Electronic stabilization
control (ESC)
Description
Electronic Stabilization Control (ESC) supports
driver safety.
It reduces the risk of slipping and
improves driving stability. ESC detects critical sit­
uations such as the vehicle oversteering and un­
dersteering or the wheels are spinning. The vehi­
cle is stabilized by applying the brakes or reduc ­
ing engine torque. When ESC engages, the
G1 in­
dicator light blinks in the instrument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
ing. 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 pedal indicates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
until the dangerous situation is over .
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, acceler­
ate and drive up hills .
Electronic differential lock (EDL)
EDL applies the brakes to a wheel that starts
spinning and transfers the drive power to the
other driving wheels. This function is not availa­
ble at higher speeds.
In extreme cases, EDL automatically switches
off
to keep the brake on the braked wheel from over­ heating. The vehicle is still working correctly. EDL
will switch on again automatically when condi­
tions have returned to normal.
88 Steering
recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
Selective wheel torque control
Selective wheel torque control is used when driv­
ing on curves. The front whee l on the inside of
the curve or both wheels on the inside of the
cu rve are braked selectively as needed. This al­
lows more precise driving in curves. The applica ­
ble system may not activate when driving in wet
or snowy conditions.
A WARNING
- The ESC and its integrated systems cannot
overcome the limits imposed by natural physical laws. This is especially important
on slippery or wet roads. If the systems be­
gin acting to stabilize your vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the increased safety provided tempt
you into taking risks. This could increase
your risk of a collision .
- Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv­ ing too close to objects ahead. The ESC and
its integrated systems cannot always pre­
vent collisions -there is still a risk of acci­
dents!
- Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal­
led and this can affect driving stability and
increase the risk of a collision.
(j) Tips
-The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems de­
scribed are working.

Safe dri ving
- Please observe information on safe driving
c>page 180.
A WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed whi le driving.
- Never transport objects larger than those
fitting completely into the luggage area be­ cause the rear lid cannot be fully closed .
- If you absolutely must drive with the rear lid
open, observe the following notes to reduce
the risk of poisoning:
- Close al l w indows,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed.
A WARNING
Always make sure that the doors, all windows
and the rear lid are securely closed and locked
t o reduce the ris k of injury when the vehicle is
not be ing used.
- After closing the rear lid, always make su re
that it is properly closed and locked.
- Never leave yo ur vehicle unattended espe­
cially with the rear lid left open. A chi ld
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out. Be­
ing trapped in a vehicle can lead to serious
persona l injury.
- Never let children play in or around the ve hi­
cle .
- Never let passengers ride in the luggage
compartment. Veh icle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.
@ Tips
- Air circulation helps to reduce window fog­
ging. Stale air escapes to the outside
through vents in the trim panel, on the left
side of the luggage compartment. Be sure
to keep these slots free and open.
186
- Th e tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B-pillar. The tire
pressure label lists the recommended cold
tire inf lation pressures for the vehicle at its
maximum capac ity we ight and the tires that
were on your vehicle at the time it was man­
ufactured. For recomme nded t ire pressures
for normal load condi tions, please see chap­
ter

Tie-downs
The luggage compartment is equipped with four
tie -downs to secure luggage and other items.

In a co llision , the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury . Items in the vehicle possess energy which
vary with vehicle speed and the weight of the i tem . Vehicle speed is the most significant factor.
For example, in a frontal collision at a speed of
30 mph (48 km/h), the forces acting on a 10 lbs
(4 .5 kg) object are about
20 times the normal
weight of the item. This means that the weight
of the item would sudden ly be about
200 lbs (90 kg) . You can imag ine the injuries that
a
200 lbs (90 kg) item flying freely through the
passenger compartment could cause in a colli­
sion like th is .

Safe ty belts
The warning light . in the instrument cluster
lights up when the ignit ion is switched on as a re­
minder to fasten the safety belts. In addition, a
warning tone w ill sound for a certain period of
time.
F a sten you r safet y be lt and make sure that your
pa sse nge rs also prope rly put on thei r safet y
belt s.
_&. WARNING
- Safety belts are the s ingle most effective
means ava ilable to reduce the risk of ser ious
i njury and death in automobile acc idents .
For yo ur protect ion and that of your passen­
gers, always co rrectly wea r safety be lts
when the vehicle is moving .
- Failure to pay attention to t he war ning light
that comes on could lead to persona l injury.
Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo ­
ple riding in vehicles.

