Stowing luggage
Loading the luggage compartment
All luggage and other objects must be prop­ erly stowed and secured in the luggage com ­
partment.
Fig . 184 Safe load pos ition ing: place heavy objects as
low and as far forward as possible.
Loose items in the luggage compartment can
shift suddenly, changing vehicle handling
characterist ics . Loose items can also increase
the r isk of serious personal injury in a sudden
vehicle maneuver or in a collision .
,. Distribute the load evenly in the luggage
compartment .
,. Always place and properly secure heavy
items in the luggage compartment as low
and as far forward as poss ible
¢fig. 184.
,. Secure luggage using the tie-downs provid­
ed
¢ page 80.
,. 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
personal inj ury in the event of hard brak­
ing or an acc ident. To help reduce the r isk
of serious persona l injury:
- Always put objects, for example, luggage
or other heavy items in the luggage com­
partment.
- Always secu re objects in the luggage
compartment us ing the tie-down eye lets
and suitable straps.
A WARNING
-Heavy loads wi ll influence the way your ve-
h icle ha ndles. To help reduce the risk of a
loss of control leading to serious personal
i njury:
-Always keep in mind when transporting
heavy objects, that a change in the cen­
ter of gravity can also cause changes in
veh icle handling:
- Always distribute the load as evenly as
poss ible.
- Place heavy objects as far forward in
the luggage compartment as possible.
- Never exceed the Gross Axle We ight Rat­
ing or the Gross Vehicle Weight Rating
specif ied on the safety compliance stick­
er on the left door jamb. Exceed ing per­
miss ible weight standards can cause the
veh icle to slide and handle differen tly.
- Please observe information on safe dr iv­
ing
¢page 160.
A WARNING
-
To help prevent poisonous exhaust gas
from being drawn into the vehicle, a lways
keep the rear lid closed while driving.
- Never transport objects larger than those fitting comp letely into the luggage
area because the rear lid cannot be ful ly
closed.
- If you absolutely m ust dr ive wi th the rear
lid open, observe the following notes to
red uce the risk of poisoning:
- Close all windows,
- Close the Panoramic sliding sunroof *,
- Open all air outlets in the instrument pane l,
- Switc h off the air recirculat ion,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win­
dows, the Panoramic sliding sunroof * and
the rear lid are securely closed and locked
-

,&_ WARNING
-Safety belts are the single most effective
means available to reduce the risk of se­
rious injury and death in automobile acci­
dents. For your protection and that of
your passengers, always correctly wear safety belts when the vehicle is moving .
- Failure to pay attention to the warning
light that come on, could lead to person­
al injury.
Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles.
Fig. 186 Unbelted occupants in a ve hicle heading for a
wall
Fig. 187 The vehicle cras 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.
Safety belts 1 71
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. 186, they will keep
moving at the same speed the vehicle was
moving just before the crash, until something
stops them -here, the wall¢
fig. 187.
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 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 col­
lisions.

172 Safety belts
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. 188 A driver not wearing a safety belt is violently
thrown forward
Fig. 189 A rear passenger not wearing a safety belt
will fly forward and strike the 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
wheel, instrument panel, windshield, or what­
ever else is in the way
q fig. 188. This impact
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. 189. 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. 190 Driver is correctly restra ined in a sudden brak­
ing maneuver
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 uncontrolled movement that can
cause 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
"absorbing" the kinetic energy over a longer
period of ti me, the safety belts make the
lilJJ,

prevent them from providing any
protection.
- An improperly insta lled child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child -even with an Advanced Airbag
System .
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sensing mat and can
cause i njury in a c rash .
Front airbags
Description of front airbags
The airbag sys tem can provide supplemental
protection to properly restrained front seat
occupants.

for the seats have "p retens ioners" that help
to take slack o ut of the be lt system. The pre­
tens ioners are also act ivated by the electronic
control unit for the airbag system.
T he front sa fety belts also have load limite rs
to help reduce the forces applied to the body
in a crash .
T he airbag for the drive r is in the stee ring
whee l hub
q fig. 196 and the airbag for the
front passenger is in the instrument panel
~ fig. 197 . The general locat ion of the a irbags
is marked "AIRBAG" .
There is a lot you need to know about the ai r­
bags in your vehicle . We urge you to read t he
detailed information about airbags, safety
belts and child safety i n this and the other
chapters that make up the owner's literature. Please be sure to heed the WARNINGS -they
a re extremely important for your safety and
the safety of yo ur passengers, especially in­
fants and small children.
_&. WARNING
N eve r rely on airbags alone for protec tion.
- Even w hen they deploy, airbags provide
only s uppleme ntal pro tect ion .
- Airbag work most effective ly when used
wit h prope rly wor n safety belts .
- Therefore , always wea r you r safety belts
and make sure that eve rybody i n your ve­
hicle is p rope rly res trained.
_&. WARNING
A pe rs o n on the fron t passe nger seat, es­
pe cial ly inf ants and sm all children, will re­
ceive serio us injuries and can even be kil­
l e d by being too close to the airbag when
it inflates .
- Altho ugh the Advanced Airbag System in
your veh icle is designed to tur n off the
front passenge r airbag if an infant or a
small child is on the front passenger
seat, nobody can absolutely guarantee
that deployment under these specia l
11>-

