108 Automatic Transmission
This prevents too much stress from being placed on the locking mechanism.
multitronic transmission : Your vehicle is
equipped with
hill hold assist allowing you to
start while on an incline. The system is acti­
vated when the brake pedal is pressed down
and held
for a few seconds. T he brake pres­
sure will hold for
o moment after the brake
pedal loosens to prevent the vehicle from roll­
ing backwards while starting up .
A 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 while in gear. If you must leave
your vehicle when the engine is running, activate the parking brake and move the
selector lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "creeping ", you
must keep your foot on the brake when
the engine is running and the selector lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the
engine is running.
- Never shift into R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases
braking distance or causes complete fail­
ure of the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake. -
Never hold the vehicle on an incline with
a slipping clutch. The clutch opens auto­
matically when it becomes too hot from
the overload . An indicator lamp
[O] illu­
minates and a driver message appears
~ page 110 when the clutch is overload­
ed.
- If the engine 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 with the parking brake set
~ page 219, Engine comportment. Oth­
erwise, any increase in engine speed may
set the vehicle in motion, even with the
parking brake applied.
(D Note
- 5 tronic ®- and tiptronic transmission :
When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear
is selected . This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake
pedal to prevent the vehicle from rolling .
- 5 tronic ®- and tiptronic transmission : Al­
lowing the vehicle to roll when the en­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv­
er's safety belt is engaged in the buckle.
Hill descent control
Applies to vehicles: with mult itronic/5 tronic/tiptronic
The hill descent control system assists the
driver when driving down declines.
Hill descent control is activated when these­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects .,.

a gear that is suitable for the incline. Hill de­
scent control tries to maintain the speed ach­
ieved at the time of brak ing, within physical
and technica l limitations. If may still be nec­
essary to adjust the speed with the brakes.
Hill descent control switches off once the de­
cline levels out or you press the accelerator pedal.
On vehicles with the cruise control system*
¢ page 79, hill descent control is also activat­
ed when the speed is set.
.&_ WARNING
-
H ill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
conditions. Always be ready to app ly the
brakes .

General information
Applies to vehicles: with Homelink® unive rsal remote
co ntrol
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 moto r signals. Programming the in­
d iv idual remote control fo r you r 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 required by federal safety stand­
ards. This includes any garage door open­
er mode l manufact ured 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 s tandards. Us ing a garage doo r
o pener witho ut these fea tures increases
risk of serious inj ury or death.
- F or safety reasons never release t he
parking brake or s tart the engine while
anyone is standing in front of the vehicle .
- A garage door or an est ate gate may
sometimes be set in motion when the Homelink

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 146 Unbelted occupants in a ve hicle heading for a
wall
Fig. 147 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¢
fig. 146, they will keep
moving at the same speed the vehicle was
moving just before the crash, until something
stops them - here, the wall ¢
fig. 147.
Safety belts 13 7
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. 148 A driver not wea ring a safety be lt is vio lently
thrown forward
Fig. 149 A rear passenger not wearing a safety belt
w ill fly forward and strike the driver
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 .,..

138 Safety belts
occupant will slam violently into the steering
wheel, instrument panel, windshield, or what­
ever else is in the way
c::> fig. 148. This impact
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. 149. 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. 150 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!

ESC includes and/or works together with the
anti-lock brake system (ABS) , brake assist sys ­
tem, anti -slip regulation (ASR) , electronic dif­
ferential lock (E DL) and e lectronic interaxle
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 ~ fig . 177 . Be sure to switch
ASR on again when you no longer need less
traction.
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered even during hard braking . Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal 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 presses the brake pedal quickly in emer­
gency situations. You must press and hold the
brake pedal 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 drive
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.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinn ing and
transfers the drive power 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 , EDL automatically switches
off to help keep the brake on the braked wheel
from overheating. EDL wi ll switch on again au­
tomatically when conditions have returned to
normal.
Intelligent technology 193
Electronic interaxle differential lock*/
selective wheel torque control*
The electronic interaxle differential lock (front
whee l drive) or the se lective wheel torque
cont rol (all-wheel dr ive) operates when dr iv­
ing through curves . The front wheel on the in­
s ide of the curve or both wheels on the inside
of the curve are braked selectively as needed .
T his min imizes sliding in the front wheels and
allows for more precise driving through
curves . Th e applicable system may no t acti­
vate when driv ing in wet or snowy conditions.
A WARNING
-
-ESC, ABS, ASR, EDL and the electronic in­
teraxle differential 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 vehicle, you should immedi­
ately change your speed to match the
road and traffic conditions. Do not let
the increased safety provided by these
systems tempt you to t.;1ke risks. Doing
so will increase the risk o f a loss of vehi­
cle control, collision and serious personal
injuries.
-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 iving too close to vehicles up
ahead . ESC, ABS, the brake assist sys­
tem, EDL, ASR and the elec tronic inter­
axle differential lock function* cannot
prevent collisions .
- Always accelerate with special care on
even, smooth surfaces such 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. .,.
