Electronic stabilization
control (ESC)
Description
The Electronic Stabilization Control (ESC) rein for
ces driver safety . It reduces the risk of slipping
and improves driving stability. ESC detects crit i
cal s ituations such as the vehicle oversteering
and understeering or the wheels are spinning.
The vehicle is stabilized by applying the brakes or reducing eng ine torq ue. When the ESC engages,
the
D1 ind icator light blinks in the instrument
cluste r.
The fo llow ing systems are integrated in the ESC :
Ant i-loc k braking system (ABS)
ABS p revents the whee ls from locking whe n brak
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is acting to
s tabilize the vehicle .
Brake assist system
The brake assist system can decrease brak ing dis
tance . It increases braking power when the d river
presses the brake pedal quick ly in emergency sit
uations . You must press and hold t he b rake pedal
until the dangerous situat io n is over . In veh icles
with adapt ive c ruise control*, the bra ke as sist
sy stem is more sensitive if t he di sta nce detec ted
t o the vehicle ahea d is too sm all.
Anti-slip regulation (ASR)
ASR reduces eng ine power when the drive wheels
beg in sp inning a nd adapts the force to the road
conditions . This makes it easie r to start, acceler
a te and dr ive u p in clines.
Electronic differential lock (EDL )
The EDL brakes w heels that a re spinning and
transfers the drive power to the other drive
wheel or whee ls if t he ve hicle is equipped with a ll
wheel drive*) . T his funct ion is not av ailable at
h igher speeds.
116 I
n extreme cases, ED L automat ically swi tches off
to keep the brake on the braked whee l from over
heating. The veh icle is still working correct ly. ED L
will switc h on again automatically when condi
tions have returned to normal.
Steering recommendation
The ESC he lps to stabili ze the vehicle by cha nging
the steering torque.
Selective wheel torque control
Se lective w hee l to rque cont rol is used when d riv
i ng o n curves. The fron t whee l on the inside of
the curve or bo th whee ls on the inside 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 "A utomat ic pos t-coll is io n braking sy stem"
c a n hel p to reduce t he risk of sliding and o f othe r
collisions after an accident . If the a irbag cont rol
module detects a collision a bove a certain vehicle
speed, the vehicle is bra ked by the ESC.
The vehicle does not bra ke automatically if:
- the dr ive r presses the acce lerator pedal, or
- the braking force generated by the pressed
brake pedal is grea ter than the braking force
that wo uld be i nitiated by the system, or
- the ESC, the brake system o r the ve hicle elect ri
cal system are not func tioning .
A WARNING
- The ESC and its integ rated syste ms can not
o vercome the lim its posed by natural physi
c a l la ws. Thi s is espe cial ly import ant on sli p
pe ry o r we t roads. If the systems beg in act
ing to stabilize your ve hicle, yo u should im
mediately a lter your speed to matc h the
road and traffic condit ions. Do not let the
increased safety pr ovided tempt you into
taking risks . This cou ld increase your risk of
a co llision .
- Please note the r isk of a collis ion increases
when dr iv ing fast, especia lly t hrough c urves
and on slippery or wet roads, and when dr iv
ing too close to objects ahead. The ESC and
i t s in tegr ated systems cannot always .,..

prevent collisions -there is still a risk of ac
cidents!
- 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.

Driving safety
-Never place or install floor mats or other
floor coverings on top of already installed
floor mats. Additional floor mats and other
coverings will reduce the size of the pedal
area and interfere with the pedals .
- Always properly reinstall and secure floor
mats that have been taken out for cleaning.
- Always make sure that objects cannot fall
into the driver footwell while the vehicle is
moving . Objects can become trapped under
the brake pedal and accelerator pedal caus ing a loss of veh icle control.
Storing cargo correctly
Loading the luggage compartment
All luggage and other objects must be properly
stowed and secured in the luggage compart
ment.

Loose items in the luggage compartment can
shift suddenly, changing vehicle handling charac
teristics . Loose items can also increase the risk of
serious personal injury in a sudden vehicle ma
neuver or in a collision.
.,. Distribute the load evenly in the luggage com
partment .
.,. Always place and properly secure heavy items in
the luggage compartment as far forward as
possible .
.,. Secure luggage using the tie-downs provided
~ page 58.
.,. Make sure that the rear seatback is securely
latched in place .

A WARNING
Improperly stored luggage or other items can
fly through the vehicle caus ing serious per
sonal injury in the event of hard braking or an
accident. To help reduce the risk of serious
personal injury:
- Always put objects, for example, luggage or
other heavy items in the luggage compart
ment.
-Always secure objects in the luggage com
partment using the tie-down hooks and
suitable straps .
A WARNING
Heavy loads will influence the way your vehi
cle handles. To help reduce the risk of a loss
of control leading to serious personal injury:
- Always keep in m ind when transporting
heavy objects, that a change in the center of
gravity can also 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 Axle Weight Rating
or the Gross Veh icle 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 124.
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 fully 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 top,

Safety belts
Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo
ple riding in vehicles .
Fig. 128 Unbelted occupants in a veh icle headi ng fo r a wall
Fig. 129 The vehicle c rashes into the wall
The physical principles are simple. Both the vehi
cle and the passengers possess energy which var ies w ith vehicle speed and body weight . Engi
neers call this energy "k inetic energy."
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 us
ing safety belts~
fig. 128, they will keep moving
at the same speed the vehicle was moving just
before the crash, unti l something stops them -
here, the wall~
fig. 129.
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
136 (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 collision
they will also keep moving 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 in all kinds of accidents and collisions .
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. 130 A drive r not wea ring a safety belt is vio len tly
th row n forward
Fig. 131 A rea r passe nge r not wea ring a safety belt will fly
forward and st rike t he drive r
Unbelted occupants are not ab le 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 i n the way~
fig. 130 . This impact w ith the vehi
cle inter ior has all the energy they had just be-
fo re the crash .

