Intelligent Technology Electronic Stabilization
Control (ESC)
Description
Elect ronic stabili zation control ( ESC) supports
driver safety. It red uces the risk of slipping and
improves dr iving stabi lity. ESC detects crit ica l sit­
uations such as the vehicle overstee ring and un­
dersteeri ng or the w heels are sp inning. The vehi­
cle is stabilized by app lying the brakes or reduc ­
i n g e ngine torque . When the ESC engages, the
G1 indicato r light bli nks in t he instr ument clus­
t er.
The fo llow ing systems are in tegrated in the ESC:
Anti-lock braking system (ABS)
ABS p reve nts the whee ls from lock ing whe n brak ­
ing. The vehicle can st ill be steered even d uring
hard brak ing. Apply steady press ure to the bra ke
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is act ing to
s tabili ze the vehicle .
Brake assist system
The brake assist system can decrease brak ing dis­
tance . It inc reases brak ing power when the d river
presses the brake pedal q uick ly in eme rgency sit­
uations . You must press and hold t he b rake pedal
until the dangerous si tuatio n is ove r. In veh icles
w ith adapt ive c ruise con trol*, the bra ke assist
sys te m is more sensitive if t he di stan ce detec ted
t o the veh icle dr iv ing ahead is too small.
Anti-Slip Regulation (ASR)
ASR reduces eng ine power when the drive wheels
beg in s pinning a nd adapts the force to the road
conditions . T his makes it easie r to sta rt, acceler­
a te and dr ive u p hill s.
Electronic differential lock (EDL)
The EDL applies the brakes to a whee l t h at starts
sp inning and transfe rs t he d rive power to t he
other d riving wheel or wh eels ( if the veh icle is
eq uipped w ith all whee l dr ive*) . T his func tion is
no t a vailable at hig her s pee ds .
148
In extreme cases, ED L automat ica lly swi tches off
to keep the b rake o n the bra ked whee l from over ­
h eating. The ve hicle is still wo rking co rrect ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Power steering
The ESC can also support veh icle sta bility
th ro ugh stee ring .
Selective wheel torque control
Selective w heel to rque cont rol is used when driv­
in g on curves. The fron t whee l on the in side of
t h e curve or both whee ls on t he i nsid e of the
cu rve are braked se lective ly as needed. This al ­
l ows mo re precise driving in cu rves .
Automatic post-collision braking system
The "automat ic pos t-coll is io n braking syste m"
c a n help t o reduce t he risk of sliding and of addi ­
tion al collisions a fter an acc iden t. If the a irbag
contro l modu le detects a collision above a certa in
vehicle speed, the ve hicle is braked by the ESC.
The
ve hicle does not br ak e automatically if;
- t he dr ive r presses the acce lerato r pedal, or
- the ESC, the b ra ke system or the ve hicle elect ri-
cal sys tem are not func tioning .

Loose items in the luggage compartment can
shift suddenly, chang ing vehicle handling charac­
ter istics . Loose items can also increase the risk of
serio us personal inj ury in a sudden vehicle ma­
ne uver or in a coll ision.
• Distribute the load evenly in the luggage com­
partment.
• Always place and properly secure heavy items in
the luggage compartment as far forward as
poss ible.
• Secure luggage using the tie-downs provided
¢ page 63.
• Make sure that the rear seatback is securely
latched in place .
A WARNING
Improperly stored luggage or other items can
fly through the vehicle causing serio us per­
sonal injury in the event of hard braking or an
accident . To help reduce the risk of serious
personal injury:
- Always put objects, fo r example, luggage o r
other heavy items in the luggage compart­ ment.
- Always sec ure objects in the luggage com­
partment using the tie-down hooks and
s u itable straps .
Driving safety
A WARNING
Heavy loads will influence the way your vehi­
cle handles. To help reduce the risk of a loss
of control lead ing to serious personal injury:
- Always keep in m ind when transport ing
heavy objects, that a change in the center of
gravity can a lso cause changes in vehicle
handling :
- Always distribute the load as evenly as
possible .
- Place heavy objects as far forward in the luggage compartment as possible.
- Never exceed the Gross Ax le Weight Rating
or the G ross Vehicle Weight Rating specified
on the safety compliance sticker on the left
door jamb. Exceeding permissible we ight
standards can cause the vehicle to slide and handle differently.
- Please observe information on safe driving
¢page 249 .
A WARNING
-
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving.
- Never transport objects larger than those
fitting completely into the luggage area be ­
cause the rear lid cannot be fu lly closed.
- If you absolutely must dr ive with the rear lid
open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the power roof*,
- Close the power top*,
- Open alt a ir outlets i n the instrument pan-
el,
- Switch off the air rec irculat ion ,
- Set the fresh air fan to the highest speed.
A WARNING
--
Always make sure that the doors , all win­
dows, the power roof*, the power top* and
the rear lid are securely closed and locked to
r educe the risk of injury when the vehicle is
n ot being used.

