8_ WARNING
-The vehicle can also roll when the engine
is stopped .
- Unintended vehicle movement can cause
serious injury.
- Never leave your vehicle with the engine running whi le in gear. If you must leave
your vehicle when the engine is running, act ivate the park ing brake and move the
selector lever to P.
- Power is st ill transmitted to the wheels
when the eng ine is running at idle . To
prevent the vehicle from "creeping", you
must keep your foot on the b rake when
the engine is runn ing and the se lector
lever is in D/S or R or "tiptronic" mode is
selected .
- Do no t press the accelera tor pedal when
changing the selector lever position
whi le the vehicle is stationary and the
engine is running.
- Never shift into
R or P whi le driving.
- Be fore driv ing down a steep slope, re -
duce you r speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
peda l too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substant ially re­
duces braking performance, increases
braking d istance or causes comp lete fail­
ure of the brake system.
- To prevent the veh icle from rolling back
when stopping on inclines, always hold it in place with the brake peda l or parking
brake.
- Never hold the veh icle on an incl ine with
a slipp ing clutch . The clutch opens auto­
matically when it becomes too hot from
the ove rload. An ind icator lamp
[O] illu­
minates and a dr iver message appears
¢ page 114 when the clutch is overload ­
ed.
- If the eng ine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and is locked in P w
it h the park ing brake set
¢ page 227. Otherw ise, any increase in
engine speed may set the vehicle in mo­
tion, even with the parking brake ap­ plied.
(D Note
- When stopping on an incl ine, do not try
to hold t he vehicle in place by pressing
the acce lerator pedal while a driving gear
is se lected. This ca n cause the transmis­
sion to ove rheat and can damage it . Acti­
vate the pa rking brake or press the bra ke
peda l to preven t the vehicle from roll ing.
- Allowing th e vehicle to ro ll when the en­
gine is stopped and the selecto r lever is
in N will d amage the tr ansmission be­
cause it is not l ubricated unde r those cir ­
cumstances .

Hill descent control
Appl ies to vehicles: wit h S t ronic/tiptro nic
The hill descent control system assis ts the
driver when driving down declines.
Hill des cent con trol is activated when these­
lector lever is in D/S and yo u press the brake
peda l. The transmission automatica lly selects
a gear that is suitable for the incline . Hi ll de ­
scent contro l tries to maintain the speed ach ­
ieved at the time of braking, within phys ica l
and technical lim itations. If may st ill be nec­
essary to adjust the speed with the brakes .
Hill descent cont ro l switches off once the de­
cline leve ls out or you press the acce lerator
pedal.
On vehicles with the cruise contro l system*
¢ page 84, hill descent control is also activat-
ed when the speed is set. .,..

A WARNING
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
conditions. Always be ready to apply the
brakes.

Universal remote
control
General information
Applies to vehicles: with Homelink u nive rsal remote con­
tro l
The HomeLink universal remote control can
be programmed with hand-held transmitters
from existing equipment.
With Homelink, you can control devices such
as the garage door, security systems, house
lights, etc. comfortably from the inside of you
vehicle.
Homelink makes it possible for you to replace
three different remote controls from devices in your home with one universal remote . Th is
feature works for most garage door and exte­
rior door motor signals. Programming the in­
d iv idual remo te control fo r your remote con ­
trol takes p lace near the center of the radiator
grille. There is a control module attached at
this location .
A one-t ime programm ing of the sensor mus t
be performed before you are able to use sys­
tems w ith Homelink.
A WARNING
- Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as requ ired by federal safety stand­
ards. Th is includes any garage door open­
er model manufactured before April 1, 1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards . Us ing a garage doo r
opener witho ut these fea tures 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
overheated motor is a fire hazard!
- To avo id possible injuries or property
damage, please always make absolutely
certa in that no persons or objects are lo­
cated in the range of motion of any
equ ipment being operated.

