehicle .
Safety belts 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 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
likely to cause injury.
Although these examples are based on a fron­
tal collision, safety belts can also su bsta ntia l­
ly 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. Accident sta­
tistics show that vehicle occupants properly
wearing safety belts have a lower risk of being
injured and a much better chance of surviving
an accident. Properly using safety belts also
greatly increases the ability of the supplemen­
tal airbags to do their job in a collision . For
this reason, wearing a safety belt is legally re­
quired in most countries including much of
the United States and Canada.
Although your Audi is equipped with airbags,
you still have to wear the safety belts provid­
ed. Front airbags, for example, are activated
only in some frontal collisions. The front air­
bags are not activated in all frontal collisions,
in side and rear collisions, in roll overs or in
cases where there is not enough deceleration
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 everybody in your vehicle is
properly restrained!

Information about
data recorded by
vehicle control
modules
Your vehicle is not equipped with a crash data
recorder. This device is installed by some vehi­
cle manufacturers to record data about crash­
es so that it can be analy zed later . Crash data
recorders are also called "Event Data Record­
ers ( EDR)" .
In some legal jurisdictions, it is not permitted
to access or download data recorded by pre­
installed crash data recorders in order to eval­
uate a crash without clear consent of the vehi ­
cle owner .
Your vehicle is not equipped with a crash data recorder. However it does contain a variety of
electronic control modules for various vehicle
systems such as engine function, exhaust
treatment or airbags and safety belts .
These electronic control modules record vehi­ cle data during normal driving for diagnosis
and repair purposes . The recording capability
of the electronic control modules is limited to
data only- no sound is recorded.
If the control
module detects a system ma lfunction or other
change in status, a very limited amount of da ­
ta is recorded for an extremely small period of
time . Data that is recorded in such a case may
include vehicle speed, d riving direction, the
load on the brakes and head restraints and
performance in the event of an acciden t or
other change in status . The stored data can
only be read or downloaded with special devi­
ces.
Electronic stabilization
control (ESC)
Description
The Electronic Stabilization Control (ESC) con­
tr ibutes to driver safety. It reduces the risk of
slipp ing and improves driving stability. ESC
Smart Technolog y 189
detects critical situations such as the vehicle
oversteering and understeering or the wheels
are spinning . The vehicle is stabilized by ap­
plying the brakes or reducing engine torque.
Once the ESC is activated, the indicator light
m blinks in the instrument cluster .
The following systems are integrated in the
ESC:
Anti-lock braking system (ABS )
ABS prevents the whee ls from locking when
braking. The vehicle can still be steered even
during hard braking. Apply steady pressure to
the brake pedal. Do not pump the pedal. A
pulsing in the brake peda l indicates that the
system is acting to stabilize the vehicle.
Brake assi st sys tem
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the brake pedal until the dangerous situation is
over . In vehicles with adaptive cruise control*,
the brake assist system is more sensit ive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin spinning and adapts the force to
the road conditions . This makes it easier to
start , accelerate and dr ive up inclines .
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equ ipped with
all wheel drive*). This function is not available
at higher speeds .
In extreme cases, EDL automatically switches
off to keep the brake on the braked wheel
from overheating . The vehicle is still working
correctly. EDL will switch on aga in automat i­
cally when cond itions have returned to nor-
mal. .,..

Steering r ecommendat ion
The ESC helps to stabilize the vehi cle by
changing the steering torque.
Select ive wh eel torqu e co ntrol
Select ive wheel torque control is used when
driving on curves . The front wheel on the in ­
side of the curve or both wheels on the inside
of the curve are braked selective ly as needed.
Th is a llows more precise driv ing in c urves.
Automatic post -collision braking system
The "Automatic post-collision braking system"
can he lp to reduce the risk of sliding and of
other coll is ions after an acc ident. If the airbag
control mod ule detects a collision above acer­
tain vehicle speed, the vehicle is braked by the
ESC.
The vehicle does not brake automatically if:
- the driver presses the accelerator pedal , or
- the braking fo rce genera ted by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle
electrical system are not functioning .
A WARNING ,.
- The ESC and its integrated systems can­
not overcome the lim its posed by natural
physical laws. This is especia lly impor­
tant on s lippery or wet roads. If the sys-
Switching on /off
terns begin acting to stabilize your vehi­
cle, you should immediately a lter your
speed to match the road and traffic con­
ditions . Do not let the increased safety
provided tempt you into taking r isks .
This could increase your risk of a co lli­
sion .
- Please note the r isk of a coll is ion increas­
es when driving fast, especially through
curves and o n slippe ry or wet roads, and
when dr iv ing too close to objects ahead.
The ESC and i ts integrated systems can­
not a lways p revent collisions -there is
still a risk of accidents!
- Press the acce lerator pedal caref ully
when acce lerating on even, slippery sur­
faces such as ice and snow. The drive wheels can spin even when these control
systems are installed and this can affect
driving stability and increase the risk of a
coll is io n.
(D Tips
- ABS and ASR only function correctly
when all four wheels are equ ipped w ith
identical t ires . Different t ire sizes can
lead to a reduction in engine power.
- You may hear noises when the systems
descr ibed are working .
- If the
DJ or [IJ indicator light appears,
there may be a malfunction¢