Never rely on airbags alone for protection. Even
when they deploy, airbags provide on ly additional
protection. Airbags are not supposed to dep loy in
all kinds of accidents. A lthough your Audi is
equipped with airbags, all vehicle occupants, in
cluding the dr iver, 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 protect ion in those accidents in w hich
a ir bags are not supposed to deploy or when they
have already deployed. Unbelted occupants can
also be thrown o ut of the vehicle where even
more severe or fatal injur ies can occur.
It is also important for the rear passengers to
wear safety belts correctly . Unbelted passengers
in the rear seats endanger not only themse lves
but also the driver and other passengers
¢fig . 131. In a frontal collision they will be
thrown forward violently, where they can hit and
injure the driver and/or front seat passenger .
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. 132 Dr iver is correctly restra ined in a sudden b raking
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 se ri
ous injur ies. In addition, safety belts reduce the
danger of being thrown out of the vehicle .
Safety belts
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 ene rgy over a longer period of time, the
safety belts make the forces on the body more
"tolerab le" and less likely to ca use injury .
Although these examples are based on a frontal collision, safety be lts can also substantially re
duce the r isk of injury in other k inds 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. Acciden t statist ics 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 supp lemental airbags to do their job in a col
lision. For this reason, wearing a safety belt is le
gally required in most count ries including much
of the United States and Canada .
Although your Aud i is equipped with airbags, you
still have to wear the safety belts provided. Front
airbags, for example, are activated only in some
frontal collisions. The front airbags are not act i
vated in all frontal collisions, in side and rear col
lisions , 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 air bag
systems in your Audi . So, always wear your safety
belt and make sure everybody in your vehicle is
properly restrained!
Important safety instructions about safety
belts
Safety belts must always be correctly positioned
across the strongest bones of your body.
.,. Always wear safety belts as illustrated and de
scribed in this chapter.
.,. Make sure that your safety belts are always
ready for use and are not damaged.
137

Airbag system
-Therefore, always wear your safety belts and
make sure that everybody in your vehicle is
properly restrained.
- Always hold the steering wheel with both
hands on the outside of the steering wheel
rim at the 9:00 o 'clock and 3 :00 o'clock po
sitions to help reduce the risk of personal in
jury if the driver's airbag inflates .
- Never hold the steering wheel at the 12
o'clock position or with your hands any
where inside the steering wheel or on the steering wheel hub. Holding the steering
wheel the wrong way increases the risk of
severe injury to the arms, hands, and head if
the driver airbag deploys.
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 .
148
-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
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 for 3-
and 6-year-old children under the U.S . Fed
eral Standard if a child with electrical capac
itance greater than the combined capaci
tance of a typical one-year old infant re
strained in one of the forward facing or rear
ward-facing child seats with which your ve
hicle was certified is on the front passenger
seat and the other conditions for airbag de
ployment 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.

.&_ WARNING ,_
If, in exceptional circumstances, you must in
stall a forward-facing child restraint on the
front passenger's seat:
- Always make sure the forward-facing seat
has been des igned and certified by its man
ufacturer for use on a front seat with a pas
senger front and side airbag.
- Never put the forwa rd-facing child restraint
up against or very nea r the instrument pan
el.
- Always move the front passenge r seat to
the highest posit ion in the up and down ad
justmen t range and move it back to the
rearmost posit io n in the seat's fo re and aft
adjustment range, as far away from the a ir
bag as poss ible, before install ing the for
ward-facing chi ld restraint.
- Always make sure that the safety be lt upper
anchorage is behind the chi ld rest raint and
not next to o r in front of the c hild restraint
so that the safety be lt will be p roper ly posi
tioned.
- Always make sure that there is noth ing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occup ied by a person when it is
not , or to signal that it is occupied by some
one who is heavier than the person ac tually
si tting o n the sea t. T he presence of addi
tional objects could cause the passenger
front airbag to be turne d on when it should
be
off, or could cause the airbag to work in a
way that is d ifferent from the way it wou ld
have worked without the object on the seat.
- Make sure that the

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that t he Advanced Airbag System
pe rforms in a crash. For examp le, using tire-r im
comb inat ions no t approved by Audi, lowering the
ve hicle, changing the s tiffness of the suspens ion,
includ ing the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l unit . Some suspens ion 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 dep loy if
the changes had no t been made. Other kinds of
Airb ag sys tem
changes may red uce the force levels measured by
the sensors and prevent the airbag from deploy
i ng when it sho uld.
A WARNING
=
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance a nd in
crease the risk of serious personal injury in a
crash.
- Never install suspension components that do not have the same performance charac
ter istics as the components origina lly instal
led on you r vehi cle.
- Never use tire-rim combinations that have
not been approved by Audi.
