130 Safety belts
Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 123 Unbelted occupants in a ve hicle heading for a
wall
Fig. 124 The vehicle c ras hes into the wall
The physical principles are simple. Both the
vehicle and the passengers possess energy
which varies with vehicle speed and body
weight . Engineers call this energy ''kinetic en­
ergy ."
The higher the speed of the vehicle and the
greater the vehicle's weight, the more energy
that has to be "absorbed" in the crash .
Vehicle speed is the most significant factor . If
the speed doubles from 15 to 30 mph (25 to
50 km/h), the energy increases 4 times!
Because the passengers of this vehicle are not
using safety belts¢
fig. 123, they will keep
moving at the same speed the vehicle was
moving just before the crash, until something
stops them -here, the wall¢
fig. 124 .
The same principles apply to people sitting in
a vehicle 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 can reach
one ton (2,000 lbs. or 1,000 kg) or
more. At greater speeds, these forces are
even
higher.
People who do not use safety belts are also
not attached to their vehicle. In a frontal colli­
sion they wi ll also keep moving forward at the
speed their vehicle was travell ing just before
the crash. Of course, the laws of physics don't
just apply to frontal collisions, they determine what happens in all kinds of accidents 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!
Fig. 12S A driver not wea ring a safety belt is vio len tly
t hrown forward
Fig. 126 A re ar passe nger not wearing a safety belt
w ill fl y forw ard and strike t he drive r
Unbelted occupants are not able to resist the
tremendous forces of impact by holding tight
or bracing themselves . Without the benefit of
safety restraint systems, the unrestrained oc­
cupant will slam violently into the steering
whee l, instr ument panel, windshield, or what­
ever else is in the way r:!>fig . 125 . This impact II>-

with the vehicle interior has all the energy
they had just before the crash.
Never rely on air bags a lone for protec tion.
E ven when they deploy, airbags provide only
additional protection . Ai rbags are not sup­
posed to deploy in all kinds of accidents. Al­
though your Audi is equipped with a irbags, all
veh icle occupants, including the driver , must
wear safety belts correctly in order to min i­
mize t he risk of severe injury or death in a
crash .
Remember too, that airbags wi ll deploy on ly
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 a lready deployed . U nbelted
occupants ca n also be thrown out of the vehi ­
cle whe re even mo re severe o r fa tal in ju ries
can occur .
It is also impo rtant fo r the rear passenge rs to
wear safety belts co rrec tly. Unbe lted passen­
ge rs i n the rea r seats endanger no t on ly them­
se lves bu t also the driver a nd o ther passen­
gers
¢ fig. 126 . In a frontal collision they will
be thrown forward vio lent ly, where they can
h it and injure the dr iver 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!
F ig . 127 D river is correctly restra ined in a sud den bral<·
ing maneuve r
Safety belts used properly can make a big dif­
ference . Safety be lts he lp to keep passengers
in their seats, gradually reduce energy levels
Safety belts 131
applied to the body in an accident, and he lp
prevent the uncontrolled movement that can
ca use serio us injuries . In addition, safety be lts
reduce the danger of being thrown out of the
vehicle.
Safety be lts attach passengers to the car and
give t hem the benefit of being s lowed down
more gently or "softly" through the "give" in
the safety belts, crush zones and other safety
features enginee red into today's vehicles. By
"absorbing" t he kinetic energy over a longer
per iod of t ime, the safety be lts make the
fo rces on the body more "tolerable" and less
li kely to ca use inju ry.
Althoug h these examples a re based o n a fron­
ta l co llision, safety belts can a lso substantia l­
l y red uce the risk of in jur y in other kinds of
cr ashes. So, whethe r you're on a long trip o r
just going to the co rner store, a lways buckle
u p and make sure others do, too . Accident sta ­
tistics show that vehicle occupants properly
wearing safety belts have a lower risk of be ing
i njured and a much better chance of surviving
an accident. Properly using safety belts also
greatly increases the ability of the supplemen ­
ta l airbags to do the ir job in a collision . Fo r
th is reason, wearing a safety belt is legally re­
quired in mos t coun tries including much of
t he United States and Canada.
Althoug h your Aud i is equipped wi th a irbags,
you st ill have to wear the safety be lts p rov id­
ed . Front airbags, fo r example, a re activa ted
o nly in some frontal collisions. The fron t air­
bags are not act ivated in a ll fron tal coll isions,
in s ide and rear co llisions, in roll ove rs or in
cases where t here is not eno ugh deceleration
through impact to the front of the veh icle.
The same goes for the other a irbag systems in
your Audi . So, always wear your safety belt
and make su re everybody in your veh icle is
properly restrai ned!

