prevent the vehicle from "creeping", you
must keep your foot on the b rake in all
selector lever positions except
P and N
when the eng ine is running. Do not inad­
vertent ly press the accelerator pedal
when the veh icle is stationary . Otherwise
the vehicle will start to move immediate­
ly . T his cou ld happen even if the parking
brake is activated.
- Before opening the hood, select the
P se­
lector lever position and set the parking
brake. Th is reduces the risk of a crash . Al­
ways read and follow the applicable
warnings¢
page 216, Engine compart­
ment .
-Never get out of the driver's seat when
the engine is runn ing . -
If you must get out of the vehicle, move
the selector lever secure ly into the P po­
sition and apply the parking brake firmly.
@ Tips
- If you unintentionally shift into the N se­
lector lever position whi le driving, take
your foot off the accelerator pedal and
wa it for the engine to slow down until it
is idling before you sh ift into Dor

General information
Applies to vehicles: with Home link® universal remote
control
The Homelink universal remote control can
be programmed with hand -held transmitters
from existing equipment.
Using the Homelink universal remote control,
you can operate equipment such as garage
doors, property gates and house lights from
ins ide your vehicle .
Using the Homelink universal remote control,
you can replace up to three separate hand­
held transmitters for equipment on your
property with just one universal remote con­
trol. Most of these transmitters are used to
ope rate ga rage doo rs and property gates. The
individual transmitters are programmed at
the front bumper. That is where the control
module is located.
The transmitters must be programmed first in
order to operate systems using the Homelink
universal remote control.
.&_ WARNING
-
-Never use the Homelink ® transmitter
with any garage door opener that does have not the safety stop and reverse fea­
ture as required by federal safety stand­
ards . This includes any garage door open­
er model manufactured before April 1, 1982.
- A garage door opener which cannot de­
tect an object, signa ling the door to stop
and reverse does not meet current feder­
al safety standards . Using a garage door
opener witho ut these features increases
risk of serious injury or death.
- For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may
sometimes be set in motion when the Homelink
® remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, this can overstrain motor and
damage its electrical components - an

138 Safet y belts
-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.
F ig. 1 39 Unbelt e d occ upants in a ve hicle h eading for a
wall
Fig. 1 40 The vehicle c rash es into t he wall
The physical principles are simp le. Both the
vehicle and the passengers possess energy
which varies w ith veh icle speed and body
weight . Engineers call this energy "kinetic en­
e rgy ."
The higher the speed of the vehicle and the
g reater the vehicle's we ight, the more energy
that has to be "absorbed" in 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 the passengers of this veh icle are not
using safety belts¢
fig. 139, they will keep
mov ing at the same speed the vehicle was
mov ing just before the c rash, unt il something
stops them - here, the wall ¢
fig. 140 .
The same principles apply to people s itting 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 (2,000 lbs , or 1,000 kg) or
more . At greater speeds, these forces are even
highe r.
Peop le who do not use safety belts are also
not at tached to their vehicle. In a frontal colli­
s io n they will 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 i n all kinds of a cciden ts and col­
li sions .
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!

thrown fo rwa rd
F ig . 14 2 A re ar passe nge r no t wea ring a sa fety be lt
w ill fl y forward a nd strike the dr iver
Un belted oc cupants a re not able to resist the
t remendous forces o f impac t by ho lding tight
o r bracing themse lves. Without the benefit of
safety restraint systems , the unrestrained
ll-

occupant will slam violently into the steering
wheel, instrument panel, windshield , or what­
ever else is in the way
c::> fig. 141. 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
c::> fig. 142. 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. 143 Driver is correct ly res trained in a sudden brak­
ing maneuve r
Safety belts 139
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 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 su bsta ntia l­
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 enough 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!

190 Intelligent technology
Intelligent technology Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facture rs for the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "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.
A lthough 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, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal 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 ve ry limited pe riod of
time and stored when a system fault or other
cond ition is sensed by a control unit. Some of
the data then stored may re late 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
program (ESP)
Description
ESP helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the engine is running. ESP detects certain difficult driving situat
ions, 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 steer ing assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
liJ in the instrument cluster
blinks when ESP is taking action to help you
control the vehicle.
ESP has limitations.
It is important to remem­
ber that ESP 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, ESP 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 w ith water,
slush or snow, ESP cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESP 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, ESP cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESP is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic; and weather condit ions. ESP can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a ve hicle
on the road if road departure is a result of
driver inattention. Instead, ESP improves the
poss ibility of keeping the vehicle unde r con­
trol and on the road during 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 ESP can
provide any assistance, you may not experi­
ence the benefits of ESP .
