Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 140 U nbe lted occupa nts in a ve hicle hea ding for a
wall
F ig. 141 T he ve hicle c ras hes into t he wall
The physical principles are simp le. Both the
ve hicle and the passengers possess energy
which varies w ith vehicle speed and body
weight . Enginee rs call this energy "kinetic en ­
e rgy ."
The higher the speed of the vehicle and the greater the vehicle 's weight, the more energy
that has to be "absorbed" i n 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 inc reases 4 t imes !
Because t he passengers of t his ve hicle are not
using safety belts
c:> fig . 140, they w ill keep
moving at the same speed the vehicle was
mov ing just before the crash, unt il something
stops them -here, the wall
c:> fig . 141 .
The same pr inc iples apply to peop le sitting in
a vehicle that is involved in a frontal co llision .
Even at city speeds of 20 to 30 mph (30 to
50 km/h) , the forces act ing on the body can
Safety belts 133
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 sa fe ty belts are also
not attached to their vehicle. In a frontal coll i­
sio n they wi ll 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 in all kinds of acc idents and col ­
lis ions .
What happens to occupants not wearing
safety belts?
In crashes unbelt ed o ccupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!

Unbelted occ upants a re not able to resist the

or bracing themselves . Without the benefit of

ever else is in the way c:> fig . 142. This impact IJll-

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 injuries
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~
fig. 143. 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!
Fig. 144 Driver is correctly restra ined in a sudden brak·
ing maneuve r
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 uncon trolled movement that can
ca use 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
"abso rbing" 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 substantial­ 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 eno ugh 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!

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for 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 retr ieval 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.
Although 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 examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l 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 we ll 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 Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESC detects
Intelligent technology 179
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
JjJ 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 all conditions 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 tow ing a trailer.
A lways 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 inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road dur ing 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.

Braking
What affects braking efficiency?
Ne w brake p ads
During the first 250 miles (400 km), new
-
brake pads do not possess the ir full brak ing
effect, they have to be "broken in" first
c:> .&.. .,.

182 Intelligent technology
You can compensate for this slightly reduced
braking power by pushing harder on the brake
pedal. Avoid heavy braking loads d uring the
break-in per iod.
Operating condition s and d riv ing hab it s
The brakes on today 's automob iles are st ill
subject to wear, depending largely on operat ­
ing 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 author­
ized Audi dealer more often than specified in
the
Warra nty & Maint enance booklet . Failure
to have your brake pads inspected can result in red uced b rake pe rformance.
On steep slopes, you should use the brak ing
effect of the engine . Th is way, you prevent un­
necessa ry wear on the brake system. If you
must use yo ur brakes, do not hold the brakes
down continuously . P u mp the brakes at inter ­
va ls.
Operating noise
Noises may occur when braking depending on
the speed, braking fo rce and outside condi­
tions s uch as temperature and humidity .
Effect of w ater and ro ad s alt
In certain situat ions, for example after driving
through water, in heavy ra in, after overn ight
condensat ion or after washing your car, the
b rak ing effect can be reduced by moistu re or
ice on the bra ke roto rs and b rake pads . The
b rakes must be dried fi rst with a few caref ul
b rake app lications .
At higher speeds and with the w indshield w ip­
e rs turned on, the brake pads press agains t
the brake rotors for a short amount of time.
This occurs at regular intervals without the
driver noticing and provides for better brake response time under wet condit ions.
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 sa lt coating from brake d
iscs and pads with a few cautio us ap­
plications of the brake
Q ,&. .
Corrosion
The re may be a tendency for dirt to bu ild up
o n the brake pads and corros io n to fo rm on
the d iscs if the car is not driven regu la rly or
only for short trips with litt le use of the
brakes.
If the brakes a re not used frequently, o r if cor­
rosion 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
c> &. .
Faults in the brak e syst em
If you shou ld no tice a sudden increase in
brake pedal trave l, then one of the two brake
ci rcuits may have fai led
c> &. .
Lo w brake fluid lev el
Malfunctions can occu r in the bra ke system if
the b rake fluid level is too low. The brake f lu id
level is monitored electronically.
Brake booster
The brake booster increases the pressure that
yo u generate with the brake peda l. It works
o n ly when the engine is running .¢
&
Brake lining we ar status
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
through the open ings in the wheel. If neces­
sary, the wheel may be removed for th is i n­
spect io n ¢
page 249, Changing a wheel.
_&. WARNING
- New brake pads don't have the bes t stop­
p ing power and m ust be "bro ken-in" dur­
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal city driving.
You can compensate for this by pressing
the brake pedal more firmly. Th is also
applies later when new pads are instal­ led.