Notice about data
recorded by veh ic le
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retrieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for example, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as well as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stab ilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the vehicle back under control by selectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
J.i) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It will not always be able to help out
under a ll cond itions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it would on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not towing a trailer.
Always adjust your speed and driving style to road, traffic and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
driver inattent ion. Instead, ESC improves the
possibility of keeping the vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti -slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering* and electronic i nteraxle differential lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certain s ituations when you need
less traction, you can switch
off ASR by press­
i ng the button~~
page 182, fig. 153 or
~ page 182, fig. 154. Be sure to sw itch ASR
on again when you no longer need less trac­
tion.
Anti-lock b ra king s ystem (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even d uring hard brak ing . Apply ste ady p res­
sure to the brake pedal. Do not pump the ped­
a l. A pulsing in the brake peda l indicates t hat
the system is he lping you to brake the vehicle.
Brake assist system
The brake assist system can decrease bra king
d istance. It increases braking power when the
d river presses the brake pedal quick ly in emer­
gency situations . You must press and hold the
brake peda l until the situation is over. In
veh icles w ith adaptive cru ise contro l*, the
brake assist system is more sensit ive if the
d istance detected to the veh icle ahead is too
small.
Anti- slip regulati on (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Elect ronic diffe renti al lo ck (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on again au-
Intellig ent technolog y 181
tomat ica lly when conditions have returned to
norma l.
Dynamic steering*
On vehicles with dynam ic steering*, ESC helps
stab il ize the s teer ing in crit ica l sit uat io ns.
Electronic interaxle differential lock* /
selective wheel torque control*
T he electronic i nteraxle differential lock (front
whee l dr ive) or the se lective whee l to rque
control (all-wheel dr ive) opera tes when dr iv­
ing thro ugh curves. The front wheel on the in­
side of the c urve or both whee ls on the inside
of the curve are braked selectively as needed .
This min imizes sliding in the front wheels and
allows for more precise driving through
cu rves . The applicable system may not acti­
vate when dr iv ing in wet or snowy conditions.
A WARNING
- ESC, ABS , ASR, EDL dynam ic steering*
a nd the elect ronic interaxle differential
loc k* /se lective wheel torque control*
cannot overcome the laws of physics .
This is especially important on slippery
or wet roads. If the systems begin acting
to stabilize your veh icle, yo u should im­
mediately change your speed to match
the road and traff ic conditions. Do not
let the increased safety provided by
these systems tempt you to take r isks.
Doing so will increase the risk of a loss of
veh icle contro l, col lision and ser ious per­
sonal injuries.
- Always adapt your speed to road, traffi c
and wea ther conditions. The risk of los­
ing contro l of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, ASR, EDL dynam ic steering* and the
electronic interaxle differentia l lock*/se­
lective whee l torque control* cannot p re-
vent co llisions . ..,.

Winter t ires
When driving in the winte r, your ve hic le with
a ll-whee l drive has an advantage, even with
regular t ires. In winter road conditions it may
be adv isable to mount winter tires (or all-sea­
son t ires) for improved dr iveability a nd brak­
ing: these t ires must be mounted on
all four
wheels . See also i=>page 237, Winter tires.

Where tire cha ins are mandatory on certain
roads, th is normally a lso applies to vehicles
with a ll-wheel drive

chains.
Replacing wheels /ti res
Vehicles w ith all -wheel drive must a lways
have tires o f the same size. Also avoid t ires
with d iffe rent tread depths . For details see
page
c:;> page 2 33, New tires and replacing
tires and wheels .
Off-Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road veh icle.
It is
therefore best to avoid rough t racks and un­
even terrain as much as possible . Also refe r to
<=;> page 188.
A WARNING
Always adjus t you r d rivi ng to roa d and tr af­
fic co ndition s. Do no t let the e xt ra s afety
a ff orde d by all -whee l dr ive tem pt you in to
taking extra risks .
- Alt hough the all-whee l dr ive is very e f­
f ec tive, a lways remember tha t br aking
ca pacity is limited by t ire traction . Yo u
sho uld the refore not dr ive at excessive
speeds on icy or s lippery road surfaces.
- On wet road s urfaces, be careful not to
dr ive too fast because the front wheels co
uld begin to slide o n top of the water
(aquaplaning). If t his should occur, you
will have no warn ing fr om a s udden in­
crease in eng ine speed as w ith a front­
wh eel drive veh icle . Always dr ive at
speeds wh ich are su ited to the road co n­
di tions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle wi th a conventiona l ener gy sys tem
is not driven for a long per io d of time, the bat­
te ry is discharged by idling current consumers
(e .g. immobilize r). In certain circumstances it
can res ult in there being insufficient energy
available to start the eng ine .
Intelligent energy management in your vehi­
cle hand les the dist ribution o f electr ica l ener­
gy. Start ing ability is markedly improved and
t h e life of the battery is extended .
Bas ica lly, energy management consists of
battery diagnosis , idling current manage­
ment
and dynamic energy management .
Battery diagnosis
Battery diagnosis contin uously de termines
t h e state of the battery . Sensors determine
batte ry voltage, battery current and battery
temperature. This determines the current
state of charge and t he power of t he battery .
Idling current management
Idling current management reduces energy
consumption while t he vehi cle is standing.
With the ign ition sw itched off, it controls the
energy supply to the various electrica l compo­
nen ts. Data from battery diagnos is is cons id­
ered .
Depend ing on the battery's state of charge,
individ ual consumers are gradually turned off ..,.