If the total weight on the front passenger
seat is more than that of a typical 1 year -old,
but less than the weight of a small adult, the
front airbag on the passenger side may deploy (the
P ASS ENGER AIR B AG OFF light does not
come on).
For example, th e airbag may depl oy if:
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld safety seats listed
<=) page 202),
-a chi ld who has outgrown child restraints is
on the front passenger seat.
I f the front passenger airbag is turned
off, the
PA SSENGER AIR B AG OFF light in the center
of the instrument panel wi ll come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PA SSENG ER AIR BAG O FF
light does not ill uminate and stay lit) if:
- a small adu lt or teenager is on the front pas­
senger seat
- a passenger who is not sitt ing upright w ith
their back against a non-reclined backrest
with their feet on the vehicle floo r in front
of the seat is on the front passenge r seat .
If the front passenger airbag deploys, the
Federal Standard requires the a irbag to meet
the " low risk" deployment cr iteria to help re ­
duce the risk of inju ry through interaction
with the airbag. "Low risk" deployment occurs in those crashes that take place at lower de­
celerations as defined in the electronic control
un it.
<=) page 190
Al ways rememb er: Even tho ugh your vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat. Please be sure to read the impor­
tant information in the sect ions that follow
and be sure to heed all of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag inflates, a lways wear safety belts prope rly.
A irbag system 185
-If you are unrestrained, leaning forward,
sitt ing s ideways or out of pos ition in any
way, your risk of injury is much higher.
- You will a lso receive serious injuries and
could even be killed if you are up aga inst
the airbag or too close to it when it in­
flates -even w ith an Advanced A irbag
<=)page 179.
A WARNING
-
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be ser ious ly injured and can be killed if
the front airbag inflates -even with an Ad­
vanced A irbag System.
- Al tho ugh the Advanced Airbag System in
your veh icle is designed to turn
off the
front airbag when a rearward -facing
child restraint has been insta lled on the
front passenger seat, nobody can abso­
lutely guarantee that dep loyment is im­
possible in all conceivable s ituations that
may happen dur ing the usefu l life of your
veh icle.
- The inflating airbag will h it the ch ild
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the bac krest, center
armrest, doo r, or roof.
- Always install rearward-facing chi ld re­
straints on the rear seat.
- If you must install a rearwa rd fac ing
child safety seat on the fro nt passenger
seat because of exceptiona l circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and s tay on, im ­
mediately insta ll the rear-facing ch ild
safety seat in a rear seating position and
have the airbag system inspected by your
author ized Audi dealer.
A WARNING
If, in except iona l circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem pe rforms in a crash. For example, using
tire-r im combinations not app roved by Aud i,
lowe ring the vehicle, ch anging the stiffness of
the suspension, incl uding the springs, s uspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the ai rbag
sensors and sent to the electronic control
un it. Some suspension changes can, for exam­
p le, increase the force levels measured by t he
sensors and make the airbag system deploy in
crashes in wh ich it would not dep loy if the
cha nges had not been made. Other k inds of
cha nges may reduce the force levels meas­
ure d by the sensors and preven t the a irbag
from deploying when it sho uld .
The senso rs in the safety belt buckle fo r th e
d river and front passe nger sea t tell the elec­
tronic control module if the safety belt is
l atched or not. I f the safety belt is being used,
the front airbag will deploy at a slightly high­ er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is poss ible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the position where t
he safety be lt is not being
used. It is important that nothing interfere
with the safety be lt b uckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control un it.
A WARNING
=
Changi ng the veh icle's suspension includ-
i ng use of unapp roved tire-rim combina­
tions can change Advanced Airbag per­
fo rma nce and increase the r is k of seri ous
personal injury in a cra sh.
- N ever install suspension components
that do no t have the same pe rformance
chara cter istics as the compone nts o rigi­
na lly ins talled on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
= -
It ems stored between the safety be lt
bu ckle and the cente r console can cause
the sensors in the b uckle to send the
wrong information to the e lectronic con­
trol module and prevent the Advanced Air­ bag System from working prope rly.
- Always make sure that nothing can inter­
fere with the safety belt buckles and that they are not obstructed .