injury and death in automobile accidents.
For your protect ion and that of your passen­
gers, always correctly wear safety belts
when the vehicle is moving .
- Failure to pay attention to the warn ing light
that come on, could lead to personal injury.
Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo­
ple riding in vehicles .
Fig . 225 Unbe lted occupants in a veh icle head ing fo r a wall
Fig . 2 26 The ve hicle c rashes into the wall
The physical principles are simple . Both the vehi­
cle and the passengers possess energy which var­
ies w ith veh icle speed and body we ight. Engi­
neers call this energy "k inetic 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 signif icant facto r. If
the speed doubles from 15 to 30 mph (25 to
SO km/h), the energy increases 4 times!
Because the passengers of t his veh icle are not us­
ing safety
belts ~ fig. 225, they will keep mov ing
Safet y bel ts
at the same speed the vehicle was moving just
before the crash, until something stops them -
here, the
wall ~ fig. 226 .
The same p rinciples apply to people s itting in a
vehicle that is invo lved in a fronta l co llision. Even
at city speeds of 20 to 30 mph (30 to SO km/h),
the forces acting on the body can reach one ton (2,000 lbs, o r 1,000 kg) or more. At greater
speeds, these forces are even higher.
People who do not use safety belts are a lso not
attached to the ir vehicle . In a frontal col lis 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 wha t happens
in a ll kinds of accidents and co llisions .
What happens to occupants not wearing
safety belts?
In crashes unbelted oc cupants cannot stop
them selves from flying forward and being in­
jured or killed. Always wear your safety belts!

Safety belts
Unbelted occupants are not able to resist the tre­
mendous forces of impact by holding tight or
bracing themselves. Without the benefit of safe­
ty restraint systems, the unrestrained occupant
will slam violently into the steering wheel, in­
strument panel, windshield, or whatever else is
in the
way ¢ fig. 227. 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 provide only add itional
protection . Airbags are not supposed to deploy in
all kinds of accidents. Although your Audi is
equipped with airbags, all vehicle occupants, in­
cluding the driver, must wear safety belts cor­
rectly in order to minimize the risk of severe in­
jury 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 vehicle where even
more severe or fatal injuries can occur.
It is also important for the rear passengers to
wear safety belts correctly. Unbelted passengers
in the rear seats endanger not only themselves
but also the driver and other passengers
c> fig . 228 . In a frontal collision they will be
thrown forward violently, where they can hit a nd
injure the driver and/or front seat passenger.
262
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. 229 Driver is correctly res trained in a sudde n braking
maneuver
Safety belts used properly can make a big differ­
ence . Safety belts help to keep passengers in
their seats, gradually reduce energy levels ap­
plied to the body in an accident, and help prevent
the uncontrolled movement that can cause seri­
ous 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 engi­
neered 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 frontal
collision, safety belts can also substantially re­
duce 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 statistics show that vehi­
cle 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 supplemental airbags to do their job in a col­ lision. For this reason, wearing a safety belt is le­
gally required in most countries including much
of the United States and Canada.

Airbag syste m
-Never hold the steering whee l at the 12
o'clock pos it ion or w ith your han ds any­
where inside the steering wheel or on the steering wheel hub. Holding t he steering
wheel the wrong way increases the risk of severe injury to the arms, hands, and head if
the d river a irbag deploys.
A WARNING
Objects between you and the a irbag w il l in­
crease the risk of inj ury in a crash by interfer­
ing w ith the way the airbag unfo lds 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 str uck
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 persona l injury .
- Never hold th ings in your hands or on your
lap when the vehicle is in use.
- Never place accessor ies or other objec ts
(s uch as c up ho lders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, o r 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 p lace them between
these a reas and yo u or any other person in
the vehicle.
- Never attach objects to the w indshield
above the passenger front airbag, s uch as
accessory GPS navigation uni ts or mus ic
players . S uch objects could ca use serio us 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 a irbags or
the front a irbag during breaking o r in a sud­
den maneuver. Objects near the airbags can
fly dangerous ly through the passenger com­
partment and cause injury, particularly
when the seat is reclined and the airbags in­
flate.
274
A WARNING
A person on the front passenger seat, espe­
cially infants and small ch ildren, wi ll receive
serious in juries and can even be k illed by be­
ing too close to the airbag when it inflates .
- Although the Advanced Airbag System in your veh icle is designed to turn off the front
passenger airbag if an infant o r a small child
is on the fron t passenger sea t, nobody can
absolu tely guarantee tha t deployment un­
de r these specia l condi tions is impossible in
all conceivable situations that may happen
during the useful life of yo ur vehicle.
- The Advanced Airbag System can dep loy in
accordance with the
,. low risk" option for 3-
and 6-year-old children under the U.S. Fed­
eral Standard if a child w ith electrical capac­
itance greater than the combined capac i­
tance of a typical one-year o ld infant re­
strained in one of the forward facing or rea r­
ward-facing chi ld seats with which yo ur ve­
hicle was certified is on the front passenger
seat and the o ther conditions for airbag de-
ployment are me t.
- Accident s tatisti cs have shown th at children
are generally safer in the rear seat are a than
in the front seat ing pos ition.
- For their own s afety, all ch ildren, especi ally
12 years and younger, should alw ays ride in
the back proper ly 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 208, as
well as Canada Motor Veh icle Safety Standard
(CMVSS) 208 as applicable at the t ime your vehi­
cle was manufactu red .
The front Advanced A irbag System supplements
the safety belts to provide add itiona l protect ion
for the driver 's and front passenger's heads and
upper bod ies in fronta l crashes. The a irbags in­
flate only in frontal impacts when the vehicle de-
ce le ra tion is high e no ugh.