Fig. 1 50 Upper c ente r conso le : ESC but to n
The ESC is designed to funct ion in levels . De­
pending on the level that is selected, the sta­
bilization funct io n of the ESC is lim ited or
swit ched off . The amoun t of stabilization con ­
tro l will differ depending on t he level.
In the follow ing unusual situations it may
make sense to switch the ESC sport mode on
to allow the wheels to sp in:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground

192 Smart T echnol ogy
Corro sion
Leaving the vehicle parked for long periods o f
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake ro­
tors and di rty brake pads.
I f you usually avoid heavy brak ing or if there is
corrosion present, occasiona l heavy braking at
high speeds is recommended to clean the
brake rotors and pads¢,& .
Brake system malfunction
if you notice that the brake pedal t ravel has
suddenly gotten larger, then a brake circuit
may have failed. Drive to your authorized Audi
dealer or qualified repair facility immediately
to hav e the problem corrected . On the way
there, drive with reduced speed and keep in
mind that a long braking distance and in­
creased pressure on the brake pedal will be
necessary .
Lo w brake fluid level
When the brake fluid level is low, ma lfunc ­
tions in the brake system may occur. The
brake fluid level is electronically mon itored.
B rake bo ost er
The brake booster amplifies the pressure you
apply to the brake pedal. It only works when
the engine is running.
A WARNING ,~ ·
- You should only perform braking maneu­
vers to clean the brakes when the road
condit ions perm it. Never put others on
the road at risk -never forget the risk of
acc idents!
- On steep slopes, reduce the speed and
select a lower gea r or lowe r selector lev­
er position. Drive as litt le as poss ible
w hil e pressing the bra ke peda l and avoid
putt ing you r left foot on the brake pedal
whi le driving . This could cause the brakes
to overheat and impair the efficiency of
the brakes .
- Do not let the brakes "grind" by always
keeping yo ur foot on the brake peda l. This can cause the brakes to overheat
in-
,
crease wear and increase braking dis­
tance unnecessarily.
- Certain weather and operating condi­
tions such as driving through water, driv­
ing in heavy rain or driving after washing
your veh icle can impa ir the effectiveness
of the brakes . In the winter, ice may
bu ild up on the bra ke pads, rotors and
d rums. Che ck these components by b rak­
ing caref ully. App lyi ng the br akes care­
fu lly several times dries the brakes and
removes ice bui ld-up .
- The eff ic iency of the brakes can also be
impaired by driving for long stretches on roads covered with salt without using the
brakes. Yo u can remove salt deposits
from the brake rotors and pads by care­
fully applying the brakes several times.
- If the front spoiler is damaged or you in­
stall another spoiler, make sure the front
wheel brakes are ventilated properly.
Otherwise , the brake system could over ­
heat, wh ic h red uces their effectiveness .
- Failure of a brake circuit impa irs braking
performance, wh ic h increases bra king
d istance . Avoid driving the vehicle and
have it towed it to the nearest author­
i z ed A udi dealer or au thorized Aud i Serv­
ice Facility .
- Do not let your ve hicle roll w it h the en­
g ine switched off unde r any circumstan­
ces .
- If the b rake booste r is no t working, you
will have to press much harder on the b rake peda l to compensate for the lack
of the booster.
(D Note
- N ever le t the bra kes "rub" by pressing
t he pedal ligh tly when braking is not
really necessary . This causes the brakes
to overheat and increases braking dis ­
tance and causes wear .
- Before dr iv ing on a long stretch with
steep s lopes, reduce your speed and shift
to the next lower gear This makes use of
the engine brak ing effect and relieves .,.