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. EDRs are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDRs 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 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 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 Stability
Control (ESC)
General information
The ESC improves the vehicle stability.
. ..---------..
------- -
Fig. 218 Center console with ESC sw itch
ESC is designed to help you maintain vehicle
control in situations where the car approaches
the limits of "grip", especially when accelerat­
ing and cornering. ESC reduces the risk of
skidding and improves stability under all road
condit ions .
The system operates across the entire speed range in combination with the ABS system. If
the Anti-Lock Brake System (ABS) malfunc­
tions, the ESC will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Electronic
Differential Lock (EDL) and the Anti-Slip Regu­
lation System (ASR) are integrated in the Elec­
tronic Stability Control. In addition to the da­
ta provided by these functions, the ESC con­
trol unit requires additional measurement da­
ta provided by high performance sensors. The
rotational speed of the vehicle about its verti­
cal axis, vehicle acceleration in the fore-and­
aft and lateral directions, the brake pressure and the steering angle are all measured.
T he direction in wh ich the driver wishes to
travel is determined with the aid of the steer­
ing angle and vehicle speed and is continually
compared with the actua l behavior of the ve­
hicle. If the two do not match, for example,
when the vehicle starts hydroplaning on a wet
road, ESC will automatically brake the appro-
priate wheel to correct the problem. ..,_

220 Intellig ent technol ogy
The vehicle is then stabilized by the forces act­
ing on the whee l during braking. If the vehicle
is
oversteering (rear tends to sk id out of the
turn), the brakes are ma inly applied on the
wheel that is on the outside of the curve. In
the case of a vehicle that is
understeering
(tendency to slide out of the curve), the
brakes are applied as needed on the whee l
that is on the ins ide of the curve or addit ional­
l y on the o ther wheels. An acoustic s ignal indi­
cates when ESC b rake app lication cuts in
¢ A .
The system operates across the entire speed
range in combination with the ABS system
¢ page 223. If the Anti-Lock Brake System
(ABS) malfunctions, the ESC wi ll be out of ac­
tion as well .
Activating
When you turn on the engine, ESC w ill auto­
mat ica lly be act ivated and will perform a se lf­
test. As soon as the test is comp leted, the sys­
tem is in normal operating mode.
Offroad mod e
ESC should normally be ope rated in normal
mode because this ensures maximum vehicle
stability. If necessary, you can act ivate the
ESC offroad mode by pressing the but to n
¢ fig . 218 to obtain maximum traction and
braking ability when driving
off paved roads at
l ow speeds. In ESC offroad mode, the indica­
tor light
fi illuminates and the message Off ­
road control Warning! Red uced t ract ion
ap­
pears briefly in the display .
The ESC offroad mode can be usefu l in the fo l­
low ing except iona l situations when slip or a
h ighly effective differentia l locking function is
desirable . Examples:
- when driving with tire chains,
- when driving in deep snow or on loose
ground,
- when driving on uneven surfaces with the
wheels severe ly unloaded (articulation), and
- when rocking the vehicle loose after it has
become stuck.
When the unusua l situat ion is past, you
should shift back to the normal ESC operating mode by pushing the button again
. The mes­
sage
S tabilit y prog ram on then appears brief­
l y in the display.
H ill descent control
T he hill descent con trol is swi tched on in ESC
offroad mode . When slowly descending steep
gradients on loose gro und or when the axles
are articulated, hill descent control provides
ass istance by automatically applying the
brakes to keep vehicle speed constant. The ve­
hicle is also rendered easier to steer by selec­
t ive d istr ibut ion of braking force . H ill descent
control intervenes when:
- the acce lerator pedal is not pressed,
- the vehicle is travelling less than 12 mph
(20 km/h),
- a steep gradient is detected,
- wheel behavior indicates loose ground or
conditions with poor adhesion (e.g . a lso axle
articu lation).
Hill descent con tro l operates both d riving for­
ward and in reverse. Active hill descent con­
trol is deactivated by pressing the accelerator
pedal unti l the conditions for activation al­
ready listed are met again.
A WARNING
- The Electronic Stability Control is never­
theless subject to the laws of phys ics. It
is part icu larly important to pay attention
to this fact on wet and slippery roads. It is therefore impo rtant that you a lways
a dapt your d riving to the condit ion of the
road and traffic cond itions. Do not allow
the increased safety provided by the Electron ic Stability Control system to lull
you into accepting additional safety
risks.
- Please be aware that in ESC offroad
mode, particularly on a smooth and s lip­
pery road, the wheels may have an in­
creased tendency to spin and the vehicle
may break away - danger of skidding!
- Stability is limited in the ESC offroad
mode.
