126  Automatic  transmission 
8_ WARNING 
-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 preven t 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 128when  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 
r:::> page  231 . Otherwise,  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 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 . 
- Allowing  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. 
@ 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 
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  braking,  within  physical 
and technical  limitations.  It  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. 
When  the speed is set  in the  cruise control 
system 
r:::> page  95, hill  descent control  is also 
activated. 
A WARNING 
-
Hill  descent  control  cannot  overcome 
physical limitations,  so  it may not  be able 
to  maintain  a constant  speed under  all

Homelink 
Universal  remote 
control 
Description 
Applies  to  vehicles:  with  Home link 
The HomeLink  universal  remote  control can 
be programmed  with  the  remote  control for 
devices  that  are  already  present. 
With  Home Link, 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  rep lace 
three  different  remote  controls  from  dev ices 
in  your  home  with  one  universal  remote.  This 
feature  works  for  most  garage  door and  exte
rior door  motor  signals.  Programming  the  in
dividual  remote  control  for  your  remote  con 
trol  takes  place  near  the  center  of the  radiator 
grille.  There  is a  control  module  attached  at 
this  location . 
A one-time  programming  of  the  sensor  must  be  performed  before  you  are  able  to  use sys
tems  with  Homelink.  If  the  system  does  not  activate  after  performing  the  one-time  pro
gramming,  check  whether  the  system  uses  a rolling  code¢ 
page  138 for  vehicles  without 
the  MMI*.

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 . Using  a  garage  door 
opener  without  these features  increases 
risk  of serious  injury  or  death. 
Homelink  135 
- For safety  reasons  never  release  the

sometimes  be  set  in motion  when  the 
Homelink  remote  control  is being  pro
grammed.  If  the device  is repeatedly  ac
tivated,  th is can  overstrain  motor  and 
damage  its  electrical  components - an 
overheated  mo to r i s  a fire  hazard! 
- To avoid  possib le  injuries  or  property 
damage,  please  always  make  abso lutely

- the  incline  is 10%. 
A WARNING 
-Always adapt  your  speed to  the weather, 
road  and traffic  conditions . Do  not  let 
the  increased  safety provided  tempt  you 
into  taking  r isks. 
- The  hill descent assist system  cannot 
overcome  the  laws of  physics. Your driv
ing  style  must  always be adapted  to  the 
current  road  and traffic  conditions. 
- The  hill  descent assist  may not  be able to 
hold  your  vehicle  at  a constant  speed  un
der all  condit ions wh ile driving  on an in
cl ine (for  example  if  ground  under  the 
vehicle  is  loose). 
Brake  system 
Operating  conditions  and driving  habits 
The brakes on today's  automobiles  are st ill 
subject  to  wear, depending  largely on operat
ing conditions  and dr iv ing  habits ¢& . On 
veh icles  that  are e ither  driven  mostly  in stop
and-go  city  traffic  o r are driven  hard, the 
brake  pads should  be checked  by your author- ized Audi  dealer  more  often 
than specified  in 
the 
Warranty & Maintenance booklet. Failure 
to  have your  brake pads inspected  can result 
in  reduced  brake performance. 
On steep slopes, you should  use  the  braking 
effect  of  the  engine.  This way, you  prevent  un
necessary wear  on the  brake system.  If  you 
must  use your  brakes, do not  hold  the  brakes 
down  cont inuously.  Pump the  brakes at  inter
vals . 
Noises  may occur when  braking  depending on 
the  speed,  braking  force  and outside  condi
tions  such as temperature  and  humidity. 
Moisture  or  road salt 
Under  certain  conditions,  for  example,  when 
driving  through  water  or very  heavy rain,  or 
even after  washing  your  vehicle,  the  braking 
effect  can be  reduced due to  moisture  (or in 
freezing  cond itions  ice) on the  brake pads. A 
few  careful  brake applications  should  dry 
off 
the  brake pads or  remove any ice coatings . 
When  you are  driving at  higher  speeds with 
the  windshield  wipers  on, the  brake pads will 
briefly  touch  the  brake discs in  regular  inter 
vals so  as to improve  reaction time  when  brak
ing  on wet  surfaces.  You, the  driver, will  not 
notice  anything. 
The effectiveness  of  the  brakes can be reduced 
when  the vehicle is  driven  on a salt-covered 
road  and the  b rakes are not  used.  Here too, 
you should  clean 
off accumulated  sa lt coating 
from  brake discs and  pads with a few  careful 
applications  of  the brake ¢& . 
Corrosion 
The re  may  be a tendency  for  dirt  to  build  up 
o n  the  brake  pads and corrosion  to  form  on 
the  discs  if the  car is not  driven  regularly or 
only  for  short trips with  littl e use of  the 
brakes. 
If the  brakes a re  not  used  frequently,  o r if cor
rosion  has formed  on the  discs, it  is adv isable 
to  clean 
off the  pads  and discs  by braking 
firmly  a  few times  from  a modera tely  high 
speed ¢£ .