F ig . 1 52 The veh icle c rashes into the w all

The physical princ iples are simple . Both the vehi ­
cle and the passengers possess energy which var­
i es with vehicle speed and body weight. Engi­
neers call this energy "kinetic energy."
The higher the speed of the vehicle and the greater the vehicle 's we ight, the more energy
that has to be "absorbed" in the crash .
Vehicle speed is the most sign ifican t factor. If
the speed doub les from 15 to 30 mph (25 to 50
km/h), the energy increases 4 times!
Beca use the passenge rs of this vehicle a re not us­
i ng safety belts ¢
fig. 151, they w ill keep moving
at the same speed the vehicle was moving just before the crash, until something stops them -
here, the wall
¢ fig . 152 .
The same principles apply to people s itting in a
vehicle that is invo lved 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 h igher
speeds, these forces are even greater.
People who do not use safety belts are a lso not
attached to their vehicle. In a frontal coll is ion
they will also keep mov ing forward at the speed
their vehicle was travelling just before the crash .
Of course, the laws of physics don 't just apply to
frontal collisions, they determine what happens i n a ll kinds of accide nts and co llisions .

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!
Fi g. 153 A dr iver not wear ing a safety belt is violently
thrown forward
F ig . 154 A rear passenger not wear ing a safety belt will fly
forward and strik e the driver
Unbelted occupants are not able to resist the tre­
mendous fo rces of impact by holding t igh t or
b racing themse lves. Wi thout the benefit of safe­
ty restraint systems, the unrestrained occupant
will slam violently into the steering whee l, in ­
strument panel, windsh ield, or whatever else is
in the way¢
fig. 153. This impact with the vehi­
cle interior has all the energy they had just be­
fore the crash .
Never rely on airbags alone for protection. Even
when they deploy, airbags prov ide on ly additional
protection . Airbags are not supposed to deploy in
all k inds of accidents. Although your Audi is
eq uipped w ith airbags, all vehicle occupants, in­
cluding the dr iver, must wear safety belts cor­
rect ly in o rder to minimize the risk of severe in­
jury or death in a crash.
Safet y bel ts
Remember too, that airbags will dep loy only
once and that your safety belts are always there
to offer protection in those accidents in which
airbags are not supposed to dep loy or when they
have already deployed. Unbelted occupants can
also be throw n out of the vehicle where even
more severe o r fatal injuries can occ ur.
It is also important for the rear passengers to
wear safety be lts correctly. Unbe lted passengers
in the rear seats endanger not only themselves
but also the driver and other passengers
¢
fig . 154 . In a frontal collision they will be
th rown forward v io le ntly, whe re they can hit and
injure the dr iver and/or fro nt sea t pa ssenger.
Safety belts protect
People think it's possible to us e the hands to
brace the body in a minor collision. It 's simply
not true!
Fi g. 1 55 Driver is correctly restrai ned in a su dde n brak ing
m aneuver.
Safe ty belts used p roperly can ma ke a big diffe r­
ence. Safety be lts help to keep passengers in
t h eir seats, gradually reduce energy levels ap­
plied to the body in an accident, and help prevent
the u ncontrolled movement that can cause ser i­
ous injuries. In addition, safety belts reduce the
danger of be ing thrown out of the ve hicle.
Safety be lts attach passengers to the car and g ive
them the benefit of be ing s lowed down more
gently or "softly" through the "give" in the safety
belts, crush zones and other safety features engi­
neered into today's vehicles . By "absorbing" the
kinetic energy over a longer period of time, the
safety belts make the fo rces on the body more
"tolerab le" and less likely to ca use in jury.

Airbag system
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds and/or by
being pushed into you as the airbag inflates.
- Always make sure nothing is in the front air-
bag deployment zone that could be struck
by the airbag when it inflates.
- Objects in the zone of a deploying airbag
can become projectiles when the airbag de­
ploys and cause serious personal injury.
- Never hold things in your hands or on your
lap when the vehicle is in use .
-
-Never place accessories or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or bulky) on the doors;
never attach then to the doors or the wind­
shield; never place them over or near or at­
tach them to the area marked .,AIRBAG" on
the steering wheel, instrument panel or the
seat backrests; never place them between
these areas and you or any other person in
the vehicle.
- Never attach objects to the windshield
above the passenger front airbag, such as
accessory GPS navigation units or music players. Such objects could cause serious in­
jury in a collision, especially when the air­ bags inflate.
- Never recline the front passenger seat to transport objects. Items can also move into
the deployment area of the side airbags or
the front airbag during breaking or in a sud­
den maneuver. Objects near the airbags can
fly dangerously through the passenger com­
partment and cause injury, particularly
when the seat is reclined and the airbags in­
flate.
A WARNING
A person on the front passenger seat, espe­ cially infants and small children, will receive
serious injuries and can even be killed by be­
ing too close to the airbag when it inflates.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the front
202
passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un­
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle.
- The Advanced Airbag System can deploy in accordance with the "low risk" option under
the U.S. Federal Standard if a child that is
heavier than the typical one-year old child is
on the front passenger seat and the other
conditions for airbag deployment are met.
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating position.
- For their own safety, all children, especially
12 years and younger, should always ride in
the back properly restrained for their age
and size .
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United States
Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS)
208 as applicable at the time
your vehicle was manufactured .
The front Advanced Airbag System supplements
the safety belts to provide additional protection
for the driver's and front passenger's heads and upper bodies in frontal crashes . The airbags in­
flate only in frontal impacts when the vehicle de­
celeration is high enough.
The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety belts. Rather, it is part of the overall occupant re­
straint system in your vehicle. Always remember
that the airbag system can only help to protect
you, if you are sitting upright, wearing your safe­
ty belt and wearing it properly. This is why you
and your passengers must always be properly re­
strained, not just because the law requires you to be.
The Advanced Airbag System in your vehicle has
been certified to meet the "low risk" require-
ments for 3 and 6 year-old children on the ..,.