-You should perform braking maneuvers
for the purpose of clean ing the brake
system only if road condit ions permit.
Other road users must not be put at r isk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower d riving range . Do not ride
the brakes or hold the pedal down too
long or too often. This cou ld cause the
brakes to get hot and dimin ish braking
effi ciency.
- Do not "r ide the b rakes" by resting your
foot on the pedal when yo u do not intend
to brake. This may cause the b rakes to
overheat, premat ure wear and increased
stopp ing distance .
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and d rums . Carefully apply brakes
for a test. Brakes will dry and ice coat­ ings will be cleaned off afte r a few ca re­
f ul brake appl ications.
- Driv ing fo r an ex tended pe riod of time on
salt-covered ro ads w ithout using yo ur
brakes can also affect braking efficiency.
Clean off accumu lated salt coating from
brake discs and pads with a few caref ul
brake applicat ions.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed. Otherwise the brake system co uld
overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake c ircuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­
est author ized Audi dealer or qualified
wor kshop.
- Never let the v ehicle roll to a stop w ith
t he engine shu t off.
Int ellig ent technolog y 183
-If the brake booster is not working, for
examp le when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed conside rably harder to make up
for the lack of booster assistance .

Driving with your
quattro®
App lies to vehicles: with all-wheel dr ive
-
With all-wheel drive, all four wheels are driv­
en.
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 179.
A center differential distributes the driving
power variably to the front and rear axle . It
works together with selective wheel torque control, which activates when driving through
curves
c> page 180. With the sport differen­
tial*, power distribution to the rear wheels is
variable and can be adjusted with drive select
c:>page 107.
The all-wheel drive concept is designed for
high engine power . Your vehicle is exception­
ally 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-sea­
son tires) for
improved driveability and brak­
ing: these tires must be mounted on all four
wheels. See also ¢ page 242, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also applies to vehicles
with all-wheel drive¢
page 243, Snow
chains .
Replacing wheels/tires
Vehicles with all-wheel drive must always
have tires of the same size. Also avoid tires
with different tread depths. For details see
page
c> page 238, 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 vehicle.
It is
therefore best to avoid rough tracks and un­
even terrain as much as possible. Also refer to
c:> page 187.
_& WARNING
-Always adjust your driving to road and traf-
fic 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 ef­
fective, always remember that braking
capacity is limited by tire traction. You
should therefore 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
(aquaplaning). If this should occur, you
will have no warning from a sudden in­
crease in engine speed as with a front­
wheel drive vehicle. Always drive at speeds which are suited to the road con­
ditions - 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 with a conventional energy system
is not driven for a long period of time , the bat­
tery is discharged by idling current consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insuff icient ene rgy
avai lab le to start the engine .
Intell igent energy management in your vehi­
cle hand les the d istribution of electrical ener­
gy. Starting ab il ity is markedly improved and
the life of the battery is extended.
Basically, energy management consists of
batt ery di agno sis, idlin g current man ag e­
m ent
and dyn ami c en ergy m anage ment .
Batter y diagnosis
Battery diagnosis continuously determines
the state of the battery . Sensors determ ine
battery vo ltage, battery current and battery
temperature. This dete rm ines the current
state of charge and the powe r of the battery.
Idling curr ent man agement
Idling current management reduces ene rgy
consumption while the vehicle is stand ing .
W ith the ignition switched off, it cont ro ls the
energy supply to the va rious electr ical compo ­
nents . Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
i nd ividua l consumers are gradual ly t urned off
to prevent excess ive d ischarge of the bat tery
and thus maintain starting capability .
Dynamic en ergy management
While the vehicle is being driven, dynamic en­
e rgy management dist ributes the energy gen­
e rated according to the needs of the individu­
a l components.
It reg ulates cons umption, so
that more electrical energy is not being used
Int ellig ent technolog y 185
than is being generated and ensures an opti ­
mal state of charge for the battery.
(0 Tips
- But even energy management canno t
negate the limits of physics . Consider
that the power and life of a battery are
limited .
- If starting ability is threatened, the indi­
cator light (•) appears~
page 17.
What you should know
The highest priority is given to maintaining
starting capability.
T he bat tery is severe ly taxed in short-distance
driving, in city traffic and during the cold time
of year. Ab undant electrical energy is re­
quired, but on ly a little is generated .
It is also
critica l if the engine is not running and electri­
ca l components are turned on . In this in­
stance energy is be ing consumed but none is
being generated .
It is in precisely these situations that you will
notice energy management active ly regulat­
ing the d istribution of energy.
V ehicle stand s for an ex tend ed peri od
If you do not drive your vehicle over a period
of severa l days or weeks, e lectrica l compo­
nents are gradually cut back or switched off.
This reduces energy consumption and ma in­
ta ins start ing capability over a longer period .
Some of the convenience functions may not
operate, such as the interior l ights or the
power seat adjustme nt. The convenience
funct ions w ill be available again when you
swi tch on the ignition and sta rt the eng ine .
With the eng in e turn ed off
If you listen to the radio, for example, w ith
the engine tu rned off or use other MMI func­
tions, the battery is be ing d ischarged.
If starting capability is jeopardized due to en ­
ergy consumption, the following warning ap- pears in the MM I display: ..,.