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 151 Unbelted occupants in a ve hicle heading for a
wall
Fig. 152 The vehicle cras hes into the wall
The physical principles are simple. Both the
vehicle and the passengers possess energy
which varies w ith veh icle 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.
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 t imes!
Because the passengers of this vehicle are not
using safety belts
c:::;, fig. 151, they will keep
moving at the same speed the vehicle was
mov ing just before the crash, until something
stops them - here, the wall ¢
fig. 152.
Safety belts 141
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 app ly to frontal collisions, they determine
what happens in all kinds of accidents and col­
lisions.
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. 153 A driver not wea ring a safety be lt is vio lently
th rown forward
Fig. 154 A rear passenger not wearing a safety belt

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 .,..

occupant will slam violently into the steering
wheel, instrument panel, windshield, or what­
ever else is in the way
c::> fig. 153. This imp act
with the vehicle interior has all the energy
t hey had just before the crash.
Never rely on a irbags 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 othe r passen­
gers ~
fig. 154. 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. 155 Driver is co rr ect ly re strain ed in a sudd en brak­
ing maneuve r
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 tha t 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
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 substantial­
ly reduce the r isk 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 no t enough decelera tion
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!

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 fo r 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 examp le, 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 very limited pe riod 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 Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the engine is running. ESC 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 steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under all conditions you may come up against.
For example, ESC 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 with water,
slush or snow, ESC 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), ESC 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, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC 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. ESC can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
drive r inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road during ex treme 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 ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

ESC includes and/or works together with the
anti-lock brake system (ABS) , brake assist sys ­
tem, anti -slip regulation (ASR) , e lectronic dif­
ferential lock ( EDL) and e lectronic interax le
d ifferential lock* . ESC is swi tched on all the
time. In certain situat ions when you need less
traction , you can switch off ASR by pressing
the button
[ru <::;> page 198, fig . 182 . Be sure
to switch ASR on again when you no longer
n eed less t raction.
Anti-lock br aking s ystem (ABS)
ABS prevents the wheels from locking up
when braking . The veh icle can still be steered
even during hard braking . Apply steady pres­
sure to the brake pedal. Do not pump the ped ­
a l. A puls ing in the bra ke peda l indicates that
the system is he lping you to brake the vehicle.
Brake assist system
The brake assist system can decrease brak ing
d istance.
It increases braking power when the
driver p resses the brake pedal quic kly in emer­
gency situations. You must press and ho ld the
b rake peda l until the situation is over . In
vehicles with adaptive cruise control* , the
brake assist system is more sensitive if the
d istance detected to the vehicle ahead is too
small.
Anti -slip regulation (ASR )
ASR reduces engine power when the d rive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
s tart, accelerate and drive up hills.
El ectronic diffe rential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive powe r to the other drive
wheel or whee ls if the vehicle is equipped with
all-whee l drive*. This function is available up
to about 75 mph (120 km/h).
I n extreme cases , ED L automatica lly switches
off to help keep the brake on the braked whee l
from overheating.
E DL wi ll switch on again au­
tomatically when conditions have returned to normal.

A WARNING
-- ESC, ABS, ASR, EDL and the electronic in­
teraxle diffe rential lock function* cannot
overcome the laws of physics. This is es­
pecially important on slippery or wet
roads . If the systems begin acting to sta­
bilize your veh icle, you should immedi­
ately change yo ur speed to match the
road and traffic cond itions. Do not let
the increased safety provided by these
systems tempt you to take risks. Do ing
so will increase the r isk o f a loss of vehi ­
cle control, collision and serious personal inju ries.
-Always adapt your speed to road, traffic and weather conditions . The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead . ESC, ABS, the brake assist sys­
tem, EDL, ASR and the e lectronic inte r­
axle d iffe ren tial lock function* cannot
preven t coll is ions.
- Always accelerate with spec ial care on
even, smooth surfaces su ch as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve-
hicle control. .,.