Airbag syste m
& WARNING
A child in a rearward-facing chi ld seat instal­
led on the front passenger seat will be ser i­
ously injured and can be k illed if the front air­
bag inflates -even with an Advanced Airbag
System.
- Although the Advanced A irbag System in
you r vehicle is designed to tu rn off the front
airbag when a rea rwa rd-facing child re­
straint has been insta lled on the fron t pas­
senger seat, nobody can absolutely g uaran ­
tee that deployment is impossible in a ll con ­
ceivable situations that may happen during
the useful life of your vehicle.
- The inflating airbag w ill hit the child seat or
infant carrier w ith great force and will
smash the ch ild seat and child against the
backrest, center armrest, door, or roof.
- Always install rearward-facing ch ild re­
straints on the rear seat.
- If you must install a rearward fac ing ch ild
seat on the front passenger seat because of
exceptional c ircumstances and the
PASSEN­
G ER A IR BAG OFF,;; light does not come
on and stay on, immediately install the rear­
facing child seat in a rea r seating pos ition
and have the a irbag system inspected by
yo ur Audi dealer.
& WARNING
If, i n ex cept ional circumstances, you must i n­
sta ll a forward-facing chi ld restraint on the
front passenger's seat:
- Always make sure the forward-facing se at
has been designed and ce rtified by its man ­
ufacturer for use on a f ront seat with a pas­
senger front and side a irbag .
- Never put the forward -facing child restraint
u p against or very near the instrument pan­
el.
- Always move the front passenger seat to
the highest position in the up and down ad­
justment range and move it back to the
rearmost position in the seat's fore and aft
adjustment range, as fa r away from the air­
bag as possib le, before insta lling the for­
ward-facing child restra int.
204
-
- lways make sure that t he safety belt upper
anchorage is behind the ch ild restraint and
not next to or in front of the child restraint
so that the safety be lt will be p roperly posi­
tioned.
- Always make sure that there is noth ing o n
the front passenge r seat that will cause the
capacitive passenge r detection system in
the seat to signal to the Airbag System tha t
the sea t is occup ied by a perso n when it is
not, or to s ignal th at it is occupie d by some­
one who is heavier than the person ac tually
sitting on the seat . The presence of addi­
tional objects cou ld cause the passenger
front airbag to be turned on when it should
be off, or could cause the airbag to work in a
way that is d if f erent from the way it wou ld
have worked without the object on the seat.
- Make sure that the

time wheneve r the ig nitio n is swi tched on.
Advanced Airbag System components
The fro nt passenge r seat in your veh icle has a lot
of ve ry important parts of the Advanced A irbag
Syste m in it. These parts incl ude the capacitive
passenger detection system, wir ing, b racke ts,
and more . The con trol uni t monitors the system
on the front passenger seat when the ignition is
switched on and turns the airbag indicator light
on when a malfunction in the one of the system
components is detected<=>
page 209. Because
the front passenger seat contains important
parts of the Adva nced A irbag System, you must
take care to p revent it from being damaged.
Damage to the seat may prevent the Advanced
A irbag Sys tem for the front passenge r seat from
do ing its job in a crash .
The front Advanced Airbag System consists
of the following:
-Crash sensors in the front of the veh icle tha t
meas ure vehicle acce le ra tion/dece le ra tion to
prov ide in formation to the Advanced A irbag
System about the sever ity of the crash .
- An elect ronic contro l unit, with integ rated

- Work on the pyrotechnic circ uit interrupt ­
er must only be performed by a qualified
technicians who have the experience, in ­
formation and special tools necessary to
perform the work safely.
- If the vehicle or the circuit interrupter is
scrapped, all app licab le safety precautions
must be followed .

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash . For example, using tire-r im
comb inat ions not approved by Audi, lowering the
ve hicl e, chang ing the stiffness of the suspens io n,
in clud ing the spr ings, suspens ion str uts, shock
absorbers et c. can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l unit. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not deploy if
the changes had not been made. Other ki nds of
changes may reduce the fo rce levels meas ured by
the sensors and prevent the airbag from deploy­
in g when i t should .

A WARNING
-Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious persona l injury in a
crash.
- Never install suspension components that
do not have the same pe rformance charac­
teristics as the components o rigina lly ins tal­
led on your vehicle.
- Never use tire-rim combinations t hat have
not been approved by Audi.