194 Smart Technology
Winter tires By using all wheel drive, your vehicle has good
forward motion with standard tires in winter
cond itions. However, in winter we recommend
using winter or all season tires on
all four
wheels, because this will improve the braking
effect .
Snow chains
If there are snow chain laws, snow chains
must also be used on vehicles with all whee l
drive ¢
page 262, Snow chains .
Replacing tires
Fo r vehicles w ith all whee l dr ive , only wheels
with the same rolling circumference should be
used . Avoid whee ls with different tread
depths ¢
page 254.
Offroad vehicle?
Your Aud i is not an offroad vehicle -there is
not enough ground clearance. For this reason,
avoid difficult terrain. Refer to¢
page 287.
&_ WARNING
- Also, in vehicles with all whee l dr ive,
adapt yo ur driving style to the current
road and traffic conditions. Do not let
the increased safety provided tempt you
into taking risks.
- The braking ability of your vehicle is lim­
ited to the traction of the wheels . In this
way, it is not different from a two wheel
dr ive vehicle. Do not be tempted to ac­
celerate to a high speed when the road is
slippery this increases the risk of an acci­
dent .
- Note that on wet streets, the front
wheels can "hydroplane" if driving at
speeds that are too high. Unlike front
wheel drive vehicles, the engine does not
rev higher suddenly when the vehicle be­
gins hydroplan ing. For this reason, pay
attention to the road conditions regard­
less of your speed.
Energy management
The starting ability is optimized
The energy management system manages
the electrical energy distribution and optimiz ­
es the availability of electrical energy for
starting the engine.
When a vehicle with a conventional energy
system is not driven for a long time , the bat­
tery is drained by equ ipment (for example the
immobilizer). In certain circumstances, there
could may not be enough energy to start the
engine .
Your vehicle is equipped with an intel ligent
energy management system for d istr ibut ing
electricity. This s ignificantly improves the
sta rting ability and increases the battery life.
The energy management sy stem Is made up
of
battery diagnosis , idling current manage·
ment
and dynamic energy management .
Battery diagnosis
The battery d iagnosis determ ines the battery
charge leve l. The sensors determine the bat­
tery voltage, the battery current, and the bat­
tery temperature. The curren t cha rge leve l
and the performance of the battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used wh ile parked. With the engine
switched off, it manages the energy distribu­
tion to the different elect rical componen ts.
Date from battery diagnosis is taken into ac­
count for this.
Depending on the battery charge level, elec­
trical equip ment is switched off one item after
the o ther, to prevent the battery from drain­
ing and to retain the starting ability.
Dynamic energy management
While driving, dynamic energy management
distributes the appropriate amount of energy
to the e lectr ica l equipment.
It controls the
battery charge level so that more energy is ..,.

not used then is being generated in o rder to
maintain an optimal battery charge level.
@ Tips
- Energy management cannot overcome
the laws of physics. Note that the charge l evel and length of the battery life are
limited .
- When the start ing ability is endangered,
the (•) indicator light turns on
c!:>page20.
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is p laced on the battery when
driving short distances, in traffic , and at co ld
times of the year. A lot of energy is used but litt le is generated. It is also critical when the
engine is not running but electrical equip­ ment is switched on . In this case, energy is
used but none is generated .
In situations like this, energy management
will actively regulated the distribution of en­ ergy.
Long periods without use
I f you do not drive your vehicle for several
days or weeks, e lectrica l equipment is gradu­
ally sca led back or switched off . This reduces
energy use and ensures the vehicle will be
able to start after long periods of time. Some
conven ience functions such as opening with
the remote contro l key may not be ava ilab le.
These convenience functions will be available
again once you switch the ign ition on and
start the engine.
With the engine switched off For example, if you listen to the radio when
the engine is switched off, the batte ry w ill
drain .

~ tion could impair starting ab ility . co ,....,

Smart Technolog y 195
With the engine running
Although electrical energy is generated while driving, the battery can drain. This can happen
when litt le energy is generated, and much is
used and the charge leve l of the battery is not
optimal.
To restore the ba lance of energy, components
that require large amounts of energy are tem­
porari ly scaled back or switched off. Heating
systems in particular require a great deal of energy. If you notice, for example, that the
seat heating* or rear window defroster is not
working, then it has been temporar ily reduced
or switched off . These systems are availab le
again as soon as the energy balance has been
restored.
In add ition, you may notice that the idle
speed has slight ly increased . That is normal
and no cause for concern. Due to the in­
creased idling speed, the additional required
energy w ill be gene rated and the battery will
be charged.
Notice about data
recorded by the Event
Data Recorder and
vehicle control
modules
Event Data Recorder
This vehicle is equipped with an Event Data Recorder ( EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an airbag deployment or hitting a road obstacle, data that w ill assist in
understanding how a vehicle's systems per­
formed . Th e EDR is designed to record data
related to vehicle dynam ics and safety sys­
tems for a short pe riod of time, typically
30 seconds or less . The EDR in this vehicle is
designed to record such data as:
- How various systems in your veh icle were
operating;
- Whether or not the driver and passenger
safety belts were buckled/fastened;