208  Driving  and  environment 
Reducing unnecessary idling 
Even when your  car is just  idling it  burns  up 
fuel. 
.,. Shut  the  engine off when  you are not  driving 
the  vehicle. 
.,.  Do not  warm  up the  vehicle  by letting  the 
engine  run at  idle . 
The idling  phase is automatically  reduced for 
vehicles  with  the  Start-Stop -System* . It  is ef
fic ient  to sw itch 
off the  eng ine  in vehicles 
without  the  Start-Stop-System*  when  stopped 
at  railroad  crossings  and long  red lights.  Turn
ing  the  eng ine 
off for  just  30-40  seconds 
saves more  fuel  than  is burned  by sta rting  the 
engine  again . 
It takes a long  time  for  the engine  to  wa rm  up 
fu lly when  it  is  running  at  idle. However , wear 
and  nox ious emissions  are especially  high 
when  the  engine  is warming  up. So you  should 
drive  away as soon as you  start  the  engine  and 
avoid  running  at  high  rpms while  the  engine  is 
still  warming  up. 
(D Note 
Do  not  leave engine  idling  unattended  af
ter  starting.  If  warning  lights  should  come 
on to  indicate  improper  operation,  they 
would  go  unheeded.  Extended idling also 
produces  heat,  which  could  resu lt in over
heat ing or  other  damage  to  the vehicle  or 
other  property . 
Regular  maintenance 
A badly  tuned  engine  unnecessarily  wastes  a 
lot  of  fuel . 
.,. Have your  vehicle  serviced  at  regular  inter-
vals. 
By having your  vehicle  regularly  serviced  by an 
author ized Audi  dealer  helps to  ensure that  it 
runs  properly  and economically . The condition 
of  your  vehicle  not  only  affects  its  safety  and 
ab ility  to  hold  its value,  it  also affects 
fuel 
consumption.  Check 
your oil  each  time  you  fill your  tank. 
The amount  of  oi l used  is re lated  to engine 
load  and  speed. 
It  is normal  for  the  oil  consumption  of  a new 
engine  to  reach its lowest  value  after  a certa in 
mileage  has been driven . 
You must  drive your  veh icle about  3,000  mi les 
(5,000  kilometers)  before  you can properly 
assess oil  consumpt ion. 
This also app lies to  fuel  consumption  and en
gine  output . 
(0 Note 
- Have your  veh icle  ma inta ined properly 
and in  accordance with  the  service rec
ommendations  in your  Warranty 
& Ma in
tenance  booklet.  Lack of  proper  ma inte
nance as well  as improper  use  of the  ve
hicle  will  impair  the  function  of  the 
em iss ion  control  system  and could  lead 
t o  damage. 
- Do not  alter  or  remove any  component of 
the  Emission  Control System  unless ap
proved  by the  manufacturer. 
- Do not  alter  or  remove any device, such 
as heat  shie lds , switches,  ignition  wires, 
valves, which  are designed  to protect 
your  vehicle's  Emission  Control System 
and other  important  vehicle  compo
nents. 
' Fewer short  trips 
Fuel  consumption  will always  be  relatively 
high  on short  trips. 
...  Try  to  avoid  driving  sho rt  distances  w it h  a 
cold  engine . 
T he eng ine and  catalytic  converter  have  to 
reach  their  optimal 
operating  temperature to 
reduce  fuel  consumpt ion  and  nox ious emis
sions effectively. 
Jus t after  starting,  a cold engine in a  mid-s ize 
car  only  achieves  a fuel economy  of  6-8  mi les 
per gallon  (30 -40 l/100  km). After  about  a 
half  a mile,  fuel  economy  climbs  to  12 mpg  .,..
